Answer 1

A

解析試題分析：考查固定句型：“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。這題容易誤選B，認(rèn)為這是強(qiáng)調(diào)句型。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 . 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。所以選A。
