Normally an individual thunderstorm lasts about 45 minutes, but under certain conditions the storm may ______, becoming ever more severe, for as long as four hours.
A
wane
B
moderate
C
persist
D
endure
E
vacillate
F
disperse
参考答案
参考解析
解析：
句中的提示信息是“becoming ever more severe”，说明有些情况下，雷暴会变得更加猛烈，由此可以排除A wane（衰落；变小；消逝），B moderate（变缓和，变弱）和F disperse（分散；使散开）；根据句意，由于雷暴变得更加猛烈，相对于正常情况下持续45分钟，特定情况下的雷暴可能会持续长达4小时，因此选项中符合句意且意思相近的只有C persist（持续，坚持；存留）和D endure（持续；忍耐）；E vacillate 犹豫，踌躇，与句意不符，因此选择C和D。

During sleep, the fatigue (疲劳) of the body disappears and recuperation ( 恢复) begins. The tired mind gathers new energy. Once awake, the memory improves, and annoyance and problems are seen in a better perspective.Some adults require little sleep; others need eight to ten hours in every twenty-four. Infants sleep sixteen to eighteen hours daily and, as they grow older, the amount gradually diminishes. Young students may need twelve hours; university students may need ten. A worker with a physically demanding job may also need ten, whereas an executive worker under great pressure may manage on six to eight. Many famous people are reputed to have required little sleep. Napoleon, Thomas Edison and Charles Darwin apparently averaged only four to six hours a night.Whatever your individual need, you can be sure that by the age of thirty you will have slept for a total of more than twelve years. By that age you will also have developed a sleep routine: a favorite hour, a favorite bed, a favorite position, and a formula you need to follow in order to rest comfortably. Investigators have tried to find out how long a person can go without sleep. Several people have reached more than 115 hours ?nearly five days, whereas animals kept awake for from five to eight days have died of exhaustion. The limit for human beings is probably about a week.1、The writer implies that _________A、sleep is important for good mental and physical healthB、a light sleep is as restful as a deep sleepC、memory is improved during sleepD、sleep is relatively unimportant for human beings2、From the amount of sleep Napoleon, Edison and Darwin required, we can infer that_______.A、they were famous great menB、 they were executive workersC、 they were intelligent peopleD、 they were involved in mentally demanding work3、The amount of sleep required ________.A、varies greatly from individual to individualB、 depends on an individual''s ageC、 relates to an individual''s occupationD、 all of the above.4、According to the passage, the sleeping routine will be built at the age of _________.A、10B、20C、30D、405、From animal experiments, we can conclude that the final result of the lack of sleep is probably _________A、mental illnessB、mental breakdownC、susceptibility to illnessD、death

Part CDirections: Read then following text carefully and then translate the underlined segments into Chinese. Your translation should be written clearly on ANSWER SHEET Ⅱ. ( 10 points)Laws of nature are of two basic forms: (1) a law is Universal if it states that some conditions, so far as are known, in- variably are found together with certain other conditions; and (2) a law is probabilistic if it affirms that, on the average, a stated fraction of cases displaying a given condition will display a certain other condition as well. In either case, a law may be valid even though it obtains only under special circumstances or as a convenient approximation.46) Moreover, a law of nature has no logical necessity; rather, it rests directly or indirectly upon the evidence of experience. Laws of universal form. must be distinguished from generalizations, such as "All chairs in this office are gray," which appear to be accidental. Generalizations, for example, cannot support counterfactual conditional statements such as "If this chair had been in my office, it would be gray" nor subjunctive conditionals such as "If this chair were put in my office, it would be gray." On the other hand, the statement "All planetary objects move in nearly elliptical paths about their star" does provide this support. All scientific laws appear to give similar results.47) The class of universal statements that can be candidates for the status of laws, however, is determined at any time in history, by the theories of science current then.Several positive attributes are commonly required of a natural law. Statements about things or events limited to one location or one date cannot be lawlike. Also, most scientists hold that the predicate must apply to evidence not used in deft- ring the law: though the law is founded upon experience, it must predict or help one to understand matters not included among these experiences. Finally, it is normally expected that o law will be explainable by more embracing laws or by some theory.48) Thus t a regularity for which there are general theoretical grounds for expecting it will be more readily called a natural law than an empirical regularity that cannot be subsumed under more general laws or theories.Universal laws are of several types. 49) Many assert a dependence between varying quantities measuring certain properties, as in the law that the pressure of a gas under steady temperature is inversely proportional to its volnme.Others state that events occur in an invariant order, as in "Vertebrates always occur in the fossil record after the rise of invertebrates." Lastly, there are laws affirming that if an object is of a stated sort it will have certain observable properties. 50) Part of the reason for the ambiguity of the term law of nature lies in the temptation to apply the term only to statements of one of these sorts of laws, as in the claim that science deals solely with cause and effect relationships, when in fact all three kinds are equally valid.46.____________________

