Question

【题目】The old couple have been married for 40 years and never once ___________ with each other.

A. they have quarreled B. have they quarreled

C. they had quarreled D. had they quarreled

Answer 1

【答案】B

【解析】

考查倒装。句意：那对老夫妻已经结婚40年了，从来都没有争吵过。never放在后句的句首，要用部分倒装，for 40 years表明应该用现在完成时，故B项正确。
