答案：【解析】：这是一道英语阅读理解题目，主要考查学生对于文章内容的理解和逻辑推理能力。题目给出了一个关于考拉的短文，并要求从六个选项中选出五个可以填入空白处的最佳选项。
首先，我们需要仔细阅读短文，了解考拉的基本特征和生活习性。然后，根据每个空白处的上下文，从给出的选项中选择最合适的句子填入。
(1) 根据上文“Koalas have short front legs and long strong back legs. Their fur is brown and thick.”描述考拉的外貌特征，此处应选择描述考拉其他外貌特征或与之相关的句子。选项D“Koalas live in trees and have big noses to smell.”符合这一要求，描述了考拉的生活环境和其他特征。但考虑到此空后文提到“A baby koala is very small when it is born.”，更侧重于考拉幼崽的特征，因此此处应选与考拉整体特征相关的句子，选项B“It keeps them warm during the cold weather.”描述了考拉皮毛的作用，与上文紧密相关，是更合适的选择。同时，D选项可以放在后面描述考拉生活习性时填入。
(2) 此处描述考拉幼崽刚出生时的状态，根据下文“It lives in its mother’s pouch(育儿袋) for 5 to 7 months.”可知，应选择描述考拉幼崽出生时状态或特征的句子。选项C“It has no fur and can’t see anything either.”符合这一要求。
(3) 此处描述考拉离开母亲育儿袋后的成长情况，应选择描述考拉成长后特征或习性的句子。选项E“As adults, koalas grow to be about 60 cm tall and weigh from 9 kg to 13 kg.”符合这一要求。
(4) 此处描述考拉的历史情况，特别是数量变化。根据下文“During the 1920s, however, people kept killing them for their fur and lots of koalas died.”可知，应选择描述考拉过去数量或历史遭遇的句子。选项A“Once there were millions of koalas in Australia.”符合这一要求。
(5) 此处描述考拉当前面临的生存威胁，应选择描述考拉生存困境或威胁的句子。选项F“They have fewer and fewer places to live and many of them die from diseases.”符合这一要求。
