Яне могу понять как это делать​

Do Candice and Alfonso walk to school? - No, they don`t.

Does Mary watch TV in the afternoon? -Yes, she does.

Do they play basketball on Saturdays? - No, they don`t.

Does Chris eat meat every day? - No, he doesn`t.  

Does Mr Key swim in the sea? - Yes, he does.

Cмотри, если he/ she/ it - т.е. 3 лицо, то в вопросе does? а в глаголе буквы "s"  не будет

если 1 лицо или мн.ч - то в вопросе "do"?

don`t- это сокращение от do not

doesn`t - does not
