simple present

present simple. -form To conjugate the present simple we use the infinitive for the subjects "I", "you", "we" and "they" and for the third persons "he", "she" and "it", we add a "-s" to the end of the verb.   Note: There are spelling exceptions in the third person, according to the letter in which the verb ends. The rules are the same as those used to form the plural of nouns. Structure . 1. Affirmative Sentences Subject + verb. Examples:  I talk.   He eats.  They learn. 2. Negative Sentences Subject + auxiliary verb (to do) + negative auxiliary ("not") + verb. Examples:   I do not [do not] talk.  He does not [does not] eat.   They do not [do not] learn. Note: In negative phrases, the auxiliary verb ("to do") changes and the main verb goes in the infinitive. 3. Interrogative Sentences Auxiliary verb (to do) + subject + main verb? Examples:  Do you talk?   Does he eat?  Do they learn?  Note: As in negative sentences, in interrogative phrases the auxiliary verb ("to do") changes and the main verb goes in the infinitive. Uses 1. The present simple is used to talk about things that happen habitually. Unlike with Spanish, the simple present is not used to talk about something that is happening at the moment we speak. We usually use the present simple with adverbs of time:  always, every day, usually, often, sometimes, rarely, hardly ever, never ... Examples:   I always talk to my mother on Sunday.  I have never eats vegetables.   They usually learn something new in class. Exception: The adverbs of time go before the verb, except the verb "to be". When using "to be" the verb goes before the adverb. Examples:  I am always happy.   He is often sick.   They are rarely late. 2. It is used to talk about generalities or scientific facts. Examples:  He does not [does not] eat vegetables.  She works in a hospital.  Elephants live in Africa.   Bogota is in Colombia.  Do children like animals?  Adults do not [do not] know everything. 3. It is used for scheduled events in the near future. Examples:  The train leaves at 10:00.   The party is tonight.  Does the festival start tomorrow?  The plane does not [does not] arrive today. 4. It is used for instructions (the imperative). Examples:   Open the window.   Eat the vegetables  Do not cry   Do your homework  Call your mother.
