This note explains about the verbs expressing present .
Be is used in two ways. It is used as an ordinary verb. It is also used to form other tenses:
He is happy. ( Is is a form of be. In this sentence, be has been used as an ordinary verb. )
He is playing. ( In this sentence, the verb is playing. So be has been used to form another tense. )
When be is used to form other tense, it is called an auxiliary verb. It has the same form whether it is used as an ordinary verb or as an auxiliary verb.
|I am / I'm||I am not / I'm not||am I?|
|we are / we're||we are not / we're not||are we?|
|she is / she's||she is not / she's not||is she?|
Like be, have can also be used in two ways: (i) as an ordinary verb, and (ii) as an auxiliary verb to make other tenses. When it is used as an ordinary verb, it expresses possession.
|I have / I've||I have no / I've no||have I?|
|we have / we've||we have no / we've no||have we?|
