You should choose the right answer that best fits into the passage.Scientists used to explore 31 the surface of the ocean. Now they 32 below the surface,too. They want to know about the ocean water and the 33 and animal life 34 in the ocean.In 1934 the scientist William Beebe dived 3,000 feet below the surface in a hollow steel ball. In 1935 Auguste Picard dived 10,330 feet. In 1960 his son Jean dived to a 35 of 35,800 feet.All these early dives were deep. But the divers could not stay down for very long. They had to 36 the surface after a few seconds. Scientists needed to stay down longer to study life below the surface. 37 ,they succeeded. Cousteau,a Frenchman,was able to 38 down to a depth of 36 feet for one month and to a depth of 90 feet for a week.Now scientists are developing even 39 equipment. With this new equipment,men can stay 40 the surface for days or 41 weeks. In 1962 Consteau 42 a research station 35 feet below the surface. Then in 1964 he set up another station on the ocean floor of the Red Sea.This was the first undersea station to operate 43 help from the surface.Many countries are now studying undersea 44 . The Soviet Union has an undersea laboratory in the Crimean Sea. The United States has a laboratory 50 feet 45 on the ocean floor 46 the Virgin Islands. In 1970 five men lived there for two weeks. Then a 47 of five women scientists stayed in the laboratory. 48 came other teams of men. All were there to explore the ocean depths and 49 plans for the use of its resources. Scientists hope to find enough 50 ,vegetable,and animal wealth there to provide food for the whole world.31. A. in B. to C. On D. under32. A. explore B. are exploring C. explored D. will explore33.

Each passage is followed by some questions orunfinished statements. For each of them there are four choices marked A, B, C and D, you should decide the best choice.Passage 1With a tremendous roar from its rocket engine,the satellite is sent up into the sky. Minutes later,at an altitude of 300 miles,this tiny electronic moon begins to orbit about the earth. Its radio begins to transmit a staggering amount of information about the satellite’s orbital path,the amount of radiation it detects,and the presence of meteorites. Information of all kinds races back to the earth. No human being could possibly copy down all these facts,much less remember and organize them. But an electronic computer can.The marvel of the machine age,the electronic computer has been in use only since 1946. It can do simple computations—add,subtract,multiply,and divide—with lightning speed and perfect accuracy. It can multiply two 10digit numbers in 1/1,000 second,a problem that would take an average person five minutes to do with pencil and paper. Some computers can work 500,000 times faster than any person can.Once it is given a program,that is,a carefully worked out set of instructions devised by a technician trained in computer language,a computer can gather a wide range of information for many purposes. For the scientist it can get information from outer space or from the depths of the ocean. In business and industry the computer prepares factory inventories,keeps track of sales trends and production needs,mails dividend checks,and makes out company payrolls. It can keep bank accounts up to date and make out electric bills. If you are planning a trip by plane,the computer will find out what route to take and what space is available.51. Why does the author regard the electronic computer as the marvel of the machine age?A. Because electronic computers are rare.B. Because people know little about electronic computers.C. Because electronic computers can do much more kinds of work that human beings can’t.D. Because electronic computers have been widely suspected.52. Electronic computers were given the name in the beginning just for the simple reason that_______ .A. they could do computationsB. they could work much faster than human beingsC. they looked like an abacusD. they could remember data quickly53. According to the passage,which of the following is NOT true?A. Computers began to be used in 1946.B. Computers can add,subtract,multiply and divide.C. Computers were widely used during World War Ⅱ.D. No human being can work as fast as a computer.54. A computer can calculate_______.A. with lightning speedB. accuratelyC. with a speed 500,000 times faster than a personD. all above55. In the first sentence of last paragraph,“program” would probably mean_______.A. a performanceB. a showC. a worked out set of instructionsD. a TV playPassage 2On the old time farm in America there were chickens and turkeys. There were also cows,pigs,and other livestock. But there were very few machines. Most of the work was done by the entire farm family with the h elp of a “hired” man. Sometimes extra labourers were needed in busy seasons. Horses provided 79 percent of the power used,human labor 15 percent,and machines only 6 percent.Today all that has changed. On many modern farms machines now supply 96 percent of the power,human labor 3 percent,and horses 1 percent. Modern farms are enterprising businesses which keep only the livestock that can pay its way. The children go to school by bus every morning,the parents work on the farm or in the house,and hired help is seldom needed. Their work has been replaced by a whole army of farm machines.Farmers in the machine age also