Answer 1

分析 大多數美國家庭都小于其他國家的家庭．美國的孩子在他們長大后會離開他們的父母的回家，他們經常住得離父母遠，父母經常讓孩子們自己選擇工作，美國人認為它年輕人自己決定他們的生活是重要的．

解答 81．smaller考查形容詞的比較級．根據空格后的than可知應該用形容詞的比較級，結合句意：大多數美國家庭都小于其他國家的家庭，故填smaller．
82．parents'考查名詞的用法．根據下一句：因為他們想要找到好工作，他們通常生活遠離他們的父母，可知此處應該是：美國的孩子在他們長大后會離開他們的父母的回家，故填parents'父母的．
83．usually考查副詞的用法．結合句意：他們經常住得離父母遠，此處應該是usually，修飾動詞live．
84．themselves考查代詞的用法．根據上一句：父母經常讓孩子們自己選擇工作，可知此處應該是美國人認為它年輕人自己決定他們的生活是重要的．by oneself獨立做某事，oneself要和前面的young people 一致，故填themselves．
85．asked考查被動語態(tài)．結合句意：孩子們被要求在房子周圍做一些工作，主語和謂語動詞是被動的關系，應該用被動語態(tài)，被動語態(tài)的構成是be+過去分詞，故填asked．

點評 做這類題，不但要選擇正確意義的詞、詞組及句型，還要根據具體語法和語境，選擇適當的時態(tài)、語態(tài)及使用正確的詞形．
