选择题
----- Oh, my goodness! My laptop must have got stolen.
----- But where _____ a thief have entered the house with all the doors and windows still locked?
A.should
B.could
C.dare
D.did
答案
答案:B
考察情态动词。should 应该;could 能够;dare动词,敢,常和to搭配; did,一般过去时态,助动词。句意:哦,我的天哪!我的笔记本电脑一定是被偷了。——但是在所有的门窗都仍锁着的前提下,贼怎么能够进入房子?故选B。
