3. 动词 + prep + it + that-从句See to it that you’re not late again. 注意千万不要再迟到。Look to it that this doesn’t happen again. 注意不要再发生这种事。I can’t answer for it that he will come. 我不能保证他会来。You may rely on it that he’ll come to meet you. 你放心，他会来接你的。能用于此结构的动词常见的有see to, look to, insist on, stick to, depend on, answer for 等。
