because of和because用法区别

Question

如题所述

Answer 1

because 和because of 都可以用来表原因（引出从句或者短语做原因状语）
但在用法上两者不一样：
A: because 是从属连词， 后接原因状语从句
如：
1. He didn't go to school yesterday because it was raining.
由于下雨，他昨天没上学。
2. John didn't attend the meeting because he was ill.
约翰没有出席会议, 因为他病了。

比较：
B：because of 是个短语介词，不可以引导原因状语从句，而应该接名词，代词等
如：
1. He didn't go to school yesterday because of the rain.
由于下雨，他昨天没上学。
2. John didn't attend the meeting because of his illness.
约翰没有出席会议, 因为他病了。

拓展：
1. because, as, since, now that 等引导原因从句
2. because of 等于owing to; thanks to; due to; on account of 后接名词或者代词。
