In urban China，where English is almost the official second language，many Chinese people have learned to speak as professionally as native speakers. However they may have an accent and make a few minor grammatical mistakes.Years ago many people used a certain Chinese-English dictionary or a series of textbooks and accepted their teachings. Consequently，language learners developed a peculiar vocabulary. Some people call these word choices “Chinglish”. The words are not incorrect—native speakers still understand them—but they stand in the way of using standard English. Here are some common examples, both from written and spoken English:
Clever (adj.): Native speakers usually say “smart” instead. “Smart” is a broader and more common word. “Clever” suggests an ability to think your way out of a specific problem or take advantage of a specific situation. Being smart serves you for life.
Examination(n.): Use “exam”, the short form of it, or the more common word, “test”. (The verb for all three words is “take”.) Another word you may hear is “quiz”. It means a short and relatively unimportant test that the teacher often gives as a surprise.
Film: This is largely a technical word. The common term is “movie”. (Native speakers often say “short film for the movie”.)
House (n.): a stand-alone building with its own street entrance that is home to one family. A home in a building full of families is an “apartment” or a “flat”. When in doubt, just say “home”.
Puzzled (adj.): We use this word to describe mild reactions to difficult math problems, and not even very often for this purpose (we say “I’m stumped” or “I have no idea” instead). But when we’re addressing a life issue such as whether to pursue (从事) a graduate education or go straight to work, we say “confused”. This is a stronger word as well as a more common one.
