English Grammar: Present Continuous Tense

Study Notes

The present continuous tense is formed using the present tense of the verb "to be" (am, is, are) + the present participle of the main verb (-ing form)
The formula: Subject + am/is/are + verb-ing
Examples:
- I am studying English.
- She is writing a letter.
- They are playing tennis.

The present continuous uses the -ing form of the main verb
Spelling rules for -ing form:
- Most verbs: add -ing to the base form (e.g., walk -> walking)
- Verbs ending in -ie: change -ie to -y and add -ing (e.g., die -> dying)
- Verbs ending in a consonant + -y: change -y to -i and add -ing (e.g., hurry -> hurrying)

Mistakes with verb forms:
- Incorrect use of the base form instead of the -ing form (e.g., "I am go to the store" instead of "I am going to the store")
- Incorrect use of the past participle instead of the -ing form (e.g., "I am written a letter" instead of "I am writing a letter")
Mistakes with subject-verb agreement:
- Incorrect use of the singular or plural form of the verb "to be" (e.g., "I are studying" instead of "I am studying")
- Incorrect use of the verb form with collective nouns (e.g., "The family are going" instead of "The family is going")
Mistakes with sentence structure:
- Incorrect use of the present continuous with stative verbs (e.g., "I am knowing the answer" instead of "I know the answer")
- Incorrect use of the present continuous to describe a permanent or general truth (e.g., "The Earth is rotating around the Sun" instead of "The Earth rotates around the Sun")
