Modern man has cleared the forests for farmland and for wood,and has also carelessly burned them. More than that,though,he has also interfered （干涉） with the invisible bonds between the living things in the forests. There are many examples of this kind of destruction. The harmfulness of man’s interference can be seen in what happened many years ago in the forest of the Kaibab plateau （凯亚巴布高原） of northern Arizona. Man tried to improve on the natural web of forest life and destroyed it instead.
The Kaibab had a storybook forest of largesized pine,Douglas fir,white fir,blue and Engelmann spruce. In 1882 a visitor noted,"We,who ... have wandered through its forests and parks,have come to regard it as the most enchanting region it has ever been our privilege （特权） to visit."This was also the living place of the Rocky Mountain mule deer. Indians hunted there every autumn to gather meat and skins. The forest also had mountain lions,timber wolves and bobcats that kept the deer from multiplying too rapidly.
Then,in 1906,President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was forbidden. Government hunters started killing off the deer’s enemies. In 25 years’ time,6,250 mountain lions,wolves and bobcats were killed. Before the program,there were about 4,000 deer in the Kaibab,by 1924,there were about 100,000.
The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer was permitted again. This caused a slight decrease in the deer herd （鹿群），but a far greater loss resulted from starvation （饥饿） and disease. Some 60 percent of the deer herd died in two winters. By 1930 the herd had dropped to 20,000 animals. By 1942 it was down to 8,000.The destruction of the environment of the Kaibab resulted from .
| A．turning the forest into cultivated land |
| B．interfering with natural cycle of forest life |
| C．forest fires caused by man’s carelessness |
| D．cutting the trees for building materials |
"Engelmann spruce"（Para. 2） is most likely the name of .
| A．a tree | B．an animal | C．a mountain | D．a game |
The number of the deer in the Kaibab had increased enormously in years’ time.
| A．25 | B．6 | C．18 | D．12 |
Years later,large numbers of deer in the Kaibab died mainly because of .
| A．the cold | B．the organized kill |
| C．the shortage of food | D．the poor management |
Long bus rides are like television shows. They have a beginning,a middle,and an endwith commercials （商业广告） thrown in every three or four minutes. The commercials are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard glides by outside the bus window. "Buy Super Clean Toothpaste.""Drink Good Wet Root Beer.""Fill up with Pacific Gas."Only if you sleep,which is equal to turning the television set off,are you spared the unending cry of "You Need It! Buy It Now!"
The beginning of the ride is comfortable and somewhat exciting,even if you’ve traveled that way before. Usually some things have changednew houses,new buildings,sometimes even a new road. The bus driver has a style of driving and it’s fun to try to figure it out the first hour or so. If the driver is particularly reckless （鲁莽的） or daring,the ride can be as thrilling （惊心动魄的） as a suspense story. Will the driver pass the truck in time? Will the driver move into the rightor the lefthand lane? After a while,of course,the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But you’ve got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops.
The end of the ride is somewhat like the beginning. You know it will soon be over and there’s a kind of expectation and excitement in that. The seat of course,has become harder as the hours have passed. By now you’ve sat with your legs crossed,with your hands in your lap,with your hands on the armrestseven with your hands crossed behind your head. The end comes just at no more ways to sit.According to the passage,what do the passengers usually see when they are on a long bus trip?

Disposing(处理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste-disposal problem becomes increasingly difficult.
During the eighteenth century, it was usual for several neighboring towns to get together to select a faraway spot as a dumpsite. Residents or trash haulers(垃圾托运者) would transport household rubbish, rotted wood, and old possessions to the site. Periodically(定期的) some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by.
Factories, mills, and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem.
Several facts make these choices unacceptable to modern society. The first problem is space. Dumps, which are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. Property is either too expensive or too close to residential(住宅区的)neighborhoods. Long-distance trash hauling has been a common practice, but once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is almost nonexistent.
Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste, however, continues to grow.
Recycling efforts have become commonplace, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a city's reusable waste.The most suitable title for this passage would be ______.
| A．Places for Disposing Waste | B．Waste Pollution Dangers |

