非谓语动词答案的疑惑

9．Most of the artists ______ to the party were from South Africa.
A.invited B.to invite C.being invited D.had been invited
析：“被邀请参加晚会”，应选表被动意的选项，B不可用。D项少引导词who，也应排除。又因短暂动词的现在分词被动式不可作定语，C也应排除，只有A.invited(＝who were invited)才是正确答案。

为什么说D少引导词WHO？很奇怪。前面不是有主语了吗？为什么这里还要引导词？

又因短暂动词的现在分词被动式不可作定语
这句话是什么意思？正在被邀请不行吗？也说得通吧

Answer 1

第一个疑问：如果是第四个选项的话，had been done 不是非谓语动词的形式啊。
如果选用，应该是加上who作定语从句了
第二个疑问：短暂动词又叫点动词，是一瞬间就可以完成的动作，而现在分词被动式表示一种状态，是一个过程，与点动词的概念相悖。
附上现在分词的基本用法:
1) 一般主动式用法:
A.作定语:The sleeping child is only five years old.(=The child who is sleeping is…)/The girl writing a letter there can speak English very well.(=The girl who is writing a letter can…)
The factory making TV sets is very large.(=The factory which makes TV sets is very large.)
B.作表语:The story sounds very interesting./The news is very exciting.
C.作宾补:学用于see, watch, hear, feel, find, have, keep等动词之后.
例如:We can see steam rising from the wet clothes. /I saw Tom coming out of the house. /Don t keep the students doing homework all day.
注:上述动词后跟不定式作宾补表示动作的过程,而不是正在进行中的动作,而现在分词作宾补则表示正在进行中的动作.例如:I heard them singing in the room

Answer 2

D少引导词WHO，定语从句who had been invited to the party这句是修饰前面的artists。

你说是正在被邀请，但后面的were是过去式啊。。总之怪怪的。。呃。。真的不知道如何解释C了。。动词的过去分词作定语就表示了被动语态。。还选C干嘛？

Answer 3

首先，谁说前面有主语就不需要引导词，你也不看看这是什么从句，主语从句是必须有引导词的。
再次，不能是现在被邀请，因为后边有were。
