教材分析
本单元的对话主要是简单地介绍自己的表达语如：I"m…，I do及询问对方意愿What do you plan to next？和表达自己意愿及希望I plan……，I wish that…的交际用语。阅读课主要是了解电影喜剧大师查理？卓别林的生平和他的电影。本单元使用的词汇较为丰富如：direct，act，set off，appearance，bring up，honor，as if，intend。非限制性定语从句中关系代（副）词的使用，是本单元的重点语法项目。
重点知识讲解
1.be known for，be known as和be known tobe known for=be famous for意为“因……而出名”，介词for表示原因。
Guilin is known for its beautiful scenery.
be known as=be famous as意为“作为……而出名”，介词as指主语的身份或名称。
Mr.Zhang is known as an English teacher.
be known to意为“为（某人）所知或熟悉”，介词to后接人。
As is known to all，she is always ready to help others.众所周知，她总是乐于助人。
2.search，search for和in（one"s）search for/ofsearch=try to find by looking，意为“搜寻”、“搜查”。search的宾语一般是被搜查的人或某一场所，而不是所要寻找的东西。
The policeman searched the thief to see what he had in his pockets.那个警察对小偷搜身，看他口袋里有什么东西。
search for相当于look for。search for的宾语一般为要找的东西，而不是被搜查的人或场所。
The villagers were searching for the missing boy.村民们正在寻找那失踪的男孩。
注意：I search a place for a person=search a person in a place，意为“在某地搜寻某人”。
in（one"s）search for和in search of都意为“寻找”、“寻求”，在句中既可作状语，也可作表语。注意两个短语介词的搭配，如果名词search前带有限定词a，the或one"s，后面一般用介词for，如果search前不带限定词，后面一般用介词of。
The husband joined the wife in her search for the unknown element（元素）。
Some birds fly south in search of winter sun.

He bought me a pen.（=He bought a pen for me.）
单宾语动词后只接一个宾语，如果接指人的宾语则需用介词“to”来连接。如：He explained the matter to me.（正）=He explained to me the matter.
He explained me the matter.（误）
