Everybody hates rats. But rats may soon be man’s new good friend.
What happens after an earthquake? We send in rescue(援救)dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
How does it work? First, the rat is trained to smell people. When this happens, the rat’s brain gives a signal(信号). This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
Although there are already robots which can do this job, rats are better. “Robots’ noses don’t work well when there are other smells around. Rats are good at that.” Rats can also see in the dark, they are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity!
The “rat project” is not finished, but a scientist says, “It would be great. A rat could get into spaces we couldn’t get to, and a rat would get out if it wasn’t safe.” Perhaps for the first time in history, people will be happy to see a rat in a building (but only after an earthquake, of course).

In the past, going to a piano teacher was the only way to learn how to play the piano. You could have one lesson a week. If you didn’t have private(个人的) lessons, you could still learn piano, but you would have to learn it by yourself. This was easy for some, but very difficult for most. However, with technology as it is today, there is at last another way that you can take piano lessons. You can take an online course.
An online course can save you lots of money. If a private lesson costs 30 or 40 dollars per week, just think about how quickly that adds up. You can take a complete online course in piano by spending a small part of the money that you would pay for taking weeks of private lessons. Also, private lessons are only usually one hour per week. If you have questions during the rest of the week, or if you forget something that your teacher said, you will have to wait for your next lesson to continue your learning. However, online piano courses are quite different.
With an online piano course, you can work at your own pace(进度). You can also take as many lessons per week as you’d want, or go back and listen to your last lesson if you have forgotten anything. Most adults who want to learn how to play the piano enjoy being able to go back and listen to lessons they watched before. It can give you a good idea of what you were doing right, what you were doing wrong, and what you should be doing before the next lesson.
Of course, if you need someone to sit beside you and give you instant feedback(及时反馈) while you are playing, you are not suggested to choose an online course. But most adult learners think they can get their own type of feedback by watching the course again and again.
小题1:       is not mentioned in the passage to learn to play the piano.
A.Going to a piano teacher        B. Asking experts for information   C. Teaching oneself
小题2:Going to a piano teacher is much more        than having an online piano course.

小题3:If you choose an online piano course, you can          .
A. ask questions whenever you want
B. watch the lessons whenever you’d like
C. get some advice while you are playing the piano.
小题4:Most adults like to go back and listen to the lessons again because         .
A. they needn’t spend any extra money
B. they can ask some questions
C. they can know what they were doing right, what they were doing wrong
小题5:How many advantages of an online piano course have been introduced in the passage?
A. 2                           B. 3                         C. 4

Have you seen Avatar？It’s a popular movie this year. It is three-dimensional(3D), so you may have to wear a special pair of glasses to see it. The 3D glasses make the images(图像) from the movie look like they are coming straight at you.
More and more 3D movies are coming to theaters. 3D TV sets have been produced in Japan now. Three-dimensional technology can make TV and movies more exciting. But people with eye problems may get headaches if they spend too much time watching 3D movies.
When we look at an object(物体), each eye sees it at a different angle(角度). Our eyes send the two images to our brain(大脑), and the brain puts them together. That’s how we see depth(深度). So when we watch a 3D movie, one film projector(投影机) projects a left eye image and the other projects a right eye image. 3D glasses allow us to see a different image in each eye.
There are a lot of people walking around with very less serious eye problems. Under normal situations, the brain can adjust to their eyes so they can see things normally.
But when they are watching a 3D movie, the images projected to their eyes can’t be put together by their brain. So the brain needs to work harder at reading the images. That makes it easier for these people to get headaches.
Dr John Hagan, an eye doctor in Kansas City, said some people who do not see depth normally cannot see in 3D at all.
小题1:When people want to watch a three-dimensional movie, they need          .
A. a ticket                  B. a pair of 3D glasses             C. an earphone
小题2:Three-dimensional technology uses         film projector(s) to project one movie at the same time.
A. one                     B. two                         C. three
小题3:According to the passage, if we look at an object by only one eye, we can’t judge the       excatly.
A. image                   B. angle                         C. depth
小题4:Which statement is TRUE according to the passage?
A. In the near future, people can enjoy 3D movie by watching TV at home.
B. Whenever you wear a 3D glasses, you can see objects more clearly.
C. People who have something wrong with their brain can’t read the images of 3D movie.
小题5:The main idea of this passage is            .
A. how to use 3D glasses to watch a 3D movie.
B. 3D glasses make the movie seem alive
C. not everybody can enjoy 3D movies.

Now more and more people in the world are getting fatter. This troubles them a lot. （1）Experts(专家) say that it has a lot to do with our eating habits.
Our eating habits are very important for good health and a strong body. Most of us like eating sweets and ice cream better than vegetables and rice. Sweets and ice cream are not bad for us if we eat them at the end of a meal. （2）If we eat them before a meal, they may take away our appetite(食欲).
It’s important for us to eat our meal in the same period each day. When we feel worried or excited, we may not want to eat. A long time ago, in England, some judges(法官) often decided whether a man was telling the truth by giving him some dry bread. If the man could not swallow(吞) the bread, it meant that he wasn’t telling the truth. Because when a man is worried about something, he will have trouble in swallowing anything dry, because he loses his appetite.
小题1:Are more and more people getting fatter in the world?________________________       ___
小题2:Do most people like eating sweets or rice?_______________________            ________
