Everybody hates rats. But in the earthqu...

Everybody hates rats. But in the earthquake capitals of the world—Japan, Los Angeles, Turkey—rats will soon be man’s new best friends.

What happens after an earthquake? We sent in rescue 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. Christian Linster at Cornell University, New York, says, “‘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(电)!

The “rat project” is not finished, but Julie Ryan of International Rescue Corps in Scotland says, “It would be fantastic. A rat could get into spaces we couldn’t get to and a rat would get out of it 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 world earthquake capitals, rats will become man’s best friends because they can    .

A.take the place of man’s rescue jobs

B.find the position of people alive who are trapped in buildings

C.serve as food for people alive who are trapped in buildings.

D.get into small spaces

2.In doing rescue jobs,        .

A.rats smell better than dogs

B.dogs don’t need to be trained to smell people

C.robots’ sense of smell can be affected by other smells around

D.rats can see in the dark and smaller than robots

3.Rats have all the following advantages EXCEPT that       .

A.they are more fantastic than other animals

B.they are less expensive to train than dogs

C.they don’t need electricity

D.they are small and can get into small places

4.After reading the passage we can know       .

A.at present rats have taken the place of dogs in searching for people

B.the “rat project” has been completed

C.people are now happy to see a rat in a building

D.now people still use dogs and robots in performing rescues

 

1.B 2.C 3.A 4. D 【解析】 试题分析:1.B 推理题。根据文章第二段说明老鼠也可以用来解析救援任务,来确定受伤的人的位置等,故B正确。 2.C 细节题。根据第四段第二行‘Robots ’noses don’t work well when there are other smells around.说明机器人的嗅觉有时候会受到其它气味的影响。故C正确。 3.A 细节题。根据文章倒数第二段最后两行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(电)!说明BC正确。根据第二段后两行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.说明D也是老鼠的优势。A文章没有提及。 4.D 推理题。根据文章最后一句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).说明现在还没有投入使用,是将来的事情,故使用将来时。故D正确。 考点:常考科普类短文阅读

If you are planning on traveling, there are few simple rules about how to make life easier both before and after your journey.

First of all, always check and double-check departure (出发) time. It is surprising how few people really do this carefully. Once I arrived at he airport a few minutes after ten. My secretary had got the ticket for me and I thought she had said that the plane left at 10:50. When I arrived at the airport, the person at the departure desk told me that my flight was closed. Therefore, I had to wait three hours for the next one and missed an important meeting.

The second rule is to remember that even in this age of credit cards (信用卡), it is still important to have some local money in cash (现金). Once I arrived at a place at midnight and the bank at the airport was closed. The only way to get to my hotel was by taxi but because I had no dollars, I offered to pay in pounds instead. “Listen! I only take real money!” the driver said angrily. You can imagine how terrible I felt at that moment.

The third and the last rule is to find out as much as you can about the weather at your destination(目的地) before you leave. I feel sorry for some of my workmates who travel in heavy suits and raincoats in May, when it is still fairly cool in London or Manchester, to places like Athens, Rome of Madrid, where it is already beginning to get quite warm during the day.

1.Where is the writer most probably from?

A.Britain

B.The USA

C.Italy

2.When the writer found he had no dollars to pay the taxi driver, he      .

A.asked the driver to give him a free ride

B.offered to pay in pounds

C.gave the driver some fake(假) money

D.tried to pay by credit card

3.Generally, in May the weather in London is     .

A.warm and dry

B.cold and dry

C.hot and wet

D.cool and rainy

4.The writer mainly tells us      .

A.how to make life easier

B.how to be well prepared for a trip

C.how to enjoy ourselves on trip

D.how to schedule our trip

Sarah Williams went to a boarding school.  Here is one of the

letters she wrote to her parents from the school.

Wentworth Girls' School

Beachside

July 20th

Dearest Mom and Dad,

I'm afraid I have some very bad news for you. I have been very naughty and the school principal is very angry with me. She is going to write to you. You must come and take me away from here. She does not want me in the school any longer.

The trouble started last night when I was smoking in bed.  This is against the rules, of course. We are not supposed to smoke at all.

As I was smoking, I heard footsteps coming towards the room. I did not want a teacher to catch me smoking, so I threw the cigarette away.

Unfortunately, the cigarette fell into the waste-paper basket, which caught fire.

There was a curtain near the waste-paper basket which caught fire, too. Soon the whole room was burning.

The principal phoned for the fire department. The school is a long way from the town and by the time the fire department arrived, the whole school was in flames. Many of the girls are in the hospital.

The principal says that the fire was all my fault and you must pay for the damage. She will send you a bill for about a million dollars.

I’m very sorry about this.

Much love,

Sarah

P. S. None of the above is true, but I have failed my exams. I just want you to know how bad things could have been!

1.Why did Sarah write home?

A.To tell her parents about the fire.

B.To ask for a lot of money.

A.She wanted to worry them.

“You are quite right,” his wife replied, “and most of the things he’s never returned.”

“What I want to know,” her husband said, “is why he can’t buy the things he needs like everyone else.”

“Because people like us are foolish enough to lend him what he needs.” she replied. “As long as we are willing to lend, he’ll keep on borrowing.”

“Then we’ll never lend him anything again.” Mr. Wu said. “The next time he asks to borrow something, I’ll say no.”
