Question

Kapan kita menggunakan "Present Progressive Tense sama Past progressive tense" ??

Answer 1

It's my opinion :)
Present progressive tense itu dipakai untuk aksi berkelanjutan yang lagi dilakuin saat itu. Mirip kayak present tense, tapi dia ada to be nyaa.. E.g : I am walking.
Past progressive tense itu sama aja kayak present progressive, cuma dia dilakuin di masa lalu. E.g : I was walking.
