1-When do we use it?
-When we are talking about a habit;
-When we are talking about a schedule;
-When we are stating a fact;
-When we say something that is generally true;
-When we give instructions or directions.
2-TIME EXPRESSIONS for things that happen regularly are: -Every.... -Once a.... -Twice a.... -On Tuesdays..... -In winters.... OR -Always, Frequently, Often, Usually, Regularly, Generally, Sometimes, Seldom, Rarely, Never. * Time Expressions that are one word, we put before the main verb. e.g. I always do my homework. e.g. We don't usually spend so much money.
* If the main verb is BE (am, is, are), we put the Time Expression after it. e.g. I am never late.
* When we have a sentence that is a general fact, we don't use any time expression and we have to know that it refers to PRESENT SIMPLE. e.g. The sun shines in the east. My father works in a factory. We live in Boston.
How To Use The Present Simple?
i) Affirmative form:
-Subject + Verb + Object e.g: I play football every day. ***3rd person of singular: -Most of the verbs take the letter “s” to from 3rd person of singular, e.g.: Live-lives Work-works
but …the verbs ending in “sh, ch, o, x, ss”, we ad “es”
e.g.: wash-washed, teach-teaches, go-goes fix-fixes kiss-kisses
and…the verbs ending in consonant + letter “Y”, we cut “y” and add “ies”.
e.g.:
fly-flies cry-cries study-studies
but…the verbs ending in vowel + letter “Y”, we add “s”.
e.g.:
play-plays say-says Stay-stays
ii) Negative form:
-To do the negative form in present simple tense, we must use the auxiliary “to do”.
-Subject + verb to do (conjugated) + not + main verb (infinitive) + the object. e.g.: I do not play tennis every day. She does not work in my company.
