同义句 Do you know whose computer this is
Do you know whose computer this is?（改为同义句）
Do you know ______the computer_______
He looked so tired as if he had________all his strength?(use up)
这里是填used
第一个是每空一词的啊

Answer 1

1.Do you know whose computer this is?
=Do you know (whose) the computer (is)?
2.没错,就是用used up:
He looked so tired as if he had (used up) all his strength.
use...up是及物动词短语,必须要加宾语,意思是“用完/耗尽...”；
此as if引导的方式状语从句使用了虚拟语气,所以从句用了过去完成时,即谓语结构为“had + 动词过去分词”.
