Forming the Present Simple (affirmative)
The present simple tense is formed, in the affirmative, as follows
Subject + verb + object.
I + love + horseback riding.
I love horseback riding.
Conjugating the Present Simple (affirmative):
I love horseback riding
You love horseback riding
He/She loves horseback riding
We love horseback riding
They love horseback riding
Even though the differences between first-person (I) and third-person (he/she) in the present simple are not big, they are very important. The -s at the end of the third-person conjugation is extremely important. Similarly, it would be incorrect to say I plays football for a club.
Forming the Present Simple (negative)
The present simple tense is formed, in the negative, as follows
Subject + do + not + verb + object.
Amy + does + not + enjoy + musicals.
Amy does not enjoy musicals.
Conjugating the Present Simple (negative):
I do not enjoy musicals
You do not enjoy musicals
He/She does not enjoy musicals
We do not enjoy musicals
They do not enjoy musicals
The negative form of this tense is formed by pairing the main verb (enjoy in the case of the above example) with the auxiliary verb do in its negative form. As is made clear in the video, we can combine the two components of the negative form of this verb in a contraction, making the entire sentence flow more easily and allowing for more fluid conversation in spoken English (this way it will be easier for Amy to convey her disgust for musicals with greater facility of expression). The changes made in the contraction are as follows:
do not ⇒ don’t
does not ⇒ doesn’t
Therefore, our conjugation for the present simple (negative) should become
I don’t enjoy musicals
You don’t enjoy musicals
He/She doesn’t enjoy musicals
We don’t enjoy musicals
They don’t enjoy musicals
Forming the Present Simple (interrogative)
The present simple tense is formed, in the interrogative, as follows
Do + subject + verb + object
Do + you + play + the banjo
Do you play the banjo?
Conjugating the Present Simple (interrogative):
Do I play the banjo ?
Do you play the banjo ?
Does he/she play the banjo ?
Do we play the banjo ?
Do they play the banjo ?
It is important here to note the difference in punctuation. The question mark (?) is equally as important as the grammatical structure in marking the phrase as interrogative in written English.
