because原因状语从句用法 "because"引导的原因状语从句用来说明造成主句情况的原因。它可以放在句首或句中,并且主句和从句之间需要用逗号隔开。 例如: - I didn't go to the party because I wasn't feeling well.(我因为身体不舒服没有参加派对。) - He failed the exam because he didn't study hard.(他因为没有努力学习而考试失败。) - She left early because she had an appointment.(她因为有个约会所以提前离开。) 需要注意的是,原因状语从句通常引导一个句子,而不能单独存在。如果原因状语从句位于句首,则主句后需要有逗号分隔。如果原因状语从句位于句中,则从句前后不需要逗号分隔。 例如: - Because it was raining, she decided to stay at home.(因为下雨,她决定呆在家里。) - She decided to stay at home because it was raining.(因为下雨,她决定呆在家里。 本文来源:https://www.wddqw.com/doc/13da3f12bb4ae45c3b3567ec102de2bd9705de1a.html
