02 March 2022
New research shws that the cst f raising a child in China is nearly seven times its GDP per capita(人均国内生产总值), far mre than in the United States and Japan.
GDP, r grss dmestic prduct, is the measure f the ttal value f gds and services in a cuntry. GDP per capita is a measure resulting frm GDP divided by the size f a natin’s ttal ppulatin.
The high cst f child-raising is ne mre difficulty Chinese plicymakers (决策者) face as they try t deal with quickly decreasing(递减的) birth rates (比率).
Experts warn China’s aging ppulatin will put pressure n its health and scial security (保障) systems. A decrease in wrkers culd als seriusly limit grwth fr the wrld’s secnd largest ecnmy (经济) in the cming years.
New plicies allw families t have as many as three children. But China’s birth rate drpped t 7.52 births per 1,000 peple in 2021. That is the lwest since the Natinal Bureau f Statistics (国家统计局) began recrding the infrmatin in 1949.
The high csts f raising a child have caused fficials in China t place restrictins(限制) n the private tutring industry (私人家教行业). Sme areas have been giving cuples mney fr having a secnd r third child.
The average cst f raising a child t the age f 18 in China in 2019 was 485,000 yuan fr a first child. That is 6.9 times China’s GDP per capita that year. That infrmatin cmes frm a recent reprt frm the YuWa Ppulatin Research Institute(学院，机构) in Beijing.
China ranks secnd highest amng the 13 cuntries included in the study. The cuntry is behind nly Suth Krea, which has the lwest birth rate in the wrld. The United States number, based n 2015 data(数据), is at 4.11 times GDP per capita. Japan stands at 4.26, based n data frm 2010.
Child raising csts are even higher in China’s majr cities, reaching mre than 1 millin yuan in Shanghai and 969,000 yuan in Beijing. Birth rates in the tw cities are even lwer than the natinal average.
YuWa warned the decreasing birth rate wuld “prfundly affect (严重影响)” China’s ecnmic grwth ptential(潜力), its ability t create and its welfare(福利) prblems.
The study fund that China wuld need t spend at least 5 percent f its yearly GDP t prvide reasns fr cuples t have mre children. That wuld include educatin funding, special husing lan (贷款) rates and tax breaks(税收减免). Other cnsideratins include equal time fr mthers and fathers t be away frm their jbs and the building f mre childcare centers.
26．The GDP f China was 16926.4 billin dllars in 2021, and the ppulatin f China was abut 1.4 billin. S hw much was the cst f raising a child in China in 2021?
A．Abut ￥12,090B．Abut ￥84,630.
C．Abut $12,090.D．Abut $84,630.
27．Which f the fllwing can directly affect the decreasing birth rates f China?
A．GDP per capita.
B．The size f a natin’s ttal ppulatin.
C．The high cst f child-raising.
D．The ttal value f gds and services in a cuntry.
28．Which cuntry ranked the highest cst f raising a child in 2019?
A．China.B．Suth Krea.C．The United States.D．Japan.
29．Which f the fllwing statements is NOT true accrding t the passage?
A．The decreasing birth rate is gd fr China’s ability t create.
B．The Natinal Bureau f Statistics f China was funded in 1949.
C．The cst f child-raising in Shanghai is higher than that in Beijing.
D．The high cst f child-raising has smething t d with the lw birth rate.
【答案】26．D 27．C 28．B 29．A
【导语】本文主要介绍了中国面临出生率低的困境，以及由此带来的经济和社会问题。
26．推理判断题。根据“GDP per capita is a measure resulting frm GDP divided by the size f a natin’s ttal ppulatin.”及“New research shws that the cst f raising a child in China is nearly seven times its GDP per capita”可知，在中国抚养一个孩子的成本是人均GDP的近7倍，人均GDP是国内生产总值除以一个国家的总人口数的结果。在本题中，国内生产总值为169264亿美元，人口约14亿，那么人均GDP约12090美元，所以抚养孩子的成本约为84630美元。故选D。
27．细节理解题。根据“The high cst f child-raising is ne mre difficulty Chinese plicymakers face as they try t deal with quickly decreasing birth rates.”可知，抚养孩子的高成本可以直接影响中国的低出生率。故选C。
28．细节理解题。根据“The average cst f raising a child t the age f 18 in China in 2019 was 485,000 yuan fr a first child…That infrmatin cmes frm a recent reprt frm the YuWa Ppulatin Research Institute in Beijing.…The cuntry is behind nly Suth Krea, which has the lwest birth rate in the wrld.”可知，2019年的一份关于抚养孩子成本的报告中指出，抚养孩子成本最高的国家是韩国。故选B。
29．推理判断题。根据“A decrease in wrkers culd als seriusly limit grwth fr the wrld’s secnd largest ecnmy in the cming years.”可知，人口数量的减少会导致劳动力的减少，劳动力的减少会限制中国经济的发展；故“出生率的下降有利于中国的创造能力”是不正确的。故选A。
B
The Chinese gvernment ends its ne-child plicy （政策） and allws families t have three children. The plicy is meant t balance ppulatin develpment, stp a falling birth rate（出生率）and strengthen the Cuntry’s labr frce（劳动力）.
