二、本单元课文难点讲解
1. Are you excited about going to Beijing?
Excited兴奋；激动的，这个形容词是动词excite的过去分词，类似的词还有：delighted, disappointed, tired, frightened, puzzled, pleased, surprised, satisfied, worried等等。
2. You'd better try them on first.
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.
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.)
3. Even though they're a little expensive, I'll take them.
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.
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）。
4. She decided to buy a digital camera online so that it could be sent to her.
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：
Tom does exercises everyday so that she could run fast.
Tom was such a fast runner that he could almost catch up with a deer. = Tom ran so fast that he could almost catch up with a deer.
5. 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。
6. 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。
7. 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。
8. …all the information about different kinds of cameras…
different kinds of 不同种类的，表达"……这（几）种"可用以下组合：
this kind of + 名词原形 + 动词单数
these kinds of 名词原形/名词复数 + 动词复数
名词复数 + of this kind + 动词复数
三、本单元词语辨析
1．think, think about, think of
(1) think 单独使用时表示"思考"， 接that 宾语从句时意为"认为"，"觉得"。
如：1) I am thinking how to work out the problem.
2) I think she is a good student.
当宾语从句含有否定概念时，通常形式上否定think ，但意义上却是否定宾语从句。
如：1) I don't think he can come.
2) I don't think it will be windy.
(2)think about 可接一个名词，动词-ing 形式或由疑问词引导的不定式或宾语从句，意思是"考虑……"。
如：1) I have thought about it for a long time.
2) Please think about how to tell her the bad news.
3) I am thinking about going to Shanghai for my holiday.
(3)think of 表示"认为"， 一般用于疑问句中，与what 连用。
如： What do you think of the TV play? = How do you like the TV play?
2. big, large, great
上述形容词都表示"大"，但侧重点及程度不同。
(1) big指具体事物的大小，强调比正常形体的标准大，既可用在普通场合， 也可用在正式场合。它可用来指人的身材高大或"长大了"，还可表示"伟大"，"重要"之意。如：
1) Can you lift up this big stone?
2) On the last day I made a big decision.
(2) large特别强调远远超过标准的大，指体积、面积、容积、数量之大。如：
1) A whale is a large animal.
2) A large crowd collected at the gate of the theatre.
3) This coat is too large for me.
(3) great除了表示数量体积之大外，又指抽象的程度，意味着伟大性，重要性， 优越性；常用于抽象或无形的东西；用于有形的东西时，常带有"伟大"，"大得令人吃惊"等意思，含有一定的感情色彩。如：
1) China is a great country with a long history.
2) He was one of the greatest scientists .
3. cost, take, spend, pay
(1) cost表示"花钱"，花费，付出（只能用于钱、精力、生命等；主语必须是物。）
The book cost me five yuan.
(2) take的主语是动词不定式, 通常用it做形式主语。
It took me five yuan to buy the book..
(3) spend，在主动语句中主语是人
I spent five yuan on (for) the book.或I spent five yuan (in) buying the book.
(4) pay的主语是人。
I paid five yuan for the book.
4． Expensive, high, cheap, 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买给我们的。
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.
(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.
(宜改为：This pen is not cheap for him to buy. 或 The price of this pen is not low for him. )
四、本单元语法重点
过去完成时态（一）
过去完成时表示过去某一时间或动作之前已完成的动作
结构：助动词had + 动词的过去分词

eg. By the end of last term, we had learned a thousand English words.

2.表示过去某个时间之前发生的动作或状态, 一直延续到这一过去时刻,或还将继续下去.
