人教版高中英語選修八選修8 Unit 2 Cloning Reading –Where is it leading us安徽省 - 亳州
Education background：
With the deepening of new curriculum reform, teacher's teaching way and students’ learning style must be changed. With the reform of English college entrance examination, how to build an efficient class and how to conduct English teaching are the questions we English teachers must think about.
I think English will certainly return to be instrumental and human. By learning English as a tool, we can develop the ability of listening, speaking, reading and writing, thus being able to communicate with others in English. In terms of humanity, learning English can broaden our horizons, enrich life experiences, raise cross-culture awareness, form good characters and correct life values.

The center topic of this unit is “cloning". Language skills and language knowledge mainly focus on "cloning”, the central topic.
