Once, a circle lost a piece of its own. The circle wanted to be whole, so it went around looking for its missing piece. But it was incomplete, so it could only roll very slowly. It enjoyed the flowers and the sunshine along the way. It talked with worms. It found lots of different pieces, but none of them fit. So it left them all by the side of the road and kept on looking for the missing piece.
Then one day the circle found a piece that fit perfectly. The circle put the missing piece into itself. It could be whole with nothing missing. It was so happy and began to roll. Now that it was a perfect circle, it could roll very fast, too fast to see flowers or talk to worms. It realized how different the world was when it rolled so quickly. It felt so sad that it stopped, left its found piece by the side of the road and rolled away slowly.
Sometimes we are perfect when we lose something. A man who has everything is a poor man in some ways. He will never have hopes, dreams or something better. He will never know someone loves him or someone is giving him something he has always wanted or never had.
We couldn’t be perfect, but we must be brave enough to love, strong enough to forgive, kind enough to share happiness with others and clever enough to know there is enough love around us and then we can always live a wonderful time in our lives.

When Christie Andrews was born, she weighed less that half of one kilogram. Her heart was the size of a large coin. Her mother said Christie was so small that she could hold her in the palm of one hand.
Christie couldn’t breathe without a machine to give her oxygen. If she had been born 20 years earlier, she would probably have died at once. She needed two operations, but she survived without serious damage.
Twenty years ago , 90% of all premature(早产) babies died. Today, doctors manage to save four out of every five, because they have better machines for breathing and better ways to feed the babies.
But saving Christie’s life cost more than $ 400,000. In some cases, doctors spend 1 million dollars saving a single child. The parents usually don’t have enough money to pay. The government, an insurance company or the hospital picks up the bill. Even after a baby goes home from the hospital, it may require medical care.
Some people think it makes more sense to spend money saving 10 adults who have cancer or other diseases than saving one small baby. But nobody wants to be the doctor who has to tell parents to their faces, “Sorry, I won’t save your new child.”
【小题1】 Parents don’t pay their babies’ hospital bills because        .

A．they don’t have enough money

B．they would rather save cancer patients

C．doctors don’t care if the babies die

D．it makes more sense to have a bigger baby

【小题2】The true cost of saving a baby may be even more than 1 million because        .

A．oxygen machine are expensive

B．the baby may require medical care after it leaves the hospital

C．doctors always charge more than they should

D．four out of five premature babies can now be saved

【小题3】From the story we know that saving a cancer patient        .

A．is easier than saving a baby	B．is harder than saving a baby
C．is cheaper than saving a baby	D．is more common than saving a baby

【小题4】The main idea of the article is        .

A．doctors must never decide whether to save babies or cancer patients

B．doctors are able to save premature babies, but the cost is very high

C．having a premature baby was cheaper and safer 20 years ago

D．Christie survived because the hospital paid her bills

Scientists are placing robotic dogs in the homes of lonely old people to test whether they can improve the quality of life for humans. Alan Beck, an expert(专家) in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study on the effect of robotic dogs on old people’s depression (沮丧) , physical activity, and life satisfaction.
In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, scientists will collect baseline data(数据) for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the scientists will review the data to test if it has produced any changes in the life of its owner.
“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady. “When I’m watching TV, he’ll stay in my arms until he wants down. He has his own mind.”
The AIBOs respond to certain orders. The scientists say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
“At the beginning, it was believed that no one would relate(与……相关) to the robotic dog, because it was metal and not furry.” Beck says. “Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters’ blood pressure, oxygen levels or heart rhythms(心律). AIBOs may even one day have games that can help stimulate(刺激) older people’s minds.”
【小题1】The purpose of Beck and Edwards’ study is to _____________.

A．understand human-animal relationship

B．make lonely old people’s life better

C．find the causes of old people’s loneliness

D．improve the animal-assisted research

【小题2】 In the research, the old people are asked to _____________.

A．note the activities of AIBOs

B．keep AIBOs at home for 12 weeks

C．record their feelings and activity

D．study the collected information

【小题3】What does the underlined word “removes” mean?

A．moves again

B．is movable

C．doesn’t need

D．need

【小题4】What is the better point of AIBO than live dogs?

A．It is easier to keep at home.

B．It can help the disabled people.

C．It responds to all the human orders.

D．It can watch TV with its owner.

【小题5】The writer seems to suggest that the future robotic dogs may__________.

A．cure certain diseases	B．keep old people active
C．change people’s ideas	D．look more like real dogs
