tolong ubah ke simple past tense

2. (-) we won't eat meatball next time.
(?) will we eat meatball next time?

3. (-) you/I don't understand the material
(?) do you understand the material?

4. (-) she is not/ isn't watch TV at night.
(?) is she watch TV at night?

5. (-) we won't help you to finish your homework.

6. (-) you aren't / are not speaking with Mr. Smith.

PS : yg soal nomor 5 agak kurang nyambung kalimat, jadi kurang yakin jawabannya juga nomor 6 ga terlalu yakin.. mohon maaf bila salah

Semoga bermanfaat
Jawabannya bener kok Klo yg (+) pakai verb 2
