Shopping课堂教学实录

教材内容分析

本 单元的中心话题是“购物”，所有的对话、课文及练习都是围绕这一话题展开的。我们要能熟练运用有关“挑选物品、询问价格、做出决定”的购物交际用语，同时 还得学会通过互联网进行购物的方法和技巧。“ on-line”给我们提供了典型的范例。本单元着重讲述了过去完成时的基本概念、构成以及它的肯定、否定和疑问句式及其简略答语，区别了so that和so…that…的不同用法。结合自己的实际情况，参考Lesson 56，进行英文日记的写作训练，也可以写一篇自己经历过的shopping活动。

本单元重点例句及相关知识讲解

1. Are you excited about going to Beijing?  去北京你很激动吗？

2. You’d better try them on first. 你最好先穿上试一试。

句中try on的意思是“穿上（戴上）试一试”。如try on 的宾语是名词时，名词可放在try on后面，也可放在try 与on之间。如：

I went to the tailor’s shop to try on my new suit. 我到裁缝店去试新做的西服。

I went to the tailor’s shop to try my new suit on. 我到裁缝店去试新做的西服

注：如try on的宾语是代词，代词一般要放在try与on之间。如：

She was trying on a new hat. (She was trying it on.) 她在试戴一顶新帽子。

3. Even though they’re a little expensive, I’ll take them. 即使鞋有点儿贵，我也将买它们。

(1)句中even though相当于even if，意思是“纵使；即使……也”。常引导让步状语从句：

I’ll help you, even if I don’t sleep for a night. 即使我一夜不睡觉，也还要帮助你。

even if ,even though还可用于虚拟语气，意思是“即使”，引导从句。如：

Even if he were here, he could not solve the problem at once, too. 即使他在这里，他也不能立即解决这个问题。（事实上他没有在这里。）

Even though she had been very busy, she would have helped us. 即使当时她很忙，她还是会帮助我们的。（事实上她当时并不十分忙，故帮助了我们）。

(2) expensive与high, cheap与low

这四个词在谈论到价格的高低时，要注意使用。expensive与high涉及到价格“高”，而cheap 与low涉及到价格“低”。

l)expensive昂贵的，花钱多的。这个单词若谈到“价格高，货贵”时，其主语不能是价格，必须是货物、物品本身。如：

This watch is expensive. 这只表很贵。

These glass-products are not expensive. 这些玻璃制品不是很值钱。

注意：cheap表示“价廉”，“便宜的”，其主语也不能是价格，必须是物品本身。如：

The cheap table was bought from him.  这张便宜的桌子是他卖给我们的。

This cloth doll is very cheap. 这只布娃娃很便宜。

2）high在表示价格时，含义是“高”，low在表示价格时，含义是“低”，这两个词不能用于物品本身，只能用在价格上。如：

The price of this watch is very high.  这只表的价格太高了。

The price of this book is not low for me. 这本书的价格对我来说是不低。

下面我们试看几个句子的正误对照：

The price of this computer is expensive.

(上句宜改为：This computer is expensive. 或The price of this computer is high. )

The price of this pen is not cheap for him to buy.

(上句宜改为：This pen is not cheap for him to buy. 或 The price of this pen is not low for him. )
4. shopping online（互联）网上或在线购物

5. She wanted to take pictures of this trip.

take pictures of this trip在旅游中照相

6. As she lives out in the country, there is no place to buy a very good camera.

因为她远在乡下居住，那儿没有能买到很好相机的地方。

* 句中as 是连词，作“由于，因为”解，引导原因状语从句。Because，since，as，for都是说明原因的接续词，because语气最强，表示理由充 分，有必然的因果关系，其次是since，表示一种间接或附带的原因，再其次是as、for，只是说明一下，关系是松弛的。如：

Everybody likes Tom, as he is kind and honest. Yesterday, we stayed at home because it rained. Someone invited him to dinner. He replied, “As I am ill, I won’t go out”. After he had hung up, he smiled, “I can’t see anything for the fog in fact”. I said, “Since you insist, I have to cook for you ”.

*句中to buy a very good camera是动词不定式短语作定语，修饰no place。

7. She decided to buy a digital camera online so that it could be sent to her.

她决定在网上订购一个数码相机，那样便可以邮寄给她。

句中so that意思是“以便，为了 ”，常常引导结果状语从句。“so (such) …that”引导结果状语从句，作“这么……，以至”或“所以”解，so接形容词、副词或分词，而such则接名词。如：

Wan Jun does exercises everyday so that she could run fast.

万军每天做练习，以便能跑得快。

Wan Jun was such a fast runner that he could almost catch up with a deer. =Wan Jun ran so fast that he could almost catch up with a deer.

万军跑得这么的快，以至于他的速度几乎能赶上鹿。

8. She had searched the Internet for two hours…

had searched 是过去完成时。

过去完成时的构成：过去完成时由“助动词had（通用于各种人称和数）+过去分词构成。

过去完成时的用法：过去完成时表示在过去某一时间或动作之前已经发生或完成了的动作。它表示动作发生的时间是“过去的过去”。用by、before等构成的短语。
9. Mr Sato looked at the ad.

ad是缩短词，也可写成advertisement，常见的缩短词还有：dormitory — dorm（宿舍）, popular — pop（流行音乐）, refrigerator — fridge（冰箱）等。

10. Then he found ads for other cameras as well.

句中as well意思是“亦；也；又；同样”。as well as 引导比较状语从句，意思是“和……做得同样好；和……一样”，as well as里的well是副词，作“好”解。

11. …all the information about different kinds of cameras… (责任编辑：admin)
