Ba chữ này đều có nghĩa vì, bởi vì nhưng cách dùng khác nhau. Ví dụ:  a) Because           - Because he was sleepy, he went to bed. – He went to bed because he was sleepy. Mệnh đề phụ có chữ because có thể đứng trước hoặc sau mệnh đề chính. Tuy nhiên phải chú ý nếu mệnh đề phụ đi trước phải có dấu phảy (,) ngăn cách nó với mênh đề chính            b) As           - As  she was free, she came to see me.             Vì cô ấy rảnh rỗi, cô ấy đến thăm tôi.           c) Since           - Since he doesn’t like music, he never goes to the concert              Vì anh ấy  không thích nhạc,  anh ấy không bao giờ đi xem hoà nhạc. Mệnh đề since  và as luôn đứng trước mệnh đề chính.           b) So/ As Long As           - As long as  ( So long as) you’re not busy. Can you help me ?             Vì bạn không bận rộn, bạn có thể giúp tôi ?    + Ngoài các liên từ phụ thuộc ( Subordinating Conjuctions) như Because, Since, As, As long as, ... chúng ta còn một liên từ kết hợp ( Co-ordinating conjuctions) FOR chỉ lý do.           * Liên từ kết hợp là liên từ nối hai mệnh đề độc lập (independent clauses) và không dùng ở đầu câu. Ví dụ:   - I phoned her, for I wanted to tell her about her exam.           Tôi gọi điện cho cô ấy vì tôi muốn nói với cô ấy về kỳ thi của cô ấy.   + Mệnh đề chỉ lý do còn có thể đổi ra cụm từ chỉ lý do ( phrases of reason) với because of hoặc due to. Ví dụ:           - Because  the weather was cold, we stayed home.           → Because of  the cold weather, we stayed home.           → Due to the cold  weather, we stayed home.             Vì thời tiết lạnh, chúng tôi ở nhà. Because và Because of  Because và Because of  đều có nghĩa là bởi  vì nhưng chúng được dùng với cẩu trúc khác nhau.  a ) Because là một liên từ (Conjunction), theo sau nó là một mệnh đề (Clause). Ví dụ: - Because the traffic was heavy, we were late for the meeting.                      S            V    Vì xe cộ đông đúc, chúng tôi đến buổi họp trễ. b) Because of là nhóm giới từ ( Prepositional phrase), theo sau nó là một cụm danh từ ( noun phrase) Ví dụ: - Because of  the heavy traffic, we were late for the meeting.
