To be happy,a man must feel,firstly,free and,secondly,important. He cannot be really happ

18、y if he is compelled by society to do what he does not enjoy doing,or if what he enjoys doing is ignored by society as of no value or importance. In a society where slavery in the strict sense has been abolished,the sign that what a man does is of social value is that he is paid money to do it,but a

19、 laborer today can rightly be called a wage slave. A man is a laborer if the job society offers him is of no interest to himself but he is compelled to take it by the necessity of earning a living and supporting his family. The antithesis to labor is play. When we play a game,we enjoy what we are do

20、ing,otherwise we should not play it,but it is a purely private activity;society could not care less whether we play it or not. Between labor and play stands work. A man is a worker if he is personally interested in the job which society pays him to do:what from the point of view of society is necess

21、ary labor is from his own point of view voluntary play. Whether a job is to be classified as labor or work depends,not on the job itself,but on the tastes of the individual who undertakes it. The difference does not,for example,coincide with the difference between a manual and a mental job;a gardene

22、r or cobbler may be a worker,a bank clerk,a laborer. Which a man is can be seen from his attitude toward leisure. To a worker, leisure means simply the hours he needs to relax and rest in order to work efficiently. He is therefore more likely to take too little leisure than too much;workers die of c

23、oronaries and forget their wives birthdays. To the laborer,on the other hand,leisure means freedom from compulsion,so that it is natural for him to imagine the fewer hours he has to spend laboring,and the more hours he is free to play,the better. 36 The best title for the passage could be_. （ A） Wor

24、k,Labor and Play （ B） Ways Leading to Happiness （ C） The Most Desirable Job in the World （ D） The Necessity of Leisure 37 If a person wishes to be happy,_. （ A） he must have something to do （ B） he must realize the essential difference between work and labor （ C） he must feel free first of all （ D）

25、he must do something valuable to society 38 A man is a laborer if_. （ A） what he likes to do is not recognized by society （ B） he has to make a living or supporting his family （ C） he cannot get paid for what he does （ D） he is forced to do what he doesnt enjoy 39 According to the passage,what is so

26、cietys attitude toward the game we play? （ A） Society regards play as another kind of labor. （ B） Society doesnt care what we play at all. （ C） Society forbids us to play any game. （ D） Society cares for private games very much. 40 Which of the following kinds of person is a worker? （ A） A teacher w

27、ho enjoys working with students. （ B） A white-collar employee who is well paid. （ C） A man who doesnt mix work with play. （ D） A man who has good appetite and enjoys goods health. 41 What does the laborer think of leisure? （ A） He thinks he has no time for it since he has to support his family. （ B）

28、 He wishes to have as little leisure as possible. （ C） He hopes to have more leisure to play. （ D） He thinks it more important than health and family. 41 Every living thing has an inner biological clock that controls behavior. The clock works all the time even when there are no outside signs to mark

29、 the passing of time. The biological clock tells plants when to form flowers and when the flowers should open. It tells insect when to leave the protective cocoon and fly away. And it tells animals when to eat,sleep and wake. It controls body temperature,the release of some hormones and even dreams.

30、 These natural daily events are circadian rhythms. Man has known about them for thousands of years. But the first scientific observation of circadian rhythms was not made until 1729. In that year French astronomer,Jean-Jacquesd“Ortous de Mairan“,noted that one of his plants opened its leaves at the

31、same time every morning,and closed them at the same time every night. The plant did this even when he kept it in a dark place all the time. Later scientists wondered about circadian rhythms in humans. They learned that mans biological clock actually keeps time with a day of a little less than 25 hou

32、rs instead of the 24 hours on a man-made clock. About four years a-go an American doctor,Eliot Weitzman,established a laboratory to study how our biological clock works. The people in his experiments are shut off from the outside world. They are free to listen to and live by their circadian rhythms.

