Millions of stars are travelling about in space. A few form groups which travel together, but most of them travel alone.
And they travel through a universe which is so large that one star seldom comes near to another. For the most important part each star makes its journey in complete loneliness, like a ship on an empty ocean. The ship will be well over a million miles from its nearest neighbour. From this it is easy to understand why a star seldom finds another anywhere near it.
We believe, however, that some two thousand million years ago, another star wandering(漫游) through space, happened to come near our sun just as the sun and the moon raised its tides(潮汐) on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; A large tidal(潮汐的) wave must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and thrown off small parts of itself into space.
These small pieces have been going round the sun ever since. They are the planets.

What is your favorite color? Do you like yellow, orange, or red? If you do, you must be an active person who enjoys life. Do you like blue? Then you are probably quiet, shy, and would rather follow than lead.
Colors do influence our moods (情绪). A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand, black is depressing(令人压抑的). There was a black bridge over the Thames River, near London. The number of people who killed themselves on that bridge used to be larger than on any other bridge in the area -- until it was repainted green.
Light and bright colors make people not only happier but also more active. In the factory, the workers will work better, harder, and have fewer accidents when their machines are painted orange rather than black.

We each have a memory(记忆力). That’s why we can still remember things after a long time. Some people have very good memories and they can easily learn many things by heart, but some people can only remember things when they say or do them again and again. Many of the great men of the world have got unusual memories.
A good memory is a great help in learning a language. Everybody learns his mother language when he is a small child. He hears the sounds, remembers them and then he learns to speak. Some children are living with their parents in foreign countries. They can learn two languages as easily as one because they hear, remember and speak two languages every day. In school it is not so easy to learn a foreign language because the pupils have so little time for it, and they are busy with other subjects, too.
But your memory will become better and better when you do more and more exercises.

If you take away many sentences from somebody's written work as your own without permission, it's called plagiarism,but if you take the knowledge from a piece of work by another and change the words, then it's not plagiarism. This is the difference between using the Internet and plagiarism. If you are given homework to work out math problems, then you should use your brain without a computer! If the teacher asks you to learn something about a famous literary person, you can use the computer. If you take down the main important information of the task, it’s OK. However, if you run to the computer to do your thinking for you all the time, you don’t exercise your brain and you will forget how to work out a problem. By using a computer, students may get a useful answer fast, to finish homework, but when they have to face an exam, they will not be ready for it.
Though teachers say finding or buying homework answers online is not many in schools, an interview with school students shows only 10% hopes to finish their holiday homework by themselves. They complain that the homework is too much for them to finish. Besides, many of students have to go to all kinds of training classes during the holiday. These take away much of their time for doing homework. So they want to find or even buy answers online or copy each other's homework. Students should learn that being a student is about getting skills, but not just getting quick, cheap "answers" for homework problems. I mean we should use the computer properly.
小题1:If you want to look up some information about something or somebody, you____.
A.should work it out by yourself
B.can turn to a computer for help
C.must discuss it with your teacher
D.will meet problems with plagiarism
小题2:Which belongs to plagiarism according to the text?
A.Answering questions in our own words.
B.Buying homework answers on the Internet.
C.Copying others’ written work without permission.
D.Doing our homework with the help of a computer.
小题3:Which is NOT the reason why the students hope to buy homework answers online?
A.The answers are cheap and quick.
B.They can exercise their brains all the time.
C.They have to go to all kinds of training classes during the holiday.
D.They have too much homework to finish.
小题4:What's the author's attitude towards using the computer for homework answers?
A.Using it for math problems.
B.Using it all the time for the homework.
C.Using it to get some information on the answers.
D.Using it when there's too much homework to finish.
Your parents always tell you that a good education is the key to a bright future. The promise you made to finish your schooling has been completed. Another few years in some college classroom just doesn’t sound too attractive; so what are your choices? Let’s see, Choice One—You can live with your parents and do nothing. Or Choice Two—You could get yourself a job. Of course, there are other choices, but for this little discussion, we’ll just suppose that they aren’t related (有关的).
OK, so Choice Two is obviously going to be more effective. You will finally enter the real world. Well, hopefully high school helped to give you some kind of an idea of what type of job you would like to enter. If not, then it would be a good idea to speak with an expert working in the field you may be interested in before you jump into a job that you won’t like. Gaining knowledge can be good by helping you find the job that you will enjoy doing. Another reason to get some valued things before working. Internships (见习) or volunteering are usually a good place to start.
If you are ready to begin a job after high school, you will save money from college cost and happily making a living in your chosen jobs. From another point of view, jumping into the workforce (劳动力) is sometimes the only way to see for yourself if you are ready to work a 40-hour week yet. If you decide that full time work is not what you are ready for, then this may advise that you should go back to a university and get a certificate.
