Most children, even the youngest of children, are delighted to be around cats and dogs. But these pets carry plenty of germs and allergens（过敏原）, prompting researchers to ask: Are cats and dogs really safe for children？
A study finds that, contrary to many parents’ fears, owning cats or dogs does not increase a child’s risk of developing allergies, and in fact, may actually protect them. The study’s lead author, Dr. Dennic Ownby of the Medical College of Georgia, says that even he was “very surprised” by the results. Ownby and colleagues followed more than 470 children from birth to age 6 or 7, comparing those exposed to cats and dogs during their first year of life to those who were not.
By using skin-prick(刺) tests for detecting common allergies, the researchers found that, contrary to what many doctors had been taught for years, children who had lived with a pet were not at greater risk.
Even more remarkable, children who had two or more dogs or cats had an even greater reduction, up to 77 percent, in risk of allergies. Researchers suggest this protective effect may be the result of early exposure to lots of bacteria that are carried by dogs and cats. Exposing young children to these bacteria helps" exercise" their immune systems early in life so that they're better able to resist allergic diseases later.
There's something very important in that first year of life when the immune system is developing that we can retrain it away from an allergic response, said Dr. William Davis.
And while researchers are not encouraging parents to buy dogs or cats just to reduce a child’s allergy risk, they say if a family already has one or more animals, there's no need to get rid of them. Why do the researchers feel “very surprised” by the results of the study?
| A．Because the results are contrary to their expectation． |
| B．Because so many children are playing with cats and dogs． |
| C．Because parents are so much worried about their children． |
| D．Because children with animals may develop allergies easily． |
Compared with children who have pets，those who haven’t ______.
| A．will lose the chance to develop immune system |
| B．may suffer allergic diseases more often |
| C．will reduce the harm from bacteria |
| D．can keep doctors away |

| A．pets are ill-treated by their owners |
| B．less families would like to own cats and dogs |
| C．keeping pets is a good way to keep children healthy |
| D．the results of the study can make families with pets feel at ease |

| A．the early life | B．an allergic disease |
| C．immune system | D．something important |
What may be the best title of the passage?

Have you ever had a day when everything seemed to go wrong, and nothing seemed to go right? Not too long ago I was having one of those days. I was discouraged, weary, and plain sad. My focus was on me. After all, no one else was experiencing the same trials I was.
I expressed my upset state to my mother, hoping for some pity. Instead, she said, “I heard Jamie was having a difficult day too. Why don’t you make her some cookies and take them to her this afternoon?”
I didn’t really want to, but decided that I didn’t want to go back to my other problems just yet. I made the cookies and arranged them on a little plate. Then I made a card with a sunflower on it and wrote a small note of empathy.
That afternoon I dropped by my friend’s house. I went to the door and rang the bell. Soon, Jamie came to the door and looked at me in surprise for the unexpected visit. Before she could say anything I rushed, “ I heard you were having a hard day and decided to bring you something. I hope your day goes better.” The look that came over Jamie’s face was one that I could never put into words. It was as if a darkened sky was suddenly lit with the golden rays of the sun; it was as if in that small act, her day was brightened.
I got back into the car and for some amazing reason; I felt a lot better myself. That day I experienced the truth that James Barri attempted to describe, “ Those who bring sunshine to the lives of others cannot keep it from themselves.”Which of the following is the best title for the passage?

When you visit America, you will see the word Motel on signs and notice boards. It is made up of “motor” and “hotel” and it is really a hotel for people who arrive by car (how-ever, you don’t need a car to stay at one). You have to pay when you arrive for your room, which usually has a bath. Meals are not provided, but there will certainly be a cafeteria (自助餐馆). Americans eat a lot of salads and sandwiches. Along the main roads there are a lot of motels. Each tries to offer more than next. Some provide television in every bedroom; others have swimming pools; and so on. Motels are especially useful when you are in the country, far from a town or city. You will also find them in the big National Parks.
In these great National Parks, you may meet guests you don’t expect to see. An American friend told me a little story. In the middle of a moonless night she heard strange noises outside her motel window in the Yellowstone National Park in Wyoming. Thinking it might be a thief, she jumped out of bed, opened the door and crept towards a dark shadow(阴影）. As she got close, she saw the thief. She was dreadfully frightened: it wasn’t a human thief — it was a big black bear. The bear was turning over some empty tins with its paw, looking for tasty bits of food. My friend decided to leave that particular thief alone!
There are also, of course, places called “rooming houses”, where they receive lodgers (房客). You will see such signs as Tourists or Rooms Rent, and you could try one of these.

“Hey, Sheba,” she said, “I've got no time for you now, but I'll take you out as soon as I get back from tennis club.” Then she noticed Sheba seemed to be coughing or choking. Obviously, she could hardly breathe. Immediately, Joanne realized she would have to take her to the vet (兽医).
When she got there, the vet was just about to close for the day. Seeing the state of Sheba, Dr. Sterne brought her quickly into his office.
“Listen, doctor, I'm really in a rush to get to a meeting, can I leave her with you, and go and get changed? I'll be back in ten minutes to pick her up, and then I'll take her on to the meeting with me. Is that OK?”
“Sure.” said the doctor.
Joanne made the quick trip back to her house in a couple of minutes. As she was once moreentering the hallway, the phone by the door began to ring.
“This is Dr. Sterne,” said an anxious voice. “I want you to get out of that house immediately, ”said the doctor's voice. “I'm coming round right away, and the police will be there any time now. Wait outside!”
At that moment, a police car screeched (发出尖锐的声音)to a stop outside the house. Two policemen got out and ran into the house. Joanne was by now completely confused and very frightened. Then the doctor arrived.
“Where’s Sheba? Is she OK?” shouted Joanne.
“She’s fine, Joanne. I took out the thing which was choking her, and she’s OK now. ”
Just then, the two policemen reappeared from the house, half-carrying a white—faced man, who could hardly walk. There was blood all over him.
“My God, ” said Joanne,“how did he get in there? And how did you know he was there?”

Many people who work in London prefer to live outside it, and to go in to their offices or schools every day by train, car or bus, even though this means they have to get up early in the morning and reach home late in the evening.
One advantage of living outside London is that houses are cheaper. Even a small flat in London without a garden costs quite a lot to rent. With the same money, one can get a little house in the country with a garden of one’s own.
Then, in the country one can rest from the noise and hurry of the town. Even though one has to get up earlier and spend more time in trains or buses, one can sleep better at night and during weekends and on summer evenings, one can enjoy the fresh, clean air of the country. If one likes gardens, one can spend one’s free time digging, planting, watering and doing the hundred and one other jobs which are needed in a garden. Then, when the flowers and vegetables come up, one has the reward of one who has shared the secret of Nature.
Some people, however, take no interest in country things: for them, happiness lies in the town, with its cinemas and theatres, beautiful shops and busy streets, dance-halls and restaurants. Such people would feel that their life was not worth living if they had to live it outside London. An occasional walk in one of the parks and a fortnight’s (two weeks) visit to the sea every summer is all the country they want: the rest they are quite prepared to leave to those who are glad to get away from London every night.Which of the following statements is NOT true?
| A．People who like country things prefer to live outside the city. |
