男性與女性的差異問題在歷年考研英語真題閱讀中出現(xiàn)過幾次,是考生需要了解的重點(diǎn)話題。今天我們回顧一下2000年的考研英語閱讀真題,再次了解一下性別差異問題的相關(guān)信息。一起來看一下具體內(nèi)容:
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, by 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 the 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 variation is due to genes one more agent of evolution has gone.
嬰兒出生的男女性別比例約為105:100,這對(duì)男性而言是極其危險(xiǎn)的,因?yàn)榈搅顺赡觌A段,這個(gè)數(shù)字差異反而會(huì)縮小,到了70歲的時(shí)候男性僅剩下女性的一半。現(xiàn)在男性死亡率偏高的情形正在發(fā)生變化,男孩存活率幾乎同女嬰一樣高。這就意味著男孩到了尋找伴侶的關(guān)鍵年齡將首次出現(xiàn)男孩過,F(xiàn)象。更重要的是,又一次自然選擇的機(jī)會(huì)不復(fù)存在了。50年前,嬰兒(尤其是男嬰)存活的機(jī)會(huì)取決于體重,過輕或過重幾乎意味著必死無疑。今日體重幾乎不起什么作用,因?yàn)榇蟛糠植町愂怯苫蛞鸬,又一個(gè)進(jìn)化的因素消失了。
There is another way to commit evolutionary suicide: stay alive, but have fewer children. Few people are as fertile as in the past. 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.
還有另外一種方式會(huì)造成進(jìn)化自殺,那就是減少生育孩子的數(shù)量。現(xiàn)代社會(huì)已經(jīng)很少有人會(huì)生過多的孩子。并且嬰兒的出生率與死亡率也漸漸趨同,大多數(shù)人的后代數(shù)量基本相同。人們之間的差異以及利用這種差異進(jìn)行自然選擇的機(jī)會(huì)進(jìn)一步減少了。印度就可以說明正在發(fā)生的一切。這個(gè)國(guó)家給大城市里的少數(shù)人提供財(cái)富,而給其余的各部落民族以貧困。今天這種極其顯著的平均化——每個(gè)人的生存機(jī)會(huì)和子女?dāng)?shù)量都相同——意味著與部落相比較,自然選擇在印度中、上層已經(jīng)失去了80%的效力。
在歷年真題當(dāng)中考研英語一2008年text 1,以及英語二2013年text 3都考到了性別差異與性別平等問題。所以建議2016考研的考生將此類話題文章再拿出來,做統(tǒng)一的復(fù)習(xí)回顧,這樣再次出現(xiàn)同類話題時(shí)就比較方便理解了。預(yù)祝2016考研考生金榜題名!
