Expressing "if… then…" with "yaoshi"
要是⋯⋯，就⋯⋯ (yàoshi..., jiù...) is one of several ways to convey "If... Then..." It is very similar to 如果..., 就... in usage and formality. However, it is important to note that 要是 is considered to be even more informal (and is usually left more to spoken Chinese) than the common 如果 and used more frequently in the northern areas of China.
要是 + Subj. ⋯⋯ ， 就 ⋯⋯
Note that the subject can also be placed before 要是. In this case, 要是 can be shortened as 要.
- 你 要是 真 想 我 ，就 给 我 打 电话 。If you do miss me, then give me a call.
- 要是 我妈 知道 这 件 事 ，我 就 死 定了 ! If my mother knew about this, I would be so dead!

- 你 要 再 说 ，我 真 生气 了 。If you keep talking this way, I'll get mad. Seriously.
- 他 要 不 听 ，我 也 没 办法 。If he doesn't listen, there's nothing I can do about it.
要不是 is pretty much the same as the English saying "if it weren't for."
