Basketball is still a young game. It is in the winter of 1891, a certain college(学院)was having trouble with its boy students, the weather was so bad that the students had to stay indoors(在室内). Since they could not enjoy their sports outside as usual, they were unhappy, and some of them even got into fights(打架)from time to time.

  Finally, one of the teachers at the college, J. E. Nesmith, was asked to invent a new game for the students, it was not an easy job because such a game had to be played indoors, and the court(场地)was not very large.

  Nesmith thought for a few days and invented a kind of the ball. It was played between two teams. To make a score, the ball had to be thrown into a basket ten feet high above the floor on the wall. At each end of the court there was such a basket. At first, Nesmith had planned to have the ball thrown into a box. As he could not find boxes of the fight size, he had to use fruit basket instead. This is how the game got its name.

  Light travels at a speed which is about a million times faster than the speed of sound. In a second, light travels about 300,000km, but sound travels only 340m. You can get some ideas of this difference by watching the start of a race. If you stand some distance away from the starter, you can see smoke come from his gun before the sound reaches your ears.

  This great speed of light produces some strange facts. Sunlight takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light rays left the moon 1.3 seconds before they reach you. The nearest star is so far away that the light which you can see from it tonight started to travel towards you four years ago at a speed of nearly 20 million km, per minute. In some cases, the light from one of tonight's stars started on its journey to you before you were born.

  Thus, if we want to be honest, we can not say,“the stars are shining tonight.”We have to say,“The stars look pretty. They were shining four years ago but their light has only just reached the earth.”

  Mobile phones have become a problem for middle schools. Some middle schools in Australia have banned(禁止)students from carrying mobile phones during school hours.

  Mobile phone use among children has become a problem for the school this year. Several children have got mobile phones as Christmas gifts, and more students will want them.

  It's important to learn about protecting our environment. Here is a 5R rule for us:

  1. Reduce

  If you want to reduce waste, you should use things wisely(胆智地). A large number of trees are being cut down to make paper. If everyone uses a little paper carelessly and throws it out, soon we would not have any trees left. Other things are also being wasted, and people don't know what to do with the waste in big cities. So it is necessary to reduce the waste.

  2. Reuse

  You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. In a family, you may pass on such clothes to younger brothers or sisters.

  3. Recycle

  Bottles, cans(罐子)and paper can easily be recycled. By doing so we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat(压平)and melted(熔化)and the metal things are made for new coke cans.

  4. Recover

  When you buy a box of apples, there may be a few rotten(腐烂的)apples, you have two choices: one is to throw the whole apples away, or you could cut off the rotten parts and use the good parts. In this way, you are recovering the eatable parts of food.

  5. Repair

  If one of the legs of your table is broken, you can repair it. If you want to change for better ones, it is better for you to sell the old things or give them to other people who can use them after doing something. It is true that North America is a “throw-away” society, but the time has come to change our way of life so hat we can protect our environment. Every one of us should try our best.
