2012屆中考英語重點(diǎn)語法總復(fù)習(xí)教案
廣州英語-上海牛津版-七年級下-重點(diǎn)語法
1. 反意疑問句
反意疑問句是由兩部分組成的，前一部分是對事物的陳述（即陳述句），后一部分是簡短的提問（即簡短疑問句），中間用逗號隔開。如果前一部分用肯定句，后一部分就用否定疑問句；如果前一部分用否定句，后一部分就用肯定疑問句。兩部分的人稱和時(shí)態(tài)要一致。其回答是用yes或no來表示。
肯定反意疑問句的回答和否定反意疑問句的回答翻譯成漢語是有區(qū)別的：
1）肯定反意疑問句回答時(shí)yes和no翻譯成漢語時(shí)是一致的：
例如："It’s new, isn’t it?" "Yes,it is." （“這是新的，對嗎？”“是，是新的�！保�
"It’s new, isn’t it?" "No,it isn't."（“這是新的，對嗎？”“不，不是新的�！保�
2）而否定反意疑問句回答時(shí)yes和no翻譯成漢語時(shí)是不一致的：
如："It isn't new, is it?" "Yes,it is." （“這不是新的，對嗎？”“不，是新的�！保�
"It isn't new, is it?" "No,it isn't."（“這不是新的，對嗎？”“是，不是新的�！保�
2. 現(xiàn)在進(jìn)行時(shí)
一、目前（甚至說話時(shí)）進(jìn)行的動(dòng)作。
二、目前階段正在進(jìn)行，而此刻不一定在進(jìn)行的動(dòng)作。
現(xiàn)在進(jìn)行時(shí)是由be (am / is / are)
+v.-ing (動(dòng)詞現(xiàn)在分詞)構(gòu)成。否定形式是：am not
/isn’t / aren’t + v.-ing;一般疑問句形式則是Am / Is /
Are+主語 + v.-ing？常和現(xiàn)在進(jìn)行時(shí)連用的時(shí)間狀
語有: now, at the moment, these years/ months / weeks / days等或者句中有l(wèi)isten, look，此外，我們還可以根據(jù)上下句來判斷是否用現(xiàn)在進(jìn)行時(shí)。
某些表示思想、感覺、所屬或狀態(tài)等靜態(tài)動(dòng)詞如believe, think, know, understand, love, like, see, hear, smell, taste, want, own 等，一般不用現(xiàn)在進(jìn)行時(shí)。
3. when, while和as的區(qū)別
①時(shí)間連詞while，as與when是同義詞，均可解為“當(dāng)……時(shí)候”，用來引導(dǎo)時(shí)間狀語從句。 when引導(dǎo)的狀語從句時(shí)態(tài)用一般過去時(shí)或一般現(xiàn)在時(shí)，而while后的狀語從句時(shí)態(tài)是進(jìn)行時(shí)，其次when和while在表示時(shí)間上，when往往指時(shí)間上的一點(diǎn)，而while指一段時(shí)間，while 另指“在……的同時(shí)”
Eg. The headmaster came into the classroom while he was talking loudly.
She began to learn English when she was five.
② as 有時(shí)可與when, while通用，但它著重指主句和從句中的動(dòng)作或事情同時(shí)發(fā)生，不是一前一后。
As we walked, we talked.
4. also, too, either 與 as well 的用法區(qū)別
1) too 和 as well 多用于口語中，語氣較輕，通常用于肯定句或疑問句，一般不用于否定句，且通常放在句末。
如：Are they coming, too [as well]?
注意：在 Me too; You too這類簡略答語中，通常不用 as well或also。
2) also 比 too 和 as well 正式，一般也不用于否定句，它在句中的位置通常是緊靠動(dòng)詞，即放在行為動(dòng)詞之前，特殊動(dòng)之后。有時(shí)為了強(qiáng)調(diào)也放在句末(但不常見)。
如：She is young and beautiful，and also rich.
