初二英語語法
語法是英語考試中的重中之重,所占分值也多。提高英語能力的方法是多讀多練多積累。小編在這里整理了初二英語語法供大家閱讀,希望能幫助到您。
初二英語語法
1) leave的用法
1.“l(fā)eave+地點”表示“離開某地”。例如:
When did you leave Shanghai?
你什么時候離開上海的?
2.“l(fā)eave for+地點”表示“動身去某地”。例如:
Next Friday, Alice is leaving for London.
下周五,愛麗斯要去倫敦了。
3.“l(fā)eave+地點+for+地點”表示“離開某地去某地”。例如:
Why are you leaving Shanghai for Beijing?
你為什么要離開上海去北京?
2) 情態(tài)動詞should“應(yīng)該”學(xué)會使用
should作為情態(tài)動詞用,常常表示意外、驚奇、不能理解等,有“竟會”的意思,例如:
How should I know? 我怎么知道?
Why should you be so late today? 你今天為什么來得這么晚?
should有時表示應(yīng)當(dāng)做或發(fā)生的事,例如:
We should help each other.我們應(yīng)當(dāng)互相幫助。
我們在使用時要注意以下幾點:
1. 用于表示“應(yīng)該”或“不應(yīng)該”的概念。此時常指長輩教導(dǎo)或責(zé)備晚輩。例如:
You should be here with clean hands. 你應(yīng)該把手洗干凈了再來。
2. 用于提出意見勸導(dǎo)別人。例如:
You should go to the doctor if you feel ill. 如果你感覺不舒服,你最好去看醫(yī)生。
3. 用于表示可能性。should的這一用法是考試中常常出現(xiàn)的考點之一。例如:
We should arrive by supper time. 我們在晚飯前就能到了。
She should be here any moment. 她隨時都可能來。
3) What...? 與 Which...?
1. what 與 which 都是疑問代詞,都可以指人或事物,但是what僅用來詢問職業(yè)。如:
What is your father? 你父親是干什么的? 該句相當(dāng)于:
What does your father do?
What is your father's job?
Which 指代的是特定范圍內(nèi)的某一個人。如:
---Which is Peter? 哪個是皮特?
---The boy behind Mary. 瑪麗背后的那個男孩。
2. What...?是泛指,所指的事物沒有范圍的限制;而 Which...?是特指,所指的事物有范圍的限制。如:
What color do you like best? (所有顏色)
你最喜愛什么顏色?
Which color do you like best, blue, green or yellow? (有特定的范圍)
你最喜愛哪一種顏色?
3. what 與 which 后都可以接單、復(fù)數(shù)名詞和不可數(shù)名詞。如:
Which pictures are from China?
哪些圖片來自中國?
4) 頻度副詞的位置
1.常見的頻度副詞有以下這些:
always(總是,一直)
usually(通常)
often(常常,經(jīng)常)
sometimes(有時候)
never(從不)
2.頻度副詞的位置:
a.放在連系動詞、助動詞或情態(tài)動詞后面。如:
David is often arrives late for school.
大衛(wèi)上學(xué)經(jīng)常遲到。
b.放在行為動詞前。如:
We usually go to school at 7:10 every day.
我們每天經(jīng)常在7:10去上學(xué)。
c.有些頻度副詞可放在句首或句尾,用來表示強調(diào)。如:
Sometimes I walk home, sometime I rides a bike.
有時我步行回家,有時我騎自行車。
3.never放在句首時,主語、謂語動詞要倒裝。如:
Never have I been there.
5) every day 與 everyday
1. every day 作狀語,譯為“每一天”。如:
We go to school at 7:10 every day.
我們每天7:10去上學(xué)。
I decide to read English every day.
我決定每天讀英語。
2. everyday 作定語,譯為“日常的”。
She watches everyday English on TV after dinner.
她晚飯后在電視上看日常英語。
What's your everyday activity?
你的日?;顒邮鞘裁?
6) 什么是助動詞
1.協(xié)助主要動詞構(gòu)成謂語動詞詞組的詞叫助動詞(Auxiliary Verb)。被協(xié)助的動詞稱作主要動詞(Main Verb)。
助動詞自身沒有詞義,不可單獨使用,例如:
He doesn't like English. 他不喜歡英語。
(doesn't是助動詞,無詞義;like是主要動詞,有詞義)
2.助動詞協(xié)助主要動詞完成以下功用,可以用來:
a. 表示時態(tài),例如:
He is singing. 他在唱歌。
He has got married. 他已結(jié)婚。
b. 表示語態(tài),例如:
He was sent to England. 他被派往英國。
c. 構(gòu)成疑問句,例如:
Do you like college life? 你喜歡大學(xué)生活嗎?
Did you study English before you came here?你來這兒之前學(xué)過英語嗎?
