Spirit Bear习性录音原文：

　　Keeping these banks intact is important because these streams are home to salmon, which are the bears'main food source. In return, the bears'feeding habits nurture the forest. As the bears eat the salmon, they discard the skin and bones in great amounts on the forest floor, which provide vital nutrients.

　　注：灵熊的主要食物来源为溪流中的鲑鱼，他们吃鱼的时候，会把大量的鱼皮与骨头丢弃在森林地面上。

　　Spirit Bear受到的威胁录音原文：

　　The greatest threat to the bear's existence is the loss of its habitat. (…examples略) To make matters worse, the number of salmon in those streams is declining because there is no legal limit on fishing at the moment.

　　注：三点原因威胁了灵熊的生存：1.栖息地的丧失（原文例子中包括了伐木公司的砍伐与建造公路，本文略）2.鲑鱼数量的减少（由于当时对捕鱼没有法律限制）。3.繁殖能力低。

　　对应听力题目：

　　36. Habitat is being lost due to deforestation and construction of _________ by logging companies. (roads)

　　37. Unrestricted __________ is affecting the salmon supply. (fishing)

　　38.The bears'existence is also threatened by their low rate of ____________. (reproduction)

　　Spirit Bear 保护措施录音原文：

　　The government is now requiring logging companies to adopt a better logging method, which is a positive step. Other steps also need to be taken. (…略)

　　注：政府的两点保护方法：1.要求伐木公司采取更好的伐木手段。2.栖息地的扩张（本文略）

　　对应听力原文：

　　39. Logging companies must improve their _________ of logging. (method)

　　另外，ESSENTIAL GUIDE TEST1 SECTION4中的CAMEL中提到的其利用价值与剑桥真题3 TEST3 SECTION4 OSTRICH（鸵鸟）比较接近，都说到了他们的MEAT（肉）的使用方法，鸵鸟场景还对比了澳洲另外两种特色动物kangaroo（袋鼠）与crocodile (鳄鱼)的肉食用感受，同时考察了鸵鸟羽毛（feathers）与hide (皮)的用途。（题目如下）

　　OSTRICH 听力录音原文：

　　MEAT: ...kangaroo... looks and tastes rather like rabbit, though it's slightly darker in colour, but it's rather tough…

　　...ostrich, which most people say has a similar taste and texture to beef...

　　听力录音原文：

　　...their feathers...they were made into ladies'fans...

　　...for their hide. This can be treated to produce about half a square metre of leather...

　　从上可以看出，掌握部分背景知识其实可以侧面帮助我们消化一些本身无法理解的内容，或者是提前对某些题目做出适当的预测。本文仅仅从灵熊这篇文章入手，而有关动物场景仍然可以找出更多的共同处，希望考生们也可以多关注背景知识，从而做到遇到SECTION 4难度大的场景不慌不忙。
