       Judging from recent surveys, most experts in sleep behavior agree that there is virtually an epidemic(流行病) of sleepiness in the nation.“I can’t think of a single study that hasn’t found Americans getting less sleep than they ought to,” says Dr.David.Even people who think they are sleeping enough would probably be better off with more rest.

       The beginning of our sleep-deficit(lack)crises can be traced back to the invention of the light bulb a century ago.From diary entries and our personal accounts from the 18th and 19th centuries, sleep scientists have reached the conclusion that the average person used to sleep about 9.5 hours a night.“The best sleep habits once were forced on us, when we had nothing to do in the evening down on the farm, and it was dark.” By the 1950s and 1960s, the sleep schedule had been reduced dramatically, to between 7.5 and 8 hours, and most people had to wake to an alarm clock.“People cheat in their sleep, and they don’t even realize they’re doing it,” says Dr.David.“They think they’re okay because they can get by on 6.5 hours, when they really need 7.5, 8 or even more to feel ideally energetic. ”

       Perhaps the most merciless robber of sleep, researches say, is the complexity of the day.Whenever pressures from work, family, friends and community increase, many people consider sleep the least expensive item on their programs.“In our society, you’re considered dynamic if you say you need only 5.5 hours’ sleep.If you’ve got to get 8.5 hours, people think you lack drive and ambition.”

       To determine the consequences of sleep-deficit, researchers have put subjects through a set of psychological and performance tests requiring them, for instance, to add columns of numbers or recall a passage read to them only minutes earlier.“We’ve found that if you’re in sleep deficit, performance suffers,” says Dr.David.“Short-term memory is weakened, as are abilities to make decisions and to concentrate.”

61.What is the main topic of the passage?

       A. The history of people’s sleeping patterns.

       B. The epidemic of sleepiness in the modern times.

       C. Research on the causes and consequences of sleep-deficit.

       D. The minimum of our sleeping hours.

62.Which of the following is Dr.David’s opinion?

       A. People’s metal power suffers if they are lacking in sleep.

       B. Some people can remain energetic with only 6.5 hours’ sleep a night.

       C. If they get 8.5 hours’ sleep, people will be full of drive and ambition.

       D. People who think they are sleeping enough are better off than those who don't.

63.People in the 18th and 19th centuries slept about 9.5 hours a night because _______.

       A. they had no electricity

       B. they knew what was best for their health

       C. they were forced by their parents to do so

       D. they were not so dynamic and ambitious as modern people are

64.The major cause of sleep-deficit of modern people is _______.

       A. the endless TV programs in the evenings and the internet

       B. the heavy work load of the day

       C. the sufficient energy modern people usually have

       D. loud noises in the modern cities

65.What does the word “subjects” in paragraph 4 mean?

       A. Person or thing that is being discussed or described.

       B. Branch of knowledge studied in a school.

       C. Person or thing being treated in a certain way or being experimented on.

       D. Any member of a State apart from the supreme ruler.

Today, when there are many top graduates looking for top jobs, graduates can differentiate(區(qū)別) themselves by obtaining a double major or even a double degree. Increasingly, employers are looking for individuals who are not only competent and intelligent, but who have different skill sets and who are knowledgeable in many areas. Part of the appeal to employers is that your extra work demonstrates a willingness to take on difficult tasks. Additionally, if your majors overlap (重疊), you are able to show potential employers that you have both breadth and depth of knowledge.

By studying for a double major, although you will be studying for only one degree, you will be focusing on two related and integrated subjects that complement (補(bǔ)充) each other. Classes overlap between the majors, meaning fewer classes are required than with a double degree, so it is easier to finish within four years.

In contrast, with the more rigorous (嚴(yán)格的) double degree, you will be studying for two different degrees in two completely different areas of study. Although pursuing such a course  of study allows students to complete two wholly separate degrees in less time than if they were to earn them separately, many strong students still find it incredibly difficult to complete in four or five years.

If you are committed to a double major/degree, it is wise to do a little bit of planning. Some students try to find two courses of studies that are related, while others seek to round out their academic studies by choosing two completely unrelated fields.

  For double majors, common pairings include: (i) economics and a foreign language; (ii) political science or government and journalism; (iii) economics and psychology.

For double degrees, common pairings include: (i) engineering and a business program such as finance or accounting; (ii) engineering and economics.

56. What do employers think of the graduates with different skill sets and knowledge in many areas?

A. They should be given top jobs.              

  B. They are willing to take difficult tasks.

  C. They are better than those who are competent and intelligent.

  D. They must have attained a double major or even a double degree.     

57. According to the passage, the underlined word “breadth” most probably means_________.

   A. quality         B. amount       C. quantity     D. width

58. To obtain a double major, you _________.

   A. should complete two wholly separate degrees

   B. need to focus on two related and integrated subjects

   C. need to spend more time than obtaining a double degree

   D. have to take courses in two completely different areas of study

59. If you are devoted to a double major or degree, you should _________.

A. find two subjects with overlapping classes

   B. learn about what your potential employers want

   C. decide what to learn with your intentions considered

   D. try to decide on some common pairings as soon as possible

60. Which statement is CORRECT according to the passage?

A. Economics is a major while engineering is a degree.

   B. Every college student should take a double major or degree.

   C. Earning a double degree is more difficult than obtaining a double major.
