Question

Conjuga sing=a canta ,write=a scrie
in Present Simple /A/N/I

Answer 1

I, You, We, You, They sing. (la 3sg adaugi un s la finalul verbului: He sings. )
Sing I, You, We, You, They? (la fel şi aici)
I, you, we, you, they don't sing. (la a 3-a singular e cu doesn't în loc de don't) .
Şi la "to write" e la fel.
