He______his watch everywhere but he couldn't_____it.

问题描述:

He______his watch everywhere but he couldn't_____it.
A.look for,find
B.found,looked for
C.looked for,find
D.found,look for


求选择理由

选C
因为look for寻找(表示一个过程)
find 找到(表示一个结果)
他到处找他的手表但是还是找不到.
根据意思应该在A和C两个选项中挑正确的.
A错在look,它得用过去式,因为后面那句he couldn't.could是can的过去式.
