Some studies have predicted that polar bears could die out by the end of the century. The good news is not all researchers think the bears are absolutely disappearing. Scientists at the American Museum of Natural History(AMNH) have published a new paper indicating that things might not be as bad for polar bears as some scientists expect. To understand the reason for the researchers’ cautious optimism, we must first understand the factors that are threatening the polar bear’s existence. Polar bears consume a diet of mainly young seals. In order to hunt these seals, polar bears need to rest at the top of sea icethe same ice that is increasingly melting for most of the year thanks to climate change. In another 50 years, experts expect that the Arctic will be too warm for sea ice to form for half of the year, leaving polar bears without a reliable food source and in serious danger of starvation. As it turns out, alternative food sources for the polar bears aren’t pletely out of the question. For as long as biologists have tailed after the animals, they’ve seen polar bears eating animals found on land like caribou(馴鹿) and snow geeseas well as the snow geese’s eggs. Can polar bears actually survive off these alternative food sources for long periods of time? To figure this out, researchers calculated the nutrients that a caribou and snow geese diet would provide. They found that even adult male polar bears would be able to obtain more calories than they would burn in hunting these meals. Moreover, the food would provide the food necessary to avoid starvation during the summer months. Unfortunately, not all polar bears have tended to seek food on land. That said, the researchers expect that necessity would push more polar bears to hunt on land to avoid starvation. They also expect that the bears could learn from their fellow bears how to hunt on land until the practice bees second nature. 【參考范文】With global warming and melting ice, some scientists think that polar bears could die out by the end of the century. However, other scientists disagree. They have found polar bears have found alternative food sources and they can survive by hunting animals on land instead of seals. Besides, the researchers expect more polar bears learn how to hunt on land to avoid starvation. 聽力原文：Text 1W: Did you have any working experience during college?M: Yes, I did some parttime jobs such as tourist guide and salesman.