d. 與否定副詞not合用,構(gòu)成否定句,例如:
I don't like him. 我不喜歡他。
e. 加強語氣,例如:
Do come to the party tomorrow evening. 明天晚上一定來參加晚會。
He did know that. 他的確知道那件事。
3. 最常用的助動詞有:be, have, do, shall, will, should, would
7) forget doing/to do與remember doing/to do
1.forget to do 忘記要去做某事。 (未做)
forget doing 忘記做過某事。 (已做)
The light in the office is still on. He forgot to turn it off.
辦公室的燈還在亮著,它忘記關(guān)了。(沒有做關(guān)燈的動作)
He forgot turning the light off.
他忘記他已經(jīng)關(guān)了燈了。 ( 已做過關(guān)燈的動作)
Don't forget to come tomorrow.
別忘了明天來。 (to come動作未做)
典型例題---- The light in the office is still on. ---- Oh,I forgot___.
A. turning it off B. turn it off
C. to turn it off D. having turned it off
答案:C。由the light is still on 可知燈亮著,即關(guān)燈的動作沒有發(fā)生,因此用forget to do sth.而forget doing sth 表示燈已經(jīng)關(guān)上了,而自己忘記了這一事實。此處不符合題意。
2.remember to do 記得去做某事 (未做)
remember doing 記得做過某事 (已做)
Remember to go to the post office after school.
記著放學(xué)后去趟郵局。
Don't you remember seeing the man before?
你不記得以前見過那個人嗎?
8) It's for sb.和 It's of sb.
1.for sb. 常用于表示事物的特征特點,表示客觀形式的形容詞,如easy, hard, difficult, interesting, impossible等:
It's very hard for him to study two languages. 對他來說學(xué)兩門外語是很難的。
2.of sb 的句型一般用表示人物的性格,品德,表示主觀感情或態(tài)度的形容詞,如good, kind, nice, clever, foolish, right。
It's very nice of you to help me. 你來幫助我,你真是太好了。
3.for 與of 的辨別方法:
用介詞后面的代詞作主語,用介詞前邊的形容詞作表語,造個句子。如果道理上通順用of,不通則用for。如:
You are nice. (通順,所以應(yīng)用of)。
He is hard. (人是困難的,不通,因此應(yīng)用for。)
9) 對兩個句子的提問
新目標(biāo)英語在命題中有將對句子劃線提問這一題型取消的趨勢,現(xiàn)在采取的作法是對一個句子進(jìn)行自由提問。例如:
句子:The boy in blue has three pens.
提問:1.Who has three pens?
2.Which boy has three pens?
3.What does the boy in blue have?
4.How many pens does the boy in blue have?
很顯然,學(xué)生多了更多的回答角度,也體現(xiàn)了考試的靈活性。再如:
句子:He usually goes to the park with his friends at 8:00 on Sunday.
提問:1.Who usually goes to the park with his friends at 8:00 on Sunday?
2.Where does he usually go with his friends at 8:00 on Sunday?
3.What does he usually do with his friends at 8:00 on Sunday?
4.With whom does he usually go to the park at 8:00 on Sunday?
5.What time does he usually go to the park with his friends on Sunday?
6.When does he usually go to the park with his friends?
10) so、such與不定冠詞的使用
1.so與不定冠詞a、an連用,結(jié)構(gòu)為“so+形容詞+a/an+名詞”。如:
He is so funny a boy.
Jim has so big a house.
2.such與不定冠詞a、an連用,結(jié)構(gòu)為“such+a/an+形容詞+名詞”。如:
It is such a nice day.
That was such an interesting story.
11) 使用-ing分詞的幾種情況
1.在進(jìn)行時態(tài)中。如:
He is watching TV in the room.
They were dancing at nine o'clock last night.
2.在there be結(jié)構(gòu)中。如:
There is a boy swimming in the river.
3.在have fun/problems結(jié)構(gòu)中。如:

