After Man has dreamed about flying for a long time. Michael Moshier is a dreamer. He inven

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.

Michael Moshier looked at the jet belt and the rocket belt that was developed 20, 30 years ago. Nothing ever came from them. People still can't fly.

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 ______.

A．a solar powered engine

B．engine-powered twin fans

C．large flapping wings

D．rotating blades

It is often difficult for a man to be quite sure how much tax he ought to pay to the gov

ernment because it depends on so many different things：whether the man is married;how many children he has;whether he supports any relations，how much interest he receives，how much he has spent on his house during the year，and so on. All this makes it difficult to decide exactly how much the tax is.There was an artist who was always very careful to pay the proper amount.

One year，after posting his check as usual，he began to wonder if he had paid enough，and after a lot of work，with a pencil and paper，he found that he had not. He thought that he owed the government something.

He was just writing another check to send it to the tax collector when the postman dropped a letter into the box at the front door. Opening it，the artist was surprised to find inside it a check for five pounds from the tax collector. The official explained that too much had been paid，and that therefore the difference was now returned to the taxpayer.

11. According to the passage，to decide the exact amount of tax to be paid is ____________.

A. simple

B. easy

C. difficult

D. interesting

12. It is mentioned in the passage that one has to pay tax according to ____________.

C. how old one’s children are

D. where one lives

13. The word “proper” in the second paragraph means __________.

A. small

C. right

D. wrong

14. After a lot of work，the artist thought that he had paid the government ____________.

A. less tax than he should have

B. more tax than he should have

C. as much tax as usual

D. just enough tax

15. Why did the tax collector send a letter to the artist？

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

第5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.

One of the good things for men in women's liberation is that men no longer have to pay wom

en the old-fashioned courtesies.

In an article on the new manners, Ms. Holmes says that a perfectly able woman no longer has to act helplessly in public as if she were a model. For example, she doesn't need help getting in and out of cars. She also says there is no reason why a man should walk on the outside of a woman on the sidewalk.

As far as manners are concerned, I suppose I have always been a supporter of women's liberation. Over the years, out of a sense of respect, I imagine, I have refused to trouble women with outdated courtesies.

It is usually easier to follow rules of social behaviour than to depend on one's own taste. But rules may be safely broken, of course, by those of us with the gift of natural grace. For example, when a man and woman are led to their table in a restaurant and the waiter pulls out a chair, the woman is expected to sit in the chair. That is according to Ms. Ann Clark. I have always done it the other way, according to my wife.

It came up only the other night. I followed the hostess to the table, and when she pulled the chair out I sat on it, quite naturally, since it happened to be the chair I wanted to sit in.

"Well, "my wife said, when the hostess had gone, "you did it again."

"Did what？" I asked, utterly confused.

"Took the chair."

Actually, since I'd walked. through the restaurant ahead of my wife, it would have been awkward, I should think, not to have taken the chair. I had got there first, after all.

Also, it has always been my custom to get in a car first, and let the woman get in by herself. This is a courtesy I insist on as the stronger sex, out of love and respect. In times like these, there might be attackers hidden about. It would be unsuitable to put a woman in a car then shut the door on her, leaving her at the mercy of some bad fellow who might be hiding in the back seat.

It can be concluded from the passage that______.

A．men should walk on the inside of a sidewalk

B．women are becoming more capable than before

C．in women's liberation men are also liberated

D．it's safe to break rules of social behaviour

第10题

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.
