        考點(diǎn)分析

        動(dòng)詞完成式包括現(xiàn)在完成時(shí)、過(guò)去完成時(shí)、將來(lái)完成時(shí)、過(guò)去將來(lái)完成時(shí),前三種是方法測(cè)試的重點(diǎn),其考點(diǎn)如下:

        1. 關(guān)于現(xiàn)在完成時(shí)應(yīng)注意以下幾點(diǎn):

        1)注意與現(xiàn)在完成時(shí)相關(guān)的狀語(yǔ)。如:since、for、this year、today等,或表示不確定概念的副詞,如:already、often、never、so far、yet、always等。另外,某些瞬時(shí)動(dòng)詞如ask、begin、come、die、join等,不能跟表示一段時(shí)間的狀語(yǔ)連用。

        2)在“this is +最高級(jí)/序數(shù)詞/ the only+名詞+that”結(jié)構(gòu)中, that 從句中的謂語(yǔ)在完成時(shí)。例如:

        This is the best wine I have ever drunk.

        This is the first time I have visited China.

        2.將來(lái)完成時(shí)表示某時(shí)以前已經(jīng)完成的動(dòng)作。注意與此時(shí)態(tài)連用的時(shí)間狀語(yǔ)the end of…、by this time tomorrow、by then 等,例如:By this time tomorrow you will by home. 另外,在時(shí)間或條件狀語(yǔ)從句中,現(xiàn)在完成時(shí)也可以表示將來(lái)完成時(shí)。例如:your paper when you have finished the test.

        3.過(guò)去完成時(shí)應(yīng)注意以下幾點(diǎn):

        1)過(guò)去完成時(shí)表示過(guò)去某一時(shí)間或動(dòng)作之前完成的動(dòng)作,常用的確狀語(yǔ)有just、ever、by that time、by the end of…、before等。例如:We had just had our breakfast when an old man came to the door.

        2)動(dòng)詞 expect、hope、intend、mean、want、suppose等用過(guò)去完成時(shí),表示過(guò)去的希望意圖、愿望未實(shí)現(xiàn)。例如:They had intended to help, but couldn’t get here in time. (他們本來(lái)打算來(lái)幫忙,不過(guò)沒(méi)來(lái)得及趕到這兒)

        3)在“It was+最高級(jí)/序數(shù)詞/ the only +that”結(jié)構(gòu)的從句中,使用過(guò)去完成時(shí),例如:There was a knock at the door. It was the second time someone had interrupted me that evening.

        考題注釋

       、 本題題干中出現(xiàn)了一個(gè)時(shí)間狀語(yǔ)since, 故應(yīng)用完成時(shí),又由于主句的主語(yǔ)large crowds 為復(fù)數(shù)形式,故排除C)。

       、 在this is the second time…結(jié)構(gòu)中,其后從句中的謂語(yǔ)用現(xiàn)在完成時(shí)。

       、 譯文為:“到這個(gè)月底為止,我們肯定能找到解決問(wèn)題的方法!睍r(shí)間狀語(yǔ)為by the end of this month , 故用將來(lái)完成時(shí)。

       、 本題中before 引導(dǎo)了一個(gè)時(shí)間狀語(yǔ)從句,從句的謂語(yǔ)為過(guò)去時(shí),由此推知,主句的謂語(yǔ)應(yīng)是過(guò)去之過(guò)去,即過(guò)去完成時(shí)。

        答案: 1.B 2.B 3.C 4.C
