Everybody hates rats. But rats may soon be man's new best friends.

    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 space. 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. 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," says a scientist. 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 fantastic. A rat could get into space 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).

Is your food and drink healthy? A lot of ice-cream, hamburgers and cola are unhealthy（不健康的）. Meat is healthy but too much meat is not good for children. Cola and candy are very sweet, and too much sugar is bad for you. Eat the right food and be healthy. Carrots, eggs and sweet potatoes are good for your eyes. Milk, cheese and fish are good for your teeth. A bit tired? Have lots of delicious chicken soup! It is important to remember: eat well, stay healthy, and don't get fat!

The following are some suggestions on healthy eating.

● Eat noodles or rice, not hamburgers.

● Have a good breakfast every morning.

● Drink juice, water, tea and milk, not cola.

● Eat lots of fruit and vegetables, not candy or ice-cream.

Brian was a funny student. He loved watching comedies(喜剧) best and hoped to become a comedy 1  one day. When he heard about a comedy show to be held at his school, Brian decided to 2 . But some students laughed at him. "You are not funny but silly, "Ken, one of his classmates, said to his face. "3  will like what you do, "another boy also said to him loudly. For a moment, he thought about giving up the show. 4  he remembered how much his friends liked his jokes. And also his teachers said he was very 5 , so he decided to prepare for it. 

Brian did a great job at the show and it was a great 6 . His teachers and friends were 7  of him. Even so, Ken told Brian that he was not funny and he would 8  be successful. Brian didn't understand why Ken said so, but he 9  that it had nothing to do with him. He confidently continued to work towards his goal. 

As years went on, Brian met more people like Ken. "10  will do a terrible job, "they said to him. 11 , most people encouraged him and some 12  him to become even funnier. He got a lot of 13  to play a role in movies. His fans thanked him because his comedies made them feel 14  when they were not glad. 

Now Brian is a big comedy star! He is doing what he 15  best. He never cares about those unkind people, and he laughs all day long!
