---Why don't you go to the lecture-room and listen to the talk?

　---I hear there isn't ________in it.

When you look up into the sky at night, have you ever felt that your eyes are playing tricks on (捉弄) you? It seems that the stars are moving all the time.

Actually, there is nothing wrong with your eyes. This twinkling effect is called scintillation (交光). Scintillation happens because of air movements in the earth’s atmosphere (大气). Light is “bent (弯曲的)” when it travels through different parts of the earth’s atmosphere. As the air in the earth’s atmosphere is moving all the time, the light from the stars looks as if it is moving too.

The same thing also happens to things on the ground. On a very hot and shiny day, if you look at the road, the image in the distance is not clear and things move slightly. You can also see the same effect if you drop a rock into water. The rock appears a little unclear under the moving water.

This twinkling effect causes a lot of problems for astronomers (天文学家) since they cannot observe the stars clearly. A telescope (望远镜) was sent into space so that the air movements in the atmosphere could be avoided (避免). It took a long time to build the space telescope but finally in 1990, a huge space telescope called the Hubble Space Telescope was successfully sent into space. Since then, astronomers have many important observations that have helped people understand space better.

I often hear some students say English is difficult, and it gives them a headache. So they can't learn it well. But English is very easy for me. I'm good at it. I'm very glad to tell you something about how I study English.

First, I think an interest in English is very important. When I was in Grade One, we had a new subject-English. It was fresh for me. I was interested in it, so I worked hard at it. Soon we had an English exam and I got a very good mark. How happy I was! After that, I learned English harder and harder. Our English teacher often teaches us English songs, the songs sound nice. I often think how interesting English is!

Second, I think English is a foreign language. I should learn it well in the following ways: Listen to the teacher carefully, speak bravely, read aloud and have a good vocabulary. Then practice again and again, never be tired. And I also have a good habit: Asking whenever(不论何时)I have a question, I must make it clear by asking our English teacher. How happy I am when I understand!

Besides this, I often read English stories, jokes and easy novels. From these I know English is not only interesting, but also useful. They help me understand a lot of things. So to do more reading is an important way to learn English well.

And I also do some exercises from our class magazines, and I often write English diaries. English has become a close friend of mine.

Now I have learned English for more than two years. I always keep the first position in our school. From these words, I hope every student can learn English well.

What to do if you don't feel popular？

●Try to take part in activities. Call your friends. Plan to do something. The worst feeling is staying home alone, because it makes you feel even more lonely.

●Try to make new friends. Choose friends carefully, not just because you think they're popular. And remember, making good friends takes time. Choosing a popular person to be friends with is okay. If they are nice.　

●Be yourself. If you want to become friends with someone who's popular, don't make yourself into someone you are not just to impress that person.

●Be nice. Be friendly. Be outgoing. But don't overdo it！Talk to trusted friends if you are feeling really bad. Or you might want to write it down in a diary.
