It takes about 10 minutes to walk and 5 minutes by bus.

题目

It takes about 10 minutes to walk and 5 minutes by bus.
这里用的固定短语是It takes sb some time to do stn.
是不是应该在by bus.前加 to

答案

It takes about 10 minutes to walk and 5 minutes by bus.
这句话没错.固定短语是It takes sb some time to do stn.也没错.
但是,by bus.前不能加 to ,因为by bus不是动词.
