害

吸烟对身体只有害处，没有任何好处。

Smoking does nothing but harm to your health; it brings no benefits at all.

我们要分清楚什么是利，什么是害。

We need to distinguish clearly between benefit and harm.

你这样做不仅会害了你自己，也会害了别人。

What you are doing will harm not only yourself but others as well.

昨晚外面的声音害得我一整夜都没有睡好觉。

The noise outside last night kept me awake all night.
