ted the Solo Trek.

The Solo Trek had a 120 horsepower engine with twin fans. Only one person flies. As you fly above the roofs, you lean a little forward. You can see everything under you. You are flying like Superman.

Inventors have tried to make it easy for people to fly. Paul Moiler has been working on his flying car for 30 years. He now says it is ready for tests. It would take off and land vertically, go 600 miles an hour, and deliver 20 miles to the gallon. A computer would do the actual flying. He says it could be sold next year for about a million dollars.

NASA is working with Moshier to help develop his flying machine. The first users are likely to be military.

It's been 50-years since Robert Fulton invented his airphibian, a flying car. It flew, and is now in the Smithsonian Museum.

Getting dreams to fly is never easy.

The Solo Flyer is able to lift off the ground by using ______.

Trees are useful to man in three important ways: they provide him with wood and other prod

ucts; they give him shade; and they help to prevent droughts and floods.

Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important. (78)In his eagerness to make money from trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he bad. And besides, be is usually too careless to plant and look after new trees. So the forests slowly disappear.

This does not only mean that man will have fewer trees. The results are even more serious: for where there are trees, their roots break up soil—allowing the rain to sink in—and also bind the soil, thus preventing it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing remains but worthless desert.

Two thousand years ago a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It set up the empire but, without its trees, its soil became poor and it grew weak. When the empire fell to pieces, the home country found itself faced with floods and starvation.

What is the most important service of trees to man according to the passage？

A．They help him make money.

B．They give. him wood and other products.

C．They help him prevent droughts and floods.

D．They give him shade.

Manners in school, as everywhere else, are important to happy relation within the group. W

How often one hears children wishing they were grown up, and old people wishing they were

young again. Each age has its pleasures and its pains, and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets.

Childhood is a time when there are few responsibilities to make life difficult. If a child has good parents, he is fed, looked after and loved, whatever he may do. It is impossible that he will ever again in his life be given so much without having to do anything in return. In addition, life is always presenting new things to the child—things that have lost their interest for older people because they are too well-known. But a child has his pains: he is not so free to do what he wishes to do; he is continually being told not to do things, or being punished for what he has done wrong.

When the young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way that he used to as a child, he will go hungry. And if he breaks the laws of society as he used to break the laws of his parents, he may go to prison. If however, he works hard, keeps out of trouble and has good health, he can have the great happiness of building up for himself his own position in society.

According to Paragraph 2, the writer thinks that______.

A．life for a child is comparatively easy

B．a child is always loved whatever he does

C．if much is given to a child, he must do something in return

D．only children are interested in life

Everyone uses the expressions AM and PM. But do you exactly know what they mean and how th

ey came into being？

As you know, the turning of the earth makes the sun and the stars seem to move across the sky. Daylight, of course,【21】, when the sun rises in the east and when the sun is high【22】the sky, between these two positions, half of the daylight hours have been spent.

Therefore, by noticing【23】the sun stood in the sky, early man know they could tell the time of the day, At night the motion of the stars【24】the same purpose. The important thing in keeping time is to know the exact moment of【25】. For each of us, wherever we are, noon is when the sun is directly overhead. Think of an imaginary line【26】the sky, stretching from the north point of your horizon just to the south point.

When the sun cross your meridian (子午线), it is noon for you. When the sun still【27】of this line, or the meridian, it is morning. After the sun has crossed this line, it is【28】.

The Latin word for "midday" is "deridian",【29】which comes our word meridian. So AM is an abbreviation (缩写词) for "ante meridean", or before midday, and PM for after midday. Each or the world's time zones (时区) is about fifteen degrees wide in longitude (经度), which is about the distance the sun moves through tile sky in all hour.【30】lives in the same time zone observes noon at the same moment. In this way, the time is different by one hour as you move through each time zone.

第8题

Human needs seem endless. They might be regarded as making up several levels. When there i

s enough money to satisfy one level of needs, another level appears. The first and most basic level of needs involves food. Once this level is satisfied, the second level of needs, clothing and some sort of shelter, appears. By the end of World War II , these needs were satisfied for a great majority of Americans. Then a third level appeared. It included such items as automobiles and new houses. By 1957 or 1958 this third level of needs was fairly well satisfied. Then, in the late 1950s, a fourth level of needs appeared: the "life-enriching" level. While the other levels involve physical satisfaction, that is, the feeding, comfort, safety , and transportation, this level stresses mental needs for recognition, achievement, and happiness. It includes a variety of goods and services. Among them are vacation trips, the best medical and dental care, and recreation. Also included here are fancy goods and the latest styles in clothing. On the fourth level, a lot of money is spent on services, while on the first three levels more is spent on goods. A fifth level would probably involve needs that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime, and prejudice. After filling our stomachs, our clothes closets, our garages, our teeth, and our minds, we now may seek to ensure the health, safety, and leisure to enjoy more fully the good things on the first four levels.

According to the passage, man will begin to think about such needs as housing and clothing only when______.

A．he has saved up enough money

B．he has grown dissatisfied with his simple shelter

C．he has satisfied his hunger

D．he has learned to build houses

第9题

There was a time when, if a lady got onto a crowded bus or train, a gentleman would immedi

ately stand up and offer her his seat. Today a gentleman will probably look out of the window or hide behind his newspaper. Either way, the lady will have to stand until someone gets off.

You can' t entirely blame men for this change in manners. The days are gone when women could be treated as the weaker sex. A whole generation of women has grown up demanding equality with men; not just equality in jobs or education, but in social attitudes. Hold a door open for some women and you're likely to get an angry lecture on treating women as inferiors, unable to open doors for themselves. Take a girl out for a meal and she'll probably insist on paying her share of the bill.

It' s no wonder, then, that men have given up some of the gestures of politeness and consideration which they used to show towards women. On the other hand, man' s politeness is perhaps slowly being replaced by true consideration for the needs and feelings of women, so that men can see women as equal human beings.

What do gentlemen now do when a lady gets on a crowded bus or train？

A．They will stand up reluctantly.

B．They will offer her their seats after a while.

C．They will pretend not to see her.

D．They will get off the bus.
