If you want to be a babysitter, you can call (021)29564938.BHave you ever heard of satellites(卫星)? What are they used for?Satellites are helping to forecast(预报) the weather now. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere, where the weather forms. They send these pictures to the weather stations. So meteorologists(气象学家) can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change so that it can work better for people.Nowadays, more and more countries have weather satellites. Nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive the new pictures, the meteorologists compare them with the earlier ones. Perhaps they may find the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. In their neeteorologists can say the weather will change soon. So the weather satellites are a great help to the meteorologists. Before satellites were invented, the meteorologists could only forecast the weather for about 24 or 48 hours. Now they can make good forecasts for about two weeks. Soon they may be able to forecast the weather for more than two weeks or more ahead.With the development of the society, weather satellites will work better and better in people's life.54. From the second paragraph we can know satellites travel ____.A. in the atmosphereB. in spaceC. on the groundD. in the clouds55. According to the passage, maybe meteorologists will soon be ableto forecast the weather for ____.A. about 24 or 48 hoursB. about a weekC. less than two weeksD. more than 14 days or even longer56. What's the main idea of this passage?A. Satellites can reach any part of the world.B. Satellites can take pictures of the earth.C. Satellites are used for forecasting the weather.D. More and more countries have weather satellites.CDifferent weather makes people feel different. It influences(影响) health, intelligence (智力) and feelings.In August, it is very hot and wet in the southern part of the United States. People there have heart trouble and other kinds ofhealth problems during this month. In the Northeast and the Middle West, it is very hot at some times and very cold at other times. People in these states have more heart trouble after the weather changes in February or March.The weather can also influence intelligence. For example, in a 1983 report by scientists, the IQ(智商) of a group of students was very high when a very strong wind came, but after the strong wind, their IQ was 10% lower. The wind can help people have higher intelligence. Very hot weather, on the other hand(另一方面), can make it lower. Students in many schools of the United States often get worse on eonths of the year (July and August).Weather also has a strong influence on people's feelings. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel unhappy during the cold weather. But fat people may have a hard time in hot summer. At about 18℃, people become stronger.Low air pressure(气压) may make people forgetful. People leave more bags on buses and in shops on low air pressure days. People feel best at a temperature of about 18℃.Are you feeling sad, tired, forgetful or unhappy today? It may be the weather's problem.57. What can cause problems on health?A. Hot and wet weather.B. Wind.C. Warm weather.D. Clear water.58. A report shows that people may have higher intelligence when ____ comes.A. the rainB. a strong windC. the very hot weatherD. the low air pressure59. What does the writer want to tell us in the third paragraph?A. Hot or cold weather influences all people in the same way.B. Weather influences people's feelings.C. The IQ changes when weather changes.D. People feel good on lowpressure days.60. Which is the best title for this passage?A. Hot Weather Causes Health ProblemsB. Different Weather Makes People Feel BadC. Weather Influences FeelingsD. Weather Influences Health, Intelligence and FeelingsDPeople often think of the North Pole(北极) and the South Pole as similar frozen (冰冻的) wastelands. They are both places with very cold temperatures and few people live there. However, the Northand South Poles are not much alike as people may imagine.The North Pole has no land, only thick ice. Temperatures seldom go above 32℉, at which water turns into ice. Most of the time, it stays below zero. In winter, temperatures are usually as low as －30℉.Although conditions were very poor, people tried for many centuries to reach the North Pole. About 100 years ago, two men, Robert Peary and Matthew Henson, were able to get to this environment full of troubles and difficulties. They reached the North Pole on April 6th, 1909. It was really a hard trip for them.There are few things more dangerous than crossing the Arctic(北极圈) on foot. People who stayed there may face many problems: very cold temperatures, sudden storms, and even hunger. Most of the area is uninhabited. Few people can live in such a difficult place.People might think that with such low temperatures for most of the year, the ice would be thick and hard. However, this is not true in the Arctic. The movement of the ocean water under the ice may often cause many different changes on the surface. Sometimes the ice breaks into two opening lanes of water(水道) called “leads”. Anyone who falls into a lead can be frozen to death in a few minutes.61. Which of the following is this passage probably from?A. A book review.B. A science book.C. A school report.D. A computer magazine.62. According to the passage, what happened about 100 years ago?A. Two men succeeded in getting to the North Pole.B. Temperatures in the North Pole went above 32℉.C. The environment in the North Pole suddenly became worse.D. The North Pole changed into thick ice because of the temperatures.63. What does the underlined word “uninhabited” probably mean?A. Having bad weather.B. Comfortable.C. Difficult.D. With no people living there.64. What's the reason for the ice to break into two opening lanes of water?A. The temperature suddenly drops.B. The water under the ice is frozen.C. The ocean water under the ice moves.D. The surface is covered with lots of ice.65. What does this passage mainly talk about?A. The thick ice in the North Pole.B. A difficult trip to the North Pole.C. The real situation in the North Pole.D. The differences between the North Pole and the South Pole. Ⅸ. 任务型阅读(共5小题；每小题2分, 满分10分)Jimmy has never taken part in a camping trip before. He finally started his first camping trip this spring. The following is what he told us about the camp：I always wondered what it would be like to go camping. I love sports but this is one thing I haven't done before. So when one of my classmates advised us to go camping this spring, I jumped with happiness.The night before camping, I checked(检查) my bag: a sleeping bag, a water bottle, a flashlight(手电筒), some clothes and some food. I was ready!We got to the camp by bus early the next morning. There were twenty of us and we were divided(分开) into four groups. We played games to get to know one another better. After lunch, we learnt how to keep safe in the forest. We also played games that taught us to work with and trust others. In the evening, we walked for an hour in the forest. And at the end of the night, we had a big campfire. We sat around it, sang songs and told scary stories. This was certainly not my last camping trip!66、67题完成句子； 68题简略回答问题；69题找出并写下全文的主题句；70题将文中画线句子译成汉语。

