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 brains 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 a very long period of time it is likely that mans 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.1the passage mainly tells us that _.amans life will be different in the futurebfuture man will look quite different from uscman is growing taller and uglier as time passesdmans organs functions will be on the wane2what serves as the evidence that man is changing?aman has got stronger eyes now than he ever had.bmans hair is getting thinner and thinner.cmans arms and legs have become lighter and weaker.dman has been growing taller over the past 500 years.3the change in mans size of forehead is probably because _.ahe makes use only 20% of the brains capacitybhis brain has grown larger over the past centuriescthe other 80% of his brain will grow in due timedhe will use his brain more and more as time goes on4which of the following is true about a human being in the future?ahe is hairless because hair is no longer useful.bhe has smaller eyes and wears better glasses.chis fingers grow weaker because he doesnt have to make use of them.dhe thinks and feels in different ways.5it is implied that _.ahuman beings will become less attractive in the futurebless use of a bodily organ may lead to its degenerationchuman beings hope for a change in the future lifedfuture life is always predictable分词作状语的主要用法如下：1表示时间。(1)hearing the news，they immediately set off for shanghai.听到这个消息，他们立刻动身去了上海。(2)when leaving the airport，they waved again and again to us.当离开机场的时候，他们再三向我们挥手道别。2表示原因。being spring festival，the shops are crowded.由于是春节，商店熙熙攘攘。3表示伴随。he walked down the hill，singing softly to himself.他自己对自己轻轻地唱着歌下山了。4表示条件。(1)if traveling north，you must
