我們之前學習了一些現在完成時的基本用法，今天我們就來繼續探討一下現在完成時的特殊用法：現在完成時還可用來表示過去發生的動作一直延續到現在，常帶有for或since 等表示一段時間的狀語。
如：
Mr Wang has lived here since 1983.
自1983年以來，王先生一直住在這裡。
I haven’t seen much of him recently (lately).
我最近沒見過他。
We have seen that film before.
我們以前看過那部電影。
Have they found the missing child yet?
他們找到那個失蹤的孩子了嗎？
現在完成時瞬間動詞即終止性動詞不能與表示一段時間的狀語連用。
常見終止性動詞與延續性動詞 (或狀態動詞) 的對應關係如下:
come / go / arrive / get / reach / move--- be in/at
open --- be open
die --- be dead
close --- be closed
become ---be
borrow --- keep
put on --- wear
buy --- have
leave ----- be away (from)
begin / start ----- be on
fall asleep ---- be asleep
end/finish ----- be over
catch a cold ----- have a cold
join the army ---- be in the army, be a soldier
join the Party---- be in the Party , be a Party member
例：吉姆買這支已有兩年了。
Jim bought this pen two years ago.
Jim has had this pen for two years.
Jim has had this pen since two years ago.
Jim has had this pen since 2007
It is two years since Jim bought this pen.
現在完成時句型中，在表示“最近幾世紀/ 年/ 月以來……”時間狀語中，謂語動詞用現在完成時。
in the past few years/months/weeks/days；over the past few years; during the last three months; for the last few centuries, through centuries; throughout history 等
表示“第幾次做某事，”或在 “It is the best (worst, most interesting ) +名詞 ＋that” 後面跟現在完成時。
例：This is my first time that I have visited China.
This is the most interesting film I have ever seen.
That is the only book that he has written.
have / has been to + 地點 意為“曾去過某地”，暗含目前已不在該地僅表示當事人的一種經歷而已。
have / has gone to + 地點 “到了某地去了”，暗含“已離開原地去了某地”之意，但是否到達了某地尚不確定。
如：He has gone to Shanghai.
他去了上海。
He has been to Shanghai.
他去過了上海。
