Under no circumstances______without looking carefully to the rear.


A.should one back up a motor vehicle
B.a motor vehicle should back up
C.one should back up a motor vehicle
D.should back up a motor vehicle

答案:A
解析:
本题考察倒装,题目意为“在任何情况下都不应该在没有仔细观察后方的情况下倒车。”under no circumstances,其意思是:无论如何(都不要),绝不。由于under no circumstances表示否定并被放在句首,因此整个句子也采用了倒装结构,助动词should被提前(放到主语one的前面)。这种结构可以传递出醒目、强烈的否定信息,当需要警示他人时,使用under no circumstances的倒装结构会非常有效。
