Since everyone is here, let’s start the meeting. 3. He knows a lot about medicine as he is a doctor. 4. They went to the park because the weather was nice. ③as, since, because 和because of用法辨析 用法 例句 since 意为“因为；既然”，侧重主句，从句表示显然的或已为人所知的理由，通常置于句首。 Since no one else saw these aliens, I refuse to believe you. as 意为“由于；因为”，从句表示双方已知的事实或显而易见的原因，用法与 since 差不多。 He knows a lot about medicine as he is a doctor. because 意为“因为”，更强调原因，经常用来引出听者或读者所不知道的新信息，如例句4；由why提出的问题必须用because来回答。 ※ because 不能与 so 连用。 1. They went to the park because the weather was nice. 2. — Why do you learn French? — Because I want to travel to France. because of 意为“因为；由于”，强调因果关系。because of 后跟名词、名词短语或人称代词宾格。而because后面跟一个完整的句子。 I like this book because of the interesting story. 学科网（北京）股份有限公司 $