說明：also 有時(shí)用于句首(其后通常有逗號)，相當(dāng)于連詞 and。
如：Also, his mother was dead.
3) either(也)通常只用于否定句，且要放在句末。
如：He hasn’t finished it, either.
5. 人稱代詞?
人稱代詞表示人稱范疇以及他們的相關(guān)變化形式。人稱代詞有三個(gè)人稱，每個(gè)人稱又分為單復(fù)數(shù)形式。人稱代詞的形式如下：
單數(shù)復(fù)數(shù)
格主格賓格主格賓格
第一人稱Imeweus
第二人稱youyouyouyou
第三人稱hehimtheythem
??shehertheythem
人稱代詞的位置
1）人稱代詞一般出現(xiàn)在它所指代的名詞之后.
e.g. Tom is a five-year-old boy. He likes reading and swimming. ( he指代Tom)
2）人稱代詞也可出現(xiàn)在它所指代的名詞的前面。
e.g. Though he didn't know it, Jack was in danger. 杰克還不知道，他已經(jīng)處于危險(xiǎn)之中了。（he 指代Jack）
人稱代詞的指代作用: 人稱代詞不僅可以指人，也可以指物。人稱代詞的人稱，數(shù)和性由其所指代的名詞決定，人稱代詞的格由其在句子中的地位來決定。作為主語就用主格，做賓語用賓格
6. 反身代詞
1） 列表
Iyouyoushehe
myselfyourselfyourselvesherselfhimself
wetheyitone
ourselvesthemselvesitselfoneself
2）做賓語
a. 有些動(dòng)詞需有反身代詞
absent, bathe, amuse, blame, dry, cut, enjoy, hurt, introduce, behave
We enjoyed ourselves very much last night. 我們昨晚玩得很開心。
Please help yourself to some fish. 請你隨便吃點(diǎn)魚。
b. 用于及物動(dòng)詞+賓語+介詞
take pride in, be annoyed with, help oneself to sth.
I could not dress (myself) up at that time. 那個(gè)時(shí)候我不能打扮我自己。
注：有些動(dòng)詞后不跟反身代詞， get up, sit-down, stand up, wake up等。
Please sit down. 請坐。
3） 作表語； 同位語
be oneself: I am not myself today. 我今天不舒服。
The thing itself is not important. 事情本身并不重要。
4） 在不強(qiáng)調(diào)的情況下，but, except, for 等介詞后賓語用反身代詞或人稱代詞賓格均可。如：
No one but myself (me) is hurt.
注意：
a. 反身代詞本身不能單獨(dú)作主語。
(錯(cuò)) Myself drove the car.
(對) I myself drove the car. 我自己開車。
b. 但在and, or, nor連接的并列主語中，第二個(gè)主語可用反身代詞，特別是myself 作主語。
Charles and myself saw it.
5）第二人稱作賓語，要用反身代詞。
You should be proud of yourself. 你應(yīng)為自己感到驕傲。
7. 情態(tài)動(dòng)詞
一、can的用法：
1. (表示能力、功能)能,會
The classroom can seat thirty students. 這教室能坐三十位學(xué)生。
June can drive now. 瓊現(xiàn)在會開車了。

What can it possibly be? 到底那是怎么一回事?
