中国考博辅导首选学校中国考博辅导首选学校 华东师范大学考博英语模拟试题及其解析华东师范大学考博英语模拟试题及其解析 Being a man has always been dangerous There are about 105 males born for every 100 females but this ratio drops to near balance at the age of maturity and among 70 year olds there are twice as many women as men But the great universal of male mortality is being changed Now boy babies survive almost as well as girls do This means that for the first time there will be an excess of boys in those crucial years when they are searching for a mate More important another chance for natural selection has been removed Fifty years ago the chance of a baby particularly a boy baby surviving depended on its weight A kilogram too light or too heavy meant almost certain death Today it makes almost no difference Since much of the Geng duo yuan xiao

genes one more agent of evolution has gone 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 have 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 中国考博辅导首选学校中国考博辅导首选学校 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 For us this means that evolution is over the biological Utopia has arrived Strangely it has involved little physical change No other species fills so many places in nature But in the past 100 000 years even the past 100 years our lives have been transformed but our bodies have not We did not evolve because machines and society did it for us Darwin had a phrase to describe those ignorant of evolution they look at an organic being as average looks at a ship as at something wholly beyond his comprehension No doubt we will remember a 20th century way of life beyond comprehension for its ugliness But however amazed our descendants may be at how far from Utopia we were they will look just like us 15 What used to be the danger in being a man according to the first paragraph A A lack of mates B A fierce competition C A lower survival rate D A defective gene 16 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 中国考博辅导首选学校中国考博辅导首选学校 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 17 The author argues that our bodies have stopped evolving because A life has been improved by technological advance B the number of female babies has been declining C our species has reached the highest stage of evolution D the difference between wealth and poverty is disappearing 18 Which of the following would be the best title for the passage A Sex Ration Changes in Human Evolution B Ways of Continuing Man s Evolution C The Evolutionary Future of Nature D Human Evolution Going Nowhere 名师解析 15 What used to be the danger in being a man according to the first paragraph 根据第一段 做男人以前有什么危险 A A lack of mates 缺少配偶 B A fierce competition 激烈竞争 C A lower survival rate 低存活率 D A defective gene 有缺陷的基因 答案 C 考点 事实细节题 中国考博辅导首选学校中国考博辅导首选学校 分析 文中第一段提到 做男人从来都充满危险 新生儿男女比例 大约是105 100 但到了成年 这一比例基本持平 而在70岁的老人中女性 是男性的两倍 但是男性死亡率高这种普遍情况正在改变 现在男婴存活率 同女婴的基本一样高 这说明男人的存活率相对是比较低的 16 What does the example of India illustrate 印度的例子证明了什么 A Wealthy people tend to have fewer children than poor people 富人往往孩子比穷人少 B Natural selection hardly works among the rich and the poor 自然选择在穷人和富人之间几乎不起作用 C The middle class population is 80 smaller than that of the tribes 中产阶级的人口比部落人口少80 D India is one of the countries with a very high birth rate 印度是出生率很高的国家之一 答案 B 考点 推断题 分析 使用事例来证明是常见的逻辑思维模式 既然有事例 我们 就需要看到它的论点是什么 本文中提到 进化意义上的自杀还有一种方 法 存活 但少生孩子 首先 现在几乎没有人像过去那样多育 除了在 一些宗教社区 几乎没有几名妇女会生15个孩子 表明了 当今出生的数量 同死亡年龄一样变得平均化 我们大多数人的子女数量大致相当 再一次 人与人之间的差异和利用差异进行自然选择的机会降低了 其次 印度证 明了这种情况 这个国家给大城市里的少数人提供财富 而给其余的各部落 中国考博辅导首选学校中国考博辅导首选学校 居民造成了贫困 今天这种每个人的生存机会和子女数量都相同的极其显著 的平均化意味着与部落相比 自然选择在印度社会中 上层人群中 已经失 去了80 的效力 是为了证明 人与人之间的差异和利用差异进行自然选择 的机会降低了 换言之 自然选择在穷人和富人之间几乎不起作用 答案应该是 B 选项 17 The author argues that our bodies have stopped evolving because 作者认为我们的身体已经停止进化 因为 A life has been improved by technological advance 技术进步改善了人的生活 B the number of female babies has been declining 女婴的数量一直在减少 C our species has reached the highest stage of evolution 我们人种已经到达进化最高阶段 D the difference between wealth and poverty is disappearing 贫富差距间的区别正在消失 答案 A 考点 逻辑关系题 分析 文中提到停止进化是在第三段第一句 对我们来说 这意味 着进化已经结束 第三段中指出 在过去的10万年 甚至过去的100 年中 我们的生活发生了变化 但我们的身体却没变 我们没有进化 因为 机器和社会替我们办了这一切 机器 代表的就是 技术 因此我们 可以判定 A 是正确答案 18 Which of the following would be the best title for the passage 中国考博辅导首选学校中国考博辅导首选学校 以下哪一个最合适做本文标题 A Sex Ration Changes in Human Evolution 人类进化中的性别比例 变化 B Ways of Continuing Man s Evolution 继续人类进化的方式 C The Evolutionary Future of Nature 自然进化的未来 D Human Evolution Going Nowhere 人类进化无路可走 答案 D 考点 文章主旨题 分析 文章中在第一段结尾提到 由于大部分差异是由基因引起的 又一个进化的因素消失了 第二段中说 再一次 人与人之间的差异和利 用差异进行自然选择的机会降低了 第三段提到 但我们的身体却没变 我们没有进化 因为机器和社会替我们办了这一切 这些都表明作者认为 进化机制已不再起作用 认为自然进化机制已不能再左右人口的出生率 在 总结全文的第三段时 作者直截了当地指出 进化已经结束 因此可以认为 人类的进化是无路可走的 另外三个选项都不全面或者不对题 难句解析 1 There are about 105 males born for every 100 females but this ratio
