阅读理解训练题（二十九）
（A）
Wind—even the slightest of winds can prevent frost (霜冻).That’s because wind is like a spoon in your cup of tea: it stirs （搅起）things down and brings down a lot of warm air that often floats just above housetops and trees .
It may seem strange , but ice itself sometimes can protect crops from frost . Some growers actually spray their crops with water on a freezing night . Water freezes quickly on plants and then a strange thing happens . As long as ice stays wet , it can’t get colder than 32°F, a temperaure many plants can stand . By continual spraying water on the ice , the growers keep it from going below 32 degrees even if the air is much colder . This may defeat frost and saves plants .
This strange kind of “ice blanket” works only on plants that are strong enough to stand the weight of frozen spray . This is used even to protect banana plants on some Central American farms .
56．If the ice became entirely frozen and dry , suppose what might happen .
A．The plants might be frozen to death . B．The plants might benefit from it .
C．It might save the plants . D．It might make the plants grow slowly .
57．Ice can save plants rather than destroy them on condition that they are .
A．sprayed regularly B．quickly frozen C．not strong enough D．used to frost
58．The best title would be .
A．Frost Saves crops B．Ice Battle C．Ice Can Be Nice D．Ice Is Good
59．In which of the following sentences “stand” has the same meaning as in the last paragraph ?
A．He could hardly stand . B．This house stands the test of time .
C．The train stood for an hour . D．He stands in terrible danger .
(B)
Build the highway and watch the town grow . At first a few shops appear and maybe a restaurant . Then a hotel opens . Eventually new houses are built . A village is born .
This is also how the virtual world has developed . Think of the Internet as the road carrying information between two computers . Think of the World Wide Web as the village . At first it is just a place on the virtual road where travelers meet . More travelers come bringing new kinds of information . New villages are started .
Every village has a founder . Tim Berners Lee is the man who wrote the software program that led to the foundation of the World Wide Web . How did he get the idea ? He tells us on his own website : “ One of the things computers were not able to do was store contacts from different sources . The dream behind the Web is of a common space in which we communicate by sharing information.”
Tim Berners Lee could have followed the Microsoft route by forming a company to sell the programs he invented . Or he could have joined an existing company . But in his view the Web is a language , not a product . Charging a fee for using his programs would have slowed the growth of the Web . And other companies would make similar products to compete . Instead of one World Wide Web there would be several smaller Webs . Each would use incompatible （不相容的）software . The Web is valuable because it uses a common computer language to reach people and share information . Competing Webs would lose this value .Imagine if somebody sent you a bill every time you spoke a word of English .
In 1994 Tim Berners Lee formed World Wide Web Consortium , or W3C. More than 200 leading companies and laboratories are represented by W3C. Together they make sure that everyone no matter what their equipment or software is can work equally on the Web .
“The Web can help people to understand the way that others live and love . It helps us understand the humanity of people ,” he says .
60．Which appeared first , the Web or the Internet ?
A．The Web . B．The Internet
C．They appeared at the same time . D．There is no clue in the passage .
61．What does the underlined part “ the virtual world” refer to ?
A．The computer system . B．Scientific research
C．All the information on the Web and the Internet .
D．People working on the Web and the Internet
62．What can be inferred from the sentence “Imagine if somebody sent you a bill every time you spoke a word of English ?
A．The information on the Web should be shared by all .
B．The Web is where all kinds of information are stored .
C．People can get all kinds of information on the Web .
D．People can communicate on the Web .
63．Which is the main idea of the passage ?
A．How Tim Berners Lee founded the World Wide Web .
B．The advantage of working on the World Wide Web .
C．Why Tim Berners Lee wanted to found the World Wide Web .
D．The building of World Wide Web is similar to the building of highways .

Take care about those who use the truth to deceive. When someone tells you something that is true , but leaves out important information that should be included , he can make a false impression . For example , someone might say, “I just won a hundred dollars on the lottery . It was great . I took that dollar ticket back to the store and turned it in for one hundred dollars !”
This guy is a winner , right ? Maybe , maybe not . We then discovered that he bought two hundred tickets , and only one was a winner .He is really a big loser ! He didn’t say anything that was false , but he intentionally left out important information . That’s called a half-truth . Half truths are not technically lies , but they are just as dishonest .
Untrustworthy candidates（候选人）in political campaigns often use this trick . Let’say that during Governor Smith’s last term , her state lost one million jobs and gained three million jobs . Then she seeks another term . One of her opponents (对手) runs and ad. saying , “During Governor Smith’s term , the state lost one million jobs !” That’s true . However ,an honest statement would have been , “During Governor Smith’s term, the state had a net gain of two million jobs .”
Advertisers will sometimes use half-truths . It’s against the law to make false statements so they try to mislead you with the truth . An ad might boast （吹嘘）, “Nine out of ten-doctors recommend Yucky Pills to cure nose pimples.” It fails to mention that they only asked ten doctors and nine of them work for the Yucky Corporation .
This kind of trick happens too often . It’s a sad fact of life: Lies are lies ,and sometimes the truth can lie as well .

A．All advertisements are lies . B．You can’t trust anyone who tells the truth .

(E)
A new study says one part of the human brain may become smaller as the result of a condition known as jet lag . Jet lag results from flying long distances in an airplane . People with jet lag may feel extremely tired for several days . They may also have problems thinking clearly and remembering .
Recently a researcher at the University of Bristol in Britain reported the findings of his jet lag study , which involved twenty young women who worked for international airlines . They had served passengers on airplanes for five years . These flight attendants flew across many countries and at least seven time zones . In the study , the flight attendants had different amounts of time to recover from jet lag . Half the women spent five days or fewer in their home areas between long flights . The other half spent more than fourteen days in their home areas .
The researcher took some saliva from the women’s mouths to measure levels of a hormone （荷尔蒙）that increases during stress（紧张）. He tested them to see if they could remember where black spots appeared on a computer screen . And he took pictures of their brains to measure the size of the brain’s temporal lobes （脑叶）.
It was found that the women who had less time between flights had smaller right temporal lobes . This area of the brain deals with recognizing and remembering what is seen . The same group performed worse and had slower reaction times on the visual memory test . And their saliva samples showed higher levels of stress hormones .
The researcher believes the brain needs at least ten days to recover after a long trip . He says airline workers told him their ability to remember got worse after working on planes for about four years . Other studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that controls memory .
Scientists say more tests are needed to study the effects of jet lag on the brain . They want to find out if too much jet lag could permanently （永久性的）affect memory .
72．According to the text , jet lag .
A．can cause difficulties in speaking B．can make people feel tired for a few weeks
C．can be only found in flight attendants
D．can be caused by flying over several time zones
73．It can be inferred from the text that .
A．the conclusion is refused by many scientists
B．scientists fear that this research is not done properly
C．every scientific conclusion needs the support from many tests
D．the women who were examined in the research were not healthy
74．From the result of the research we can see that .
A．the women who have longer rest at home show better memory
B．the women who fly in short time have smaller right temporal lobes
C．the women who have longer flights fail the memory test
D．the women who rest more than 14 days produce less hormones
75．What is the subject discussed in the text ?
A．The cause of jet lag . B．A story of a group of flight attendants .
C．The importance of having enough rest after flights .
D．A research about the effects of jet lag on the brain .
