题型：不详难度：来源：
Stop. Listen! What do you hear? You may hear many different sounds. Some of those sounds may be noise. Noise is a loud or unwanted sound.
Noise can be caused by many kinds of machines, such as motorcycles, jet planes, farm tractors(拖拉机), rock music is also noise.
What happens to people who live near noisy machines or use them over a period of time? Doctors have found that these people have trouble in sleeping. But, most important, constant(不断的) loud noise can cause a loss of hearing.
Scientists use a unit of measure called decibel(分贝) to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands can measure over 120 decibels. Noise at this high level(层次) causes the great hearing loss.

举一反三
（A）
We all have our own ways of sharing our life experiences with others.
Photographers use cameras, artists use brushes, musicians use songs and writers use stories.
Spencer Johnson’s story Who Moved My Cheese? Shows changes exist in (存在于) our life. Life changes and so we do. We must change ourselves to face the changing environment, or we will fail.
Just look at the cycle (循环) of the seasons. Trees bud (发芽) in spring and in summer their leaves turn green. In autumn, their leaves start to fall onto the ground. When winter arrives, there are no leaves on trees. Next spring the cycle begins again. Since we know there are cycles in nature, we can prepare for them. We know it is colder in winter and hotter in summer, so we can dress properly.
Since we accept the cycles of nature, we should also accept the changes in our life.
We can prepare ourselves for changes by becoming more flexible(灵活的). We can regard the changes in our life as chances. As we keep changing ourselves, we can keep up with the changes in our life.
小题1:What do writers use to share their life experiences?
| A．Stories | B．Newspapers | C．Basketballs | D．Pianos |
| A．changes exist in our life |
| B．we should move other’s things |
| C．we should use books to share our life experiences |
| D．there are difficulties in our life |
| A．we should wear warm clothes in winter |
| B．we should accept the changes in our life |
| C．we should prepare for the weather |
| D．leaves turn yellow in autumn |
| A．I have no chance to pass the test. |
| B．Exams are hard for me. |
| C．I have bad luck. |
| D．It’s good for me because I know there are more to learn. |
| A．Weather changes in different seasons. |
| B．Who Moved My Cheese? is a good book. |
| C．We should change ourselves when life changes. |
| D．We should not lose heart when meet with difficulties. |
BTW (by the way) BRB (be right back)
LOL (laughing out loud) IMO (in my opinion)
People also use many abbreviations(缩写). They are shortened forms of words. Some common abbreviations are:
Info(information) puter (computer)
Pie(picture) sec (second)
We usually don’t see people when we communicate on the Net, so people have new ways to show feelings. Most people use their keywords to draw “feeling”, such as:
:-)(happy) :-p(joking) :-( (sad) :-0 (surprised)
These days, many forums(论坛) have picture feelings. For example,
(sad) (happy)
There are even whole new words, like“newbie’s”(someone who is new on a chat board or forum).
It takes time for people to get used to e-talk. Also, different groups on the Net have their own special ways of communicating. Newbie’s have to ask other people what they mean. As the Internet grows, e-talk will continue to grow and change.
小题1:What does the underlined word “acronyms” mean?
| A．网友 | B．聊天室 | C．首字母缩写词 | D．关键词 |
| A．To show their feelings. |

| D．The person is joking that his computer is having problems. |

| B．be easy by people on the telephone |
| C．be used by people on the telephone |
| D．make life easier |
| A．E-talk Language | B．Picture Feelings |
| C．How to Use Abbreviations | D．use the Internet |
Some students think smoking is very cool, and they can see many people smoking around them. They want to have a 39 .
“If young people start smoking early, they will probably get addicted （上瘾的）to nicotine（尼古丁）. And it will be very hard to 40 later on,” said a professor. A study shows smoking is a problem for many Chinese teens. 41 can we do to make them stop smoking?
Some people think we can make a law. Teenagers under 18 are not allowed to smoke, 42 they should be fined. Parents should give up smoking. They can set an example （树立榜样）43 their children.
“Every year about four million people die of smoking. And if people 44 smoking, the number will increase （增加）10 million a year from now on,” said the World Health Organization. So we must learn and tell others about the 45 of smoking.

I have had thousands of classes since I started school nine years ago. But only one 36 was the most important.
It happened last term just after I had got a 37 result in an exam. I was sad and had lost my confidence. I decided to go to a class which can tell me how to be 38 .
The speaker walked into the room. But he did not start talking 39 a teacher. Instead, he held up a twenty yuan note(钞票) !
“Who wants this?” he asked. Unsurprisingly, 40 of us in the class held up our hands.
The speaker smiled. Then he put up the note on the blackboard and asked the same question. Again, we all put up our hands. The speaker smiled again, but 41 nothing. Suddenly, he threw the note onto the floor! Then he asked the same 42 a third time.
I didn’t 43 what the speaker was doing. Why was he asking the same question again and again? I didn"t know what to do. I wanted the note, 44 I put my hand up again. After a while, he 45 the note and started to laugh. “You have all just told me how to become successful,” 46 said to us with the note in his hand.
“The note is worth twenty yuan. It is 47 worth twenty yuan, even though I throw it on the floor. You are like the note. No matter 48 happens to you, you still have your worth.”
When I heard those words, I was deeply moved. Suddenly, I 49 I was worth a lot. I may have done badly in an exam, but it doesn"t 50 I can’ t do well in the future. If I believe in myself, I will be successful!
