7、gest 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 incidents that could have been caused by electromagnetic interference. The source of this interference remain
8、s 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 which advises the aviation(航空) industry, has recommended that all airlines ban(禁止) such devices from being
9、 used during “critical“ stages of flight, particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently, rules on using these devices are left up to individual airlines. And although some airlines prohibit passengers from using such equipmen
10、t 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 fields might affect an aircrafts computers. Experts know that portable devices emit radiation which affects those waveleng
11、ths 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 interference might be dangerous or not.The fact that aircraft may be vulnerable(易受损的) to interference raises the risk that
12、 terrorists may use radio system in order to damage navigation equipment. As worrying, though, is the passenger who cant hear the instructions to turn off his radio because the musics too loud.11 The passage is mainly about_.（A）a new regulation for all airlines（B） the defects of electronic devices（C
13、） a possible cause of aircraft crashes（D）effective safety measures for air flight12 What is said about the over 100 aircraft incidents in the past 15 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 t
14、o have been caused by the passengers portable computers.（D）They were suspected to have resulted from electromagnetic interference.13 Few airlines want to impose a total ban on their passengers using electronic devices because_.（A）they dont believe there is such a danger as radio interference（B） the
15、harmful effect of electromagnetic interference is yet to be proved（C） most passengers refuse to take a plane which bans the use of radio and cassette players（D）they have other effective safety measures to fall back on14 Why is it difficult to predict the possible effects of electromagnetic fields on
16、 an airplanes computers? _.（A）Because it is extremely dangerous to conduct such research on an airplane.（B） Because it remains a mystery what wavelengths are liable to be interfered with.（C） Because research scientists have not been to produce the same effects in labs.（D）Because experts lack adequat
17、e equipment to do such research.15 It can be inferred from the passage that the author_.（A）is in favor of prohibiting passengers use of electronic devices completely（B） has overestimated the danger of electromagnetic interference（C） hasnt formed his own opinion on this problem（D）regards it as unreas
18、onable to exercise a total ban during flight16 Many people believe the glare from snow causes snow blindness. Yet, dark glasses or not they find themselves suffering from headaches and watering eyes, and even snowblindness, when exposed to several hours of “snow light“.The United States Army has now
19、 determined that the glare from snow does not cause snow-blindness in troops in a snow-covered country. Rather, a mans eyes frequently find nothing to focus on in a broad expanse of a snow-covered area. So his gaze continually shifts and jumps back and forth over the entire landscape in search of so
20、mething to look at. Finding nothing, hour after hour, the eyes never stop searching and the eyeballs become sore and the eye muscle aches. Nature balances this annoyance by producing more and more liquid which covers the eyeballs. The liquid covers the eyeballs in increasing quantity until vision bl
21、urs. And the result is total, even though temporary, snowblindness.Experiments led the Army to a simple method of overcoming this problem. Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape. Ev
22、en the scouts themselves throw lightweight, dark-colored objects ahead on which they too can focus. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop searching through the snow-blanketed landscape. By focusing their a
23、ttention on one object at a time, the man can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a solid white area is overcome.16 The eyeballs become sore and the eye muscles ache because _.（A）tears cover the eyeballs（B） the eyes are annoyed by blindin
24、g sunlight（C） the eyes are annoyed by blinding snow（D）there is nothing to focus on17 When the eyes are sore, tears are produced to _.（A）clear the vision（B） remedy snowblindness（C） ease the annoyance（D）loosen the muscles18 Snow-blindness may be avoided by _.（A）concentration on the solid white area（B）
25、 providing the eyes with something to focus on（C） searching for something to look at in snow-covered areas（D）covering the eyeballs with liquid19 The flint paragraph is mainly concerned with（A）snow glare and snowblindness（B） the whiteness from snow（C） headaches, watering eyes and snowblindness（D）the
26、need for dark glasses20 A suitable title for this passage would be _.（A）Snowblindness and How to Overcome It（B） Natures Cure for Snowblindness（C） Soldiers in the Snow（D）Snow Vision21 Lead deposits, which accumulated in soil and snow during the 1960s and 70s, were primarily the result of leaded gasol
