问题描述：
Most ot the professors ____ to the conference were from Beijing University.
A.invited B.to invite C.being invited D.had been invited
这一题标答是选A,
答
被动语态做状语 修饰professors ， professors 是被邀请来的 were表示了时态是一般过去时态
答
可以把invited当作是形容词，参考LS和看这个
(most of the professors) (invited to the conferences) (were) (from ...)
答
A啊这句话的意思是：大部分被邀请到会议的教授们都是来自北京大学的.是被邀请啊 所以要用被动语态,B就被排掉了.但这句话已经有 一个谓语了 were了,而一句话只能有一个谓语,所以所填处就不能有谓语了D(had)就被排除了...
答
Most of the professors were from Beijing University是主句,invited to the conference是动词过去分词做后置定语,教授是被邀请来参加会议的,所以invite与professor是被动关系,用过去分词,而不是现在分词
