探究reason在定语从句中的作用与用法

在定语从句中，reason作为连词，引导从句解释前面的名词或代词，表示原因或理由。

1. The reason why he was late is that his car broke down.（他迟到的原因是他的车坏了。）

2. The reason (that) I didn't go to the party was that I was feeling sick.（我没去参加聚会的原因是我感觉不舒服。）

3. The reason (why) she didn't come to work today is that she has a family emergency.（她今天没来上班的原因是她有家庭紧急情况。）

：reason后面的从句中，可以使用that或者why，why更为常用。另一方面，reason也可以作为名词，表示原因或理由。
