　　1. Background
　　With the development of world economy， English as a tool for global communication is becoming gradually important and popular. Although the number of native speakers of English （335 million） is not very large compared with that of Mandarin （1197 million） and Spanish （406 million）， most people use ESL or learn English as a foreign language （EFL） （ESL 2013）. According to Crystal （2012）， the international status of English greatly enhanced to improve than other languages in society. English is the official language of many international organizations including the European Union and the United Nations as well as British Commonwealth countries. Hence， English is becoming a useful and even necessary language to know， many people prefer to study it as a second language all over the world.
　　English as an international language and global language started to be widely learnt and taught from the 19th century. There has been consistent growth in the number of English language learners. As a result， more tutors will be needed to teach English. A report published by the British Council estimates that more than 100 million students in 100 different countries learn English since 20th century and around 2 billion people will be learning English during the next decade （British Council 2017）. For instance， international English language testing system （IELTS） has been recognized by 135 countries around the world by 2014. Every year more than 2 million students take the IELTS test （IELTS 2017）. Thus， many countries require to employ English teachers and there is an argument about the native English-speaking teachers （NESTs） or non-native English-speaking teachers （NNESTs） are better to teach English to foreign students.