二、could的用法

（用于虛擬語氣，表示與事實(shí)相反的設(shè)想）能；可以；
（表示可能性）可能；
（用于婉轉(zhuǎn)語氣）能，可以
三、may的用法
1.表示請求和允許，意思是：可以
He may come if he likes. 如果他想來，可以來
2.表示祝愿，意思是：�！�，（但愿）。
May the friendship between our two peoples last forever. 祝兩國人民的友誼萬古長青。
3.表示推測，意思是：可能（會），或許（會）。

四、must的用法
1.表“必須”。
You must talk to them about their study.你必須同他們談?wù)勱P(guān)于他們學(xué)習(xí)的事。
2.在否定結(jié)構(gòu)中表不許。

3.表堅(jiān)定的建議。

4.表推測，暗含有很大的可能性，用在肯定句。
He must be ill. He looks so pale.他肯定是病了。他的臉色那么蒼白。
注意： may 暗含的可能性較小。must 暗含的可能性較大。否定的猜測用can't
The baby can't be ill. He is so active.那寶寶不大可能是病了。他那么活躍。
五、might的用法
might表示的可能性太小，沒有足夠的說服力去職責(zé)別人。
can, could 之間的區(qū)別，和 may,might 之間的區(qū)別在于，虛擬句和過去時(shí)態(tài)用后者，表示的可能性比原詞小，但大部分時(shí)候2者可以互換，不會產(chǎn)生歧義或者對表述造成干擾。
六、should的用法
1.should 作為助動(dòng)詞 shall 的過去式，可以在間接引語中與第一人稱主語搭配，表示過去將來時(shí)間。
2.should 作為情態(tài)動(dòng)詞，通常用來表示現(xiàn)在或?qū)淼呢?zé)任或義務(wù)，譯作“應(yīng)該”、“應(yīng)當(dāng)”，這時(shí)它可以和 ought to， be supposed to 互換使用。例如：
You should （= are supposed to ） complete your test in time.
你們應(yīng)該按時(shí)做完你們的實(shí)驗(yàn)。
3.should 作為情態(tài)動(dòng)詞，可以用在條件狀語從句中，表示語氣較強(qiáng)的假設(shè)，譯作“萬一”、“竟然”，這時(shí)也可將 should 置于從句之首，即將 should 放在主語前面，而省略從屬連詞 if.
If it should rain tomorrow， I wouldn't go. （= Should it rain tomorrow， I wouldn't go.）
萬一明天天下雨，我就不去了。
七、 would的用法
1.would是will的過去式，Would you like～？
表示請求、勸說，是很客氣的說法。
Would you like a cup of tea？ 您愿意喝杯茶嗎？
2.主語+would like to～
表示“想要……”的意思上，與…want to～意思一 樣，但用此句型較客氣。
I want to ask you a question.
3.最基本的虛擬語氣句型:
主句用would/ should/ could/ might +動(dòng)詞原形。
八. ought to的用法
ought to 是一個(gè)可以加上to 的情態(tài)動(dòng)詞其意思與should是一樣的,但是ought to 不能用于虛擬語氣中表示推測,而should可以
ought to與should意思接近，大多數(shù)情況下二者可以互換，但是should談的是自己的主觀看法，ought to則更多反映客觀情況，在談到法律、義務(wù)和規(guī)定時(shí)使用。
如： We should／ought to help each other and learn from each other in our work．
She is your mother, so you ought to support her．
We ought to go and see Mary tomorrow, but I don’t think we will．
8. 物主代詞
1）物主代詞既有表示所屬的作用又有指代作用，例如：
John had cut his finger; apparently there was a broken glass on his desk.
約翰割破了手指，顯而易見，他桌子上有個(gè)破玻璃杯。
物主代詞有形容詞性（my, your等）和名詞性（mine, yours等）兩種,形容詞性的物主代詞屬于限定詞。
名詞性的物主代詞在用法上相當(dāng)于省略了中心名詞的 --'s屬格結(jié)構(gòu)，例如：
Jack's cap 意為 The cap is Jack's.
His cap 意為 The cap is his.
2) 名詞性物主代詞的句法功能
a. 作主語，如：May I use your pen? Yours works better.我可以用一用你的鋼筆嗎？ 你的比我的好用。
b. 作賓語，如：I love my motherland as much as you love yours.我愛我的祖國就像你愛你的祖國一樣深。
c. 作介詞賓語，如：Your should interpret what I said in my sense of the word, not in yours.
