高二英語必掌握知識點總結1
一、不定式做主語：
1、不定式做主語一般表示具體的某次動作。===動名詞doing 表示習慣的，經常的動作。
e.g: To finish the building in a month is difficult.
To do such things is foolish.
To see is to believe. (對等)
注: 1). 不定式作主語時,謂語用單數
2). 當主語較長，謂語較短時，常用it做形式主語，而將不定式放到謂語的後面。
it做形式主語，不定式放在謂語動詞之後常用於下列結構中：
(1)It is/was +adj.+of sb. to do…
(2) It is +adj.+for sb.+to do…
It is easy / difficult / hard / foolish / unwise / right / wrong /unnecessary
(3) it is +a +名詞+ to do...
It is a pity / a pleasure / a pleasant thing / one’s duty / an honor / ashame / a crime / no easy job… to do
It takes (sb.) some time / courage / patience …to do…
It requires courage / patience / hard work… to do…
_注意: probable 和 possible 均可作表語，但possible可以用不定式作真實主語，而probable不能用不定式作真實主語。
It is probable for him to come to the meeting.(錯)
It is possible for him to come to the meeting.
It is possible / probable that he will come to the meeting.
二、不定式做表語
主語是以aim duty hope idea intention plan job suggestion wish purpose task等爲中心詞的名詞詞組 或以 what 引導的名詞性從句表示，後面的不定式說明其內容, 不定式作表語常表示將來或現在的動作或狀態。
eg :My idea is to climb the mountain from the north.
Your mistake was not to write that letter.
What I would suggest is to start work at once.
三 、動詞不定式作賓語
以不定式結構爲賓語的動詞有：
ask, agree, care, choose, demand, decide, expect, fail, help, hope, learn,manage, offer, plan, prepare, pretend, promise, refuse, want,wish等只能用動詞不定式作賓語
口訣(接不定式作賓語的動詞)
想要學習 早打算( want learn plan)
快準備 有希望( prepare hope wish expect)
同意否 供選擇(agree offer choose)
決定了 已答應(decide be determined promise)
盡力去 着手做(manage undertake)
別拒絕 別假裝(refuse pretend)
失敗不是屬於你(fail)
refused to lend me his pen.
We hope to get there before dark.
The girl decided to do it herself.
_注意:某些及物動詞可用-ing也可用動詞不定式作賓語但意義不同的有
stop go on remember forget
regret try mean can’t help
be used to

