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 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.
1.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.
2.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
3.It can be inferred from the passage that ______.
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
4.The underlined word “it” in the fifth paragraph refers to________.
A.the early life
B.an allergic disease
C.immune system
D.something important
5.What may be the best title of the passage?
A.How to protect your kids from allergies
B.Your pets may be helping your kids

I was born into a family of five children. As the youngest child, I didn’t have many new clothes. Though my parents worked very hard, we could hardly make ends meet. The only time we would receive new clothes was at Christmas.
The family across the street lived a much better life. They just had two daughters and they were often seen wearing new dresses. The younger girl named Anna was of my age. One afternoon, she walked on the street wearing a beautiful white dress. She looked like an angel in that dress. I, together with many little girls, followed her. We just couldn’t keep our eyes off her dress. We all wished we would have such a dress one day!
That day, after coming back, I told my mom that I wanted a dress like that. My mom frowned(皱眉) she thought such a beautiful dress like that must cost an arm and a leg, but my mom kept that in mind. She worked five days a week at that time, but when Christmas was getting close, she worked even on every Saturday.
However, several days before Christmas, I changed my mind. It was Anna’s birthday that day and I was invited to her home with some other girls. After that party, I asked if I could try on her white dress. “Of course,” she said, “and you can take it if you like it.” I couldn’t believe my ears. How could she give such a beautiful dress to someone else? After trying it on, I knew why.
The dress looked beautiful, but it was uncomfortable to wear. As a matter of fact, my back was quite itchy(痒的) after I put it on. From that day on, I stopped admiring what others had. They may not be as good aswe think.

Humans are naturally drawn to other life forms and the worlds outside of our own. We take delight in the existence of creatures and even whole societies beyond our everyday lives.
This sense of wonder is universal. Look at the efforts that scientists have made to find out whether life of some kind exists on Mars, and the popularity of fantasy literature or movies like The Lord of the Rings. This sense of wonder draws us to each other, to the world around us, and to the world of make-believe. But have we gone so far in creating worlds of fantasy that we are missing the pleasure of other worlds that already exist all around us?
Human beings, as biologists have suggested, possess an inborn desire to connect with and understand other life forms. However, people, especially in big cities, often lead rather isolated lives. In a study of British schoolchildren, it was found that children by age eight were much more familiar with characters from television shows and video games than with common wildlife. Without modem technology, a small pond could be an amazing world filled with strange and beautiful plants, insects, birds, and animals. When we lack meaningful interaction(交互) with the world around us, and sometimes even with our families and friends, we seek to understand and communicate with things that exist only in our imaginations or on a computer screen。
The world of make-believe is not necessarily bad. But when the world of fantasy becomes the only outlet(出路) for our sense of wonder, then we are really missing something. We are missing a connection with the living world. Other wonderful worlds exist all around us. But even more interesting is that if we look closely enough, we can see that these worlds, in a broad sense, are really part of our own.
1.The popularity of The Lord of the Rings proves
A. the close connection between man and the fantasy world
B. the wonderful achievements of fantasy literature
C. the fine taste of moviegoers around the world
D. the general existence of the sense of curiosity
2.What can we infer from the underlined sentence in Paragraph 3?
A. People are far less familiar with the world of fantasy.
B. The world around us could serve as a source of wonder.
C. The world of fantasy can be mirrored by a small and lively pond.
D. Modern technology prevents us from developing our sense of wonder.
3. If our sense of wonder relies totally on the world of make-believe, we will
A. fail to appreciate the joy in our lives
B. be confused by the world of make-believe
C. miss the chance to recognize the fantasy world
D. be trapped by other worlds existing all around us
4. What is the main purpose of the passage?
A. To show us the hidden beauty in our world.
B. To warn us not to get lost in the fantasy world.
C. To argue against the misuse of the sense of wonder.
D. To discuss the influence of the world of make-believe.

“Most children,” Asher Svidensky says, “are a little afraid of golden eagles. However, Kazakh boys in western Mongolia start learning how to use the huge birds to hunt for foxes and hares at the age of 13.” Svidensky, a photographer and travel writer, shot five boys learning the skill as well as the girl, Ashol Pan. “To see her with the eagle was amazing,” he recalls. “She was a lot more comfortable with it, a lot more powerful with it and a lot more at ease with it.”
The Kazakhs in western Mongolia are the only people that hunt with golden eagles, and today there are around 400 practising eagle hunters. Ashol Pan, the daughter of a famous hunter, may well be the country’s only girl hunter.
They hunt in winter, when the temperatures can drop to -40℃. A hunt begins with days of traveling on horseback through a snow mountain or ridge (山脉) giving an excellent view of prey for miles around. Hunters generally work in teams. After a fox is discovered, riders rush to frighten it into the open, and an eagle is released (释放). If the eagle fails to make a kill, another is released.
“The skill of hunting with eagles,” Svidensky says, “lies in bringing an unexpected force of nature under control. You don’t really control the eagle. You can try and make her hunt an animal, and then it’s a matter of nature. What will the eagle do? Will she make it? How will you get her back afterwards?”
Svidensky describes Ashol Pan as a smiling, sweet and shy girl. “Ashol Pan stands for something about Mongolia in the 21st century,” says Svidensky. “Everything there is going to change and is going to be redefined (重新定义), and the possibility is amazing.”
1.What makes Asher Svidensky much surprised?
A. The colorful and powerful eagles.
B. The special way of hunting by the Kazakhs.
C. The wonderful performance of Ashol Pan.
D. The young age of Kazakh eagle hunters.
2.What does the underlined word “prey” in the third paragraph mean?
A. The scenery to be enjoyed.
B. The creature to be caught.
C. The option to be argued.
D. The future to be expected.
3.What can we infer from the fourth paragraph?
A. Man can overcome nature.
B. All efforts will pay off one day.
C. Making use of existing resources is important.
D. Never think about controlling others.
4.What’s the passage mainly about?
A. A photographer and travel writer’s traveling experience.
B. A girl eagle hunter in Mongolia.
C. The true life of the eagle hunters in Mongolia.
D. The future of the traditional way of eagle hunting.

From Monday until Friday most people are busy working or studying, but in the evenings and on weekends they are free to relax and enjoy themselves. Some watch TV or go to the movies; others take part in sports. It depends on individual interest. There are many different ways to spend our spare time.
Almost everyone has some kind of hobby. It may be anything from collecting stamps to making model airplanes. Some hobbies are very expensive, but others don’t cost anything at all. Some collections are worth a lot of money; others are valuable only to their owners.
I know a man who has a coin collection worth several thousand dollars. A short time ago he bought a rare fifty-cent piece worth $250!He was very happy about his purchase (buying) and thought the price was reasonable. On the other hand, my youngest brother collects matchboxes. He has almost 600 of them but I doubt if they are worth any money. However, to my brother they are extremely valuable. Nothing makes him happier than to find a new matchbox for his collection.
That’s what a hobby means, I guess. It is something we like to do in our spare time simply for the fun of it. The value in dollars is not important, but the pleasure it gives us is.
1.The word “individual” in the first paragraph most probably means ________.
A.different B.strange C.secret D.one’s own
