Is there intelligent(有智力的) life on other planets(行星)? For years, scientists said "No." or "We don't know." But today this is changing. Seth Shostak and Alexandra Barnett are astronomers (天文学家). They believe intelligent life exists 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 (银河系) ," says Shostak. "And our galaxy, the Milky Way, has at least 100 billion stars. Some planets going around these stars might be similar to 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 Earth--in other solar systems (太阳系).These planets might have intelligent life.

Have beings from space already visited Earth? "Probably not," says Shostak. "It's a long way away. However, intelligent beings may contact us in other way, 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、astronomers B、farmers C、singers D、teachers

（2）、What is the best title for Paragraph 2?

A、The Age and Size of Earth. B、Why Intelligent Life Might Exist. C、Our Galaxy: The Milky Way. D、Earth: The Only Planet with Intelligent Life.

（3）、Why was it hard to look for signs of intelligent life in the universe in the past?

A、There were not any smaller planets. B、There were not any powerful telescopes. C、The astronomers were not interested in them. D、The Milky Way didn't exist at the time.

（4）、Why haven't beings from space visited us yet according to Shostak?

A、They're afraid of us. B、It's a long way away. C、They don't know how to use radio signals. D、They aren't clever.

    Have successful people ever felt sad? Do they have any “secrets” to success? The answers to these questions can be found in US president Barack Obama's “back to school” speech. Here is an excerpt(摘录) from his speech.
    I know that sometimes, you get the sense that you can be rich and successful without any hard work—that your ticket to success is through rapping (饶舌音乐) or basketball or being a TV star, when chances are, you're not going to be any of those things.
    But the truth is, being successful is hard. You won't love every subject you study. Not all the homework will seem completely important to your life right this minute. And you may not succeed at everything the first time you try.
    That's OK. Some of the most successful people in the world are the ones who've had the most failures. JK Rowling's first Harry Potter book was turned down 12 times before it finally came out. Michael Jordan was cut from his high school basketball team, and he lost hundreds of games and missed thousands of shots (投篮) during his career. But he once said, “I have failed over and over and over again in my life. And that is why I succeed.”
    These people succeeded because they understand that you can't let your failures beat you—you have to let them teach you. You have to let them show you what to do differently next time.
    No one's born being good at things. You become good at things through hard work.
    Don't be afraid to ask questions. Don't be afraid to ask for help when you need it. I do that every day. Asking for help isn't a sign of weakness; it's a sign of strength. It shows you have the courage to admit(承认) when you don't know something, and to learn something new.
    And even when you're struggling, even when you're discouraged (泄气), and you feel like other people have given up on you—don't ever give up on yourself. Because when you give up on yourself, you give up on your country.

   The ocean can be a great place to swim and play, it may also be useful in another way. Some scientists think that waves could help make electricity.
   “Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave?” asked Jamie Taylor of the Wave Energy Group in Scotland. “There is certainly a lot of energy in waves.”
   Scientists are working on using that energy to make electricity. The United States and a few other countries have started doing research on wave energy, and it is already being used in Scotland.
   Most waves are created when winds blow across the ocean. “The winds start out by making little ripples (波纹) in the water, but if they keep on blowing, those ripples get bigger and bigger and turn into waves,” Taylor said. “Waves are one of nature's ways of picking up energy and then sending it off on a journey.”
   When waves come towards the coast, people can set up dams(大坝) to block the water and send it through a large wheel called a turbine(涡轮). The turbine can then power an electrical generator(发电机).
   We will never run out of wave power. Besides, wave energy does not create the same pollution as oil and coal do.
   Oceans cover three quarters of the earth's surface. That would make wave power seem perfect for creating energy around the world. But there are some disadvantages that need us to pay more attention to.
   Jamie Taylor said that wave power still cost too much money. He said that its influence on animals in the sea is still unknown. Besides, wave power would get in the way of fishing and boat traffic.
   With more research, “Many of these problems might be solved,” Taylor said. “Finding more energy sources(资源) is very important, for traditional sources of energy like oil and gas may run out some day.”
   In the future, when you turn on a light button, an ocean wave could be providing the electricity!

Every year landslides cause 25 to 50 deaths and $2 billion in damage in the United States. And in December, a single event killed more than 2000 people in the Philippines. Sending workers to stabilize mountainsides using steel bars can help a lot, but it introduces new difficulties because of dust and loosen heavy, dangerous debris from the work. "It's a quite dangerous job," says Giorgio Pezzuto of D' Appolonia, working with eight other companies. Now there may be an answer: a three-ton robot called Roboclimber.
"The idea is to operate a machine far away that can do the stabilizing job without a human being near,"says Pezzuto, manager for the project, which is supported by a European organization. Engineers say that the machine will be faster and cheaper than manual labor. The robot, a large radio-controlled four-legged spider, has cost at least $2 million so far. It should be able to climb mountainsides, drill holes and insert steel bars there. Testing should begin in May.

    Mails, games, music, news, chat rooms and shopping! The Interent is part of our life today. It's easy to get onto the Internet. The only thing we need to do is to use a modem(调制解调器) which is used for connecting a computer to a telephone line. The Internet is changing and growing all the time. More and more people have computers and use the Internet. Using the Internet means surfing the World Wide Web(That's the “WWW” you always hear about). The Internet has a large number of websites(网站). They are the places where you go to get information and do things.
     Where do these websites come from? They are made by web designers. What happens when you click on a word or a picture? You are sent to another page. It's all because of the web designers. Web designers do a lot of work by using a computer programming(程序编制) language.
     Is web design all about computer programming? No, it's about making something new. Web designers must imagine a lot when they are making a website. It must look good and be fun to use. A big part of web design is art. They choose the best pictures and colors to make the website look good. They also write the things that you see on the website. An important part of their job is to share ideas with the website manager about how to design the website well.

Many people have the wrong ideas about pigs. Pigs are actually(买际上) very clean animals. On farms, they live in dirty places, so they become very dirty. But in the wild, pigs keep themselves very clean.

They are also very smart. They may he smarter than clogs. So pigs can learn things from people.

Pigs are very friendly animals. Some people raise (饲养) them as pets. Of course, people raise the smart kind, not the big kind. Small pigs are very cute. And they don't break things in the house. Big pigs usually live outside on the farms, not in people's houses.
