--- Mary, will you go to Tom's birthday party this Friday evening?--- Maybe not, because I _____ so far.

A. have invited

B. will be invited

C. haven't been invited

D. wasn't invited

题目解答

答案

C. haven't been invited

解析

本题考查现在完成时的被动语态的用法。解题关键在于：

  1. 时间状语"so far"（到目前为止）通常与现在完成时连用；
  2. 被动语态的构成（be + 过去分词）；
  3. 否定句的表达方式。

选项分析

  • A. have invited：主动语态，与题意矛盾（Mary是被邀请者）；
  • B. will be invited：表示将来被动，但"so far"强调动作持续到说话时，需用现在完成时；
  • D. wasn't invited：一般过去时，无法体现"到目前为止"的持续性；
  • C. haven't been invited：现在完成时的被动否定形式，符合题意。

语法结构

现在完成时的被动语态结构为：
have/has + been + 过去分词
本句为主语为"I"，否定形式为：
I haven't been invited
