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 un-believably 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 holes 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 |

Pop music is the name for different forms of popular, commercial(商业) music. It had its beginning in the USA and spread throughout the whole world during the 1950s and 1960s. It is widely liked by the young people. The best known early form of pop music was “rock’ n’ roll”; another was “blues”. A more recent development is “folk-rock”. Pop music has taken the place of native music in many parts of the world; it has caused the number of people for jazz to become much smaller than it was in the 1950s and earlier, and it has now begun to rule musical stage productions. It’s a big industry. Much pop music is without artistic value, but the work of some pop singers, e.g. the Beatles, Bob Dylan, the groups like Floyd and Crosby, Stills and Nash, is on a higher musical level. And there is still a great interest in it today. Pop music concerts and festivals are held all over the world.All of the following forms belong to pop music EXCEPT __________________.

Never go into a supermarket hungry! This is a good piece of advice. If you go shopping for food before lunchtime, you’ll probably buy more than you plan to. Unfortunately, however, just this advice isn’t enough for consumers these days. Modern shoppers need an education in how and how not to buy things at the store. First, you check the weekly newspaper ads. Find out the items that are on sale and decide if you really need these things. In other words, don’t buy anything just because it’s cheaper than usual! “New and Improved!” or “All Natural” on the front of a package influence you. Instead, read the list of ingredients(contents) on the back. Third, compare prices: that is, you should examine the prices of both different brands and different sizes of the same brand.
Another suggestion for consumers is to buy ordinary items instead of famous brands. Ordinary items in supermarkets come in plain packages. These products are cheaper because producers don’t spend much money on packing or advertising. The quality, however, is usually as good as the quality of well-known name brands. In the same way, in buying clothes, you can often find high quality and low prices in brands th
at are not famous. Shopping in discount clothing stores can help you save a lot of money. Although these stores aren’t very attractive, and they usually do not have individual dressing rooms, not only are the prices low, but you can often find the same famous brands that you find in high-priced department stores.
Wise consumers read magazine ads and watch TV commercials, but they do this with one advantage: knowledge of the psychology behind the ads. In other words, well-informed consumers watch for information and check for misinformation. They ask themselves questions: Is the advertiser hiding something in small print at the bottom of the page? Is there any real information in the commercial, or is the advertiser simply showing an attractive image? With the answers to these questions, consumers can make a wise choice.All the following statements are true about the phrase “ordinary items” in Paragraph 2 EXCEPT __________.
| A．ordinary items never say “New and Improved” or “All Natural” |
| B．ordinary products are usually cheaper than famous brands |
| C．producers spend less money on packaging of ordinary items |
| D．the quality of ordinary items is usually as good as that of famous brands |
What does the writer think about ads? __________
| A．They are believable. | B．They are attractive. |
| C．They are full of misinformation. | D．They are helpful to consumers. |
One of the author’s suggestions to consumers is __________.
| A．to make use of ads |
| B．not to buy items with words like “New and Improved” or “All Natural” |
| C．to buy high quality items such as famous brands after lunch |
| D．to buy any ordinary items instead of famous brands |
The author implies that __________.
| A．going into the supermarket hungry, you may buy more than you plan to |
| B．the quality of ordinary items is usually high and the prices are relatively low |
| C．discount clothing stores are good places to go to |
| D．ads sometimes don’t tell the truth |
