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 has 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.

What about a terrorist attack? Put your mind at ease in nearly any situation.You can almost guarantee your survival if you never leave the house without 3 necessary items，i.e.a lighter (打火机)，LifeStraw(生命吸管) and a raincoat. Right off the bat，your first instinct (本能) might be to search for help the minute you realize you're in trouble.But survival experts insist you should stay where you are until help finds you；doing so will make it easier for the search and rescue team to pinpoint your location. What should you do until then，you ask? Prepare to hunker down (蹲下) for the long run.That's where your three pieces of survival gear come into play，Stewart says. For one，you should have something to start a fire.Fire­starting tools are inexpensive to purchase，and you can easily carry them around in a backpack or pocket.But even without a fancy item，all you really need is something to light the first flame. “You can use cotton balls covered in petroleum jelly(凡士林) as a fire starter，” Stewart said.“They are water resistant and will start a fire with just a spark.” Second，you'll need something to make water fit to drink，such as a canteen(水壶) that can boil water.Stewart recommends buying the LifeStraw，which can be put into the muddiest pool of water you can find and help you get clean water.It could still save your life，Stewart says. Paragraph 1： “I always say that your life depends on your water source，” he said.______________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ Paragraph 2： You can keep the three items with you when you are away from your home.________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ Paragraph 1： “I always say that your life depends on your water source，” he said.“If you are in a bad situation and have to drink water，you take the risk of drinking unclean water，which can quickly kill you.”In this case，the LifeStraw will come into play.Finally，Stewart recommends having a raincoat，or anything that can be used to protect you against the weather.Even food should take a back seat to these three necessary items，he says.“Everyone gets really worried about food，but the human body is designed to last a long time without food.When it comes to survival necessary priorities，food is on the bottom of the list，” he said. Paragraph 2： You can keep the three items with you when you are away from your home.You can keep them in a backpack if you're hiking or camping，or even in a car if you're traveling on the road.But in a word，the best thing you can do to ensure your own survival happens before you even leave.Tell people where you are going and when you will be back. 学科网（北京）股份有限公司 $$
