    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).

(1)、In the writer's opinion, rats may become man's new friend because         .

A、they can be food for people B、they can help rescuers to find living people C、they are lovely D、they can completely replace man's rescue jobs
(2)、What does the underlined word “this” mean?

A、An earthquake. B、The rat has smelled a person C、The rat has smelled that someone is alive D、The rat has found a robot.
(3)、Which of the following is NOT true?

A、Rats don't need electricity. B、Rats are better than robots when smelling. C、Rats are as clever as radios. D、Rats can see things in the dark when doing rescues.
(4)、Why does the “rat project” sound great according to the passage?

A、Because rats can get into very small spaces B、Because rats have better noses than dogs. C、Because rats don't like robots D、Because rats are brave.
(5)、Which is the best title of this passage?

A、Ways of saving people B、Rats and robots C、After earthquake D、Rats for rescue

    Zhalong is a nature park in Heilongjiang in Northeast China. It is one of the world's most important wetlands. The area provides food and homes for wildlife. It is an ideal home for different kinds of plants, fishes and birds.

    Many birds live comfortably in Zhalong Nature Park all year round, while some only stay for a short time. There are many fish in the wetlands, and the birds can easily catch them for food. Zhalong Nature Park is an important living area for the rare red-crowned cranes. There are not many red-crowned cranes in the world. Some of them live in Zhalong.

    Some people want to change the wetlands to make more space for farms and buildings. This means that there will be less and less space for wildlife.

    More and more birds are in danger because they do not have enough living space. Many of them died. The Chinese government wants to protect these endangered birds, and they can be safe in Zhalong.

    Every year a lot of tourists go to Zhalong to watch birds. This year members of our Bird Watching Club are going to study the different kinds of birds in Zhalong and the changes in their numbers. The study will begin next month.

    We do a bird count once a year. We are now inviting the second school students to help. We need more people to help us count and do something to help the birds. Many people do not understand the importance of the wetlands. We hope this information will help them understand it and make them actively take action to protect wildlife.
