How to use "WILL" and "WOULD"?

Question

Please teach me the usage of Will and Would please.

Answer 1

"I will walk to the park." means You are walking to the park in the future. (You are definitely walking to the park in the future.)
"I would do it." Can mean 'I may do it.' or 'Maybe I will do it.'
"I would have done that." Means you had the capacity to do the action but did not. "I would have taken to dog to the vet."
"I would tell you to shut up, but then you would punch me." This time both 'woulds' mean one has the ability to do the action but does not perform it, or they may perform it.

Hope this helps.

Answer 2

"I will" refers to something you will do in the future.

I will eat my cereal. I will take the bus.

"I would" refers to something you might like to do, especially in certain circumstances. I would like to go with you. I would go there if you go with me. I would like to attend. I would like to go outside if its not too cold.

"I would have" refers to something you might have done in the past had the circumstances had been right: I would have gone if you had given me a ride. I would have cheered if they had made a touch down. I would have been happy if you had cleaned the house for me.

Answer 3

Will is used strictly to talk about the future.
Ex: I will go. <--Meaning you in the future you are going to go voluntarily.
Would is conditional.
Ex: I would go, if I could. <--Meaning you will go if a certain conditon is met, does not have to be voluntary.
