April 22 is Earth Day. Everyone on Earth should care about and protect the earth!
The earth has warmed by about 1°F (華氏度) over the past 100 years, but why and how?
Well, scientists are not quite sure. Maybe the earth gets warmer and warmer on its own. But many scientists say that people are doing many things which makes the earth warmer.
First, greenhouse effect (溫室效應) is a very important reason for the change of the earth. People give out too much energy into the air every year. It makes the earth warmer. Climate (氣候) change is another important reason. Sometimes it becomes too hot and sometimes too cold. Sometimes there is too much rain and sometimes too little. The change of the climate makes the earth warmer. In turn, the warmth of the earth changes the climate, too.
When the earth becomes warmer, there may be more rain and a rise in sea level. It will affect the growth of plants, animals and people. On a Pacific island, 100 people have to move to higher ground because the sea is rising. These people can no longer live on the coast. Before that, two islands without people went underwater in 1999. Scientists say that the seas can rise by nearly one metre by 2100.
People can affect the earth's air, land and water. As for us, we can do many things to protect the earth. For example, we can use fridges less. We can tell more people about protecting the earth.
小題1:Earth Day is probably set for people to ______.

A．learn more about the earth	B．make full use of the earth
C．take better care of the earth.	D．study the warmth of the earth

小題2:We can infer (推斷) from the passage that the reasons for the warmer earth are
______ now.

A．not very clear

B．completely secret

C．well known

D．not given yet

小題3:Greenhouse effect comes from______.

A．sea rising

B．climate change

C．nature's unbalance

D．people's activity

小題4:The passage mainly tells us that ______.

A．there is more rain now	B．we should protect the earth
C．we must stop pollution	D．sea level is getting higher

Water can be a liquid, a solid or a gas. When it is a solid, it can be as hard as stone. When it is a liquid, it can run through your fingers. When it is a gas, you may not see or feel it.
Water can change from a solid to a liquid or to a gas easily. This is why we always have fresh water. Now let us find out how it does. The heat of the sun turns liquid water into gas from the oceans, seas, rivers and lakes. The heat also turns liquid water into gas from the ground, the plants and the animals. Water in the gas rises and turns into clouds in the air.
When the clouds come near a mountain, they rise high. As the clouds rise, they get cooler. The higher they rise, the cooler they become. Then more and more water gas turn into water drops. In this way, the drops of water in the clouds get bigger and bigger. Then they fall to the earth as rain.

In some science fiction movies, evil robots refuse to die, no matter how hard people fight back.
Now science fiction has become science fact. For the first time, scientists have made a robot that can take a beating and keep on going. Scientists from Cornell University made the robot, which looks like a spider with four legs.
Until now, even the most advanced (先進的) robot was almost certain to break down when it was damaged (毀壞). That is because its computer inside simply doesn’t know how to make the machine work after its shape has changed.
To deal with this problem, the scientists put eight motors (發動機) and two sensors (傳感器) that read how the machine is working. They all give signals to the machine’s software. Using this information, the computer can then figure out the machine’s shape at any moment.
The new technology is a big advance in robot-making, scientists say, and it’s far from scary. It may someday help scientists create better artificial (假的) arms and legs and give new freedom to people who lose them. It might also help scientists understand how people and animals figure out their own sense of place in space.
“It has been difficult to design robots that can work well when the environment changes or when it’s damaged,” says Olaf Sporns of Indiana University in US. “With this work, we are nearer to solving this problem.”
小題1:Why do robots easily break down when they are damaged?

A．They cannot repair themselves.

B．The computer has changed a lot.

C．They have no computers inside.

D．The computer cannot work if the robot changes.

小題2:The new technology(技術) allows the robot to .

A．keep working after being damaged

B．tell people where it is

C．do house work for humans

D．remember a lot of information

小題3:The underlined word “them” in Paragraph 5 refers to .

A．sensors

B．robots

C．scientists

D．arms and legs

小題4:How do the sensors in the robot work?

A．They can replace the computer when it’s broken.

B．They help the computer learn the robot’s condition.

C．They can find out where the damage comes from.

D．They can send signals to the person who uses the robot.

When I was a child I never said, "When I grow up, I want to be a CEO," but here I am. When I look back on my career, I realize the road to becoming a CEO isn't a straight, clear path. In fact, no two paths are the same. But whether you want to be a boss one day or not, there's a lot to learn from how leaders rise to the top of successful companies.
As this series of stories shows, the paths to becoming a CEO may be different, but the people in that position(位置) share the qualities of commitment（義務）, work ethic（道德） and a strong desire for building something new. And every CEO take risks along the way—putting your life savings on the line to start a software company or leaving a big business to be one of the first employees at a startup.
I grew up in Minnesota, and learned how to be an entrepreneur（企業家）from my father, who has run a small business for almost 30 years. I went to Georgetown University and tried a lot of business activities in college with success. And I always had a dream job pattern(模式): to walk to work, work for myself and build something for consumers(顧客).
I'm only 29, so it's been a quick ride to CEO. Out of college, I worked for AOL as a product manager, then moved to Revolution Health and ran the consumer product team. In mid-2007 I left Revolution Health and started LivingSocial with several other workmates, where I became a CEO.
Career advice: Don't figure out where you want to work, or even what industry you'd like to work at. Figure out what makes you do so. What gives you a really big rush? Answer why you like things, not what you like doing. . . and then apply it to your work life. Also, just because you're graduating, don't stop learning. Read more books than you did in college. If you do, and they're not, you're really well-positioned to succeed in whatever you do.
小題1:What can we know from the first paragraph?

A．The writer hasn't achieved his childhood ambition.

B．The writer thinks there is some easy way to become a CEO.

C．The writer had an ambition of becoming a CEO in his childhood.

D．The writer believes success stories of CEOs can be beneficial(有益的) to everybody.

小題2:According to the writer, successful CEOs should _____.

A．try not to take risks	B．stay in the same business
C．have a strong sense of creativity	D．save every possible penny

小題3:What can we know about the writer from the passage?

A．He started LivingSocial when he was still a student of Georgetown University.

B．He used to run the consumer product team for AOL.

C．His business activities at college ended up in more failure than success.

D．His father had far-reaching influence on him.

小題4:What does the underlined phrase “figure out” mean? ______.

A．斷定

B．弄清

C．理解

D．領會

小題5:Which of the following proverbs may the writer agree with according to the last paragraph?

A．Well begun is half done.

B．Everything comes to him who waits.

C．Time and tide wait for no man.

D．One is never too old to learn.

Just as in face-to-face communication, there are some basic rules of behavior(行為) that should be followed on the Internet. The basic rule is simple: treat others in the same way you would want to be treated. Imagine how you’d feel if you were in the other person’s shoes.
For anything you’re about to send: ask yourself, “ Would I say that to the person’s face?” If the answer is no, rewrite and reread. If someone in the chat room is rude to you, you needn’t to fire back. You should either ignore(不理睬) the person, or use your chat software to block their messages. Remember to respect the beliefs and opinions of others in the chat room.
Everyone was new to the network once. Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, be kind about it. If you do decide to tell someone about the mistake, point it out politely. At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended(冒犯). You’d better not ask others questions about their age, sex and families. Unless you know the person very well, and you are both comfortable with sharing personal information, or don’t ask such questions.
