句子副詞
1. 句子副詞的特點
句子副詞用於修飾句子(而不是修飾某個單詞)，反映說話人的觀點和看法，如 actually, certainly, clearly, definitely, evidently, fortunately, frankly, honestly, luckily, obviously, perhaps, possibly, probably, surely, undoubtedly, unexpectedly 等。
2. 句子副詞在句中的位置
句子副詞通常位於句首(或分句句首)：
Obviously he can’t tell the difference between them. 顯然他無法區別兩者的不同。
I arrived late but luckily the meeting had been delayed. 我遲到了，幸而會議推遲了。
但有些句子副詞也可以出現在句中：
He smiled nastily. He evidently knew something I didn’t. 他發出獰笑，他顯然知道一些我所不知道的事。
高中英語副詞知識點總結(二)
有的句子副詞也可用作其他種類的副詞，不過這往往會導致位置和語義的變化：
Clearly he didn’t say so. 顯然他沒有這樣說。(句子副詞)
He didn’t say so clearly. 他說得沒有那麼清楚。(方式副詞)
Frankly, you are wrong. 說實在的，你錯了。(句子副詞)
He spoke frankly about his past life. 他坦率地談了他過去的生活。(方式副詞)
We can use superlative adverbs to make comparisons:
我們可以用最高級副詞來做比較:
His ankles hurt badly, but his knees hurt worst.
It rains most often at the beginning of the year.
Intensifiers:
強調成分
When we intensify a superlative adverb we often use the in front of the adverb, and we use these words and phrases as intensifiers:
當我們強調最高級副詞時，我們通常在副詞前加the，並且我們用以下單詞和詞組作爲強調成分：
easily - much - far - by far
2017高考英語形容詞知識點一、形容詞是用來描寫或修飾名詞或代詞，說明人或事物的特徵或性質的， 形容詞往往被譯成“···的”。用法如下:
1.做定語。e.g. This is an old house.
2.做表語。e.g.I am sorry to hear that.
3.做賓語不足語。 made her mother angry.
4.形容詞在句中的位置。 形容詞做定語修飾名詞時，放在名詞前面。修飾不定代詞時要放在不定代詞之後。
is a clever girl.
I saw something white in the water.
5.某些形容詞前加上定冠詞the,可以代表一類人或東西，可以用作主語，賓語等。做主語時當複數看待。
old are well looked after.
We all love the beautiful.
二、 形容詞的等級變化
在英語中形容詞有原級，比較級和最高級之分。原級就是它們的原形，比較級和最高級有規則變化和不規則變化。
(一)形容詞的比較級和最高級變化
1.規則變化
單音節詞和部分雙音節詞
(1)一般在詞尾加er,est. hard---harder---hardest great---greater---greatest
(2)以字母e結尾的加r,st. nice---nicer----nicest able---abler----ablest
(3)重讀閉音節中末尾只有一個輔音字母時，雙寫輔音字母，再加er,est.
big---bigger---biggest (另外還有fat， red，hot,wet,sad,mad ,thin )
(4) 以 -y 結尾,但 -y 前是輔音字母的形容詞的比較級和最高級是把 -y 去掉,加 上 -ier 和-est 構成. happy (原形) happier (比較級) happiest (最高級)
(5)雙音節和多音節形容詞的比較級和最高級需用more 和 most 加在形容詞前面來構成。
例如： beautiful (原級) difficult (原級)
more beautiful (比較級) more difficult (比較級)
most beautiful (最高級) most difficult (最高級)
2、 常用的不規則變化的形容詞的比較級和最高級:
原級 比較級 最高級
good better best
many more most
much more most
bad worse worst
little less least
ill worse worst
far farther(further) farthest(furthest)
三、形容詞比較等級的用法:
1、形容詞的比較級用於兩個人或事物的比較,其結構形式如下:
主語+謂語(系動詞)+ 形容詞比較級+than+ 對比成分。例如：Our teacher is taller than we are. 我們老師的個子比我們的高。
比較級前面可以用even, still, yet , any, much, rather, a little, a lot, by far等修飾語用以加強語氣或表示比較程度。
2、形容詞最高級的用法: 形容詞最高級用於兩個以上的人和物進行比較,形容詞最高級 前必須加the,後面多用of……， in……短語表示範圍：其結構形式爲:
主語+謂語(系動詞)+the+形容詞最高級+名詞+表示範圍的短語或從句。
She is the best student in her class. 她是班上最好的學生。
He is the tallest of the three boys.他是三個男孩中最高的一個。
四、 有關比較等級的特殊句型及應注意的問題
1. “比較級 + and + 比較級”或“more and more / less and less + 原級”結構表示“越來越……”的意思，與這類結構搭配的常用動詞有grow, get, become等。
She felt herself becoming more and more nervous.她覺得自己越來越緊張。
it's getting colder and colder.天氣越來越冷。
2. the + 比較級 + of the two + 名詞。表示“兩個中較···的一個'
Jane is the taller of the two children in our family. Jane是我家兩個孩子中較高的。
3. “the + 比較級……，the + 比較級……”，表示“越……，越……”。
The more magazines you sell, the more money you will get.你賣的雜誌越多，你掙的錢就越多。
4.“ + 形容詞 + as...”或“ + 形容詞 + 名詞 + as...”構成，表示同等比較。
2017高考英語虛擬語氣詞知識點一.虛擬語氣用於條件狀語從句中
1. 表示與現在事實相反或不可能發生：條件狀語從句：
一般過去時(虛擬語氣中be→were)
主句用：would(should, could, might)+動詞原形。
Eg:If we had time now, we would read it again.
If I were you, I would work hard.
