初三下学期 Unit 17 The missing necklace

语法：定语从句（The Attributive Clause）

　　在复合句中，修饰某一名词或代词的从句叫做定语从句。

【例】

　　（l）The man who lives next to us sells vegetables．

　　（2）You must do everything that I do．

　　上面两句中的man和everything是定语从句所修饰的词，叫先行词，定语从句放在先行词的后面。

　　引导定语从句的词有关系代同that，which，who（宾格whom，所有格whose）和关系副词where，when。关系代词和关系副词放在先行词和定语从句之间，起联系作用，同时又作定语从句的一个成分。

　　l）由关系代词引导的定语从句：

　　①that在从句中可作主语或宾语，指物或指人。

【例】A plane is a machine that can fly．

　　Who is the man that is reading a book over there?

　　②which在从句中可作主语或宾语，指物。

【例】They planted the trees which didnt need much water．

　　The fish which we bought were not fresh．

　　③who，whom在从句中分别作主语和宾语，指人。

【例】The boy who broke the window is called Tom．

　　Mrs Read is the person to whom you should write．

　　2）由关系副词引导的定语从句：

　　①when指时间。

【例】I’ll never forget the time when we worked on the farm．

　　②where指地点。

【例】This is the house where we lived last year．

　　注：1．that和which在从句中作主语时，不能省略；作宾语时，在口语和非正式文体中经常省略。whom也常可省略。

　　2．关系代词that在定语从句中作介词的宾语时，介词不能放在它的前面，只能放在从句中有关动词的后面。

【例】The village that she lives in is twenty kilometres away．

关于第65课定语从句的教学建议

　　第65课是一段对话，通过妻子向丈夫述说有人偷了她的项链的事情。这一课的语法重点是由关系代词who, that引导的限定性定语从句。有讲解相关的知识时，可设计图文并貌的教学过程，帮助学生理解和掌握定语从句这一语法难点。

　　先给出一个小男孩Tom的图片，提供以下词汇：

　　the handsome

　　the tall

　　the strong

　　the clever

　　the naughty

用以上的词汇来描述Tom，形成如下句子：

　　综述以上的句子，who在句中指小男孩Tom，在句中作定语，它引导的句子就是定语从句。

请看以下有关定语从句的例句：

　1.The boy is Tom.  The boy has a round face.

　　The boy who is smiling is Tom.

　　　　　　(主语)

　2.The boy is in the lab. You want to talk to him.

　　The boy (whom) you want to talk to is in the lab.

　　The boy to whom you want to talk is in the lab.

　　以上例句中的who 可以用that 来代替，在定语从句中that可以指人或物，代替who，whom，which；在从句中可以作主语、宾语，但不能放在介词后作介词宾语。如：

　　This is the photo that (which) I took in Beijing last year.

　　This is the man that/who lives next door.

　　Is this the professor that you talked about yesterday? (about不能放在that前面)

定语从句练习

　　Which boy do you like better?

Answers list:

　　The boy who has a big mouth / has not shoes / has long hairs / with laughing.

　　The boy who wears a green sweater / has a plane / was hurt in his leg/ has little hairs / has big eyes.

　　The boy who has a blue bag / has a hat / has green shoes.

　　The boy who has red button / has purple shoes / is wearing a suit.

　　The boy who wears blue coat / has a red bag / has black shoes.

　　The boy who is smiling / who is naughty / has brown shoes.

课文Who stole the necklace 的教学建议

　　本单元第66课和67课的课文是一幕短剧。讲述了格林太太项链丢失后，发现是鹦鹉模仿劫犯的行为将项链取走的。教学中可考虑将这两课一起进行讲解。

　　先看展示剧情过程的一组图片，听课文的录音，熟悉课文内容。再讲解相关的词汇用法等知识。最后可根据这组图，让学生用自己的话复述课文。图片提供如下十幅：
