試題分析：這篇短文主要介紹了美國黑熊的生活習(xí)性等基礎(chǔ)信息。

【1】A根據(jù)前文In the eastern part of their range, most of these bears have shiny black fur, but in the west they grow brown, red, or even yellow coats。在東部，大部分黑熊長有富有光澤的黑毛,但在西部它們長著棕色,紅色,甚至是黃色的毛。主要談?wù)摰氖遣煌�方位，黑熊的毛色不同。A符合這一點(diǎn)，故選A。

【2】G第二段Black bears are the smallest of all American bears, ranging in length from five to six feet, weighing from three hundred to five hundred pounds. 黑熊是美國熊類中最小的熊，身長5到6英尺，重三百到五百磅。主要講得是黑熊小的特點(diǎn)。G符合，故選G。

【3】D根據(jù)后文However, if attacked, most can climb trees and cover ground at great speeds. 然而,如果它們受到攻擊,大多數(shù)黑熊能以極快的速度爬上樹。根據(jù)這個轉(zhuǎn)折關(guān)系，所以前面應(yīng)該說黑熊攻擊性不強(qiáng)，不危險(xiǎn)。D符合，故選D.

【4】C根據(jù)后文Unlike squirrels, woodchucks, and many other woodland animals, bears do not actually hibernate. 與松鼠、旱獺和其它的林地動物不同，熊并不真正地冬眠。因此前文應(yīng)該引出熊冬眠的習(xí)性。C符合。

【5】F根據(jù)后文They prefer to live in caves.它們更喜歡生活在洞穴里。可知前面應(yīng)該引出它們居住方面的習(xí)性。F符合。