27、ine emissions originating in the United States. In the twenty years that the Clean Air Act has mandated unleaded gas use in the United States, the lead accumulation worldwide has decreased significantly.A study published recently in the journal Nature shows that air-borne leaded gas emissions from t
28、he United States were the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued research led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment at the National Center for Scientific Research in Franc
29、e. A study by Dr. Boutron published in 1991 showed that lead levels in arctic(北极的) snow were declining.In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline used in the United States were different from the ratios of European, Asian and Canadian gasolin
30、es and thus enabled scientists to differentiate(区分) the lead sources. The dominant lead ratio found in Greenland snow matched that found in gasoline from the United States.In a study published in the journal Ambio, scientists found that lead levels in soil in the Northeasten United States had decrea
31、sed markedly since the introduction of unleaded gasoline.Many scientists had believed that the lead would stay in soil and snow for a longer period.The authors of the Ambio study examined samples of the upper layers of soil taken from the same sites of30 forest floors in New England, New York and Pe
32、nnsylvania in 1980 and in 1990. The forest environment processed and redistributed the lead faster than the scientists had expeeted.Scientists say both studies demonstrate that certain parts of the ecosystem(生态系统) respond rapidly to reductions in atmospheric pollution, but that these findings should
33、 not be used as a license to pollute.21 The study published in the journal Nature indicates that _.（A）the Clean Air Act has not produced the desired results（B） lead deposits in arctic snow are on the increase（C） lead will stay in soil and snow longer than expected（D）the U.S. is the major source of l
34、ead pollution in arctic snow22 Lead accumulation worldwide decreased significantly after the use of unleaded gas in the U.S._.（A）was discouraged（B） was enforced by law（C） was prohibited by law（D）was introduced23 How did scientists discover the source of lead pollution in Greenland?（A）By analyzing th
35、e data published in journals like Nature.（B） By observing the lead accumulations in different parts of the arctic area.（C） By studying the chemical elements of soil and snow in Northeastern America.（D）By comparing the chemical compositions of leaded gasoline used in various countries.24 The authors
36、of the Ambio study have found that_.（A）forests get rid of lead pollution faster than expected（B） lead accumulations in forests are more difficult to deal with（C） lead deposits are widely distributed in the forests of the U.S.（D）the upper layers of soil in forests are easily polluted by lead emission
37、s25 It can be inferred from the last paragraph that scientists（A）are puzzled by the mystery of forest pollution（B） feel relieved by the use of unleaded gasoline（C） still consider lead pollution a problem（D）lack sufficient means to combat lead pollution26 Some psychologists maintain that mental acts
38、such as thinking are not performed in the brain alone, but that ones muscles also participate. It may be said that we think with our muscles in somewhat the same way that we listen to music with our bodies.You surely are not surprised to be told that you usually listen to music not only with your ea
39、rs but with your whole body. Few people can listen to music that is more or less familiar without moving their body or more specifically, some part of their body. Often when one listens to a symphonic concert on the radio, he is tempted to direct the orchestra even though he knows them is a competen
40、t conductor on the job.Strange as this behavior may be, there is a very good mason for it. One cannot derive all possible enjoyment from music unless he participates, so to speak, in its performance. The listener “feels“ himself into the music with more or less noticeable motions of his body.The mus
41、cles of the body actually participate in the mental process of thinking in the same way, but this participation is less obvious because it is less noticeable.26 Some psychologists maintain that thinking is _.（A）not a mental process（B） more of a physical process than a mental action（C） a process that
42、 involves our entire bodies（D）a process that involves the muscles as well as the brain27 Few people are able to listen to familiar music without _.（A）moving some part of their body（B） stopping what they are doing to listen（C） directing the orchestra playing it（D）wishing that they could conduct music
43、 properly28 Body movements are necessary in order for the listener to _.（A）hear the music（B） appreciate the music（C） enjoy the music fully（D）completely understand the music29 According to the selection, muscle participation in the process of thinking is _.（A）deliberate（B） obvious（C） not readily appa
44、rent（D）very pronounced30 The best title for this selection is _.（A）An Ear for Music（B） Music Appreciation（C） How Muscles Participate in Mental Acts（D）A Psychological Definition of the Thinking Process三、Part III ClozeDirections: There are ten blanks in the following passage.
