Verb "to be"

Verb "to be"

1.   It can be used to describe a noun in present, past and all other tenses the next way.

Pronoun	Verb “to be”	complement
I	am	tall
You	are	nice
He	is	short
She	is	happy
It	is	noisy
We	are	friends
They	are	cool

*always follow the same order, you can not say or write: he are, we is, or I are.

2.   Another use is to complement as a helping verb the progressive or continuous tenses:

Pronoun	Verb “to be” Helping verb	Verb + ing	complement
I	am	talking	to you
You	are	running	in the park
He	is	writing	on the notebook
She	is	dancing	in the concert
It	is	waving	its tail
We	are	traveling	to europe
They	are	drinking	coffe

*the same as in the other example, the pronoun and the helping verb to be never change to another combination like: we are.

*And when we use an action verb after the helping ver to be we must always use –ing to express in a correct way the verb in action in a continuous tense that can be present continuous, past continuous or future continuous, etc.
