Most people agree that a pet adds joy to a person’s life. Scientists are now finding that having a pet may keep its owner . And good health may add years to a person’s life.
Scientists have been the tie between pets and health for years. In 1990, a study was done with people aged 65 and older. It that pet owners went to the doctor less than people __ pets. Do pets make people ? Are people able to handle their everyday lives better? Alan Beck, who is a researcher, says that the answer to the questions is yes, then having pets may be a good idea.
Can pets also help people live longer? Rebecca Johnson did a study to . Johnson teaches nurses how to care for people. Her study shows that having pets may cause people to more slowly.
The human body makes many chemicals. Some of the chemicals make people feel . Others make people feel bad. In Johnson’s , levels of the “good” chemicals when people were around pets while levels of the “bad” chemicals went down. The good __ seemed to slow the aging of cells. If this is , maybe people should spend more time with their . Then people might feel better and longer.
You might be allergic（过敏的） to pets. Or you may not want to 57 a pet. Never fear. A robotic, or computer pet may be just the thing for you.
Scientists are testing computer pets, like the robotic dog AIBO. They want to see if __ pets can help people the way dogs do.

For millions of years, coral reefs（珊瑚礁）have provided homes and food for thousands of different living things. Fish and sea birds share the reef with other creatures. Now these beautiful places are in danger. 1. Scientists have found that more than one-fourth of the earth’s coral reefs have been ruined so far. Another quarter will disappear in ten years’ time. Unless things change, all of the remaining reefs may die within your lifetime.
Some people think that coral is stone because of its rough（粗糙的）, hard surface. But coral is an animal. Tiny polyps（水螅体）form the coral reefs. 2. These colors come from the algae（海藻）living inside the coral. Billions of coral polyps stick together. New ones grow on the dead ones. This happens year after year. Over time, the coral builds up a reef. The reef rises from the ocean floor until it almost reaches the sea’s surface. It takes coral 500,000 years to build a huge reef. 3.
The coral reefs have been harmed mainly in three ways. The first factor is pollution on land. The pollutants run with rainwater into streams and rivers, which carry the poisons into the ocean. 4. So they will be easily infected with diseases. Another cause is people. People have broken off pieces of coral, which they want to sell or keep as souvenirs. People have dropped sticks of dynamite（炸药）into the water to catch more fish. The worst problem is the heating up of the oceans. Higher ocean temperatures kill the important food source for the coral—the algae, the tiny greenish-gold water plants that live on coral. 5. The coral turns white and dies. Scientists call this coral bleaching（珊瑚白化）. The bleached part of the coral reef cannot recover.
A. They come in many different colors.
B. However, humans have taken less than 100 years to destroy it.
C. This has blown up parts of the reefs.
D. When the algae die, the coral loses both its food and its color.
E. So are all the sea plants and animals that depend on them.
F. Chemicals from the poisons kill reefs or make them weak.
G. Many of them might not even last that long!
Darek Fidyka, a 38-year-old Bulgarian, had been paralyzed (瘫痪的) from the chest down for four years after a knife attack. Scientists from Britain and Poland took cells from his nose, transplanted (移植) them into his back and re-grew his spinal cord (脊髓). Now he can walk and even drive a car. The doctors were delighted but said it was the first step in a long journey.
The breakthrough came after 40 years of research by Professor Geoff Raisman, who found that cells had the possibility to repair damage to nasal (鼻腔的) nerves, the only part of the nervous system that constantly re-grows. “The idea was to take something from an area where the nervous system can repair itself and put it into an area that doesn’t repair itself,” Professor Raisman said.
Polish doctors injected (注射) the nasal cells into Mr Fidyka’s spinal cord above the injury and used some nerves from his ankle to form a bridge across the damaged tissue. The nasal cells appear to have caused the spinal nerves to repair themselves.
Professor Raisman achieved this with rats in the late 1990’s, but this is his greatest success. “I think the moment of discovery for me was Christmas in 1997 when I first saw a rat, which couldn’t control its hand, put its hand out to me. That was an exciting moment, because I realized then that my belief that the nervous system could be repaired was true.”
Doctors chose the easiest case for their first attempt—it might not work for others. But there is a real sense of hope that an idea once thought impossible has been realized.
David Nicholls, who helped provide money for the breakthrough, said information about the breakthrough would be made available to researchers across the globe.
“What you’ve got to understand is that for three million paralyzed people in the world today, the world looks a totally brighter place than it did yesterday,” he said.
1. Why did Professor Geoff Raisman choose cells from the nose?
A. The nervous system in the nose can repair itself.
B. Cells from the nose can be easily transplanted.
C. The nervous system in the nose has more cells.
D. Cells in the nose are able to re-produce rapidly.
2. How did the operation work for Darek Fidyka?
A. The nervous system in the spinal nerves can repair itself.
B. The nerves from his ankle cured the patient of the injury.
C. The nasal cells re-produced and spread over very quickly.
D. The nasal cells helped the spinal nerves to repair themselves.
3. What made Professor Geoff Raisman begin to believe the nervous system can be repaired?
A. His former study with other people. B. His operation on a paralyzed patient.
C. His sudden thought about Christmas. D. His unusual experience with a sick rat.
4. David Nicholls’ words suggest that _______.
A. the world will become a better and brighter place
B. paralyzed people of today have the hope of recovery
