⑸ 大蝦們 八年級英語的重點語法有哪些
1.一般過去時態.這一時態在七年級已經接觸過,八年級算復習吧.表示過去某一時間點或時間段發生的事情.謂語動詞分實義動詞和be動詞兩種.
(1)I studied Japenese for two years.
(2) I was a student one year ago,but now I am a teacher.
2.過去進行時態.結構:was/were +V-ing ,表示過去某一時間點或時間段正在進行的事情.
eg.I was sleeping when the phone rang.
3.一般將來時態.結構:will+V,表示將來某一時間將要發生的事情.
eg.I will go back home in three months.
4.現在完成進行時態.結構:have/has+been +Ving,表示某一行為從過去某一時間點開始,一直延續到現在,並有可能繼續進行下去.
eg.I have been teaching English in this scool for two years.
5.現在完成時態.結構:have/has +done(動詞過去分詞,需要記憶),表示一動作從過去開始,延續到現在,並且已經完成.強調這一事情對現在造成的影響.
eg.I have finished my homework.
基本上就這些了.你剛剛提到的過去式和現在進行時是七年級的語法點,八年級會予以鞏固並加大難度.
建議上課的時候注意聽老師講,重在理解,而後多背一些例句,並能進行應用.
英語是一個慢慢累積的過程,慢慢來.祝進步.

⑺ 初二英語下冊語法重點
下冊主要就是被動語態啦被動語態的主要用法
一.定義
語態是動詞的一種形式,它表示主語和謂語的關系。語態有兩種:主動語態和被動語態。如果主語是動作的執行者,或者是說動作是由主語完成的,要用主動語態;如果主語是動作的承受者,或者是說動作不是由主語而是由其他人完成的,則用被動語態。
■當不知道或沒有必要指出動作的執行者時,常用被動語態,這時往往不用by短語。
The front window in the classroom was broken yesterday. 昨天,教室的前窗被打破了。(不知誰打破的)
They have been poorly paid. 他們的工資太低。(沒必要指出工資是誰付的)
■突出或強調動作的承受者,如果需要說出動作的執行者,用by短語。
The time-table has been changed. 時間表已變動了。(要突出的是「時間」)
These books are written especially for children. 這些書是專門為孩子們寫的。(強調的是「」這些書)
■為了使語言得體或圓滑等不願意說出動作的執行者。如:
You are requested to make a speech at next meeting. 請您在下次會議上作個發言。
It is said that she is going to be married to a foreigner. 據說她要嫁給一個外國人。
■出於修辭的原因,或是說為了更好地安排句子。如:
The notion is especially opposed to by those who have invested much in the area. 這個提議特別遭到了那些在本地區投資很大的人的反對。(因those的定語太長了,若用它作主語,主語與謂語就相距太遠而顯得句子鬆散。)
8種常用時態的被動語態
由「助動詞be + 動詞的過去分詞」構成。助動詞be 有時態、人稱和數的變化。
(1) 一般現在時:am/is/are +過去分詞。如:
Rice is grown in south China. 華南種植水稻。
(2) 一般過去時:was/were+過去分詞。如:
The glass was broken yesterday. 這塊玻璃是昨天打爛的。
(3) 現在進行時:am/is/are being +過去分詞。如:
The project is being carried out. 這個計劃正在執行中。
(4) 過去進行時:was/were/being +過去分詞。如:
This road was being built this time last year. 這條路去年這個時候還在修建。
(5) 一般將來時:will be +過去分詞。如:
The cars will be sent abroad by sea. 這些汽車將由水路運往國外。
(6) 過去將來時:would be +過去分詞。如:
The manager said the project would be completed by the end of the year. 經理說這個工程在年底前將會完成。
(7) 現在完成時:have/has been +過去分詞。如:
This novel has been translated into several languages. 這本小說已被譯成了幾種語言。
(8) 過去完在時:had been +過去分詞。如:
When I got to the theatre, I found the tickets had already been sold out. 我到達劇院時,發現票已賣完了。

(8) 過去完在時:had been +過去分詞。如:

