五、问答及分析题(共30分，每小题10分)

1．城市轨道交通对信号系统的要求是什么?

城市轨道交通，尤其是地下铁道因其固有的特点，对其信号系统提出了如下要求：安全性要求高；通过能力大；保证信号显示；抗干扰能力强；可靠性高；自动化程度高；限界条件苛刻。

2．简述计算机联锁控制系统的联锁功能。

计算机联锁控制系统的联锁功能包括如下几点：

(1)联锁逻辑运算：接．收ATS或车站值班员的进路命令，进行联锁逻辑运算，实现对道岔和信号机的控制

(2)轨道电路信息处理：处理列车检测功能的输出信息，以提高列车监测信息的完整性；

(3)进路控制：设定、锁闭和解锁进路；

(4)道岔控制：解锁、转换和锁闭道岔；

(5)信号机控制：确定信号机的显示。

3．简述列车定位的流程。

列车定位流程可以描述为：

(1)车载ATP启动时，列车未定位，但是车载计算机单元的线路数据库记录有应答器的位置。

(2)一旦列车连续经过两个应答器，就初始化它的位置参数，这样列车“已定位”。第一个应答器初始化应答器和查询器天线的位置，但是列车不知道自己在轨道上的运行方向；根据线路数据库里应答器的顺序，第二个应答器确定列车运行方向。通过第二个应答器后，列车位置可由测速电机和雷达测量。

(3)在两个应答器之间，已定位的列车位置参数得到更新，这都得益于测速电机和雷达的连续位移测量。当经过另外一个应答器时，一列已定位的列车将调整它的位置参数，以便得到更加精确的位置。

Indonesia

has

emerged

as

a

top

vacation

destination

for

Chinese

this

summer,along

with

Thailand

s

Phuket

island

and

the

Maldives

archipelago.

Encouraged

by

growth

in

Chinese

travelers

to

Indonesia,the

government

in

Jakarta

has

recently

relaxed

its

visa

policy.

Since

June

10,Chinese

tourists

can

enter

Indonesia

through

nine

appointed

locations,including

the

Soekarno

Hatta

International

Airport

in

Jakarta,the

Ngurah

Rai

International

Airport

in

Bali

and

the

Kuala

Namu

International

Airport

in

Medan,by

just

getting

their

passports

stamped

on

arrival.

Officially,it

is

called

the

“free-visa“scheme.

The

new

policy

also

means

Chinese

tourists

can

save

$35

on

visa

fees,which

will

likely

make

trips

to

Indonesia

more

alluring.

While

such

an

arrangement

allows

Chinese

visitors

to

stay

up

to

30

days

for

the

purpose

of

traveling,those

seeking

extensions

will

need

to

get

paid

visas

from

that

country

s

missions

inBeijing,Shanghai,Guangzhou

or

Hong

Kong,according

to

an

official

at

the

Indonesia

embassy

in

Beijing.

Santo

Darmosumarto,head

of

the

embassy

s

information,social

and

cultural

section,says

the

new

policy

is

aimed

at

strengthening

people-to-people

contacts

between

the

two

countries.

Dai

Yu,marketing

director

of

Ctrip,a

major

Chinese

online

travel

agency,says:

“We

ve

seen

a

nearly

50

percent

growth

over

the

previous

month

in

the

number

of

Chinese

tourists

to

Bali

since

the

policy

was

announced.“During

his

trip

to

China

in

March,Indonesian

President

Joko

Widodo

proposed

that

his

country

and

China

aim

to

increase

two-way

visits

to

a

maximum

of

10

million

people

in

the

next

few

years.

The

Indonesian

government

has

set

their

sights

on

greeting

2

million

Chinese

tourists

by

the

end

of

this

year,according

to

the

official.

“The

Indonesian

government

hopes

that

Indonesian

nationals

would

also

be

given

preferential

treatment

while

visiting

China,“says

Darmosumarto.

In

2013,the

number

of

Chinese

tourists

who

visited

Indonesia

stood

around

807,000.

Last

year,it

increased

to

959,000,he

adds.

Bali

remains

the

most

popular

site

among

Chinese

tourists.

In

February,more

than

92,200

Chinese

tourists

made

trips

to

Bali,ranking

first

among

overseas

visitors,the

Bali

Times

reported.

