More than two thirds of the world’s polar bears will be wiped out by 2050, according to a shocking new study. By then, scientists say, global warming will have melted 42 percent of the Arctic sea ice. By 2100, only a very few of these important creatures will be left.

The report has been produced by the US Geological Survey. The scientists have publicized their findings in the hope of influencing US Interior Secretary Dirk Kempthorne, who has been asked to put polar bears on the US endangered species list.

Polar bears depend on floating sea ice as a platform for hunting seals, which are their main food. Without enough ice, polar bears would be forced to go onto the land, where they are poorly skilled hunters, and would be unlikely to adapt to the life on the land in time. Experts say few little bears would survive and the stress could make many females unable to get pregnant.

The team of American and Canadian scientists spent six months studying bears, on the ground, from spotter planes and in the lab，using computer models. Some team members fear the result is even worse for the bears than what their report says. They say the Arctic is warming faster than anywhere in the world and much faster than their computer had been forecasting. Satellite observations have showed that the ice has decreased to an all­time low.

However, not everyone in the scientific community believes that global warming is happening on such an alarming scale. Another investigation has found that polar bears are still being hunted by wealthy “sportsmen” who want their skins and heads. At least ten international companies offer bear­hunting trips.

1.What do we know about Dirk Kempthorne according to the passage?

A. He is an animal scientist.

B. He is a protector of animals working for the US government.

C. He was asked to put polar bears on the US endangered species list.

D. He offered to put polar bears on the endangered species list.

2.Why will polar bears die out if there is not enough sea ice?

A. Because polar bears can’t catch enough food without ice.

B. Because polar bears eat ice when they feel thirsty.

C. Because polar bears will be easily found by hunters without ice.

D. Because most female bears are used to giving birth under ice.

3.After a six­month study, some scientists fear that________.

A. there is something wrong with their computers

B. polar bears will disappear even faster than they ever expected

C. their computer models are not as accurate as they expected

D. global warming will destroy everything in the Arctic

According to the latest survey by the Asian Development Bank, Asian parents are spending billions of dollars on private tutors (家庭教师) for their children and the practice is growing despite doubts about its effectiveness.

“Shadow education” is an expanding business not only in wealthy countries, but also in some of the region’s poorer nations as parents try to give their children the best start in life, the study saiD. Nearly nine out of 10 South Korean elementary pupils receive private tutoring, while the figure for primary school children in India’s West Bengal state stands at six out of 10.

The study estimated that the costs of private tutoring in South Korea were equivalent (相等的) to 80 percent of government spending on public education. Japan spent $ 12 billion on extra teaching in 2011, while the figure for Singapore stood at US $ 680 million in 2009.

Extra academic work aims to help slow learners and support high achievers. Many Asian parents view it as a constructive way for adolescents (青少年) to spend their spare time. However, it can also reduce the students’ time for sports and other activities important for their overall development as well as cause social tensions as richer families are able to pay for better-quality tutoring, the study said.

The study calls for a review of educational systems to make such extra teaching less attractive.

1.Why is “Shadow education” an expanding business?

A. Because parents want to spend their money.

B. Because children don’t want to go to school.

2.According to the article, what is the purpose of extra academic work?

A. To aid slow learners and support high achievers.

About 45 percent of Americans don’t get enough sleep, according to a recent survey. However, the benefits of getting enough sleep far outweigh the thrill of watching TV for one more hour or surfing the web. Getting a better night’s sleep will help you lose or keep your weight more effectively. Try these simple steps to improve your quality of sleep.

Take time to relax

So many of us go-go-go until it’s time for bed, but it’s important to take time to slow down and relax before sleeping. Do relaxing things, such as listening to soothing (抚慰的) music or deep breathing. Avoid stimulating (刺激的) activities such as writing e-mails, talking on the phone and watching TV. Some guidelines (指导方针): no e-mail after 8 p.m. and no TV or phone calls after 9 p.m..

Darker is better

Your body regulates your sleep cycle in response to the presence and absence of light, so dim the lights as evening approaches. Try getting ready for bed by candlelight. When you’re ready to sleep, make sure your room is as dark as possible.

Put your thoughts to bed

We all need time to process our day, but bed is not the place to do it if you want to sleep well. Take 10 to 15 minutes to record your thoughts in a journal. This effective technique will capture what’s in your mind so you don’t lie awake. Tell yourself you’re putting your thoughts to bed so that you can go to bed.

No sugar or alcohol before bed

These may wake you up. If you need a snack before bed, make it protein.

Try to get more sleep

Get an extra hour or two of sleep every night for a week and see how you feel. You’ll notice the difference!

1.The purpose of writing this text is to ________________________.
