　　Part II Reading Comprehension (35 minutes)

　　Directions: There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B),C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single ling through the centre.

　　Passage One

　　Questions 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 nineteenth century, scientists with an interest in the sea were few and far between.

　　 Certainly Newton considered some 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 travellers or others who earned a living from the sea, there was little reason to ask many questions about it , let alone to ask what lay beneath the surface. The first time that the 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 of the route 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　 were taken to investigate the 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 taken 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 , which　 lasted for four years and brought 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.

　　Passage Two

　　Questions 26 to 30 are based on 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 one 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 the 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 very course that the follows a students is given a grade, which is recorded, and the record 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 organisations arouse much enthusiasm. The effective work 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 his to appear before a student court, With the enormous numbers of students, the operation of the system does involve a 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.

　　　Passage Three

　　　Questions 31 to 35 are based on the following passage:

　　Do you find getting up in the morning so difficult that it's painful ? 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 labour through your work you may say that you're "hot". That's true. The　time of day when you feel most energetic is when your cycle of bady temperature is at its peak . For some　people the peak comes during the forenoon. For others it comes in the afternoon or evening No one has　discovered why this is so , but it leads to such familiar monologues as : "Get up, John! You'll be late for　work again !" The possible explanation to the trouble is that 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 can't change your energy cycle, but you can learn to make your life fit it better. Habit can help,　Dr. Kleitman believes . Maybe you're sleepy in the evening but feel you must stay up late anyway . Counteract 　your cycle to some extent by habitually staying up later than you want to .If your energy is low in the morning　but you have an important job to do early in the day, rise before your usual hour. This won't change your cycle, but you'll get up steam 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 . Sit on the edge　of the bed a minute before putting your feet on the floor . Avoid the troublesome search for clean clothes by　laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring　more energy or concentration for your sharper hours.

　　

　　31. If a person finds getting up early a problem , most probably _______.

　　 A)he is a lazy person

　　 B)he refuses to follow his own energy cycle

　　 C)he is not sure when his energy is low

　　 D)he is at his peak in the afternoon or evening

　　

　　32. Which of the following may lead to family quarrels according to the passage?

　　 A) Unawareness of energy cycles.

　　 B) Familiar monologues.

　　 C) A change in a family member's energy cycle.

　　 D) Attempts to control the energy cycle of other family members.

　　

　　33.If one wants to work more efficiently at his how point in the morning, he should _____.

　　 A)change his energy cycle

　　 B)overcome his laziness

　　 C)get up earlier than usual

　　 D)go to bed earlier