你應(yīng)當(dāng)按我所用的詞義去解釋我說的話，而不能按你自己的意義去解釋。
d. 作主語補(bǔ)語，如：The life I have is yours. It's yours. It's yours. 我的生命屬于你，屬于你，屬于你。
9. 條件狀語從句
概念: 在復(fù)合句中，由從句表示的狀語叫做狀語從句。它可以用來修飾主語中的動(dòng)詞.形容詞.副詞等。根據(jù)它表達(dá)的意思，狀語從句可以分為時(shí)間狀語從句，地點(diǎn)狀語從句，條件狀語從句，比較狀語從句，目的狀語從句，結(jié)果狀語從句和讓步狀語從句等。由連接詞if或unless引導(dǎo)的狀語從句叫做條件狀語從句。（注意：在含有條件狀語從句的復(fù)合句中，如果主句是一般將來時(shí)態(tài)，從句要用一般現(xiàn)在時(shí)[主將從現(xiàn)原則])
經(jīng)典語句：If it dosen't rain tomorrow,we will go to the zoo.
If you open the door，i will come in.
條件狀語從句就是用以表示“在某種條件下,會……”, 常用if ,in case , on condition等詞來引導(dǎo)
連接詞主要有 if, unless, as/so long as, on condition that,provided,suppose,supposing 等。.
主句用一般將來時(shí)，if或unless引導(dǎo)的條件狀語從句用一般現(xiàn)在時(shí)。
固定搭配：unless = if...not.
e.g. Let's go out for a walk unless you are too tired.
If you are not too tired, let's go out for a walk.
if 引導(dǎo)的條件句有真實(shí)條件句和非真實(shí)條件句兩種:
真實(shí)條件句，如：If it rains tomorrow, we won’t go on a picnic.
非真實(shí)條件句是虛擬語氣的一種，表示與事實(shí)相反，如：If I were you, I would go with him.
so/as long as只要 由as (so) long as, in case引導(dǎo)。
So long as you’re happy, it doesn’t matter what you do.只要你高興，你做什么都沒有關(guān)系。
You may borrow my book as long as you keep it clean.只要你保持書的清潔，你就可以把我的書借去。
Take your umbrella in case it rains.帶著你的傘吧，以防下雨。
10. (a) few + 可數(shù)名詞, (a) little + 不可數(shù)名詞
a few / a little 為肯定含義，還有一點(diǎn)
few / little 為否定含義，沒有多少了。
He has a few friends. 他有幾個(gè)朋友。
He has few friends. 他幾乎沒有朋友。
We still have a little time. 我們還有點(diǎn)時(shí)間。
There is little time left.幾乎沒剩下什么時(shí)間了。
Although he 's wealthy，he spends___ on clothes.
A. little B. few C. a little D. a few
答案： A. spend所指的是錢，不可數(shù)，只能用little或 a little. 本句為although引導(dǎo)的讓步狀語從句，由句意知后句為否定含義，因此應(yīng)用little表示幾乎不。
固定搭配:
only a few (=few) not a few (=many) quite a few (=many)
many a (=many)
Many books were sold.
Many a book was sold. 賣出了許多書。
11. 現(xiàn)在完成時(shí)
意義: 補(bǔ)充過去發(fā)生并且已經(jīng)完成的動(dòng)作對現(xiàn)在造成影響或后果或過去某一時(shí)間開始并一直持續(xù)到現(xiàn)在的動(dòng)作或狀態(tài)

注意：
1.現(xiàn)在完成時(shí)不能單獨(dú)與準(zhǔn)確時(shí)間連用，(如表示過去的時(shí)間狀語）
如yesterday(morning、afternoon),last(morning、afternoon)等，除非與for, since連用.
2.現(xiàn)在完成時(shí)往往同表示不確定的過去時(shí)間狀語連用,如already（肯定）, yet（否定，疑問）, just, before, recently, still, lately等:
He has already obtained a scholarship.
I haven't seen much of him recently (lately).
We have seen that film before.
Have they found the missing child yet ?
3. 現(xiàn)在完成時(shí)常常與表示頻度的時(shí)間狀語連用, 如often, sometimes, ever, never, twice, on several occasion等:
Have you ever been to Beijing
I have never heard Bunny say anything against her.
