⑤ 初二英語有啥語法
想問一下你學的是哪個版本？
我學的是仁愛的，重點考的比較廣。我們初二上學期主要考
【情態動詞】如can may must need will shall would could should
【一般將來時】它的定義結構標志詞
【反身代詞】如myself yourself himself herself itself ourselves yourselves themselves
【一般過去時和過去進行時】同樣定義結構標志詞
【形容詞的比較級】如good well better / best bad ill worse worst等
【感嘆句】以what /how引導的感嘆句
還有一般的動詞搭配，如do to do doing 【基本】prefer...to be going to do 等，太多了，這需要積累。動詞搭配要死記，這是單選完型容易考的。
希望有幫助：）
⑥ 初二必會的英語語法有哪些
一、意義與構成
1. 意義：表示過去
1) 發生或已經完成的動作對現在造成影響或後果
2) 某一時間開始並一直持續到現在的動作或狀態
2. 基本構成：have/has+ done (過去分詞)

c. 一般疑問句：Have/Has+主語+ done (過去分詞)
d. 特殊疑問句：特殊疑問詞+have/has+主語+ done過去分詞
二、過去分詞
與動詞的過去式一樣,動詞的過去分詞有規則動詞過去分詞和不規則動詞過去分詞兩種.
1. 規則動詞：規則動詞的過去分詞的構成規則與規則動詞的過去式的構成規則相同
1) 一般動詞,在詞尾直接加「 ed 」
如：work—worked—worked; play—played—played; enjoy—enjoyed—enjoyed.
2) 以「e」結尾的動詞,只在詞尾加「d 」
如：dance—danced—danced; live—lived—lived; place—placed—placed.
3) 以「輔音字母 + y 」結尾的動詞,將 「y」 變為 「i」 ,再加「ed」
注意：母音字母+y結尾的動詞的過去分詞的變法參見一般動詞.
如：carry—carried—carried; hurry—hurried—hurried; cry—cried—cried
4) 重讀閉音節結尾,末尾只有一個輔音字母,先雙寫這個輔音字母,再加「ed」
如：plan—planned—planned; stop—stopped—stopped; drop—dropped—dropped
2. 不規則動詞
不規則動詞的過去分詞有5種形式：
A-A-A 如：cost—cost—cost; cut—cut—cut; hit—hit—hit
A-B-B 如：bring—brought—brought; build—built—built; catch—caught—caught;
keep—kept—kept; sell—sold—sold; smell—smelt—smelt;
learn—learnt—learnt; say—said—said; meet—met—met;

此類變化涉及到的動詞較多,需要同學們認真記憶.

A-B-A 如：come—came—come
不規則動詞的過去分詞變化規則多,但是還是有一定的規律所循,希望同學們多花心思,細心記下,這是使用完成時態的基礎.
三、用法
1. 現在完成時用來表示過去已發生過或完成的動作或狀態,但其結果卻和現在有聯系,也就是說,動
作或狀態發生在過去但它的影響現在還存在.
I have spent all of my money. 我花光了身上所有的錢.
(含義是：I don』t have any money now.)
Jane has laid the table. Jane已經把桌子擺好了.
(含義是：We can sit and have dinner.)
Michael has been ill. Michael病了.
(含義是：He can』t come to school.)
He has returned from abroad. 他已經從國外回來了.
(含義是：He』s at home now.)
2. 現在完成時可以用來表示發生在過去某一時刻的,持續到現在的情況,常與for（+時間段）,
since（+時間點）連用.
Mary has been ill for three days. Mary已經病了三天了.
I have lived here since 1998. 我從1998年起一直住在這.
I have been a teacher for 10 years. 我當老師已經10年了.
注意：點動詞（buy, die, join, finish等）不能直接與for, since 連用,需要改變動詞.
1) have代替buy
I have bought new car. 他買了輛新車.(含義：他自己有車,不用搭別人車等.)
I have had this bike for almost 7 years. 我買這輛自行車七年了.
2) 用keep或have代替borrow
He has kept the book for a long time. 他借這書好長時間了.
3) 用be in替代come to/ join/ move to等
How long have you been in America? 你來美國多久了?
4) 用be+副詞 替代start/ get up/ return to/go back to
The show has been on for half an hour. Hurry up!
演出已經開始了半個小時了.快點!

我起床已經一個小時了,但是我還是覺得很困.
He has been back to his hometown for a year, but he』s still missing the life in the
city.
他回到故鄉都一年了,但是他還是很懷念城市生活.
總之,後加時間的完成時表達中,都表達一個動作所延續的時間,而點動詞只表達那一動作,動作之後所處的狀態,應該用相應的狀態詞來表達,如come是「來」的意思,而來之後的日子都是「在…」因為不能用come表達,應該用be in…來表達,意為「一直處於…」.
3. 現在完成時的時間狀語
現在完成時屬於現在時范圍,故不能和過去的時間狀語連用.如：yesterday, last Sunday,
in1990, three years ago等.但是,在強調動作產生的後果和影響時,可以和一些表示不確定的時
間狀語連用.
如：I have finished my homework yesterday. (×)
I finished my homework yesterday. (√)
1)副詞already和yet
already一般用於肯定句中,yet一般用於否定句和疑問句中.
如：I』ve already slept for 12 hours but I』m still feeling tired.
我都睡了12個小時了可是我還是很累.
I haven』t finished working yet.
我還沒有完成工作.
Have you found your lost cat yet?
你找到你丟了的小貓了嗎?
2)ever和never
多用於否定或疑問句中,表示「曾經」或「從未」.
如：---Have you ever been to the Great Wall? 你曾經去過長城嗎?
---No, I haven』t. I have never been to the Great Wall. 沒有.我從未去過長城.
3)用表示到說話為止的過去時間狀語,如：just, before, up to now, the past few years等.
如：I have just finished my paper. 我才寫完我的論文.
I』ve dream about that before. 我以前夢到過那個情景.
Up to now, he has got 3 gold medals in the Olympic Games.
到現在為止,他已經在奧運會中取得了三塊金牌.
He has been there three times the last few days.
近幾年他去過那裡三次了.
4)用包括「現在」在內的時間狀語,如：now, today, this morning (month, year, term)等.
如：---Have you met him today?
---No, I haven't.
---今天你見過他嗎?---沒有.
How many times have you been there this year?
今年你去過那裡多少次?

總之，後加時間的完成時表達中，都表達一個動作所延續的時間，而點動詞只表達那一動作，動作之後所處的狀態，應該用相應的狀態詞來表達，如come是「來」的意思，而來之後的日子都是「在…」因為不能用come表達，應該用be in…來表達，意為「一直處於…」。
3. 現在完成時的時間狀語
現在完成時屬於現在時范圍，故不能和過去的時間狀語連用。如：yesterday, last Sunday,
in1990, three years ago等。但是，在強調動作產生的後果和影響時，可以和一些表示不確定的時
間狀語連用。
如：I have finished my homework yesterday. (×)
I finished my homework yesterday. (√)

2)ever和never
多用於否定或疑問句中，表示「曾經」或「從未」。
如：---Have you ever been to the Great Wall? 你曾經去過長城嗎？
---No, I haven』t. I have never been to the Great Wall. 沒有。我從未去過長城。
3)用表示到說話為止的過去時間狀語，如：just, before, up to now, the past few years等。
如：I have just finished my paper. 我才寫完我的論文。
I』ve dream about that before. 我以前夢到過那個情景。
