句型说明
在英语中，“insist that sb (should) do sth” 是一个常见的表达方式，用于表示“坚持要求某人做某事”。
其中，should 可以省略，这是英语虚拟语气的一种典型用法。
结构如下：
insist that + 主语 + (should) + 动词原形
经典例句
- She insisted that he (should) apologize to his teacher.
- They insisted that we (should) leave immediately.
- He insisted that the meeting (should) be postponed.
- The doctor insisted that the patient (should) rest for a week.
- I insisted that she (should) take the job offer.
注意事项
- 当 insist 表示“坚持要求”时，从句使用虚拟语气（即动词用原形，美式英语中常带 should，英式英语中常省略）。
- 如果 insist 表示“坚持认为（某事属实）”，则不用虚拟语气，而用陈述语气。例如：
He insisted that he was innocent.
