2. Passage ThirtyThe Chinese have used a method called acupuncture (针灸)to help perform operations for about 4, 000 years without putting the patient to sleep.This involves inserting flexible needles into certain parts of the body.The needles are available in a number of stores in China and everyone may buy them.To learn how to use needles takes about one month of training.But to be skillful requires greater time.The person who performs the acupuncture knows how to put in the needles so the needles themselves are not painful.This person also knows where to place the needles so the patient feels no pain in the area where the operation is to be performed.In the past, a particular operation might require 25 or more needles placed in various parts of the body.But now this operation requires only 3 or 4 needles.Today, the Chinese doctors are trying to learn more about acupuncture.They are trying to develop a convincing theory to explain how the needles work in preventing pain, or why a needle in the wrist, for example, would prevent the pain in the area of the mouth.A patient who needs an operation is given a choice between having acupuncture or having one of the chemicals used for putting him to sleep.It has been estimated that over half of the patients choose acupuncture because there is no sickness after the operation whereas the chemical may make the patient sick for a few hours or a day.Which statement is NOT true of the performer of acupuncture?

1. Passage SeventeenNo one knows how man learned to make words.Perhaps he began by making sounds like those made by animals.Perhaps he grunted like a pig when he lifted something heavy.Perhaps he made sounds like those he heard all round him——water splashing, bees humming, a stone falling to the ground.Somehow, he learned to make words.As the centuries went by, he made more and more new words.This is what we mean by language.People living in different countries made different kinds of words.Today there are about fifteen hundred different languages in the world.Each contains many thousands of words.A very large English dictionary, for example, contains four or five hundred thousand words.But we do not need all these.Only a few thousand words are used in everyday life.The words you know are called your vocabulary.You should try to make your vocabulary bigger.You’re supposed to read as many books as you can.There are plenty of books written in easy English for you to read.You will enjoy them.When you meet a new word, you should find it in your dictionary.Your dictionary is your most useful book.From this passage, we know that ().

1. Passage Twenty-SixToday just as technology changed the face of industry, farmers have undergone an “agricultural revolution”.On the farm of today, machines provide all the power.One of the most important benefits will be the farm computer.A few forward-looking farmers are already using computers to help them run their farms more efficiently.The computers help them keep more accurate records, so they can make better decisions on what crops to plant, how much livestock to buy, when to sell their products, and how much profit they can expect.Many computer companies have been developing special computer programs just for farmers.Programs are being written for hog (猪)producers, grain farmers, potato farmers, and dairy farmers.In the future, farmers will be able to purchase computer programs made to their needs.Because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses.There can be no doubt that farmers will rely on computers even more in the future.While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power.Another technological advance which is still in the experimental stage is the robot, a real “mechanized hired hand” that will be able to move and, in some ways, think like a human being.Agricultural engineers believe that computer-aided robots will make startling changes in farming before the end of the century.Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them.Scientists are now developing robots that will be able to shear (修剪)sheep, drive tractors, and harvest fruit.Even complex jobs will be done by robots.For example, in order to milk their cows, farmers must first drive them into the special barn (畜棚), then connect them to the milking machines, watch the machines, and disconnect them when they are finished.In the future, this will all be done by robots.In addition, when the milking is completed, the robots will automatically check to make sure that the milk is pure.The complete mobilization of the farm is far in the future, but engineers expect that some robots will be used before long.Which sentence is the main idea of the whole passage?

3. Passage TenNowadays, children heavily cling to digital devices such as computers and smart phones.Some spend up to six hours a day on their digital devices.They can be playing games online with people elsewhere, updating their status on social media, texting friends, or looking for the latest apps to download to their computers or smart phones.This worried Martin Strott.He is the headmaster of the Old Hall School in Wellington, England.He was so concerned that he challenged his students to take part in a week of (“digital detox”), a program to reduce their reliance on digital devices.Mr.Strott told the local newspaper, the Shropshire Star, that too much screen time would affect the development of their social skills.At another interview with a magazine, he mentioned that this over-reliance on digital devices “takes away family time and reduces their chances of face-to-face communication”.The parents are happy with the program.But what about the children? Nine-year-old Fred usually spends around two hours on his digital devices at home after school and around 12 hours on weekends.For him, the digital detox experience was “really hard”.He said that he had been engaged in many interesting outdoor activities organized by the headmaster, but still missed his phone and online games.The idea of keeping children away from their digital devices for a while to prevent too much dependence on them is not particularly new.There have been similar practices in the United States.But are they effective in the long run? According to Mr.Strott, even if kids go back to their digital devices, the hope is that at least they will think about how they will use their time.The Shropshire Star is ().

4. Passage Thirty-FourMuch unfriendly feeling towards computers has been based on the fear of widespread unemployment resulting from their introduction.Computers are often used as part of automated (自动化的)production systems requiring a least possible number of operators, causing the loss of many jobs.This has happened, for example, in many steelworks.On the other hand, computers do create jobs.They are more skilled and better paid, though fewer in number than those they replace.Many activities could not continue in their present form without computers, no matter how many people are employed.Examples are the check clearing (交换)system of major banks and the weather forecasting system.When a firm introduces computers, a few people are usually employed in key posts (such as jobs of operations managers)while other staff are re-trained as operators, programmers, and data preparation staff.After the new system has settled down, people in non-computer jobs are not always replaced when they leave, resulting in a decrease in the number of employees.This decrease is sometimes balanced by a substantial increase in the activity of the firm, resulting from the introduction of computers.The attitudes of workers towards computers vary.There is fear of widespread unemployment and of the takeover of many jobs by computer-trained workers, making promotion for older workers not skilled in computers more difficult.On the other hand, many workers regard the trend toward wider use of computers inevitable.They realize that computers bring about greater efficiency and productivity, which will improve the condition of the whole economy, and lead to the creation of more jobs.This view was supported by the former British Prime Minister, James Callaghan in 1954, when he made the point that new technologies hold the key to increased productivity, which will benefit the economy in the long run.According to the passage, what results from the introduction of computers?

5. Passage NineteenA 3-year-old boy who was lost in the woods for two days is now safe at home.But Casey Hathaway told his rescuers that he was not alone in the rainy, freezing cold woods.He said he was with a friend——a bear.The child went missing on January 22 while playing with friends at his grandmother’s house in the southern state of North Carolina.When the other children returned to the house and Casey did not, the family searched the area for almost an hour before calling the police.Police formed a search and rescue team to look for the young boy in the nearby woods.But two days went by and still——no Casey.The woods of North Carolina are home to many black bears, like this one.It seems one of them helped a little boy while he was lost in the woods.Then on January 24, someone called the police saying they heard a child crying in the woods.Police followed up on the information and found Casey at about 9:30 that night.They pulled him out of some briar (荆棘).He was in good health.Police Officer Chip Hughes said that Casey did not say how he was able to survive in the woods for two days in the cloud, rainy weather, but that “he did say he had a friend in the woods that was a bear that was with him.”Hundreds of people helped in the search and rescue efforts, including some 600 volunteers, federal police and members of the military.Hughes told reporters that at no point did he think Casey had been kidnapped (绑架).Doctors at Carolina East Medical Center treated Casey for minor injuries.He was then released to his family on January 25.All the following are mentioned as those helping in the rescue efforts EXCEPT ().
