必修一Unit5 定语从句复习教学设计
引入 :
定语从句在历年高考试题中都有体现,掌握这一语法内容显得尤其重要。 教学目标: 1.知识目标:使学生掌握关系代词与关系副词引导的定语从句,掌握as和which引导的非限制性定语从句的用法;“介词+关系代词”引导的定语从句;区分限制性定语从句与非限制性定语从句。
2.能力目标:培养学生如何确定关系代词和关系副词的选用以及一些解题技巧。 3.情感目标:培养学生竞争意识和自主学习的能力,培养学生学习英语的热情。 教学重点:
关系代词与关系副词引导的定语从句。 教学难点:
“介词+关系代词”引导的定语从句。 教学方法:总结归纳法 教学用具:多媒体 教学过程:
(一)定义及相关术语 关系代词与关系副词 1.定语从句:修饰某一名词或代词的从句叫定语从句。定语从句一般紧跟在它所修饰的先行词之后。
The man who is shaking hands with my father is a policeman. 2.先行词:被定语从句修饰的词叫先行词。
3.关系词:引导定语从句的词叫关系词。关系词有关系代词和关系副词 关系代词有: that, which, who, whom, whose,as 关系副词有: when, where, why 关系词通常有下列三个作用:
A.引导定语从句;B.代替先行词;C.在定语从句中担当一个成分。 (二)、关系代词that和which在很多情况下可以互换,但下列情况只用that: (通过例句总结归纳得出下列结论)
1.先行词是all,everything,nothing,anything,something,much,little,none等不定代词,引导定语从句用that .
2.先行词被形容词最高级或序数词修饰时,引导定语从句用that 。
3.先行词被any,some,no,much,few,little,every,all,very,only,last修饰时,引导定语从句用that 。
4.先行词中既有人又有事物时,引导定语从句用that . (三)不用that,而用which,who,whom的情况 (通过探究得出结论)
1.在非限制性定语从句中,指事物用which,指人用who或whom。 2.在介词后面,指事物用which,指人用whom。 如何判断介词(小组讨论然后总结) 1、看定语从句中动词与介词的搭配 2、看定语从句中形容词与介词的搭配
3、根据先行词判断,所用的介词与先行词搭配 (四)Where 引导的定语从句
先行词是表示地点的名词或含有地点意义的抽象名词,用来引导定语从句。Where 在从句中作状语。
探究:区分where引导的定语从句和状语从句
Where前面有被修饰的地点名词时,是定语从句,否则是状语从句。 若定语从句缺主语或宾语,用which或that引导定语从句。 When 引导的定语从句
先行词是表示时间的名词,用when引导定语从句。在从句作状语。 若定语从句缺主语或宾语,用which或that引导定语从句。 why引导的定语从句
先行词是表示原因的名词,用why引导定语从句。在从句作状语。 This is the reason why ( = for which ) I didn’t come here. whose 引导的定语从句 表示所属关系 as 和 which 的区别 such + 名词 +as +从句 像、、、、、、一样的,像、、、、、、之类 the same +名词+ as +从句 和、、、、、、同类的
which 代替前面的句子,表示“这一点,这件事” as 代替前面的句子,表示“正如,好像” (五)限制性定语从句和非限制性定语从句 A.限制性定语从句形式上不用逗号“,”与主句隔开。意义上是先行词不可缺少的定语,如删除,主句则失去意义或意思表达不完整。
The teacher told me that Tom was the only person that I could depend on. China is a country which has a long history.
B.非限制性定语从句只是对先行词的补充说明,用逗号“,”与主句隔开。如删除,主句仍能表达完整的意思。译法上译成先行词的定语“...的” 通常译成主句的并列句。
His mother, who loves him very much, is strict with him. China, which was founded in 1949, is becoming more and more powerful. 当堂思维训练:
1. The boy ______ composition won the first prize is the youngest in the group. A. who B. whose C. that D. which
2. The weather turned out to be very good, ______ was more than we could expect. A. what B. which C. that D. it
3. I shall never forget the years _______ I lived in the country with the farmers, ______has a good effect on my life.
A. that, which B. when, which C. which, that D. when, who
4. Is this book _____ you want to borrow from the library? A. that B. which C. the one D. /
5. Such a book ______ you showed me is difficult to understand. A. that B. which C. as D. like
6. This is the store ______ we visited the famous shop assistants. A. where B. there C. that D. which
小结:
1、这节课你收获了什么内容?完成了教学目标,掌握了定语从句用法。 2.你学到了什么解题方法?
通过以上学习学生讨论总结解题要领和选择引导词总原则。
解题要领:根据定语从句中所缺成分来确定是用关系代词还是关系副词,决不要因为先行词是时间名词就用when, 是地点名词就用where. 选择引导词的总原则:将先行词放入定语从句中,看其充当的成分,如果充当主、宾、表,用关系代词;如果充当状语,用关系副词。根据其在从句中的搭配选择相应的介词+which。
课下作业:见课下巩固练习。 板书
定语从句分为限制性定语从句和非限制性定语从句 关系词有关系代词和关系副词
关系代词有: that, which, who, whom, whose,as 关系副词有: when, where, why
