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 when something happened more than once 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 来了 ！Here comes it again!
- 你 又 迟到 了。You came late again.
- 你 又 写 错 了。You wrote it wrong again.
- 你们 又 忘 了 我 的 生日。You all forgot my birthday 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 when something is about to occur
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), 应该 (yīnggāi), 能 (néng), and you'll notice that there's often a 了, indicating that something is about to happen.
