1. Polar bears suffer from various health problems due to the build-up of fat under their skin. (FALSE)
文： one reason for this is that they have up to 11 centimeters of fat underneath their skin. Humans with comparative levels of adipose tissue（脂肪组织）would be considered obese and would be likely to suffer from diabetes and heart disease. Yet the polar bear experiences no such consequences.
2. The study done by Liu and his colleagues compared different groups of polar bears.(FALSE)
文： A 2014 study by Shi Ping Liu and colleagues sheds light on this mystery. They compared the genetic structure of polar bears with that of their closest relatives from a warmer climate, the brown bears.
3. Liu and his colleagues were the first researchers to compare polar bears and brown bears genetically. NG
文：A 2014 study by Shi Ping Liu and colleagues sheds light on this mystery. They compared the genetic structure of polar bears with that of their closest relatives from a warmer climate, the brown bears.
4. Polar bears are able to control their levels of ‘bad’ cholesterol by genetic means. TRUE
文：Liu and his colleagues found the polar bears had a gene known as APoB, which reduces levels of low-density lipoproteins -- a form of ‘bad’ cholesterol.
5. female polar bears are able to survive for about six months without food. TRUE
文： This process results in about six month of fasting, where the female bears have to keep themselves and their cubs alive, depleting their own calcium and calorie reserves.
6. It was found that the bones of female polar bears were very weak when they came out of their dens in spring. FALSE
文： in addition, six months later, when they finally emerged from the den with their cubs, there was no evidence of significant loss of bone density.
7. The polar bears mechanism for increasing bone density could also be used by people one day
文： if the mechanism of bone remodeling in polar bears can be understood, many bedridden humans, and even astronauts, could potentially benefit.
8. 很多人认为熊类是不聪明的也是_____的，
定位词： unintelligent
定位处：第5段第4行， Bears, on the other hand, seem to be perceived as stupid and in
many cases violent.
stupid 对应 unintelligent 后面的并列结构词 and， and后面的形容词为violent，所以答案应该为violent
9/10. In Tennoji Zoo, 熊会用树枝当做_____, 这让他能够击倒一些_____
定位词： Tennoji Zoo
定位处：第5段第6行，A male bear called GoGo in Tennoji Zoo, Osaka, has even been observed making use of a tool to manipulate his environment. The bear used a tree branch on multiple occasions to dislodge a piece of meat hung out of his reach. Osaka这个动物园中一只叫’狗狗’的小男熊 ，会使用工具来控制环境， 这只熊会用一个树枝去挪动那些本来够不到的肉。
So， using a branch as a 应该是用branch 当做一种工具，因此为tool， 去knock down 一些肉 meat
11. 一个wild polar bear 野生的北极熊找到了一个方法，这个方法能让他接触到_____所在的一个平台上。
定位词： platform, wild polar bear , 我们要找的就是平台上有什么，platform 上面有什么
定位处： 第5段，倒数第3行 … witnessed in wild polar bears, although not as obviously as with GoGo. A calculated move by a male bear involved running and jumping onto barrels in an attempt to get to a photographer standing on a platform four metres high. 在这一句中我们主要看platform旁边，platform上面有什么呢，我们可以看到 a photographer standing on a platform, 因此这一空填photographer-摄影师；照相师
12 北极熊也会有一些如有意识的控制物体或者和______很相似的活动。
定位词： conscious manipulation, and similar to
定位处： 我们在第6段开头句看到了manipulation这个词，对应着这个题目中的 conscious manipulation，后面又出现了objects，接下来我们就需要在objects后面找并列结构，以及和…相似的信息， …objects in piles and then knocking them over in what appeared to be a game. objects 后面很快出现了并列结构的and，继续向后面我们看到了appear to这个词组，appear to 表示“似乎，好像”, 也就是similar to的同意替换，因此这一空我们就填，appear to 后面的game，似乎是一个游戏，像游戏一样的活动
13. 熊们也会做出一些动作去表达_____如果他们在打猎过程中感到失望
定位词： movements, hunting, disappointed - 本段开始说emotion了，emotion也可以是一个定位词
定位处：第7段开头就出现了emotion， As for emotions, while the evidence is once again anecdotal, many bears have been seen to hit out at ice and snow - seemingly out of frustration - when they have missed out on a kill. 很多熊会敲打冰和雪，看起来非常的挫折，当他们没有捕杀成功时， 此处的kill对应hunting，打猎，捕杀， disappointed对应 miss out， movement就是指hit out at ice and snow 这一空中，我们要填写的是这些movement表达了什么，应该写frustration， 表达了沮丧，受挫
