Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血压) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.
Any owner will tell you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people— half of them pet owners —while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed (放松)around pets, says Allen, who thinks it may be because pets don't judge.
A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about 11 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn't lose any more weight than those without dogs but, say researchers, got more exercise overall-mostly with their dogs - and found it worth doing.

Health is the most important thing in the world. Nothing is more important than health. If we take away our money, houses, or even our clothes, we can still survive. — 71 That is why we always try to eat in a healthy way and exercise regularly.
How can we keep healthy? In order to eat healthily, I usually avoid eating food high in fat, like French fries or cookies, which are junk food. 72 I eat a lot of vegetables and fresh fruit which are full of vitamins (维生素).
73 Taking exercise every day helps us build a strong body. Regular exercise is an important part of keeping me healthy.
What’s more, I think friends are an important part of one’s health. 74 I always feel better when I am with friends than I am alone. When I am with friends, I always laugh. Laughing is also in important part of health. It’s good to stay with my friends.
By eating properly and exercising regularly, I can keep my mind as well as my body happy. These things sound easy to do, but not many people can manage them. 75

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).

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.

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

Mr. and Mrs. Wu were fed up with their neighbor. He was always borrowing things from them.
“It’s not right.” Mr. Wu said to his wife one evening. “At some time or another that man has borrowed nearly everything we have. Almost every day he comes over to borrow something.”
“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.”
“We must have a good reason for saying no,” his wire said, “and we must always try to be polite to him. We don’t want to make an enemy of the man.”
