引導語：下面小編將為大家帶來英語六級考試語法鞏固彙總，希望能夠幫助到您，謝謝您的閱讀。
一、方式狀語從句
方式狀語從句通常由as, (just) as…so…, as if, as though引導。
, (just) as…so…引導的方式狀語從句通常位於主句後，但在(just) as…so…結構中位於句首，這時as從句帶有比喻的含義，意思是"正如…"，"就像"，多用於正式文體，例如：
Always do to the others as you would be done by.
你希望人家怎樣待你，你就要怎樣待人。
As water is to fish, so air is to man.
我們離不開空氣，猶如魚兒離不開水。
Just as we sweep our rooms, so we should sweep backward ideas from our minds.
正如打掃房屋一樣，我們也要掃除我們頭腦中落後的東西。
2. as if, as though
兩者的意義和用法相同，引出的狀語從句謂語多用虛擬語氣，表示與事實相反，有時也用陳述語氣，表示所說情況是事實或實現的可能性較大。漢譯常作"彷彿……似的"，"好像……似的"，例如：
They completely ignore these facts as if (as though) they never existed.
他們完全忽略了這些事實，就彷彿它不存在似的。(與事實相反，謂語用虛擬語氣。)
He looks as if (as though) he had been hit by lighting.
他那樣子就像被雷擊了似的。(與事實相反，謂語用虛擬語氣。)
It looks as if the weather may pick up very soon.
看來天氣很快就會好起來。(實現的可能性較大，謂語用陳述語氣。)
說明：as if / as though也可以引導一個分詞短語、不定式短語或無動詞短語，例如：
He stared at me as if seeing me for first time.
他目不轉睛地看著我，就像第一次看見我似的。
He cleared his throat as if to say something.
他清了清嗓子，像要說什麼似的。
The waves dashed on the rocks as if in anger.
波濤衝擊著岩石，好像很憤怒。
二、主謂倒裝
主語和謂語是句子的核心，它們之間有兩種語序：一是主語在謂語之前稱為自然語序(Natural Order);二是主語在謂語之後則稱為倒裝語序(Inverted Order)。而倒裝語序中又有全部倒裝(Full Inversion)和部分倒裝(Partial Inversion)兩種情況。
首先，在全部倒裝的句子中，要把整個謂語放在主語的前面去而構成倒裝語序。
例如：
There are large numbers of students in the lecture hall.
(在There be…的句式中，There只是個引導詞而不是主語，真正的主語是後面作表語的名詞或者名詞短語。因此，There be…的句式都是全部倒裝的句子。)演講廳裡有大量的學生。
When he ran to the door, there stood a mid-aged man with a lantern in his hand .
(此句是為了"描述情節的需要"，把倒裝當著修辭的手段而寫成了全部倒裝句。句子的主語是a mid-aged man，謂語是stood 。)當他向房門跑去時，那兒正立著一位手裡拿著一盞燈籠的中年男人。
另外，在部分倒裝的句子中，只把謂語的一部分(如情態動詞、助動詞、或是系動詞be)放到主語的前面去，構成倒裝語序。例如：
Are you going to take part in the football match against Accounting Department on Friday afternoon? (句子的謂語是are going to take part，are是句子的謂語的一部分;句子的主語是you 。所以，此句是部分倒裝的句子。疑問句都是部分倒裝句。)你打算去參加星期五與會計系進行的足球賽嗎?
Hardly could he finish his test paper when the school bell rang .(由於語法要求的原因，本句寫成了部分倒裝的句子。它的自然語序應該是：When the bell rang, he could hardly finish his test paper.)他還未做完試卷，下課鈴就響了。
瞭解了倒裝語序的構成情況後，我們再來看看倒裝語序在各種不同類句子中的使用情況：
A. 在疑問句中
各種疑問句一般地說都是倒裝語序。例如：
Will they come to see us this weekend ? 這個週末他們將來看我們嗎?
Are you talking about the film you saw last Monday ?
你們是在談論你們上週一看的那部電影嗎?
Can you speak another foreign language except English?
除開英語，你還能說另一種外語嗎?
Where did you buy the dictionary, in the book store nearby or in Xinhua bookstore?
你在哪兒買的這本詞典，是在附近的書店還是在新華書店?
She is not a student, isn‘t she ? 她不是個學生，對嗎?
B. 在感嘆句中
某些感嘆句也用倒裝語序。例如：
Isn‘t it a beautiful garden ! 多麼美麗的花園啊!
What a beautiful garden it is ! 多麼美麗的花園啊!(在這種句式中，主語在謂語之前，屬於自然語序。對於主語和謂語而言，語序沒有倒裝。)
Have you ever seen such a naughty kid like him !
你見過那個孩子像他這麼調皮!
C. 在陳述句中
陳述句在一般情況下用自然語序;但由於英語語法的某些原因，陳述句也要使用倒裝語序。這些原因大致可以歸納
1. 為了避免句子部分內容不必要的重複，常用"so + be動詞(助動詞、情態動詞)+主語"或"neither / nor + be動詞(助動詞、情態動詞)+主語"的'倒裝句式。其中第一個句式表示"與前面所述的肯定情況相同"， 第二個句式表示"與前面所述的否定情況相同"。例如：
His brother is a college student; so is mine.