1.倒裝句的定義：英語最基本的詞序是主語在謂語動詞的前面。
如果把謂語動詞放在主語前面，就叫做倒裝。
2. 倒裝句的構成
a) 完全倒裝
將句子的主語和謂語完全顛倒過來，稱之爲完全倒裝。
Are you from here? 你是本地人嗎?
Now comes the chance. 機會來了。
b) 部分倒裝
只將助動詞、系動詞或情態動詞移至主語之前，謂語的其他部分仍保留在主語的後面，稱之爲部分倒裝。例如：
Has he come? 他來了嗎?
Seldom have we felt as comfortable as here. 我們難得像在這裏這麼舒服。
Only in this way can we do the work better.
只有這樣我們才能把工作做得更好。
3. 倒裝的原因
a) 句子語法結構的需要。例如：
Did you attend the meeting? 你參加會議了嗎?
Long live peace! 和平萬歲!
b) 一些句型的固定用法。例如：
Such were his last words. 他最後的話就是這樣。
c)強調的需要。倒裝以後，句子更加流暢生動。例如：
Never before have we seen such a sight. 以前我們從來沒有見過這樣的情景。
Before us lay a lot of difficulties. 在我們前面有很多困難。
Often did we warn them not to do so. 我們曾多次警告他們不要這樣做。
4. 倒裝句的基本用法
a) 構成疑問句(除對主語或主語之定語提問的特殊疑問句外)：
When are we going to drink to your happiness? 我們什麼時候喝你們的喜酒?
Have you seen the film? 你看了那部_嗎?
b) 在以here, there, now, then, in, away, up down等副詞開頭的句子中:
Away went the crowd one by one. 人們一個一個地離去。
Here comes our teacher! 我們的老師來了!
c) 副詞only+狀語放在句首時:
Only then did he realize his mistakes . 只有在那時他才認識到自己的錯誤。
Only in this way can you learn maths well . 只有用這種方法你才能學好數學。
d) 含有否定意義的副詞或連詞(如little, hardly, never, rarely, no sooner…than等)放在句首時:
Little did I think that he could be back alive. 我沒有想到他竟能活着回來。
Not until New Year’s Day shall I give you a gift. 我要到元旦那天才能給你禮物。
Hardly had the train arrived at the station when we ran towards thesleeping car looking for our guests.
火車剛一進站，我們就跑到臥車那兒去找我們的客人。
e) 副詞so或 neither(nor)在句首:
He is interested in pop-songs, and so am I.他對流行歌曲感興趣，我也如此。
He hasn’t been to the countryside, neither does he want to gothere.他沒有去過農村，他也不想去那裏。
f) 在方式狀語thus開頭的句子中及程度狀語so放句首:
Thus ended his life. 這樣結束了他的生命。
So loudly did he speak that even people in the next room could hear him .他講話的聲音那樣大，連隔壁屋子裏的人都聽得見。
2. so作“也”講時，引導的句子用倒裝語序，例如：
He went to the film last night. So did I. 他昨天晚上去看_了，我也去了。
如不作“也”講而只起連詞作用，表示一種結果的意思，句子就要用正常語序。例如：
His mother told him to go to the film. So he did. 他母親叫他去看_，他就去了。
“He is a tall thin man.” “So he is.” “他又高又瘦。” “確實如此。”
3. 某些讓步狀語從句往往把表語提到主語前面或放在句首，以構成倒裝結構。例如：
No matter how interesting the book is，he doesn't like to readit.不管這本書多有趣，他都不想看。
However hard a solid may be，we can change its shape.不管一個固體有多硬，我們都可以改變其形狀。
Young as he is, he knows a lot. 雖然他年輕，卻知道很多東西。
4. 在虛擬語氣中，如果非真實條件句省略if，須將主句中的were, had和should等助動詞和主語顛倒形成部分倒裝。例如：
Were he younger (= If he were younger), he would learn skating.假如他年輕一些，他就會去學溜冰。
Should they forget (= If they should forget) to bring a map with them, theywould get lost in the woods
如果他們忘記帶一張地圖的話，他們就會在深林裏迷路。
Had they realized (= If they had realized) how important the task was, theywouldn’t have refused to
accept it. 假如他們認識到這個任務是多麼重要的話，他們就不致於拒絕接受這項任務。

1.非謂語動詞的構成和語法功能及用法對比。
2.非謂語動詞的完成式、被動式的用法和特點。
3.非謂語動詞的複合結構及否定形式。
4.不定式與動名詞，動名詞與現在分詞，現在分詞與過去分詞，分詞作狀語與獨立結構等用法對比。
5.不定式和動名詞在及物動詞後作賓語的區別是考查的熱點。
6.過去分詞作定語，不定式和分詞作賓語補足語的用法。
7.不定式標誌to和介詞to的用法判斷等。
8.帶to與不帶to的不定式的用法及區別。
考點一、考查謂語動詞與非謂語動詞的識別
英語句子至少應該包括主語與謂語兩部分, 而多數情況下謂語都由動詞來充當。如果對句子成分劃分不清，把謂語動詞與非謂語動詞混淆,做題效果可想而知。要克服這一毛病，關鍵在於正確判斷、識別動詞在句中是否充當謂語。如：
1. The children (play) _____ the violin over there will go on the stagenext week.
根據句子結構，我們可以看出這是一個簡單句。主語是The children，謂語部分是will go on thestage，動詞play顯然在句中不作謂語，應用非謂語動詞形式。依據play與它的邏輯主語children之間的主動關係以及拉小提琴動作正在進行，可以判斷用現在分詞作定語修飾children，意爲“正在那邊拉小提琴的小孩”，因而正確答案爲playing。
考點二、考查作狀語的非謂語動詞的辨析
作狀語的非謂語動詞主要考查其各種形式的辨析，即是選擇動詞不定式、現在分詞還是過去分詞作狀語, 不同的狀語對非謂語動詞的要求不同。動詞不定式主要作目的、結果和原因狀語;現在分詞和過去分詞主要作時間、原因、條件、讓步、方式和伴隨狀語，兩者不同之處在於：現在分詞作狀語時，現在分詞的動作就是句子主語的動作,即它的邏輯主語就是句子的主語，它們之間的關係是主動關係，而過去分詞作狀語時，雖然它的邏輯主語也是句子的主語，但過去分詞表示的動作是句子主語承受的動作，它們之間的關係是被動關係。請看下面例題：
1.____tired of Tom’s all-talk-no-action attitude, Julia decided to do thejob all by herself.
A) To get B) To have got
C) Getting D) Have got
一般來說，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。據此，首先可以確定這是一個簡單句，非謂語動詞短語放在句首作狀語。依據非謂語動詞短語get tiredof與其邏輯主語Julia之間的主動關係，以及謂語動詞與非謂語動詞所表示的動作幾乎同時發生，沒有明顯的先後順序，可以斷定應用現在分詞一般式作原因狀語,即“由於厭倦了Tom只說不做的工作態度”，故正確答案爲C。
考點三、考查非謂語動詞邏輯主語的分辨
非謂語動詞雖然在句中不作謂語，但仍然有自己邏輯上的主語。歷年各種考試的重點在於正確分辨非謂語動詞的邏輯主語是什麼，兩者之間是主動關係還是被動關係，特別是非謂語動詞作狀語的時候。我們知道，當非謂語動詞放在句首作狀語的時候，一般來說，它的邏輯主語就是句子的主語，那麼，當它的邏輯主語不是句子的主語時，又會出現什麼現象呢?請看下面例題：
1. The last bus (go)____, we had to walk home.
2. Weather (permit)____, the spaceship will be launched tomorrowevening.
這兩個非謂語動詞短語的邏輯主語都不是句子的主語，而是分別有它自己的邏輯主語，即“是末班車開走了，而不是我們走了”,“是天氣允許,而不是飛船允許”，這種現象或結構就是獨立主格結構。依據非謂語動詞與其邏輯主語的主動關係,正確答案分別爲havinggone和permitting。

