Washington — The largest ozone (臭氧)hole ever observed has opened up over Antarctica, according to the scientists of the US National Aeronautics and Space Administration (NASA). They believe it is a sign that ozone — destroying gases produced years ago are just now causing the largest quantities of ozone to disappear.
This year’s South Pole ozone hole spreads over about 28.5 million square kilometers, an area three times larger than the landmass of the United States.
Pictures of the hole have been offered by NASA. The hole appears as a giant blue mass, totally covering Antarctica and stretching to the southern tip of South America.
“The last time the ozone hole was close to this size was in 1998, when it spread over about 27.2 million square kilometers,” NASA said.
Paul Newman, who works with NASA’s Total Ozone Mapping Spectrometer (TOMS) instrument on a NASA satellite, said ozone watchers had expected a big hole this year, but not this big.
The Antarctica ozone hole, first observed in 1985, is caused by the depletion (损耗) of Earth protecting ozone by human-made chemicals such as chlorofluorocarbons, known as CFCs.
“Even though these chemicals were not allowed to use from the beginning of 1987, they remain in the atmosphere and will continue to do so for years,” Newman said.
“This year’s large hole may have been caused by a change in a swirling high-level air current over Antarctica, which circles the area and contains the zone hole,” Newman said.

To be a good teacher, you need some of the gifts of a good actor; you must be able to hold the attention and interest of your audience; you must be a clear speaker, with a good, strong, pleasing voice which is fully under your control; and you must be able to act what you are teaching, in order to make its meaning clear.
Watch a good teacher, and you will see that he does not sit still before his class:he stands the whole time he is teaching; he walks about, using his arms, hands and fingers to help him in his explanations, and his face to express feelings. Listen to him, and you will hear the loudness, the quality and the musical note of his voice always changing according to what he is talking about.
The fact that a good teacher has some of the gifts of a good actor doesn’t mean that he will indeed be able to act well on the stage, for there are very important differences between the teacher’s work and the actor’s. The actor has to speak words which he has learnt by heart; he has to repeat exactly the same words each time he plays a certain part, even his movements and the ways in which he uses his voice are usually fixed beforehand. What he has to do is to make all these carefully learnt words and actions seem natural on the stage.
A good teacher works in quite a different way. His audience takes an active part in his play：they ask and answer questions, they obey orders, and if they don’t understand something, they say so. The teacher therefore has to meet the needs of his audience, which is his class. He cannot learn his part by heart, but must invent it as he goes along.

When I met him, I had a lot of anger inside of me. I’ve lived my whole life in Spanish Harlem, but in my neighborhood, there are shoot-ups all the time. I know kids who have been shot or beaten up. I have friends who ended up in prison. I could have ended up that way, too, but Mr. Clark wouldn’t let that happen.
Mr. Clark worked long hours, making sure I did my work. My grades rose. In fact, the scores of our whole class rose. One day, he took our class to see The Phantom of the Oper
a, and it was the first time some kids had ever been out of Harlem. Before the show, he treated us to dinner at a restaurant and taught us not to talk with our mouths full. We did not want to let him down.
Mr. Clark was selected as Disney’s 2000 Teacher of the Year. He said he would draw three names out of a hat; those students would go with him to Los Angeles to get the award. But when the time came to draw names, Mr. Clark said, “You’re all going.”
On graduation day, there were a lot of tears. We didn’t want his class to end. In 2001, he moved to Atlanta, but he always kept in touch. He started giving lectures about education, and wrote a bestselling book based on his classroom rules, The Essential 55. In 2003,
Mr. Clark took some of us on a trip to South Africa to deliver school supplies and visit the orphanages (孤儿院). It was the most amazing experience of my life. It’s now my dream to one day start a group of women’s clubs, helping people from all backgrounds.Without Mr. Clark, the writer .

As if there weren’t enough of them in the world already, scientists have succeeded in cloning flies. The alike fruit flies are the first insects ever cloned, says the Canadian team that created them. The question everyone asks is why anyone would want to clone flies in the first place. She hopes that the insects , which are very easy to experiment with , will help to adjust the cloning process in other animals and even in humans, where the technique is being researched to aid production of therapeutic (治疗的) stem cells.
In cloning, the DNA-containing nucleus of an adult cell is injected into an egg whose own nucleus(细胞核) has been removed. At the moment, the majority of cloned mice, sheep and other animals die before birth. It is thought this is because the adult DNA is not properly ‘reprogrammed’.
Using flies, researchers might discover genes that are important for this reprogramming, and that have matches in other animals. That is because it is relatively easy in flies to knock out the function of a single gene and then attempt cloning with these cells, which will test whether that gene is important. If such genes are confirmed, then in theory cloned mammalian embryos(晶胚) might be grown in selected solutions that change the activity of those genes to improve the technique’s success rate. Although some groups have attempted to clone insects before, Lloyd says this is the first time it has been successful. The team used a slight difference on the standard cloning process: they transferred nuclei taken from embryos rather than fully-grown adult cells. They sucked several nuclei (pl)out of developing fly embryos, and injected them into a fertilized(已受精的) fly egg. From over 800 early attempts, they cloned five adult insects, the group reports in the journal Genetics.The best title of this passage probably is _______.
| A．The importance of clone |
| B．First insects are cloned |

The failure of most cloned animals is due to _______.
| A．the difference of other animals’ genes |
| B．the improper technique of clone |
| C．the complex of other animals |
| D．the improper rearrange of the adult gene |
It can be inferred from the last paragraph that ______.

| B．the clone of insects were never experimented before |
| C．this time scientists cloned flies successfully and easily |

Last August, Joe and Mary Mahoney began looking at colleges for their 17-year-old daughter, Maureen. With a checklist of criteria (衡量标准)in hand, the Dallas family looked around the country visiting half a dozen schools. They sought a university that offered the teenager’s intended major, one located near a large city, and a campus where their daughter would be safe.
“The safety issue is a big one,” says Joe Mahoney, who quickly discovered he wasn’t alone in his worries. On campus tours other parents voiced similar concerns, and the same question was always asked: what about crime? But when college officials always gave the same answer -----“That’s not a problem here,”-----Mahoney began to feel uneasy.
“No crime whatever?” comments Mahoney today. “I just don’t buy it.” Nor should he: in 1999 the U.S. Department of education had reports of nearly 400,000 serious crimes on or around our campuses. “Parents need to understand that times have changed since they went to college,” says David Nichols, author of Creating a Safe Campus. “Campus crime mirrors the rest of the nation.”
But getting accurate information isn’t easy. Colleges must report crime statistics(统计数字) by law, but some hold back for fear of bad publicity（关注）, leaving the honest ones looking dangerous. “The truth may not always be serious,” warns S. Daniel Carter of Security on Campus, Inc., the nation’s leading campus safety watchdog group.
To help concerned parents, Carter promised to visit campuses and talk to experts around the country to find out major crime issues and effective solutions.It is often difficult to get correct information on campus crime because some colleges ____.
| A．receive too many visitors | B．mirror the rest of the nation |
| C．hide the truth of campus crime | D．have too many watchdog groups |
The underlined word “buy” in the third paragraph means _____.
| A．mind | B．admit | C．believe | D．expect |
We learn from the text that “the honest ones” in the fourth paragraph most probably refers to colleges _____.
| A．that are protected by campus security | B．that report campus crimes by law |
| C．that are free from campus crime | D．that enjoy very good publicity |
What is the text mainly about?
| A．Exact campus crime statistics. | B．Crimes on or around campuses. |
| C．Effective solutions to campus crime. | D．Concerns about kids’ campus safety. |