33、 Dr. Weitzman hopes his research will lead to effective treatments for common sleep problems and sleep disorders caused by aging and mental illness. The laboratory is in the Monte-flore Hospital in New York City. It has two living areas with three small rooms in each. The windows are covered,so no s

34、unlight or moonlight comes in. There are no radios or television receivers. There is a control room between the living areas. It contains computers,one-way cameras and other electronic devices for observing the person in the living area. The instruments measure heartbeat,body temperature,hormones in

35、 the blood,other substances in the urine and brain waves during sleep. A doctor or medical technician is on duty in the control room 24 hours a day during an experiment. They do not work the same time each day and are not permitted to wear watches,so the person in the laboratory has no idea what tim

36、e it is. In the first four years of research,Dr. Weitzman and his assistant have observed 16 men between the ages of 21 and 80. The men remained in the laboratory for as long as six months. Last month,a science reporter for The New York Times newspaper,Dava Sobol,became the first woman to take part

37、in the experiment. She entered the laboratory on June 13th and stayed for 25 days. Miss Sobol wrote reports about the experiment during that time, which were published in the newspaper. 42 The biological clock is believed to play an essential role in_. （ A） the regulation of body temperature （ B） th

38、e secretion of hormones （ C） animal reproduction （ D） many aspects of plant and animal physiology 43 In his observation, the French scientist noticed that the leaves of a certain plant maintained its open-ing-and-closing cycles_. （ A） even when it was kept in a murky place all day （ B） even if it wa

39、s placed in the moonlight （ C） even when he was observing it from a dark place （ D） even during the night time 44 The sentence “They are free to listen to and live by their circadian rhythms. “(Para. 2)probably means_. （ A） They can lead their daily lives according to their biological clocks, withou

40、t referring to a manmade clock （ B） They can listen to the wonderful rhythms of the biological clock and live close to them （ C） They can live by regulating their own circadian rhythms （ D） They are free from the annoying rhythms of everyday life 45 In the experiment conducted by Mr. Weitzman,the do

41、ctor who is on duty does not work the same time each day_. （ A） in order to observe the abnormal behavior of the people at different times （ B） so as not to be recognized by the people （ C） so as to avoid indicating to the people what time it is when he starts work （ D） so as to leave the peoples ci

42、rcadian rhythms in disorder 46 What is Mr. Weitzmans ultimate purpose of establishing a laboratory? （ A） He wanted to have his experiment report published in the newspapers. （ B） People are free to listen to and live by their circadian rhythms. （ C） He wanted to find a way to treat peoples diseases.

43、 （ D） He could gain some reputation for the first scientific observation of circadian. 47 Miss Sobol left the laboratory_. （ A） on June 13th （ B） on June 25th （ C） at the end of June （ D） on July 7th 47 There are hidden factors which scientists call “feedback mechanisms“. No one knows quite how they

44、 will interact with the changing climate. Heres one example:plants and animals adapt to climate change over centuries. At the current estimate of half a degree centigrade of warming per decade,vegetation may not keep up. Climatologist James Hansen predicts climate zones will shift toward the poles b

45、y 50 to 75 kilometers a yearfaster than trees can naturally migrate. Species that find themselves in an unfamiliar environment will die. The 1,000-kilometer-wide strip of forest running through Canada,Russia,and Scandinavia could be cut by half. Millions of dying tress would soon lead to massive for

46、est fires, releasing tons of CO2 and further boosting global warming. There are dozens of other possible “feedback mechanisms“. Higher temperatures will fuel condensation and increase cloudiness, which may actually damp down global warming. Others,like the“albedo“ef-fect is the amount of solar energ

47、y reflected by the earths surface. As northern ice and snow melts and the darker sea and land pokes through,more heat will be absorbed,adding to the global temperature increase. Even if we were to magically stop all greenhouse-gas emissions tomorrow,the impact on global climate would continue for de

48、cades. Delay will simply make the problem worse. The fact is that some of us are doing quite well the way things are. In the developed world prosperity has been built on 150 years of cheap fossil fuels. Material progress has been linked to energy consumption. Today 75 percent of all the worlds energ

49、y is consumed by a quarter of the worlds population. The average rich-world resident adds about 3.2 tons of CO2 yearly to the atmosphere,more than four times the level added by each Third World citizen. The US,with just seven percent of the global population,is responsible for 22 percent of global warming. 48 “Feedback mechanisms“in paragraph 1 most probably refer to_. （ A） how pl