The main purpose of writing this article is to ________.
| A．draw people's attention to waste management |
| B．warn people of the pollution dangers we are facing |
| C．call on people to take part in recycling programs |
| D．tell people a better way to get rid of the waste |
Sheep, like turkeys and ostriches, are not considered the cleverest animals. British scientists said last Wednesday human may have underestimated(低估) the woolly creatures. They could be much smarter than we think.
Researchers at the Babraham Institute in Cambridge, southern. England, have shown that animals have a good memory system and are extremely good at recognizing faces--which they think is a sure sign of intelligence.
Behavioral scientist Keith Kendrick and his friends trained 20 sheep to recognize and distinguish(区别) 25 pairs of sheep faces and used electrodes(电极) to measure their brain activity, which showed they could remember 50 faces for up to two years.
"If they can do that with faces, the fact is that they have to have reasonable intelligence, otherwise, what is the point of having a system for remembering anything else," Kendrick said in an interview.
So hours of seemingly mindless eating grass may not be so mindless after all.
Kendrick believes sheep got their reputation as dumb animals because they live in large groups and do not appear to have much ind
ividuality and are frightened of just about everything.
All animals, including humans, once they are frightened don't tend to show signs of intelligent action," he explained.
In research reported in the science journal Nature, Kendrick and his team showed that sheep, like humans, have a specialized system in the brain, which allows them to distinguish between many different faces that look extremely similar.
"The most important findings of the study is that they are able, both from a behavioral point of view and from looking at the way the brain is organized, to remember a large number of faces of individuals for a very long time," said Kendrick. "It is a very strange system. They are showing similar abilities in many ways to humans. " From the first paragraph we can find that ______.
| A．people used to think sheep are smarter than the other animals |
| B．people used to raise sheep in a wrong way |
| C．people don't consider sheep as clever animals |
| D．people have done a lot of research on sheep |
From what Kendrick said in the interview we learn that ________.
| A．scientists have learned a lot about sheep's intelligence |
| B．scientists have learned little about sheep's intelligence |
| C．scientists can't do anything more about sheep's memory |
| D．scientists don't have to research animals' memory |

| A．sheep are among the weak animals |
| B．it is not right for people to raise sheep in groups |
| C．when sheep eat grass in the fields their minds may be active |
| D．if people feel frightened, they may become more brave |

When I opened my e-mail the other day, a pretty woman named Rachel appeared on my computer screen. She greeted me by name and started talking with great enthusiasm. Every now and then she stopped to smile at me or blow a kiss. She was reading to me an e-mail from my brother, and a lot of it was about his getting the phone company to give him a high-speed Internet connection. It was pretty cool.
Rache
l was there thanks to a new technology called Facemail. Facemail lets you send e-mail that gets ready to the receiver by an attractive male or female form or by a clown(小丑). The software, which is free, can be downloaded at www. Facemail.com.
Facemail faces are lifelike, and they simulate(模拟) emotions based on emotions that you put in your text. For example, type in-X, and Rachel blows a kiss.
LifeFX, the company that develops the Facemail, is sure there are broad business uses. The reason e-business is not popular, the company says, is that buying over the Internet lacks the human touch. But what if you went to the Nike website and Michael Jordan greeted you by name, waited on you and personally closed the sale? And it is talking with Whirl(惠而浦公司) about using the technology in a computer screen on a fridge. Then if Morn can't be home when the kids get back from school, she can leave a note with voice and image telling them what there is to eat.
Facemail could get hot fast. Personally, I'm a fan. But Facemail should be used with care. The clown looks lively and funny at first. But if you select the clown, put a few rude words in an e-mail and add some angry emotions, you've got a Psycho-mail(疯人型电子邮件).The pretty woman that appears on the writer's computer screen was ______.
A. a woman working on the Internet B. his brother's girlfriend
C not a real person D. the picture of his pen-friend The main advantage of Facemail is that ______.

| B．you can see the person who sends you the e-mail |
| C．yon can send an e-mail free of charge |
| D．e-mail can be attractive in a more lovely way |

| A．Famous people like Michael Jordan also like to use Facemail |
| B．Facemail can make shopping on the Internet more interesting |
| C．Nike website will increase its sales by Jordan |
| D．Michael Jordan will serve you himself on Nike website |
What is the writer's attitude towards Facemail?
| A．He thinks it needs further improvement. |
| B．He thinks it cool and funny. |
| C．He thinks it a danger to the Internet. |
| D．He thinks people should be careful with Facemail. |
