Which Is More Useful?
Thomas is in Grade Two now. He goes to school from Monday to Friday. After school he must do some housework. He helps his parents on the farm(农场) on Saturdays and Sundays. So he doesn't have any time to play football in the daytime. He often plays with his friends in the moon(月亮).
It's five in the afternoon. School is over. Thomas goes home and cooks for his family. After dinner he sees his friend Paul near his house and asks him to play football. The boy looks at the sky and sees the moon. Then he asks, "Which is more useful, the sun or the moon?"
"I think the moon is," says Thomas. "We need light(光线) in the evening, but we can not see the sun, but the moon!"

Some countries are better than others at looking after the environment. In Europe, Germany(德国) and northern European countries work very hard to improve the environment. The people in Germany put their rubbish into different bags--paper in one bag, plastic in another. Laws do not allow people to burn too much coal.
In the l970s, as people learned more about environmental problems. The "Green" movement(运动) began and soon spread all over Europe. The "Green" movement tries to get governments to protect the environment. It collects information about how industry is damaging(毁坏) the environment and tells newspapers.
You might see aliens in books and movies. They look strange. They are very smart. They travel in spaceships.
But are there really aliens in space? British scientist Stephen Hawking, 68, thinks so. He says that people should not look for aliens. He thinks they are dangerous. On a new British TV program, Hawking says, "It is quite possible that there are aliens in space. They might live in big spaceships. They have used up all the resources（资源）from their home planet. "He thinks such aliens are sure to get resources from Earth and then go away. They may bring troubles to Earth, too.
The earth is a (行星)and it goes around the sun. Seven others also go around the sun. (没有一个)of them has an (环境)like that of the (地球), so scientists do not think they will find life on them. The sun and its planet are called the (太阳的)system, and ours is a small part of a much larger (群, 组)of stars and planets, called the (星系).
Scientists have also (发现)many others in the (宇宙). They are very far away and their (光)has to travel for many years to reach us. So how large is it? It is impossible to imagine.
The Earth is a planet. It and seven other planets go the Sun. We (call)the eight planets and the Sun the solar system. first planet, next to the Sun, is Mercury(水星). It is 58 million (kilometer)from the Sun. Venus(金星)is the second planet from the Sun, and (we)planet, the Earth, is the third. It is 150 million kilometers from the Sun.
Jupiter(木星), Saturn(土星), Neptune(海王星)and Uranus(天王星)are all (big)than the Earth, Venus, Mars and Mercury are smaller than the Earth.
Animals, trees and humans can only live the Earth-the other planets in our solar system do not have air water. Do any planets in other solar systems have (life)? We don't know about it.

—Have you ______it under the sofa?
When I was in Grade 9, a new boy came into my classroom. He was short and thin. He walked up to the teacher and told her, very seriously, that he was new. His name was Christian. He sat down, took a look at me, and then looked away. I didn't think he was very nice and I was sure he wasn't the type I would like to become friends with.
During that year, I didn't talk to him much but he smiled at me when our eyes met, always shyly. He never ate lunch with anybody, and he never talked to anybody but me.
But one day I joined those unkind kids who were making fun of him. We made fun of him though I thought it was wrong.
"Haven't you got any friends?" a kid asked Christian, who had walked past us alone, head down.
"No, he hasn't got any friends. He's too stupid and shy," I said. Then Christian looked up at me with the saddest eyes I had ever seen. I felt very sorry at that moment.
That night, I couldn't sleep because I couldn't get Christian's face out of my mind. In the weeks that followed, he never met my eyes in class and never smiled at me. It was really hard for me to decide to write him a note asking him to forgive（原谅）me. But I did.
The next day in class, I passed him a note. About five minutes later, I turned and saw tears in his eyes. "You will never realize what your apology（道歉）means to me, Jimmy," he said to me. "I hope we can become friends."
We had lunch together that noon and we had the best talk I had ever had. Over the years at high school, we were close friends.
Thinking back, I realize that, if I didn't apologized, I would never know what a lovely person he was.
Apologies can really change your life, so never miss the chance to tell somebody you are sorry.
—But I (see) it many times!
—He (go) to the cinema with Julie.
