The debates about ICT and English teaching are centered on the way of using ICT in English classroom and the extent to which ICT can assist English teaching. In addition, more and more attention is drawn to how ICT shapes new language and literature experience within the English classroom. Many books are published to contribute to this field. Among them, the book 'Teaching Secondary English with ICT' edited by Anthony Adams and Sue Brindley places its focus on using ICT in secondary English classroom.展开更多
