But it is also true that many children today are using computers at school before they can write. What does this mean for the future? Are these children lucky or not?Many people who do not know about computers think of them as machines that children play with. They worry that children do riot learn from experience but just from pressing a button and that this is not good for them. They think that children are growing not knowing about the real world.But people who understand more about computers see that computers can be very good for children. A computer can help them to learn about the real world more quickly, to learn what they want to learn and to think for themselves. And for the future, don't we need people who can think clearly, who know how to get information quickly and use it well? What do you think?6.

No, he doesn't think so.C. He doesn't know.D. It isn't mentioned.CEducation is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them. Our purpose is to fit them for life.In some modem countries it has for some time been fashionable（时兴的）to think that by free education for all whether rich or poor, clever or stupid-one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degrees, they refused to do what they think "low" work, and, in fact, work with hands is thought to be dirty and shameful in such countries. But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor, we can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we should get terrible diseases in our towns. . .In fact, when we say that all of us must be educated to fit us for life, it means that we must be educated in such a way that, firstly, each of us can do whatever work suited to his brains and ability and, secondly, that we can realize that all jobs are necessary to society, and that it is very bad to be ashamed of one's work. Only such a type of education can be considered valuable to society.11. The writer of this passage think that ________.A. education can settle all of the world's problemsB. free education for all probably leads to a perfect worldC. free education won't help to solve social problemsD. all the social problems can't be solved by education12. The writer wants to prove that ________.A. our society needs all kinds of jobsB. our society needs free education for allC. a farmer is more important than a professorD. people with university degrees refuse to do what they think "low" work13. According to the passage ________.A. work with hands is dirty and shamefulB. work with hands is low workC. work with hands is the most importantD. we can't regard work with hands as low work14. The purpose of education is ________.A. to choose a system of educationB. to prepare children mainly for their future workC. to let everyone receive education fit for himD. to build a perfect world15. The passage tells us about ________ of education.A. the meansB. the systemC. the valueD. the typeDThe eastern Indonesian island of Komodo is proving a hit with adventurous tourists eager to catch a glimpse of the world's largest lizard species. The island is home to the giant lizard called the Komodo dragon.A descendant of the Jurassic period dinosaurs 130 million years ago, the Komodo dragon is threatened with extinction and has been placed under protection by the Indonesian government.The giant lizard is called "Buays Darat" by the local people who show great respect for the species. Tales handed down over generations of islanders speak of the dragon warning people of approaching crocodiles.The animal can reach a length of three meters when fully grown, attain a weight of about 135 kilograms and may live to an age of about 100 years. It digs a burrow as deep as 9 metres and lays eggs－up to 30 at a time－that hatch in April or May. The newly hatched lizards, about 45 centimeters long, live in trees for several months.Komodo dragons have been known to eat smaller members of the species and sometimes even other adults. The Komodo dragon was first discovered in 1912 by a group of fishermen who took refuge on the island from a storm in the Banda Sea.Various species of the Komodo dragon are also found in Asia, Australia and Africa, but it is only on Komodo and the western tip of the neighboring island of Flores that they grow up to three metres long.16.

Tourists want to visit the island of Komodo because ______.A. of the spectacular sights and scenery.B. it is likely that the dragon will soon he extinct.C. they have a chance of seeing the Komodo dragon.D. they wish to help in the preservation of the dragon.18.

Newborn Komodo dragons ______.A. dig very deep burrows.B. are hatched in captivity.C. hatch towards the end of the year.D. spend the first months of their lives living in trees.20. According to the information presented, which of the following statements is TRUE?A. They weigh up to 135 kilograms and are 9 metres long.B. They weigh 45 kilograms and live up to 135 years.C. They are 3 metres long and live up to 100 years.D. They are 9 metres long and live up to 100 years.21. The local people have great respect for the Komodo dragon becauseA. they believe the dragon protects than from crocodiles.B. they believe the dragon has special healing powers.C. it has evolved from the Jurassic period.D. it is in danger of becoming extinct.EThere is an English saying; "Laughter is the best medicine." Until recently, few people took the saying seriously. Now, however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people's health.Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, the heart beating and breathing, it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programme. The reason why laughter can reducepain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain.As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they try to improve their patients' condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.22. Doctors have proved the following except ________.A. smiling does good to healthB. laughter can be toleratedC. there is a way to reduce painD. laughter can work the muscles in the feet23. The main idea of the passage is ________.A. laughter and physical exercise have similar effects on the human bodyB. smile can produce the same effects as laughterC. pain can be reduced by laughterD. laughter is the best medicine24. The students who ________ tolerated the pain for the longest time.A. listened to different radio programmesB. could produce a kind of chemicalC. don't have stress or painD. listened to a funny programme25. The relationship between laughter and health is like the relationship between ________.A. theory and practiceB. example and main ideaC. help and acceptanceD. teaching and learning26. Doctors hold laughter clinics ________.A. to give better condition to their patientsB. in order to improve patients' healthC. to make patients smileD. to prove smile and laughter have the same effect四、短文改错We are all busy talking about and use the Internet 1.______ which set up in the 1960s .At first, the Internet was 2.______ only used by the government, but, in the early 1970s, 3._____ the universities, hospitals and banks were allowed to 4.______ use it too .However .computers were even very expensive 5._____ and the Internet was difficult to use it.

