Please help correct #1

Hi everyone, since everyday I have a lot of questions about English usage coming into my mind. They seem to be my common questions whenever I'm going to speak or write. Now I think that these doubts might considerably obstruct my English learning, so I came up with an idea that I should put all those questions on a blog and let everyone who are skillful at English to correct them. You know, even the introduction of this message I'm writing, I'm still not sure whether or not the grammar is correct.

As a consequence of this big problem, I would like to eliminate that obstacle and ask everyone to help me solve the problem by taking a look all of the following sentences and making a correction if they are wrong. (If the introduction is incorrect, please also do so) :)
