I couldn't get a grant unless I had five years' teaching experience. (=if I did not have ...)
Unless you had done it earlier, you would have failed. (=If you had not done ...)
I shouldn't have gone to the door unless I had heard the bell. 要不是我听见门铃响,我是不会到门口去的。

Draw not your bow till/before your arrow is fixed. 箭搭好了才拉弓。
You can never gain your aim,unless you work hard. 你只有努力工作才能达到目的。
