There are two tenses in English: past and present.

The present tense is used to talk about the present and to talk about the future.

There are four present tense forms:

Present simple: I work

Present continuous: I am working

Present perfect: I have worked

Present perfect continuous: I have been working

We can use all these forms:

  • to talk about the present:                                           

London is the capital of Britain.

He works at McDonald’s.

He is working at McDonald’s.

He has worked there for three months now.

He has been working there for three months now.

  • to talk about the future:

The next train leaves at this evening at 1700 hours.

I’ll phone you when I get home.

He is meeting Peter in town this afternoon.

I’ll come home as soon as I have finished work.

You will be tired out after you have been working all night.

Hello lotusflower123,

Both forms are acceptable and have the same meaning. I would say that '...after working...' is more common but '...after you've been working...' would be a good way to emphasise the point. For example, you might imagine a context like this:

New worker:  This job is easy!

Experienced worker:  You think so? You wait until you have a night shift. You might think it's easy now but you will be tired out after you have been working all night, trust me.

 

Best wishes,

Be.
Don't be.

Above commands are correct
We can use DONT with the verb BE in command

We do not use do/does with am/is/are/was/were

Kirk sir I am not expert in grammar, but I have practical experience.

This is the question , I have not answered yet to my students,

Why do we not use do/does with the verb BE in simple present ?

Hello INS-PRAKASH,

It's great that you and your students have noticed this apparent contradiction to the rule about not using 'don't' with 'be'. The case here is different, as you've noticed, because it's an imperative and not, for example, a present simple form.

There are historical reasons for the auxiliary verb 'do' not being used with 'be', but I'm afraid this is not a subject we address here at LearnEnglish. Although there are logical structures in languages and we sometimes speak of reasons in explaining grammar, in the end, languages are created through the way people speak over millenia. We focus on helping people learn how to speak English as it is used nowadays and less on explaining why, which is more in the domain of historical linguistics.

By the way, as a teacher you might be interested in our sister site TeachingEnglish. If you haven't already checked it out, you might find some useful materials there.

All the best,

Kirk sir, thank you, you always help us and solve our doubts
(^_^)

so I say to him, 'What's your game, son?' past??
why it's not= so i said to him, 'What's your game, son?'

Hello Adham farea,

This use of present forms is described on the page:

 

to talk about the past when we are telling a story in spoken English or when we are summarising a book, film, play etc.

 

When we tell an informal story such as an anecdote or joke present forms are quite common. They make the story more immedaite and can bring it to life, making it more engaging for the listener.

Why 'is' and not 'has'?

'Most modern birds require parental care – the brush turkey of Australia (which is no relation to American turkeys) is one of the few exceptions.'

Thanks in advance.

Hello feli3105,

That sounds odd to me, too, so I'm afraid I can't explain that. 'have' or 'bear' are the verbs that are typically used in such a phrase.

Hi :) whats the different between

I’ll come home as soon as I have finished work. AND
You will be tired out after you have been working all night.

Hello Elsa99,

'I have finished work' is the present perfect simple and 'you have been working' is the present perfect continuous. The difference between these two forms is explained on our present perfect and present perfect simple and continuous pages.

If you have any other questions about these sentences, we're happy to help you, but please explain to us what you understand and don't understand so that we can help you better.

All the best,
