現在完成時
現在完成時用來表示之前已發生或完成的動作或狀態，其結果的確和現在有聯系。動作或狀態發生在過去但它的影響現在還存在；也可表示持續到現在的動作或狀態。其構成： have (has) +過去分詞。
比較過去時與現在完成時
1）過去時表示過去某時發生的動作或單純敘述過去的事情，強調動作；現在完成時為過去發生的，強調過去的事情對現在的影響，強調的是影響。
2）過去時常與具體的時間狀語連用，而現在完成時通常與模糊的時間狀語連用，或無時間狀語。
一般過去時的時間狀語:
yesterday, last week，…ago, in1980, in October, just now, 具體的時間狀語
共同的時間狀語:
this morning, tonight,this April, now, once，before, already, recently，lately
現在完成時的時間狀語
for, since, so far, ever, never, just, yet,till / until, up to now, in past years, always,不確定的時間狀語
3）現在完成時可表示持續到現在的動作或狀態，動詞一般是延續性的，如live, teach, learn, work, study, know.
過去時常用的非持續性動詞有come, go, leave, start, die, finish, become, get married等。
舉例：
I saw this film yesterday.
（強調看的動作發生過了。）
I have seen this film.
（強調對現在的影響，電影的內容已經知道了。）
He has been in the League for three years.
(在團內的狀態可延續)
He has been a League member for three years.
(是團員的狀態可持續)
He joined the League three years ago.
( 三年前入團，joined為短暫行為。)
句子中如有過去時的時間副詞（如 yesterday, last, week, in 1960）時，不能使用現在完成時，要用過去時。
（錯）Tom has written a letter to his parents last night.
（對）Tom wrote a letter to his parents last night.
用於現在完成時的句型
1）It is the first / second time…. that…結構中的從句部分，用現在完成時。
It is the first time that I have visited the city.
It was the third time that the boy had been late.
2）This is the… that…結構，that 從句要用現在完成時.
This is the best film that I've (ever) seen.
這是我看過的最好的電影。
This is the first time (that) I've heard him sing.這是我第一次聽他唱歌。
注意：非延續性動詞的否定形式可以與表示延續時間的狀語連用。即動作不發生的狀態是可以持續的。
（錯）I have received his letter for a month.
（對）I haven't received his letter for almost a month.
比較since和for
Since 用來說明動作起始時間，for用來說明動作延續時間長度。
I have lived here for more than twenty years.
I have lived here since I was born..
注意：並非有for 作為時間狀語的句子都用現在完成時。
I worked here for more than twenty years.
(我現在已不在這里工作。)
I have worked here for many years.
(現在我仍在這里工作。)
小竅門：當現在完成時+一段時間，這一結構中，我們用下面的公式轉化，很容易就能排除非延續動詞在完成時中的誤使。
1)(對) Tom has studied Russian for three years.
= Tom began to study Russian three years ago, and is still studying it now.
2)(錯) Harry has got married for six years.
= Harry began to get married six years ago, and is still getting married now.
顯然，第二句不對，它應改為 Harry got married six years ago.或 Harry has been married for six years.
since的四種用法
1) since +過去一個時間點(如具體的年、月、日期、鍾點、1980, last month, half past six)。
I have been here since 1989.
2) since +一段時間+ ago
I have been here since five months ago.
3) since +從句
Great changes have taken place since you left.
Considerable time has elapsed since we have been here.
4) It is +一段時間+ since從句
It is two years since I became a postgraate student.
延續動詞與瞬間動詞
1) 用於完成時的區別
延續動詞表示經驗、經歷； 瞬間動詞表示行為的結 果，不能與表示段的時間狀語連用。
He has completed the work.他已完成了那項工作。 (表結果)
I've known him since then. 我從那時起就認識他了。(表經歷)
2)用於till / until從句的差異
延續動詞用於肯定句，表示"做……直到……" 瞬間動詞用於否定句，表示"到……，才……"
He didn't come back until ten o'clock.
他到10 點才回來。
He slept until ten o'clock.
他一直睡到10點。
現在完成進行時
一、現在完成進行時的構成方法
現在完成進行時由「have/has + been +現在分詞」構成。
二、現在完成進行時用法
1．現在完成進行的基本用法表示現在以前這一段時間里一直在進行的動作，這動作可能仍在進行，也可能已停止。
例如：

例如：

Susan eyes are red. She has been crying. 蘇姍一直在哭，眼睛都哭紅了。
現在完成時與現在完成進行時的區別

例如：
I have waited for two hours. 我等了兩小時。（陳述事實）
I have been waiting for two hours. 我等了兩個小時。（等得好辛苦）
2. 現在完成進行時通常用來談論較短暫的動作或情況，若要談論時間延續較長的動作或情況或永久性情況，則通常用現在完成時。
例如：
He has lived in Paris. 他(一直)住在巴黎。
He has been living in Paris. 他(目前)住在巴黎。
3. 不用於進行時態的動詞通常也不用於現在完成進行時，但它們可以用於現在完成時。
例如：
They』ve been married for twenty years. 他們結婚已二十年了。
The war has lasted for a long time. 這場戰爭持續了很長時間。
4. 現在完成進行時不用於被動語態，若要用可用現在完成時的被動語態代替。
例如：
The house has been painted for a month. 這房子已經粉刷了一個月。
The problem has been studied
