Would be-- This is just one example verb with 'would': I would be happy if she danced with me.
First of all thanks for your co-operation but I am really sorry because I couldn't understand the difference between "Would" and "Would be" that you wrote in your reply. Explain me briefly why we need "be" with "Would"? Give me more examples please.
There is nothing special about 'would be', Quasim. 'Be' is just a verb, and all verbs can be used with 'would': would come, would go, would think, would seem, would be, etc. .
