Some parents even believe that trying to solve hard math problems will promote the growth of childrens brains and help develop their logical reasoning

By going through the text and the notes, they can remember important information.4. How to prevent students cheating in

15、 examinations?First, the administrators must adopt severe measures to punish that disgraceful practice. In the case of serious offenders, it is not enough just to give them an F.

16、e university rules strictly. When they see students cheating, they should not turn a blind eye to it.Unit3：1.What do you think are the things that contribute to a successful marriage?The success of a marriage is due to many factors, of which love is obviously the most important one. Other factors, w

17、hich are not entirely unrelated to love, include shared values and interests, mutual understanding, commitment, effective communication, similar educational background, equal economic status, physical fitness, etc. With the same values and moral standards, friends may develop into lifelong partners.

18、 After marriage, there needs to be a commitment to one another, and to the well-being and development of the family. Similar educational background and intelligence levels are also considered important by some people. They believe that only with mutual appreciation and understanding, can the couple

19、get along easily and happily.2. Why do people get divorced? Can you guess some of the reasons?Sometimes it is because the couple did not really understand each other before the marriage, as love was blind at that time. After marriage, they see each others shortcomings more clearly. When disappointme

20、nt grows beyond control, divorce becomes inevitable. Sometimes it is because one of the couple has changed after the marriage. For example, after the husband is promoted to a leading position, he may have a hectic time all year round, with hardly any time left to be with his wife. Sometimes one of t

21、he couple has lost his or her job and becomes irritable. Due to the continual quarrelling at home, the family breaks up.3. What do you think of the lives of single mothers?Most people look upon single mothers with sympathy. Single mothers have to support their children on their own. They may find it

22、 difficult to provide their children with all the luxuries children of two-parent families enjoy. Worse still, they may be under great psychological pressure. Moreover, their children may develop a sense of inferiority. When they see other children are bathed in the love of both parents, they may fe

23、el bitterly disappointed.4. What is your view of the fact that the wifes housekeeping duties remain the same even when she works outside? What could be the solution?If the wife works during the day just like the husband, then it is obviously unfair for the wife to shoulder all the housekeeping dutie

24、s. If the husband can share the household chores with the wife, the love between them can be strengthened. Unfortunately, influenced by tradition, many men are unwilling to do housework, thinking it to be unmanly. If we want to change the situation, the media had better give more publicity to model

25、husbands who assume a large part of those duties. Gradually, people may change their image of a husband who constantly sits in front of the TV, watching football games or international news. Also, the development of modern technology and the appearance of more modern conveniences will further lighte

26、n the housekeeping burden. Thus the problem of who should do the housework will become less important.Unit4：1.What do you think people will choose: a low-paid job one likes, or a boring well-paid job?I think many people prefer to find a job that they really like. After all, most people want to enjoy

27、 themselves rather than have plenty of money without a sense of achievement and happiness. On the other hand, some people may choose a well-paid job instead of a job close to their heart to earn more money. If one is in serious financial difficulty, one can hardly afford the luxury of a dream job. M

28、oney is the top priority.2. Do you think ones character is important in finding a job? Why or why not?I think it is. Although many employers lay emphasis on candidates educational background and work experience, some believe that candidates character is equally important for a successful career. In

29、contemporary society, many projects are so large that they require the coordination of a group of people rather than a single persons effort. Therefore, a good team player is often welcomed. Professionally skilled people may not be able to accomplish a large project if they are easily angered and ca

30、nnot get along with their colleagues. If you want to assume a leading position, you should be firm on important issues while allowing your subordinates plenty of freedom. In fact, it is becoming increasingly common for companies to test candidates EQ (emotional quotient) before they decide to hire t

31、hem.3. What courses are useful for ones job?In fact all courses may turn out to be useful in our future careers. The basic courses we take in the first two years of university lay a solid foundation for our future development. In the case of computer majors, for example, the math they have learned w

32、ill enhance their ability for logical reasoning. The English courses they have followed will help them read the literature in their fields with greater ease. Art courses may increase their sense of balance and beauty. However, the courses in their specialties are often of greater relevance and value

33、 for their career development. For instance, computer majors may find courses such as programming, computer network, database, and CAD (Computer Aided Design) more closely related to their future work.4. What questions do you think are often asked in an interview? Why are they asked?To start with, t

34、he interviewers may ask you about your education. In this way they can gather information to see if you have acquired the basic knowledge required for the job you are applying for. Perhaps most of them will ask you about your work experience in this field to see if you have the necessary skills for

35、the job you have in mind. Usually employers do not like an entirely inexperienced employee. They may also ask about your character, weaknesses and strengths to find out what kind of person you are. They may even ask you something that is not directly related to the job in question. Your answers tend

36、 to show your intelligence level and communication skills.Unit 5：1.Do you want to be a boss who is starting a company or an employee with a high salary?Different people may have different choices. Some people may put a regular job above good pay for a variety of reasons. Employees usually know what

37、they are supposed to do and have a fairly stable life. With a high-paying job, they and their families can live a comfortable life. When they have accumulated enough money, they can start a business when conditions are favorable. On the other hand, many people want to set up a business of their own