他弟弟是大學生，我弟弟也是。
His brother is not a college student; nor is min .
他弟弟不是大學生，我弟弟也不是。
He used to have his further study abroad; so did I.
他曾去國外深造過，我也去過。
He didn‘t use to have his further study abroad; neither did I.
他沒去國外深造過，我也沒有。
One of my friends can speak three foreign languages; so can his wife.
我的一個朋友會說三門外國語，他的妻子也會。
One of my friends cannot speak three foreign languages; neither can his wife .我的一個朋友不會說三門外國語，他的妻子也不會。
They are now preparing for their final examinations; so are we .
他們正在為期末考試作準備，我們也一樣。
They are not now preparing for their final examinations; nor are we .
他們沒在為期末考試作準備，我們也沒有。
2.具有否定意義的詞或短語置於句首時(除否定詞修飾主語外)，句子一般要寫成部分倒裝句。這類詞或短語常見的有：not, never, seldom, hardly, rarely, scarcely, by no means, under no circumstances, in no way, at no time, no sooner … (than), hardly … (when), not only … (but also), not until… ,等。例如：
Hardly had she sat down when she heard someone knocking at the door .
她還沒來得及坐下來，就聽見有人敲門。
Not until twelve o‘clock did he go to bed last night .
他昨晚直到十二點鐘才睡覺。
Never have my sisters been to Hong Kong before .
我的妹妹們以前從未去過香港。
No sooner had I returned home from New Zealand than I bought a house and went to live there.我從紐西蘭一回國，就買了一棟房子並在那兒住下了。
So far as I know, seldom does Mary come back to see her mother.
就我所知，瑪利幾乎很難回來看她媽媽。
Scarcely a drop of rain fell here last fall . (否定詞修飾主語時，句子不用倒裝。) 去年秋天，這兒幾乎沒下一滴雨。
三、 would rather
would rather do
would rather not do
would rather… than… 寧願……而不願。
還有would sooner, had rather, had sooner都表示"寧願"、"寧可"的意思。
If I have a choice, I had sooner not continue my studies at this school.
I would rather stay here than go home. = I would stay here rather than go home.
典型例題
----Shall we go skating or stay at home?
----Which ___ do?
A. do you rather B. would you rather C. will you rather D. should you rather
答案B。本題考查情態動詞rather的用法，would rather +do sth 意為"寧願"，本題為疑問句，would 提前，所以選B。
四、had better
had better 相當於一個助動詞，它只有一種形式，它後面要跟動詞原形。
had better do sth
had better not do sth
It is pretty cold. You‘d better put on my coat.
She‘d better not play with the dog.
had better have done sth表示與事實相反的結果，意為"本來最好"。
You had better have come earlier.
五、並列結構
並列連詞引導兩個並列的句子。
1) and 與or
判斷改錯：
(錯) They sat down and talk about something.
(錯) They started to dance and sang.
(錯) I saw two men sitting behind and whisper there.
(對) They sat down and talked about something.
(對) They started to dance and sing.
(對)I saw two men sitting behind and whispering there.
解析：
第一句： and 連線兩個並列的謂語，所以 talk 應改為 talked。
第二句：and 連線兩個並列的動詞不定式，第二個不定式往往省略to，因此sang 應改為 sing。
第三句：and 連線感觀動詞saw 後面的用作的賓補的兩個並列分詞結構，因此whisper應改為whispering。
注意：and 還可以和祈使句或名詞片語連用表示條件。(or也有此用法)
Make up your mind, and you‘ll get the chance.
= If you make up your mind, you‘ll get the chance.
One more effort, and you‘ll succeed.
= If you make one more effort, you‘ll succeed.
2) both …and 兩者都
She plays (both) the piano and the guitar.
3) not only…but (also), as well as不但…而且)
She plays not only the piano, but (also) the guitar.
注意： not only… but also 關聯兩個分句時，一個分句因有否定詞not 而必須倒裝。
Not only does he like reading stories, but also he can even write some.
4) neithe…nor 意思為"既不……也不……"謂語動詞采用就近原則，與nor後的詞保持一致。
Neither you nor he is to blame.
六、一般現在時表將來
1)下列動詞：come, go, arrive, leave, start, begin, return的一般現在時表將來。這主要用來表示在時間上已確定或安排好的事情。
The train leaves at six tomorrow morning.
When does the bus star? It stars in ten minutes.
2)倒裝句，表示動作正在進行，如：
Here comes the bus. = The bus is coming.
There goes the bell. = The bell is ringing.
3)在時間或條件句中。
When Bill comes (不是will come), ask him to wait for me.
I‘ll write to you as soon as I arrive there.
4)在動詞hope, take care that, make sure that等後。
I hope they have a nice time next week.
Make sure that the windows are closed before you leave the room.
