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.

Notes:
1. Don’t forget to use a comma (,) when the adverbial clause comes before the main clause.
当状语从句出现在主句之前时，不要忘记加逗号（,）。
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.
说话者 / 作者强调原因时用 because，强调结果时用 since，as 和 now that。
