Question

【題目】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】

考查倒裝。句意：那對(duì)老夫妻已經(jīng)結(jié)婚40年了，從來都沒有爭(zhēng)吵過。never放在后句的句首，要用部分倒裝，for 40 years表明應(yīng)該用現(xiàn)在完成時(shí)，故B項(xiàng)正確。
