if you were born in united stated you would be able to comunicate english well. tolong di ubah ke conditional (fact)

Mungkin begini:
Conditional sentence:
If you were born in US, you would be able to communicate English well.

The fact:
You aren't born in US. You are born in Indonesia, so it is unlikely for you to speak English well. Except you study hard to learn English, then eventually you will be good at it.

Jadi maksudnya, kondisi awalnya aku bilang ke kamu kalo seandainya kamu lahir di Amerika, pasti kamu bakalan bisa ngomong dan komunikasi pake bahasa inggris dengan lancar.
Tapi faktanya, aku tau kamu cuman kelahiran Indonesia, jadi bahasa inggrismu pas2an. Kecuali kalo kamu belajar bahasa inggris dengan tekun, mungkin suatu saat kamu bakal bisa bahasa inggris dengan lacar kayak English native speaker.

Semoga membantu..