At the first sight the planet Mars does not appear very welcome to any kind of life．It has very little oxygen and water,the temperature at night is below-50~Cand winds of 100 miles per hour cause severe dust storms．However,the surface of the planet seems to show that water flowed across it some time in the past,and it is believed that there is enough ice at the poles to cover the planet with water if it melts．Although there is no life on the Mars now,some scientists think that there may have been some form of life long time ago．At that time,the planet had active volcanoes;the atmosphere was thicker and warmer;and there was water．In fact,in some ways the Mars may have been similar to the Earth,where life exists.
Some people believe that the Mars could support life in the future if the right conditions were produced．The first step would be to warm the planet using certain gases which trap the Sun's heat in the planet's atmosphere．With warmth,water and carbon dioxide(二氧化碳),simple plants could begin to grow．These plants could slowly make the Mars more suitable for living．It is estimated that the whole process might take between 100,000 and 200,000 years．In the meantime,people could begin to live on the planet in special closed environments．They would provide a lot of useful information about conditions on the Mars and the problems connected with living there.
Which is the best title for this passage?A.The Possibility of Life on the Mars
B.Future Conditions on the Mars
C.The Mars and the Earth
D.A Study of the Climate of the Mars

The First Four MinutesWhen do people decide whether or not they want to become friends?During their first four minutes together,according to a book by Dr. Leonard Zunin.In his book,Contact:The First Four Minutes,he offers this advice to anyone interested in starting new friendships:"________(46)A lot of people's whole lives would change if they did just that."You may have noticed that the average person does not give his undivided attention to someone he has just met._________(47)If anyone has ever done this to you,you probably did not like him very much.When we are introduced to new people,the author suggests,we should try to appear friendly and self-confident. In general,he says,"People like people who like themselves".On the other hand,we should not make the other person think we are too sure of ourselves.It is important to appear interested and sympathetic,realizing that the other person has his own needs,fears,and hopes.Hearing such advice,one might say,"But I'm not a friendly,self-confident person.That's not my nature.It would be dishonest for me to act that way."__________(48)We can become accustomed to any changes we choose to make in our personality."It is like getting used to a new car. It may be unfamiliar at first,but it goes much better than the old one."But isn't it dishonest to give the appearance of friendly self-confidence when we don't actually feel that way?Perhaps,but according to Dr. Zunin,"total honesty"is not always good for social relationships, especially during the first few minutes of contact. There is a time for everything,and a certain amount of play-acting may be best for the first few minutes of contact with a stranger. That is not the time to complainabout one's health or to mention faults one finds in other people.It is not the time to tell the whole truth about one's opinions and impressions.________(49)For a husband and wife or a parent and child,problems often arise during their first four minutes together after they have been apart. Dr. Zunin suggests that these first few minutes together be treated with care.If there are unpleasant matters to be discussed,they should be dealt with later.The author says that interpersonal relations should be taught as a required course in every school,along with reading,writing,and mathematics.__________(50)That is at least as important as how much we know._________（49）A:In reply,Dr. Zunin would claim that a little practice can help us feel comfortable about changing our social habits.B:Much of what has been said about strangers also applies to relationships with family members and friends.C:In his opinion,success in life depends mainly on how we get along with other people.D:Every time you meet someone in a social situation,give him your undivided attention for four minutes.E:He keeps looking over the other person'S shoulder,as if hoping to find someone more interesting in another part of the room.F:He is eager to make friends with everyone.
