Adverbial clauses
of reason
Read and think
How are the underlined parts formed
(1) Three boys were also unhappy because they got no parts to play but the job of helping out backstage with Shirley.
(2) Sam pulled a long face as he felt the same way.
(3) Since Ella always seemed self-important, Shirley had never liked her.
In each sentence above, the underlined part starts with a linking word (e.g. because, as, since) and introduces the reason for result of something. It answers the “why” “how” question. We therefore call this an “adverbial clause of reason”.
An adverbial clause of reason comes before after either
before or after the main clause.
Work out the rules
Tick (√) the one(s) you agree with.

An adverbial clause of reason starts with a linking word/phrase (e.g. subordinating conjunction) like because, since, as and now that, and comes before or after the main clause.
原因狀語從句通常由 because，since，as，now that 等連接詞 / 短語（如從屬連詞）引導。原因狀語從句可放在主句前，也可放在主句后。

Notes:
1. Don’t forget to use a comma (,) when the adverbial clause comes before the main clause.
當狀語從句出現在主句之前時，不要忘記加逗號（,）。
2. Because is used when the information focus of a speaker/writer is on the reason; since, as and now that are used when the focus is on the result.
說話者 / 作者強調原因時用 because，強調結果時用 since，as 和 now that。