Worried about the journey, I was unsettled for the first few days.
Well-known for their expertise, his parents’ company …..
Confused by the new surroundings, I was hit by the lack of fresh air.
Exhausted, I slid into the bed and fell fast asleep.
過去分詞作狀語：過去分詞作狀語時，說明動作發生的背景或情況，其等同於一個狀語從句。vt 過去分詞作狀語時與主句主語構成被動關係，表示被動和完成，vi過去分詞表示狀態或動作的完成。
Heated , water changes into steam .
The professor came in, followed by a group of young people .
1 作原因狀語，等於as / since / because 引導從句
Moved by what she said ,we couldn’t help crying . = ( As we are moved bywhat she said …
2 作時間狀語，等於when 引導時間從句，如果分詞表示的動作與謂語的動作同時發生，可在分詞前加when/ while / until等使時間意義更明確。
When heated , water can be changed into steam .
Seen from the hill ,the park looks very beautiful .= ( When the park isseen from the hill…
3 作條件狀語等於 if / whether 引導從句

4 作方式或伴隨狀語
The actress came in , followed by her fans .
She sat by the window , lost in thought .
5 作讓步狀語
Much tired ,he still kept on working .=(Although he was tired ,) he ….
6 獨立主格結構： 當分詞的邏輯主語不是主句主語時，分詞可以有自己獨立的邏輯主語，這種結構稱爲獨立主格結構。常用來表示伴隨情況。
The boy rushed into the classroom , his face covered with sweat .
All things considered ,your article is of great value than hers .
Rewrite with proper conjunctions
Example : United we stand, divided we fall.
If we are united, we will stand, but if we are divided,we will fall.

現在分詞與過去分詞作狀語
現在分詞作狀語時，與其邏輯主語之間是主動關係，;而過去分詞與其邏輯主語之間則表示被動關係。
Seeing these pictures, I couldn’t help thinking of those days when I was inBeijing . Seen from the top of a thirty-storeyed building, Beijing looks moremagnificent. (see)
選擇現在分詞還是過去分詞，關鍵看主句的主語。如分詞的動作是主句的主語發出，分詞就選用現在分詞，反之就用過去分詞。例如：
Used for a long time, the book looks old.
由於用了很長時間，這本書看上去很舊。
Using the book, I find it useful.
在使用的過程中，我發現這本書很有用
注意:1.系表示主語所處的狀態
_____ in thought, he almost ran into the car in front of him. ( lose)
______ in white, she looks more beautiful.( dress)
be lost in
be dressed in
be interested in
be devoted to
be supposed to? be caught in the rain
be seated in
be prepared for
be determined to
2.不與主語保持一致的固定結構
generally speaking 一般說來
strictly/ frankly speaking 嚴格地說/坦白地說
judging from 從…判斷
all things considered 從整體來看
taking all things into consideration 全面看來
例如：Judging from his face, he must be ill.從他的臉色看，他一定是病了。
Generally speaking, dogs can run faster than pigs.
總的來說，狗比豬跑得快。 (speaking 不是dogs 的動作)
