基础英语口语：I have + (past participle)

Again, 'I have' shows possession or something acquired. By adding a past participle you are informing someone of a past or completed action done by you.

我们又看到了I have，这里也是表达拥有或者获得了什么。但是后边加一个过去分词，你就可以告诉别人你过去所完成的某个动作。

Here are some examples:

"I have done it."我已经完成了。

"I have heard that before."

"I have driven a car."我开过车。

"I have forgotten the words."

"I have read that book."

"I have eaten at that restaurant before."我在那个酒店吃过饭。

"I have flown in an airplane."我坐过飞机。

"I have forgiven you."我已经原谅你了。

"I have seen you before."我以前见过你。

"I have written a letter."
