教学建议
对话建议
方法一：
教师要充分利用教材上提供的用餐话语，食物名称对学生进行口语方面的训练, 把表达用餐的日常用语、词组编对话，编类似情景的对话并表演。
方法二：
教师组织学生分成几组，用竞赛形式把食物的名称用英文让学生写出来；看哪一组学生对食物名称的了解多，可写：蔬菜、肉类、水果、饮料及其他食物。
方法三：
教师准备好图片，让学生们说出自己喜欢的食物并且采取互问，比如：西红柿、豆腐、 咖啡等，增加对所学的单词的记忆。
课文建议
教师把这堂课的内容简述给学生：教师通过听磁带，阅读，问答，分组讨论，图片显示来完成本堂课的教学任务，教师在讲解此课时，特别是在谈论corn, 重点说明discovery, spreading, usage and the way of making food with it.
教材分析
本文的交际用语为用餐的表达法，如：Would you like…? How about…? Help yourself..这些词语较简单，学生能够容易运用，同时教材中列出不同的食物名称，短语，练习分别让学生们掌握和分组讨论。阅读课仅用一篇文章说明世界各地的日常食物的来源及产生的背景，如：玉米的发现，土豆、水果的种植。同时本单元是一个复习课，Lesson 31重点复习了定语从句中的先行词指人、物时，关系代词的使用。

T: There are some differences in table manners between the western countries and China. If an American or Englishman invites you to dinner, you’d better arrive on time. You can arrive a few minutes late but you can’t arrive early. While eating, you’ d better put your table napkin on your knees not around your neck if there is any. In China, we usually serve dishes first and then soup, while in the West, people prefer to serve soup before dishes. In China, hosts are always toasting wine and picking up food for their guests again and again but in the west especially in America, hosts only offer food once. If you want to have more, just help yourself to it. Don’t pretend to be refined. The host won’t offer a second time. Hosts like their guests to help themselves. If you don’t know the taste of a dish, you can taste a little. You mustn’t refuse what your host offers you. If you don’t like it indeed, you can honestly say; Sorry. I’m not used to that. Thank you. But you must eat up all the food put in your plate, finish all the wine put in your glass. Don’t make any noises while eating. Don’t put your plate close to your mouth or put you mouth into the plate. You should help your host/ hostess to set the table before the dinner. After the meal you ought to offer your host the help to clear the table.
