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. 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.

What’s the most important thing for you to have in your life? Somebody says hard-work, others suggest knowledge, love and luck.

If you arrange the 26 English letters alphabetically(按字母表的顺序) and use numbers to represent each of them, for example, 1 for a, 2 for b, 3 for c…, you can change an English word into a number. So hard-work becomes 8+1+18+4+23+15+18+11=98, meaning 98 is its mark; knowledge: 11+14+15+23+12+5+4+7+5=96, while love :12+15+22+5=54, and luck: 12+21+3+11=47, a small mark. None of these words can give one a full mark. What about money or prayer(祈祷)? They can’t , either.

Then what else? Don’t be worried. You can always find an answer to a problem in your life, when you change your way of looking at things or doing things, or your attitude. Yes, attitude is the word. See for yourself: attitude: 1+20+20+9+20+21+4+5=100, a full mark.

Different attitudes lead to different ways of life. Most times people hope for a better life. It is possible that you will have a change for the better after you have changed your attitude.

When you change your manner and become friendly towards others, you’ll meet more smiling faces. In the same way, if you take a positive(积极地) attitude towards failure(失败), you’ll find you may have more chances to succeed.

1.We can use ________ to represent “money”.

A. 72B. 71C. 70
