Confuse in the -ould word

February 6, 2008

I am still do not know how to use the “can” and “could” or “will” and “could” correctly I think. According to my “teacher”, “can” or “will” is use when you are “for sure” type of sentences. And “could” or “would” is use when you just estimate something and just a “maybe” sentence. I wonder whether I should use the “-ould” for most of the sentences or not.

Why learning English could be so difficulty? I am very greedy not to study hard when I was little. Why my parent do not sent me to English school and why I am so stupid in learning language?
