尖

I have walked 2 kilometers already. = 我已经走了2公里了。

Present perfect tense用于表达过去开始的某件事到现在还在进行或者还未完成。

同时也用作于事件已发生但是没有表明时间的时态。

尖

I have worked here since 1999. = 我自从1999年开始就在这里工作了。

在\'present perfect tense\'下表达正义时:\'
Subject + have/has + 动词的\'past particle\'.
\'work\'的past particle是\'worked\'。

She has met me once. = 她见过我一次。

这里\'meet\'的\'past participle\'是\'met\'。 大部分动词的\'past participle\'和\'past tense\' 是一样的，但是 \'irregular verbs\'就不同了。
