Santhoshkumarm, here´s a list of uses of WILL and WOULD. Hope they're useful! Please let me know if you have any doubt.
A key factor to remember about 'will' is that when we talk about the future we cannot always use 'will' and that when we use 'will' we are not always talking
about the future. In these examples
'will' is clearly referring to the future.
I'll probably visit Sue Kay when I go to Oxford.
If I see her, I'll tell her about it.
Next year she'll be 42. Or so she says.
However, in these examples 'will' is referring to events happening at the present.
My car won't start.
I'll answer that.
Will you have another cup of tea?
When we use 'will' referring to the present, the idea being expressed is usually one of 'showing willingness' or 'will power'. ?
My baby won't stop crying. I've tried everything and I'm really exhausted.
I am the boss. You will do as I say.
I need quiet to write this but he will keep on talking to me.
I wish he would leave me alone. Use 'will' for requests, orders, invitations and offers.
Will you help me?
Will you please sit down?
Will you have some cake?
I'll help you. Use 'will' for promises and threats.
I'll do it at once. I'll phone him immediately. ? I'll remember this.
I'll get my own back some day.
Use 'will' for insistence.
He will insist on smoking cigars during the meeting and it makes me ill.
He won't listen to reason.
Use 'will' for habit.
A cat will always find a warm place to sleep.
My car won't go any faster than this. Use 'will' for deduction.
The phone's ringing. That will be Mark.
I expect he'll want us to start without him.
Look again at all of these examples of 'will'. They are all to do with the present or are 'timeless'. Would (or the contracted form 'd) is sometimes used as
an alternative to 'used to' when discussing past habits:
'When we were young, we would spend (we'd spend) every summer holiday at the sea-side.'
'You would find him (you'd find him) sitting at the bar every lunchtime, drinking that strong black beer and chatting to the bartender until one day he was
there no longer.'
Would is also used to make polite requests:
'Would you be prepared to do all this work by yourself without any assistance?'
'Would you (be so kind as to) pick Jennifer up from school on Monday?'
Would (or its contracted form 'd in conversational English) is also associated with the conditional in its simple, progressive, perfect and passive aspects:
'There's no doubt about it. I would definitely (I'd definitely) travel to Mexico with you, if I could afford it.'
'You would still be (you'd still be) working for the World Bank, if you hadn't kicked up such a fuss.'
'I would have told you (I'd have told you) all about it, if you had phoned me.'
'If you wore smarter clothes, you would be invited (you'd be invited) to all the press conferences.'