Last

year,the

island

witnessed

more

than

586,000

arrivals

from

China,an

increase

of

51

percent

over

2013.

“Bali

isn

t

just

for

sightseeing,but

also

for

weddings,honeymoons,golf

and

many

outdoor

activities,“says

Fan

Wenqing,a

marketing

executive

at

Garuda,Indonesia

s

national

airliner.

Garuda

offers

three

nonstop

flights

between

Beijing

and

Bali,and

four

each

week

between

Beijing

and

Jakarta.

There

are

daily

flights

from

Guangzhou,in

Guangdong

province,and

Shanghai

to

Jakarta

as

well.

It

takes

from

six

to

eight

hours

on

a

nonstop

flight

to

reach

Indonesia

from

China.

Indonesia

is

home

to

more

than

17,000

islands.

Tourists

can

tour

Yogyakarta

to

see

Prambanam

and

Borobudur,two

historical

and

religious

sites,and

explore

the

local

handicraft

markets.

The

base

of

a

volcano,Bandung,which

is

also

known

as

the

“Paris

of

Java“,is

ideal

for

adventure-seekers.

Many

ecotourism

destinations,such

as

Toba

Lake

in

Sumatra,Tanjung

Puting

National

Park

in

Kalimantan

and

Bunaken

in

Manado,are

places

the

embassy

official

recommends

for

tourists.

Indonesia

boasts

world-class

surfing

facilities

along

the

shores

of

Sumatra

down

to

Nusa

Tenggara

Islands.

Recently,Lombok,a

sister

island

east

of

Bali

has

gotten

so

much

attention

from

Chinese

travelers

that

some

travel

agencies

are

offering

twin

packages

for

Bali

and

Lombok.

The

best

time

to

visit

Bali

is

from

May

to

October,when

it

doesn

t

rain

much

and

the

weather

is

cool.

At

press

time,a

weeklong

package

from

Shanghai

or

Guangzhou

to

Bali

was

a

little

more

than

3,000

yuan

($480)

on

Ctrip

s

website.

Chinese

tourists

have

taken

a

shine

to

rafting

in

Ubud,sightseeing

in

Tanah

Lot,and

surfing

and

diving

in

Nusa

Lembongan,says

Dai.

Civet

coffee,essential

oil

and

woodcarvings

are

among

the

most

popular

products

for

Chinese

tourists

in

Indonesia,she

says.

Indonesian

food

is

also

something

that

visitors

shouldn

t

miss.

Local

cuisines

feature

many

spices,including

peppers

and

cloves,and

coconut

pulp.

Fried

rice,“dirty

duck“and

roast

suckling

pig

are

recommended.

Children

s

illustration

books

first

appeared

in

the

1600s

in

Europe.

Their

passage

to

China,however,took

much

longer,roughly

300

years.

In

China,children

s

illustration

books

have

a

history

of

just

100

years

and

their

development

can

be

divided

into

four

stages.

From

early

1900s

to

mid

1900s,a

large

number

of

books

and

magazines

with

illustrations

appeared

with

the

fast

development

of

the

modern

publishing

industry.

The

illustration

arts

at

that

time

were

a

mixed

genre

of

Chinese

traditional

paintings

and

the

western

style,and

most

of

the

stories

originate

from

the

fundamental

changes

that

China

experienced

after

the

collapse

of

Qing

Dynasty

(1644-1911),the

warlord

struggles

and

the

war

against

the

Japanese

invasion.

The

second

stage

was

from

mid

1900s

to

late

1970s,when

the

“cultural

revolution“(1966-76)

ended.

The

fast

development

of

some

special

publishing

houses

for

children

gave

birth

to

a

large

number

of

illustration-story

books,which

made

a

good

use

of

folk

art

techniques,such

as

wood

board

carving,frescoes,and

ink

and

wash

painting,etc.

Many

of

the

popular

stories

are

from

Chinese

history

and

wars

after

1900s.

The

third

stage

is

from

early

1980s

to

late

1990s,a

golden

period

for

the

development

of

children

s

illustration

books.

The

reform

and

opening-up

brought

in

new

concepts

and

ideas

from

the

West

to

China,a

country

that

had

been

closed

to

the

West

for

nearly

three

decades.

