第三单元
一 过去完成时态
1．我们用一般过去时态来谈论一个过去的动作。当我们想要谈论比过去更早的时间里发生的事情时，就用过去完成时态。
如：Upon entering the tomb, Carter’s lucky pet bird, which had led him to the place, was eaten by a snake.
2．在直接引语中，我们用过去完成时态来指代说话的时候就已经发生的动作。直接引语中的一般过去时态和现在完成时态在间接引语中改为过去完成时态。
如：“We emptied the tomb of everything it contained,” said Carter.-------
Carter said that they had emptied the tomb of everything it contained.
3．过去完成时态只是指在另一个过去的动作之前发生的动作，并不是指发生在一长段时间以前的动作。
如：I had done my homework this morning before I went to the museum.
4．过去完成时态经常跟以下引导的时间短语连用，如when, after, before, as soon as, until, since, by, for, already.
如：Then a few months after Carter had opened the tomb, Lord Carnarvon fell ill with a fever and died.
5．过去完成时态的构成：had+v-ed
如：Howard Carter had received money from Lord Carnarvon before he made his most amazing discovery.
二 现在完成时态还是过去完成时态
当我们谈论一个与现在有关的过去的事情时，我们用现在完成时态。
如：Howard Carter is one of the most famous explorers the world has ever known.
当我们在谈论过去，并要说明一个更早发生的动作的时候，我们就要用过去完成时态。 如：Not long after the tomb had been opened, people in Carter’s team began to fall ill and die strangly.
