虽然 “beside” 和 “besides” 在拼写上只差一个字母 “s”，但它们的意思和用法却完全不同。它们的不同点具体是什么？

“Beside” 是介词，表物理方位 “在…旁边”，相当于更正式一点的 “next to”。

Put the chair beside the table.

Come and sit beside me.

The cinema is beside the park.

“Besides” 作介词用时，意思为 “除了…之外，还/且”，类似于 “as well as”。

Besides knowing grammar well, you need to have a good vocabulary.

You should do something else besides studying.

Besides enjoying reading, she loves playing football.

“Besides” 作副词用时，意思为 “此外，况且”，通常用来添加更重要或更强烈的观点，相当于不那么正式的 “moreover”。

I'm going to practise now because I've got time and besides, I need to!

I want to go and lie down. Besides, I have a headache.

I don't want to drive now. Besides, it's really dark.
