   Grammar
   Modal verbs in first conditional sentences

   💡 Remember!
     In the standard form of first conditional sentences, we use the present simple tense in the if-clause and will + bare infinitive in the main clause. Instead of will, we can use model verbs, such as can, must, may, might, should, etc. in the main clause to express ability, permission, necessity, possibility, advice, etc.

     If she trains harder, she can run faster than you. (ability)
     If you finish your paper, you can hand it in and leasve for home. (permission)
     If you want to have good mental health, you should balance your study and life. (advice)
     He may / might get a good job if he is good at IT. (possibility)
     You must get rid of all the distractions if you want to manage your time effectively. (necessity)
