☆詞語比較☆

1. because, since, as, for, now that

  它們都可以被用來引導原因狀語從句，其中

  (1) because 語氣最強，一般指事情發(fā)生的直接原因，

  回答提問，一般放在主句之后。

  Because he was ill, he was late for school.

  他生病了，所以遲到了。

  We must stay at home because it rained.

  (2) since 較弱，指雙方都明確的原因或眾所周知的原

  因，澤為“既然”，側(cè)重主句，從句表示顯然的或已知

  的理由。

  Since you don't like it, I'll put it away.

  既然你不喜歡，我就把它放在一邊。

  (3) as “由于，鑒于”，指客觀事實，常與since互換使

  用。

  As there was no answer, I wrote again.

  鑒于沒回復，我又寫了一封信。

  (4) for 是并列連詞，不說明直接原因而是對某種情

  況加以推斷，其引導的分句前常有逗號。

  He must be ill, for he is absent today.

  他…定是生病了，因為他今天沒來。

  (5) now that 用來說明一種新情況，然后加以推論。

  Now that you are ready, we'll start at once.

  既然你已經(jīng)準備好了，我們馬上開始。
