Keys to Task ExtensionsUnit1Task6:Extensions6.1(for reference only)IntroductionThe purpose of this project is to find out the real situation in which the students in a particular college spend their time surfing Internet.It includes how much time they spend doing so,for what reason they work with Internet,and what impact it has on students’learning.To find out the facts about Internet,a survey will be conducted among the students,teachers,and administrative staff.The main proposed problems related to Internet at most colleges can be the overuse of it and overspending of time on it.The serious impact resulted from overdoing Internet needs to be discovered in this project.At most colleges in China,one policy is that freshmen are not allowed to possess a computer,and there are some limitations for them to surf online,which is regarded as one kind of protection to them.In this way,they will not be easily exposed to unhealthy films,pictures,or essays.Also,they can spend not so much time on it and their study will not be affected.In the information society, it is necessary to get information quickly.One of the main sources is Internet.Therefore,it would be wiser to let college students make use of Internet and offer them some guidance.Main bodyFor senior college students,overuse of Internet has become a serious problem.Some students stay up very late surfing the lnternet.Some play video games,some do a lot of chatting,and some spend more time watching films.One student said that on average he spent five hours a day surfing the lnternet.Due to the large number of hours spent on Internet,some students have,to some extent,ruined their academic study and their health.At present,the policy is flexible to the senior students at some colleges.To reserve Internet use, it would be wise for the college to set up an appropriate policy on the one hand and carry out education on the other.It will be important to let students know the passive effect the overuse of Internet might bring to them.At the same time,some rules should be set up.For example,there could be a limit on the use of Internet:after11p.m.no students are expected to surf online.ConclusionTo sum up,it is imperative for college students to obtain information they need for their academic learning through Internet,and it is also necessary to let the students know the bad impact the overuse of Internet would cause on their study and health.6.2(for reference only)IntroductionThe purpose of this project is to find out the main reasons why some families like to send their teenagers to study abroad,and what problems might be brought about to these families and the children.Several articles in various newspapers reported that it had become a social phenomenon for parents to send their children abroad to study.This phenomenon has drawn much public attention.For some families,it has become a big financial burden,and some teenagers could not manage to study and live independently in a foreign country.The project is trying to expose a real picture about it and see how serious problems it might bring about.The project will also try to search for a better policy to help solve this problem.Keys to Task ExtensionsMain bodyIn accordance with the statistics and information gathered from various newspapers and the Internet,it has become a rather serious problem for some families in China.They sent their children to study abroad because of the following two reasons.First,some of these families are rich enough to do so and they want their children to receive better education abroad,especially language training.Second,some families thought that their children couldn’t pass the national university entrance examinations.So they sent their children abroad.For the latter reason,some families are financially not able to do so.They have to borrow money to pay for their children’s education fee abroad.As a result,some of the families ran into heavy debt.These parents can’t live a proper life because they have to send most of their earning to their children.For some children who are studying abroad,they can’t manage to live and study on their own well.As they are rather young,they can’t budget their time and money well without their parents’help.Therefore,they also run into trouble.It is necessary to tell the parents about the real problems children may have in a foreign country.It is also necessary for them to know that there is a possibility for their children to receive good education at home as the enrollment of college students has already been expanded.And the middle school students have more choice than before for their further education.For these families,it will be much wiser to consider their financial competence as to whether they will be able to bear it or not.Therefore,it is very necessary to take everything into a careful consideration before they make a final decision.ConclusionFor some well-off families with independent children,it is a good idea to send the children to study abroad.For other families,it might be wiser to let their children study at home,because their children can also receive a proper education.6.3IntroductionOver the past25years,British society has changed a great deal,but the attitudes about working-class or middle-class has not changed much.Main bodyWorking-class refers to those who do manual work.They were paid less than middle-class people.The stereotype of those people is one who would give his wife“housekeeping”,and then would go out and spend the rest on beer,smoking and betting.Nowadays,factory workers earn as much as their middle-class supervisors.Working-class people seem to be losing the feeling of inferiority.ConclusionAmong the young people the attitudes about the working-class or middle-class have changed a lot,but among the older generation the stereotyped attitudes toward working-class still exist.Unit2Task10:Extensions10.1(for reference only)I do agree with the statement that private cars should not be encouraged in big cities in China.The following examples can support my view.One example is that ten years ago it was a very quiet and smooth street in front of our house.But now it has become very crowded from morning till night.There are too many cars in the street.In the past it took only twenty minutes to get to my office,but now it takes at least forty minutes.Another example is that my neighbour bought a car and he got seriously injured several days ago.His family was shocked and very much depressed.To further support my view,I’d like to cite one more example.Due to the exhausted gas produced by the large number of cars,air in our city is not as clean as before.Some experts say that air pollution has become one of the biggest problems in our city.For what is mentioned above,I think that the government should not encourage people to buy cars blindly.10.2(for reference only)This table shows the average family income and expenses in a Chinese city in1985and1995.In 1985,the average family income was¥400,and in1995,the income was over six times as much as that in1985.In1985,the average family income was divided in the following way:65%was spent on food,5%on housing,10%on entertainment,10%was saved,and10%was used to meet other expenses.In1995,a slightly different picture emerged.Housing cost increased by5%,food cost decreased by15%,and entertainment went up to20%,and the savings and others remained unchanged.From this table,we can see that the people in this city earned more money in1995than in1985, and spent more on entertainment,which indicates that the people in this city wanted to enjoy themselves.In conclusion,a big change has taken place in the life of Chinese people and their living standards have been improved.10.3(for reference only)This article shows the danger of nuclear weapons to the human beings.This danger is increasing every day because nuclear weapons are possessed by more countries and they are very accurate and powerful.If there were a small accident,a nuclear war would break out.10.4This article shows that people are rejected sometimes just because they make mistakes in their resumes.The author believes that we’ll get rewarded by doing little thinys well.Keys to Task ExtensionsUnit3Task10:Extensions10.11.Topic:AIDS Infection2.Title:Sharp Rise in AIDS Infection in the Developing World3.Introduction:The World Health Organization report indicates that cases of AIDS infection areincreasing rapidly in developing countries particularly in Asia,Latin America,and Sub-Saharan Africa.Currently,the virus has infected8to10million people.The infection rate in developed countries is not increasing as rapidly as it had been,but the dramatic increase in other parts of the world indicates that AIDS cases will continue to rise in rural areas of the Third World.4.Main body:The estimate about the cases of AIDS is consistent with an earlier projection by theorganization.But there is a sharp increase in Asia,Latin America,and Sub-Saharan Africa.The increases reflect the growing heterosexual transmission of the AIDS virus around the world.The new estimates about AIDS cases are based on a recently completed analysis of blood tests.The analysis showed that the rate of HIV infection is slowing in industrialized countries.But in sub-Saharan Africa,cases of HIV infection have increased at a rapid speed.Date from Southern Asia, including Thailand and India,showed marked increases in HIV infection.5.Conclusion:The cases of AIDS virus in the developing countries will continue to increase and thesepeople are in danger.10.2DESCRIPTIVE ABOUT HOW PAPER IS MADEPaper is made from wood,and many of the world’s paper mills are found in those countries that have great forests----Canada,Sweden and Finland.Paper is made in the following procedure.After the trees are felled or cut down,they are transported to the sawmill,where they are sawn into logs.Conveyed to the paper mill,the logs are placed in the shredder and cut into small chips.These small chips are mixed with water and acid before they are heated and crushed to a heavy pulp.Cleaned and chemically bleached to whiten,the pulp is passed through rollers to be flattened.When the pressed sheets are dried and refined,the paper is produced.10.31)Brown,H.D.2000.Principles of

