I havealso discussed it with my best friends, Anna, Sue and Kris. We have different ideas. Annathinks it is the high﹣speed railway; Sue, the shared bike; Kris, the online shopping;and I prefer the Internet.The Internet is just like a net, and it connects us with the world. In the past,it was nearly impossible for people to communicate immediately with people in othercountries. They had to spend a long time to reach their destinations (目的地), and noteveryone could do that. But the Internet has made the impossible possible. Now we can communicate with foreigners online.The Internet also helps us know what is happening around the world, and has madeour life and work easier. In recent years, shopping online is very popular. We can juststay at home and buy what we need online. We can also do online office work and distance education. Besides, we can watch movies, listen to music and even play games to relaxourselves on the Internet.So, I think that the Internet is one of the greatest inventions. It has changedour world! Although there are still many problems with the Internet, they will be solvedin the near future. As a student we should make good use of the Internet!Yours,Martin （1） The letter was written by .A .

Seth Shostak and Alexandra Barnett are astronomers（天文学家）. They believe intelligent life exists（存在） somewhere in the universe. They also think we will soon contact these beings（人生物）.Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is time. Scientists believe the universe is about 12 billion years old." This is 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） have shown that there are at least 100 billion galaxies," says Shostak. "And our galaxy, the Milky Way, has at least 100 billion stars.Some planets going around these stars might be similar to the Earth."In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes（高倍望远镜） allow scientists to discover smaller planets-the size of Mars or the Earth-in other solar systems. These planets might have intelligent life.Have beings from space already visited the Earth?" Probably not," says Shostak. "It's a long way away. However, intelligent beings may contact us in other ways, such as radio signals（信号）. In fact, they may be trying to communicate with us now, but we don't have the right tools to receive their messages. However, this is changing. By 2025, we could make contact with other life forms in our universe and we might help each other."（1） Seth Shostak and Alexandra Barnett are .A . astronomersB . farmersC . singersD . drivers（2） What is the best title for Paragraph 2?A . The Age and Size of the EarthB . Our Galaxy; The Milky WayC . Why Intelligent Life Might ExistD .

Because there were not any powerful telescopes.C . Because the astronomers were not interested in them.D . Because the Milky Way didn't exist at that time.（4） Why haven't beings from space visited us yet according to Shostak?A . Because they're afraid of us.B . Because it's a long way away.C . Because they don't want to see us.D . Because they don't know how to use radio signals.（5） What does the underlined phrase "life forms" in the last paragraph mean?A . Messages.B . Tools.C .