I have used this pen only three times. It is still good.
George has met that gentleman on several occasions.
4. 現(xiàn)在完成時(shí)還往往可以同包括現(xiàn)在時(shí)間在內(nèi)的時(shí)間狀語連用, 如now, up to these few days/weeks/months/years, this morning/week/month/year, just, today, up to present, so far等:
Peter has written six papers so far.
Man has now learned to release energy from the nucleus of the atom.
There has been too much rain in San Francisco this year.
The friendly relations and cooperation between our two countries have been enhanced in the past few years.
Up to the present everything has been successful.
5. 現(xiàn)在完成時(shí)還可以用來表示過去的一個(gè)時(shí)間到現(xiàn)在這段時(shí)間內(nèi)重復(fù)發(fā)生的動(dòng)作.
We have had four texts this semester.
6.現(xiàn)在完成時(shí)的"完成用法"
現(xiàn)在完成時(shí)的"完成用法"指的是動(dòng)作發(fā)生在過去某一時(shí)刻并已結(jié)束，但該動(dòng)作對現(xiàn)在產(chǎn)生了影響，與現(xiàn)在情況具有因果關(guān)系。
例如：He has turned off the light.他已把燈關(guān)了。(動(dòng)作結(jié)束于過去，但說明的是現(xiàn)在的情況--燈現(xiàn)在不亮了。)
現(xiàn)在完成時(shí)"完成用法"的特點(diǎn)是動(dòng)作不延續(xù)，因此，該時(shí)態(tài)只能與表示不定的過去時(shí)間狀語(如：already，yet, before，recently等)、頻度時(shí)間狀語(如：never，ever，once等)、包括現(xiàn)在時(shí)刻在內(nèi)的時(shí)間狀語(如：this morning ／ month ／year...，today等)連用。
例如： Have you found your pen yet？你已找到你的鋼筆了嗎？
7.現(xiàn)在完成時(shí)的"未完成用法"
現(xiàn)在完成時(shí)的"未完成用法"指的是動(dòng)作開始于過去某一時(shí)刻，一直延續(xù)到現(xiàn)在，或可能還要繼續(xù)下去。
例如：He has lived here since 1978.自從1978年以來，他一直住在這兒。(動(dòng)作起始于1978年，一直住到現(xiàn)在，可能還要繼續(xù)住下去。)
I have been in the army for more than 5 years.我在部隊(duì)已經(jīng)呆了五年多了。(動(dòng)作開始于5年前，一直延續(xù)至今，有可能還要繼續(xù)下去。)
此種用法的句中常需一個(gè)表示一段時(shí)間的狀語(由since或for引導(dǎo))，或表示與現(xiàn)在時(shí)刻相連的時(shí)間狀語(如：up to now，so far)等。
例如：I have heard nothing from him up to now.到目前為止我沒有他的任何消息。
注意：(1)現(xiàn)在完成時(shí)的未完成用法只適用于延續(xù)性動(dòng)詞，不可用于終止性動(dòng)詞，即瞬間完成或延續(xù)時(shí)間很短的動(dòng)詞。如：come，go，arrive，leave，join，become，die等。
8.一段時(shí)間+has passed+since從句
9. 現(xiàn)在完成時(shí)常和短語 "up to now /till now", "so far" (意思是從過去某一確定的時(shí)間一直延續(xù)到現(xiàn)在.)
Up to/till now he's read many story books. 至今他已讀過好多故事書。
I've been to New York three times so far. 至今我已到紐約去過三次。
10 has gone (to),has been (to), has been (in) 的區(qū)別
gone:去了沒回
been to :去過
been in：呆了很久
11.不能與when連用
一般過去時(shí)和現(xiàn)在完成時(shí)
(1)、一般過去時(shí)的謂語動(dòng)詞用過去式，而現(xiàn)在完成時(shí)的謂語基本構(gòu)成是“助動(dòng)詞 have/ has + 過去分詞”。
(2) 、一般過去時(shí)通常與表示過去的時(shí)間狀語連用。如： yesterday, last week , two years ago ,just now ,in 2002 等；而現(xiàn)在完成時(shí)則常與 just ,already ,ever ,never 等副詞和 these days ,this week ,since ......, for ...... 等表示一段時(shí)間的狀語連用。
試比較以下幾組句子，有什么區(qū)別：
① A:Have you seen the film ?