38、right now. Indeed, launching a company involves a lot of effort. What is worse, there is risk. But they like challenges. By trying to establish a company, not only may they make lots of money, they can also develop their abilities to overcome difficulties.2. What kind of boss would you like to work

39、for: one who is inefficient but kind, or one who is efficient but very strict with employees?Many people, if not most, prefer to work for a kind, good-natured boss. Under such a boss, they feel secure and happy. The boss wont scold employees simply because they have made a small mistake. He will als

40、o be generous. It is true that sometimes because of his lack of ability, his company may not reap huge profits, and employees can hardly get a raise. But happiness is surely more important than money. However, some people, including me, will choose to work for a boss who is capable but very strict w

41、ith his subordinates. If the boss is capable, he will lead the company to one new height after another. When the company thrives, all employees will benefit. Even if the boss may give an employee a severe dressing-down for something he or she did, the employee can learn a lesson from the event. Unde

42、r such a boss, employees can gain valuable experience, which may serve as a good foundation for them to start a business of their own in the future.3. Why do some people think sports clothes and shoes provide a good business opportunity? What age groups do you think the business people should target

43、? Why?With more leisure time and money, many people pay more attention to their health and recreation. As a result, more and more people will engage in sports, and they will buy more fitness gear, including sports clothes and shoes. Obviously this provides a hot business opportunity. In my opinion,

44、business people should target young people first. They are active and participate more in sports than other age groups. But business people should not neglect older people. After retirement, they often find their health on the decline, and therefore have the motivation for fitness exercises. As for

45、middle-aged people, many of them are under such great pressure at work that they can hardly afford the time for sports.4. If you wanted to start a business, which factors would you consider: your education and ability, your money, or the market? Why?If I wanted to launch a business, I would consider

46、 all of these factors, for they all play an indispensable role. First of all, I would consider my ability. Since I majored in biology, I would be cautious in starting a company to sell something I am not familiar with such as building materials or DVDs. With my educational background, I may find it

47、easier to run a company selling bio-tech products. The next thing I would have to take into account, is the money available. Suppose the establishment of a company required a capital of a million dollars, I would try to see whether I could get a loan. If not, I would give up the idea and try to set

48、up a smaller service company that required less capital. Last but not least, I would survey the market to see if the products I planned to deal with could be sold. If they were unmarketable, I had better give up the idea of founding a company in this area. If they sold well, then I would go ahead.Un

49、it 6：1.Why do you think some people smoke? What are the disadvantages of smoking? Some people think smoking makes them relax. Some people smoke just because all those around them smoke. Some believe that by passing cigarettes around, it will be easier for them to start a friendship. Others claim tha

50、t smoking is a precondition for a booming tobacco industry, which in turn ensures a large tax income for the state. But I think those reasons, if we can call them reasons, are insignificant compared with the harm smoking brings. Smoking is harmful to ones health. It can lead to many diseases. Long-t

51、erm smoking may result in lung disease, or even lung cancer. Also, some heavy smokers may suffer from breathing difficulty, high blood pressure, heart trouble, amongst other diseases. It has been proved that even non-smokers who breathe in the smoke can develop health problems. Moreover, cigarettes

52、cost money. Some chain smokers consume two packs of cigarettes a day. This can be an unnecessary financial burden on a family that is not rich.2.What do you think can be done to improve older peoples lives if their children do not live with them? First of all, children should visit their parents fro

53、m time to time. This is a sign al of concern, which can be a great comfort to them. Even if people are terribly busy under the pressure of work, they can at least call their parents to say hello. Furthermore, children should provide their parents with what they need. If elder o lder people can get m

54、oney or other supplies on a regular basis, they may get a sense of security. Also, the government should establish more homes and organize more activities to meet the increasing needs of an aging population.If some elder o lder people prefer to live at home, they should hire caregivers. In the light

55、 of their shortage of money, an expert has proposed a system under which aged people can mortgage (抵押) their apartments to the bank in exchange for a monthly income. By the time they pass away, the apartments belong to the bank. But at least the old people do enjoy a decent life while they are alive

56、.3.Why do some people become alcoholics? How can they solve their drinking problems? Some people drink because their parents drink a lot, so they follow suit. Some people pick up the habit of drinking because they feel lonely or bored, others drink when they are sad or angry, and still others drink

57、to celebrate happy occasions. Gradually, they drink more and more until they are hooked on alcohol. To solve drinking problems, people should be informed about the dangers of too much alcohol consumption, such as high blood pressure, heart disease, liver trouble, and so on. It is also reported that

58、alcohol can damage brain cells and memory. Under the influence of alcohol, one can hardly concentrate or think deeply, so their work efficiency drops. Worse still, drunks often cause traffic accidents or resort to physical violence. Moreover, one must have strong willpower to give up drinking. But u

59、nfortunately, few people are strong-willed enough to defeat alcoholism on their own. Often, they need external help from parents, spouses, friends, doctors or an organization like Alcoholics Anonymous. 4.What should be done to help unemployed people? Before unemployed people find a new job, their basic living standard should be met. They need subsidies (補(bǔ)助金) from the government to maintain live a normal life, wh
