With global warming and melting ice, it isn’t easy being a polar bear anymore. 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 ice---the 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 completely 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(驯鹿) and snow geese---as 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 becomes second nature.

阅读下面短文,根据其内容写一篇60词左右的内容概要。
A woman gave up her fetus(胎儿) in Central China’s Hubei Province after her 13yearold daughter threatened to commit suicide.
The event drew people’s attention to the single child mentality,which may be an obstacle as the country tries to relax the singlechild policy.The woman,44,had been pregnant for 13 weeks.Her daughter became unhappy after knowing that she was going to have a brother or sister.Her anxiety reached its peak,when the ninthgrader cut her wrists with a razor blade in an attempted suicide,according to a report of the local Wuhan Evening News.
The case may sound extreme,but the girl is not the only child in China showing jealousy of a younger sibling.Zhuang Zhuang(not his real name) was 16 when his younger brother was born last year.Since then he’s fallen behind in his classes.
“They never cared about me again,” the teenager complained.“I’m under great pressure to do well in academic performances,so as to win attention from my parents.”
The onechild policy was relaxed in 2013,in an attempt to address the country’s declining labor force and aging population.A majority of the Chinese provincial regions,including the most populated Henan,have allowed couples to have a second child if either parent is an only child.Beijing also followed suit.Although 11 million couples have been granted a permit to have a second child,statistics from the National Health and Family Planning Commission show only close to one million couples out of them filed birth applications by the end of last year.“Economic cost”,“time cost” and “one child is enough” were listed as top reasons for not having a second child,according to a survey by China Youth Daily.Many parents give the third reason,out of concern for their first child.
Xia Xueluan,a sociology professor at Peking University,believes the onechild policy,enacted more than three decades ago,created many young “emperors” and “empresses” in China.“Parents spoiled their children,so many kids tend to be selfcentered without consideration for others,” he said.

【题目】概要写作
阅读下面短文,根据其内容写一篇60词左右的内容概要。
You may never think a documentary film could have aroused so much public enthusiasm in Chinese history.Nowadays everybody is talking about a new 7part documentary called A Bite of China which was recently broadcast late at night on CCTV1.The documentary describes various gourmet items across the vast Chinese culinary landscape.
According to Taobao,China’s biggest online retail website,just five days after the series began to air,nearly 6 million people went to the site in search of various local specialties,particularly those mentioned in the documentary.More than 7.2 million deals were concluded.A ham producer from Yunnan Province saw his sales grow 17fold in five days.
However,one can’t help but believe that the documentary’s popularity is probably linked to the endless stream of terrible food security issues that have emerged in recent years.In one wellreceived article,a netizen wrote,“I wonder how many felt so emptyhearted and sighed after watching the film.Bluevitriol watered chive,formaldehyde sprayed cabbage,Sudan Red colored salty eggs,restaurants using gutter oil.The list is long...”
How will a varied and ancient food culture that is famous worldwide and which should have made the Chinese proud end? Food is the most vital thing in people’s lives.Yet China’s food industry has made people a little worried due to some severe food safety crisis.The market is huge while the cost of faking and cheating is so low for immoral businessmen; and the punishment is too light.Take the milk industry as an example.Although Sanlu,the company that sold the melamineadulterated milk powder,was punished,thousands of other dairies didn’t wor hard to improve the quality.Therefore,food safety problems should be an important concern of Chinese government so that our ancient food culture can be preserved.
As the documentary shows,people are attracted not to gourmet items like matsutake,a species of rare mushroom grown naturally in remote forests,but to common Chinese dishes like barley,lotus root or tofu.They are what meet our basic needs.This explains why people are so excited about A Bite of China—it is a reminder that there is still a world out there where food is excellent and safe.

阅读下面短文,根据其内容写一篇60词左右的内容概要。
If you know something is bad for you,why can’t you just stop?About 70% of smokers say they would like to stop.Drug and alcohol abusers struggle to give up the bad habits that hurt their bodies and destroy families and friendships.And many of us have unhealthy weight that we could lose if only we would eat right and exercise more.So why don’t we do it?
Some scientists have been searching for answers.They’ve studied what happens in our brains as habits form.They’ve found answers to why bad habits,once formed,are so difficult to kick.And they’re developing ways to help us make the changes we’d like to make.
Habits are a normal part of life,and are often helpful.“We wake up every morning,shower,comb our hair or brush our teeth without being aware of it,” Volkow says.We can drive along familiar routes without really thinking about the directions.“When behaviors become automatic,it gives us an advantage,because the brain does not have to perform the action on purpose,” Volkow says.This frees up our brains to focus on different things.
One way to kick bad habits is to focus on your unhealthy habits.Then try your best to stop them.For example,habits can be linked in our minds to certain places and activities.You could develop a plan,to avoid walking down the hall where there’s a candy machine.Try to avoid going to places where you’ve usually smoked.Stay away from friends and situations linked to problem drinking or drug use.
Another helpful way is to replace unhealthy habits with new,healthy ones.“It doesn’t work for everyone,” Volkow says.“But certain groups of patients who have a history of taking drugs can do something else like running and it helps them stay away from drugs.”
