答案

"__Work hard ___ and then you can pass the exam"
这是一个 “祈使句+and+陈述句” 句式= If you work hard , you can pass the exam
又如 Do it this way and you will get a better result= If you do it this way, you'll get a better result
还有“祈使句+or +陈述句” 句式.例如 Hurry up, or you'll be late=If you don't hurry up, you'll be late.
还有“名词短语+and +陈述句”句式 例如 One more minute and I'll finish it=If I am given one more minute, i'll finish it.
