Penjelasan:

Dalam bentuk present tense maka to be yang dipergunakan adalah: is, am atau are, sesuai dengan subjek kalimatnya.

to be IS dipakai jika subjek kalimatnya adalah:

He, She, It,  singular noun (katabenda tunggal misalnya: My book, your father, The teacher, The cat, The government, Mr. President dst), atau uncountable noun (kat abenda tak bisa dihitung, misalnya water, milk, sand dst)

to be am dipakai hanya untuk subjek kalimat I

to be are dipakai jika subjek kalimat adalah: you, we, they. dan plural noun (kata benda jamak) misalnya My parents, two students, my cats, the people, his children, Rudi and Rita, My mother and my father dst.
