恩波课堂六级冲刺题

There is another way to commit evolutionary suicide: stay alive, but have fewer children. Few people are as fertile as in the past. Except in some religious communities, very few women has 15 children. Nowadays the number of births, like the age of death, has become average. Most of us have roughly the same number of offspring. Again, differences between people and the opportunity for natural selection to take advantage of it have diminished. India shows what is happening. The country offers wealth for a few in the great cities and poverty for the remaining tribal peoples. The grand mediocrity of today everyone being the same in survival and number of offspring means that natural selection has lost 80% of its power in upper-middle-class India compared to the tribes.

31. what does the example of India illustrate?

A) Wealthy people tend to have fewer children than poor people.

B) Natural selection hardly works among the rich and the poor.

C) The middle class population is 80% smaller than that of the tribes.

D) India is one of the countries with a very high birth rate.

大家侃侃应该选什么，我一开始毫不犹豫地选了一个答案，后来再看一遍文章的时候。发现值得推敲的地方。于是开始疑惑。大家一起来做做，并说明选择的理由句。也请丁老师或黄老师有空指点指点。

大家来说说啊！这可是恩波内部材料啊

我也选了B，但是后来想想，我只看的出对富人不起作用，但看不出对穷人不起作用。请指点

选 B   

Again, differences between people and the opportunity for natural selection to take advantage of it have diminished.

b，举例题观点看前面一句Again, differences between people and the opportunity for natural selection to take advantage of it have diminished.

然后后面

wealth对应rich ，poverty对应poor~~
