高三英語知識點1
the most commonly used and simplest holiday greetings are, as you might expect:
1. happy new year!
2. best wishes for a happy new year.
3. may your new year start out joyful!
4. good fortune and success in the new year!
5. may the season's joy stay with you all year round!
6. may joy and happiness surround you today and always!
7. even though we're apart, you're in my heart this new year's season.
8. wishing you peace, joy and happiness throughout the coming year.
then they get more complicated:
1. may the warmest of wishes, happiest of thoughts and friendliest of greetings come to you and stay with you throughout the year.
2. wishing you a holiday season filled with joy, and all the happy things in life.
3. i was looking out the windows thinking about the person i care most about and the person that came to mind was you, so i want to wish you a happy new year.
4. another year has come to an end. and it's nice to have a friend like you to make my every day so great. thank you my dear friend.
5. when a greeting comes from afar you can't hear the wishes and can't see the smile, but you can sense the care that truly comes from the heart. happy new year.
6. everyone says the earth is such a huge place. so, with those billions and billions of people and all, i believe it's a miracle that i got to know you!
7. if i were in heaven, i'd write your name on every star for all to see just how much you mean to me.
8. remember that there is always someone thinking of you at new year, whether you get the message or not.
9. a special smile, a special face. a special someone i can't replace. a special hug, from me to you. a special friendship, i've found in you... happy new year, my dear friend.
in case you're using a mobile phone, there are short forms for certain words that can save time and put some cuteness in your message. for example, "xmas" for "christmas", "r" for "are", "u" for "you", "ny" for "new year", "c" for "see" and "4" for "four".

一、非謂語動詞
“非謂語動詞”可分為動詞不定式、動名詞和分詞.它在句子中的作用很多：除了不作謂語外,它可以充當(dāng)主語、賓語、表語、定語、狀語與復(fù)合賓語(主語補(bǔ)語或賓語補(bǔ)語).有些及物動詞后面接不帶to的不定式作復(fù)合賓語.這些動詞歸納如下：一感(feel).二聽(hear,listen to),三讓(have,1et, make),四看(see,watCh,notice,observe).再加上help somebody(to)do something和美國英語look at somebody do somthing.還有“二讓”屬特殊：get somebody to do something 與keep somebody doing.而有些及物動詞后面接動名詞(the -ing form)作賓語.這些動詞歸納為一句話：Papa C makes friends.這是由如下動詞的開頭字母組成：permit,advise, practise,avoid,consider,mind, allow,keep,enjoy,suggest, finish,risk,imagine,escape,need,delay,stand(忍受). 為了容易記住,也可以編成順口溜：“允許完成練習(xí),建議避免冒險,考慮延期逃跑,喜歡保持想象,需要反對忍受”.其相對應(yīng)的動詞依次是：permit/allow,finish,practise;
advise/suggest, avoid,risk： consider, delay, escape/miss; enjoy/appreciate, keep, imagine; need/want/require,mind. can't help/can’t stand.
二、復(fù)合句
1、學(xué)生最容易混淆的是定語從句與同位語從句的區(qū)別.
例如：A、The news that our team has won the match is true. (同位語從句)
B、The news that he told us surprised everybody here. (定語從句)
關(guān)鍵的區(qū)別在于連接或關(guān)系代詞that：有意義的是定語, 無意義的是同位.因為引導(dǎo)定語從句的that在從句中作主語或 賓語,而引導(dǎo)同位語從句的that只起到連接詞的作用.
2、接著容易混淆的是引導(dǎo)定語從句的關(guān)系代詞that與 which：that之前是不定(代詞)、序數(shù)(詞)、(形容詞)級：which之前是介詞短語與逗號(非限制性).
例如：A、All that we have to do is to practise every day.
B、The first lesson that I learned will never be forgotten.
C、I have lost my pen,which I like very much.
D、The house in front of which there is a garden is my home.
三、It的用法
1、It除了代替人和物以外,還可以作形式主語.而真正的主語(不定式、動名詞或從句)則放于謂語或表語之后.
例如：It is nor easy to finish the work in two days.
然而有少數(shù)表語之后接動名詞作真正的主語.這些表語是：無助(no help)、無用(no use)、沒好處(no good);工作(hard work)、費(fèi)時(a waste of time)、又危險(a danger).
例如：A、It is no use crying over spilt milk.
B、It is a waste of time waiting for him.
2、It還可以作形式賓語.通常下列動詞后面可接it作形式賓語：2f2tcjm(find,feel,think,take,consider,judge, make).
例如：A、He made it clear that he was not interested in this subject.
B、I think it no use arguing with him.
3、It用于強(qiáng)調(diào)句式.要強(qiáng)調(diào)句子的某一部分(主語、賓語、 狀語),可以把it當(dāng)作先行詞.這種句子的結(jié)構(gòu)是：It is(was)+ 被強(qiáng)調(diào)部分+that(who)+句子的其余部分.
例如：A、It iS Professor Lin who teaches us English—(強(qiáng)調(diào)主語)
B、It was in Shanghai that l saw the film.—(強(qiáng)調(diào)狀語)
C、It was in 1990 that I worked in the factory.(同上)
但要注意與定語從句的區(qū)別.
