Good afternoon, ladies and gentlemen. My topic is “____________”.
Now in the 21st century, advertising is more and more important for people. Why?
I think it is because through advertising, people, especially the businessmen, can introduce their products to the people all over the world. Because of this, many companies spend a lot of money on advertising. As we all know, there are many advertisements which are very interesting and popular. For example, Michael Jordan made an interesting advertisement for Nike. From this you can see how the companies make their products known to the world.
People can make a lot of money through advertising. It is known that many famous singers and movie stars make money in this way. However, I don’t think this is a good way for them to make money, because they are not the professional（职业的）advertisers, especially those who advertise in medicine advertisements.
Nowadays, advertising not only means making the products known, but also means making ourselves known to people around us. Living today, we have to make people believe in us if we want to do important jobs. But how can this be done? We should first let other people know our good side: the good habits and abilities we have. In short, we should always remember to advertise ourselves to others. As I said before, advertising is not only important for companies but also for everyone, for all human beings. This is the most interesting thing about advertising.
33. The best topic to fill in the line in the first paragraph is “____________”.
A. The Importance of Advertising
B. Making Money through Advertising
C. Advertising Ourselves
D. Advice on Advertisements
34. This passage may be a（an）____________.
A. advertisement
B. story
C. speech
D. report
35. According to the passage, which of the following is NOT right?
A. Many companies are willing to spend money on advertising.
B. Advertising can make some people rich.
C. People can introduce their products through advertisements.
D. Advertising is not necessary for anyone.
36. What does the writer think of the advertisement made by Michael Jordan?
A. He thinks it helps to introduce the product.
B. He thinks it is right for him to make money. 星沙英语 https://www.360docs.net/doc/9d16178849.html,
C. He thinks it costs too much money.
D. He thinks Michael Jordan is a professional advertiser.

One terribly cold day, a snowstorm hit our area. Needing firewood, I quickly set out with my best friend, Bruce, to look for a tree to cut down. Cutting down a tree in a snowstorm can be dangerous. So it was important to have a friend who could warn me of dangers.
When I chose a big 23-meter-tall tree and prepared to cut it down, Bruce suddenly warned me, “Don’t cut down that tree! It’s too close to the power line!” I wasn’t sure about it. So I decided to disregard his warning. I couldn’t wait to finish the job and go back home. I began cutting down the tree. When the tree fell, there was no longer any doubt whether my friend was right.
The tree caught the power line, bringing it to the ground. I considered cutting the tree off the line. After all, electricity can’t travel through wood. As I reached out my finger to touch the tree, pain ran up my arm and through my head. I had been shocked!
After I returned home and told my mother what happened, she quickly called the power company. Workers from the power company soon arrived. One of them asked if I had touched the tree, and when I told him I had, his face turned pale. “You should have been killed,” he said. It was my boots that saved my life.
Within two hours, the workers removed the tree. Soon the snowstorm calmed down ——but not my mother. Even though she was glad that I wasn’t hurt, m y mother was still serious with me. After all（毕竟）, I shouldn’t have brushed off my friend’s warning.
37. Although Bruce warned him, the writer still cut the tree down because
____________.
A. he was sure there would be nothing to happen
B. he wasn’t sure if Bruce was right and expected to go home earlier
C. he didn’t hear his friend’s warning at all because of the blowing wind
D. he knew electricity can’t travel through wood
38. The underlined phrase “brushed off” in the last paragraph may mean “____________”.
A. pay no attention to
B. give up
C. think over
D. give in
39. Which of the following statements is NOT true according to the passage?
A. Without his boots, the writer would have been killed by electricity.
B. The writer’s mother was angry wit h what he had done.
C. When the tree was cut down, the writer realized his friend was right.
D. When the tree caught the power line, Bruce called the power company.
40. In the passage, the writer mainly wanted to tell us ____________.
A. one of his terrible experiences when cutting down a tree
B. not to cut trees down any more to prevent dangers from happening
C. it’s important to listen to other people’s opinions
D. to be careful while we’re working with friends

阅读下列短文，根据短文中的信息完成文后表格。（每空一词）
Have you had a headache during a test? Have you ever been so worried about something that you have a headache or even can’t sleep at night? If so, then you know what stress is. Stress is what you feel when you are worried about something. This worry in your mind can make your body feel bad. You may feel angry, sad, scared, or afraid——all of which can give you a stomachache or a headache.
However, there are different kinds of stress. Some kinds of stress are good and others are bad. Good stress might happen when you’re called to answer questions in class or when you have to give a speech. This kind of stress can help you to get things better done. For example, you may do a better job on your test if the stress pushes you to prepare better before the test.
On the other hand, bad stress can happen if the stress lasts too long. You may not feel well if your parents are fighting, if a family member is sick, if you’re having problems at school, or if anything else makes you unhappy every day. That kind of stress isn’t going to help you. And it can actually make you sick.
The best way to fight the stress is to have a balanced life. Make sure you keep your SELF in mind: Sleep, Exercise, Leisure（休闲）, and Food. If you get enough sleep and ea t properly, and if you exercise and leave time for fun, you’ll probably

Although most students would be unhappy if they found that they had f 63 the math tests, they have learned a lot about themselves. They know they might not become great engineers or physical scientists. So failing can help a student to live a much h 64 life if he or she draws the right conclusion from the failing. They may then decide on their goal and c 65 the kind of work they would like to do.
It is impossible to decide whether or not you like something u 66 you have tried it. If you decide that you would like to play the violin, you need to take more than one lesson before you can know whether you have any i 67 or ability.
However, it’s not enough to want to be a great violinist. You a 68 have to like the hard and long training before you become one. If you would enjoy being a great violinist but h 69 the hard work, forget it.
