Question

Mother wanted to be a good provider,a role she ________ since her marriage to Father.
A shoulders B shouldered C is shouldering D has been shouldering
为D,因为since要加完成时态.
可问题是如果选D的话该句子不就有两个动词（wanted,has been shouldring)了吗?选B不是可以刚好让shoulderd作分词吗?

Answer 1

这个句子成分有点复杂……
先来说后面这部分,a role和she之间省略了which,这个'she _______ since her marriage to Father'是用来界定a role的定语从句；而'a role……'是'a good provider'的同位语,因此,后面这部分应该是个同位语从句,应该有个动词的.所以说,前半部分是主句,需要有谓语动词；后半句是从句,既然是句子肯定要有动词,所以有两个动词就对了.
再解释一下同位语：同位语是用来进一步解释其所对应的东西的成分,比如We students must do our homework.中,students是we的同位语,进一步说明这个'we'指的是学生.汉语里有同样的用法,比如“他们北方人”之类的
