改句子的英语题
The gardener said that he( (cut)) that tree down yesterday.
I told you I ( (have)) never played tennis before.
What does he said that he ( (do)) last weekend?
When does he told you that he ( (buy)) this car?
1,是不是用if引导的句子中的动词都应该是动词原形?
2,我们经常可以看见用can或may代替一些词组.那么can能代替什么词组,may呢?
答
cut had did bought
1.不是if引导的句子都用动词原形,有3种情况,当从句一般现在时,主句将来时.从句过去时,主句过去时.还有就是在虚拟语气中用过去完成时或者过去时
2.can表能够的意思能代替be able to这个短语,may只是表可能的意思代替不了什么词组
