語法真簡單:從句(4)

什麼是副詞從句?(狀語從句)

副詞從句,顧名思義,就是那個起到副詞作用的從句,由主語和動詞組成。

在每個副詞從句的開頭,都有一個從屬連詞。

包括: after, although, because, and if 。


副詞從句(狀語從句)有什麼用?

句子中使用副詞從句,以向您的內容添加相關的描述性信息。

副詞從句的靈活性很強,可以在句子的不同部分使用。

例如,可以根據需要將它們放置在句子的開頭,中間或結尾。


副詞從句(狀語從句)位於句子起始:

副詞從句謂語句子起始的時候,一般後面會跟隨逗號,把副詞從句和後面的句子隔離。

  • Whether you like it or not, you have to attend the afternoon lessons.
  • Unless
    you apologize, you will be punished.
  • Unless you put more effort into your studies, you will not excel.

  • 副詞從句(狀語從句)位於句子中間:

    此時會有逗號將句子中間的副詞從句分開。 因為這是一種不同尋常的表達,最先想要表達的意思被中間的副詞從句隔斷了。

    下面是一個示例:

  • Dogs, although they bark, they cannot scare visitors.
  • James, although he is good at mathematics, he cannot score everything.
  • Chocolate, due to
    its low melting point, can never be used to bake.

  • 副詞從句(狀語從句)位於句子結尾:

    副詞從句放在句子末尾時,不需要任何其他標點符號。

    例如:

  • You need to keep on practicing the song until you get it right.
  • Give us a call when you get past Melbourne.
  • The day so was long because we were completely idle.
  • You need to remain calm even if something does not go as planned.
  • I won’t let you watch the video clip even though you are 18 years and above.
  • I never knew how good life was until I met you.

  • 副詞從句(狀語從句)的類型

    如果不確定某個從句是否為副詞從句,請檢查主語和動詞。 如果它由一個動詞和一個主語組成,並且確實回答了when, where, how的問題,那麼它就是一個副詞從句。

    您應該永遠記住正確使用副詞從句,因為它們會增加描述性信息,從而使您的文字更加具有詳實。


    狀語從句分為以下幾類:

    • 地點狀語
    • 時間狀語
    • 原因狀語
    • 目的狀語
    • 條件狀語


    地點狀語從句:

    地點狀語從句表示地點、 方位, 這類從句通常由where、wherever等引導。地點狀語從句可置於句首、句中或句尾。

    • Where there is a party, there is enjoyment.
    • We went home, where we had dinner. 此句是where引導的"非限制性"定語從句,這裡"where"= at home(先行詞是home)從句還原" we had dinner at home"全句譯:我們回到家,在家裡吃了頓飯.
    • I walk into the canteen where students are eating. 此句也是where 引導的定語從句,與上句不同之處在於此句是一個"限制性"定語從句.全句譯:我走進了這個同學們都在吃飯的食堂。(限定說明了是一個什麼樣的食堂)
    • Go back where you came from.(where引導地點狀語從句)


    時間狀語從句:

    用表示時間的連詞連接一個句子作狀語,這樣的主從複合句就是時間狀語從句。連接時間狀語從句的連接詞有:when, before, after, while, as soon as, until, since...... 這裡要注意一點的是,如果主句是一般將來時,從句只能用一般現在時表示將來意義。

    • When the referee brews the final whistle, all the players left the pitch.
    • After the exams are done, we will all leave the school compound.
    • When you think you know nothing, then you begin to know something.當你以為自己一無所知的時候,你就是在開始知道一些事物了。
    • Our headmaster laughed as she spoke.(我們的校長邊談邊笑。)
    • While my wife was reading the newspaper, I was watching TV. (was reading是延續性的動詞,was reading和was watching同時發生) 。
    • It will be four days before they come back. 他們要過四天才能回來。
    • I have been in Beijing since you left. 自從你離開以來,我一直在北京了。


    原因狀語從句:

    原因狀語從句指在句中用來說明主句原因的從句。引導原因狀語從句的從屬連詞有because(因為), as(由於), since(既然), now(that)(既然), when(既然), seeing (that) (由於,鑑於), considering (that)(考慮到), given (that) (考慮到),for(為)等。

      you had better help me with my mathematics.


    目的狀語從句:

    目的狀語從句:從句部分是用以補充說明主句中謂語動詞發生的目的的狀語從句。

    表示目的狀語的從句可以由that, so that, in order that, lest, for fear that, in case等詞引導;

    目的狀語從句的謂語常含有may, might, can, could, should, will, would等情態動詞。

    • You must speak louder so that /in order that you can be heard by all.
    • He wrote the name down for fear that(lest) he should forget it.

    • He eats a balanced diet every day to stay healthy.
    • He drinks two glasses of water after every day because the doctor has advised him to do so.
    • Say it louder (so) that everyone can hear you.
    <code>【注意】in order that與in order to的區別: 

    in order that+從句
    in order to+動詞原形 ( in order to後面加的那個不叫目的狀語從句,叫目的狀語)

    in order to 為了,後接動詞原形,做目的狀語。
    i get up early in order to catch the early bus.

    in order that 為了,後接從句,做目的狀語。
    i get up early in order that i can catch the early bus./<code>


    條件狀語從句:

    由引導詞if或unless引導的狀語從句叫做條件狀語從句。在英文中,條件是指某一件事情實現之後(狀語從句中的動作),其它事情(主句中的動作)才能發生,通常譯作“假如”。

    注意:在含有條件狀語從句的複合句中,表示將來時態,主句是一般將來時態,祈使句或情態動詞,從句要用現在時態,[主將從現原則](主將從現,將並非指將來時,還指表示將來含義的,跟著if後的那句話是從句。

  • <code>但有些句子,雖沒有含條件關係的連詞,卻也隱含著條件關係,

    如:but for若非,要不是
    But for the rain,we should have a pleasant journey.
    要不是下雨,我們的旅行肯定會很愉快。

    But for your help,we should not have finished in time.
