T learn the Present perfect tense with already and yet
I have already pened the dr?

Have yu had dinner yet?

现在完成时 Present perfect
定义：表示过去发生或已经完成的某一动作对现在造成的影响或结果。（动作发生在过去，对现在造成影响）
肯定句: 主语+have/has+过去分词+其他否定句: 主语+haven’t/hasn’t+过去分词 +其他一般 Have/Has+主语+过去分词+ 疑问句：…？肯定答语: Yes, 主语+have/has.否定答语: N, 主语+haven’t/hasn’t.
动词过去分词的变化形式大部分与动词过去式形式相同，但是不规则动词的变化形式没有规律，需要记忆，比如：
see-saw-seen; be-was, were-beeneat-ate-eaten; break-brke-brkeng-went-gne; take-tk-takensend-sent-sent; find-fund-fundmake-made-made; have-had-had
你规我也规，你不规，我也不规
already 已经，常用于肯定句中。一般置于助动词have/has之后，过去分词之前， yet，在现在完成时句型中常置于句末。 1) 已经，常用在疑问句中。 2) 还(没），尚未，常用于否定句。
现在完成时与already，yet 连用

同学们要注意现在完成时与一般过去时的区别。虽然这两个时态都和过去发生的事情有关，但是现在完成时强调这一动作与现在的关系，如对现在产生的结果、影响等，而一般过去时只表示过去的事实，不表示和现在的关系。如：
I went hme at 10:00 yesterday. I have gt hme nw.我昨天十点回家的。现在我已经到家了。I have already finished my hmewrk. I finished it an hur ag.我已经写完作业了，我是一个小时之前写完的。
