He came up with the idea of the World Wide Web in 1989 while he was working in Switzerland.Berners-Lee made it possible for everyone to use the Internet,not just universities and the army.He designed the first “web browser”,which allowed computer users to access documents (文件) from other computers.From the moment on,the web and the Internet grew.Within five years,the number of Internet users rosefrom 600,000 to 40 million.The Internet has made thousands of millionaires (百万富翁),but Berners-Lee is not one of them.Everyone in the world can access the Internet using his World Wide Web system.He now works as a lecturer at Massachusetts Institute of Technology in Boston.1Usually we access the Internet through .A.a radioB.a computerC.a TV setD.a recorder,人们通常通过电脑上网。

B(导学号57140020)As some cities start driving beggars from their major streets,some of the smarter ones have found a safer,more comfortable place to carry on—the Internet.These “Web beggars” go online wi th a sad story,and send out emails asking for money,according to a recent Beijing News report.The paper published one example from a reader who had received it.It said,“I’m from Chengdu.Dad died when I was a kid and Mum is seriously ill.Mygirlfriend has just dumped(丢下)me.I am so depressed that I cannot leave home.Would you please help me with 10 yuan for a meal?” The sender left the name Li Dan and a bank account number.A reporter later contacted Li Dan through QQ,a Chinese Internet chat service.He said that he was 21 and had recently dropped out of college.“I started begging by the Internet last December,just for fun,” he said.“But when I got the first 10 yuan in January,I decided to become a full-time web beggar.”Li said he knew about 10 other web beggars in Chengdu.They all stayed at home to write emails and could probably send over 1,000 per day.They would exchange experience and thoughts over QQ or beggar websites.The story got some reaction from the public.Some saw it as a fresh idea but others suspected(怀疑)that it was just another form of cheating.In related news,Nanjing,the capital of Jiangsu Province,began to ban begging in eight of its major districts on Monday,according to local media.That caused a heated discussion about whether it violated (妨碍)beggars’rights.Most people supported the policy,repeating the old line that most beggars were not real beggars and that they annoyed people constantly,according to a newspaper poll(计票).5What does “web beggars” mean?A.The beggars who have a net.B.The beggars that ask for money on the Internet.C.The beggars that like the Internet.D.A website which is controlled by some beggars.,是指通过网络乞讨的乞丐。

interested.They can read your message when they have time,and read only as much as they want to.They can reply at their convenience,and you can read what they have to say at your convenience.E-mail is

感顿市安乐阳光实验学校Unit 3 Section ⅠWarming Up & Reading—PrereadingⅠ.阅读理解ACody Hartley, 11, has tirelessly raised money to get a very important piece of first aid (急救)equipment put in at her primary school, secondary school and karate (a Japanese fighting sport) club. She has spent eight months so far trying to raise the money needed.The money Cody has been collecting is for defibrillators (除纤颤器)—a kind of medical machine that gives the heart an electric shock to make it start beating again after a heart attack.“I went on a firstaid course with my karate club. I learned how to use a defibrillator and how important they are for saving lives，” Cody told MailOnline.A couple of weeks later she was reading in the local paper about a 12yearold boy who had a heart attack during his swimming lesson, “Although he received good first aid, there was no defibrillator and he didn't make it，” she says. “I couldn't stop thinking about that.”Then Cody started to do some research about them online and realized how impo rtant they are. “They're not just for old people who have heart attacks—there are also hundreds of children out there who die from heart conditions，” she says.She wanted to get one for her primary school, so she did a 20mile sponsored (为慈善目的发起的) walk with her dad. She did other sponsored events, raised money at car boot sales (汽车后备箱集市) on a Sunday morning and got five of her friends to help her pack bags at a supermarket.She adds, “In all I've raised over ￡2,000. I want to keep going and I'll not stop un til all the schools in Yorkshire get defibrillators.”【文章大意】本文是一篇记叙文。

Unit 3 ComputersIn a way computers can be considered a technological revolution. Because they have “artificial intelligence”， they can simplify difficult sums,“think”logically and solve any difficult mathematical problem. With the development of the network,computers have become very important in communication, finance and trade, and people all over the world can share their knowledge with others through the World Wide Web. Nowadays boys and girls use their mobile phones to surf the Internet. In order to explore the moon and Mars, computers have already been put into space rockets. In a word, computers can nearly deal with most problems in life. With the help of computers, the goal of human race will be turned into reality.However, just as a saying g oes, “Every coin has two sides.” Personally, if you don't use computers properly, something uncomfortable will happen. For example, computer games programmed by operators are so wonderful that a lot of young people love them very much. They even play the games day and night without going to school. As a result, they failed in their lessons. Sometimes if you download something, viruses which can make your computer break down will arise.Anyhow, if you have a computer, your life will be filled with happiness.在某种程度上电脑可以被看作是一次技术革命。

It makes us wonder ... why can't scientists find a cure (疗法) for the common cold if they can send a man to the moon? The answer is easy. There are hundreds of kinds of cold viruses (病毒) out there. You never know which one you will get, so there isn't a cure for each one.When a virus attacks your body, your body works hard to get rid of it. Blood rushes to your nose and brings congestion (堵塞) with it. You feel terrible because you can't breathe well, but your body is actually “eating” the virus. Your temperature rises and you get a fever, but the heat of your body is killing the virus. You also have a runny nose to stop the virus from getting to your cells. You may feel miserable,_but actually your wonderful body is doing everything it can to kill the cold.Different people have different ways of dealing with colds. In the United States and some other countries, for example, people might eat chicken soup to feel better. Some people drink warm water. Other people take medicine.There is one interesting thing to note—some scientists say taking medicine when you have a cold is actually bad for you. The virus stays in you longer because your body doesn't have a way to fight with it and kill it. Bodies can do an amazing job on their own. There is a joke, however, on taking medicine when you have a cold.
