The Present Indefinite Tense in the narration of past events gives the sentence some extra expression. It is usually used informally.

• Two days ago I go through the forest and see those dark figures hidden behind jasmine bush.

• A week ago he watches a concert of Michael Jackson and what does he realize!

Present Simple is used in stage directions to show actions taking place in a relative moment of speech.

• The reporter stands gazing fervently at Perkin for a second, then grasps his hand and shakes it vigorously.

Present Simple is used in complex sentences in subordinate clause after WHILE, BEFORE, AFTER, AS SOON AS, TILL, UNTIL.

• He’ll have a party after he passes all his exams.
• Millie will definitely read all those books while she is on holiday.
• Before I leave you we’ll drink one for the road.

In a complex sentence we use the Present Simple Tense in the if- and when-clause if the Future Tense was used in the main clause.

• If she comes it will be a big scandal.
• When I go shopping I shall buy some food.

Present Simple is used with vocal action verbs, such as acknowledge, advise, deny etc.

Those questions, which begin with “who” and ask for a subject of action, have the right word order and don’t need any auxiliary. The verb in such questions stands in the 3^rd person singular.

• Who stands under that huge tree?

• Who wants to live forever?
• Who dares to love forever?

Adverbs, such as often, always, seldom, usually, sometimes, never and etc., stand in sentences to indicate the Present Simple Tense.

• He hardly knows what happens next.

In the colloquial speech “not” is usually added to the auxiliary, so the word combination “do + not” is transformed into “don’t”.

• Don’t forget to water flowers!
• He doesn’t play football at all.
• I don’t need you anymore.
