Answer 1

分析 大多数美国家庭都小于其他国家的家庭．美国的孩子在他们长大后会离开他们的父母的回家，他们经常住得离父母远，父母经常让孩子们自己选择工作，美国人认为它年轻人自己决定他们的生活是重要的．

解答 81．smaller考查形容词的比较级．根据空格后的than可知应该用形容词的比较级，结合句意：大多数美国家庭都小于其他国家的家庭，故填smaller．
82．parents'考查名词的用法．根据下一句：因为他们想要找到好工作，他们通常生活远离他们的父母，可知此处应该是：美国的孩子在他们长大后会离开他们的父母的回家，故填parents'父母的．
83．usually考查副词的用法．结合句意：他们经常住得离父母远，此处应该是usually，修饰动词live．
84．themselves考查代词的用法．根据上一句：父母经常让孩子们自己选择工作，可知此处应该是美国人认为它年轻人自己决定他们的生活是重要的．by oneself独立做某事，oneself要和前面的young people 一致，故填themselves．
85．asked考查被动语态．结合句意：孩子们被要求在房子周围做一些工作，主语和谓语动词是被动的关系，应该用被动语态，被动语态的构成是be+过去分词，故填asked．

点评 做这类题，不但要选择正确意义的词、词组及句型，还要根据具体语法和语境，选择适当的时态、语态及使用正确的词形．
