Have to / has to

HAVE TO / HAS TO

Remember

·         “Have to” is used to express obligation (when something is necessary).   

 

           Ex. I have to make my bed everyday 

 

·         Has to is used with he, she, it (in affirmative sentences)

·         Don’t have to is used with I, you, we, they (in negative sentences)

·         Doesn’t have to is used with he, she, it (in negative sentences)

·         For questions we use “do / does + subject + have to"

·         We use “had to” to express obligation in the past

Fill in the gaps using “have to”, “has to”, “don’t have to”, “doesn’t have to”
