高三英语一轮复习---定语从句讲义

高考英语复习备考：名词性从句和定语从句讲练PART 1 考点剖析-名词性从句考点一：考查what引导名词性从句例1．______ annoyed me last night was the noise of the firecrackers from the neighborhood area till midnight.【答案】What【详解】考查名词性从句。

句意：昨晚使我恼火的（事）是从附近街区传来的一直持续到午夜的爆竹声。

句子分析可知，“___ annoyed me last night”为名词性从句作主语，设空处在从句中作主语，表示“……事”，用连接代词what 引导；设空处位于句首，首字母大写。

故填What。

考点二：考查that引导名词性从句例2．When we come across such factual differences, we shouldn’t rush to the conclusion ________ one of the news reports gives false information.【答案】that【详解】考查同位语从句。

句意：当我们遇到这样的事实差异时，我们不应该急于得出其中一篇新闻报道提供了虚假信息的结论。

引导同位语从句，说明conclusion的内容，从句不缺少成分，句意完整，故用that引导。

故填that。

考点三：考查-ever引导名词性从句例3．Every employee needs to find their unique value contribution that makes them stand out in ________ is their field of employment.【答案】whatever【详解】考查名词性从句。

句意：每个员工都需要找到自己独特的价值贡献，使他们在自己的就业领域脱颖而出。

分析句子可知，设空处位于介词in后，在句中引导宾语从句，从句中缺主语，结合句意可知，此处表示物，应用whatever引导。

定语从句知识点梳理1.定语从句：定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。

2.关系词：引导定语从句的关联词称为关系词，关系词有关系代词和关系副词。

关系代词有that, which, who, whom, whose, as等；关系副词有where, when, why等。

关系词常有3个作用：1.引导定语从句2.代替先行词3.在定语从句中担当一个成分。

3. 先行词：被定语从句修饰的名词、代词称为先行词。

一、关系词的用法(一)关系代词who, whom, whose, that, which（在句中作主语、宾语或定语）关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。

关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。

1）who, whom, that这些词代替的先行词是人的名词或代词，在从句中所起作用如下：Is he the man who/that wants to see you?他就是你想见的人吗？（who/that在从句中作主语）He is the man whom/ that I saw yesterday.他就是我昨天见的那个人。

（whom/that在从句中作宾语）2) Whose 用来指人或物，(只用作定语, 若指物，它还可以同of which互换）, 如：They rushed over to help the man whose car had broken down.Please pass me the book whose (of which) cover is green.3）which, that它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：A prosperity which / that had never been seen before appears in the countryside.The package (which / that) you are carrying is about to come unwrapped.4) asAs用于先行词前有as, so, such, the same修饰的限制性定语从句.You can take as many books as you need.(二) 关系副词when, where, why（在句中作状语）1. when指时间，在定语从句中做时间状语(1) I still remember the day when I first came to the school.(2) The time when we got together finally came.2. where指地点，在定语从句中做地点状语(1) Shanghai is the city where I was born.(2) The house where I lived ten years ago has been pulled down.3. why指原因，在定语从句中做原因状语(1) Please tell me the reason why you missed the plane.(2) I don’t know the reason why he looks unhappy today.注意：关系副词引导的从句可以由“介词+关系代词”引导的从句替换(1) The reason why/ for which he refused the invitation is not clear,(2) From the year when/in which he was going to school he began to know what he wanted when hegrew up.注意：介词+关系代词引导的定语从句关系代词在定语从句中做介词宾语时1. 含有介词的动词短语一般不拆开使用，如：look for, look after, take care of等(1) This is the watch which/that I am looking for. (T)(2) This is the watch for which I am looking. (F)2. 若介词放在关系代词前，关系代词指人时用whom，不可用who或者that；指物时用which，不能用that；关系代词是所有格时用whose(1) The man with whom you talked is my friend. (T)(2) The man with that you talked is my friend. (F)3. “介词+关系代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词(1) He loved his parents deeply, both of whom are very kind to him.(2) In the basket there are quite many apples, some of which have gone bad.4. 介词后面的关系词不能省略。

长难句分析讲义：定语从句的作用原句Their recovery has been so successful that the U.S. Fish and Wildlife Service has twice attempted to delist grizzlies, which would loosen legal protections and allow them to be hunted.（2023年全国甲卷阅读理解D篇）Their recovery has been so successful它们的复苏是如此成功that the U.S. Fish and Wildlife Service has twice attempted to delist grizzlies,以至于美国鱼类和野生动物管理局曾两次试图将灰熊从名录中除名“如此……以至于”传递的就是因果逻辑，因为“如此”的事实表现非常明显，所以导致或促成了“以至于”后面的另一个事实。