B:Did you see the film ?
分析：你看過這部電影嗎？（ A ）句強(qiáng)調(diào)的是被問者對劇情是否了解；（ B ）句強(qiáng)調(diào)的是看這部電影的動(dòng)作是否發(fā)生過，并不強(qiáng)調(diào)是否知道其內(nèi)容。
② A:How has he done it ?
B:How did he do it ?
分析：他是怎么做的這件事？（ A ）句強(qiáng)調(diào)的是他做這件事的方式對現(xiàn)在產(chǎn)生了某種影響；（ B ）句單純的詢問做這件事的方式。
③ A:He has lived in Beijing for 8 years .
B:He lived in Beijing for 8 years .
分析：他在北京住了 8 年。（ A ）句講的是到目前為止他在北京住了 8 年，可能還會繼續(xù)在北京住下去。（ B ）句講的是他在北京住過 8 年，現(xiàn)在已經(jīng)不在北京了。
(2) 現(xiàn)在完成時(shí)強(qiáng)調(diào)過去發(fā)生的動(dòng)作對現(xiàn)在的影響和結(jié)果，而一般過去時(shí)與現(xiàn)在沒有聯(lián)系，只是說明某個(gè)動(dòng)作發(fā)生的時(shí)間是在過去。
比：I have washed the car. 我洗過了車。（看上去很漂亮）
I washed the car a moment ago. 我剛才洗過車了。
She has watered the flowers. 她已經(jīng)澆了花。（不需要再澆了）
She watered the flowers yesterday. 她昨天澆的花。
I have written the letter but I haven't posted it yet. 信我已經(jīng)寫好了，但還沒有寄出。
I wrote the letter last week and I posted it three days ago. 我上周寫的那封信，3天前寄出的。
3）現(xiàn)在完成時(shí)表示的動(dòng)作或狀態(tài)延續(xù)到現(xiàn)在并可能延續(xù)下去，而一般過去時(shí)則單純表示過去某段時(shí)間內(nèi)的經(jīng)歷。
比如：It has rained for five hours. 雨已經(jīng)下了5個(gè)小時(shí)了。
It rained for five hours yesterday. 昨天下了5個(gè)小時(shí)的雨。
He has waited for her for two hours. 他等她已經(jīng)兩個(gè)小時(shí)了。
He waited for her two hours and then went home. 他等她等了兩個(gè)小時(shí)，然后就回家了。
I have reviewed two lessons this morning. 今天上午我已經(jīng)復(fù)習(xí)了兩課。（說話時(shí)還在上午）
I reviewed two lessons this morning. 今天上午我復(fù)習(xí)了兩課。（說話時(shí)已是下午或晚上）
七年級英語重點(diǎn)句型總結(jié)
1．I think…意為“我認(rèn)為……”，是對某人或某事的看法或態(tài)度的一種句型。其否定式常用I don’t think…，如：I think he’s Mr Zhinag. (L17)I don’t think you are right.
2．give sth. to sb./ give sb. sth. 意為“把……給……”，動(dòng)詞give之后可接雙賓語，可用這兩種句型；若指物的賓語是人稱代詞時(shí)，則只能用give it/ them to sb. 如：
His parents give him a nice purse./His parents give a nice purse to him. Give it to Mr Hu.(L57)
3．take sb./ sth. to…意為“把……(送)帶到……”，后常接地點(diǎn)，也可接人。如：
Please take the new books to the classroom.
4．One…, the other…/One is…and one is…意為“一個(gè)是……；另一個(gè)是……”，必須是兩者中。如：One is red and one is grey.(L50)或 One is red,, the other is grey.
