1、成人本科英语-186 及答案解析(总分：99.00，做题时间：90 分钟)一、Part Reading Compr(总题数：0，分数：0.00)二、Passage 1(总题数：1，分数：10.00)The biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with the portable computer in business class. In the last 15 years, pilots have reported well over 100 inc

2、idents that could have been caused by electromagnetic interference. The source of this interference remains unconfirmed, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones.RTCA, an organization

3、which advises the aviation (航空) industry, has recommended that all airlines ban(禁止)such devices from being used during “critical“ stages of flight particularly take- off and landing. Some experts have gone further, calling for a total ban during all flights. (76) Currently, rules on using these devi

4、ces are left up to individual airlines. And although some airlines prohibit passengers from using such equipment during take- off and landing, most are reluctant to enforce a total ban, given that many passengers want to work during flights.The difficulty is predicting how electromagnetic riel& migh

5、t affect all aircrafts computers. (77)Experts know that portable devices emit radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory, they have no way of knowing whether the interf

6、erence might be dangerous or not.The fact that aircraft may be vulnerable(易受损的)to interference raises the risk that terrorists may use radio systems in order to damage navigation equipment. (78) As worrying, though, is the passenger who cant hear the instructions to turn off his radio because the mu

7、sics too loud. （分数：10.00）(1).The main idea of this passage is _.A. a new rule for all airlines B. the defects of electronic devicesC. a possible cause of aircraft crashes D. effective safety measures for air flight（分数：2.00）A.B.C.D.(2).What is said about the over 100 aircraft incidents in the past 15

8、 years?A. They may have been caused by the damage to the radio systems.B. They may have taken place during take- off and landing.C. They were proved to have been caused by the passengers portable computers.D. They were suspected to have resulted from electromagnetic interference.（分数：2.00）A.B.C.D.(3)

9、The reason why few airlines want to impose a total ban on their passengers using electronic devices is _.A. they dont believe there is such a danger as radio interferenceB. the harmful effect of electromagnetic interference is yet to be provedC. they have other effective safety measures to fall bac

10、k onD. most passengers refuse to take a plane which bans the use of radio and cassette players（分数：2.00）A.B.C.D.(4).Why is it difficult to predict the possible effects of electromagnetic fields on an airplanes computers?A. Because it remains a mystery what wavelengths are liable to be interfered with

11、B. Because it is extremely dangerous to conduct such research on an airplane.C. Because research scientists have not been able to produce the same effects in labs.D. Because experts lack adequate equipment to do such research.（分数：2.00）A.B.C.D.(5).It can be guessed from the passage that the author _

12、A. is in favor of prohibiting passengers use of electronic devices completelyB. regards it as unreasonable to exercise a total ban during flightC. hasnt formed his own opinion on this problemD. has overestimated the danger of electromagnetic interference（分数：2.00）A.B.C.D.三、Passage 2(总题数：1，分数：5.00)If

13、 you smokeparticularly cigarettesyou are far more likely than a nonsmoker to suffer or die from several major diseasesnotably lung cancer.One smoker in four dies prematurely (过早地) because of his smoking.

14、k run by a nonsmoker 113 years older.Cigarette smokingand to a lesser degree pipe and cigar smokingmay aggravate(使恶化) or be partly responsible for the development of a wide variety of other diseases ,which include cancers of the mouth and throat ,peptic ulcers (胃溃疡), and loss of teeth.(77) Women who

15、 smoke during pregnancy produce babies on average about 5 to 8 ounces lighter than those who dont.Take lung cancer for example:Britains lung cancer figures are the highest in the world, and rising. Ninety people die every day, 33, 000 in 1969. Almost all these deaths can attributed directly to tobac

16、co smoking. (78)The prospects of a cure for lung cancer are, at present, remote, and it is impossible to estimate when, if ever, someone will find one. You would be foolish to rely on someone finding a cure before you needed it.One man in eight who dies between the ages of 35 and 64 is kill ed by lu

17、ng cancer. The figures for women in this age group are lower, about 1 in 20. This is partly because women smoke less, and have not smoked as long.

21、ral major diseases.（分数：1.00）A.B.C.D.四、Passage 3(总题数：1，分数：10.00)For well over 2000 years the worlds great religions have taught the virtues of a trust-ing heart. Now there is another reason to merit the wisdom of the ages: scientific evidence indicates that those with trusting hearts will live longer

22、 healthier lives. As a result of the work published in the 1970s by two pioneering heart specialists, Meyer Friedman and Ray H. Rosenman, nearly every American is aware that blood Type A people are impatient, and easily moved to hostility (敌意) and anger. (79) Many have come to believe that Type As

23、are at a much higher risk of suffering heart attack or dying of heart disease than others. The driving force behind hostilityis a cynical mistrust of others. If we expect others to mistreat us, we are seldom disappointed. This generates anger and leads us to respond with hostility.(80) The most char

24、acteristic attitude of a cynic is being suspicious of the motives (动机) of people he doesnt know. Imagine you are waiting for an elevator and it stops two floors above for longer than usual.

25、r motives.Meanwhile, your cynical mistrust is leading to noticeable physical consequences. Your voice rises. The rate and depth of your breathing increases.
