Объяснение:
Глагол To Be- "IS" - пишется в единственном числе.
Например: SHE IS going to school.
HE IS going to school.
IT IS going to school.
Глагол To Be- "Am"- пишется когда говорим про себя.
Например: I AM going to school.
Глагол To Be- "Are"- пишется во множественном числе.
Например: WE ARE going to school
THEY ARE going to school
YOU ARE going to school.
Или же я учила когда их писать так =>
I AM
HE IS
SHE IS
IT IS
YOU ARE
THEY ARE
WE ARE
