Present tenses - Examples and exercises

Ejemplo resuelto
Complete with present simple or present continuous:
"She ___ (read) a book right now." -> "She is reading a book right now."

Explanation: We use present continuous (am/is/are + -ing) for actions happening NOW. The clue is "right now". Present simple would be "She reads books every day" (habit/routine).