5．Let sb. do sth. 意為“讓某人做某事”，人后應(yīng)用不帶to的動(dòng)詞不定式，其否定式為Don’t let sb，do sth.，或Let sb. not do sth. 另外，Let’s 與Let us的含義不完全相同， 前者包括聽者在內(nèi)，后者不包括聽者在內(nèi)，如：Let’s go for a walk./Let us try once more, please.
6．help sb. (to) do sth./help sb. with sth.意為“幫助某人做某事”，前者用不定式作賓補(bǔ)，后者用介詞短語作賓補(bǔ)，二者可以互換。如：
Let me help you find it.(L42)/Let me help you with it.
7．What about…？/How about…？意為“……怎么樣？”是用來詢問或征求對方的觀點(diǎn)、意見、看法等。about為介詞，其后須接名詞、代詞或V-ing等形式。如：
What/How playing chess?
8．It’s time to do…/ It’s time for sth. 意為“該做……的時(shí)間了”，其中to后須接原形動(dòng)詞，for后可接名詞或V-ing形式。如：
It’s time to have supper. =It’s time for supper.
9．like to do sth./like doing sth.意為“喜歡做某事”，如：
Li Lei and his friends like to play in the tree house. (L 43)
前一種句型側(cè)重具體的一次性的動(dòng)作；后一種句型側(cè)重習(xí)慣性的動(dòng)作，試比較：
Tom likes swimming, but doesn’t like to swim this afternoon.
10．a(chǎn)sk sb.(not) to do sth. 意為“讓某人(不要)做某事”，其中ask sb.后應(yīng)接動(dòng)詞不定式，如：
Ask your friends to guess what is in it. (L44)
11．show sb. sth. / show sth. to do. 意為“把某物給某人看”，該句型的用法同前面第2點(diǎn)。如：
Show your friend your family photo.（L36）/Show your family photo to your friend.
12．introduce sb. to sb. 意為“把某人介紹給另一人”；introduce to sb.則是“向某人作介紹”。如：
Introduce your family to her.
語法易錯(cuò)點(diǎn)歸納總結(jié)
[第一類] 名詞類
1. 這些女老師們在干什么？
[誤] What are the woman teachers doing？
[正] What are the women teachers doing？
[析] 在英語中，當(dāng)一名詞作定語修飾另一名詞（單或復(fù)數(shù)形式）時(shí)，作定語的名詞一般要用其單數(shù)形式；但當(dāng)man，woman作定語修飾可數(shù)名詞復(fù)數(shù)形式時(shí)，要用其復(fù)數(shù)形式men，women.
2. 房間里有多少人？
[誤] How many peoples are there in the room？
[正] How many people are there in the room？
[析] people作“人、人們”解時(shí)，是個(gè)集合名詞，其單復(fù)數(shù)同形。
3. 我想為我兒子買兩瓶牛奶。
[誤] I want to buy two bottle of milk for my son.
[正] I want to buy two bottles of milk for my son.
[析] 表示不可數(shù)名詞的數(shù)量時(shí)，常用“a / an或數(shù)詞 +表量的可數(shù)名詞 + of + 不可數(shù)名詞”這一結(jié)構(gòu)， 其中當(dāng)數(shù)詞大于1時(shí)，表量的可數(shù)名詞要用其復(fù)數(shù)形式。
[第二類] 動(dòng)詞類
4. 你妹妹通常什么時(shí)候去上學(xué)？
[誤] What time does your sister usually goes to school？
[正] What time does your sister usually go to school？
[析] 借助助動(dòng)詞do（或does）構(gòu)成疑問句或否定句時(shí)，句中的謂語動(dòng)詞用其原形。
5. 琳達(dá)晚上經(jīng)常做作業(yè)，但今晚她在看電視。
[誤] Linda often do her homework in the evening，but this evening she watching TV.
[正] Linda often does her homework in the evening，but this evening she is watching TV.
