在英語(yǔ)實(shí)際應(yīng)用中，并非都會(huì)出現(xiàn)前面提到的時(shí)間狀語(yǔ)幫你決定謂語(yǔ)用什么時(shí)態(tài).高考對(duì)謂語(yǔ)時(shí)態(tài)的考查主要是通過語(yǔ)境來(lái)進(jìn)行的.下面我們來(lái)分析、比較幾種容易用.

一般過去時(shí)與過去進(jìn)行時(shí)的用法比較Yesterdayafternoon,hepaintedmea

picturen(強(qiáng)調(diào)paint

.時(shí)狀語(yǔ)從句和條件語(yǔ)從句中,要用一般時(shí).

在間狀代替將來(lái)時(shí),:用一般現(xiàn)在時(shí)代替一般將來(lái)時(shí),用一般過去時(shí)替過去將來(lái)時(shí),用現(xiàn)進(jìn)行時(shí)代替將來(lái)進(jìn)行時(shí),用現(xiàn)代在在完成時(shí)代替將來(lái)完成時(shí).13/時(shí)與現(xiàn)法比成時(shí)即的生的Taketheumbrellawithyouincaseitrains.whimt0tchTVunlehfi----Don'tallowassehasnishedhishomework.K.Ifheiswt

nomatter加疑問詞以及疑問詞與ever構(gòu)成的合成詞引出的從句中，要用一般現(xiàn)在時(shí)代替一般將來(lái)時(shí).Wherever

geta

warmwelcome.3.有部分動(dòng)詞(主要是短暫性動(dòng)作動(dòng)詞)可以用進(jìn)行時(shí)代替將來(lái)時(shí)，即：用現(xiàn)在進(jìn)行時(shí)代替一般將來(lái)時(shí)，用過去進(jìn)行時(shí)

代替過去將來(lái)時(shí).

五

.

兩

個(gè)特

殊句型的

時(shí)

態(tài)

1.在先行詞被形容詞最高級(jí)修飾的定語(yǔ)從句中，要用完成

2.在先行詞是

the

first/second

time的定語(yǔ)從句中，也要

完成時(shí)

.

This

have

visited

the

museum.Thatwasthesecondtimehehadbeenthere.17時(shí)

.六.值得注意的兩點(diǎn)

1.一般來(lái)說(shuō)，只有延續(xù)性動(dòng)作動(dòng)詞才有進(jìn)行時(shí)態(tài)(包括現(xiàn)在

進(jìn)行時(shí)、過去進(jìn)行時(shí)、將來(lái)進(jìn)行時(shí)、現(xiàn)在完成進(jìn)行時(shí)

、過去完成進(jìn)行時(shí)),如果短暫性動(dòng)作動(dòng)詞、終止性動(dòng)詞和

狀態(tài)動(dòng)詞用在進(jìn)行時(shí)態(tài)中，則不表示動(dòng)作正在進(jìn)行，而是

表示將來(lái)或別的含義.Iwastoldthatshewas

leavingforNewYorkthe

next182.

只有延續(xù)性動(dòng)作動(dòng)詞和狀態(tài)動(dòng)詞才可以與表示一段時(shí)間

的狀語(yǔ)(如：for

3

days,since

lastNovember)連用.
