【 #英語口語#導語】英語四六級口語考試主要考查語法的有兩個題型：選詞填空和翻譯。以下是 無 整理的英語四六級口語的語法知識點，歡迎閱讀！
1.英語四六級口語的語法知識點
一、虛擬語氣。應著重復習能引起虛擬語氣的某些介詞、介詞短語和連詞(如lest,incase,otherwise等);一部分表示建議、主張、命令等概念的詞語，由于本身隱含說話人的主觀愿望，其后的主語從句、賓語從句、同位語從句往往采用“should+動詞原形”。
二、獨立主格題。一般說來，在句子中沒有連接詞的情況下，逗號是無力連接兩個句子的，其中一個分句要么是非謂語形式，要么是獨立主格結構。兩種結構都做狀語，不同的是獨立主格結構有自己的邏輯主語。
三、時態。英語中共有16個時態。四級考試中出現最多的是將來完成時、現在完成時、過去完成時和完成進行時。
四、名詞性從句。形容詞性的定語從句是考核的重點，用什么引導詞，引導詞前面的介詞形式，引導詞在從句中做什么成分，從句的語序等均有可能成為考點。此外，主語從句、同位語從句、賓語從句也應適當復習。
五、主謂一致。這類考題靈活性大，需要根據實際情況判斷謂語動詞的單復數形式。
英語四級語法知識點總結：
時態：
過去完成時：表示在過去某一時間點之前已經完成的動作或狀態。
將來完成時：表示在將來某一時間點之前將完成的動作或狀態。
完成進行時：表示從過去某一時間開始一直持續到現在的動作，并且該動作可能仍在進行中。
不定式：
一般形式：表示與謂語動詞同步發生的動作，如“He decided to work harder”。
完成形式：表示發生在謂語動詞之前的動作，如“He pretended not to have seen me”。
被動形式：如“The book is said to have been translated into many languages”。
常考考點：不定式做定語、狀語、充當名詞功能，以及不定式的省略。
動名詞：
定義：具有動作性特征的名詞，如“seeing is believing”。
Ⅰ動詞(時態,語態,用法,省略,一致性等)
時
1)現在完成進行時態 (have/has been + -ing 分詞構成): 動作或狀態從過去某時開始,繼續到現在,可能繼續下去,也可能剛剛結束.
I’ve been writing letters for an hour.
I’ve been sitting in the garden.
2)過去完成進行時(由had been + ing分詞構成): 過去某個時刻以前一直在進行的動作
I’d been working for some time when he called.
We had been waiting for her for two hours by the time she came.
3)將來完成進行時: 將來某個時刻以前一直在進行的動作.
By next summer, he will have been working here for twenty years.
In another month’s time she’ll have been studying here for three years.
4)將來完成時(由shall/will have + 過去分詞構成): 將來某時會業已發生的事.

1. 語態
1) 可以有兩種被動結構的類型,例如:
He was said to be jealous of her success.
It was said that he was jealous of her success.
能同時適用于上述兩個句型的主動詞通常都是表示“估計”,“相信”等意義的動詞,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.
擔當be supposed to 與不定式的一般形式搭配時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. (你應該曉得速度限制)
2) 雙賓語及賓補結構的被動語態
a) 雙賓語結構的被動語態: 雙賓語結構變為被動語態時,可以把主動結構中的一個賓語變為主語,另一個賓語仍然保留在謂語后面,但多數是把間接賓語變為主語.
He was asked a number of questions at the press conference.
Two days were allowed them for making the necessary preparations.
b) 賓補結構的被動語態:
She was called Big Sister by everybody.
Then he was made a squad leader.
He was considered quite qualified for the job.
The room was always kept clean and tidy.
2. 短語動詞
1) Vi + adv
The plane took off two hours late.
2) Vi + prep
They looked round the Cathedral.
3) Vi + prep (有被動語態)
She’s looking after her sister’s children.

4) Vi + adv + prep

5) Vt + O + adv

6) Vt + adv + O (無被動語態)
I am trying to give up smoking.
7) Vt + O + prep
We talked Donald into agreement.
3. 省略
1) 在以as, than, when, if, unless等引導的從句中的省略: 在有些狀語從句中,如果謂語包含有動詞be,主語又和主句的主語一致a),或者主語是it b),就常常可以把從句中的主語和謂語的一部分(特別是動詞be)省略掉.
a) Look out for cars when crossing the street.

英語四級語法知識：不定冠詞的用法
冠詞是虛詞，本身不能單獨使用，也沒有詞義，它用在名詞的前面，幫助指明名詞的含義。英語中的冠詞有三種，一種是定冠詞(the Definite Article)，另一種是不定冠詞(the Indefinite Article)，還有一種是零冠詞(Zero Article)。
不定冠詞a (an)與數詞one 同源，是"一個"的意思。a用于輔音音素前，一般讀作[e]，而an則用于元音音素前，一般讀做[en]。
1) 表示"一個"，意為one;指某人或某物，意為a certain。
A Mr. Ling is waiting for you.
2) 代表一類人或物。
A knife is a tool for cutting with.
Mr. Smith is an engineer.
3) 詞組或成語。
a little / a few / a lot / a type of / a pile / a great many / many a / as a rule / in a hurry / in a minute / in a word / in a short while / after a while / have a cold / have a try / keep an eye on / all of a sudden
英語四級語法知識：定冠詞的用法
定冠詞the與指示代詞this，that同源，有"那(這)個"的意思，但較弱，可以和一個名詞連用，來表示某個或某些特定的人或東西。
英語四級語法涵蓋了多個重要方面，包括虛擬語氣、謂語一致、倒裝結構、非謂語動詞、獨立主格結構、時態和名詞性從句等。虛擬語氣強調說話人的主觀愿望和假想情況，考生應特別注意能引起虛擬語氣的介詞、介詞短語和連詞，如lest、in case、otherwise等。在would rather、wish、as if、it is time that等句型中，需用適當形式表達主觀愿望，同時關注混合虛擬句的使用。
謂語一致方面，靈活度較高，考生需根據實際情況判定謂語動詞的單復數形式。具有生命意義的集合名詞作主語時，謂語動詞多采用復數形式，如people、poultry、militia等。用and連接的成分表示單一概念時，謂語動詞用單數。就近原則也需掌握，主語中含有某些連詞如as well as、besides、in addition to時，謂語動詞的數同第一個主語保持一致。
倒裝結構用于強調或突出，分為全部倒裝和部分倒裝。部分倒裝和全部倒裝的區別在于，部分倒裝是將助動詞或情態動詞移到主語之前，而全部倒裝則是將整個謂語移到主語之前。as在倒裝結構中表示“正如”或“仿佛”，具有連接作用。
非謂語動詞是語法考試中的重點，解題時可從三個方面入手：根據非謂語動詞同其所修飾的名詞或邏輯主語的一致關系，確定使用主動語態或被動語態，然后考慮采用現在分詞、現在分詞被動式或過去分詞。
