Question

【題目】Not until he went through real hardship _____the love we have for our families is important.
A.had he realized
B.did he realize
C.he realized
D.he had realized

Answer 1

【答案】B
【解析】句意：直到他經(jīng)歷了真正的困難，他才意識(shí)到我們對(duì)家庭的愛(ài)是很重要的。not until放在句首的時(shí)候，后面的主句是部分倒裝；而且這句話的從句是過(guò)去時(shí)，主句的動(dòng)作發(fā)生在從句的動(dòng)作前面，不可能是過(guò)去完成時(shí)，用一般過(guò)去時(shí)。選B。