使用被動語態「六注意」
一要注意被動語態的不同時態
被動語態由「be+過去分詞」,其中的助動詞 be 根據情況可使用各種不同時態。如:
She is respected by everyone. 她受到大家的尊重。(一般現在時)
The book will be reprinted soon. 這本書很快會重印。(一般將來時)
The road is being repaired. 路正在修整。(現在進行時)
They have been given a warning. 他們受到警告。(現在完成時)
二要注意帶情態動詞的被動語態
該結構的基本形式為「情態動詞+be(或be的適當形式)+過去分詞」。這類結構非常有可能作為語境題出現在考卷中。如:
The rules must be obeyed. 這些規章制度必須遵守。
They shouldn』t have been told about it. 這事是不應當告訴他們的。
三要注意非謂語動詞的被動語態
1. 不定式一般式的被動語態。由「to be+過去分詞」構成。如:
She asked to be given some work to do. 她要求給她一些工作做。
2. 不定式完成式的被動語態。由「to have been+過去分詞」構成。如:
I should like to have been told the result earlier. 我本想讓人把結果早點告訴我的。
3. 現在分詞一般式的被動語態。由「being+過去分詞」構成。如:
I saw him being taken away. 我看見有人把他帶走了。
4. 現在分詞完成式的被動語態。由「having been+過去分詞」構成。如:
Having been invited to speak, I』ll start making preparations tomorrow. 因為邀請我去講話,我明天就得做准備。
5. 動名詞一般式的被動語態。由「being+過去分詞」構成。如:
He hates being made a fool of. 他討厭被別人愚弄。
6. 動名詞完成式的被動語態。由「having been+過去分詞」構成。如:
Jenny』s not having been trained as a dancer is her one regret. 傑妮沒受過舞蹈的專業訓練是她感到遺憾的事。
After having been instructed to drive out of town, I began to acquire confidence. 在接到把車開出城的指令後,我開始信心十足了。
註:過去分詞沒有被動式,因為它本身可以表示被動意義。如:
The door remained locked. 門仍然鎖著。
四要注意「get+過去分詞」構成的被動語態
英語被動語態通常由「助動詞be+過去分詞」構成,有時也可用「get+過去分詞」構成。如:
James got beaten last night. 詹姆斯昨晚被打了。
但總的說來,用get構成的被動語態不如用be構成的被動語態常見,尤其是在含有施動者的by短語時,用get構成被動語態更是少見。不過有時用be+過去分詞構成被動語態構成誤解時,人們可能會選get+過去分詞來避免這種誤解:
The window was broken. 窗戶破了(表狀態)。/ 窗戶被打破了(表動作)
The window got broken. 窗戶被打破了(表動作)
五要注意哪些動詞不用於被動語態
1. 不及物動詞沒有被動語態。因為不及物動詞沒有賓語,所以若將其用於被動語態則沒有主語,故不能用於被動語態。但是值得注意的是,有些英語中的不及物動詞,譯成漢語時卻可能是「及物」的,很容易出錯,這類動詞如:take place(發生),happen(發生),come about(發生),break out(爆發),appear(出現),disappear(消失),last(持續),arise(出現,發生)等:
Influenza usually breaks out in winter. 流感通常發生在冬季。
2. 英語中的靜態動詞(如have, lack, fit, hold, suit, resemble 等)通常不用於被動語態:
The young man lacks experience. 這個年輕人缺乏經驗。
英語不用被動語態幾種的情形
1.謂語為連系動詞時,不用被動語態。如:He looked fine. 他氣色好。The food tastes delicious. 這食物味道很好。
2. 謂語為不及物動詞(短語)時,不用被動語態。如:The war broke out in the end. 戰爭終於爆發了。
3. 賓語為不定式、動詞的-ing 形式或從句,表示主語的一些想法、愛好或願望時,一般不用被動語態。如:
He decided to go with us. 他決定跟我們一起去。4. 賓語是相互代詞、反身代詞、同源賓語等時,一般不用被動語態。如:
We should help each other. 我們應該相互幫助。He thinks of himself too much. 他對自己想得太多。
5. 賓語是處所、地點時,一般不用被動語態。如:
We will reach the station in two hours. 我們再過兩個小時就會到站了。
6. 謂語部分(動詞與賓語) 是一個不可分割的動詞短語時,一般不用被動語態。如:
The ship set sail this morning. 這艘輪船今天早晨起航了。
通常不用於被動語態的靜態動詞
那裡的人缺乏食物。正:People there lack food. 誤:Food is lacked by people there.
從形式上看,第2句是第1句的相應的被動形式,既然第1句為正句,那麼第2句從理論上說應該是成立的。而事實上第2句卻是個錯句。
在英語中,並不是所有的及物動詞都可以用於被動語態的,有些動詞(尤其是那些靜態動詞)盡管它們可以帶賓語,但卻不用於被動語態,這種動詞考生容易弄錯,其中主要的有:have,lack,fit,suit,cost,let,like等:
他有一台電腦。正:He has a computer.誤:A computer is had by him.
他當時正在洗澡。正:He was taking a bath. 誤:A bath was being had by him.
我的鞋不適合。正:My shoes don』t fit me. 誤:I am not fitted by my shoes.
這架鋼琴花了她6000美元。正:The piano cost her 6000 dollars.
六要注意兩類被動句型的相互轉換
英語中有一種主動句可以轉換成兩種被動句型,它們通常是一些表示客觀說明的句子。如:
People believed that she is honest. 大家相信她是誠實的。
It』s believed that she is honest. 大家相信她是誠實的。
She is believed to be honest. 大家相信她是誠實的。
比較上面兩類被動句型可以發現,一類是「it+be+過去分詞+that從句」,另一類則是「主語+be+過去分詞+不定式」(其中的「主語」為前一類句型中that從句中的主語),通常可用於這兩類被動句型的動詞有assume, believe, expect, fear, feel, know, presume, report, say, suppose, think, understand等,比較(同時注意其中時態和動詞形式的變化):
It』s known that he was a good singer. / He is known to have been a good singer. 大家知道他曾是位優秀的歌手。
表示「據說」的三類被動句型
