New Century English 6BUnit Two Traffic and Traffic RulesLesson 2 Means of TransportMeans of Transport【教材分析】本课写作主题是交通工具。
要求学生写6-7句话介绍日常生活中使用的交通工具，并对不同交通方式进行比较。
【学情分析】学生非常熟悉交通工具这一话题。
在对不同交通方式进行比较时会涉及到形容词比较级的用法，预备班学生对此不是很熟练，因此是本写作任务中的难点。

Which is more expensive, traveling by light rail or by taxi?5. Which do you like better, traveling by air or by train? Why?设计说明：通过问答，使学生能初步谈论日常生活中使用的交通工具，并初步能使用形容词的比较级形式对交通工具作比较和评论。

可先进行小组讨论，然后汇总并口头朗读操练。
人称改变和动词形式的变化是难点。
