Choose the correct helping verb

1. Use the subject to decide am / is / are:

• I → am
• He / She / It and one person / one thing (cat, dog, student)
  → is
• You / We / They / Plural nouns (cats, dogs, students ) → are
  

2. Use the -ing form of the main verb

After am / is / are, always use verb + ing.

Example: They are playing.

 Verb Spelling Rules When Adding -ing

 Rule 1: Most verbs → add -ing

• play → playing
• read → reading

 Rule 2: Verb ends in -e → remove -e, add -ing

• write → writing 
• make → making
• take → taking

Rule 3: Double the final consonant only when the verb ends with one vowel + one consonant AND the vowel sound is short.

Examples

•sit → sitting (short vowel)

•run → running (short vowel)

•stop → stopping (short vowel)

NOTE: No doubling the final consonant:

•eat → eating (long vowel sound)

•read → reading (long vowel sound)

Rule 4: Verb ends in -ie → change -ie to -y

• lie → lying
• die → dying

Rule 5: Verb ends in -y → just add -ing

• carry → carrying
• play → playing
• obey → obeying
