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(jìn)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(fā)動機(jī)) 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(shù)) 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．robotsC．scientistsD．a(chǎn)rms 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.

小題1:D
小題2:A
小題3:D
小題4:B

試題分析：這篇文章講述了為了解決機(jī)器人一旦被損壞就不能工作的問題，科學(xué)家給機(jī)器人里面放了八個發(fā)動機(jī)和兩個傳感器，這個新的技術(shù)還能幫助科學(xué)家給人們創(chuàng)造出更好的假肢。

New rules and behavior standards(行為規(guī)范) for middle school students came out in March. Middle schools are going to use a new way to decide who the top students are. The best students won’t only have high marks. They will also be kids who don’t dye(染) their hair. The following are some of the new rules.
Tell the truth. Have you ever copied someone else’s work on an exam? Don’t do it again! That’s not something an honest student should do. If you have played computer games for two hours in your room, don’t tell your parents you have done homework.
Do more at school. Good students love animals and care for other people. April is Bird-loving month in China. Is your school doing anything to celebrate? You should join! In that way, you can learn more about animals and how to protect them. When more people work together, it makes it more fun for everyone.
Have you ever quarreled with your teammates when your basketball team lost? Only working together can make your team stronger. Be friendly to the people you are with. Try to think of others, not only yourself.
Be open to new ideas. Have you ever thought that people could live on the moon? Maybe you’ll discover Earth Ⅱ some day. Don’t look down on new ideas. Everyone’s ideas are important. You should welcome them, because new ideas make life better for everyone.
Protect yourself. Has someone ever taken money from one of your classmates? Don’t let it happen to you. If you have to go home late, you should let your parents know.
Use the Internet carefully. The Internet can be very useful for your studies. But some things on the Internet aren’t for kids, so try to look at web pages that are good for you. You can use the web for fun or homework. Can’t you find any good websites for children? Here are some: Http:// kids.eastday.com, Http://www. chinakids. net. com, http ://www. cycnet.com.
根據(jù)短文內(nèi)容，選擇最佳選項(xiàng),將其標(biāo)號在答題卡上涂黑。（每小題2分，共10分）

Some people like to get up early, but some do not. In fact, it is really good for us to get up early every day. Maybe those who don’t like getting up early will not believe this, but it is true. Scientists made a survey(調(diào)查) in about one thousand people, and then they found that early rising people had less disease(疾病) than late rising people, and early rising people also look healthier than late rising people, and so on.
So we may know early rising is helpful in more than one way. Firstly, it helps to keep us healthy. We all need fresh(新鮮的) air. And air is the freshest early in the morning. Besides(此外), it is useful to do morning exercises.
Secondly, early rising helps us in our studies. In the morning we learn more quickly and find it easier to understand what we learn.
Thirdly, early rising can give us a plan of our work for the day. We cannot work well without a good plan.
Fourthly, early rising gives us enough time to get ready for our work, such as to wash our hands and faces and eat our breakfast.
Late risers may find it difficult to form(形成) the habit(習(xí)慣) of early rising. They have to make an effort(努力) to do so. As the English proverb(諺語) says, “Early to bed and early to rise makes a man healthy, wealthy and wise.”
小題1:We may read this passage in a _______ magazine.
A．healthB．sportsC．musicD．travel
小題2:Early rising people are _______ than late rising people.
A．fatterB．thinnerC．healthierD．cleverer
小題3:Air is the freshest ______ according to the passage.
A．in the morningB．in the afternoonC．in the eveningD．a(chǎn)ll day
小題4:Which of the following is NOT the result(結(jié)果) of early rising?
A．People can get ready for their work.
B．People can get fresh air.
C．People can learn things more quickly and better.
D．People can have enough food for breakfast.
