1．actively 分析句子结构可知，空处修饰谓语动词，故要用副词形式actively。 2．the 此处的“study”就是上文提到的那个“A recent study”，故用定冠词the表示特指。 3．on 根据固定搭配spend sth. on sth.可知，此处填介词on。
4．doing 根据语境可知，这里说的是“停止做某事”，而不是“停下来去做某事”，故用stop doing sth.搭配。
5．who/that 分析句子结构可知，空处在句中引导定语从句，先行词为kids，关系代
词在从句中作主语，因此本空填who/that。
6．to succeed 此处是be likely to do sth.句型，故填不定式。
7．is said 本句含有“be said＋动词不定式”结构，且这里说的是现在的一般情况，主语为Personal happiness，因此填is said。
8．helpful 本空应填形容词helpful，与kind并列作表语。
9．dealt/should deal It’s time (that) ...句型中，that从句要用虚拟语气，即从句谓语用一般过去时或should＋do，其中should不可以省略。
