11．What will man be like in the future-in 5000or even 50，000years 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 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．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 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 this gives the impression that 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．

32．Which of the following serves as the evidence that man is changing？C
A．Man's hair is getting thinner and thinner．
B．Man has got stronger eyes now than he ever had．
C．Man has been growing taller over the past 500years．
D．Man's arms and legs have become lighter and weaker．
33．Which of the following is TRUE about a human being in the future？C
A．He thinks and feels in a different way．
B．He has smaller eyes and wears better glasses．
C．He is hairless because hair is no longer useful．
D．His fingers grow weaker because he doesn't use them．
34．The passage mainly tells us thatB．
A．man's life will be different in the future
B．future man will look quite different from us
C．man is growing taller and uglier as time passes
D．Man's organs'functions will change
35．It is implied thatB
A．human beings will become less attractive in the future
B．body organs will become poorer if they are not used often
C．human beings hope for a change in the future life
D．future life is always predictable．

分析 本文是一篇科幻類短文，是關(guān)于將來的人類將變成什么樣子，如果我們對某項技能使用較多，那么我們就可能會進一步發(fā)展該項．如果我們不使用，那么某項技能就有可能退化．

解答 32．C  細節(jié)理解題，根據(jù)第二段Man，even five hundred years ago，was shorter than he is today．Now，on average，men are about three inches taller可知作者以過去500年來人類慢慢變高為例說明人類是不斷變化的，故選C．
33．C  細節(jié)理解題，根據(jù)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．可知未來頭發(fā)將不起任何作用，男人和女人都可能是禿頂?shù)�，故選C．
34．B  主旨大意題．根據(jù)主題段第一段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．說明本文是講述將來的人會與現(xiàn)在的人有很大的差別，故B正確．
35．B  推理判斷題．本文所舉的多個例子都說明我們的身上的變化都是因為不使用而發(fā)生的退化，如我們的頭發(fā)，我們的四肢，故選B．

點評 考查學生的細節(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，再做出正確選擇．在做推理判斷題時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．

2．Scientists say California's special landscapes （地貌） are changing gradually as the world gets warmer．Now，with a new generation of computer models，they're trying to make clear what those changes will be：Less snow？More wildfires？Fewer animals？
The new computer models allow scientists to divide the state into much smaller regions than ever before---just thirty-six square miles．These regional models give scientists a way of draping （覆蓋） climate over California's complex landscape．
Scientists want to understand how warming will affect the state's people，its economy，and the thousands of species that only live in California．The State's Climate Action Team has organized a meeting last month in Los Angeles on the economic effects of these targets．
California started the only state-run climate research program three years ago and is spending about $5 million a year on it．The goal of the research is to limit the impact of such changes．
California is part of an internationally recognized"hot spot"of biodiversity （生物多樣性） that e xtends north across the Oregon border and south into Baja California．It's home to 4，426 species of plants，nearly half of which are found nowhere else．
What happens in California could have great influence．If California were a nation，it would be the fifth-biggest economy in the world and the 12th-biggest producer of greenhouse gases．
28．The writer intends to tell readersD．
A．studies on the future wildlife in California by computer
B．research on the economy of California caused by getting warmer
