　　The koala is found in coastal regions of eastern and southern Australia, from near Adelaide to the southern part of Cape York Peninsula. Populations also extend for considerable distances inland in regions with enough moisture to support suitable woodlands. The koala is not found in Tasmania or Western Australia.

　　通过此段，考生可以大致了解考拉的分布主要在澳洲东部及南部沿海地区，从阿德莱德到约克角半岛南部。而在塔斯马尼亚及西澳地区则没有发现考拉。

　　A baby koala is referred to as a joey and is hairless, blind, and earless. At birth the joey, only a quarter of an inch long, crawls into the downward-facing pouch on the mothers belly and attaches itself to one of the two teats.

　　这一段主要介绍考拉宝宝的主要情况，出生时候只有四分之一英寸长，生活在妈妈的育儿袋里。

　　The koala lives almost entirely on eucalypt leaves. This is likely to be an evolutionary adaptation that takes advantage of an otherwise unfilled ecological niche, since eucalypt leaves are low in protein, high in indigestible substances, and contain phenolic and terpene compounds that are toxic to most species. Like wombats and sloths, the koala has a very low metabolic rate for a mammal and rests motionless for about 16 to 18 hours a day, sleeping most of that time. 本段讲到考拉的饮食几乎完全依赖桉树叶生存，并且考拉的新陈代谢非常慢，一天可以16-18个小时不动。

　　建议考生在搜索的时候选用英文，在平时学习背景知识的时候，不断扩大对于相关这一主题的词汇量。这样在考试当中遇见相关背景的文章的时候不至于出现因生词过多造成理解误差的情况，同时也可以在考试当中节省阅读时间，保证阅读速度。
