     Announcers on China Central Television (CCTV) will need to do some fast talking to replace the

popular English acronyms (首字母缩略词) they're now forbidden to use. Shanghai Daily reports that

"anchors at China Central Television [CCTV] have been banned from saying the English acronyms NBA,

CBA, GDP, and the like in their programs."

     The replacement for those handy acronyms? Chinese presenters must use the full Chinese name,

standardized by the State Administration of Radio, Film and Television.

     Although CCTV (oops, we mean China Central Television) presenters must already have a score of at

least 94 in their government-rated oral Mandarin proficiency exam (普通话等级考试), saying the full name

of organizations like the CBA or WTO-10 and 6 character's long separately-is sure to challenge even the

most skillful anchors. CCTV sports anchor Sun Zhengping tells Shanghai Daily, "A full Chinese explanation

of the English acronyms must be followed if my tongue slips. It is a little trouble but a necessary one because

not every audience member can understand the acronyms."

     Although the government isn't giving any official explanation for the shift, it is believed to have to do with

a proposal (提案) by Huang Youyi, director of the China International Publishing Group, at March's NPC

meeting. In his speech, Huang said, "With more and more publications mixing Chinese with English, measures

and regulations should be adopted to avoid English invading Chinese. If we don't pay attention and don't take

measures to stop the expansion of mixing Chinese with English, Chinese won't be a pure language in a couple

of years."

     Although China is far from the first country to take measures to protect local languages (the French and

Québécois beat them to it by a long way), acronyms are more about saving time than they are about corrupting

a language, we would think. Good luck to the CCTV anchors.