Fast

development

of

economy,society

and

culture

provided

the

writers

and

painters

with

a

lot

of

inspiration

to

create

new

literature

works

and

draw

illustrations.

China

also

imported

large

amounts

of

children

s

illustration

books

from

the

West

and

Japan.

Many

young

parents

in

China

have

a

strong

nostalgia

about

children

s

illustration

books

they

read

in

the

1980s

and

1990s.

This

is

also

the

last

era

in

China

s

artistic

innovation

before

the

advent

of

the

Internet

period.

The

fourth

stage

is

featured

with

the

spread

of

the

Internet

and

the

other

computerized

means

of

art

innovation.

The

hand-drawn

children

s

illustration

books

are

gradually

replaced

by

cartoons

drawn

and

copied

by

software

and

machines,and

shown

on

tablets,computers,television

and

smart

phones,instead

of

books.

Hainan

Tropical

Wildlife

Park

and

Botanical

Garden

is

nature

s

haven,with

no

less

than

4,000

rare

birds

and

animals

representing

200

species.

With

tropical

forest

covering

over

90

percent

of

its

area,the

garden

offers

beautiful

views

of

a

wide

range

of

tropical

plants,flowers

and

fruit

trees.

The

scenic

spot

about

25

kilometers

from

the

center

of

Haikou

offers

a

drive-thru

safari

tour

where

you

can

get

up

close

with

elephants,lions

and

bears.

The

“Safari

on

Foot“area

features

walking

trails

where

visitors

can

see

the

rest

of

the

animals,including

hippos

and

monkeys,and

feed

them

for

a

small

fee.

Visitors

also

can

see

what

happens

when

you

breed

a

lion

and

a

tiger.

Two

unique

attractions

are

rare

hybrids:

a

liger,the

offspring

of

a

mallion

and

a

female

tiger

and

a

tigon,which

is

created

by

a

female

lion

and

a

male

tiger.

As

a

teaching

center

of

the

National

Popular

Science

Education

program,the

park

also

serves

as

a

second

classroom

for

students

to

learn

about

wildlife

and

plants.

Since

it

was

established

in

1995,it

has

received

more

than

one

million

student

visitors.

At

a

crucial

moment

when

pessimism

has

brought

the

Greek

crisis

to

such

a

head

that

the

country

is

closer

to

a

default

on

its

debt

repayments

than

ever,Li

offered

a

spark

of

enthusiasm

to

restart

the

stalled

talks

by

calling

on

Greece

and

its

creditors

to

reach

a

last-minute

deal

that

will

allow

Greece

to

remain

in

the

eurozone.

Given

the

escalation

of

the

country

s

crisis

over

the

weekend

sent

a

shock

wave

through

the

global

stock

markets

on

Monday,there

are

ample

reasons

to

worry

about

the

uncertainties

surrounding

the

events

in

Greece

and

the

effect

a

default

would

have

on

Europe,relations

between

China

and

the

EU,global

financial

stability

and

the

nascent

global

economic

recovery.

Greece

has

announced

that

it

will

hold

a

referendum

on

a

bailout

plan

proposed

last

week

by

the

country

s

creditors.

In

response,Greece

s

eurozone

partners

have

refused

to

extend

the

country

s

bailout

program

and

the

European

Central

Bank

capped

its

emergency

support

for

the

country

s

banks.

A

real

danger

now

looms

of

Greece

exiting

the

euro,which

might

derail

the

global

economic

recovery

and

damage

the

long-term

viability

of

the

euro

as

a

currency.

However,such

a

tragedy

is

neither

certain

nor

unavoidable.

The

EU

should

shoulder

its

responsibility

to

prevent

the

Greek

crisis

from

overshadowing

the

fragile

global

recovery.

As

a

major

customer

and

supplier

of

the

28-nation

EU,and

a

responsible

long-term

holder

of

Eurobonds,China

s

confidence

in

and

commitment

to

a

strong

eurozone

offers

EU

leaders

the

necessary

support

to

look

at

the

Greek

crisis

from

a

broader

and

longer

perspective.

