editor,

     You can find language pollution whenever you open a newspaper or turn on your TV set, listen to a

popular song at various advertisements. Language pollution exists almost everywhere and can be seen in

the following places:

     1. Chinese characters are written in the complex (复杂的 ) form. Although simplified Chinese

characters were accepted for use many years ago, it seems that more and more people like Chinese

characters written in the complex form.

     2. Many goods are produced in China but carry foreign names, which sound strange and have no

meaning at all.

     3. Words and expressions being used have a bad meaning. "Ba"(霸), which means bully in Chinese,

is one example. Now there are a lot of goods, restaurants, even factories or firms, with "Ba" in their names.

     4. There are too many incorrect grammatical expressions. Some films have strange names and

incorrect grammatical structures. "Ai ni mei shang liang', which means "I love you without consulting", is

grammatically incorrect and this kind of expression is now becoming popular.

     Some language experts point out that language pollution must be done away with, which is an idea

shared by myself and many others.
