Explanation / Penjelasan:

Untuk setiap bentuk tense, itu ada rumus-nya masing-masing:

1. Present Continous
   Subject + to be (present) + Verb-ing
   
   Dasarnya Present Continous ini menjelaskan kejadian yang sekarang sedang terjadi/dilakukan.
   Contoh:
   "Now... Tevin is Tutoring English", yang artinya...
   "Sekarang... Tevin Sedang Mengajar Bahasa Inggris"
   
   
2. Past Continous
   Subject + to be (simple past) + Verb-ing
   
   Sama seperti Present Continous, tapi ini menjelaskan kejadian yang sedang berlansung di masa lalu.
   Contoh:
   "Yesterday Tevin was Tutoring English", yang artinya...
   "KemarinTevinSedang Mengajar Bahasa Inggris"
   
   
3. Future Continous
   Subject + Will be + Verb-ing
   
   Future Continous adalah bentuk kalimat yang menjelaskan kejadian yang akan berlansung di masa depan.
   Contoh:
   "Tomorrow Tevin will be Tutoring English", yang artinya...
   "BesokTevinAkan Mengajar Bahasa Inggris"
