Furthermore, newly learned words are seldom put into use. This arises because everyone in China communicates through Mandarin or a regional Chinese dialect, and English is perceived to be of little use in the country. This has been further reinforced through the national Band 4 examination where 80% of the test is the writing component, 20% is devoted to listening, and speaking is excluded entirely. According to a national survey, only half of the teachers consider that vocabulary should be learned through conversation or communication. A far smaller percentage support activities such as role-playing or vocabulary games.