2. 表示與過去事實相反或不可能發生：條件狀語從句：had+過去分詞;
主句：would(should, could, might)+have+過去分詞。
Eg:If he had taken my advice, he would have succeeded in the test.
If I had known your telephone number then, I would have called you.
3. 表示與將來的事實可能相反或不可能發生：
條件狀語從句：①一般過去時②should +動詞原形③were to+動詞原形;
主句：would(should, could, might)+動詞原形。
Eg:If it should rain, the crops would be saved.
If it were to snow tomorrow, they would not go out.
注：虛擬條件句的特殊情況
(1)混合/錯綜型虛擬語氣
當條件狀語從句表示的行爲和主句表示的行爲所發生的時間不一致時，稱爲'錯綜條件句’，動詞的形式要根據它所表示的時間作出相應的調整。
Eg:If you had followed my advice, you would be better now.
(從句說的是過去，主句是現在)
Eg:If I were you, I would have taken his advice.
(從句是現在，主句是過去)
(2)省略if的虛擬語氣
如果從句中含有were/ should/ had時，則可以把這三個詞置於句首，省略if.採用倒裝語序。
Eg:If it should happen, what would you do?
Should it happen, what would you do?
If he had recognized me, he would have come over.
Had he recognized me, he would have come over.
(3)含蓄虛擬條件句
有時候假設的情況不以if引導的條件從句形式表現出來，
而是通過一個介詞短語，連詞或其他形式表示。
常用的詞或短語有：without, with, but for(要是沒有), otherwise, or, but等。
Eg:Without your help(=If we had not had your help),we could not have succeeded.
But for electricity(=If there were no electricity,there would be no modern industry.
He felt very tired yesterday, or/ otherwise he would have attended the party.
(4)在if it were( had been )not for ….句型中的虛擬語氣
虛擬語氣也常用於'if it were/(had been) not for ….’句型中，意爲'要不是由於…’。
Eg:If it were not for peace, we could not be living a happy life today.
If it had not been for your timely help, I would have gone bankrupt.
二.虛擬語氣用在名詞性從句中
1.主語從句中的虛擬語氣
這種虛擬語氣主要用在it is+形容詞(名詞，過去分詞)+that+主語+should+動詞原形(should可以省略)這種結構中。
常見的這類形容詞有：advisable, anxious, better, desirable, surprising, natural, necessary, strange, important, regretful.
常見的這類過去分詞有：decided, demanded, recommended, requested, desired, required, ordered, suggested.
常見的這類名詞有：duty, pity, no surprise, no wonder, regret, shame.
Eg:It was suggested that he(should)join the club activities.
It is strange (surprising, disappointing) that she (should) not have been invited.
It is a pity that he (should) refuse to accept the offer.
2.賓語從句中的虛擬語氣
①wish後面所跟賓語從句謂語動詞用虛擬語氣(意爲要是，但願…就好了)，
其形式主要有三種：
表示對現在情況的虛擬：wish後接一般過去時的從句
表示對過去情況的虛擬：wish後接過去完成時/should，could have done
表示對將來情況的虛擬：wish後接would，could+動詞原形
Eg:I wish it were spring all year round.
I wish it would be fine tomorrow.
She wished she had stayed at home.
② 在表示建議，命令，要求等動詞後的從句要用(should)+動詞原形。
此類動詞有：suggest, advise, propose, demand, require, insist(要求), order, prefer, command, ask, request.
Eg:The teacher ordered that all the books (should) be handed in on time.
注：當suggest表示'暗示，說明’之意;insist表示'堅持認爲，堅持說’之意時，從句不用虛擬，用正常的陳述語氣。
Eg:The man insisted that he had never stolen the money.
The smile on his face suggested that he was satisfied with life.
3. 表語從句和同位語從句中的虛擬語氣在表示建議，命令，要求的名詞後的表語從句或同位語從句中的謂語動詞要用
(should)+動詞原形。常見名詞有：advice, desire, request,
demand, proposal, suggestion, preference, requirement, order.
Eg:He gave orders that the guests (should) be hospital entertained.
His proposal is that we (should) get rid of the bad habits.
三.虛擬語氣在其他情況中的使用
1.在as if/ as though引導的狀語從句中，若從句與事實相反，則要用虛擬語氣。
其形式如下：
主語+as if/ though +主語+一般過去時(從句的動作與主句同時發生)
主語+as if/ though +主語+would/could+動詞原形(從句的動作相對主句來說在將來發生)
主語+as if/ though +主語+過去完成時(從句的動作先發生於主句動作之前)
Eg:He talks as if he knew all about it.
She speaks English well as if he had studied in America.
He learns English so hard as if he would go abroad.
2.在it is (high) time that …句型中也用虛擬語氣，從句常用過去式，有時也用should +動詞原形，表示早該做而沒做的事，含建議的意味。
Eg:It is time that we went home.
注：此句型中，注意與'It/This is the +序數詞+time that+現在完成式的區別。
Eg:This is the first time that I have been here.
d rather後接動詞原形，但接從句時要用虛擬語氣(寧願，但願)。
Would rather +主語+一般過去時(表示與現在或將來相反)
Would rather +主語+過去完成時(表示與過去相反)
Eg:I’d rather he didn’t go now.
I’d rather you hadn’t done it.
only後接從句也用虛擬語氣，其形式與wish的用法一致。
5. 動詞hope, intend, mean, plan, want, think等詞用過去完成的形式，表示的意思爲'本想，本打算，本認爲’
Eg:He had meant to buy the furniture last week, but it rained.(他上週本打算去買那件傢俱，但卻下雨了)
非真實條件句中的虛擬語氣(以動詞do爲例)
