1、四级阅读练习四级阅读 之 “大意篇”Passage OneQuestions 21 to 25 are based on the following passage.Oceanography has been defined as “The application of all sciences to the study of the sea”.Before the nineteen century, scientists with an interest in the sea were few and far between. Certainly Newton considered some
2、 theoretical aspects of it in his writings, but he was reluctant to go to sea to further his work.For most people the sea was remote, and with the exception of early intercontinental travelers or others who earned a living from the sea, there was little reason to ask many questions about it, let alo
3、ne to ask what lay beneath the surface. The first time that question “What is at the bottom of the oceans?” had to be answered with any commercial consequence was when the laying of a telegraph cable from Europe to America was proposed. The engineers had to know the depth profile (起伏形状) of the route
4、 to estimate the length of cable that had to be manufactured.It was to Maury of the US Navy that the Atlantic Telegraph Company turned, in 1853, for information on this matter. In the 1840s, Maury had been responsible for encouraging voyages during which soundings (测声) were taken to investigate the
5、depths of the North Atlantic and Pacific Oceans. Later, some of his findings aroused much popular interest in his book The Physical Geography of the Sea.The cable was laid, but not until 1866 was the connection made permanent and reliable. At the early attempts, the cable failed and when it was take
6、n out for repairs it was found to be covered in living growths, a fact which defied contemporary scientific opinion that there was no life in the deeper parts of the sea.Within a few years oceanography was under way. In 1872 Thomson led a scientific expedition (考察), which lasted for four years and b
7、rought home thousands of samples from the sea. Their classification and analysis occupied scientists for years and led to a five-volume report, the last volume being published in 1895.21. The proposal to lay a telegraph cable from Europe to America made oceanographic studies take on _.A) an academic
8、 aspect B) a military aspect C) a business aspect D) an international aspect22. It was _ that asked Maury for help in oceanographic studies.A) the American Navy B) some early intercontinental travelersC) those who earned a living from the sea D) the company which proposed to lay an undersea cable23.
9、 The aim of the voyages Maury was responsible for in the 1840s was _.A) to make some sounding experiments in the oceans B) to collect samples of sea plants and animalsC) to estimate the length of cable that was needed D) to measure the depths of the two oceans24. “Defied” in the 5th paragraph probab
10、ly means “_”.A) doubted B) gave proof to C) challenged D) agreed to25. This passage is mainly about _.A) the beginnings of oceanography B) the laying of the first undersea cableC) the investigation of ocean depths D) the early intercontinental communicationsPassage TwoQuestions 26 to 30 are based on
11、 the following passage.Normally a student must attend a certain number of courses in order to graduate, and each course which he attends gives him a credit which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six courses each lasting for o
12、ne semester. A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester. Normally a student would expect to take four years attending two semesters each year. It is possible to spread th
13、e period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this is not in fact done as a regular practice.For every course that he follows a student is given a grade, which is recorded, and the r
14、ecord is available for the student to show to prospective employers. All this imposes a constant pressure and strain of work, but in spite of this some students still find time for great activity in student affairs. Elections to positions in student organizations arouse much enthusiasm. The effectiv
15、e word of maintaining discipline is usually performed by students who advise the academic authorities. Any student who is thought to have broken the rules, for example, by cheating has to appear before a student court. With the enormous numbers of students, the operation of the system does involve a
16、 certain amount of activity. A student who has held one of these positions of authority is much respected and it will be of benefit to him later in his career.26. Normally a student would at least attend _ classes each week.A) 36 B) 20 C) 12 D) 1527. According to the first paragraph an American stud
17、ent is allowed _.A) to live in a different university B) to take a particular course in a different universityC) to live at home and drive to classes D) to get two degrees from two different universities28. American university students are usually under pressure of work because _.A) their academic p
18、erformance will affect their future careersB) they are heavily involved in student affairsC) they have to observe university disciplineD) they want to run for positions of authority29. Some students are enthusiastic for positions in student organizations probably because _.A) they hate the constant
19、pressure strain of their studyB) they will then be able to stay longer in the universityC) such positions help them get better jobsD) such positions are usually well paid30. The student organizations seem, to be effective in _.A) dealing with the academic affairs of the universityB) ensuring that th
20、e students observe university regulationsC) evaluating students performance by bringing them before a courtD) keeping up the students enthusiasm for social activitiesPassage ThreeQuestions 31 to 35 are based on the following passage.Do you find getting up in the morning so difficult that its painful
21、? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.During the hours when you labor through your work you may say that youre “hot”. Thats true. The time of day when you feel most energetic is when your cycle of body temperatur
22、e is at its peak. For some people the peak comes during the afternoon. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues (自言自语) as: “Get up, John! Youll be late for work again!” The possible explanation to the trouble is t
23、hat John is at his temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has. You cant change your energy cycle, but you can learn to make your life fit it better. Habit can he
24、lp, Dr. Kleitman believes. Maybe youre sleepy in the evening but feel you must stay up late anyway. Counteract (对抗) your cycle to some extent by habitually staying up later than you want to. If our energy is low in the morning but you have an important job to do early in the day, rise before your us
25、ual hour. This wont change your cycle, but youll get up steam (鼓起干劲) and work better at your low point.Get off to a slow start which saves your energy. Get up with a leisurely yawn and stretch.

If one wants to work more efficiently at his low point in the morning, he should _.A) change his energy cycle B) overcome his lazinessC) get up earlier than usual D) go to bed earlier34.

30、ave ones energy.B) Dr. Kleitman explains why people reach their peaks at different hours of day.C) Habit helps a person adapt to his own energy cycle.D) Children have energy cycles, too.Passage FourQuestions 36 to 40 are based on the following passage.We find that bright children are rarely held bac
31、k by mixed ability teaching. On the contrary, both their knowledge and experience are enriched. We feel that there are many disadvantages in streaming (把按能力分班) pupils. It does not take into account the fact that children develop at different rates. It can have a bad effect on both the bright and the not-so-bright child. After all, it can be quite discouraging to be at the bottom of the top grade!Besides, it is rather unreal to grade people just according to their intellectual ability. This is only one aspect of their total personality. We are concerned to develop the abilities of
