Expressing "again" in the past with "you"
Whenever you want to express something like "you did it again!" in Chinese, you generally want to use 又 (yòu).
又 Used in the Past
Normally, 又 is used to express an action that has already happened again for (at least) the second time. It doesn't have to be in quick succession; it happened before, and now it's happened again.
又 + Verb + 了
- 又 下雨 了 ！It rains again!
- 你 又 迟到 了。You came late again.
- 我 又 写 错 了。I wrote it wrong again.
- 宝宝 又 哭 了。The baby is crying again.
- 他 又 喝 醉 了？He got drunk again?
Colloquial usage 又来了
"又来了" fits the above pattern, but is also a little tricky because it expresses something that is still ongoing, and has already started as the speaker is speaking. Literally it's say, "here it comes again," but it's more accurate to translate it as "there it is again," or "there [he] goes again." It indicates that the speaker is a bit annoyed that it happened again.
又 Used in the Future
When it becomes clear that something is about to happen again, you can also use 又. It's almost as if it has already happened in your mind. In these cases, it's quite common for 又 to be immediately followed by 是 (shì), 要 (yào), 可以 (kěyǐ), 能 (néng), and you'll notice that there's often a 了, indicating that something is about to happen.
又 + 是 + Noun
又 + 要 / 可以 / 能 + Verb Phrase ( + 了)
- 明天 又 是 星期一！Tomorrow will be Monday AGAIN!
- 我 又 要 迟到 了。I'm going to be late again.
- 今晚 又 要 加班！Tonight we're going to work late again!
- 老板 请客，又 可以 吃 大餐 了！The boss is going to treat us. We can have a big meal again!
