PENJELASAN :

Rumus Simple present tense

Verbal (dengan kata kerja) : S + V(s/es) +O

Nominal (tanpa kata kerja) : S + is/am/are + O

Simple present tense digunakan untuk menyatakan kebiasaan atau kejadian yang terjadi saat ini. Selain itu, simple present tense juga digunakan untuk menyatakan kebiasaan sehari-hari, rutinitas sehari-hari, dan kegiatan yang dilakukan secara berulang-ulang.

Do : I, you, we, they

Does : She, he, it

Pada kalimat negative dan interrogative Vs/es kembali ke V1 karena sudah ada "does"
