過(guò)去完成時(shí)與一般過(guò)去時(shí)的區(qū)別
雖然這兩種時(shí)態(tài)都表示過(guò)去發(fā)生的動(dòng)作或存在的狀態(tài),但在使用時(shí)應(yīng)注意以下幾點(diǎn)：1.時(shí)間狀語(yǔ)不同：過(guò)去完成時(shí)在時(shí)間上強(qiáng)調(diào)“過(guò)去的過(guò)去”；而一般過(guò)去時(shí)只強(qiáng)調(diào)過(guò)去某一特定的時(shí)間.比較：They had arrived at the station by ten yesterday.They arrived at the station at ten yesterday.2.在沒(méi)有明確的過(guò)去時(shí)間狀語(yǔ)作標(biāo)志時(shí),謂語(yǔ)動(dòng)詞動(dòng)作發(fā)生的時(shí)間先后須依據(jù)上下文來(lái)判斷：先發(fā)生的用過(guò)去完成時(shí),后發(fā)生的則用一般過(guò)去時(shí).She was very happy.Her whole family were pleased with her,too.She had just won the first in the composition competition.3.當(dāng)兩個(gè)或兩個(gè)以上接連發(fā)生的動(dòng)作用 and 或 but 連接時(shí),按時(shí)間順序,只需用一般過(guò)去時(shí)來(lái)代替過(guò)去完成時(shí)；另外,在 before ,after ,as soon as 引導(dǎo)的從句中,由于這些連詞本身已經(jīng)表示出時(shí)間的先后,因此也可以用過(guò)去時(shí)來(lái)代替過(guò)去完成時(shí).He entered the room,turned on the light and read an evening paper.
