Unfortunately, Chinese language education is based on written exams. Language majors in
Western universities write papers and have oral exams. Chinese teachers of English are
loathe to grade papers. Grammar rules make wonderful multiple choice exam questions for
lazy teachers.

Sad, but true. Chinese English textbooks are riddled with grammatical errors too. The other day, I picked up an IELTS textbook and began flicking through the pages. On one of the first pages I read the following -

'I used to enjoy going to the movies, but now I watch movies at home because it's much comfortable.'
'People in Northern China will often chose rice as part of their main meals.'

Whose name is printed all over such rubbish as this? None other than 'Global IELTS'.
