A new generation addiction is quickly spreading all over the world. Weboholism（网瘾）, a twentieth century disease, affects people from different ages. They surf the net, use e-mail and speak in chat rooms. They spend many hours on the computer, and it becomes a compulsive habit. They cannot stop, and it affects their lives.

Ten years ago, no one thought that using computers could become compulsive behavior that could affect the social and physical life of computer users. Such behavior has seriously affected teenagers and college students. They are likely to log(写日志) on computers and spend long hours at different websites.

They become hooked（着迷） on computers and gradually their social and school life is affected by this situation. They spend all free time surfing and don’t concentrate on homework, so this addiction influences their grades and success at school. Because they can find everything on the websites, they hang out there. Moreover, this addiction to websites influences their social life.

They spend more time in front of computers than with their friends. The relation with their friends changes. The virtual life becomes more important than their real life. They have a new language that they speak in the chat rooms and it causes cultural changes in society.

Because of the change in their behavior, they begin to isolate themselves from society and live with their virtual friends. They share their emotions and feelings with friends who they have never met in their life. Although they feel confident on the computer, they are not confident with real live friends they have known all their life. It is a problem for the future. This addictive behavior is beginning to affect all the world.

This was Larry’s another underwater expeditions(探险). However, this time, it was quite different. He decided to take his daughter along with him. She was only ten years old. This would be her first trip with her father on what he had always been famous for.

Larry first began diving when he was his daughter’s age. Similarly, his father had taken him along on one of his expeditions. Since then, he had never looked back. Larry started out by renting diving suits from the small diving shop just along the shore. He had hated them. They were either too big or too small. Then, there was the instructor. He gave him a short lesson before allowing him into the water with his father. He had made an exception. Larry would never have been able to go down without at least five hours of theory and another similar number of hours on practical lessons with a guide. Children his age were not even allowed to dive.

After the first expedition, Larry’s later diving adventures only got better and better. There was never a dull moment. In his black and blue suit and with an oxygen tank fastened on his back, Larry dived from boats into the middle of the ocean. Dangerous areas did not prevent him from continuing his search. Sometimes, he was limited to a cage underwater but that did not bother him. At least, he was still able to take photographs of the underwater creatures.

Larry’s first expedition without his father was in the Cayman Islands. There were numerous diving spots in the area and Larry was determined to visit all of them. Fortunately for him, a man offered to take him around the different spots for free. Larry didn’t even know what the time was, how many spots he dived into or how many photographs he had taken. The diving spots afforded such a wide array of fish and sea creatures that Larry saw more than thirty varieties of creatures.

Larry looked at his daughter. She looked as excited as he had been when he was her age. He hoped she would be able to continue the family tradition. Already, she looked like she was much braver than Lorry had been then. This was the key to a successful underwater expedition.

1.In what way was this expedition different for Larry?

A. His daughter had grown up.

B. He had become a famous diver.

C. His daughter would dive with him.

D. His father would dive with him.

2.What can be inferred from Paragraph2?

A. Larry was lucky to have got such a chance to dive.

B. Larry liked the rented diving suits.

C. Ten-year-old children were permitted to dive.

D. Divers had to buy diving equipment.

3.Why did Larry have to stay in a cage underwater sometimes?

A. To take photos more conveniently.

B. To dive into the deep water.

C. To admire the underwater view.

D. To protect himself from danger.

4. What can be learned from the underlined sentence?

A. Larry didn’t wear a watch.

B. Larry enjoyed the adventure.

C. Larry had a poor memory.

D. Larry was not good at math.

5.What did Larry expect his daughter to do?

A. Make a good diving guide.

B. Have longer hours of training.

C. Take a lot of photo underwater.

D. Become a successful diver.

THANK-you cards--heartfelt expressions of gratitude for gifts, services and general kindness--seem to be rare in an age when the Internet continues to reduce human interaction.

Although our society has changed greatly over the past century, the etiquette of thank-you notes has not.

While most people would agree that thank-you notes under these circumstances are a necessity, there are still those who forever postpone or are forgetful for unknown reasons.

And at no time of the year are thank-you notes more visible (or lacking) than June, the month of graduations, and the beginning of summer parties.

"It's a must-do thing. A real thank you does not come by e-mail. It comes in the mail in an envelope. And what comes out of an envelope is a beautiful thing to touch and to handle and to pass around for everyone to read," said etiquette expert Letitia Baldrige.

Don't think for a second that Baldrige is old-fashioned. Handwritten thank-you notes--any handwritten correspondence, for that matter- have taken on an air of extra importance and dignity (庄重) in this e-hyper (电子狂躁的) world.

