答案

小题1:C

题目分析:

小题1:20世纪末,我国的人口数量约13亿;而我国的合理人口容量即最适宜的人口数量,约7亿;我国的环境人口容量即我国应控制的最多人口数量,16亿左右。故C项正确。

小题2:材料反映的7亿指指我国的最适宜人口数量,即是指按照合理的生活方式,保障健康的生活的水平,同时又不妨碍未来人口生活质量的前提下的最适宜的人口数量,故属于人口合理容量。而环境人口容量是指在一定的资源、科技水平条件下,一个国家或地区所能养活的最多人口数量。

点评:本题难度一般,基础性试题,学生只要掌握环境人口容量与人口合理容量的基本概念与区别,并能结合材料和我国的人口实际分析即可。

When European Union (EU) leaders took delivery of Europe’s first draft of a constitution at a summit in Greece last June, it was with almost universal praise.

There was wide agreement that the text could save the EU from paralysis once it expands from 15 to 25 members next year. It would give Europe a more stable leadership and greater clout on the world stage, said the chairman of the Convention which drafted the agreement, former French President Valery Giscard d’Estaing.

Such praise was too good to last. As the product of a unique 16-month public debate, the draft has become a battleground. Less than four months after it was delivered, the same leaders who accepted it opened the second round of talks on its content this week by trading veiled threats to block agreement or cut off funds if they don’t get their way.

The tone was polite, but unyielding. In a bland joint statement issued when the talks opened on October 4, the leaders stressed the constitution, "represents a vital step in the process aimed at making Europe more cohesive, more democratic and closer to its citizens. "Sharp differences remain, though, between member countries of the EU over voting rights, the size and composition of the executive European Commission, defense co-operation and the role of religion in the new constitution.

Italian Prime Minister Silvio Berlusconi’s hopes of wrapping up a deal on the constitution by Christmas seem far from being realized. While the six founding members of the EU--Germany, France, Italy, the Netherlands, Belgium and Luxembourg--plus Britain and Denmark, want as little change as possible to the draft, the 10 mainly central European countries due to join the 15-nation bloc next year want to alter the institution’s balance.

Such small states are afraid their views will be ignored under the constitution and are determined to defend the disproportionate voting rights they won at the 2000 Nice Summit. EU experts fear such sharp differences will create exactly the paralysis in the EU the Convention was established to avoid.

Which of the following issue might not be their source of argument()

A. Leader election

B. Religious belief

C. Military cooperation

D. Economic cooperation
