(Answer)
✔The porter insisted on helping us with our baggage.
insist on +v-ing
insist on 後接帶 "-ing" 的動詞。
✔She insisted on me carrying her enormous suitcase.
insist on (someone('s) doing) something
insist on 除了後接 something 之外還可後接 someone doing something 或 someone's doing something
✔We insisted that he write the letter.
In the that-clause that follows such verbs as insist, decide, suggest, intend, suppose, etc., the predicate should be '(should)+infinitive WITHOUT to'.
在某些動詞,諸如 insist, decide, suggest, intend, suppose 等之後所接的 "that-從句" 中,其動詞部分應用 (should) 加原形動詞。注意:should 可省略。
