What is color？ Why do some objects look red, others green, others blue？
Color is caused by reflected light rays. We see color because objects reflect light. Some thing that is red reflects mostly red light. In the same way, a green object reflects mostly green light. White objects reflect all colors of light. Black objects do not reflect any light.
What happens to the colors of light that are not reflected？ They are absorbed by the object. The darker the color, the less light is reflected and the more light is absorbed. Light that is absorbed is turned into heat. For this reason, dark-colored clothes are warmer in the sunlight than light-colored clothes.
Which is the main idea of this passage？
A．Dark-colored clothes are warmer in the sunlight.
B．Objects absorb part of the sunlight.
C．Color is caused by reflected light rays.
D．A red object reflects mostly red light.
Sitting in a dark theater, watching the images on the screen, they enter another world that is real to them. They become involved in the lives of the characters in the movie, and for two hours, they forget all about their own problems. They are in a dream world where things often appear to be more romantic (浪漫的) and beautiful than in real life.
The biggest "dream factories" are in Hollywood, the capital of the film industry. Each year, Hollywood studios make hundreds of movies that are shown all over the world. American movies are popular because they tell stories and they are well-made. They provide the public with heroes who do things the average person would like to do but often can't. People have to cope with many problems and much trouble in real life, so they feel encouraged when they see the" good guys "win in the movies.
The Americans go to the movies mainly because they want______.
A．to enjoy a good story
B．to experience an exciting life

Droplets and ice crystals behave somewhat like dust in the air made visible in a shaft(束) of sunlight. To the casual observer, dust seems to act in a totally random fashion, moving about wildly without fixed direction. But in fact dust particles are much larger than water droplets and they finally fall. The cloud droplet of average size is only 1/2,500 inch in diameter. (78)It is so small that it would take sixteen hours to fall half a mile in perfectly still air, and it does not fall out of moving air at all. Only when the droplet grows to a diameter of 1/125 inch or larger can it fall form. the cloud. The average raindrop contains a million times as much water as a tiny cloud droplet. The growth of a cloud droplet to a size large enough to fall out is the cause of rain.
What is the main topic of the passage？
A．The mechanics of rain.
B．The climate of North America.
C．How gravity affects air current.
D．Types of clouds.
【B1】
This time, the Greater London Council is looking into the possibility of building a Channel link straight to London. (79) A bridge would cost far more than a tunnel, but you would be able to go by rail or by car on a bridge, whereas a tunnel would provide a rail link only.
Why is this idea being discussed again？ Is Britain becoming more conscious of the need for links with Europe as a result of joining the EEC(欧共体) ？ Well, perhaps. The main reason, though, is that a tunnel or bridge would reach the twenty square kilometers of London' s disused dockland(船坞地). A link from London to the continent would stimulate trade and re-vitalize(使…各新有活力) the port, and would make London a main trading center in Europe. (80)With a link over the Channel, you could buy your fish and chips in England, and be able to eat them in France while they were still warm!
Which of the following statements is TRUE？
A．Swimming across the Channel takes less than four hours.
B．The idea of a Channel tunnel or bridge is a very new one.
C．It is considered to be more difficult to swim across the channel than any other means.
D．A tunnel or bridge would only reach as far as the coast.
Your Bean Steak (素肉排), Sir!
What sort of food are we likely to be eating in the year 2000？
Most people, when you ask them a question like that, either say: " There won't be any left, " or "Whatever it is, there won't be much taste in it." Of course, there are good reasons for being worried about the world's food supplies in the future.Nevertheless, not all the experts share these worries.
For one thing, although the world's population is rising fast, food production is keeping pace with it, even in developing countries.It is therefore argued that the main reason why people are hungry is not that there is a world food shortage but that methods of cultivation are not sufficiently advanced in some areas and the food is not fairly distributed (分配 ).
This does not mean, however, that our diet (饮食 ) will go on being the same.In many industrialized countries, people feed animals with grain to produce high-quality beef, even though the grain would feed the human population, and use fishmeal to fatten pigs to improve the quality of bacon.While not many of us would like fishmeal for lunch, its nutritional value is high and the unattractive fish it is made from can be presented to the public in colorful packets of fish fingers.
By the year 2000, many of these problems will have been solved.Scientists are already capable of making steaks from soy beans.It is quite obvious that there will still be enough to eat, if we are not too particular about where the food comes from and what it is made of.

A、poor farming methods and bad distribution

3.The word "bacon" in Line 5, Para.3 most probably is().
A、a kind of "meat" made from grain
