Complete the following sentences using an appropriate conditional form.
In the first conditional, we use a simple present tense in the if-clause and will/can/may + infinitive in the result clause. First conditional sentences are used to talk about real and possible situations.
1If he doesn’t mend his ways, he ............... in serious trouble.
Wrong!
Use "will land" for the likely future result in a first conditional sentence.
2If you ............... hard, you will pass the test.
Wrong!
Use "work" because the if-clause of a first conditional sentence takes the present simple.
3If he ............... now, we can all have dinner together.
Wrong!
Use "arrives" because the third-person singular present simple needs -s.
4If you ............... her, she will not come.
Wrong!
Use "don't invite" because the if-clause refers to a real future possibility in the present simple.
5If I don’t meet him, I ............... to his mother.
Wrong!
Use "will talk" for the future result of a possible condition.
6If she ............... English, she will get a better job.
Wrong!

Wrong!
Use "will be" for the likely future result in the main clause.

Wrong!
Use "finds" because the third-person singular present simple needs -s.

Done.
