Present simple (настоящее простое время)
Это время выражает то, что мы делаем всегда, обычно, каждый день, иногда, часто.
В утверждениях и вопроспх используем вс глагол Do; со всеми местоимениями, кроме: (he, she, it)
Например:
Я улыбаюсь каждый день
+ I smile every day
- I don't smile every day
? Do I smile every day?

Когда задаем вопрос вс глагол выносим вперед.

! Но, когда мы видим местоимения:
She
He
It

В утвердительном предложении к глаголу добавляем букву "s". ! В вопросах и отрицаниях мы не приписываем к глаголу "s".
В отрицаниях с этими местоимениями используем doesn't
Например:
+ He smiles every day
- He doesn't smile every day
? Does he smile every day?
