英語(yǔ)專(zhuān)八語(yǔ)言知識(shí)題會(huì)直接考查語(yǔ)法知識(shí);專(zhuān)八閱讀理解題和專(zhuān)八翻譯漢譯英中有大量的長(zhǎng)難句，這些句子只有具備一定的語(yǔ)法知識(shí)才能正確分析;下面是小編給大家整理的英語(yǔ)專(zhuān)八語(yǔ)法知識(shí)，大家可以作為學(xué)習(xí)的參考。

時(shí)態(tài)、語(yǔ)態(tài)需要掌握的要點(diǎn)：

1.表達(dá)將來(lái)時(shí)的形式：

(1)在時(shí)間、條件、讓步從句中，一般現(xiàn)在時(shí)代替將來(lái)時(shí)，但要注意區(qū)別從句的類(lèi)型，如：

I’ll tell him when you will ring again. 我告訴他你什么時(shí)候再來(lái)電話。(賓語(yǔ)從句)

比較：I’ll tell him when you ring again.你再打電話時(shí)我告訴他。(狀語(yǔ)從句)

(2)在make sure, make certain, see (to it) 后的that從句中，謂語(yǔ)動(dòng)詞用一般現(xiàn)在時(shí)代替將來(lái)時(shí)，如：

See to it that you include in the paper whatever questions they didn’t know the answer to last time.

(include 不能用will include或其他形式)

2.完成時(shí)是時(shí)態(tài)測(cè)試的重點(diǎn)，注意與完成時(shí)連用的句型和時(shí)間狀語(yǔ)：

(1)by/between/up to/till +過(guò)去時(shí)間、since、by the time/when +表示過(guò)去發(fā)生情況的從句，主句用過(guò)去完成時(shí)。

如：We had just had our breakfast when an old man came to the door.

Between 1897 and 1919 at least 29 motion pictures in which artificial beings were portrayed had been produced.

(表示1919年時(shí)已發(fā)生的情況)

(2)by +將來(lái)時(shí)間、by the time/ when +謂語(yǔ)動(dòng)詞是一般現(xiàn)在時(shí)的從句，主句用將來(lái)完成時(shí)。如：

By the time you arrive in London, we will have stayed in Europe for two weeks.

I hope her health will have improved greatly by the time we come back next year.

(3)by now、since +過(guò)去時(shí)間、in/during/for/over/the past/last few(或具體數(shù)字)years/days/months，主句用現(xiàn)在完成時(shí),如：

The changes that had taken place in air travel during the last sixty years would have seemed completely impossible to even the most brilliant scientists at the turn of the 19th century.

但在it is +具體時(shí)間since/before這一句型中，主句更多的時(shí)候不用完成時(shí)。

It is four years since John left school.

(4)在It is the +序數(shù)詞/形容詞最高級(jí)+that的定語(yǔ)從句中，謂語(yǔ)動(dòng)詞常用現(xiàn)在完成時(shí)。如：

It isn’t the first time that I have found myself in an embarrassing situation.

(5)在no sooner…than…, hardly/scarcely…when…句型中，主句常用過(guò)去完成時(shí)。

3.完成進(jìn)行時(shí)指動(dòng)作在完成時(shí)的基礎(chǔ)上還要繼續(xù)下去。如：

The company has been promising a rise in salary for ages, but nothing has happened.

時(shí)態(tài)、語(yǔ)態(tài)答題思路：

(1)先根據(jù)選項(xiàng)的區(qū)別點(diǎn)確定考題要點(diǎn)為時(shí)態(tài)，然后回到題句中尋找給出的或暗示的時(shí)間狀語(yǔ)，縮小選擇范圍，進(jìn)而選出正確答案;

(2)根據(jù)謂語(yǔ)動(dòng)詞與句子主語(yǔ)或非謂語(yǔ)動(dòng)詞與其邏輯主語(yǔ)的關(guān)系，確定句子是主動(dòng)語(yǔ)態(tài)還是被動(dòng)語(yǔ)態(tài)。
