虚拟语气的错综复杂句,怎么判断?
答
if you had worked hard，you would get higher marks
如果没有明确的时间状语，可以根据语境而定。如这个句子，很明显是在说过去要是认真点，现在就不会分数低。从句与过去事实相反，谓语用had done；主句与现在事实相反谓语用would do。
答
如果从句和主句都表示过去的,那从句用had done,主句用would ,could,might,should+have done
如：If you had taken my advice,you would not have been late for the meeting yesterday.如果从句表示过去的,但主句表示现在的,从句用had done,主句用would ,could,might,should+do,如：If you had taken my advice,you would not be late for the meeting now.这种一般都有个时间,如果没有表示时间的词也可以从上下文看出.
