The Internet is becoming important in our life. How much do you know about it? The following questions and their answers will help you to know more about the Internet.

What is the Internet?

The Internet is a large, world-wide collection (聚集) of computer networks (网络). A network is a small group of computers put together. The Internet is many different kinds of networks from all over the world. These networks are called the Internet. If you have learned to use the Internet, you can have a lot of interest on the World Wide Web (网) .

What is the World Wide Web?

The World Wide Web has been the most popular development of the Internet. It is like a big electronic (电子) 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 favourite 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 (点) and an @ (means “at”). For example: Lily @ Yahoo.com. Write a message, type a person’s e-mail address, and then send the message across the Internet. People don’t need to use stamps, envelopes or go to the post office because of the invention of the Internet. Quick, easy and interesting — that’s the Internet.

How much do you know about the universe? In the huge universe, there is the Galaxy and many other galaxies. In the Galaxy, there is the Solar System and lots of other stars. In the Solar System, there is the sun, the earth and seven other planets. As we know, the eight planets go around their star -----the sun. In our Earth-moon System, the moon goes around the earth. And because our earth keeps turning around the sun all the time, we have day and night. When our part of the earth turns to the sun, it is day. When our part of the earth turns away from the sun, it is night.

Just because the moon is closer to the earth than the sun, it looks much bigger than the sun. The sun is big enough to give out very strong light. The moon itself can’t give any light at all, but it looks quite bright, too. In fact, the light from the moon comes from the sun. Although , the moon looks much bigger and brighter than the sun and other stars, in fact, all the stars are much bigger and brighter than the moon. They look smaller than the moon also because they are farther away from us. It’s clear that big things will look smaller when they are farther , and small things look bigger when they are nearer.

So far, we have traveled to many other planets in the universe. But scientists haven’t discovered any living things on any other planets. Scientists haven’t discovered any other planets with a good environment. They aren’t sure if there is any water and air for living things to live on other planets. People always ask the question: Is there anyone out space? Our scientists haven’t got a clear answer either. Some people think it will be a secret for a long time. But we believe we can solve* the problem some day.

Exploring our Solar System and the universe is a great national project to some countries. Our Chinese scientists are also trying to send spaceships with astronauts to those planets and even the universe. At 9:00 a.m. on October 15th, 2003, a Chinese astronaut called Yang Liwei was sent up to space. He stayed there for hours and got back to the earth at 6:00 a.m. the next day. It was the first time for Chinese to have a space travel.

A. Because in fact the moon is bigger than the stars.

B. Because the moon is father from the earth than the stars.

C. Because the stars is nearer our earth than the moon.

D. Because we are closer to the moon than the stars.

3.In Para.4, what does the underlined word it refer* to ?

A. the people’s question　　 B. the scientists’ answe

C. the universe　　 D. the environment

4.According to the passage, we can infer that 　　　　　 .

A. not all the planets go around the star in the Solar System

C. it is hard work for scientists to discover if there is any living things out space

D. few countries are trying to explore the universe

The haze season is back. How much do you know about haze? Haze can also be called “Smog”. The word “smog” is from the words “smoke” and “fog”. It is a kind of air pollution(污染) mostly because of cars and factories.

Smog will do great harm(伤害) to your health. It can make you cough and have skin and eye problems. It seems that we can do nothing to stop it, but only wait until the wind blows all the smog away. However, there are some easy ways to stop it hurting you. Here are some of them.

1. Don’t do exercise in the open.

Exercising in the open makes you breathe(呼吸) deeply, and you will take in the particles(颗粒物) deep into your lungs.

2. Stay indoors and keep the air clean.

If you can, just stay in your room and keep the doors and windows closed. Remember to air your room twice a day, you can open the window at noon or at night for half an hour.

3. Wear a mask.

Paper and cotton masks can not help you in the haze weather. Some special masks, such as N95 masks, can keep you from breathing in the particles in the air.

4. Change your diet.

Scientists find that vitamin A, C and E can greatly help protect your eyes, nose and lungs. So eat more green vegetables and fresh fruit every day. What’s more, do not eat food with too much fat.