When

Li

said

that

China

will

not

only

consider

a

China-EU

investment

platform

to

back

European

Commission

President

Jean-Claude

Juncker

s

plan

to

revive

the

European

economy,but

also

buy

more

bonds

issued

by

the

European

Investment

Bank,EU

leaders

should

be

clear

that

China

wants

to

see

the

EU

maintain

its

integrity

and

a

forward

trajectory.

Such

a

confidence-building

effort

is

particularly

valuable,especially

from

such

a

large

country

as

China

which

already

has

a

huge

stake

and

seeks

to

further

expand

it

in

a

strong

eurozone.

It

will

be

a

tragedy

to

allow

inaction

over

the

Greek

crisis

to

stand

in

the

way

of

growth-boosting

Sino-EU

cooperation.

Like

a

shining

pearl,West

Lake

is

the

symbol

of

Hangzhou

city.

From

ancient

times,many

poems

have

praised

the

amazing

scenery

of

the

lake.

At

the

very

beginning,the

West

Lake

was

a

part

of

the

Qiantang

River.

In

the

year

822,Bai

Juyi,a

famous

poet

and

an

officer

of

the

Tang

Dynasty

(AD

618-907),suggested

to

build

a

stronger

causeway

to

store

water

so

that

the

lake

was

doubled

in

size.

And

during

the

Song

Dynasty

(AD

960-1279),many

temples

and

pagodas

were

built

due

to

a

Buddhist

revival,and

the

look

of

West

Lake

卫生统计学：是运用数理统计的基本原理和方法，通过数据的收集，整理和分析，研究预防医学和卫生事业管理中随机现象规律性的一门应用科学。

2.

随机抽样：就是按照随机的原则获得样本，保证总体中每个个体都有同等机会被抽取，使样本对总体有较好的代表性。

3.

构成比：又称构成指标，它表示事物内部各组成部分所占比重或分布。常用百分数表示。

4.

频率：若随机事件在n次重复中出现m次，则n/m比值成为随机事件出现的频率。

5.非参数检验：是一种不依赖总体分布类型，也不对总体参数（如总体均数）进行统计推断的假设检验。

6．概率是描述随机事件发生的可能性的大小的数值，常用P表示。

7．变异系数常记为CV，它被定义为标准差与算术均数之比。

3．调查某市1999年市区400名新生儿的出生体重，得均数为3.00kg，标准差为0.50

kg；出生身长均数50cm，标准差为3cm；

试问：1）该研究的总体、样本各是什么？

2）身长和体重何者变异大？抽样误差各为多大？

3）该市市区95%的新生儿出生体重在什么范围之内？

4）该市市区的新生儿出生体重的平均水平在什么范围之内？

5）过去该市区的新生儿平均出生体重为2.90kg，问现在出生体重有无变化？

计算分析题答案

1．

该资料为构成比资料，计算医院分娩的116名畸形儿母亲的年龄分布，在这些畸形儿中母亲年龄26岁所占的比重最大，其次为24—29（除26岁以外）各年龄组（5分）。不能根据该资料得出“母亲年龄在24—29岁时，最容易出生畸形儿”的结论（5分）。若要回答哪个年龄组母亲容易出生畸形儿，需要收集各年龄母亲出生的新生儿数及畸形儿资料，计算各年龄组母亲的畸形儿发生率。

2．(1)建立假设检验，确定检验水准

H0穿新旧防护衣工人皮炎患病率相同，即∏1＝∏2

H1穿新旧防护衣工人皮炎患病率不相同，即∏1≠∏2

a=0.05

（2）计算统计量x2值

T11=(11×15)/43＝3.84

本例有一个理论频数小于5，而你n>40，故需计算校正x2值

计算得x2值等于2.94

（3）确定P值，作出推断结论

v＝（2-1）（2-1）＝1

查x2

界值表本例x2＝2.940.05，不拒绝H0，尚不能认为穿新旧防护衣工人皮炎患病率不同。

3．1）总体：某市1999年市区新生儿、样本：某市1999年市区400名新生儿

2）求身高、体重的均数，标准差，标准误。

3）求正常值范围

4）求可信区间

5）样本与总体均数=2.9的t检验

Visa-free

Making

national

headlines

several

times,Chengdu

s

72-hour

visa-free

policy

has

attracted

wide

attention

from

both

Chinese

and

foreign

experts

and

businessmen

since

it

took

effect

on

Sept

1

last

year.

