定语从句公开课课件
定语从句公开课的课件应该要怎么进行设计呢?下面定语从句公开课课件是小编想跟大家分享的，欢迎大家浏览。
Ⅰ、 定义
定语从句，起形容词的作用，在句中常用来修饰名词或代词。被修饰的词称为先行词,引导定语从句的词称为关系词, 关系词的作用一是放在先行词与定语从句中间起引导作用;二是在意义上代替先行词,并在从句中充当一个成分。其中关系代词：who, whom, whose, which, that, as;关系副词：when, where, why。
eg、 She is the girl who sings best of all、
The pen which my uncle gave me is missing、
He lives in a house whose windows face south、
The factory where my father works is in the east of the city、
Perhaps the day will e when people will be able to breathe clean air in cities、
Ⅱ、 关系代词
1、 先行词是人，作主语，关系代词用who, that
eg、 He is a man( ) never leaves today’s work till tomorrow、
The boy ( ) is standing there is my cousin、
2、 先行词是人，作宾语，关系代词用 whom, who, that,
eg、 Here is the man ( ) you’ve been expecting to meet、
The man ( ) you met yesterday is Mr、 Smith、
3、 先行词是物，作主语，关系代词用which, that
eg 、 The train ( ) has just left is for Guangzhou、
Children like to read books ( ) have wonderful pictures、
4、 先行词是物，作宾语，关系代词用which, that,或省略
eg、 The book ( ) you borrowed yesterday is really interesting、
The pen ( ) my uncle gave me is missing、
5、 先行词是人、物，作定语，关系代词用whose
eg、 He is the professor ( ) name was Jackson、
China, ( ) population is the largest in the world, is developing very fast、
Ⅲ、 关系副词
1、 先行词是表示时间的名词，在定从中作时间状语，关系代词用when
eg、 I can’t remember the date ( ) he went abroad、
I’ll never forget the day ( ) I joined the army、
2、 先行词是表示地点的名词，在定从中作地点状语，关系代词用where; 其中注意表示抽象概念的地点名词，如，situation、stage、degree、point等表示方面或程度时，也需用where
eg、 This is the village ( ) Uncle Wang once lived、
They have reached the point ( ) they have to separate with each other、
He’s got himself into a dangerous situation ( ) he is likely to lose control over the plane、
3、 先行词是reason，在定从中作原因状语，关系代词用why
eg、 I don’t know the reason ( ) he was late、
None of us know the reason ( ) Tom was absent from the meeting、
4、引导定语从句的关系副词也可以用“适当介词 + which”来代替。
eg、 October 1, 1949 was the day when ( = ) the People’s Republic of China was founded、
This is the factory where(= ) we worked a year ago、
I don’t believe the reason why (= ) he was late for school、
Ⅳ、 关系代词that & which的区别:
⒈ 只用that的情况
① 先行词为all, everything, anything, nothing, little, much等不定代词时。
eg、 There is nothing ( ) can prevent him from doing it、
② 先行词被any, only, few, no, very, little 等修饰时。
eg、 This is the very book ( ) I’m looking for、
③ 先行词被形容词最高级或序数词修饰时。
eg、 The first place ( ) they visited in Guilin was Elephant Trunk Hill、
This is the best film ( ) I have ever seen、
④ 先行词既有人又有物时。
eg、 He talked about things and persons ( ) they remembered in the school、
⑤ 先行词被the only, the very修饰时。
eg、 Mr、 Smith is the only foreigner ( ) he knows、
⑥ 句中已有who或which,为了避免重复时。
eg、 Who is the man ( ) is standing beside Tom?
⒉ 不能用 that的情况：
① 引导非限制性定语从句;
eg、 He had failed in the maths exam , ( ) made his father very angry、
② 介词 + 关系代词。
eg、 This is the room in( ) my father lived last year、
Ⅴ、 as引导定语从句时的、用法(as 相当于that & which)
① as引导限制性定语从句通常用于the same … as, such … as结构中。
eg、 This is the same book ( ) I lent you、
Such machines ( ) are used in our workshop are made in China、
② as引导非限制性定语从句既可放在主句之前，也可放在主句之后，位置灵活，用来修饰整个句子。通常用下列句型：as is known to all, as is said, as is reported, as is announced, as we all know, as I expect 等。
eg、 ( ) I expected, he got the first place again in this mid-term examination、
Taiwan, ( ) we all know, belongs to China、
Ⅵ、 限制性定语从句和非限制性定语从句的主要区别:
限制性定语从句: 一般紧跟在先行词后面,不用逗号把从句与先行词分隔开来。使先行词的意思十分明确,成为特定的人或物,是句子中不可缺少的成分,少了它句子就会失去意义不能成立,或意思不清楚,不能说明问题。通常译为定语。
非限制性定语从句: 通常由逗号与句子其他成分隔开。只是对先行词作进一步的说明,没有它句子仍能成立,意思仍很清楚。通常译为并列的句子。
eg、 I was the only person in our office ( ) was invited、(去掉定语从句，意思就不完整)
Tom’s father, ( ) is over sixty, still works hard day and night、(整个句子可分成两句来翻译)
Ⅶ、 分隔定语从句
即先行词与关系代词、副词之间被介词短语，同位语，谓语等分隔开来。
此种定语从句，在选择关系词时，要注意找准先行词。
eg、 There is an expression in his eyes ( )I can’t understand、
I was the only person in my office ( ) was invited to the important ball、
I suggest you choose someone I think ( ) is very kind and friendly、
