    Directions: In this section, you are asked to write a composition with the title “The Biggest Dream of My Life.” You should write at least 120 words and cover the following points. 

    1. What is your biggest dream?  2. Why do you have it? For how long have you got it? 3. What are your plans to achieve your dream?


    参考答案:

    The Biggest Dream of My Life I know many people whose biggest dreams are things such as what career they want to get into, how much money they can earn. My dream is nothing like that. My biggest dream has always been and will always be to travel around the world. I have one life here on Earth, so I don’t want to die regretting that I didn’t see it all. Actually I have had this dream ever since I was in primary school. In one geography class, when the teacher presented us the globe and national fl ags of various nations, I thought I found the dream in the depth of my heart. And the moment I came to college, I had always envisioned myself of becoming a nomad. I would roam around the world. No permanent address. Any place can be my home and I am home within myself. Meanwhile, I am aware that it’s really a costly dream. The first step I need to take is to begin to save money to support it. And I think it’s a good idea to start exploration from my hometown and the city where my university is located. Just as a saying goes: a big dream begins with the first step.

    How should language rules be learned according to the Direct Method?
    Language rules are learned inductively through listening and speaking activities. The teacher sets up a few carefully chosen illustrations of a rule and leads the students to discover the relationship of the new elements to others previously learned. Students work out the rule governing those examples. In other words, students have to induce grammatical rules from examples in the text. A language could best be learned by being used actively in the classroom.

    问答题
    Many people hold the view that money is everything. What do you think? Write a composition of 400 words on the following topic, expressing your views on the importance of money. HOW IMPORTANT IS MONEY?  In the first part of your writing you should present your thesis statement, and in the second part you should support the thesis statement with appropriate details. In the last part you should bring what you have written to a natural conclusion or a summary.  Marks will be awarded for content, organization, grammar and appropriateness. Failure to follow the above instructions may result in a loss of marks.

    正确答案:
    HOW IMPORTANT IS MONEY? No one would deny that money is unimportant. There are certain things that human beings need—food, shelter, perhaps medical care—and these things cost money. But if one has enough money to live on, to pay for the basic essentials of life, is it important to have a lot more money than that? Will your life improve in proportion to the amount of money that you have? Money is important but it does not guarantee happiness.
    There is no denying that money can buy a lot. Maybe you do not need much money to pay for simple shelter, but how about if you want a nice, big apartment in a nice neighborhood, or if you want to buy a house? The fact is that people do get on each other's nerves if they are crowded together in a small space, and that a married couple or members of a family are likely to get along better if they are not constantly tripping over each other and asking each other not to be so noisy—if each can find a little privacy from time to time. A big apartment or a house will allow them this privacy.
    It is nice to get a little pleasure out of life, a little fun from time to time. Unfortunately, many of the fun things that you can do today cost money. Films, concerts, gyms are available to you only after you have bought the tickets. Delicious food in a restaurant can only be tasted after you have paid for it. Some people believe America is the most fantastic place in the world, while some say it is the hell. Why do their opinions vary so greatly? Because the latter do not have enough money to take advantage of many attractions there.
    However, is money the road to happiness? Not really. Large number of people work every day, work overtime, work weekends, and make a lot of money. Are they happy?. No. They have no time to form or to maintain friendships. Enjoying means taking things in, taking the time to see, to hear. But unfortunately, many people simply do not take the time to do these.
    Surely everyone has thought at times, ff only I had a lot of money, I could be the happiest person in the world. It is important to remember, however, that money is only a means to an end, not the end itself.

    How should a person rest during an illness?He should rest both his body and ____.

    正确答案: his mind
    解析:
    细节题。题目问的是病人生病期间应该如何休息。由听力原文中“During an illness, it’s wise not only to rest your body but also to rest your mind.”可知,病人不仅要放松身体,还要让大脑休息好,这里填his mind。
    【录音原文】
      When you’re quite sick, your doctor generally advises you to stay in bed. But it’s not always easy to do so. You have your work to do. The stress of your job will often keep you working long after you should have gone to bed. Generally, following the doctor’s orders isn’t just limited to bed rest. You should also pay close attention to how you take your medicine. Medicines will do you little good if they are not taken properly. In fact, many medicines can be dangerous, if not taken exactly according to the instructions. During an illness, it’s wise not only to rest your body but also to rest your mind. Give yourself a complete rest, both physically and mentally. Free your mind from worries and just relax.
    Q11: What does your doctor usually advise you to do when you’re quite sick?
    Q12: What does the speaker think of following a doctor’s advice?
    Q13: What will keep a sick man working when he should have gone to bed?
    Q14: What will happen to the person who doesn’t take medicines properly?
    Q15: How should a person rest during an illness?
