I really want to shout out that I can't bare these dry chemical literatures!I have to select the useful documents of useful to me from so many foreign documents,download them and then read them time after time in case that I am not so familiar with those jerky professional vocabularies.It douts me that whether I am able to insist my major and seek for a professional work related.I am now fidgety,fidgety,fidgety,,,,,,,,