Baldrige remains hopeful that the art may be enjoying a renaissance (复兴,再生).

More than simply obeying rules of etiquette, thank-you cards are a sign of caring.

"They're more important now than ever," expert Peter Post says. "You are building a relationship. And part of building that relationship is that you acknowledge when someone has done something nice for you. "

"The payoff," Post says, "can be huge. The more we do it, the more it comes back to us, and it's a benefit to us all. It makes our world a little bit nicer place to live in. "

1.Nowadays thank-you cards seem to be rare mainly because ______.

A. people think that they are out of fashion

B. it is quicker to say thanks by e-mail

C. the Internet has reduced people's contact

D. people are too busy to remember these things

2.From the context, the word "etiquette" in the second paragraph probably means ______.

A. old objects for sale

B. rules for people to obey

C. hand-made articles

D. customs for polite behavior

3.The author implies in this article that ______.

A. old-fashioned people take a negative attitude to e-mails

B. the changing society is making people impolite and lazy

C. modern technology is driving people apart

D. the e-hyper world is not a nice place to live in

4.What’s Baldrige’s attitude towards handwritten thank-you cards?

A. Regretful to disappear

B. Promising to come back

C. Old-fashioned to keep

D. Unnecessary between friends

Changing the world does not only mean finding a medicine for cancer or finding the origin of human beings, but recycling a piece of paper as well. 1. . What follows are three simple ways we can go green and change the world.

Recycle

Every day about 63 million newspapers go out, and 44 million of them are thrown away. By recycling the newspaper alone we could save half a million trees a week. New phones, iPods, or computers are created every day. 2. . By taking them to the local stores that collect them, they can go to people who don’t have enough money to buy one.

Go vegetarian one day a week

According to the scientists at New York University, if the whole population skips one meal of chicken, the amount of carbon dioxide(二氧化碳) would be the same amount if more than half a million cars were taken off roads in the US. 3. .

Refuse bottled water

Most people drink bottled water because they think that bottled water is healthier than tap water. However, 25% of the bottled water actually comes from tap water. Not only are you drinking the same water as the water in your house but you are paying more. 4. . So it is necessary to use reusable water bottles instead of plastic water bottles.

Changing the world had to start from small things. 5.. However, every little helps a mickle(多量). Keep in mind what Margaret Mead once said, “Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it’s the only thing that ever has.”

A. So give up just one day of eating meat.

B. One of the most serious threats to our planet is plastic pollution.

C. Going green is a way that we can have a meaningful influence on the world.

D. Also plastic bottles will cause plastic pollution.

E. It may seem as if the small changes are not influencing the world.

F. But what happens to the old ones?

G. Actually there is little or no difference between bottled water and tap water.

Death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two phases --- clinical or temporary death and biological death．Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage．The organism can still be revived(复活)．Biological death occurs when changes in the organism lead to the “breaking up” of vital cells and tissues．Death is then unchangeable and final．
Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs．The best method developed so far involves cooling of the organism, combined with narcotic sleep．By slowing down the body’s metabolism(新陈代谢), cooling delays the processes leading to biological death．
To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta． The scientist put Keta to sleep with a narcotic． Then they surrounded her body with ice-bags and began checking her body temperature．When it had dropped to 28 degrees the scientists began draining blood from an artery．The monkey’s blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in．For twenty minutes Keta remained in this state．Her temperature dropped to 22 degrees．At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing．After two minutes Keta’s heart became active once more．After fifteen minutes, spontaneous(自发的)breathing began, and after four hours Keta opened her eyes and lifted her head． After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe and ran with it around the room．Her behavior differed little from that of a healthy animal．
1.For a person who suffers from the clinical death, _________．
A． his most important organs are damaged．
B． he still has the possibility of getting back to life．
C． he can not avoid final death．
D． he is still very much alive
2.Scientists try to make the time of clinical death longer in order to __________．
A． slow down the body’s metabolism．
B． bring vital cells and tissues back to active life．
C． cool the organism．
D． delay the coming of biological death．
3. How did the scientists put Keta into clinical death?
A． By putting her to sleep, lowering her temperature and draining her blooD．
B． By surrounding her body with ice-bags and draining her blood．
C． By lowing her blood pressure and stopping her heart from beating．
D． By draining her blood, lowering her blood pressure and stopping her breathing．
4. All of the following indicate that the monkey has almost restored to her original physical state except the fact that__________．
A． her heart beat again．
B． she regained her normal breath．
C． she rejected a penicillin injection．
D． she acted as lively as a healthy monkey．

--- I am really struck by your spoken English．You speak so fluently．Have you been abroad?