use the new fertilizers,new sprays,new feeds,new hybrid seeds,and other helps developed by farm sciences. As a result the farmers are able to produce more food with less labour. This means fewer but larger farms and fewer but moreprosperous farmers.56. In old days,most of the work on a farm was done by_______.A. all the farm familyB. livestockC. farm machinesD. both A and B57. From the first paragraph,we learn that in old days the most important farming power was____.A. LivestockB. farmersC. MachinesD. extra laborers58. On today’s farms,the chief reason why livestock is still raised would probably be____.A. that farmers conventions are difficult to be given upB. that farmers want to gain more profitC. that farmers have to do soD. that farmers work has been replaced by machines59. On modern farms,farmers need mostly all the followings EXCEPT_______.A. farm scienceB. seedsC. FertilizersD. hard work60. In the last sentence of Paragraph 3,“fewer but larger farms and fewer but more prosperous farmers” means_______.A. hired help is seldom neededB. productivity on the farms has been raised greatlyC. productivity on the farms has fallen sharplyD. more food is never neededPassage 3City traffic jam—one of the least wanted effects of the motor vehicle—is something with which we’re all familiar and for which most of us have an answer. But which solution is best?Some people suggest for better roads,others for cars to be banned(禁止) from city centers and yet others say better public transport would attract drivers from their lonely and boring journeys.But the important question is what natural power creates a big city center. We are,after all,in an age of electronic communication; our big shopping areas have moved out of city centers,and our living areas moved out of them long ago.Yet some force causes offices and service industries related to them to gather in London or New York or Tokyo. This suggests that far from the problems of a crowded environment forcing companies and people to move out,there is a critical (重大的) size beyond which more companies are attracted to move in. Nobody seems to know why,yet the answer is important to the way traffic jam is dealt with.61. Which of the following is NOT mentioned in the passage as the cause of the traffic problem?A. The poor public transport.B. The over concentration of shopping centers.C. The great number of cars in the city centers.D. The bad road conditions.62. According to the passage,offices and their associated service industries move to big cities because of_______.A. the convenience of communicationB. the gathering of companiesC. some unknown forceD. the convenience of shopping63. The word “This”(Line 2,Para.4) refers to_______.A. some forceB. traffic jamC. the force that causes offices to move in or outD. the fact that companies gather in big cities64. This passage is most likely taken from_______.A. a novelB. a TV playC. an instructionD. a news report65. The topic of this passage would probably be_______.A. Best Answer to Traffic ProblemB. The Banning of Cars in the City CenterC. The Formation of City CenterD. Searching for Ways to Solve Traffic ProblemPassage 4Mrs. Cox teaches English in a large high school located in the inner area of a big city on the West Coast. Ever since she was a young girl,Mrs. Cox had wanted to become a teacher. She has taught eight years now and hasn’t changed her mind.After she graduated from high school,Mrs. Cox went on to college. Four years later,she received her bachelor’s degree (B.A.) in English and her teaching certificate. Then she was qualified to teach in the secondary schools of her state. In the summers,Mrs. Cox takes more classes. Someday she hopes to get a master’s degree (M.A.).With an M.A.,she will receive a higher salary.The school day at Mrs. Cox’s high school,like that in many high schools in the United States,is divided into six periods of one hour each. Mrs. Cox must teach five of these six periods. During her free period,which for her is from 2 to 3 p.m.,Mrs. Cox must meet with parents,order supplies,make out examinations,check assignments,and take care of many other things. In short,her free period isn’t really free at all. Mrs. Cox works steadily from the time she arrives at school in the morning until the time she leaves for home late in the afternoon.66. Mrs. Cox wants to be a teacher because_______.A. she likes teachingB. she is a young girlC. she has many problems to deal withD. she doesn’t mind what she is doing67. From paragraph two,we can infer_______.A. Mrs. Cox has received a teaching certificateB. Mrs. Cox likes teaching very muchC. Mrs. Cox takes more classesD. Mrs. Cox is a qualified teacher68. She will receive a higher salary if_______.A. she gets a master’s degreeB. she takes more classesC. she has studies normal teachingD. she gets a bachelor’s degree69. According to the passage, all the followings are true EXCEPT_______.A. she graduated from high schoolB. she graduated from collegeC. she has got her bachelor’s degreeD. she teaches five periods for a school day70. The best title for the passage would probably be_______.A. A Typical School DayB. Teacher Mrs. CoxC. Mrs. Cox Likes TeachingD. Mrs. Cox Has Got Her Teaching CertificatePart Ⅳ Translation (2.5×8 points)Section ADirections:There are 4 sentences in this section. You are required to translate them from Chinese into English.71.这口大钟大约有三个人那么高。
