  In what now seems like the prehistoric times of computer history,the earth's postwar era,there was quite a wide-spread concern that computers would take over the world from man one day. Already today,less than forty years later,as computers are relieving us of more and more of the routine tasks in business and in our personal lives,we are faced with a less dramatic but also less foreseen problem.People tend to be over-trusting of computers and are reluctant to challenge their authority.Indeed,they behave as if they were hardly aware that wrong buttons may be pushed,or that a computer may simply malfunction(失误).

  Obviously,there would be no point in investing in a computer if you had to check all its answers,but people should also rely on their own internal computers and check the ma-chine when they have the feeling that something has gone wrong.

  Questioning and routine double-checks must continue to be as much a part of good

business as they were in pre-computer days.Maybe each computer may provide,it should

not be seen as a substitute for fundamental thinking and reasoning skills.

1.What is the main purpose of this passage?

[  ]

A.To look back to the early days of this passage.

B.To explain what technical problems may occur with computers.

C.To discourage unnecessary investment in computers.

D.To warn against a mentally lazy attitude towards computers.

2.According to the passages,the initial concern about computer was that they might

[  ]

A.change our personal lives

B.take control the world

It's safe, it's simple, and it works: Drinking right amounts of water really can help you lose weight, new research shows.

   In what researchers claim is the first-ever trial of the effect of water consumption on weight loss, scientists from Virginia Tech found that dieters who started each meal with two glasses of water lost nearly five pounds more, on average, than dieters who did not, over the course of 12 weeks. There's no shortage of clear evidence about how water might work to control your appetite (食欲). It ________________ so you don't eat so much; it keeps down your thirst so that you don't turn to calorie-rich sodas or juices. But until now, the researchers say, there has been no true evidence that water's appetite-controlling benefits ever translate into actual weight loss. Now there is. In the 12-week study period, dieters instructed to drink water with every meal lost an average of 15.5 pounds; dieters given no instructions lost, on average, just 11 pounds.

  Perhaps the most surprising thing about the finding is how little we still know about healthy water consumption in general. In fact, although doctors and public health authorities regularly remind us to drink more water, very few studies give any insight into what our ideal quantity may be.

  The new results today suggest that many people could indeed stand to drink a little more water than they do. But if you're looking to lose weight, be aware that it is actually possible to drink too much water, and you probably won't help matters any by drinking too much water at a time. In extreme cases, it can even be deadly. A couple of glasses with each meal, however, should be no problem at all for a healthy person.

  1.What is the main idea of the text?(no more than 8 words)

  ____________________________________________________________________

  2.Complete the following statement with proper words.(no more than 2 words)

   Enough obvious evidence ________________ how your appetite might be under the control of water.

  3.Fill in the blank in Paragraph 2 with proper words.(no more than 3 words)

  ____________________________________________________________________

  4.Why should we avoid drinking too much water at a time?(no more than 6 words)

  _____________________________________________________________________

  5.What does the word "it" (Line 1, Paragraph 1) probably refer to?(no more than 6 words)

  _____________________________________________________________________

  Habitual, long-term mobile phone users could soon know if they are at risk of developing cancer.

  In what is believed to be a world-first study, human brain cells are being used to test the long-term effects of mobile phone radiation.

  The study will use a device to simulate (模拟) the effect of longtime exposure(暴露) of the brain to electromagnetic radiation from mobile over a long period.

  Testing will be done by researchers at Sydney's St. Vincent's Hospital . The project's chief investigator(调查者) , Peter, a French researcher, said the trial would test whether mobile phone radiation causes cancer in long-term users.

  Testing will either prove people's fear, or show that there is no effect on human brain cells or perhaps that cells can become immune(免疫的) to electromagnetic radiation through repeated exposure.

  During the study, brain cells will be exposed to electromagnetic radiation for an hour each day. Test results are expected in three to six months, with the final report to be published by the end of the year.

  The research is unique because most previous studies have focused on short-term exposure on animal cells, which did help understand the effects of years of regular mobile phone use on human brain cells.

  As mobile phones become increasingly popular throughout our society, it is important that we understand as much as possible about the long-term effect of electromagnetic exposure, if any, on human health.

1.According to the text, what might cause mobile phone users to suffer from a deadly disease is ________.

[  ]

A.that there is same poison in mobile phones

B.mobile phone on

C.the polluted plastic covers of the mobile phones

D.sate parts of the mobile phones

2.Who will do such a test?

[  ]

A.A French doctor.

B.An American dolor.

C.A Japanese scientist.

D.An English scientist.

3.Which of the following statements is true according to the passage?

[  ]

A.The testing is dangerous to people's safety.

B.Such a research is the first of the kind in the world.

C.People feel afraid when they hear of doing such a teat.

D.The teat result will be published in three or six days.

4.The test is carried out mainly to ________.

[  ]

A.find out how to use nubile phones safely

B.find out how to protect mobile phones carefully

C.warn people of possible harm if they use mobile phones for a long time

D.tell people that some scientists will do a test about long-term mobile phone uses and their health
