写作建议
本单元训练学生写中国和加拿大的区别，首次出现这样的练习，老师要给学生一些必要的提示。提醒学生都包括哪些方面，应先说什么，后说什么。先口头说出，再写下来。老师可先给学生一些问题，让学生回答，如学生回答对了，让学生把这些答语写出来，老师再指导学生将这些答语连成句子文章，比如：
Same as China
Different from China
Large land
Canada(第4页) has 2 official languages
Weather is different from area to area,
long and hard, winters in the north
Six time areas
Many lakes
Smaller population
Much coal, oil and gas
No places as hot as south China
More fresh water
A lot of forests
教材分析
本单元在对话课中主要介绍了美国英语和加拿大英语的不同点：如发音、用法和拼写等方面。课文用两篇文章让学生们简单了解加拿大国家的概况及文化背景知识，在27课中教材用一些练习帮助学生们了解和掌握主谓一致的用法和运用。
教学重点难点
1.be famous for的讲解
以……著名[其同义词组为be (well)known for
Hangzhou is famous for its beautiful scenery. 杭州以优美的风景而闻名。
be famous for 与be famous as的区别
1) 当主语是表示人的名词
be famous for表示“以某种知识技能、作品或特征而出名”
be famous as则表示“以某种身份而出名”
Einstein was famous for his Theory of Relativity. 爱因斯坦以他的相对论而出名。
Einstein was famous as a great scientist.爱因斯坦以一位伟大的科学家而著称。
2) 当主语是地点名词
be famous for表示“以某种特产而出名”
be famous as则表示“以什么样的产地或地方闻名”
The area is famous for its green tea.这个地区以绿茶而出名。
The area is famous as a great tea-producing place.这个地区以绿茶产地而出名。
3)当主语是事物名词
be famous for表示“以其内容、特征、价值等而被人所知”
be famous as则表示“以某种形式而出名”
This grammar book is famous for its practical usage.这本语法书以其实用性而为人所知。
This book is famous as a reference book.这是一本有用的参考书。
注意：be famous for后的介词宾语是主语所属内容，而be famous as后的介词宾语与主语是同位成分。例如：
Einstein was famous as a great scientist. 可说成：Einstein was a great scientist.
2.kind, sort和type的区别
kind指性质相同，且有极相似之物质，在分类中可作为一类者。
What kind of cake do you like best?你最喜欢哪一种饼？
sort 可与kind互换使用，但较为含混，有时只表示大概此种而已。Sort有时有轻蔑的意味，相反kind 要庄重得多。
He makes friends with all sorts of people.他同各种各样的人交朋友。
type则指型，类型，比较具体，肯定等，而kind比较笼统，模糊。
Men of his type are not to be trusted.像他那种类型的人不可信赖。
3.As in China, the weather is different from area to area. 同中国的情况一样，加拿大的气候也随着地区的不同而不同。
本句相当于一个省略的方式状语从句，相当于“As it is in China, …”。as用作连词，后面接从句，意思是“正如；和……一样”。例：
1）As is the last experiment，he got the same result this time.正如上次的实验一样，他这次获得了同样的结果。
2)As in your country, we grow wheat in the north and rice in the south.正如你们国家的情况一样，我们在北方种小麦，南方种玉米。
4.A lot of people can’t tell difference between an American accent and a Canadian accent. 很多人区别不了美国英语口音与加拿大英语口音。
tell the difference between 判别……的区别，tell在这里意为“判别，区分”再如：
The twin brothers arc very much alike. People can’t tell one from the other．孪生兄弟长得很相似，人们简直没法区分他们两个人。
Young as he is, he can tell right from wrong．尽管他还年轻，但他能辨别对错。
the difference between …指的是两者之间的区别；the difference in…指的是在某些方面的区别。如：
What’s the difference in temperature between day and night? 白天和夜间的温差是多大？
Coins have some differences in size, weight, shape and metal.硬币的差别体现在其尺寸、重量、形状和质地上。
5. We fill our cars with “gas”…,
fill…with…, “将……装满……”或“使……充满……”，如：
Jack filled his pockets with chestnuts.杰克将口袋装栗子。
fill with有“充满……”之意，是不及物动词，如：
Her eyes filled with tears. 他的两眼充满泪水。比较：
Tears filled her eyes泪水充满了她的两眼。
The room filled with heavy smoke．满屋浓烟。比较：
The heavy smoke filled the room. 浓烟满屋。
be filled with与be full of的区别：
be filled with为系表结构，如：
The young man is filled with joy. 那青年内心充满喜悦。
full of是短语形容词，含义与filled with相近，可充当状语、定语（后置）或表语。如：
Crusoe stared at the footprint, full of fear．克鲁索盯着那个脚印，满怀恐惧。（状语）
He received several baskets full of cards, letters and telegrams of congratulations．他收到了满满几篮子表示祝贺的卡片、贺信和贺电。（定语）
