Polar bears were added to the list of threatened species and will receive

special protection under U．S. law. Experts noted that the decline of Arctic

sea ice is the greatest threat to the bears.

Polar bears live in the Arctic and hunt seals and other fatty marine

mammals from sea ice. They also travel, mate, and sometimes give birth on the ice. But sea ice is melting as the planet warms, and it is predicted to continue to do so for several more decades.

Although many scientists say that human activity is directly responsible for the melting sea ice, the new polar bear protections will not change U．S. climate policy.

The U．S. classifies the polar bear as a marine mammal, which means that the bear's new threatened status will not stop oil exploration within its habitat.

Hunting of polar bears as a food source by certain native people and trade in native handicrafts made from polar bears will also continue. However, importing polar bear products from Canada will be banned. Scott Bergen is a landscape ecologist with the New York-based Wildlife Conservation Society and a contributing author to U．S. Geological Survey studies released in 2007 that found two-thirds of the world's polar bears could go extinct by 2050. He and other WCS staffs are “almost elated (使兴奋)”with the decision, he said.

“Even though it doesn't directly influence carbon emissions (排放) so to speak, we think it is a definite decision in the right direction and we're pleased to see the Fish and Wildlife Service is supporting the best science on this species，”he added.

Bergen noted that saving the polar bear will depend on international cooperation. Permanent sea ice habitat is likely to remain in areas outside of the U．S., particularly in Canada and Greenland.

Scientists view these areas as refuges that could allow some polar bear populations to survive over the long term and repopulate the Arctic if temperatures decrease and sea ice returns.

“If you take a long-term view — meaning a hundred-year view into the future，”he said，“polar bears' existence is not necessarily totally dependent on what happens in the United Stat 1．Experts think the greatest threat to the bears is that ________.

You often find somebody who works around you complaining all the time, don't you?

__4__About 70% of Americans say being around nonstop complainers sometimes has a bad influence on them. Luckily, here are 4 tips to help form positive patterns.

1．Self-awareness

When a negative thought pops into your mind, immediately correct it. Instead of telling yourself “That's a nice shirt, but I can't afford it，”you can change t he message to“That will look great with my black pants when I can afford it.” __5__

Of course, everyone complains sometimes. But the less frequently you complain, the better you will feel.

2．Distance yourself

__6__Excuse yourself and go somewhere quiet, somewhere outdoors in the fresh air. Think of something pleasant before returning. You have to take this seriously because negative people can and will pull you into the trouble.

3．Don't try to change complainers

If you find yourself trapped in a group of complainers in a meeting or at a social event, simply choose silence. Let their words bounce off you while you think of something else. Attempting to stop the complaining can make you a target._7__If someone says, “I hate Mondays, and weekends are too short，”try to think, “I'm glad I rested up over the weekend, so I'm ready to make some improvements on that big project.”

When someone is shouting at you angrily, throw the responsibility back at him by asking, “So what do you intend to do about it？”In most cases, complainers don't really want a solution. They just want to speak it out. If you make them aware that they themselves have to find the solutions,

they will leave you alone and find someone else to complain to. If so, you will be happy.