什么是机器人
美国是机器人的诞生地，早在1962年就研制出世界上第一台工业机器人，
比起号称"机器人王国"的日本起步至少要早五六年。
经过30多年的发展，美国现已成为世界上的机器人强国之一，基础雄厚，技术先进。
讲到什么是机器人时，我们大多数人都看到过电影或书本里描绘的外形酷似人类的机器人，这是机器人的一种表现形式。
可机器人并不一定非得是这样的。
事实上，机器人的形状各式各样。
我们身边到处都有机器人。
机器人能够代替人类完成重复乏味或者危险的工作，提高我们的生活品质和工作效率。
机器人技术综合机械工程、电子工程、传感器应用、信息技术、数学、物理等多学科知识，代表着一个国家的高科技发展水平。
实际意义上的机器人，应该是“能自动工作的机器〞有的功能很简单，有的就复杂得多。
例如：家里的供暖系统，我们只需做最初设定接下来它就能自己工作，我们身边的大多数家用电器都是这样。
自动温控系统的元器件遍布于整座智能化大楼。

Period Four Grammar—The Present Perfect Passive Voice1．以上几句中所使用的时态和语态是现在完成时的被动语态。
2．现在完成时的被动语态的构成为：have/hasbeen＋过去分词。
现在完成时的被动语态表示到现在为止某事已经被完成或被做。
这种语法项目既要表示现在已经完成又要表示被动的含义，因此很多同学在具体运用当中容易顾此失彼，难以把握。
运用现在完成时的被动语态时应掌握以下几个问题：1．构成现在完成时的被动语态的构成为：have/hasbeen＋过去分词。
2．各种句式3.使用的场合(1)表示一个被动的动作发生在说话之前，强调对现在造成的影响或结果。
常与already，yet，never，recently等副词及时间状语sofar，bynow，uptill/tonow，since...，before...等连用。
Thousandsofmanmadesatelliteshavebeensentupintospacebymanycountries.许多国家已经发射了数千颗人造卫星到太空中。
Thedoctorhasn’tbeensentforyet.还没有派人去请医生。
(2)表示一个被动的动作或状态开始于过去，持续到现在，并可能持续下去，常与for或since引导的时间状语连用，或用于“Howlong...？”句型中。
Theimportantproblemhasbeendiscussedfornearlytwoweeks.那个重要的问题已经被讨论近两个星期了。
Howlonghasthemachinebeenused?这台机器使用多久了？Morethantenbridgeshavebeenbuiltovertheriverinthiscitysinceitsetupaneweconomiczone.自从这个城市建立了一个新经济开发区以来，这条河上已经建了十多座桥了。
4．现在完成时的被动语态应注意的几个问题(1)现在完成时的被动语态与一般过去时的被动语态的区别。
一般过去时的被动语态所表示的动作或状态与现在的情况没有联系，而现在完成时的被动语态则强调与现在的情况有联系。
Thebridgewasbuiltlastyear.这座桥是去年建成的。
Thebridgehasbeenbuilt.这座桥已经建好了。
(2)含有非延续性动词，如：borrow，finish，begin，buy，start，return，marry，open，join等的现在完成时的被动语态的肯定式不能与表示一段时间的状语连用。
若要表达相应的意思，则须改换动词或时态。
这本书买了多长时间了？误Howlonghasthisbookbeenbought?正Howlongagowasthisbookbought?但这类动词的现在完成时的被动语态的否定式，则可与since或for构成的时间状语连用。
Nobookshavebeenboughtsincelastweek.自上周以来，没有人来买书。
(3)短语动词是一个不可分割的整体，在被动语态中要保持完整性，其中的介词或副词不可省略。
Itissaidthattheproblemhasbeenlookedinto.据说已经调查了这个问题。
(4)只带有一个宾语的动词变为被动语态时，将主动语态的宾语变为被动语态的主语。
Wehavebuiltmanyhousesinthepasttenyears.→Manyhouseshavebeenbuiltinthepasttenyears.(5)带有双宾语的动词，如give，send，bring，take，teach，show，tell，make，sing，write，read，sell，buy，pay，lend，pass等，变为被动语态时，可将其中一个宾语变为主语，另一个保留不动。
