Heads up! Across the country, sports injuries are a safety concern for young athletes. Now, the American Medical Association (AMA) has a new set of guidelines aimed at protecting players from the danger of concussions- serious injuries caused by a blow to the head.
“By raising awareness of the serious risks associated with concussions and ensuring that the appropriate guidelines are in place, we can reduce the number of young athletes who may return to the game too soon, which can put their health at further risk,” said AMA Board Member Jack Resneck Jr, MD, in a statement.
The policy recommends that young athletes who may have a concussion be taken off the field as soon as possible. Then, they are only to return to their sport with a doctor 's written approval. The policy also sets age-specific rules for health care professionals and athletic organizations in evaluating and caring for concussions.
According to the Center for Disease Control and Prevention (CDC), a concussion is a type of traumatic brain injury (外伤性脑损伤) caused by a bump, or jolt to the head or hit to the body that causes the head and brain to move rapidly back and forth. This type of movement can cause the brain to bounce around or twist inside the skull (颅骨). It can damage brain cells and create chemical changes in the brain.
The CDC says that between 1.6 million and 3.8 million traumatic brain injuries caused by sports and recreation-related activities occur in the U.S. every year. A study from the Center for Injury Research and Policy showed that as many as 40% of high school athletes return to playing before they should. The AMA' S new guidelines should help to bring those numbers down.

A.Avoid using the head. B.Leave the field forever.

The kakapo, a bird that lives in New Zealand, is not designed for survival. Weighing up to 4 kilograms, it is the world's fattest parrot. It mates (交配)only when the rimu tree is in fruit, which happens every few years. It developed gradually in the absence of land-based natural enemies, so instead of flying above the trees it walks like a duck across the dry forest floor. When it moves unsteadily across something that might kill it, it will stand still.
Such unusual characteristics turned it into fast food for human settlers, and for the cats and rats they brought with them. It seemed to have disappeared by the 1970s, until scientists came across two undiscovered populations in the country s south. These survivors were eventually moved to small enemy -free islands, where researchers have spent decades trying to get them to breed (繁殖).
The scientists' patience is finally rewarded. The rimu was in fruit this year, and more than 80 chicks hatched, making this the best breeding season, on record. Many have. survived into adolescence, increasing the number of adult kakapos by a third, to 200 birds.
Another danger to the kakapo is a lack of genetic diversity. This is one reason why fewer than half of kakapo eggs hatch. By arranging the genome (基因组) of every living bird, scientists can identify closely-related individuals and put them on different islands. Every bird is fitted with something to track its slightest movement. If a female mates with an “unsuitable” male, the process can be stopped.
All these efforts cost almost New Zealand $1 .3 million this breeding season. Yet the kakapo's future still looks unsafe. Earlier this year a severe disease tore through the population. And tiny as the number of kakapos is, space is running out on the two islands where most of them live. New enemy-free settlements must soon be found.
1.Which of the following is a danger for the survival of the kakapo?
A.It is the smallest bird in the world.
B.It lacks exercise and usually stands still.
C.It adapts slowly, in genetic development.
D.It can't respond actively when facing danger.
2.In what way was the scientists' patience rewarded?
A.Adequate food supply for kakapos was guaranteed.
B.New settlements for kakapos were eventually found.
C.Kakapos were becoming increasingly aggressive.
D.Kakapos' birth rate reached the highest level.
3.Why did the scientists put kakapos in different islands?
A.To stop closely-related kakapos mating.
B.To help kakapo families live together.
C.To maintain the production of rimu fruit.
D.To protect kakapos from natural enemies.
4.What does the author think of the efforts to protect the kakapo in New Zealand?
A.They are successful. B.They are inadequate.
C.They are doubtful. D.They are unsafe.
My school appeared on the news last week because we had made an important change in our local area. Our class had planted a large garden in what was once only a vacant lot. It was a lot of work but it was all worth it. I got blisters(水泡) from digging, and we all got insect bites, too.
I learned a lot about gardening and collaboration(合作), and then I learned about the media. Our teacher telephoned the TV station and informed them of what we had accomplished. She spoke with the producer. The producer checked with the directors, but they said there were plenty of stories similar to ours. They wanted to know what was special about our particular garden, since many schools plant them.
The teacher explained that, after going on the Internet to learn about the prairie(大草原), we had made a prairie garden. We had gone to a prairie and gotten seeds from the plants, and then we planted them. We did not water the garden, but we did weed it. We decided to let nature water it with rain, since that was how prairies grew in the past. We sent a picture of the garden to the news station. In the picture, the grass was so high that it stood taller than the fourth grade students.
As a result, the producer sent a reporter to our school. He interviewed the headmaster and asked him many questions about the garden. After that, they interviewed us, and we explained to them what we had learned through this project.
That night, we watched the news, and there we were. The news reporter told our story. It was only two minutes long, but it was us. We were famous. All that work, all those blisters, it was worth it. We knew that when we saw the garden every day, but now we knew that the whole city thought so, too.
1.What seemed to be the TV directors’ initial reaction to the garden?
A.They were excited. B.They were surprised.
C.They were worried. D.They were uninterested.
2.What is special about the garden?
A.Weeds were allowed to spread naturally.
B.The grass grew faster than common grass.
C.The seeds came from the plants of a prairie.
D.Underground water was used for the plants.
3.What does the underlined word “that” refer to in the last paragraph?
A.We got blisters on our hands. B.Our hard work was worthwhile.
C.The garden would be famous. D.The project would be finished.
4.How did the author feel about the project?
A.Annoyed. B.Curious. C.Proud. D.Regretful.
