　　A. 現(xiàn)在完成時(shí)表示一個(gè)過(guò)去開(kāi)始的狀態(tài)或動(dòng)作持續(xù)到現(xiàn)在并可能繼續(xù)持續(xù)下去，常同表示一段時(shí)間的狀語(yǔ)連用。如so far, up to now, since, for a long time等。

　　--He has worked as a teacher for many years.

　　--Up till now, nothing has gone wrong.

　　B. 現(xiàn)在完成時(shí)表示一個(gè)過(guò)去發(fā)生的對(duì)現(xiàn)在仍有影響的動(dòng)作或事件。常與不確定的過(guò)去時(shí)間狀語(yǔ)連用，如yet, just, before, recently等;也同表示頻度時(shí)間狀語(yǔ)連用，如often, ever, never, sometimes, several times等;還可同包括現(xiàn)在時(shí)間在內(nèi)的時(shí)間狀語(yǔ)連用，如now, today, this morning等。但不能同特定的過(guò)去時(shí)間狀語(yǔ)連用(last year , in 1997等)。

　　--David and Jenny had known each other for a long time before their marriage.

　　--They had got everything ready before the party began.

　　Note: 與現(xiàn)在完成時(shí)截然不同的是過(guò)去完成時(shí)可以與表示具體過(guò)去的時(shí)間狀語(yǔ)連用。

　　--He said that he had seen her the day before yesterday.

　　3) 將來(lái)完成時(shí)：

　　3. 時(shí)態(tài)的呼應(yīng)

　　時(shí)態(tài)的呼應(yīng)又稱時(shí)態(tài)一致(Sequence of Tenses)，指的是某些從句里的動(dòng)詞謂語(yǔ)時(shí)態(tài)必須和主句里的時(shí)態(tài)保持一致。

　　如果主句里的謂語(yǔ)動(dòng)詞是過(guò)去時(shí)態(tài)(過(guò)去時(shí)或過(guò)去完成時(shí))，那么從句的謂語(yǔ)動(dòng)詞時(shí)態(tài)也相應(yīng)地要用過(guò)去時(shí)。時(shí)態(tài)的呼應(yīng)主要發(fā)生在間接引語(yǔ)和賓語(yǔ)從句中，但其他從句有時(shí)也存在時(shí)態(tài)一致的問(wèn)題。

　　--He explained that he had learned Chinese for many years.(現(xiàn)在完成時(shí)變?yōu)檫^(guò)去完成時(shí))

　　--He said he had been collecting materials on that subject for a long time.(過(guò)去進(jìn)行時(shí)變?yōu)檫^(guò)去完成進(jìn)行時(shí))

　　--He told me that they would have completed that project by the end of the year.(將來(lái)完成時(shí)變?yōu)檫^(guò)去將來(lái)完成時(shí))

　　雖然主句用了過(guò)去時(shí)等，如果從句表示的是科學(xué)真理、客觀事實(shí)或某人(物)的經(jīng)常性特點(diǎn)時(shí)，其時(shí)態(tài)可以不必遵守時(shí)態(tài)呼應(yīng)的規(guī)則而仍用一般現(xiàn)在時(shí)。

　　--Galileo proved that the earth revolves round the sun.

　　--The teacher told the students that knowledge is power.

　　如果從句中有一個(gè)表示絕對(duì)過(guò)去時(shí)間的狀語(yǔ)，就不必把一般過(guò)去時(shí)變?yōu)檫^(guò)去完成時(shí)。

　　--He said that he joined the Red Army in 1933.
