...will take a second 只需要—会

take a second (minute)表示只需要一会的时间。在嘱咐对方“一会就好”时用成 This (it) will just take a minute 的形式。当然，如果主语是人的话，就会变成“腾出一点时间去做某事”。

例句：

It (This) will just take a second.

—会儿就行。

It really is only going to take a minute.

说真的，一会儿就行。

I have to take a minute to check it out.

我只好重新检查一遍。

You want to take a minute to think again?

你愿意再想想吗?

对话：

A: Aren't you finished in the bathroom yet?

还有人在洗手间吗?

B: Almost. It will take a second for me to get ready.

快完了，一会儿就好了。
