中英合编的新教材对话内容丰富，适宜开展听、说、读、写各项活动。如何利用教材的对话课，培养学生的语言交际能力，是英语教学任务之一。怎样才能上好对话课呢？设计好对话课的教学是前提，落实对话课的教学步骤是关键。下面是本人在高二一学年的教学中的几点体会。

一、利用课本中的彩图进行词汇语境教学：

新编高中英语教材图文并茂，对话课的右上角几乎都有一幅与本单元对话教学内容相关的彩图。于是我就抓住学生对彩图较感兴趣的特点，进行词汇语境教学，让学生在师生问答的过程中熟悉本单元的对话内容并学习掌握单词，激起学生内在的学习动力，活跃课堂气氛。在第 61课，我以层层递进的设问引出新单词。

T：Look at the picture，please，What can you see in the picture？

S：Some boys.

T：What are they doing？

S：They are playing in the river. Some are playing with balls. Some are swimming.

T：Good. Some are swimming. We can also say they are bathing.

T：What are the two boys doing？

S：One is looking at his watch. One is putting his head under the water.

T：When he is putting his head under the water，can he breathe？

S：No，he can't.

T：Right，he can't. He has to hold his breath under water.

T：Why is one boy looking at his watch？

S：Because he wants to see how long the other boy can hold his breath under water.

T：Right. He is timing the other boy.

T：If the boy puts his head under water for too long，what will happen？

S：He will die by being under water for too long.

T：Good. We can also say he will drown.

T：Where do you live？

S：I live by the sea.

T：You live by the seaside，Can you tell us something about these aside？

S：There are a lot of stones or sand by the sea.
