2023年初中英语：原因状语从句

定义

常见连接词

dont give up on something justbecauseyou think you cant do it.

--- chanda kochhar, ceo of icici

cherish your visions and your dreams,asthey are the children of your soul, the blueprints of your ultimate achievements.

--- napolen hill, motivational writer

sincetime is not a person we can overtake when he is gone, let us honor him with mirth and cheerfulness of heart while he is passing.

--- johann wolfgang von goethe, writer

复合句中，用来表示主句动作发生原因的从句叫做原因状语从句;他们的位置相对灵活，可以在句首，句中或句尾。

because 表示直接原因，直接最强 (回答why)

why did not he come yesterday?

becausehe was ill. 副词

he did not come yesterdaybecausehe was ill. 原因状语从句连词

因为他们挣的钱比我多，所以他们认为自己高人一等。

because they make more money than i do,sothey think they are so superior. 本句中so是不应该出现的

正确的是

because they make more money than i do, they think they are so superior.

因为：在英文中，because 和so不出现在同一句子中。

because it was raining, we stayed at home

= it was raining, so we stayed at home.

because it was raining, so we stayed at home. 这句话是错误的

since 语气比because弱一些，引导的原因状语从句通常表示已知的、显然的理由;通常在句首。

since/now that you dont love him, you should not marry him.

since / now that you are grown, you should make decisions on your own instead of relying on your parents.

显然已知的理由，但是没有because的语气那么强。

as 附带说明双方已知的原因，只是对主句的附加说明，重点在于主句。

as he is young, he is not qualified to the task.

i shall not be able to begin the work before i return as i am about to start a journey.

for 并列连词，引导的从句并不说明主句发生行为的直接原因，只提供补充说明，或表示推断式解释，一般不位于主句前，主从句间通常加逗号。

the day breaks, for the birds are singing.

he went to bed early, because he was tired. 直接的理由

he must be fired, for he went to bed early. 简介性的推断
