Millions of stars are traveling about in space. A few form. groups which journey together,

but most of them travel alone. And they travel through a universe so large that one star seldom comes near to another.

We believe, however, that some two thousand million years ago, another star wandering through space, happened to come near our sun. Just as the sun and the moon raise tides on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; a large tidal wave' must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance (动荡) came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and threw off small parts of itself into space. These small pieces have been going round the sun ever since. They are the planets (行星).

Millions of stars are______.

A．following a regular path in space

B．always travelling together

C．seldom wandering about in the universe

D．moving about without a fixed course

第6题

The first hotels were very different from today's hotels. They were small inns built along

the road. Later, as people began to travel by train, hotels were built in the centers of large cities. Usually located near railroad stations, these hotels were many stories tall and had hundreds of rooms.

Although trains were a popular means of travel for some time, automobiles slowly began to take their place. Automobile travel caused problems for city hotels, which did not have enough parking space for so many cars.

People who traveled by automobile needed a different kind of hotel. They needed places to stay that were near highways and had room to park. Motorists did not like to drive in heavy city traffic to reach a hotel. The answer to the motorists' problems came when a new kind of hotel was built. These new buildings were called motels, a word made from the first part of MOTORIST and the last part of HOTELS.

Motels were much smaller than hotels. Built on ground level, often in separate units, they were more convenient for people traveling. The separate units also made them quieter than hotels, best of all, there was more than enough room for cars to park. ,

Now, many big hotels in the cities are being torn down. They can no longer make enough money to stay in business. In their place, many small motels have been built on the outskirts(近郊) of cities. Motels have become a big business in the United States.

The first hotels were built______.

A．with hundreds of rooms

B．around the city centers

C．near railway stations

D．quite close to roads.

第7题

Among the question of design, construction, and operation remaining to be solved before co

mmercial airliners travel faster than sound is the difficult problem of sonic boom (声震) , the explosive sound generated when an object moves through the air at supersonic speed(超音速).

A sound is a pressure disturbance: a sonic boom, like other explosive sounds, is the result of an abrupt change in pressure. An airplane in subsonic flight produces weak changed in pressure, but because these disturbances travel at the speed of sound, they move faster than the airplane and stay in front of it. In effect, these disturbances warn the air to get out of the way, and the an does just jet, however, gets ahead of its own pressure disturbances. Consequently a wave of suddenly com pressed air--a shock wave--builds up and is thrown off like the wave ;hat spreads from the bow of a speedboat.

Can sonic booms be eliminated？ The answer is a categorical negative--they are an innerent(内在的) part of supersonic flight--but the sonic boom probably can be reduced; government and private research is now under way to improve understanding of the sonic boom. If and when the booms can be reduced to tolerable levels, commercial supersonic transports can come rata service.

Before commercial airliners travel faster than sound, problems must 0e solved regarding ______.

A．design

B．Construction

C．operation

D．all of the above

第8题

Years ago our cities were full of cars, buses and trucks. Now the streets are completely c

ongested (拥挤的) and it is very difficult to drive a car along them. Drivers must stop at hundreds of traffic lights. What are our cities going to be like in ten or twenty years？ Will enormous (巨大的) motorways be built across them？ With big motorways cutting across them, full of noisy, dirty cars and lorries, our cities are going to be awful places. How can we solve the problem？

There are some good ideas to reduce the use of private cars. In 1989, for example, the authorities in Rome began an interesting experiment: passengers on the city buses did not have to pay for their tickets.

In Stockholm there was another experiment: people paid very little for a season ticket to travel on any bus, trolley bus, train or tram in all the city.

In many cities now some streets are closed to vehicles, and pedestrians are safe there.

In London there is another experiment: part of the street is for buses only, so the buses can travel fast. There are no cars or taxies in front of them.

What the writer worries about in a big city is ______.

A．the number of traffic lights

B．the shortage of buses

C．the lack of motorways

D．the traffic congestion

第10题

Under normal conditions, the act of communication requires the presence of at least two

persons: one who sends and one who receives the communication. In order to communicate thoughts and feelings, there must be a conventional system of signs or symbols that mean the same to the sender and the receiver.

The means of communication are too numerous and varied for systematic classification; therefore, the analysis must begin with the means of receiving communication. Reception of communication is achieved by our senses. Sight, hearing, and touching seem to play the most important roles. Smell and taste play very limited roles, for they cannot receive intellectual expression from fully developed systems of sings and symbols.

Examples of visual communication are gesture and imitation. Although both frequently accompany speech, there are systems that rely solely on sight, such as those used by deaf, and dumb persons. Another means of communicating visually is by signals of fire, smoke, flags, or flashing light. Feelings may be simply communicated by touch, such as by handshaking or backslapping, although a highly developed system of hand-stroking has enabled blind, deaf, and dumb persons to communicate intelligently. Whistling to someone, applauding in a theater, and other forms of communication by sound rely upon the ear as a receiver. The most fully developed form. of auditory communication is, of course, the spoken language.

The means of communication mentioned so far have two features in common: they last only a short time, and the persons involved must be relatively close to each other. Therefore, all are restricted in time and space.

1、Reception of communication______ .

A、is more important than sending messages

B、 depends on two persons

C、 involves use of the senses

D、 play only limited roles

2、Applauding is specifically mentioned as an example of ______.

A、communication by sound

B、 gesture and imitation

C、 communication by sending a message

D、 communication between the listener and speaker

3、Persons who cannot see, hear, or speak are able to communicate through ______.

A、gesturing
