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
was
formed
at
that
time.
The
West
Lake
is
quite
big
and
features
different
classic
views
from
different
locations.
Technically,there
are
ten
scenes

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
policy
brings
Chengdu
biz,tourism
boost.
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
Road
economic
belt
to
boost
cooperation.
The
idea
has
been
widely
echoed
in
Central
Asian
countries,becoming
an
encouraging
blueprint
for
Chinese
areas
along
the
Silk
Road
that
has
linked
Asia
and
Europe
for
more
than
2,000
years.
In
the
next
three
weeks,China
Daily
reporters
will
travel
through
the
belt
in
China
and
in
Kazakhstan,Uzbekistan
and
Turkey.
They
will
show
the
progress
and

of
the
countries,businesses
and
peoples
on
the
route.

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.
