1、重点语法精析解码书面表达Unit 5 Travelling abroad Period 3Grammar&Writing 课件（人教新课标选修7，课标通用）定语从句(二)定语从句的分类定语从句根据其与先行词的密切程度可分为限制性定语从句与非限制性定语从句。一、重点语法精析解码书面表达1限制性定语从句限制性定语从句与先行词关系密切，从句是整个句子不可缺少的部分，从句与主句之间不用逗号隔开。如果去掉它，句子的意思就不完整或不明确。译成汉语时，一般先译定语从句，再译先行词。I dont like people who always think of themselves.我不喜欢那些总是为他们自己着
2、想的人。重点语法精析解码书面表达2非限制性定语从句非限定性定语从句起补充说明作用，缺少也不会影响全句的理解，在非限定性定语从句的前面往往有逗号隔开，如将非限定性定语从句放在句子中间，前后都需要用逗号隔开。The sun,which rises in the east,gives us heat and light.太阳从东方升起，带给我们光和热。重点语法精析解码书面表达(1)引导非限定性定语从句的关系代词：重点语法精析解码书面表达(2)关系代词as和which 两者均可引导非限制性定语从句，有时可以互换，但下列情况多用as。关系代词引导的定语从句居句首时。在such.as.，the same.
3、as.，as.as.，as many/much as.等结构中，as不能用which代替。当从句和主句语义一致时，用as，反之用which。as在从句中作主语时，后面常接行为动词的被动语态，如be known，be said，be reported等，如从句中行为动词是主动语态，一般要用which作主语。重点语法精析解码书面表达He was late again,as/which we had expected.As we had expected,he was late again.正如我们所料，他又迟到了。/他又迟到了这是我们早就料到的。The young man cheated his
4、friend of much money,which was disgraceful.那年轻人诈骗了他朋友许多钱财，这是不光彩的。(不用as)I live in the same building as he(does)我和他住在同一座大楼里。He knows as many people as are present at the meeting.他认识所有到会的人。重点语法精析解码书面表达(3)应注意的问题大多数关系代词和关系副词均可引导限制性和非限制性定语从句，但that 一般不用来引导非限制性定语从句。误：Fang passed her exam，that surprised me a
5、 great deal.正：Fang passed her exam,which surprised me a great deal.重点语法精析解码书面表达使用非限制性定语从句时，先行词指人，关系代词主格用who，宾格用whom，作定语用whose；先行词表时间或地点且在从句中作时间状语或地点状语时，可用when，where来引导。Last Sunday I reached Shantou,where I met Chai.上星期我到达汕头，在那里碰到了钗。Linmeimei died in the night,when she was lonely.林妹妹死于晚上，那时她是孤寂的。重点语法
6、精析解码书面表达关系代词的省略情况，不同关系代词在限制性定语从句作宾语时可以省略去，而非限制性定语从句中，所有的关系词均不可省略。This is the pen(which/that)I bought yesterday.这是我昨天买的笔。The pen,which I bought yesterday，has been given to my friend.我昨天买的笔，现已送给我的朋友了。重点语法精析解码书面表达二、特殊的先行词1one of the 复数名词”后面定语从句中谓语单复数情况这一结构后面的定语从句的谓语动词通常用复数形式，即与定语从句前面的复数名词在数上保持一致。如果one
7、of 复数名词这一结构前面带有the only，the very之类的限定语，后面定语从句的谓语动词则要用单数形式，这是因为定语从句在意义上修饰的是the.one而不是那个复数名词。如：重点语法精析解码书面表达He is the only one of the teachers who knows French in our school.(修饰the only one)He is one of the teachers who know French in our school.(修饰the teachers)This is the only one of the rooms that is
8、 free now.(修饰the only one)This is one of the rooms that are free now.(修饰rooms)重点语法精析解码书面表达2先行词是the way时，其后的定语从句的关系词当way作先行词并在定语从句中作状语时，关系词用that或in which或省略。I like the way in which/(that)the teacher gives his lessons.我喜欢这位老师的授课方式。当way作先行词并在定语从句中作主语、宾语时，用that或which。作宾语时可将关系词省略。The way which/that/不填 he
9、 told us was practical.他告诉我们的这个方法很实用。重点语法精析解码书面表达3当先行词为case，condition，situation，position，point，stage等名词，表示情况、方面、处境时，如果关系词在从句中作状语，用关系副词where。但先行词是occasion时，用关系副词when。I have reached a point in my life where I am supposed to make decisions of my own.我已经到了应该自己作决定的那个人生阶段。I can remember very few occasions
10、 when he had to cancel because of ill health.我记得他因健康不佳而被迫取消的情况绝无仅有。重点语法精析解码书面表达三、定语从句和同位语从句的区别1意义同位语从句是用于说明所修饰名词的具体内容的，它与被修饰词语通常可以划等号；而定语从句是限制所修饰名词的，它的作用是将所修饰的名词与其他类似的东西区别开来。We are glad at the news that he will come.听到他要来这个消息我们很高兴。(news的内容就是that he will come，故that引导的是同位语从句)重点语法精析解码书面表达 We are glad a
11、t the news that he told us.听到他告诉我们的这个消息我们很高兴。(that从句是限制the news的内容的，即我们高兴只是因为他告诉的这个news而不是其他的news，故that从句为定语从句)2引导词what,how,if,whatever 等可引导名词性从句，但不引导定语从句。that引导同位语从句时，不充当句子成分，而引导定语从句时，它作为关系代词，要么充当定语从句的主语，要么充当定语从句的宾语。如上例 that he told us中的that就充当told的宾语。重点语法精析解码书面表达3被修饰词语同位语从句所修饰的名词比较有限，通常有hope,wish,
12、idea,news,fact,promise,opinion,suggestion,truth等，而定语从句所修饰的名词则非常广泛。另外，when和where 引导定语从句时，通常只修饰表示时间和地点的名词，而它们引导同位语从句时却不一定；又如why引导定语从句，它通常只修饰名词the reason，而它引导同位语从句时不一定。I have no idea when they will come.我不知道他们什么时候来。(同位语从句)重点语法精析解码书面表达Ill never forget the days when I lived there.我永远不会忘记我住在那儿的日子。(定语从句)We
13、 dont understand the problem why this is the best choice.我们不明白这个问题，为什么这是最好的选择。(同位语从句)The reason why he didnt come to the meeting is that he is ill.他未能来开会，原因是他生病了。(定语从句)重点语法精析解码书面表达【感悟高考】1A lot of language learning，_has been discovered，is happening in the first year of life，so parents should talk muc
