Simple Present Tense
Grammatical Structures:
Subject+Auxiliary verb+main verb
(do) (base)
There are three important exceptions:
* For positive sentences, we do not normally use the auxiliary. * For the 3rd person singular (he, she, it), we add “s “to the main verb or “es” to the auxiliary. * For the verb to be, we do not use an auxiliary, even for questions and negatives. * Afirmative:

Subject + Verb(Present) + Complement.
Examples:
1. I play tennis.
2. He dances salsa music.
3. They eat breakfast.
4. The boy goes to school.
5. You need help.
* Negative:
Subject + Auxiliary (Do not/ does not) + Verb (Base form) + Complement. Examples:
1. I don’t play tennis.
2. He doesn’t dance salsa music.
3. They don’t eat breakfast.
4. The boy doesn’t go to school.
5. You don’t need help.
* Interrogative Questions (yes/no)
Auxiliary (Do/does)+ Subject + Verb (Base form) + Complement. Examples:
1. Do you play tennis?
2. Does he dance salsa music?
3. Do they eat breakfast?
4. Does the boy go to school?
5. Do you need help?
* Information Questions
WH Question Word + Auxiliary(Do/does) + Subject + Verb(Base form) + Complement. Examples:
1. When do you play tennis?
2. Why does he dance salsa music?
3. What do they eat for breakfast?
4. How does the boy go to school?
5. When do you need help?
Use:
We use the present simple tense when:
* the action is general.
* the action happens all the time, or habitually, in the past, present and future. * the action is not only happening now.
* the statement is always true.
Examples:
1. The train leaves every morning at 8 AM.
2. Cats like milk.
3. The party starts at 8 o'clock.
4. He has his passport in his hand.
Time Expressions
We often use some adverbs of frequency with the simple present tense to state how often somebody does something. Adverbs commonly used with the simple present tense are: always, usually, often, sometimes, occasionally, rarely and never. Note that the adverbs of frequency usually go before the verb. Structure: Subjetc + Adverb + verb (present) + complement.

Examples:
1. He often visits his grandparents.
2. I usually get up early.
3. She always carries an umbrella.
4. He never gets angry.
5. I sometimes read foreign periodicals.
6. They rarely watch TV.
7. She frequently buys detective stories.
Simple Past Tense
Grammatical Structures:
Subject+Auxiliary verb+main verb

Examples:
1. You swam in the pool.
2. She got up early.
3. They began to sing.
