If you have things to do or a brilliant idea on your mind to tackle later, make a note.

如果你有事情要做，或者脑子里有一个绝妙的主意要处理，做个笔记。

I'll make a note of our next meeting in my diary.

我将把下次会议的事记在我的记事簿上。

Make a note of the questions you want to ask; you will invariably forget some of them otherwise.

把你想问的问题记下来；否则你准会忘记其中几个。

I knew that if I didn't make a note I would lose the thought so I asked to borrow a pen or pencil.

我知道如果我不做一个记录我就会忘记这个想法，于是我要求借支钢笔或铅笔。

B: Yes, Sir. I'll make a note of it.

好的，先生，我会记下。
