Mr Li _______ _______ _______ the Party for twenty years.

五、运用不同引语进行转换

分析：答案为on for。 has been提示时态是现在完成时态，“for+时间段”表示“持续(一段时间)”，常用在含有现在完成时态的句子里。

1. The manager left two hours ago.

  The manager _______ _______ _______ for two hours.

分析：答案为 has been away。leave为非延续性动词，不能与for two hours 这样的一段时间连用，而改成 be away这样的延续性动词后，则连用一般时间。