The

program

permits

citizens

from

51

countries

and

regions

including

the

United

States,Australia,Canada

and

Japan

who

have

valid

visas

and

flight

tickets

to

a

third

country

to

spend

three

days

in

the

city.

The

capital

of

Sichuan

province

is

the

first

city

in

the

western

region

of

China

to

offer

foreign

tourists

a

three-day

visa

and

the

fourth

nationwide

to

adopt

the

policy

following

Shanghai,Beijing

and

Guangzhou.

Li

Zhiyong,deputy

dean

of

the

tourism

institute

at

Sichuan

University,said

the

move

“contributes

to

a

large

increase

in

the

number

of

overseas

tourists

and

raises

the

city

s

level

of

internationalization“.

“The

policy

will

also

bring

direct

economic

revenue,“Li

said.

“Chengdu

has

many

cultural

legacies

and

is

also

a

paradise

for

panda

lovers

with

the

world

s

largest

breeding

and

research

center.

Three

days

are

long

enough

for

foreign

visitors

to

visit

those

iconic

tourist

spots,“he

noted.

The

city

is

home

to

the

remains

of

the

Jin

sha

civilization

that

dates

back

more

than

3,000

years

as

well

as

the

Qing

cheng

Mountains

and

the

Du

jiang

yan

irrigation

system.

Qing

cheng

has

long

been

recognized

as

the

birthplace

of

Taoism,China

s

ancient

indigenous

religion,while

Du

jiang

yan

is

considered

to

be

the

oldest

functioning

water-control

project

in

the

world.

Chengdu

ranked

third

in

tourist

facilities,management

and

services

among

60

Chinese

cities

in

a

customer

satisfaction

survey

released

last

year.

But,Li

added

that

efforts

are

still

needed

to

develop

more

tourism

products,improve

English

services

and

provide

accurate

translation

of

traffic

signs

and

scenic

billboards.

Zhao

Yun,chairwoman

of

British

Chamber

of

Commerce

Southwest

China,told

China

Daily

that

his

colleagues

found

the

policy

very

convenient.

“A

British

client

once

flew

here

and

stayed

for

just

one

day

to

check

her

ordered

goods,“she

said.

Zhao

was

born

in

Shanxi

province,but

she

has

lived

in

Chengdu

for

more

than

10

years.

“My

life

was

like

a

running

race

moving

from

place

to

place.

I

also

lived

in

Beijing

and

Shanghai

before,“she

said.

“But

Chengdu

is

a

place

that

you

never

want

to

leave

once

settling

down.

It

is

now

my

second

hometown,“she

said.

If

the

environment

is

further

improved,the

city

will

attract

more

people

to

visit

and

live,with

the

72-hour

visa-free

policy

and

compelling

conditions

in

transportation,culture,climate

and

cuisine,he

said.

Foreigners

also

gave

positive

feedback

on

the

policy.

A

spokesman

from

Dell

Inc

said

the

company

has

a

global

hub

of

operation

in

Chengdu,so

the

three-day

visa

“has

an

immediate

and

positive

influence

on

the

company

s

business

development“.

Rudy

Buttignol,president

of

the

public

broadcasting

company

in

British

Columbia,Canada,said

his

work

requires

frequent

travel

to

Chengdu

and

the

policy

“makes

the

trips

easier“.

Data

from

the

city

s

public

security

bureau

shows

some

100

foreign

visitors

enjoyed

the

72-hour

policy

by

the

end

of

March,most

of

them

from

the

United

States,the

United

Kingdom

and

Germany.

Chengdu

also

reported

robust

growth

in

its

overall

tourist

industry

last

year.

Official

statistics

show

that

it

received

some

150

million

tourists

last

year,an

increase

of

28

percent

from

2012.

Around

1.7

million

came

from

abroad,an

increase

of

12

percent.

Total

revenue

from

tourism

surpassed

133

billion

yuan

($21.7billion).

During

his

visit

to

Kazakhstan

in

September,Chinese

President

Xi

Jinping

proposed

that

China

and

Central

Asia

join

hands

to

build

a

Silk

Indonesia

has

emerged

as

a

top

vacation

destination

for

Chinese

this

summer,along

with

Thailand

s

Phuket

island

and

the

Maldives

archipelago.

