Welcome to this tutorial.
Today we're going to talk about the helping verb to be.
Let's get started.
Now we use auxiliary verbs which are also known as helping verbs to form questions negative sentences
compound sentences the perfect tense or the continuous tense and the passive voice.
Note that the basic auxiliary verbs are to be to do and to have
note that the helping verb to be can't be used as an auxiliary and a main verb.
Have a look at the following examples.
My sister is kind now in this sentence.
The verb is is the main verb and in this sentence My sister is cooking dinner.
The verb is is an auxiliary verb that helps to build the present continuous tense.
Cooking dinner
remember that the verb to be is irregular.
Have a look at the table below.
Now the base form of the verb to be is be present for M is or are past for was or were present participle
or gerund being past participle.
Been
now you can use the auxiliary verb to be a when you don't want to repeat something for example every
one was working that day but I wasn't meaning I wasn't working
B to deny something or see that it's not true.
For example you're being unreasonable No I'm not meaning I'm not being unreasonable
C to show interest in what somebody has said or to show surprise for example Kelly and Peter are dating
are they really showing surprise deals with.
So when you agree and neither or nor when you disagree.
For example I'm sleepy so am I.
I agree.
I'm sleepy too.
My parents are never late.
Neither are mine.
Meaning that my parents are never late either.
