It was evening when my parents and I ventured across Nemeiben Lake, in Northern Saskatchewan. This vast lake had a unique reputation as being the best fishing and tourist resort.

With the boat undocked and the gear and luggage stored beneath the security of the seats, we set off into the setting sun at 8:30.

Unlike my parents , I had never been on a fishing boat before and was captivated(迷住) by the speed and grace in which it traveled through the waves. The lake was deserted as the sky began to darken and looked more threatening by the minute.

Suddenly the boat hit something with such a force that we all fell over in our seats. The whole boat shook for a moment, before water started to trickle slowly over stern. My father went to the back and after many attempts to start the engine, he began to look very worried. The water was now rushing in at a much faster rate, tipping the boat at an awkward angle.

We tried our best to hold on to something. The worst was yet to come. With our life jackets secured and fastened, we waited as the boat sank deeper into the water. We were soon immersed in the chilly depths. The biting cold was more terrifying than anyone could imagine.

My parents, who were dressed in floater jackets, clung desperately to each other, trying to keep their heads above water. I, on the other hand, wasn’t so fortunate. A strong gust of wind blew briskly across the lake, bringing with it, torrential rain and threatening thunderstorms. The strong waves carried me on into the night. The waves continued to pound violently, forcing me underwater.

The following morning a fisherman found us. By that time, our body temperatures were twenty-four degrees, which meant we were nearly dead. Later investigation showed that we had been in the water for fifteen hours.

60. What is the main idea of the passage?

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

Pronouncing words of a language is a skill. Every normal person is expert in the skill of pronouncing their own language; but few people are ever skilled at pronouncing foreign languages. Now there are many reasons for this, some obvious, some perhaps not so obvious. But I suggest that the reason why people in general do not speak foreign languages much better than they do their own language is that they fail to grasp the true nature of the problem of learning to pronounce, and never set about solving it in the right way. Far too many people fail to realize that pronouncing a foreign language is a skill-one that needs careful training of a special kind, and one that cannot be gained by just leaving it to take care of itself. I think even teachers of language, while recognizing the importance of a good accent, tend to neglect(忽略), in their practical teaching, the branch of study which has something to do with speaking the language. So the first point I want to make is that English pronunciation must be taught. The teacher should be prepared to devote some of the lesson time to this, and by his whole attitude(态度)to the subject should get the student to feel that here is a matter worthy of receiving close attention, thus when other aspects(方面)of English, such as grammar or spelling, are allowed for the moment, to take second place, there is something else.

Except for the question of time given to pronunciation, there are two other requirements for the teacher: the first, knowledge; the second, technique.

1. Why don't people speak a foreign language better than they speak they native language?

A. Because they can't grasp the nature of the problem of learning to pronounce.

B. Because they think pronouncing a foreign language is a impossible.

C. Because they never solve the problem in any way.

D. Because they pay more attention to pronunciation than anything else.

2. What is the passage mainly about?

A. Grammar should be paid no attention to.

B. Pronunciation is the most important aspect in learning a foreign language.

C. Spelling should not be taught in class.

D. Knowledge and technique are unnecessary in learning a foreign language.
