1............... you do that again, I will tell your mom.
Wrong!
Use "If" for a condition that may make the result happen.
2............... she started at 6, she should be here by noon.
Wrong!
Use "If" to introduce a possible situation: "If" she started at 6, she should be here by noon.
3............... you stop smoking, your health will not improve.
Wrong!
"Unless" means "if not" in this sentence.
4............... they offered me the job, I would take it.
Wrong!
Use "If" for an imaginary condition with "would" in the result clause.
5............... she arrived now, we would be in trouble.
Wrong!
Use "If" for an unreal present possibility followed by "would".
6I cannot continue ............... there is someone to help me.
Wrong!
"Unless" means "if not", so help is necessary for continuing.
7Children cannot go out at night ............... they are accompanied by an adult.
Wrong!
"Unless" shows that being accompanied by an adult is the required condition.
8You can't share my apartment ............... you pay the rent.
Wrong!
"Unless" means you can share the apartment only if you pay the rent.
9............... you find a job, your problems will only deepen.
Wrong!
"Unless" means "if not", so finding a job is needed to avoid deeper problems.
10............... it does not stop raining, we will have to cancel the trip.
Wrong!
Use "If" before "does not" to give the negative condition for canceling the trip.
11............... you do not meet the deadline, you will be sacked.
Wrong!
Use "If" before "do not" to give the negative condition for being sacked.
12............... you buy the tickets, I will bring the drinks.
Wrong!
Use "If" for a condition that will lead to the speaker bringing the drinks.
Done.
