【语法专项】

语法考点梳理：原因状语从句

1.引导词：原因状语从句通常由because,since,as引导，用来表示原因。

Hedidn’tcometoschoolbecausehewasill.

Asitisraining,weshallnotgothezoo.

Sinceyoucan’tanswerthequestion,I’llasksomeoneelse.

2.区分

①because表示直接原因，语气最强。because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because

【注意】

▲because和so不能同用在一个句子里。

▲because与becauseof的区别:

because后只能接句子，而becauseof后面只能接名词或名词短语，不能跟句子。

Becauseofthebadweather,weputoffthesportsmeeting.

Becauseitrainedyesterday,weputoffthesportsmeeting.

②as和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从句多放在句首。

Sincehehadnomusicalinstrumentsthen,hemademusicwithcommonobjectslikestonesandpaper.

Ashelikesthesoundsofnature,Tanusesthemalotinhismusic.

【拓展】

since用于现在完成时,表示“自从”
