The baby boy, born at two minutes past midnight Thursday in a Beijing hospital, counted China’s 1.3 billionth citizen and the date, January 6, 2005, became the 1.3 Billion Population Day of China.

With 3,600 grams and 52 cm, the boy is in good condition. So far, the boy has no name. His mother is Lan Hui in her 31 with the Shell Group of Companies and the boy’s father is one staff from Air China.

"I am very happy, and I am the happiest man in the world," the boy’s father said.

Gu Xiulian, Vice-Chairperson of the NPC Standing Committee and President of the ACWF, visited the hospital to see the new coming citizen. Zhang Weiqing, director of National Population and Family Planning Commission (NPFPC) of China, awarded him the certificate and gifts.

China mainland would reach 1,299,880,000 by the end of 2004, with a daily net increase of 20,800 on average. Based on this statistics, on January 6, this population would top at 1. 3 billion. NPFPC had determined in advance that the first baby born in this hospital after midnight would be the symbolic 1.3 billionth Chinese.

On the same day, more than 20,000 other babies were added to China’s population list.

The nation’s population policy over the past 25 years has contributed to balanced development, delaying the date of the landmark figure by four years.

B. he was the first baby China had on January 6,2005

D. he was the healthiest of all born on the same day

2. The baby’s birth is worth so much attention because ________.

A. 1.3 billion is a landmark figure in China’s population statistics

B. 1.3 billion is a turning point in China’s population growth

C. the birth symbolizes China’s success in family planning

D. the birth makes China’s population large enough for celebration

3. Which statement is correct according to the statistical data?

B. China’s population reached 1.3 billion by the end of January 5.

阅读材料,回答问题。

材料一:国家杜马(1906—1917年)是俄国的议会式全国代表机构。二十世纪初期,由于俄国资本主义的发展,资产阶级经济和政治力量的加强,特别是1905年革命的强大压力,迫使沙皇召开立法性国家杜马。沙皇政府企图借助国家杜马,拉拢资产阶级,扩大统治基础,消弭革命。以下是沙皇政府有关国家杜马法令的摘录:

1906年沙皇颁布的《国家杜马章程}规定:“杜马的代表由帝国居民选举产生,拥有立法权、财政预算审批权、质询权”。但同时又规定“皇帝有权在杜马任期结束前将其解散(实际上沙皇多次使用这项权力解散杜马)”,“杜马通过的决议若皇帝不予批准,则本次年会期间不得再次提交立法审议”。在颁布《国家杜马章程》同时,沙皇还颁布了《国务会议章程》,规定由沙皇任命贵族地主居多数的国务会议拥有与杜马同等的立法权,国务会议实际上成为议会上院。

1906年沙皇政府又颁布了《国家杜马选举法》。该法标榜“帝国居民不分阶级、财产、出身,均享有选举权”。同时又规定:土地所有者(贵族地主)每2千人产生一名议员候选人,而企业主(资产阶级)、农民、工人则分别由7千人、3万人、9万人中产生一名议员候选人,即土地所有者的一票相当于企业主的3票,农民的15票,工人的45票。

材料二:二战后,法兰西第四共和国成立。在制宪时期,戴高乐主张权力制衡,构建一种全新的共和政体——设立拥有实权的总统、加强内阁职权。但不为传统党派人士所采纳,新宪法对立法和行 * * 地位的调整朝着与戴高乐意愿相反的方向发展。……在中央各机构的设置中,国民议会被提到前所未有的高度,政府沦为其附属物,总统的权力更是被进一步架空。由于政党多元零散的状况没有得到改变,加上立法选举采取比例代表制的原因,议会内部党派结构较之前更为复杂。因此,形成稳定多数派的难度也加大了,行政机构的更迭更加频繁,政策也更加软弱无力。目睹多党机制再度过度运作,戴高乐黯然离开政坛。第四共和国宪法确立的政体仅运行了12年。1958年,在面对阿尔及利亚危机时此政体依旧没能克服其行政软弱,议会涣散的弊端。依赖强者的政治传统再次发挥作用,戴高乐在危急关头被推举为 * * ,并由国会赋予其制宪权。新宪法确立了倚重行政的机构设置,戴高乐在阔别政坛12年后终得依照自己的意愿重构共和政体。第五共和国宪法确立了拥有相当实权的总统、脱离议会产生的内阁及被规范化的议会。此外,戴高乐还变更了选举制度。法国依靠新宪法确立的政治体制,顺利解决了阿尔及利亚问题,克服了议会内部党派繁多涣散的弊病,行政机构的稳定和高效也得以彰显。
