1.How to solve the housing problems in big cities With the development of the industry, more and more people are flowing into big cities.Some big cities in China are now enlarged with a rising population.Naturally, one of the most serious problems incurred is the problem of housing.Despite the mushrooming high buildings, the provision of living space still falls far short of demands.Since the world is advancing, people are no longer reconciled to living in shabby shelters.They look forward to decent dwelling places which show their dignity.Therefore, it is urgent that effective solutions should be called attention to.For one thing, the government is required to ensure that the housing system is well organized.It should perfect the system of housing accumulation fund and the housing financial system and strengthen the management of the real estate market.Another effective way to solute this problem is to build satellite cities around the big cities to lessen the housing burden of the big cities.This method has turned out to be practical in many big cities in the world.In a word, we have a long way to go.2.How to Keep Psychologically Healthy? One in four people will experience some kind of mental problem in the course of a year.When you fail to manage these problems, they are likely to cause various mental illnesses.The cause of mental health problems often vary a lot from one case to another.In today’s society, a good number of people are suffering from heavy pressure.Others lack communication skills.In addition, a lot of people are ignorant of psychological knowledge about how to keep mentally fit.There are a lot of ways to curb mental health problems and keep psychologically healthy.Firstly, find the real cause of your mental health problem and see whether you can do something about it.Secondly, learn to relax yourself and take exercises to release the pressure.Lastly, you may find it helpful to talk to your partner or friend about your problem, or seek support and advice form a psychological consultant

3.Credit Cards Personal credit cards are becoming more common in China.Banks and other financial institutions are encouraging their customers to change the way they buy things.Credit cards, otherwise known as “plastic money”, are being offered on very good terms to encourage the change.Consumers will be able to “buy now, pay later”, and many see this as an advantage.作文答案

But people need to be careful.There are dangers associated with credit cards.Some people find it very easy to exceed their budget.They are tempted to purchase goods that they do not really need, and can become quickly overburdened by debt.The credit cards often charge a high rate of interest, which exacerbates the problems for these people.However, used wisely credit cards can improve the quality of people’s lives.They can give people access to money to meet sudden unplanned expenses.Properly handled, they can let people control their expenditure and the monthly statements provide a record of where their money has gone.The Way to Success “Genius is one percent inspiration and ninety-nine percent perspiration.” And here comes our question, what is the way to success? A strong will and great efforts are the most essential two keys to the door of success.Why do people fail to achieve their goal? The reason is that most of them give up halfway due to their lack of a strong will once they encounter any difficulty.A man of a strong will always sticks to his cause no matter how tough it might be.Would Thomas Edison be such a great man in history if he had done nothing but possessing a strong will? We are all familiar with his story that he had tried one thousand kinds of materials before he finally made his great bulb light up.Without hard effort, Edison might have been a nobody.Without efforts, no one can succeed.To sum up, a strong will and great efforts can help one open up the way to success.Where there is a will with efforts, there is a way.5.A low-carbon Lifestyle Nowadays, there are a considerable number of individuals who prefer to lead a low-carbon lifestyle which find expression in the fact that more and more commuters are using public transportation system in their daily life.Low carbon lifestyle can endow us and our society with numerous benefits.Firstly, it goes beyond doubt that low carbon lifestyle contributes a lot to the environmental protection and it is a favorable way to slow down the rate of climate change of our earth, which also means a lot to our health.We are supposed to undertake the responsibility to lead a low-carbon lifestyle, which is of great significance.And there is a diversity of measures we can take so as to lead such an environmental-friendly life.For one thing, we are expected to minimize the use of private cars, which emit a large amount of greenhouse gases.For another, we are supposed to cultivate the public awareness of energy conservation for energy in the world today is decreasing rapidly.For instance, we can turn off electrical appliances if not necessary as well as using renewable