Encouraged

by

growth

in

Chinese

travelers

to

Indonesia,the

government

in

Jakarta

has

recently

relaxed

its

visa

policy.

Since

June

10,Chinese

tourists

can

enter

Indonesia

through

nine

appointed

locations,including

the

Soekarno

Hatta

International

Airport

in

Jakarta,the

Ngurah

Rai

International

Airport

in

Bali

and

the

Kuala

Namu

International

Airport

in

Medan,by

just

getting

their

passports

stamped

on

arrival.

Officially,it

is

called

the

“free-visa“scheme.

The

new

policy

also

means

Chinese

tourists

can

save

$35

on

visa

fees,which

will

likely

make

trips

to

Indonesia

more

alluring.

While

such

an

arrangement

allows

Chinese

visitors

to

stay

up

to

30

days

for

the

purpose

of

traveling,those

seeking

extensions

will

need

to

get

paid

visas

from

that

country

s

missions

inBeijing,Shanghai,Guangzhou

or

Hong

Kong,according

to

an

official

at

the

Indonesia

embassy

in

Beijing.

Santo

Darmosumarto,head

of

the

embassy

s

information,social

and

cultural

section,says

the

new

policy

is

aimed

at

strengthening

people-to-people

contacts

between

the

two

countries.

Dai

Yu,marketing

director

of

Ctrip,a

major

Chinese

online

travel

agency,says:

“We

ve

seen

a

nearly

50

percent

growth

over

the

previous

month

in

the

number

of

Chinese

tourists

to

Bali

since

the

policy

was

announced.“During

his

trip

to

China

in

March,Indonesian

President

Joko

Widodo

proposed

that

his

country

and

China

aim

to

increase

two-way

visits

to

a

maximum

of

10

million

people

in

the

next

few

years.

The

Indonesian

government

has

set

their

sights

on

greeting

2

million

Chinese

tourists

by

the

end

of

this

year,according

to

the

official.

“The

Indonesian

government

hopes

that

Indonesian

nationals

would

also

be

given

preferential

treatment

while

visiting

China,“says

Darmosumarto.

In

2013,the

number

of

Chinese

tourists

who

visited

Indonesia

stood

around

807,000.

Last

year,it

increased

to

959,000,he

adds.

Bali

remains

the

most

popular

site

among

Chinese

tourists.

In

February,more

than

92,200

Chinese

tourists

made

trips

to

Bali,ranking

first

among

overseas

visitors,the

Bali

Times

reported.

Last

year,the

island

witnessed

more

than

586,000

arrivals

from

China,an

increase

of

51

percent

over

2013.

“Bali

isn

t

just

for

sightseeing,but

also

for

weddings,honeymoons,golf

and

many

outdoor

activities,“says

Fan

Wenqing,a

marketing

executive

at

Garuda,Indonesia

s

national

airliner.

Garuda

offers

three

nonstop

flights

between

Beijing

and

Bali,and

four

each

week

between

Beijing

and

Jakarta.

There

are

daily

flights

from

Guangzhou,in

Guangdong

province,and

Shanghai

to

Jakarta

as

well.

It

takes

from

six

to

eight

hours

on

a

nonstop

flight

to

reach

Indonesia

from

China.

Indonesia

is

home

to

more

than

17,000

islands.

Tourists

can

tour

Yogyakarta

to

see

Prambanam

and

Borobudur,two

historical

and

religious

sites,and

explore

the

local

handicraft

markets.

The

base

of

a

volcano,Bandung,which

is

also

known

as

the

“Paris

of

Java“,is

ideal

for

adventure-seekers.

Many

ecotourism

destinations,such

as

Toba

Lake

in

Sumatra,Tanjung

Puting

National

Park

in

Kalimantan

and

Bunaken

in

Manado,are

places

the

embassy

official

recommends

for

tourists.

Indonesia

boasts

world-class

surfing

facilities

along

the

shores

of

Sumatra

down

to

Nusa

Tenggara

Islands.

Recently,Lombok,a

sister

island

east

of

Bali

has

gotten

so

much

attention

from

Chinese

travelers

that

some

travel

agencies

are

offering

twin

packages

for

Bali

and

Lombok.