Mr. Black went to town on business. On his way home, he found a big pile of hay in front of him. He got down from his horse. The hay had fallen off a wagon. A boy was standing by the wagon and looked worried. He was sorry for the little driver. "Now don't worry, my boy," Mr. Black said, "Come with me to the village over there, and I'll find someone to help you get the hay back onto the wagon."In the village Mr. Black's friend asked him and the boy to have dinner. He enjoyed the man's dinner, but the boy still looked worried. "Dad won't like this," the boy said in a low voice. "Don't worry too much," said Mr. Black, "Just be careful next time. Now have your dinner, and you needn't hurry.""But I have been away for a long time. Dad will be angry.""Oh, come now," said Mr. Black, "Your dad will understand. He will be glad if he knows that you had a good dinner. I'll go with you and explain what has happened. By the way, where's your dad now?" The boy answered, "He's under the pile of hay!"39.

There is a popular joke about it on the Internet. "The longest distance in the world is not between life and death, but between you and me when I hold your hand in the street but cannot see your face."Air pollution is one of the causes of lung(肺) cancer. What shall we do to keep healthy in this situation? Try to remember the following advice.● Reduce outdoor activities.● If you have to go outside, remember to wear a mask.● Drink enough water every day and have fresh food.● Wash hands and face aft er outdoor activities.● Keep indoor environment clean.44.

Air pollution can make people blind.B. We'd better wash hands and face before going outside.C. We should stay indoor as much as possible.CThe word "day" has two meanings. When we talk about the number of days in a year, we are using "day" to mean 24 hours. But when we talk about day and night, we are using "day" to mean the time between sunrise and sunset. Since the earth looks like a ball, the sun can shine on only half of it at a time. Always one half of the earth is having day and the other half night. A place is moved from day into night and from night into day over and over by the spinning(旋转) of the earth. At the equator(赤道) day and night are sometimes the same length. They are each twelve hours long. The sunrises at 6 in the morning and sets at 6 in the evening. For six months the North Pole is tilted(倾斜) toward the sun. In those months the Northern Hemisphere(半球) gets more hours of sunlight than the Southern Hemisphere. Days are longer than nights. South of the equator nights are longer than days. For the other six months the North Pole is tilted away from the sun. Then the Southern Hemisphere gets more sunlight. Days are longer than night. North of the equator nights are longer than days. Winter is the season of long nights. Summer is the season of long days.49. When the Western Hemisphere is having day, the Eastern Hemisphere is having .A. both day and nightB. dayC. neither day nor nightD. night50. A place is moved from day into night and from night into day over and over by of the earth.A. the pushingB. the pullingC. the spinningD. the passing51. At the equator day is as long as night .A. sometimesB. neverC. usuallyD. always52. When the North Pole is tilted toward the sun, the Northern Hemisphere gets sunlight.A. lessB. moreC. allD. no53. When it is winter in China, .A. the USA is tilted toward the sunB. the South Pole is tilted away from the sunC. the North Pole is tilted toward the sunD. the North Pole is tilted away from the sunDGood morning. The program today is about music. The word "music" comes from the Greek word "muse". The Muses are the goddesses of the arts. Music is only one of the arts. It is like the spoken language, but it uses sounds. Today's program brings together music from different comers of the world. Who invented music? Who sang the first song? No one knows exactly the answers to these questions. But we know that music plays an important part in almost everyone's life. Babies and young children love to hear people singing to them. When they are a little older, they like to sing the songs they have heard. When children go to school, their world of music grows. In the middle grades students take music lessons. When they reach high school, they become interested in listening to pop music.The records we have chosen for you today are from American country music, Indian music, pop music and so on. Music has meaning for everyone. It can make people happy or it can make them sad. In this program we shall study the language of music. We shall be trying to find out more about how music works. We shall try to find out how music says what people feel.Now, here comes the music today, I shall explain why they are all good music...54.
