第二篇 A Thirsty World
　　The world is not only hungry，it is also thirsty for water．This may seem strange to you，since nearly 75％of the earth's surface is covered with water．But about 97％of this huge amount is sea-water，or salt water．Man can only drink and use the other 3％-the flesh water that comes from rivers，lakes，underground，and other sources． And we cannot even use all of that，because some of it is in the form of icebergs(冰山)and glaciers(冰川)．Even worse，some of it has been polluted．
　　At the moment，this small amount of fresh water is still enough for us．However,our need for water is increasing rapidly．Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on．A limited water supply would have a bad effect on agriculture and industry．
　　In addition to stopping wasting our precious water,one useful step we should take is to develop ways of reusing it．Experiments have already been done in this field，but only on a small scale.
　　Today,in most large cities，water is used only once and it eventually returns to the sea or runs into underground storage tanks．But it is possible to pipe water that has been used to a purifying(净化)plant．There it can be filtered(过滤)and treated with chemicals so that it can be used againjust as if it were flesh from a spring．
　　But even if every large city purified and reused its water,we still would not have enough.Where could we turn next?To the oceans!A11 we'd have to do to make use of the vast amount of
　　sea-water is-remove the salt．This salt-removing process is already m use in many parts of the world．
　　So if we take all these steps，we'll be in no danger of drying up !
　　36 The phrase''the world"in the first line of the passage refers to
　　A "man"．
　　B "you"．
　　C "woman".
　　D "they"．
　　37 What percentage of the earth's water can man actually use at present?
