I do not believe there are aliens. It's true that the universe is quite huge. And maybe you think that there should be other intelligent life in the universe. But we are quite intelligent and have explored many parts of the universe. If aliens were there, we would have found them by now. I'm Philip. Since there is life on our planet, I believe there is life on other planets as well. It's very possible that there is another planet like ours. Life might exist like ours on that planet. I don't think aliens live among us, but I believe there is life somewhere in our universe. They may be some kind of animals. And they may be as smart as us. I'm Rock. It is hard to say whether there are aliens or not. It depends on how far we are willing to look into the future. I'm not talking about the present time, but the very distant future. Perhaps our grandchildren in 100 or 200 years might explore space together and discover more about aliens. ( )11. Why doesn't Ruby believe there are aliens in the universe？ A.

The whole Greentown was covered by dark clouds. Chris was on his way home. It started raining all of a sudden. And soon it rained cats and dogs. 　　Suddenly he saw a UFO appearing from the clouds above. In no time it landed on the road. Three aliens came out from the spaceship. To Chris's surprise, he could understand their language. Their plan was to take all the trees away from the Earth and plant them on their own planet. Not wasting a moment, Chris called his friends. Those aliens pointed to a tree. A blue light shot out from their hands, making the tree disappear. Soon, Chris's friends arrived. They tried to scare those aliens away by throwing stones, but it didn't work. Luckily, Mr Goon, the fat inspector (巡视员)of the area, arrived. With a frightened look on his face, he shot at those aliens. One of them pointed his finger at Mr Goon. To everyone's amazement, Mr Goon became as thin as a stick. Everybody laughed. Suddenly, Anna, Chris's friend, ran towards the aliens, shouting at the top of her shrill (尖厉的) voice. Those aliens got frightened and vanished along with their spaceship. The kids were excited because they saved their planet. ( )16. What did the aliens plan to do? A. To kill all the people on Earth. 　 B. To live on Earth. C. To plant their trees on Earth. 　 D.

D C Is there intelligent life on other planets? For years, scientists have said “No.” or “We don't know.” But today it's changing. Seth Shostak and Alexandra Barnett are astronomers (天文学家). They believe there's intelligent life somewhere in the universe and we will soon communicate with these beings. Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is TIME. Scientists believe the universe is about 13 billion years old. “It's long enough for other planets to have intelligent life,” say Shostak and Barnett. The second reason is SIZE—the universe is huge. “Tools like the Hubble telescope (哈勃望远镜) show there are at least 100 billion galaxies (星系),” says Shostak. “ Our galaxy, the Milky Way, has at least 100 billion stars. Some planets going around these stars might be similar to the Earth.” Long ago, looking for signs of intelligent life in the universe was hard.Now, powerful telescopes let scientists discover smaller planets, of the size of Mars or the Earth, in other solar systems. These planets might have intelligent life. Have beings from space visited the Earth? “Probably not,” says Shostak. “It's a long way away. However, intelligent beings may contact us in other ways,such as with radio signals. Actually, they may be trying to communicate with us, but we don't have right tools to receive their messages. However, it's changing. Soon, we will make contact with other life forms in our universe and we might help each other.” ( )21. How old is the universe according to scientists? A. About 13 million years old. B. About 100 million years old. C. About 13 billion years old. D. About 100 billion years old. C ( )22. What does Paragraph 2 mainly talk about? A. The age and size of the Earth. B. Our galaxy—the Milky Way. C. Why there may be intelligent life on other planets. D. The Earth—the only planet with intelligent life. C ( )23. Why was it hard to look for signs of intelligent life in the universe in the past? A. Because astronomers were not interested in it. B. Because scientists didn't find the Milky Way at that time. C. Because scientists were not allowed to discover planets. D. Because there were not any powerful telescopes. D ( )24. Why have beings from space NOT visited us yet according to Shostak? A. Because they are afraid of us. B. Because it is a long way to travel to the Earth. C. Because they don't want to visit us. D. Because they don't know how to use radio signals. B ( )25. What does the underlined phrase “life forms” in the last paragraph refer to? A. Messages. B. Radio signals. C. Astronomers. D. Intelligent beings.

Here are the results. 40% of my classmates believe aliens exist and live on faraway planets. And 35% say there are no aliens and humans are alone in the universe. 25% are not sure and think there should be more evidence to prove that aliens exist. In my opinion, the universe is huge, so it's hard to believe there are only living things on Earth. I hope we can receive messages from outer space and make friends with aliens one day. THANKS! $
