mandative subjunctive,也就是意志類動詞(名詞、形容詞)的用法,文法假設語氣篇會詳細介紹。另外,若insist做"堅信"(=firmly believe)時,就不適用這種接原形動詞的用法了。雖然大考不再刁鑽文法,不過還是來個類似句型的小補帖:It is+形容詞:odd/strange/surprising/wonderful或名詞:a pity/no wonder/a shame/a surprise+that S +(should)+ 1. 原形動詞,或2. have + P.P. <表過去>;這是用來表達主觀情緒的句型,should做「居然」之意。例句:I am surprised that such an industrious student as John (should) play truant.像約翰這麼用功的學生居然會蹺課,真令我驚訝。