例如：D、It was 1990 when I worked in the factory.(定語從句)
在強(qiáng)調(diào)句式里,我們把強(qiáng)調(diào)結(jié)構(gòu)It is(was)…that除去,句子還很完整.如例句C.而例句D就不能.
四、倒裝結(jié)構(gòu)
學(xué)生容易混淆的是全部倒裝與部分倒裝.如何區(qū)分之,編個順口溜：副(adv.)介(prep.)提前全倒裝,其它句式部分倒;否定提前倒助動,讓步狀語倒表語;復(fù)合句式倒主句,不
倒裝的屬特殊.下面舉例說明：
A、Here comes the bus.(副詞提前,全倒裝)
B、Here he comes.(代詞作主語,不倒裝)
C、In front of the house lies a garden.(介詞短語提前,全倒裝)
D、Never shall I do this again.(否定詞提前,部分倒裝)
E、Young as he is ,he knows a lot.(讓步狀語從句,表語倒裝)
F、Only when he told me did I realize what trouble he was in.(only 修飾狀語,主句倒裝)
G、Only he can save the patient.(only修飾主語.不倒裝)
H、Not only will help be given to people,but also medical treatment will be provided.(否定詞提前,部分倒裝)
I、Not only he but also we like sports.(連接兩個主語,不倒裝)
五、虛擬語氣
虛擬語氣也是一個難點.所謂虛擬語氣是表示說話人的愿望、假設(shè)、猜測或建議,而不表示客觀存在的事實.它通過句子的謂語動詞的特殊形式來表示.現(xiàn)歸納如下：純假設(shè),用虛擬,動詞時態(tài)退一級：條件句,分主從,主句謂語前加would (should,could,might);表愿望,用虛擬,wish后面接賓語(從句)：現(xiàn)在過去與將來,動詞時態(tài)退一級：提建議,用虛擬,賓語(從句)動詞用(should)do：倆建議,三要求,再加堅持與命令(suggest,advise,demand,require,request,insist,order)：It is time和eoukd rather,后接叢句用虛擬：部分主語從句中, 謂語用虛擬結(jié)構(gòu) (It is necessry /important/natural/natural/strange/strange that……should do). 下面舉例說明：
A、If you came tomorrow,we would have the metting. (條件句虛擬)
B、Without air,there would be no living things.(同上)
C、We wish we had arrived there two hours earlier.(表示愿望虛擬)
D、He demanded that we (should)start right away.(表示建議虛擬)
E、It is(high)time that we left (should leave)now.(特殊從句虛擬)
F、I would rather you gave me the book.(同上)
G、It is necessary that we should clean the room everyday,(主語從句虛擬)
H、He speaks English so fluently as if he were English. (特殊從句虛擬)

虛擬語氣在一些特殊詞中的使用或含蓄條件句
1.wish后的賓語從句。
與現(xiàn)在愿望不一致，用主語十過去時，例如：
I wi。hIwere you.
與過去愿望不一致，用主語+had+過去分詞，例如：Iwish I had visited the White House whenI was in the States與將來愿望不一致，用主語+would (could)+原形。
2.It's time句型：當(dāng)lt's tine后用that從句時應(yīng)該為主i吾+should+動詞原形或主語十過去時，例如：It，s time thatyou went to school.或It's time that you should go to schooL
3- If only引起的感嘆句相當(dāng)于“How I wish+賓語從句”。
(l)If only he could come.他要能來就好了。
(2)If only I had known the answer.我要早知道答案就好了。
4.WOuld rather，as if(though)引導(dǎo)的從句也需使用虛擬語氣，表示過去的情況用過去完成時，表示現(xiàn)在與將來的情況用過去時，例如：
(l)I'd rather you posted the letter right away.
(2)She loves the children as if they were hers.
5.含蓄虛擬條件句含蓄條件句是指句中沒有明顯的虛擬條件句，而是利用其他手段來暗示存在虛擬條件。但是這類隱含式虛擬條件句往往都可以轉(zhuǎn)化為if引導(dǎo)的條件句。常用來表示含蓄虛擬條件的手段有：
(1)介詞或介詞短語。如but for，but that，without,in case of, under more favorable condition等。
(2)連詞。如so that, unless, in case, supposing,lest, provided(倘若……)，for fear that(唯恐)，in orderthat, on condition that, if only(要是……就好了)等。
注意：lest, for fear that和in case引起的從句中謂語動詞多用should+動詞原形，但也可以不用虛擬語氣，而用動詞的陳述語氣形式。例如：The foreign teacher spokeslowly in case we misunderstood him這位外籍教師說得很慢以免我們誤解。
(3)通過上下文及內(nèi)在含義，句中往往有but,otherwise, unfortunately等類似轉(zhuǎn)折詞。
without, but. but for, otherwise引起的短語或句子常暗含著含蓄條件。例如：
①Without you,1 would never know him
②But for your oooperation, we wouldn't have done it
③But that she was afraid, she would have said no. .
④i would be most glad to help you, butI am busy now.
⑤I would have come to the party yesterday, but ljwas working.
⑥I am busy now, otherwise l would do you the favor!
