1.A wind tunnel is used for testing planes or plane models.In a wind tunnel air is blown over a plane ora model placed in a test section.Wind tunnel test sections are different in size depending onairflow speed requirements.Some low-speed tunnels have test sections large enough for acomplete small plane.In the very high speed tunnels used for space testing，however，the model may be as small as a pencil.There are two ways of feeding air to the test section.In the constant flow tunnel，airflow produced by electric fans is forced through the tunnel to the test section，then through another tunnel section back to the starting point for reuse.The other way involves storing high-pressure air in a box，sending it out by a controlling device to pass through the tunnel and test section into another box.This way is usually used for a very short period of high-speed airflow.Wind tunnels are usually used to test planes before they are flown.Problems in a plane carl be found when it meets the high-speed airflow in the tunnel.For example，if the wings are built so that they would weaken at high speeds，this fact can be discovered in the tunnel，thus saving many lives and millions of dollars.In a wind tunnel，scientists also find out how different planes will act at different speeds.They find out such things as how the air dives by the wing surfaces，how slowly a plane can fly before it starts to drop，and howfastit can climb.As mentioned in the last paragraph，a wind tunnel can be used to find out____.

6.根据以下资料，回答42-45题。 　　England is not a big country: from north to south and from east to west it is only about three hundred miles across．But for a small country it has a surprising range of climate．People who have never visited England or who have visited only one part of it often makes the mistake of thinking that it is a cold and wet country．Except for the summer months of June to September, this is probably true of the north of England and the Midlands．In the south, however, the climate is much more pleasant．One result is that when people retire from the job in the north, they often prefer to move down to the south. 　　Perhaps the warmest part of the country is the southwest, which consists of (is made up of) the counties of Devon and Cornwall, where palm trees, bamboo and many semitropical plants grow well．Flowers and vegetables ripen as much as a month earlier than those elsewhere．Farmers in the areas gain a higher price for their vegetables and flowers because they are ready earlier．In winter there may be several feet of snow in other parts of England but there will probably be no snow at all in the southwest．This may be one of the reasons why the southwest is one of England's most popular holiday areas.42 The distance from the center of England to south coast is about

One of the cows broke into thedoor of the storehouse with her horns and all the animals began to help themselves to the grains.It was just then that Mr. Jones woke up. The next moment he and his four men were in thestorehouse with whips in their hands, whipping in all directions. This was more than the hungryanimals would bear. Together, though nothing of the kind had been planned beforehand, theyjumped upon their masters. Mr. Jones and his men suddenly found themselves being struck with the horns and kicked from all sides. The situation was quite out Of their control. They had never seen these animals act like this before.

Passage Four

I hear many parents complaining that their teenage children are rebelling. I wish it were so. At young age you ought to be growing away from you parents. You should be learning to stand on your own two feet.

But take a good look at the present rebellion. It seems that teenagers are a1l taking the same way of snowing that they disagree with their parents. Instead of striking out on their own，most of them are clutching at one another’s hands for reassurance.

They say they want to dress as they please，but all of them wear the same clothes. They set off in new directions in music ，but all of them end up huddled round listening to the same record.Their reason for thinking or acting in this and that way is that the crowd is doing it. (84)It has become harder and harder for a teenager to stand up against the popularity wave and go his or her own way. These days every teenager can 1earn from the advertisements what a teenager should have and be. And many of today ’s parents have come to award high marks for the popularity of their children. (85)All this adds up to a great barrier for the teenager who wants to find his or her own path. But the barrier is worth climbing over. The path is worth following. You may want to listen to classical music instead of going to a party. You may want to collect rocks when everyone else is collecting records. You may have some thoughts that you don ’t care to share at once with your classmates. Well ，go to it. Find yourself. Be yourself. Popularity will come-will the people who respect you for who you are. That’s the only kind of popularity that really counts.Which of the following is NOT true according to the passage？

Most parents,I suppose,have had the experience of reading a bedtime story1their children.And they must have realized how difficult it is to write a2children'sbook.Either the author has aimed(定目标）too3,so that children can't follow whatis in his(or more often,her)story,4the story seems to be talking to the readers.

The best children's books are 5very difficult nor very simple,and satisfy(令人满意的）the6 who hears the story and the adult(成年人）who 7it.Unfortunately（不幸的是），there are in fact few books like this,8 the problem of finding the rightbedtime story is not 9to solve.This may be why many of the books regarded as10of children's literature(文学）were in fact written for11 “Alice in Wonderland"is perhaps the most obvious(明显）of thisChildren,left for themselves,often12the worstpossible interest in literature just leave a child in a bookshop or a13and he will morewillingly choose the books written in an unimaginative(开非想象的）way.orhavelook at the most children’s comics(连环图书），full of the stories and jokes which ate the rejectionsof teachers and righting-thinking parents.Perhaps we parents should stop14 to brainwash(洗脑）children into accepting（接受）our taste in literature.After all,children and adults are so15 that we parentsshould not expect that they will enjoy the same books.So I suppose we'll just have to compromise(妥协）over the bedtime story.6（单选）

17.Most students choose “Homestay” accommodation when they study abroad：others select Homestay even if they are not on a study visit.Statistics show that it’s a form of accommodation gaining in popularity all the time.But what is Homestay? And what makes it so popular?Homestay means living with a family，or“host family”as we say.There are three ways of doing it：choose to learn English in a language school near to your Homestay location：have your English classes in the house with a member of the family who is a qualified teacher;select not to have classes at all when you visit——a popular choice if you want to do the tourist thing for example.Even in their busy summer period the organizations that arrange the Homestays will always try to place you with the most suitable host family to match your requirements.Placement( 安置)organizations think about location，interests，language level，eating requirements，allergies(过敏)and other requests you may have.Though prices vary according to your needs，good quality Homestay accommodation can berelatively economical--and although you may be charged an extra amount of money if you want your Homestay in or near the city center.Even if you stay further out，you can expect your journey into the center not to exceed 30 minutes.Not only does Homestay accommodation represent value for money， it also gives you an excellent opportunity to practice English with your host family.This is a very important extra for students who like to speak as much English as possible. But if you plan to learn English，why not have your English classes in your host family. There’s no better way to learn English than this—the perfect combination of learning and accommodation combined with the cultural experience !Who will consider students’requirements before their Homestay starts?

Passage Two

In the modern technological world the sea offers many resources to help mankind survive. (82)Resources on land are beginning to grow less. The sea, however, still offers hope to supply many of man’s needs.

The riches of the sea yet to be developed by man’s technology are impressive. Oil and gas explorations have existed for nearly thirty years. Valuable amounts of minerals such as iron, nickel and copper and so on exist on the ocean floor, ready to be mined.

Fish farming promises to be a good way to produce large quantities of food.The culture of fish and shellfish is an ancient skill practiced in the past mainly by Oriental peoples.

Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm temperature of the ocean can be used in a way similar to the steam in a steamship. Ocean currents and waves offer possible use as a source of energy such as hydroelectric power.

Technology is enabling man to explore ever deeper under the sea.The new undersea technology is providing divers with diving suits and undersea chambers that are kept at sea level pressure. The development of strong,new materials has made this possible. The technology to harvest the sea continues to improve. By the year 2000, experts believe that the problems to exploit the food, minerals, and energy sources of the sea will be largely solved.It can be inferred from the passage that_______.

20.__________the government agrees to give extra money, the theatre will have to be closed next month.
