The Internet has opened up a whole new online world for us to meet, chat and go where we’ve never been before.
But just as in face to face communication, there are some rules of behavior that should be followed when on line. 71 Imagine how you’d feel if you were in the other person’s shoes.
For anything you’re about to send: ask yourself, “Would I say this to the person’s face?” if the answer is no, rewrite and reread. 72
If someone in the chat room is rude to you, your instinct (本能) is to fire back in the same manner. But try not to do so. 73 If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.
74 Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it’s a stupid question or an unnecessarily long answer, be kind about it. If it’s a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn’t give you license to correct everyone else. 75 At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended.
It is not polite to ask others personal questions such as their age, sex and marital status. Unless you know the person very well, and you are both comfortable with sharing personal information, don’t ask such questions.
A．Repeat the process till you feel sure that you’d feel comfortable saying the words to the person’s face. B．Everyone was new to the network once. C．The basic rule is simple: treat others in the same way you would want to be treated. D．When you send short messages to a person online, you must say something beautiful to hear.

Water and its importance to human life were the centre of the world’s attention last week. March 22 was World Water Day and 36 the theme “Water for Life”.
There are more than one billion people in the world who live without 37 drinking water. The United Nations 38 to cut this number in half by 2015.
Solving such a big problem seems like a(n) 39 challenge. But everyone, 40 teenagers, can do something to help. A teenage girl in the US has set an example to the 41 of her age around the world.
Rene Haggerty, 13, was awarded the 2004 Gloria Barron Prize for her work— 42 discarded(废弃的) batteries（电池）which pollute water.
In 2003, Haggerty went on a field trip to the Great Lakes Science Centre in Ohio. There she saw an exhibit about how 43 in old batteries harm the water of Lake Erie.
Haggerty learnt that 44 the batteries was an easy solution. “I think everybody can do it, because everyone 45 batteries, and it can make a big difference.” With these words, she began to 46 awareness in her area.
She 47 her county government and school board. She got permission to start a recycling programme in schools 48 the public library, hospital, and churches. With help from her family, friends and local waste-management 49 , she gathered containers, arranged transportation, and made a(n) 50 video.
Over the past two years, she collected four tons of batteries and drew the attention of officials, who were in charge of a battery recycling programme but had made 51 progress.
When asked 52 she feels like a hero, Haggerty is quite ____53 . “Not really. Well, maybe for the fish I saved!”
Every year the Gloria Barron Prize 54 young Americans aged 8 to 18 who have shown leadership and courage in 55 the public and the planet. Each year ten winners receive US $ 2,000 each, to help with their education costs or their public service work.

Every human being, 36 what he is doing, gives off body heat. The usual problem is 37 dispose of it. But the designers of the Johnstown campus of the University of Pittsburgh set themselves the 38 problem — how to collect body heat. They have designed a collection system which utilizes 39 body heat, but the heat given off by such objects 40 light bulbs and refrigerators as well. The system works so well 41 no conventional fuel is needed 42 the campus’ six buildings comfortable.
Some parts of most modern buildings — theatres and offices 43 classrooms — are more than amply heated by people and lights and sometimes must be air-conditioned 44 in winter. The technique of 45 heat and redistributing it is 46 “heat recover”. A few modern buildings recover 47 , but the university’s system is the first to recover heat 48 some buildings and re-use it in 49 . Along the way, Pitt has learned a great deal about some of its heat producers. The 50 a student studies, the more heat his body 51 . Male students emit more heat than 52 students, and the larger a student, the more heat he 53 . It is tempting to 54 that the hottest prospect for the Johnstown campus would be a 55 , over-weight male genius.

Which came first, the chicken or the egg? This is one of life’s __1__ questions and people have been debating about it for thousands of years. Now scientists believe they have solved this _2__. Researchers from Sheffield and Warwick Universities in England discovered the answer __3__. They used a super computer to observe the shell-making process while a new shell was __4__. Then they found one protein called OC17 that is __5__ for forming eggshell. This is only found inside a chicken’s body, which is proof that the _6__ came first. The team was __7__ looking at how animals and birds make eggshells but suddenly made their surprising __8__. The big question now is where chickens came from. The _9__ is from dinosaurs.
The research team said eggshells are one of nature’s most __10__ creations. Professor John Harding from the team told reporters: “Understanding how chickens make eggshells is fascinating in itself, but it can also be __11__ in designing new materials.” Eggshells are very lightweight but incredibly strong. Even the most up-to-date materials __12__ by the world’s top engineers can not produce anything as __13__ as an eggshell. Professor Harding added that __14__ eggshells could help to cure bone diseases and design materials for the construction industry.“Nature has found wonderful ways that __15__ for all kinds of problems in materials science and technology — we can learn a lot from them.” he said.

