Last week, I bought an alarm system for about $ 450. It consisted of a control unit with three small units. I put the control unit in the sitting-room and fastened the other units by the front door, back door and living-room windows. The instructions told us to choose three numbers, so we chose 491, the last three numbers of our telephone number.
Now I will explain how the alarm works:
1. There is a power siren in the control unit. It makes a very loud noise.
2. Each of the small units sends out beams or rays in different directions. If anything moves, it breaks a beam. This sends signal to the control unit. The siren makes a noise which you can hear 50 meters away.
3. When we go to bed, I press the three buttons numbered 4, 9 and 1. Then we have 30 seconds to get out of the room before the alarm starts to work. That night I slept soundly because I was sure that no burglar could get into our house. However, at about 2:10 a. m. , I woke up and heard the siren.
"There must be a burglar in the house?" Mary said, "What shall we do?"
"I'll go and see who's there," I said, "Stay here. Don't make a noise. "
I went down stairs quietly. When I reached the living-room, I switched on my torch and looked round the room. Then I turned the light on. I switched the siren off and searched the rooms downstairs. There was nothing wrong except that the back door was unlocked. I locked it, re-set the alarm and went back to bed.
About an hour later, the alarm started again. I jumped out of bed, fell over a chair in the dark and bumped into the bedroom door. Mary woke up and started hitting me with a torch. "Hey! Wait a minute!" I whispered, "It's only me. I'm going downstairs to see what's wrong."
I went down into the living-room and listened for a moment. The only sound I could hear was the siren. I tamed on the light and switched the siren off. As I did so, I glanced across at the curtains in front of the windows. I saw a house lizard (a kind of small animals)(壁虎) disappear behind the curtains.
"Oh!" I said to myself. "That's our burglar.”
When the lizard moved, it started the siren. I guessed the alarm had been made in Europe, where there are no house lizards.

Probably you have seen photos of the Grand Canyon（峡谷）, the great valley in the desert country of Arizona. But you must go there yourself to feel its true size and beauty. The Grand Canyon is one of the greatest natural wonders of the world
The Colorado River formed the Grand Canyon over millions of years. Slowly, the river cut down through hard rock. At the same time, the land was rising. Today the canyon is 1.5 kilometers and 445 kilometers long. The oldest rocks at the bottom of the canyon are more than 1 billion years old. The width varies from about 200 meters to 29 kilometers across. The rim or top of the canyon is about 2,300 meters above sea level on the South Rim, and about 3,000 meters on the other side. As a result, there are different kinds of plants and animals on opposite sides of the canyon. The South Rim is dry desert country. The North Rim has tall forests.
The canyon looks different at different times of day, and in different seasons and weather. At sunrise and sunset the red, gold, brown and orange colors of the rocks are especially clear and bright. In winter, the canyon is partly covered with snow.
The view from the South Rim of the Grand Canyon is the best. Most visitors come here and stay in campgrounds or hotels. Every point along the canyon’s edge offers a different view.
The North rim of the Canyon is quieter. It takes all day to drive there from the South Rim because there is only one bridge across the Colorado River. On the way, you go through Navado Indian lands, and a colorful pink desert called “The Painted Desert”.The best way to feel the true beauty of the Grand Canyon is to________.
| A．see its photographs | B．listen to the report about it |
| C．watch its introduction on TV | D．go there yourself and visit it |
The scene of the canyon is ________.
| A．various depending on different time and places |

| A．can go there in many direction | B．won’t spend much time on the way |
| C．can visit The Painted Desert on the way | D．needn’t go across any bridges |
If you want to have a visit to the Grand Canyon, you’d better go to _______.

Have you ever wondered why you sometimes take an almost immediate liking to a person you have just met? We often get the first impression of a people based on the color of a person’s skin or the manner in which he or she dressed. Meaning is conveyed not only by words or verbal languages but also by nonverbal communication systems, such as body behaviors.
Nonverbal communication is important because we use the actions of others to learn about their affective emotional states .Our emotions are reflected in our posture, face, and eyes—be it fear, joy, anger, or sadness—so we can express them without ever saying a word .For this reason, most of us rely heavily on what we learn through our eyes.
Nonverbal communication is significant in human interaction because it is usually responsible for the first impressions. More importantly, those first messages usually influence the perception(感知) of everything else that follows. Even how we select friends and sexual partners is grounded in first impressions with nonverbal communication.
Nonverbal communication is important because it is culture-related. It is based on different beliefs, religions, values and customs in different cultures. When, where, how, and to whom people display his or her specific nonverbal behaviors is greatly affected by culture and context. Culture determines what the appropriate nonverbal behavior is. For example, feelings of friendship exist everywhere but their expression varies. It may be appropriate in some countries for man to embrace each other and for women to hold hands; in other countries these displays of affection may be shocking. Each culture has its own specific interpretation on nonverbal communication. What is acceptable in one culture may be completely unacceptable in another. One culture may determine that snapping fingers to call a waiter is acceptable; another may consider this gesture rude. What is the best title of the passage ?
| A．Nonverbal communication and first impression | B．Nonverbal communication is culture-related |
| C．Nonverbal and verbal communication | D．The importance of nonverbal communication |

Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the world forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than just beautiful and interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks(老鹰), the farmers stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied(繁殖) quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws forbid the killing of any animals or plants on the danger list. Slowly, the number of some animals in danger is growing.Animals are important to us mainly because____.

Douglas Grace talks about his ideal city of the future.
I see the city of the future in three zones—inner, middle and outer. In the inner zone there will be no private cars. Public transport will be free and there will only be ambulances, fire engines, taxis and police cars. This inner zone will be the residential(住宅的) and recreational(娱乐的) area of the city. People will live there and go out to enjoy themselves—to cinemas and restaurants. There will be parks and open spaces, trees and lakes, schools and universities. This way, when people are at home, they can go out easily and safely.
Just outside the inner zone there will be big car parks for all private cars.
The banks and most of the shops and hospitals will be in the middle zone. These are things that people don’t need every day.
All the factories and offices will be in the outer zone. People will travel out of the center to work, and back to the center in the evenings. The inner zone will be cleaner and better to live in and there will be more space for industry on the outside.
