Answer 1

I must help the man who is badly hurt.
If you study hard, you will pass the exam.
What will it be if you become a proffesional athlete?

Answer 2

第一句话由祈使句+and+主句（常用一般将来时态）构成，转换成条件状从也就是变成由if引导的从句 (从句常用一般现在时，还需要补充出从句的主语，和主句的主语是同一个)，即 If you study hard, you'll。。。
第二句也就是提问条件状语从句的结果，这个就比较灵活，只要表达出将会发生什么就可以
What will happen if you become a professional athlete?
