当home单独使用即前后不加修饰词或短语时，不用定冠词：

当home单独使用时，可以直接跟在具有运动意义的动词之后，或紧随在具有运动意义的动词+宾语之后。换句话说，home可以当副词使用：

May I have permission to go home early? 能允许我早回家吗?

Not knowing what to do, I went home. 我不知道怎么办好，就回家了。

We arrived home towards evening. 快天黑时我们到家了。

当home之前或之后带有修饰词或修饰短语时，其用法和其他名词相同：

They went to their new home. 他们到自已的新家去了。

We arrived at the bride’s home. 我们到了新娘的家。

For some years this was the home of your queen. 曾有些年头这里是你们王后的家。

A mud hut was the only home he had ever known. 一间小土屋就是他所知道的唯一的家。
