1、专业英语四级(阅读)模拟试卷 143及答案与解析 一、 SECTION A In this section there are several passages followed by ten multiple-choice questions. For each question, there are four suggested answers marked A, B, C and D. Choose the one that you think is the best answer. 0 (1)The regular use of text messages and e-mails ca
2、n lower the IQ more than twice as much as smoking marijuana. That is the claim of psychologists who have found that tapping away on a mobile phone or computer keypad or checking them for electronic messages temporarily knocks up to 10 points off the users IQ. (2)This rate of decline in intelligence
3、compares unfavorably with the four-point drop in IQ associated with smoking marijuana, according to British researchers, who have labeled the fleeting phenomenon of enhanced stupidity as “infomania“. (3)Research on sleep deprivation suggests that the IQ drop caused by electronic obsession is also eq
4、uivalent to a wakeful night. (4)Infomania is mainly a problem for adult workers, especially men, the study commissioned by Hewlett Packard, the technology company, has concluded. (5)The noticeable drop in IQ is attributed to the constant distraction of “always on“ technology when employees should be
5、 concentrating on what they are paid to do. Infomania means that they lose concentration as their minds remain fixed in an almost permanent state of readiness to react to technology instead of focusing on the task in hand. (6)The brain also finds it hard to cope with juggling lots of tasks at once,
6、reducing its overall effectiveness, the report added. And while modern technology can have huge benefits, excessive use can be damaging not only to a persons mind, but to their social life. (7)Eighty volunteers took part in clinical trials on IQ deterioration and 1,100 adults were interviewed. More
7、than six in ten(62 per cent)of people polled admit that they were addicted to checking their e-mails and text messages so often that they scrutinized work-related ones even when at home or on holiday. Half said that they always responded immediately to an email and one in five(21 per cent)will inter
8、rupt a meeting to do so. (8)Furthermore, infomania is having a negative effect on work colleagues, increasing stress and dissenting feelings. Nine out of ten polled thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude. Yet one in three Britons be
9、lieves that it is not only acceptable, but actually diligent and efficient to do so. 1 To initiate the study, Hewlett Packards research is most probably about _. ( A) the relevance between ones IQ and his use of technology ( B) the influence of technology on ones decline in intelligence ( C) the dif
10、ferent damage to our brain done by technology and unhealthy habits ( D) the relationship between ones intelligence and his working effectiveness 2 Infomania employees are more ready to react to technology than the tasks in hand because _. ( A) the tasks cant be done without technology ( B) technolog
11、y is conveniently available ( C) the tasks are technologically diverse ( D) technology can help lessen work pressure 2 (1)Moderate drinking reduces stroke risk, study confirms. Similar to the way a drink or two a day protects against heart attacks, moderate alcohol consumption wards off strokes, a n
12、ew study found. (2)The study also found that the type of alcohol consumed beer, wine or liquor was unimportant. Any of them, or a combination, was protective, researchers reported in the Journal of the American Medical Association recently. “No study has shown benefit in recommending alcohol consump
13、tion to those who do not drink“, cautioned the authors, led by Dr. Ralph L. Sacco of Columbia University College of Physicians and Surgeons in New York. But the hew data support the guidelines of the National Stroke Association, which say moderate drinkers may protect themselves from strokes by cont
14、inuing to consume alcohol, the authors said. (3)The protective effect of moderate drinking against heart attacks is well established, but the data has been conflicting about alcohol and strokes, the authors said. The new study helps settle the question and is the first to find blacks and Hispanics b
15、enefit as well as whites, according to the authors. Further research is needed among other groups, such as Asians, whose past studies suggest they may get no stroke protection from alcohol or may even be put at great risk. (4)Among groups where the protective effect exists, its mechanism appears to
16、differ from the protective effect against heart attacks, which occurs through boosts in levels of so-called “good“ cholesterol, the authors said. They speculated alcohol may protect against stroke by acting on some other blood trait, such as the tendency of blood platelets to accumulate, which is ke
17、y in forming the blood clots that can cause strokes. (5)The researchers studied 677 New York residents who lived in the northern part of Manhattan and had strokes between July 1, 1993 and July 1, 1997. After taking into account differences in other factors that could affect stroke risk, such as high
18、 blood pressure, the researchers estimated that subjects who consumed up to two alcoholic drinks daily were only half as likely to have suffered clot-type strokes as nondrinkers. Clot-type strokes account for 80 percent of all strokes, a leading cause of US deaths and disability. Stroke risk increas
19、ed with heavier drinking. At seven drinks per day, risk was almost triple that of moderate drinkers. 3 The principle of protecting oneself from strokes by consuming alcohol reasonably cannot be applied to _. ( A) heavy drinkers ( B) light drinkers ( C) mild drinkers ( D) non-drinkers 4 How does mode
20、rate alcohol consumption most probably protect us from strokes? ( A) By enhancing the level of the good cholesterol. ( B) By reducing the possibility of the blood platelets to deposit. ( C) By reducing the number of blood platelets and blood clots. ( D) By enhancing the quality of overall blood trai
21、ts. 4 (1)For any surfer, nothing beats the idea of just hanging out in a beach riding the waves all day. The thrill of riding giant breaks and staying there a minute or two is enough to thrill any surfer. Some surfers save money just to go to certain locations around the world to experience the wave
22、s they will cherish their whole life. Read on and well tell you where to go and whats the best place in the world to surf ever. (2)Lets start with the simplest. Cocoa Beach in Florida is one of the key surfing destinations in US. However, dont go there during summer as the waves could be unpredictab
23、le, and most of the time youll just end up sitting there for nothing at all. The good thing about this beach is that you can still enjoy the waters and the party mood especially in summer time. The best time to go this beach for surfing is from November to March, thats right: winter season. During t
24、hese months the Atlantic winds becomes stronger and the water responds perfectly! Expect to have waves that will reach up to 10 feet. The beach is perfect for beginners in the sport. (3)Of course we dont want to leave out the state that started it all: Hawaii. Specifically Oahu, Hawaii; which is the
