bentuk lamapu dari (+)They must go now (-)They must not go now (?)Must they go now jawab: (+)... (-)... (?)...

they had to go now
they didn't have to go now
did they have to go now?

kalo memang harus bikin bentuk lampau ya kayak gitu, tp sebenarnya must tidak ada bentuk lampaunya

semoga membantu :)

must = have to.

jadi sama aja cari bentuk past dari have to.

They must go now = they have to go now
past : They had to go now.

They must not go now = They don't have to go now.
past : They didn't have to go now.

Must they go now ? = Do they have to go now?
past : Did they have to go now?
