Sam gets up early. Marisa doesn’t get up early. She stays in bed until 10 o'clock.
He drives a car. She doesn’t drive a car. She rides a bike.
He works in an office. She doesn’t work in an office. She stays at home.
He has lunch in a restaurant. She doesn’t have lunch in a restaurant. She makes lunch at home.
In these sentences, we're contrasting the daily routines of Sam and Marisa by using the present simple tense in both negative and positive forms. The present simple tense is commonly used to describe habitual actions or routines.
For the negative form, we use "doesn't" (the contraction of "does not") followed by the base form of the verb.
For the positive form, we simply use the third person singular form of the verb (in this case, adding 's' to the base verb for Sam, and using the base verb for Marisa, as we're filling in her routine).
This exercise helps illustrate not only the differences between Sam's and Marisa's routines but also provides a practical application of forming both negative and positive sentences in the present simple tense.
