一年級學(xué)生學(xué)習(xí)英語應(yīng)該記住的語法知識

字號:


    學(xué)英語,語法就好比你打算盤的能力,如果語法一塌糊涂,那么一本書你學(xué)的又慢又吃力,文章看的一知半解的,更別談寫作了。如果你語法精熟,那么一本書也是噼里啪啦的三下五除二就看完看透了,更不不會有語法障礙,無非生詞多點而已。以下是整理的相關(guān)資料,希望對您有所幫助!
    【篇一】   一般現(xiàn)在時
            一般現(xiàn)在時主要用于:
    1 、表示經(jīng)常性或習(xí)慣性動作。
    e.g. It seldom snows here.
    2 、表示現(xiàn)在的特征或狀態(tài)。
    e.g. He is always ready to help others.
    3 、普遍真理。
    e.g. Action speaks louder than words.
    4 、劇情圖片介紹,背景說明,動作解說。
    e.g. (Tom enters the room_and_sits at the table)
    Doctor : What`s your trouble, young man?
    Tom : I`ve caught a cold, doctor.
    5 、時間、條件、讓步、方式狀語從句表將要發(fā)生的動作時。
    e.g. Tomorrow we shall go for an outing unless it rains.
    與這種時態(tài)連用的時間狀語常有:
    always, often, never, seldom, usually, once, a week, now 等。

    
    

    【篇二】   一般過去時
           一般過去時主要用于:
    1 、表示過去某個時間發(fā)生的動作或情況(包括習(xí)慣性的動作或狀態(tài))
    e.g. When did you read the novel?
    She often came to help us in those days.
    2 、談到過去的情況時
    e.g. I didn`t know you were so busy.
    3 、談到已死人的情況時
    e.g. Lei Feng was a great communist fighter.
    與這個時態(tài)連用的時間狀語常有:
    yesterday, last night, the other day, two months ago, in 1985, then, just now,
    when, after, as soon as 引導(dǎo)的時間狀語從句,表示主句動作開始的時間。

    
    

    【篇三】    一般將來時
           一般將來時主要用于:
    表示將要發(fā)生的動作或情況
    e.g. Tom will have a bike of his own.
    與這個時態(tài)連用的時間狀語常用:
    tonight, tomorrow, the day after tomorrow, next week, in three hours, two days later 等。
    一般將來時態(tài)與其它結(jié)構(gòu)表將來情況的區(qū)別:
    一般將來時態(tài) :主要從時間的角度表將要發(fā)生的動作或情況。
    be going to 結(jié)構(gòu) :①表(主觀上)打算或準(zhǔn)備做某事時。 ②表有發(fā)生某事的預(yù)兆時。
    e.g. They are going to have a competition with us in studies. It is going to rain.
    據(jù)以上區(qū)別,故下面一句是錯的:
    I am going to be eighteen years old next year.
    應(yīng)改為: I shall be eighteen years old next year.
    be about to do sth 結(jié)構(gòu) :意為"剛要做某事"、"馬上要做某事"強調(diào)時間之緊迫性。
    e.g. We are about to discuss this problem.

    
    

    【篇四】   過去進行時
            過去進行時主要用于:
    表示過去某個時刻或階段正在進行的動作。
    e.g. At that time she was working in a PLA unit.

    
 那時她在解放軍某部工作。
    What were you doing this time yesterday?
    與這個時態(tài)連用的時間狀語常用:
    at nine o`clock, this time last night, these days, at that time 等。
    用 when 引導(dǎo)的時間狀語從句表示主句的動作正在進行的時間。
    e.g. When he came in, I was reading a newspaper.
    注:
    1 、 while 引導(dǎo)時間狀語從句敘述過去的動作時,從句常用過去進行時。
    e.g. I read a magazine while I was waiting for the bus.
    2 、 when 用作并列連詞,意為"這時",連接兩分句時,第一句多用過去進行時。
    e.g. I was reading a newspaper when he came in.
    一般過去時與過去進行時的區(qū)別:
    一般過去時:強調(diào)過去某一時間開始或完成的動作。
    過去進行時:強調(diào)過去某一時間正在進行的動作。
    試區(qū)別下面兩句: We were building a reservoir last winter.
    去年冬天我們在修建一座水庫。(可能尚未建成) We built a reservoir last winter.
    去年冬天我們修建了一座水庫。(已經(jīng)建成)

    now, these days, recently, this week 等。

    
    

    【篇六】   過去完成時
      1 、過去完成時是一個相對時態(tài),表示過去的過去,只有在兩個過去發(fā)生的動作相比較時才可顯示出來。
    e.g. As soon as we got to the station, the train had left.
    注:主從句表達(dá)的動作緊接時,即兩動作發(fā)生的時間沒有明顯時間上的懸殊或空檔時,主從句都可用一般過去時。
    e.g. Where did your brother study before he joined the army?
    2 、過去完成時可表示截止過去某一時間動作的總或動作的結(jié)束。
    e.g. By the end of last month. We had reviewed four books