The

best

time

to

visit

Bali

is

from

May

to

October,when

it

doesn

t

rain

much

and

the

weather

is

cool.

At

press

time,a

weeklong

package

from

Shanghai

or

Guangzhou

to

Bali

was

a

little

more

than

3,000

yuan

($480)

on

Ctrip

s

website.

Chinese

tourists

have

taken

a

shine

to

rafting

in

Ubud,sightseeing

in

Tanah

Lot,and

surfing

and

diving

in

Nusa

Lembongan,says

Dai.

Civet

coffee,essential

oil

and

woodcarvings

are

among

the

most

popular

products

for

Chinese

tourists

in

Indonesia,she

says.

Indonesian

food

is

also

something

that

visitors

shouldn

t

miss.

Local

cuisines

feature

many

spices,including

peppers

and

cloves,and

coconut

pulp.

Fried

rice,“dirty

duck“and

roast

suckling

pig

are

recommended.

Children

s

illustration

books

first

appeared

in

the

1600s

in

Europe.

Their

passage

to

China,however,took

much

longer,roughly

300

years.

In

China,children

s

illustration

books

have

a

history

of

just

100

years

and

their

development

can

be

divided

into

four

stages.

From

early

1900s

to

mid

1900s,a

large

number

of

books

and

magazines

with

illustrations

appeared

with

the

fast

development

of

the

modern

publishing

industry.

The

illustration

arts

at

that

time

were

a

mixed

genre

of

Chinese

traditional

paintings

and

the

western

style,and

most

of

the

stories

originate

from

the

fundamental

changes

that

China

experienced

after

the

collapse

of

Qing

Dynasty

(1644-1911),the

warlord

struggles

and

the

war

against

the

Japanese

invasion.

The

second

stage

was

from

mid

1900s

to

late

1970s,when

the

“cultural

revolution“(1966-76)

ended.

The

fast

development

of

some

special

publishing

houses

for

children

gave

birth

to

a

large

number

of

illustration-story

books,which

made

a

good

use

of

folk

art

techniques,such

as

wood

board

carving,frescoes,and

ink

and

wash

painting,etc.

Many

of

the

popular

stories

are

from

Chinese

history

and

wars

after

1900s.

The

third

stage

is

from

early

1980s

to

late

1990s,a

golden

period

for

the

development

of

children

s

illustration

books.

The

reform

and

opening-up

brought

in

new

concepts

and

ideas

from

the

West

to

China,a

country

that

had

been

closed

to

the

West

for

nearly

three

decades.

Fast

development

of

economy,society

and

culture

provided

the

writers

and

painters

with

a

lot

of

inspiration

to

create

new

literature

works

and

draw

illustrations.

China

also

imported

large

amounts

of

children

s

illustration

books

from

the

West

and

Japan.

Many

young

parents

in

China

have

a

strong

nostalgia

about

children

s

illustration

books

they

read

in

the

1980s

and

1990s.

This

is

also

the

last

era

in

China

s

artistic

innovation

before

the

advent

of

the

Internet

period.

The

fourth

stage

is

featured

with

the

spread

of

the

Internet

and

the

other

computerized

means

of

art

innovation.

The

hand-drawn

children

s

illustration

books

are

gradually

replaced

by

cartoons

drawn

and

copied

by

software

and

machines,and

shown

on

tablets,computers,television

and

smart

phones,instead

of

books.

Hainan

Tropical

Wildlife

Park

and

Botanical

Garden

is

nature

s

haven,with

no

less

than

4,000

rare

birds

and

animals

representing

200

species.

With

tropical

forest

covering

over

90

percent

of

its

area,the

garden

offers

beautiful

views

of

a

wide

range

of

tropical

plants,flowers

and

fruit

trees.

The

scenic

spot

about

25

kilometers

from

the

center

of

Haikou

offers

a

drive-thru

safari

tour

where

you

can

get

up

close

with

elephants,lions

and

bears.

The

“Safari

on

Foot“area

features

walking

trails

where

visitors

can

see

the

rest

of

the

animals,including

hippos

and

monkeys,and

feed

them

for

a

small

fee.

Visitors

also

can

see

what

happens

when

you

breed

a

lion

and

a

tiger.