[析] 在初一英語學(xué)習(xí)階段，我們接觸到了兩種主要時(shí)態(tài)：一般現(xiàn)在時(shí)和現(xiàn)在進(jìn)行時(shí)。一般現(xiàn)在時(shí)表示經(jīng)常的或習(xí)慣性的動(dòng)作，常和often，usually，sometimes 等時(shí)間狀語連用。在一般現(xiàn)在時(shí)的句子中，若主語是第三人稱單數(shù)，謂語動(dòng)詞要用其第三人稱單數(shù)形式�，F(xiàn)在進(jìn)行時(shí)表示現(xiàn)階段正在進(jìn)行或發(fā)生的動(dòng)作，現(xiàn)在進(jìn)行時(shí)由be（am / is / are） + ving形式構(gòu)成。
6 這雙鞋是紅色的。
[誤] This pair of shoes are red.
[正] This pair of shoes is red.
[析] 在shoes，trousers，gloves，glasses等表示成雙成對的衣物或工具名詞前用pair（表計(jì)量）修飾時(shí)，謂語動(dòng)詞的形式由pair的單復(fù)數(shù)形式來決定。
[第三類] 代詞類
7. 這張票是她的，不是我的。
[誤] This is hers ticket. It’s not my.
[正] This is her ticket. It’s not mine.
[析] 物主代詞有形容詞性物主代詞和名詞性物主代詞之分。形容詞性物主代詞之后一定要接名詞，而名詞性物主代詞之后不需接任何詞。
8. 吳老師教我們英語。
[誤] Miss Wu teaches our English.
[正] Miss Wu teaches us English.
[析] teach sb. sth.中的sb.作teach的賓語，因此當(dāng)sb.為人稱代詞時(shí)要用其賓格形式。
[第四類] 介詞類
9. 你能找到這個(gè)問題的答案嗎？
[誤] Can you find the answer of this question？
[正] Can you find the answer to this question？
[析] 英語中用“the answer to …”表示“……的答案”。類似結(jié)構(gòu)還有the key to the door，the way to the zoo
10. 格林先生星期六上午來這里。
[誤] Mr Green will come here in Sunday evening.
[正] Mr Green will come here on Sunday evening.
[析] 表示在上午、下午等時(shí)，介詞要用in；而表示在具體的某天上午、下午時(shí)，介詞要用on.

[誤] That little girl on a red skirt is our teacher’s daughter.

[第五類] 副詞類
12. 莉莉，你為什么不回家呢？
[誤] Lily，why don’t you go to home？
[正] Lily，why don’t you go home？

[第六類] 連詞類
13. 我喜歡語文和英語，但我不喜歡體育和歷史。
[誤] I like Chinese and English，but I don’t like P.E.and history.
[正] I like Chinese and English，but I don’t like P.E.or history.
[析] 在肯定句中并列成分之間用and來連接；而在否定句中，并列成分之間的連接需用or。
[第七類] 冠詞類
14. 乘飛機(jī)去北京花了史密斯一家人一個(gè)小時(shí)。
[誤] It takes Smiths a hour to go to Beijing by a plane.
[正] It takes the Smiths an hour to go to Beijing by plane.
[析] 1．表示“……一家人”用結(jié)構(gòu)“the + 姓氏復(fù)數(shù)”；
2．our 一詞的第一個(gè)字母不發(fā)音，它是以元音音素開頭的，所以“一小時(shí)”要用 an hour；
3．用介詞by表示“乘坐”某種交通工具時(shí)，交通工具名詞前不加任何冠詞。
[第八類] 句法類
15. ??你不是學(xué)生嗎？ ??不，我是學(xué)生。
[誤] ??Aren’t you a student？ ??No， I am.
[正] ??Aren’t you a student？ ??Yes， I am.
[析] 對否定疑問句的回答是用Yes還是用No，這取決于實(shí)際情況：如果事實(shí)是肯定的，就用Yes表“不”；如果事實(shí)是否定的，就用No表“是的”。
