More than 10 years ago, it was difficult to buy a tasty pineapple. The fruits that made it to the UK were green on the outside and, more often than not, hard with an unpleasant taste within. Then in 1996, the Del Monte Gold pineapple produced in Hawaii first hit our shelves.

       The new type of pineapple looked more yellowy-gold than green. It was slightly softer on the outside and had a lot of juice inside. But the most important thing about this new type of pineapple was that it was twice as sweet as the hit-and-miss pineapples we had known. In no time, the Del Monte Gold took the market by storm, rapidly becoming the world’s best-selling pineapple variety, and delivering natural levels of sweetness in the mouth, up until then only found in tinned pineapple.

       In nutrition(营养) it was all good news too. This nice-tasting pineapple contained four times more vitamin C(维生素C) than the old green variety. Nutritionists said that it was not only full of vitamins, but also good against some diseases. People were understandably eager to be able to buy this wonderful fruit. The new type of pineapple was selling fast, and the Del Monte Gold pineapple rapidly became a fixture in the shopping basket of the healthy eater.

       Seeing the growing market for its winning pineapple, Del Monte tried to keep the market to itself. But other fruit companies developed similar pineapples. Del Monte turned to law for help, but failed. Those companies argued successfully that Del Monte’s attempts to keep the golden pineapple for itself were just a way to knock them out of the market.

We learn from the text that the new type of pineapple is ______.

   A. green outside and sweet inside         B. good-looking outside and soft inside

   C. yellowy-gold outside and hard inside    D. a little soft outside and sweet inside

Why was the new type of pineapple selling well?

   A. It was rich in nutrition and tasted nice.    B. It was less sweet and good for health.

   C. It was developed by Del Monte.         D. It was used as medicine.

The underlined word “fixture” in Paragraph 3 probably refers to something ______.

   A. that people enjoy eating             B. that is always present

   CV. that is difficult to get                     D. that people use as a gift

We learn from the last paragraph that Del Monte ______.

   A. allowed other companies to develop pineapples

 B. succeeded in keeping the pineapple for itself

   C. tried hard to control the pineapple market

   D. planned to help the other companies

A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces (熔炉) that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.

The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.

After the explosion gravity pulls in what’s left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.

The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!

That’s what we know about black holes. What we don’t know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.

But if the black hole doesn’t keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly—somewhere else. But where? A different place, perhaps, or a different time — many years in the past or future.

Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed. So far the time being, black hole must remain a mystery.

Black holes are a mystery—but that hasn’t stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth’s energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste—a sort of huge waste disposal(处理) in the sky!

When the star begins to die ______.

A. there is no fuel left in it                                B. its outer layer goes into space first

C. a huge explosion will happen                         D. it doesn’t give off light any longer

Which of the following doesn’t help produce a black hole?

A. The gravity inside the star is very strong.        B. The light can’t go out of the star.

C. The star becomes smaller and smaller             D. The dying star shines very brightly.

The black hole ______.

A. continues becoming smaller and smaller all the time

B. goes into another universe and becomes a white hole

C. can pull in everything we know of in the world

D. will appear at another place at a different time

What’s the best title for this passage?

A. A New Scientific Discovery: Black Holes

B. How Do Black Holes Come Into Being?

C. What Are Black Holes?

D. Travel Through A Black Hole

A new enemy is threatening Japanese traditions: leisure（闲暇）. As part of its attempt to increase imports, the government is trying to get people to work less and spend more. The workers are disgusted.

The figures support the western prejudice（偏见） that the Japanese are all work and no play. Trying to force workers away from their desks and machines, the government said last April that the country should cut down from its 2,100 hours average work year to 1,899 hours and a five-day week by 1992. Beginning in February, banks and stock markets will be closed on Saturdays, staff of civil service will be forced out of their offices two Saturdays a month. The government hopes that others will follow that practice.

But some persuasion will be needed. Small companies are very angry about it and they fear competitors may not cut hours. The unions are no happier: they have even advertised in newspapers arguing their case against the foreign pressure that is forcing leisure upon them. They say that shorter hours are a disguised（隐性的） pay cut. The industrialists, who have no objection to the government’s plans, admit that shorter hours will help them cut costs. Younger Japanese who are supposed to be acting against their hard-working parents, show no sign of wanting time off, either. But unlike older workers, they do spend money in their spare time. Not content with watching television, they dance, dress up, sit in cafes, go to pop concerts and generally drive the leisure-industry boom. Now that they know how to consume, maybe the West can teach them to relax and enjoy themselves, too.

The purpose of getting the Japanese to have more spare time is that           .

    A．the government wants to show more concern for the health of the people

    B．the government needs to get more goods from abroad

    C．the Japanese have been working too hard

    D．the Japanese hope to change the western prejudice

The group of people who welcome the shorter-hour system in Japan is           .

    A．the small companies          B．the industrialists

    C．the unions                   D．the younger generation

The unions think that           .

    A．the shorter hours they work, the higher pay the can get

    B．the more they work, the less leisure they can enjoy

    C．the shorter hours they work, the less pay they can have

    D．the greater pressure the government is forcing on them, the less happy they can be

The best title for this passage can be           .

    A．Oh no! Not Saturday Again!   B．Leisure: the Greatest Threat!

    C．Enjoy While You are Young!   D．Less Work and More Play!
