As的四種用法,八種語意- 如何正確使用As?

一個英文單字的詞性決定了這個單字要如何用,它在句子的位置會不一樣。有些單字同時具有兩種以上的詞性,有些單字甚至因為詞性不同,而有不同的意思,如果沒有注意到詞性跟語意的差別,在閱讀時,常會造成困惑,在寫作上,也會不知如何使用。as就是這樣的一個字。它不只自己本身詞性跟語意眾多,它也跟許多常見的動詞、形容詞、副詞等構成搭配詞與片語,可以說,它是英文最廣泛被使用的字之一。本文將詳細解說as的各種用法與句型。

As要如何用?詞性決定用法

as這個字有連接詞、副詞跟介系詞三種詞性,還可以當準關係代名詞。當它是連接詞時,它的語意可以是因為、當…時候、雖然、隨著、如同這五種意思,當他是介系詞時,語意是作為、以…的身份,當它是副詞時,語意則為一樣地…,修飾形容詞或副詞,常出現在原級比較的句型中。as 這個單字,因為不同詞性,用法差異非常大。

  • 從屬連接詞:因為、當…時候、隨著、雖然、如同
  • 副詞:一樣地…
  • 準關係代名詞:用法跟that很像,但是先行詞要有the same…或such…
  • 介系詞:作為、以…的身份

As作為從屬連接詞的五種語意跟句型

as的語意是因為時,用法跟because一樣,在很多情況下,兩個字可以互換。除此之外,as比because正式一點。

  1. As it’s a long journey, I packed snacks and drinks for the trip.

  4. As the store is closed, we’ll have to come back tomorrow.

as的語意是當…時,用法跟語意和when跟while相近,用於表示某事與另一件事同時發生。在這個語意下,有一個常見片語是just as,語意強調兩個動作或事件恰好同時發生(兩件事非常密切地同時發生)。下面舉例說明as跟just as的分別:
As she left, my phone rang.
當她離開的時候,我的電話響了(這句話不強調兩件事非常密切的同時發生)
Just as I was about to leave, my phone rang.
就在我要離開的時候,我的電話響了(這句話強調的是電話鈴聲恰好發生在即將離開的那一刻)

  8. Just as I was about to take a bite of my sandwich, the doorbell rang.

-將be動詞後面的名詞移到句首,要記得將不定冠詞要去掉,再將though去掉,在主詞he前面加上as
-Child as he is, he has a mature understanding of the world.雖然他是個孩子,但他對這個世界有著成熟的認識