he, she, it
my friend, his teacher, our classroom, Tom, Mary's uncle
2.名詞有單數(shù)名詞和復(fù)數(shù)名詞。如:

但是,若在表示請邀請、請求的句子中,some可以不變。如:

18) 如何表達(dá)英語中的“穿、戴”?
英語中表示“穿、戴”的表達(dá)方法有好幾種,常見的有以下這些:

2、like 作介詞,可譯成“像......”。如:

A句指外貌相似,而D句指性格相似。
21) stop to do sth 與 stop doing sth
1. stop to do sth 意為“停下來去做某事”。如:
The students stop to listen to their teacher.
學(xué)生們停下來去聽他們老師講話。
2. stop doing sth 意為“停止做某事”。如:

He finishes his homework and goes on to study English.
他完成了作業(yè),接著繼續(xù)去念英語。
They went on playing games. 他們繼續(xù)玩游戲
初二英語學(xué)習(xí)技巧
首先要教會科學(xué)的學(xué)習(xí)方法,就是“三習(xí)”學(xué)習(xí)法。即:課前預(yù)先,課上學(xué)習(xí),課后復(fù)習(xí)。預(yù)先發(fā)現(xiàn)重點.難點和疑點。學(xué)習(xí)時認(rèn)真聽講.認(rèn)真思考.復(fù)習(xí)時要歸納分析知識點使之形成知識版塊,從而形成為自己頭腦中的知識的一部分。學(xué)好語音和單詞,用音形結(jié)合記憶法,拼讀規(guī)則記憶法,分類記憶法,歸納記憶法,搭配記憶法,聯(lián)想記憶法,卡片記憶法等。對話與課文要讀準(zhǔn)意群和句子。翻譯要準(zhǔn)確通順,然后要背誦。聽力要堅持每天抽時間讀,聽,說練習(xí),并且有針對性地做些練習(xí)鞏固。
關(guān)于語法,初二英語的語法點在初一的基礎(chǔ)上有所深入,隨著句型和詞匯的擴(kuò)展,語法似乎顯得更加復(fù)雜。分散開來好像更加繁雜瑣碎,半個學(xué)期下來好像突然出現(xiàn)很多個小點,記憶起來很麻煩。其實不然。初二的每一個知識點都是初一的稍加拓展,而且知識本身也是相互關(guān)聯(lián)的。☆比如人稱代詞,這時的重點已經(jīng)不是主格和賓格的區(qū)分,而是形容詞形物主代詞、名詞性無主代詞、反身代詞在情景對話以及寫作中的應(yīng)用。還會涉及到形容詞和副詞的比較級、高級以及辨析名詞的數(shù)、各種介詞、基數(shù)詞、序數(shù)詞☆存在句、祈使句☆比如一般現(xiàn)在時,這時的重點已經(jīng)不是表達(dá)習(xí)慣性動作,而是平率副詞的使用規(guī)則。還有現(xiàn)在進(jìn)行、過去進(jìn)行等等時態(tài)的綜合訓(xùn)練☆這時也開始深入了解引語的使用、賓語從句、條件狀語從句。其實它們都是我們以前就見過的,甚至很早就見過了,現(xiàn)在我們只是通過更加深入系統(tǒng)的學(xué)習(xí)使自己在面對這些題時更加從容地得分,提高學(xué)習(xí)效率。其實語法是得分的方法,學(xué)習(xí)語法就是學(xué)習(xí)得分的方法:比如你看到了某個標(biāo)志詞,你就知道用什么時態(tài);你認(rèn)識了某個句型,你就知道該填哪個關(guān)鍵詞。其實很快你就會知道語法比你想象得要簡單。
學(xué)習(xí)英語要腳踏實地,沒有捷徑,但死記硬背也不是好方法。要大聲朗讀,反復(fù)訓(xùn)練發(fā)音器官和耳朵,這樣既可以提高聽力,又可以改進(jìn)口語發(fā)音,還記了單詞。利用一些好的方法能夠讓你更好地學(xué)習(xí)英語。
本次整理就到這里啦,祝大家在考試中能金榜題名!