作文答案

materials.Furthermore, at our leisure, we can seek opportunities to plant more trees which can absorb carbon-dioxide.In brief, low-carbon lifestyle is nothing but the best choice for us and only in this way can we form a harmonious relationship with the environment.6.A Boom in Continuing Education From the graph, we can learn the number of continuing education participants has kept increasing from 1992 to 2007 in X city.In 1992 there were only 20 thousand people taking part in the continuing education, but in 1995 the number grew to 60 thousand, and in 2000 140, and by 2007, the number has reached 210 thousand.It can be seen easily that continuing education is gaining more and more popularity.The following reasons are responsible for this boom in continuing education.Firstly, during the work many people begin to realize what they have learned in schools is far from enough.So they turn to continuing education to gain more knowledge and skills.Moreover, as the science and technology in China are developing very fast, adults after graduation have to refresh themselves.In addition, in modern society, those without bachelor’s degrees or above are less competitive.As far as I am concerned, the boom in continuing education is a necessity.It provides those on-the-job people with chances to get advanced degrees and gain more knowledge.As our society develops, more and more people will receive continuing education in the future.7.A Job earching Experience

Last Friday my English teacher told me that one of her friends was looking for an English governess.I asked for her friend name and phone number and determined to seize the chance.I was a little bit nervous when I went to the woman house.I was told that the talk between us that day would decide whether I could take the job.However, when the woman, Lucy as she was called, welcomed me into her house, I felt much relaxed.I thought as long as I was sincere and friendly I would perform well.The conversation went on smoothly.She seemed much more interested in my habits and hobbies than how good I was at English.Then it seemed that I did the most talking that day.I told her about my family and school life.Obviously I succeeded and from then on I went to teach her English every weekend.Lucy told me later that it was my sincerity that makes her willingly accept me.It is true that there are many tips while seeking for a job, but remember to be sincere.It the secret of my success.作文答案

8.A Letter to the University President Dear Sir，I am writing to put up some suggestions concerning our teaching and campus life.As a sophomore from the Math Department, I am quite satisfied with the present condition of my university, but I餯 like to say that there is still some room for improvement.First, I believe that more attention should be paid to the guidance of our study methods.To some extent, university students are capable of studying by themselves, but more often than never, we find ourselves at a loss as to choose good books to read and appropriate topics for our research.It is clear that we need some advice from our teachers.If our teachers can lecture more on “how to learn by yourself” for us, especially for the freshmen, our skills will be further improved.Second, more activities should be conducted to make our campus life more colorful.I am sorry to say that the present life on campus is quite boring.Every day we have classes, read in the library, or stay in the dormitory.Life here is routine.We need more meaningful activities organized to enrich our college life and enable us to study more efficiently.I hope you can consider my suggestions.Thank you.Yours sincerely

They say “mind breeds physiognomy”, which implies the importance of one’s appearance.Similarly, a correct and neat spelling of a composition can not only reflect a success of the composition but embody the decent disposition of the writer as well.Unfortunately , a great number of students pay little attention to their spelling though their composition turns out quite good either in content or in logic, thus leaving the teacher in a dilemma whether to give a high score or not.Tracing the reasons hidden behind, we can easily find it is mainly because some students are unaware of the importance of the spelling.In their minds, the content absolutely outweighs the form so the attention to spelling can be pleasantly spared.Objectively speaking, in the examination, the limited time and urgent situation make students have no more effort to care about their spelling and the fact is that they have to write as quickly as possible to finish it on time, leaving some characters vague or incorrect.Just as is said above, spelling, in a sense , mirrors the content, so a direct result of the bad spelling is the low academic score in the exam for it is hard to expect a text full of undistinguishable words toreceive a good appreciation.Further, once the habit of lax spelling was formed, in a long run the quality of being negligence could also be gradually shaped, which would undoubtedly exert negative impact for our future work and life.听力

参考范文： We Shouldn't Totally Turn to the Internet

Nowadays, Internet has become an indispensable part in our life, and we use it for various purposes, such as searching useful information and chatting online.However, now more and more people turn to the Internet for help whenever they have trouble in finding solutions to their problems, and this phenomenon has aroused the public's attention.Relying on the Internet to solve all our difficulties can have bad impacts on us.On one hand, since we can always settle the troubles by searching solutions online, we can become very lazy and don't bother to think up answers by ourselves, which can hinder the development of creative thinking.On the other hand, the answers online may be inaccurate or wrong.If we use them without thinking the credibility of them, we may make serious mistakes someday.As far as I'm concerned, we shouldn't completely depend on the Internet to settle problems.When we come across some difficulties, we’d better try our best to find possible solutions.If we make great efforts and still can't come up with an answer, then we can surf online to search solutions.But we should question the correctness of these answers before we adopt them.
