A: Hi, Mary. How've things been? I haven't heard anything about your
            English investigation for weeks. What're you studying now?
            B: Now it's negative-“no”and“not”, to be specific.
            A: There's nothing particularily unusual about “no”and“not”, is
            there?
            B: Not a lot, really. The main thing seems to be that “not”is used
            with verbs, and “no”everywhere else.

            A：你好，玛丽。你过得怎样？我有好几个星期没听到有关你研究英语的情况了。你正在学习什么？
            B：现在正在学否定词--“No”和“Not”。
            A：对于“No”和“Not”没有什么特别要注意的地方，是吗？
            B：的确没有什么，看来主要点在于“Not”和动词连用，而在其他地方用“No”。
