Asking questions in the present simple tense: How and When to Use in English

-Does Timmy live in London? -No, he doesn't. To form questions in the present simple when the subject is Timmy (=he), follow the structure does + subject (in this case, Timmy) + verb without -s at the end (here, live) + any other elements (e.g., in London). Example: -Does he play guitar? -Yes, he does.

-Why do you swim? -To stay healthy. Here, the subject is you, so we follow this structure: question word (why) + do + subject (you) + verb (swim). We also use do with the subjects I/we/they. Example: -Why do they play tennis? -Because they enjoy it.

-When does he run? -He runs in the morning. Here, the subject is he, so we use does and follow this structure: question word (here, when) + does + subject (he) + verb without -s at the end (run). Remember that in questions with does, the main verb does not need an -s at the end. Example: -Where does she go? -She goes to school.

-Do they study English? -Yes, they do. To form questions in the present simple we generally use do and does. Here, the subject is they, so we follow the structure: do + subject (here, they) + verb (study). We also use do with the subjects I/you/we. Example: -Do you play the piano? -Yes, I do.

-What does she eat? -She eats pasta. Here, the subject is she, so we use does and we follow this structure: question word (what) + does + subject (she) + verb without -s at the end (eat). Example: -What does he read? -He reads novels.

-Where do you come from? -I come from India. Here, we follow the structure: question word (where) + do (because the subject is you) + subject (you) + verb (come) + the rest of the question (from). Remember that we use do with the subjects I/you/we/they. Example: -Where do they live? -They live in Canada.

-Does Roger go to his office? -No, he goes to the park. With a subject like Roger (=he), or with subjects like she or it, ask questions by following this structure: does + subject (here, Roger) + verb without -s at the end (here, go) + the rest of the question. Examples: -Does she enjoy swimming? -Yes, but she prefers running; -Does it help? -No, it doesn't.

-Do you like pizza? -Yes, I do. If the subject is you (singular or plural), form a question with do + subject (here, you) + verb (in this case, like). Example: -Do you miss home? -Yes, I do.

-Where do they live? -They live in New York. When your question includes a question word and the subject is I/you/we/they, follow the structure: question word (here, where) + do + subject (they) + verb (live). Example: -When do they leave? -They leave at 6 o'clock.
