英语达人请进（请解释这个句子中的重要语法点）
Therefore they would have been more likely, had they not switched courses,
to cease attending lectures than those who did not switch.
Therefore they would have been more likely, had they not switched courses,
to cease attending lectures than those who did not switch.
这样翻译比较容易理解语法结构：
因此,如果没有转换过课程,(相对于那些没有转换课程的同学而言)他们更加可能中断参加课程.
所以主句是They would have been more likely to cease attending lectures.这是一个由情态动词Would引导的虚拟语气,其中又嵌套了现在完成时态have been.主句中重点的词组为 be likely to do sth.
had they not switched courses 在这里是条件状语从句,用于加强对主句行为的描述.这个从句本身是过去完成时态,同时将had前置强调虚拟语气（因为“他们没有转换课程”这一行为在过去已经发生过了）
