A.has come B.have been C.has been D.have come
可是后面是here 不应该用come么。

not only the parents but also their son ______ here for two yearsA.has come B.have been C.has been D.have come可是后面是here 不应该用come么。
补充：不能用come.因为come是瞬间动词,不能与后面的for two years 一段时间连用,has been here表示“到这里”,是正确答案.
答案：C
解释：not only … but also …连接两个名词作主语时,谓语动词的单复数形式要根据就近原则来确定.for two years 与现在完成时连用,所以正确答案是C.

C

C,
方法：先排除has。因为不是单数。

所以，在这里要用，have been
