3、1. You shall borrow the book _ I have finished reading it. 12. _ the manager comes here for a visit next week, Ill talk with him about this. 1-12题 when when 从句的A事件，相当于另一个事件B发生的时间点。也就是说，when 从句的重点不在动作本身发生的状态，而只是把它作为一个时间点，所以when 多数情况下用的是一般过去时，则不用正在进行时。因为如果用正在进行时，它表示的就是一段时间而不是一个时间点了。根据这一点,我们可以理解：when 从
