Re: A grammatical error or not?

Yeah, I can see clearer now. I'm a Chinese. These years in China
American English has become increasingly popular. But in formal
instructional settings, grammars are taught strictly in traditional way
most of time, especially to teenagers or the younger. In this case, we
are not so familiar with some expressions which are so-called "not
grammatical correct" but commonly acceptable in real life. Thanks to
all of you!
