理解【过去完成时】的谓语形式
13
The mouse has been out of the house
when the cat is blocking the mouth of the cave.
请根据谓语动词的公式（谓语动词 = 助动词+实意动词）和主谓一致，分析谓语动词的形式中起主要作用的因素是什么？
谓语
主语
has
done
单数
复数
have
done
现在完成时谓语形式：
has/have + done
The mice have been out of the house
when the cat is blocking the mouth of the cave.
主语由mouse变成mice，助动词“has” 变成“have”.由此可知:谓语动词的形式中起主要作用的是助动词。
助动词随着主语变化而变化。
实意动词不变。
The mouse has been out of the house
when the cat is blocking the mouth of the cave.
请根据谓语动词的公式（谓语动词 = 助动词+实意动词） ，把时间改为过去，分析谓语动词的形式的影响因素。
The mouse had been out of the house
when the cat was blocking the mouth of the cave last night.
现在完成时
谓语形式
has/have + done
过去完成时
谓语形式
had + done
时间从现在变成last night ，助动词has/have变成had，done不变。由此可知：时间改变，谓语动词的形式的影响因素还是助动词。
过去完成时谓语形式：
had + done
助动词随着时间变化而变化。
实意动词不变。
思考：过去完成时谓语动词的形式had done中的实意动词为什么要用过去分词done呢？
老鼠的动作先于猫的动作,主句的动作先于从句的动作。所以主句的实意动词都要用done。”
The mouse has been out of the house
when the cat is blocking the mouth of the cave.
The mouse had been out of the house
when the cat was blocking the mouth of the cave last night.
A
B
句2中，猫的动作是过去发生的，而老鼠的动作先于猫的动作，发生在过去的过去，所以要用过去完成时。
now
过去
过去的过去
16
过去完成时的谓语形式
谓语 动词 = 助动词 + 实意动词
过去 完成式的谓语 形式 = had(过去) + done(完成)
请用表格归纳过去完成时谓语动词的形式。
总 结 归 纳
记忆技巧：had是过去，done是完成，过去完成式,had加上done。
