English plays a very important role in our daily life and has been a world language for decades, as the global economy is developing so fast nowadays, the learners of English have already realized that the main purpose to learn English is to communicate properly in their real life with the people from other culture, but not to memorize those boring grammar rules and terrible vocabularies which will appear in their English examinations. Consequently, it has become an important task for English teachers to think about how to develop students’ language abilities for real communication. Nowadays, Communicative Language Teaching(CLT) has become a very popular teaching approach in China. CLT pays a lot attention to the social and functional elements in language daily use.