这个句子里的情况就是，灰熊之前濒临灭绝，于是政府把它加入了野生动物保护名录。

但是随后一段时间里，受到保护的灰熊数量激增，复苏的状况非常好，所以政府要从保护名录中将灰熊除名。

“list 列表、列出”，加上动词否定前缀de-，就是“delist 从列表里去除”这个相反的动作。

which would loosen legal protections and allow them to be hunted.这会放松法律的保护并且允许它们被猎杀“so … that”结构后看到的是which引导的定语从句。

结合这个句子，我们来重点谈谈定语从句存在的意义。

说到定语从句的作用，每个人的脑海里都会立刻闪过“修饰限定”这四个大字，但是事实真的如此吗？以下面的三个句子为例，在不考虑高考英语考试要求、不考虑高中英语教学的情况下，请问：哪个版本在你看来更好一些？Yesterday he bought me a book. I like it very much. 简单句I like the book bought by him yesterday. 非谓语动词补充I like the book that he bought me yesterday. 定语从句补充这三个句子在句意表达上没有任何区别。

从句简单句：一套主谓结构复合句：多套主谓结构从句体系：一．名词性从句连接词：（一）宾语从句把句子当作名词（n.）放在宾语的位置上，这个句子叫宾语从句Eg: Lucy studies English.I saw Lucy studies English.Eg: I know the fact.I know that she is right.例句：1.I saw that the rabbit ate a carrot.2.I wonder whether the rabbit is the carrot.3.I saw who ate the carrot.4.I saw what the carrot ate.5.Tell me whose house is it.6.He asked me which shirt I like best.7.No one knows who was waiting for him.8.I saw when the rabbit ate the carrot.9.I saw how the rabbit ate the carrot.10.I know why he came to the class late.11.I don't know where the rabbit ate the carrot..（二）主语从句把句子当作名词，放在主语的位置上，这个句子叫主语从句Eg：The fact is obvious.That Lucy studies English is obvious.例句：1.Whether the rabbit ate carrots is obvious.2.It is obvious that the rabbit ate the carrot.3.It is obvious who ate the carrot.4.It is obvious whom Tom was waiting for.5.It is obvious whose house is it.6.It is obvious which shirt I like best.7.It is obvious when the rabbit ate the carrot.8.It is obvious how the rabbit ate the carrot.9.It is obvious why he came to the class late.10.It is obvious where the rabbit ate the carrot..（三）表语从句把句子当作名词，放在表语的位置上，这个句子叫表语从句例句：1.The problem is that the rabbit is hungry.2.The reason is that there’s more carrot.3.The question is whether the rabbit is hungry.4.The question is what the rabbit should eat.5.The question is where/when/how/rabbit ate the carrot.6.The question is when we get a pay rise.（四）同位语从句把句子当作名词，放在同位语的位置上，这个句子叫同位语从句同位语：解释说明名词的内容或实质的成分。

2023全国甲卷长难句整理分析A【定语从句】1.Head Chef David Thompson, who received a Michelin star for his Londonbased Thai restaurant of the same name, opened this branch in the Metropolitan Hotel in 2010.主厨大卫 ·汤普森因其在伦敦的泰国餐厅同名而获得米其林星级，他于2010年在大都会酒店开设了这家分店。

句子1是who引导的非限制性定语从句，who指代前一句中的David Thompson并在从句中充当主语。

Who从句在本句子中起到补充说明的作用，说明David Thompson曾因其在伦敦的泰国餐厅同名而获得米其林星级。

2.This place is good for a candlelit dinner or a work meeting with colleagues who appreciate fine food.这个地方很适合烛光晚餐或者和喜欢美食的同事开工作会议。

句子2是who引导的限制性定语从句，who指代前面主句中的 colleagues并在从句中充当主语，“colleagues who appreciate fine food”可译为“喜欢美食的同事”。

3.The best table in this twostory colonial Thai home offers a window right into the kitchen, where you can see chef Gaggan and his staff in action. Culinary theater at its best.在这个两层的殖民地泰国家庭最好的桌子提供了一个窗口直接进入厨房，在那里你可以看到厨师加根和他的工作人员的行动。
