2017年职称英语考试理工类(C级)试题,
2．Hurricanes and typhoons(台风)are the same things．If they form in the Atlantic，we call these strong storms hurricanes，from the West Indian word hurricane，meaning"big wind．"And if they are Pacific storms，they are called typhoons from the Chinese taifun，meaning"great wind．"To be classified as a hurricane，the storm must have maximum winds of at least 75 mph.These storms are big，many hundreds of miles in diameter．
3．Hurricanes get their power from water vapor as it gwes out its stored'up energy．All water vapor gives out heat as it condenses(凝结)from a gaseous state to a liquid state over fixed points on the equator(赤道)．To make a hurricane，you must have extremely wet，warm all the kind of air that can only be found in tropical regions．
4． Scientists have determined that the heat given out in the process of water condensation can be as high as 95 billion kilowatts per hour．In just one day alone，the storm can produce more energy than many industrialized nations need in an entire year!The problem is that we don't know how to make such great energy work for us．
5．Predicting the path of a hurricane is one of the most difficult tasks for forecasters．It moves at a typical speed of l5 mph．But not always．Some storms may race along at twice this speed， then suddenly stop and remain in the same location in the ocean for several days．It can be maddening(发疯的)if you live in a coastal area that may be hit．
6．The biggest advance in early detection is continuous watch from weather satellites．With these，we can see the storms form and track them fully,from birth to death．While they can still
kill people and destroy property,hurricanes will never surprise any natron again.

第4部分：阅读理解(第31~45题，每题3分，共45分)
下面有3篇短文，每篇短文后有5道题，每题后面有4个选项。请仔细阅读短文并根据短文回答其后面的问题，从4个选项中选择1个最佳答案涂在答题卡相应的位置上。
第一篇 Mobile Phones
Mobile phones should carry a label if they proved to be a dangerous source of Fadiation．according to Robert Bell，a scientist．And no more mobile phone transmitter towers(发射塔)
should be built until the long．term health effects of the electromagnetic radiation they emit(放射)is scientifically evaluated．he said．"Nobody's going to drop dead overnight but we should be asking for more scientitic information．"Robert Bell said at a conference on the health effecfs of low-1evel radiation．"If mobile phones are found to be dangerous．they should carry a warning label until proper shields can be devised．"he said．
A report widely circulated(传播)among the public says that up to now scientists do not really know enough to guarantee there are no ill effects on humans from electromagnetic radiation．According to Robert Bell，there are 3.3 million mobile phones in Australia alone and they are increasing by 2，000 a day．By the year 2000 it is estimated that Australia will have 8
million mobile phones：nearly one for every two people．
As well，there are 2，000 transmitter towers around Australia，many in high density(密度) residential areas．For example,Telstra，Optus and Vodaphone build their towers where it is geographically suitable to them and disregard the need of the community．The electromagnetic radiation emitted from these towers may have already produced some harmful effccts on the health of the residents nearby．
Robert Bell suggests that until more research is completed the Govemment should ban construction of phone towers from within a 500 meter radius (半径)of school grounds，child care
centers，hospitals，sports playing fields and residential areas with a high percentage of children．He says there is emerging evidence that children absorb low．1evel radiation at a rate more than three times that of adults．He adds that there is also evidence that if cancer sufierers are subjected to electromagnetic waves the growth rate of the disease accelerates(提高)．
Robert Bell calls on the major telephone companies to fund adequate research and urges(敦促)the Government to set up a wide ranging inquiry into possible health effects．
31 According to Robert Bell，if mobile phones prove to be dangerous to people's health，
A they should be banned immediately．
B the use of them should be restricted．
C all transmitter towers should be torn down．
D a warning label should be attached．
32 How many mobile phone users will there be in Australia by the year 2000，according to the passage?
A 3.3 million．
B Almost half of the population．
C One third of the population．
D One fourth of the population．
33 Many transmitter towers were built
A on high mountains．
B in places suitable to the phone users.
C in areas which can take in radiation．
D in densely populated areas．
34 Who absorb low-1evel radiation at a higher rate than the others?
A Children．
B Men．
C Women．
D Old people．
35 This article mainly argues that
A the Goverdnment should restrict the number of mobile phone users.
B mobile phones may have ill effects on people.
C mobile phones have proved to be harmless to people's health.
D no more phone towers should be constructed.
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．