student is encouraged to put down as many topics of interest as possible.By discussing their possibilities as a subject for research,the students should help each other to decide whether the topic is too vague or too broad,too narrow or too complicated;whether there are sufficient available resources that will help finish this project.6.2Students should be clear in their minds what their own ideas on this subject are.The teacher can ask the whole class to brainstorm the possible arguments which will help them develop their project.6.3•What is the credit system in China like now?•What are the

economic power against private management and the government to achieve their goals.These goals are primarily higher wages,better working conditions,and job security.(Scott and Nigro,1982)(2)Language acquisition device:Language acquisition device(LAD)refers to the capacity toacquire one’s first language,when this capacity is pictured as a sort of mechanism or apparatus.In the1960s and1970s Chomsky and others claimed that every normal human being was born with a LAD.The LAD included basic knowledge about the nature and structure of human language.The LAD was offered as an explanation of why children develop competence in their first language in a relatively short time,merely by being exposed to it.(Longman Dictionary of Applied Linguistics)(3)Acrophobia:Acrophobia is an intense,unreasonable fear of high places.People withacrophobia exhibit physical symptoms in response to being at great heights.One sufferer from extreme acrophoia,Tom Smith,is unable to go above the third floor of any building without feeling enormous anxiety.(4)Boycott:A boycott is an organised refusal by a group of people to deal with another personor group to achieve a specific goal.An illustration is the famous boycott that began in1955when Mrs.Rosa Parks of Montgomery,Alabama,refused to obey a local ordinance requiring black people to sit at the back of city buses.Mrs.Parks was arrested,and that sparked off a boycott of the Montgomery bus system by blacks.Keys to Task Extensionsunit7Task7:Extensions7.11.400,0002.3,6003.more than804.no more than100,000/less

clearly seen that the rate of smoking for both men and women is currently declining and that fewer women have smoked throughout the period.In1960,600men in every1,000was smoking.This number decreased gradually to500by1975and continued to decrease but more steeply to250in2000.In contrast,the rate of smoking in women in 1960was very low at only80in every1,000.By1968this increased to170,and increased again but more steeply to320in1977.The rate of female smokers then remained stable at320until1984at which point the figures began to decline and had dropped to200by2000.In conclusion we can see that the rate of smoking in men dropped throughout the whole period but was always at a higher level than the female figures.The rate of smoking in women increased until1977 but then decreased for the rest of the period.Unit8Task6:Extensions6.1(for reference only)The optimum positioning of roadside advertisements is recognized by the industry as an important factor in attracting the attention of passing drivers.Less acknowledged is the possibility that the location of an advertisement may distract attention from vital driving-related information.This study compared street-level advertisements(SLAs)with raised-level advertisements(RLAs)of the same size that were suspended3m above the ground,on their ability to attract attention under different task conditions.Participants were split into two groups and watched video clips of driving,rating them for hazardousness while their eye movements were recorded.One of the groups was additionally primed to attend to advertisements.SLAs received the most fixations when participants were solely looking for hazards,and the fewest fixations when primed to look for advertisements.Though SLAs also had longer fixations than the RLAs,they were more poorly recognized in a subsequent memory test.We conclude that SLAs attract and hold attention at inappropriate times compared to raised-level advertisements.6.2(for reference only)This study compared street-level advertisements(SLAs)with raised-level advertisements(RLAs)of the same size that were suspended3m above the ground,on their ability to attract attention
