Question

It’s more than half a century _________ my grandfather joined the Party and became a servant to the people.

A．when

B．that

C．since

D．while

Answer 1

C

假若選B，將此句分析為強(qiáng)調(diào)句，那么若將此句還原為非強(qiáng)調(diào)句就應(yīng)該是My grandfather joined the Party and became a servant to the people more than half a century. 很顯然, 句中的 more than half a century 是一段時(shí)間，然而它修飾的謂語(yǔ)動(dòng)詞 joined…became 卻是兩個(gè)終止性動(dòng)詞，這顯然不合適。其實(shí)，此題應(yīng)選C，屬于“It is＋一段時(shí)間＋since 從句”句型，句意為“我爺爺加入黨組織成為人民的公仆已有半個(gè)多世紀(jì)了”。此句的主句謂語(yǔ)也可以用現(xiàn)在完成時(shí)態(tài)(has been)，但在口語(yǔ)中多用一般現(xiàn)在時(shí)代替。