Two

unique

attractions

are

rare

hybrids:

a

liger,the

offspring

of

a

mallion

and

a

female

tiger

and

a

tigon,which

is

created

by

a

female

lion

and

a

male

tiger.

As

a

teaching

center

of

the

National

Popular

Science

Education

program,the

park

also

serves

as

a

second

classroom

for

students

to

learn

about

wildlife

and

plants.

Since

it

was

established

in

1995,it

has

received

more

than

one

million

student

visitors.

At

a

crucial

moment

when

pessimism

has

brought

the

Greek

crisis

to

such

a

head

that

the

country

is

closer

to

a

default

on

its

debt

repayments

than

ever,Li

offered

a

spark

of

enthusiasm

to

restart

the

stalled

talks

by

calling

on

Greece

and

its

creditors

to

reach

a

last-minute

deal

that

will

allow

Greece

to

remain

in

the

eurozone.

Given

the

escalation

of

the

country

s

crisis

over

the

weekend

sent

a

shock

wave

through

the

global

stock

markets

on

Monday,there

are

ample

reasons

to

worry

about

the

uncertainties

surrounding

the

events

in

Greece

and

the

effect

a

default

would

have

on

Europe,relations

between

China

and

the

EU,global

financial

stability

and

the

nascent

global

economic

recovery.

Greece

has

announced

that

it

will

hold

a

referendum

on

a

bailout

plan

proposed

last

week

by

the

country

s

creditors.

In

response,Greece

s

eurozone

partners

have

refused

to

extend

the

country

s

bailout

program

and

the

European

Central

Bank

capped

its

emergency

support

for

the

country

s

banks.

A

real

danger

now

looms

of

Greece

exiting

the

euro,which

might

derail

the

global

economic

recovery

and

damage

the

long-term

viability

of

the

euro

as

a

currency.

However,such

a

tragedy

is

neither

certain

nor

unavoidable.

The

EU

should

shoulder

its

responsibility

to

prevent

the

Greek

crisis

from

overshadowing

the

fragile

global

recovery.

As

a

major

customer

and

supplier

of

the

28-nation

EU,and

a

responsible

long-term

holder

of

Eurobonds,China

s

confidence

in

and

commitment

to

a

strong

eurozone

offers

EU

leaders

the

necessary

support

to

look

at

the

Greek

crisis

from

a

broader

and

longer

perspective.

When

Li

said

that

China

will

not

only

consider

a

China-EU

investment

platform

to

back

European

Commission

President

Jean-Claude

Juncker

s

plan

to

revive

the

European

economy,but

also

buy

more

bonds

issued

by

the

European

Investment

Bank,EU

leaders

should

be

clear

that

China

wants

to

see

the

EU

maintain

its

integrity

and

a

forward

trajectory.

Such

a

confidence-building

effort

is

particularly

valuable,especially

from

such

a

large

country

as

China

which

already

has

a

huge

stake

and

seeks

to

further

expand

it

in

a

strong

eurozone.

It

will

be

a

tragedy

to

allow

inaction

over

the

Greek

crisis

to

stand

in

the

way

of

growth-boosting

Sino-EU

cooperation.

Like

a

shining

pearl,West

Lake

is

the

symbol

of

Hangzhou

city.

From

ancient

times,many

poems

have

praised

the

amazing

scenery

of

the

lake.

At

the

very

beginning,the

West

Lake

was

a

part

of

the

Qiantang

River.

In

the

year

822,Bai

Juyi,a

famous

poet

and

an

officer

of

the

Tang

Dynasty

(AD

618-907),suggested

to

build

a

stronger

causeway

to

store

water

so

that

the

lake

was

doubled

in

size.

And

during

the

Song

Dynasty

(AD

960-1279),many

temples

and

pagodas

were

built

due

to

a

Buddhist

revival,and

the

look

of

West

Lake

was

formed

at

that

time.

The

West

Lake

is

quite

big

and

features

different

classic

views

from

different

locations.

Technically,there

are

ten

scenes

which

were

marked

by

Emperor

Qianlong

with

four-character

inscriptions

200

years

ago,such

as

the

Melting

Snow

on

the

Broken

Bridge

and

Sunset

Glow

over

Leifeng

Pagoda.
