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。
