There are English English,American English,Scotch English,Irish English,and other kinds of English.Examples: "half past three" is English English,"half after three" is American English,"bairn"[1] is Scotch English,"I am after having my dinner"[2] is Irish English,"nor gold nor silver"[3] is archaic English,"Thank you for same"[4] is business English,[5] and "I don't know nobody here"[6] is vulgar English.
Advanced learners of English ought to pay attention to such details,and I think they will find it very interesting to go into the subject[7].But every learner of English is not an advanced one[8].I call it foolish of one to[9] attempt the subject before one has acquired the ability to speak,read,and write English as it is used by the average educated Englishman or American of today.One has yet much to learn before one can be properly called an advanced learner of English so long as one cannot read the news[10] or cannot express oneself[11] intelligibly to Englishmen or Americans in speaking and writing.
By "English as it is used by the average educated Englishman or American" I mean[12] everyday idiomatic English.It is practical,if that means actually used,but not if that means specially adapted to Chinese psychology[13].I have to mention this because it seems that many Chinese students have the mistaken idea[14] that while what is written about things Chinese[15] is practical.What is written about things foreign[16] is not practical.The fact is,however,that one cannot master English-that is,what I call practical English-by reading about things Chinese only.I would advise those who are in the habit of[17] confining themselves to[18] Chinese news when reading newspapers in English,to give up[19] the habit.
