标题: [讨论]再问大全408

1. In the last few years, the number of convicted criminals given community service sentences, which allow the criminals to remain unconfined while they perform specific jobs benefiting the public, have risen dramatically.

(A) sentences, which allow the criminals to remain unconfined while they perform specific jobs benefiting the public, have

(B) sentences, performing specific jobs that benefit the public while being allowed to remain unconfined, have

(D) sentences which allow them to remain unconfined in their performing of specific jobs beneficial to the public has（E）

(E) sentences allowing them to remain unconfined while performing specific jobs that benefit the public has

答案是E，其他都有错误。我想问：E中allowing的逻辑主语无疑是sentence，但是while performing 的逻辑主语是什么？似乎只能是criminals（them），因此while performing 似乎不能和allowing平行啊！！performing 按照意思只能和remain unconfined 平行，但是在一个不定式中（to do)可以再套用while从句吗？？迷惑

请教大家。。。

此外D选项中，假设which改为that，其他错误不看，has前面是否一定需要逗号？？

另外问一个知识点：介词+one's doing 这个表达是否肯定错？？以前上XDF，记得老师这么说过，还有one's being done是否也错？？？

1,"但是在一个不定式中（to do)可以再套用while从句吗？？" 应该是这样的。while 修饰 remain confined。

2，一般情况下，介词短语是可以找到主语的，能找到主语的介词短语，介词后面的动名词就已经有了逻辑主语，没必要在后接的动名词前加one's，多余。has前没有插入语，所以主助动词has前不能有逗号。one's being done 95%情况下是错的，看能不能找到逻辑主语。

其他都能理解。只是在to do里套while从句实在不能理解，而且动词上是to do和doing并列，不理解

to remain是宾语补语，也就是说them和to remain是主谓关系。allow (them to do while doing), 没有to do和doing的并列，while doing是to do的从属成分。

最好你查一下S（主）+V（谓）+O（宾）+C（补）的句子的语法概念。语法书上相应的章节看了之后就应该理解了。

好的，我去看语法书，语法知识都忘光了。谢谢tianwan兄指点
