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要害。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爱好的特点，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把握单词，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.

T：Thank you. We can call the place by the river or sea “beach”.（画线部分为本课的新单词）

在边进行上面的教学活动时，我边在黑板上进行了以下的板书：

bathe：to go swimming

time（v）：to record the time taken by…

drown：die by being under water for too long

hold one's breath under water

seaside：the edge of the sea

beach：the place by the river/sea/ocean/lake covered by sand or smooth stones

二、听录音，了解对话内容，进行日常用语操练

对话课侧重于日常交际用语的学习。从知识操练到交际能力培养主要是利用听说活动来进行的。于是，我就以听说为对话课的主旋律，进行话题日常交际用语的操练。下面就以第 21单元对话课的设计来进一步地说明。

听对话录音前介绍与对话内容相关的背景知识，并设计如下的表格：

What kind of music does Mary want for the party？

Time Music At the beginning After dinner At the end

要求学生带着上面表格中的问题去听对话录音，并进行填空回答，为下一步所要进行的日常用语操练作好话题预备。

答案为：

Time Music At the beginning quiet and peaceful music After dinner jazz or pop songs At the end familiar songs
