I don't think she cares, does she? You don't think she cares, do you? He doesn't think he cares, does he?,3. “两副面孔” if 和 when 等既能引导宾语从句，又能引导状语从句。因此，碰到此种情况要认真分析。当从句表示将来时，若引导的是宾语从句，它们的时态常用一般将来时；若引导的是状语从句，它们的时态常用一般现在时代替将来时。 If it rains tomorrow, I wont come.（时间状语从句） I dont know if it will rain tomorrow. （宾语从句）,宾语从句用法 宾语从句需注意，几点事项应牢记。 一是关键引导词，不同句子词相异。 陈述句子用that；一般疑问是否（if, whether）替； 特殊问句更好办，引导还用疑问词。 二是时态常变化，主句不同从句异。主句若为现在时，从句时态应看意；主句若为过去时，从句时态向前移。 三是语序要记清，从句永保陈述序。,巧学妙记,Exercise Can you see_?
