8.What will man be like in the future-in 5,000 or even 50,000 years from now?We can only make guesses,of course,but we can be sure that he will be different from what he is today,for man is slowly changing all the time.
Let us take an obvious example.Man,even five hundred years ago,was shorter than he is today.Now,on average,men are about three inches taller.Five hundred years is relatively a short period of time,so we may assume that man will continue to grow taller.Again,in the modern world we use our brains a great deal.Even so,we still make use of only about 20% of the brain's capacity(容量).As time goes on,however,we shall have to use our brains more and more,and eventually we shall need larger ones!This is likely to bring about a physical change to the head,in particular,the forehead will grow larger.
Nowadays our eyes are in constant use.In fact,we use them so much that very often they become weaker and we have to wear glasses.But over a very long period of time it is likely that man's eyes will grow stronger.
On the other hand,we tend to make less use of our arms and legs.These,as a result,are likely to grow weaker.At the same time,however,our fingers will grow more sensitive because they are used a great deal in modern life.
But what about hair?This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer.In the future,then,both sexes are likely to be bald.
Perhaps all these give the impression that in the future man will not be a very attractive creature to look at!This may well be true.All the same,in spite of all these changes,future man will still have a lot in common with us.He will still be a human being,with thoughts and emotions similar to our own.

分析 本文屬于說明文閱讀,作者通過這篇文章主要向我們描述了未來人類的外貌,推測未來的人看起來與我們會完全不同.
解答 32.A.主旨大意題.本文主要介紹未來人類的外貌,可知這篇文章主要告訴我們未來的人看起來與我們會完全不同;故選A.
33.B.細節(jié)理解題.由第二段第二句"Man,even five hundred years ago,was shorter than he is today"可知.在過去的500年里一直長高是人類變化的證據(jù);故選B.
34.C.推理判斷題.由倒數(shù)第二段"But what about hair?This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer."可知,人類的頭發(fā)最終可能會消失,因為頭發(fā)失去了作用.故選C.
34.D.推理判斷題.從人類身體變化可以看出,經(jīng)常使用的器官部位,如大腦、手指將變得發(fā)達.而不常用的器官會退化;故選D.
點評 考察學(xué)生的細節(jié)理解和推理判斷能力,做細節(jié)理解題時一定要找到文章中的原句,和題干進行比較,再做出正確的選擇.在做推理判斷題不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進行合乎邏輯的推理判斷.
