She can play the piano just as wonderfully as you do.
Bob can run as fast as I do.
None of us can run as fast as he can.
句子最后一个词是can 还是do? 还是都可以?谢谢老师!
can和do都可以,意义略有不同。用can表示能力,用do表示我通常跑的速度。比较分句的操作词并非必须和主句一致。
还可以说,He can run as fast as I did. (我昨天跑百米用了12秒。)
He can run as fast as I do. (我通常跑百米用时12秒。)
He can run as fast as I can. (我可以12秒跑完百米。实际并不一定真的跑了,只是潜在的能力。)
