Note:
In writing conditional sentences,we may put the”IF clause”before the “RESULTS clause”and vice versa.However, we must put comma(,) at the end of the “RESULTS clause”.
Also the meaning of the FACT must be on the contrary with the conditional sentences.So if the conditional sentences is in positive form,the fact will be in negative one and vice versa.
Unless = if not
