【知識梳理

(一)含義

現(xiàn)在完成時用來表示現(xiàn)在之前已發(fā)生或完成的動作或狀態(tài)，但其結果卻和現(xiàn)在有聯(lián)系,也就是說,動作或狀態(tài)發(fā)生在過去但它的影響現(xiàn)在還存在。

e.g. Ihave lostmy wallet. (含義是：現(xiàn)在我沒有錢花了。)

Janehas laidthe table.(含義是：已可以吃飯了。)

Michaelhas beenill.(含義是：現(xiàn)在仍然很虛弱。)

He has returned from abroad. (含義是：現(xiàn)在已在此地)

(二)結構

助動詞have /has+動詞過去分詞，主語為第三人稱單數(shù)用has，其他人稱用have。

(三)句型

1、肯定句：主語+have /has+動詞過去分詞+其他。

I have studied English for 5 years.

2、否定句：主語+have /has+not +動詞過去分詞+其他。

We haven’t been there.

3、一般疑問句：Have/Has+主語+動詞過去分詞+其他?

Has he eaten that apple?

4、特殊疑問句：特殊疑問詞+ have /has +主語+動詞過去分詞+其他?

(四)用法

1、現(xiàn)在完成時可以用來表示發(fā)生在過去某一時刻的、持續(xù)到現(xiàn)在的情況,常與for, since連用。

e.g. Mary has been illforthree days.

I have lived heresince1998.

2、現(xiàn)在完成時往往同表示不確定的過去時間狀語連用,如already, yet, just, before, recently, lately等：

e.g. He hasalreadyobtained a scholarship.

I haven’t seen much of himrecently (lately).

We have seen that filmbefore.

Have they found the missing childyet?

3、現(xiàn)在完成時常常與表示頻度的時間狀語連用，如often, sometimes, ever, never, twice, on several occasion等：

e.g. Have youeverbeen to Beijing?

I haveneverheard Bunny say anything against her.

I have used this pen onlythree times. It is still good.

George has met that gentleman onseveraloccasions.

4、現(xiàn)在完成時還往往可以同包括現(xiàn)在時間在內的時間狀語連用，如now, up to these few days/weeks/months/years, this morning/week/month/year, now, just, today, up to present, so far等。

e.g. Peter has written six papersso far.

Man hasnowlearned to release energy from the nucleus of the atom.

There has been too much rainthis year.

The relations between us have been enhanced inthe past few years.

Up to the presenteverything has been successful.

5、現(xiàn)在完成時表示現(xiàn)在之前就已完成的動作,雖然其效果或影響仍然存在但已不再繼續(xù),但是有一些現(xiàn)在完成時的句子，在后面加上for+一段時間，則現(xiàn)在完成時的動作就表示延續(xù)性。

e.g. Thomas has studied Russian. (現(xiàn)在不再學俄語)

Thomas has studied Russianfor three years. (=Thomas began to study Russian three years ago, and is still studying it now.)

6、現(xiàn)在完成時還可以用來表示過去的一個時間到現(xiàn)在這段時間內重復發(fā)生的動作。

e.g. Wehave had four textsthis semester.

現(xiàn)在完成時中的時間狀語：

★already通常用于肯定句中，意為“已經(jīng)”，位于行為動詞之前, be動詞、助動詞之后。有時可放在疑問句句尾，表示驚訝。例如：

We have already cleaned the classroom.

Have you finished it already?

★yet用于疑問句中表示“已經(jīng)”;用于否定句中，表示“還(沒)”。例如：

—Has he found his watch yet?他還沒找到他的表嗎?

—No, not yet. 是,還沒有。

★ever意為“曾經(jīng)”，常用于疑問句或否定句中，位于助動詞和過去分詞之間，表示從過去到目前為止的時間。例如：

Have you ever been there?你曾經(jīng)去過那里嗎?

Nothing has ever happened here.這里未曾發(fā)生過什么事。

★never意為“(曾經(jīng))從未、沒有”,是否定副詞，在句中位于助動詞和過去分詞之間。ever與否定詞not連用相當于never。例如：

I haven’t ever spoken to her. = I have never spoken to her.我從未跟她講過話。

★just意為“剛剛”,用于現(xiàn)在完成時,表示行為剛剛過去,位于助動詞與過去分詞之間。

e.g. He has just come back from school.他剛從學�；貋�。

★just now意為“剛才”,表示過去某時,用于一般過去時,位于句首或句尾均可。e.g. He came from school just now.他剛才從學�；貋�。

★for和since的用法及區(qū)別。for與一段時間連用，since與時間點連用。

注意：since后接過去時的時間狀語或過去時的句子。

e.g. I have been to Shanghai twice since 1970.

I haven’t seen her since she left Shanghai.

I saw Ping Ping six years ago. Since I have never seen her.

★have/has gone to、have/has been to和have/has been in的區(qū)別。

have/ has been to 曾經(jīng)去過,人已經(jīng)回來了

have/ has been in 已經(jīng)在,常與一段時間連用

e.g. She has been to Shanghai before. 她以前曾去過上海。

She has been in Shanghai for ten years. 她在上海10年了。

Has he gone to Qingdao?他去青島了嗎?但不能說Have you gone to Qingdao?
