Presentatin
现在完成时用在什么地方呢？
当我们要表达“某人曾经做过某事”, “某人已经做了某事”等意思时, 英语要用“现在完成时”来表达。
1.My parents have travelled t Dalian by ship. 我父母曾经坐船去大连旅游。
2.She has finished her hmewrk.她已经完成作业。
Lk at the sentences
3.My parents haven’t travelled t Dalian by ship. 我父母未曾坐船去过大连旅游。
4.She hasn’t finished her hmewrk. 她还没有完成作业。
5.Have yur parents travelled t Dalian by ship? 你父母曾经坐船去大连旅游过吗？
6.Has she finished her hmewrk?她已经完成作业了吗？
要表达“刚刚做完某事” “已经做完某事”时，我们同样可以用现在完成时。例如:I have just heard the news.Astrnauts have already been t the mn.可以看出，just 用来表示“刚刚”，already 用来表示“已经”，一般置于have/has之后，两者都用于肯定句，在否定句中则要用yet,表示“还（未）”。例如：The scientists haven’t heard frm it yet.
与现在完成时连用的几个副词：肯定句:疑问句和否定句: yet 常置于句末already, never, ever, just一般置于助动词have/has之后，过去分词之前。
already, just, ever, yet, never
already, just
ever, yet, never
