A
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.
36. 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． 37．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
38. 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 39．The underlined word “it” in the fifth paragraph refers to________. A．the early life C．immune system
B．an allergic disease
D．something important
40．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
C．Bacteria do good to your kids D．Advantages of owning pets
B
Electrical devices(仪器)could soon use power made by human energy. Scientists say
they have developed an experimental device that produces electricity from the
physical movement of a person walking. British scientist Max Donelan and other scientists in Canada and the United States developed the device.
The device connects to a person’s knee. As the person walks, the device captures energy each time the person slows down. To do this, the device helps with the slowing down movement of the leg. The movements of the walking person push parts of a small machine
that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.
There are several possible uses for the device. Developers say it could help people who work in areas without electricity to operate small computers. The device could also be used in hospitals to operate heart pacemakers(起搏器). It could even be used to assist in the movement of robotic arms and legs.
The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy. But the researchers hope to make a lighter, less costly version. An improved version shou1d be ready in one year.
The developers hope the device will one day help developing countries. Near1y twenty
five percent of people around the world live without electric power.
A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania. He created a bag carried on a person’s back that also produces power from wa1king.
The knee device does not produce as much electricity as the bag. But the bag requires the walker to carry a load of twenty to thirty kilograms. 41. The second paragraph mainly talks about .
A. who developed the device B. how the device works
C. several possible uses for the devices D. how much electricity the device can produce
42. What is the disadvantage of the experimental version of the device?
A. It is too heavy for the walker to bear. B. It is too complex for people to use. C. It is too expensive for most people to afford. D. It will slow down one’s walking speed.
43. Compared with the device designed by Larry Rome, this new device . A. produces power without adding more loads to the walker B. can produce more power in a much shorter time C. needs to be equipped with a battery D. can help the walker wa1k faster
44. From the passage, we can learn that the electrical device can .
A. help housewives operate the washing machine B. make it much easier for us to go online
C. produce more electricity than that invented by Larry Rome D. be applied in medicine to operate heart pacemakers 45. What would be the best title for the passage?
A. First device powered by walking wi1l soon be on the market
B. Advanced technology brings in a new way to operate heart pacemakers C. Device gives new meaning to the idea of power walking D. Human energy will become a main source of electricity

In the fall of 1985, I was a bright-eyed girl heading off to Howard University, aiming at a legal career and dreaming of sitting on a Supreme Court bench somewhere. Twenty-one years later I am still a bright-eyed dreamer and one with quite a different tale to tell.
My grandma, an amazing woman, graduated from college at the age of 65. She was the first in our family to reach that goal. But one year after I started college, she developed cancer. I made the choice to withdraw from college to care for her. It meant that school and my personal dream would have to wait.
Then I got married with another dream: building my family with a combination of
adopt and biological children. In 1999, we adopted our first son. To lay eyes on him was fantastic---and very emotional. A year later came our second adopted boy. Then followed son No. 3. In 2003, I gave birth to another boy.
You can imagine how fully occupied I became, raising four boys under the age of 18. Our home was a complete zoo---a joyous zoo. Not surprising, I never did make it back to college full-time. But I never gave up the dream either. I had only one choice: to find a way. That meant taking as few as one class each semester.
The hardest part was feeling guilty about the time I spent away from the boys. They often wanted me to stay home with them. There certainly were times I wanted to quit, But I knew I should set an example for them to follow through the rest of their lives. In 2007, I graduated from the University of North Carolina. It took me over 21 years to get my college degree!
I am not special, just single-minded. It always struck me that when you’re looking at a big challenge from the outside it looks huge, but when you’re in the midst of it, it just seems normal. Everything you want won’t arrive in your life on one day. It’s a process. Remember: Little steps add up to big dreams..
46. When the author went to Howard University, her dream was to be________ A. a writer B. a teacher C. a doctor D. a judge 47. Why did the author quit school in her second year of college?
A. She wanted to study by herself. B. She decided to look after her grandma. C. She suffered from a serious illness. D. She fell in love and got married.
48. What can we learn about the author from Paragraphs 4 and 5?
A. She ignored her guilty feeling for her sons. B. She was busy yet happy with her family life. C. She wanted to remain a full-time housewife. D. She was too confused to make a correct choice.
49. What does the author mostly want to tell us in the last paragraph? A. Failure is the mother of success.