China, with the largest ppulatin in the wrld, started the ne-child plicy in 1980. But the gvernment allwed nly a small number f cuples t have tw children. Fr example, sme families in the cuntryside culd have tw children, if the first-brn child is a girl. In 2016, the Chinese gvernment gave ther cuples a chance t have tw children if ne f them was an nly child. Because f aging f ppulatin, in 2021, it allwed families t have three children.
T the newest plicy, different families have different pinins. “T many yung peple in the cities are n lnger interested in having tw r three children,” an fficial said. “Peple in the cuntryside are mre interested.”
At the end f 2021, China had a ppulatin f mre than 1.4 billin peple. A ttal f 900 millin f them have jbs. But the labr market ppulatin will drp in 30 years. That is t say, the cuntry will be in great need f labr by the year 2050. With the three-child plicy, an increase in births can slve this prblem.
Bys and girls, what d yu think f the three-child plicy? D yu want t have new-brn brthers r sisters?
30．Why des the Chinese gvernment end the ne-child plicy?
A．Because China needs a larger ppulatin.
B．Because a falling birth rate must be stpped.
C．Because mst families want t have a secnd r third child.
31．Hw lng des China take frm the ne-child plicy t the three-child plicy?
A．20 years.B．30 years.C．mre than 40 years
32．Hw d mst yung peple in the cities react （反应） t the three-child plicy?
A．They strngly supprt the plicy.
B．They dn’t think it is gd.
C．They’re nt interested in it any mre.
33．When will ur cuntry be seriusly shrt f labr if ne-child plicy cntinues?
A．In 2035.B．In 2050.C．In 2070.
34．What may happen after we have the “three-child” plicy?
A．The ppulatin develpment will be balanced.
B．The labr market ppulatin will drp.
C．There will be mre ld peple.
【答案】30．B 31．C 32．C 33．B 34．A
【导语】本文是一篇新闻报道，主要讲述的是中国结束独生子女政策并且实行全面开放二胎和三孩政策，以及这种政策的原因。
30．细节理解题。根据“The plicy is meant t balance ppulatin develpment, stp a falling birth rate （出生率） and strengthen theCuntry’s labr frce （劳动力）.”可知，中国政府终止独生子女政策是因为必须阻止出生率的下降。故选B。
31．细节理解题。根据“China, with the largest ppulatin in the wrld, started the ne-child plicy in 1980.”和“In 2016, the Chinese gvernment gave ther cuples a chance t have tw children if ne f them was an nly child. Because f aging f ppulatin, in 2021, it allwed families t have three children.”可知，中国从独生子女政策到三孩政策经历了四十多年。故选C。
32．细节理解题。根据“‘T many yung peple in the cities are n lnger interested in having tw r three children,’ an fficial said.”可知，城市中的大多数年轻人对三孩政策不感兴趣。故选C。
33．细节理解题。根据“That is t say, the cuntry will be in great need f labr by the year 2050. With the three - child plicy, an increase in births can slve this prblem.”可知，如果独身子女的政策继续下去，我们国家到2050年会严重缺乏劳动力。故选B。
34．细节理解题。根据“That is t say, the cuntry will be in great need f labr by the year 2050. With the three - child plicy, an increase in births can slve this prblem.”可知，也就是说，到2050年，这个国家将非常需要劳动力。在三孩政策下，增加出生率可以解决这个问题，由此推出国家实行“三孩”政策后，人口发展将达到平衡。故选A。

39．S it has
【导语】本文为吉姆和丽塔两人的对话。主要谈论了在报纸上看到的关于世界人口的问题。
35．根据“I’m reading tday’s newspaper”可知，吉姆在询问丽塔在那里做什么，此时应用特殊疑问词what进行提问，句子时态为现在进行时，故谓语应用“be ding”结构，由于句子主语为“你”yu，故应用be动词中的are，“那里”there。故填What are yu ding there。
36．根据“Yes. There’s a reprt abut the ppulatin f the wrld”可推测出，此处在询问有什么新的事情发生，可用there be句型，结合情境可知，句子应为一般疑问句，故主语为“某事”anything，谓语动词应用is，“新的”new，此时“new”应放在不定代词“anything”之后，be动词is放于句首。故填Is there anything new。
37．根据“The ppulatin is increasing faster and faster”和“If the ppulatin is increasing like this, it will be the biggest prblem n earth”可推测出，空格处为丽塔认为吉姆说的是事实，“的确是这样”That’s true。故填That’s true。
38．根据“ cuntries are taking measures t cntrl the ppulatin. Fr example...”可知，此处在举例国家为控制人口而采取的措施，根据“If every family has nly ne baby, it will be better in the future”可推测出，空格处举例的是中国已经实施了独生子女政策，“中国”China；“已经实行”have/has carried ut；“独生子女政策”the ne-child plicy。由于句子主语“China”为第三人称单数，故谓语应用has carried ut。故填China has already carried ut the ne-child plicy。
39．根据“If every family has nly ne baby, it will be better in the future”可推测出，空格处为吉姆在附和丽塔说的例子，“（中国）的确如此”S it has。故填S it has。
