Simple Present Tense
The simple present tense in English is used to describe an action that is regular, true or normal.
We use the present tense:
1. For repeated or regular actions in the present time period.
2. For facts.
3. For habits.
4. For things that are always / generally true.
We form the present tense using the base form of the infinitive (without the TO).
In general, in the third person we add 'S' in the third person.
Subject | Verb | The Rest of the sentence |
I / you / we / they | speak / learn | English at home |
he / she / it | speaks / learns | English at home |
The spelling for the verb in the third person differs depending on the ending of that verb:
1. For verbs that end in -O, -CH, -SH, -SS, -X, or -Z we add -ES in the third person.
2. For verbs that end in a consonant + Y, we remove the Y and add -IES.
NOTE: For verbs that end in a vowel + Y, we just add -S.
To make a negative sentence in English we normally use Don't or Doesn't with all verbs EXCEPT To Be and Modal verbs (can, might, should etc.).
You will see that we add don't between the subject and the verb. We use Don't when the subject is I, you, we or they.
When the subject is he, she or it, we add doesn't between the subject and the verb to make a negative sentence. Notice that the letter S at the end of the verb in the affirmative sentence (because it is in third person) disappears in the negative sentence. We will see the reason why below.
Don't = Do not
Doesn't = Does not
I don't like meat = I do not like meat.
There is no difference in meaning though we normally use contractions in spoken English.
Word Order of Negative Sentences
The following is the word order to construct a basic negative sentence in English in the Present Tense using Don't or Doesn't.
Subject | don't/doesn't | Verb* | The Rest of the sentence |
I / you / we / they | don't | have / buy | cereal for breakfast |
he / she / it | doesn't |
* Verb: The verb that goes here is the base form of the infinitive = The infinitive without TO before the verb. Instead of the infinitive To have it is just the have part.
Remember that the infinitive is the verb before it is conjugated (changed) and it begins with TO. For example: to have, to eat, to go, to live, to speak etc.
