insist 在中学阶段，只要掌握以下三种用法即可：1、insist on/upon (sb/ones) (doing) sth如：You should insist on your dream.You should insist upon doing exercise every day.You should insist on her apologizing to you.2、insist + that 引导的宾语从句1）如果 insist 翻译为“坚持说/坚持认为” ，即 that 从句表示已经发生的动作时，则宾语从句使用陈述语气，即从句该用什么时态就用什么时态，当然还要和主句时态保持呼应。如：She insisted that she was right.She insisted (that) she had been to Beijing the year before.2）如果 insist 翻译为“坚持要求/坚持主张” ，即 that 从句的动作当时尚未发生的话，则宾语从句必须使用虚拟语气，即从句谓语动词由“should + 动词原形”构成，且 should 可以省略。如：He insisted that she (should) say sorry to him frist.