Thanks to a combination of young businessmen, large numbers of university students and revitalization (新生) efforts by the local and national governments, today’s Nanjing has an 36 of youthful exuberance (繁茂) that would have been 37 only a few decades ago. 38 , the city, a booming city of 6.5 million on the banks of the Yangtze River some 185 miles west of Shanghai, bears 39 resemblance to the former capital of China that suffered the worst cruelty and violence of World War II.
40 Nanjing has shown a remarkable capacity for reinvention during its 2,500-year history. And in recent years, the city has moved 41 its tragic past to become a vital engine of China’s economic growth, thanks 42 to its position in the middle of China’s prosperous eastern seaboard. Growth has also 43 thanks to improved ground transportation: A new bullet train linking Nanjing and Shanghai started service last year, 44 travel time between the cities from several hours to just 75 minutes, and a Beijing-Shanghai high-speed line is 45 to open later this year, with a stop in Nanjing. Within the city, two metro lines were built in the last few years; 15 more are planned to begin service by 2030.
Signs of Nanjing’s 46 wealth and optimism can be seen everywhere. In the heart of the downtown Xinjiekou district, a bronze statue of Sun Yat-sen, 47 the father of modern China, looks 48 over a busy 49 area.
There is perhaps no more 50 symbol of the city’s transformation than the Zifeng Tower, a 1,480-foot skyscraper that opened its doors last May. 51 offices, restaurants and an InterContinental hotel, the tower is the second-tallest building in China and billed as the seventh-tallest in the world.
Underlying all this development is a large Chinese and 52 student population — there are several major universities, plus a branch of Johns Hopkins’s international studies school. In fact, art and music 53 in all sorts of places.
On a larger 54 , local government officials and private investors are pushing the city as a rising center for contemporary art and architecture, hoping to attract 55 from the neon-bathed streets of its neighbor Shanghai.

Most people believe they don’t have much imagination. They are 11 . Everyone has imagination, but most of us, once we become adults, forget how to 12 it. Creativity isn’t always 13 with great works of art or ideas. People at work and in their free time 14 think of creative ways to solve problems. Maybe you have a goal to achieve, a tricky question to answer or you just want to expand your mind! Here are three techniques to help you.
Making connections. This technique involves taking 15 ideas and trying to find links between them. First, think about the problem you have to solve or the job you need to do. Then find an image, word, idea or object, for example, a candle. Write down all the ideas/words 16 with candles: light, fire, matches, wax, night, silence, etc. Think of as many as you can. The next stage is to relate the 17 to the job you have to do. So imagine you want to buy a friend an original 18 ; you could buy him tickets to match or take him out for the night.
NO limits! Imagine that normal limitations don’t 19 . You have as much time /space / money, etc. as you want. Think about your goal and the new 20 . If your goal is to learn to ski, 21 , you can now practise skiing every day of your life (because you have the time and the money). Now 22 this to reality. Maybe you can practise skiing every day in December, or every Monday in January.
Be someone else! Look at the situation from a 23 point of view. Good businessmen use this technique in trade, and so do writers. Fiction writers often imagine they are the 24 in their books. They ask questions: What does this character want? Why can’t she get it? What changes must she make to get what she wants? If your goal involves other people, put yourself in their 25 . The best fishermen think like fish!

As I understand, if scientists produced a human clone, there would be a great risk of it having a disease. Nobody seems to understand the ageing process of a clone. It would be terrible if a baby was the age of its parent at 31 . Its cells would grow old fast and it would die young. 32 until the technique is perfectly safe, it should be 33 .
I'd love to have a clone of 34 . I often wish I had a twin sister, someone who 35 me in everything. So why not a clone? Well, the idea 36 be fun but I'm not sure if it would be 37 . I think we would be playing with fire if we let scientists go ahead with 38 cloning. There are so many 39
involved that all research in this area should be strictly controlled.
There are so many arguments 40 cloning that it is difficult to get anyone to consider the possible benefits. I am 41 that it is a technique which could be beneficial. The most obvious use would be for childless 42 . They would be able to have babies with their own genetic material. I don't see what's wrong with that.
Imagine a child 43 up knowing that his or her mother is really a sister or a brother. The emotional 44 on the child would be 45 . Or a child who was cloned from a dead brother or sister. What kind of emotional pressure would they feel, knowing they were made as a replacement for another? The whole idea
46 me!
It's all very good to ban human cloning but scientists should be allowed to 47
research. If they don't, we may 48 important benefits for our society, such as producing body organs. A clone is an 49 copy of a person with the same gene. Therefore, it is the 50 donor for an organ(器官) transplant.

How to get rid of waste is a great problem for the world today. Waste must be treated 16 it does not become a danger to life. 17 , in some countries, waste from factories is still poured straight into rivers. People who use the water from one of these rivers often get 18 . The water may become so polluted that it 19 all the fish in the river. When these rivers finally reaches the 20 , it pollutes the ocean.
In many countries with 21 , human waste is piped directly into the sea without being dealt with. This is not 22 . Although the sea itself can break up the waste, beaches 23 become polluted. 24 scientists suggest people take the waste far out to sea in ships where the wind and waves break it down.
In 1989 an international law was passed to 25 people putting waste into the sea. It is now against the 26 to put anything into the sea nearby. Such rubbish as plastics may not be thrown 27 the sea anywhere. Other waste may be put into the sea, either 19 or more than 40 kilometers from land, 28 the nature of the materials.
The 29 of dealing with waste has become so great that several international organizations have been 30 to protect the world and control pollution.
