After the verbs can, must, may, shall, and will, use the infinitive without to , and not the third person of the present.
Don't use the past perfect unless there is another verb in the past tense in the same sentence.
Can changes to could in subordinate clauses, when the verb in the main clause is in the past simple tense.
Use the present tense in a future conditional in the if clause and the future tense in the main clause
But the future tense may be used in an if clause expressing a request: If you will/'ll give me some money I will/'ll buy you a drink.
Use the simple present (and not the present continuous) to express a present habitual action.
Use the present continuous to express a habitual action with the word always or with a verb denoting a continuous state: He is always talking in class; He is living in London.
