備考英語(yǔ)四級(jí)考試的時(shí)候，很多人都忽略了語(yǔ)法的備考，其實(shí)語(yǔ)法的備考是貫穿整個(gè)四級(jí)備考的，而且在每個(gè)題型中都會(huì)用到。今天我們?yōu)榇蠹艺砹擞⒄Z(yǔ)四級(jí)語(yǔ)法基礎(chǔ)知識(shí)，一起來看一下吧。

動(dòng)詞(時(shí)態(tài),語(yǔ)態(tài),用法,省略,一致性等)

時(shí)態(tài)

1)現(xiàn)在完成進(jìn)行時(shí)態(tài)(have/has been + -ing 分詞構(gòu)成): 動(dòng)作或狀態(tài)從過去某時(shí)開始,繼續(xù)到現(xiàn)在,可能繼續(xù)下去,也可能剛剛結(jié)束.

I’ve been writing letters for an hour.

I’ve been sitting in the garden.

2)過去完成進(jìn)行時(shí)(由had been + ing分詞構(gòu)成): 過去某個(gè)時(shí)刻以前一直在進(jìn)行的動(dòng)作

3)將來完成進(jìn)行時(shí): 將來某個(gè)時(shí)刻以前一直在進(jìn)行的動(dòng)作.

語(yǔ)態(tài)

可以有兩種被動(dòng)結(jié)構(gòu)的類型,例如:

He was said to be jealous of her success.

It was said that he was jealous of her success.

能同時(shí)適用于上述兩個(gè)句型的'主動(dòng)詞通常都是表示“估計(jì)”,“相信”等意義的動(dòng)詞,常見的有assume,believe,expect,fear,feel,know,presume,report,say,suppose,understand等.

It is supposed that the ship has been sunk.

The ship is supposed to have been sunk.

擔(dān)當(dāng)be supposed to 與不定式的一般形式搭配時(shí)往往表示不同的意義.例如:

Why are you driving so fast in this area? You are supposed to know the speed to know the speed limit. (你應(yīng)該曉得速度限制)
