译林牛津英语八年级下册Unit 3阅读理解随堂练习（无答案）The internet is becoming important in our life. How much do you know about it? What is the internet? The internet is a large, worldwide collection of computer networks, A network is a small group of computers put together. The Internet is many different networks from all over the world. These networks are called the Internet. Once you have learned to use the Internet, you can have a lot of interest on the World Wide Web.What is the World Wide Web?The World Wide Wed has been the most popular development of the internet: The Web is like a big electronic book with millions of pages. These pages are called homepages.You can find information about almost anything in the world on these pages. For example, you can use the Internet instead of a library to find information for your homework. You can also find information about your favorite sport or film star, talk to your friends or even do some shopping on the pages. Most pages have words, pictures and even sound or music.What is e-mail?Electronic mail (E-mail) is a way of sending messages to other people. It's much quicker and cheaper than sending a letter.If you want to use e-mail, you must have an e-mail address. This address must have letters and dots and an (meaning "at"). This is what an address looks like: e-mail@. Write a message, type in the person's e-mail address, then send the message across the Internet. People don't need to use stamps, envelopes or go to the post office since the invention of the internet. Quick, easy and interesting, that's the Internet!1.The Internet is.A. a big computerB. a small group of computersC.lots of computer networksD.the world Wide Web2.The World Wide Web is like.A.an electronic bookB.homepagesC.an electronic pageD.air interesting picture3.What does "talk to your friends on the pages" mean?

It is a new network（网络）after 1G, 2G, 3G and 4G and it can connect everyone and everything together. 5G networks will cover/many cities in China soon. 5G means super-fast data （数据）speed, One can download a two-hour movie for fewer than 10 seconds, and it is making our hives more and more convenient.5G will make self-driving cars possible. For safety, self-driving cars need super-fast data transmission（传输）to communicate with their nearby environment. 5G is just what makes self-driving cars achieve this/Eyen airplanes will become "smart" in the near future. Passengers will be able to use 5G networks in the air to connect to the Internet or place orders for food and drinks.5G will be a big help for students who take online classes. Many people live in poor areas in the world where there are no schools. But with 5G, this will change. Students all over the world will be able to see places like the Great Wall without leaving their rooms.It will be also easier for doctors to treat patients remotely by 5G. It means caring for patients from far away.The fats listed above are only a part of what 5G will make possible and popular. Just as in the early days of the Internet in the 1990s, few could see how it could change or lie and the world. The same will surely be true of 5G.

They hope computers can help them improve （提高）their studies in school. Yet many of the children use computers to play games, to watch video or to sing Karaoke, instead of studying.

His family were very poor farmers, and there was never enough to eat. Frank decided he did not want to be a farmer. He took a short business course, and went to work as a salesman in a large city.Wool worth realized he had a natural skill for displaying goods to arouse people's interest, but he soon learned something more important. One day his boss told him to sell some odds and ends（/」\商品）for as much as he could get. Frank put all these things on one table with a sign which said: FIVE CENTS EACH. People fought and pushed to buy the things and the table was soon cleared.Soon afterwards, Wool worth opened his own store, selling goods at five and ten cents. But he had another lesson to learn before he became successful. That is, if you want to make money by selling low - price goods, you have to buy them in large quantities directly from the factories. Once, for example, Wool worth went to Germany and placed an order for knives. The order was so large that the factory had to keep running 24 hours a day for a whole year. In this way, the price of the knives was cut down by half.By 1919 , Wool worth had over 1,000 stores in the USA and Canada, and opened his first store in London . He made many millions and his name became famous throughout the world.

"I spend about half an hour reading newspapers every day," said 15-year-old Gao Ming from Beijing. "I'm interested in things happening at school." School news is just one kind of news story in newspapers. There's also world news: from international problems to pop stars.Read the newspaper carefully, well find different types of articles on the pages:News stories - these stories are about events.
