人教版高中英语必修一Unit4NaturalDisasters知识点梳理单选题1、Try to avoid such things ________will do you harm, unless you don't care about the rumors from all directions. A．thatB．asC．whichD．as that答案：B考查定语从句。

句意：除非你不在乎四面八方的谣言，否则尽量避免那些对你有害的事情。

在定语从句中缺少主语，且先行词things被such修饰，所以应用关系代词as。

故选B。

2、Peter can be really difficult at times ________ he’s a nice person in general.A．even ifB．as thoughC．as ifD．if only答案：A考查状语从句。

句意：彼得有时真的很难缠，即使一般情况下他是一个很好的人。

A. even if即使，尽管； B. as though似乎，好像； C. as if似乎，好像； D. if only要是...就好了。

空前表示Peter有时候很难缠；空后句子表示他通常情况都是很好很和善的人，前后有转折关系，只有A项even if可以引导让步状语从句，符合题意。

故选A项。

3、A sport with a broom on ice ________ requires bowling ________ makes curling one of the most unique sports out there.A．that … precisionB．that … diversityC．/ … precisionD．/ … diversity答案：A考查定语从句和名词词义辨析。

定语从句(The Attributive Clause)(二)概念：在复合句中修饰某一名词或代词的从句，叫定语从句。

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词who, whom, whose, that, which 和关系副词when, where, why等。

一、关系代词who, whom, whose, that, which的用法1、当先行词是人，关系代词作主语时，我们只能用who/ that，且不能省略。

例如：This is the man who/that helped me.2、当先行词是人，关系代词作宾语时，我们只能用whom/ that / who，可以省略。

例如：The doctor (whom/ that / who) you are looking for is in the room.3、当先行词是物时，不论其作主语、宾语，我们都用that/which,当其作主语时，不能省略；当其作宾语时，可以省略。

例如：1) A plane is a machine that/which can fly.2) The noodles (that/which ) I cooked were good.4、当先行词是人或物时,我们用whose来代替my/his/her/its/their。

例如：Do you know the man whose name is Mr. Smith?注：关系代词在从句中作介词宾语时只能用whom, which，whose，可以和介词一起放在先行词和从句之间。

例如：1) The man whom/that my teacher is talking with is my father.→The man with whom my teacher is talking is my father.2) The room that/which I live in is good.→The room in which I live is good.3) The man whose department I once worked in was Mr King.→The man in whose department I once worked was Mr King.但含有介词的短语动词一般不能拆开，介词仍放在有关动词的后面。

四、知能提升（一）知识讲解【认知讲解】● 教材原句呈现I’ve included some photos which will help you picture the places I talk about.The only possessions I could see were one broom, a few tin plates and cups and a couple of jars.对比分析第一个句子中的which引导的定语从句修饰前面的photos，而后面的I talk about也是一个定语从句，只不过是省略了引导词that。

第二个句子中的I could see也是一个定语从句，其前也是省略了关系代词that。

【重、难点】I. 概念：（1）定语从句：在主从复合句中用作定语的从句叫定语从句。

定语从句一般紧接在先行词后面。

（2）先行词：被定语从句修饰的成分。

先行词可以为一个名词、代词，有时候还可是一个短语或整个主句。

（3）关系词：引导定语从句的词叫关系词，分为关系代词和关系副词。

关系词的作用：1）引导定语从句，连接主句和从句，相当于一个连词；2）必在从句中作某种句子成分（可作主语，宾语，表语，定语，状语）常用的关系代词：that（在从句中作主语，宾语，表语；可指人或物）which（在从句中作主语，宾语，表语或定语；只可指物）who（主格，在从句中作主语，在口语或非正式用法中可作宾语；只可指人）whom（宾格，在从句中作宾语；只可指人）whose（属格，在从句中作定语，可指人或物）as（在从句中作主语，宾语，表语；可指人或物，通常指代事物）；常用的关系副词（在从句中只作状语）：when（时间状语），why（原因状语），where（地点状语）II. 几个关系代词的基本用法：一）that:①可指人或物；②在定语从句中作主语，宾语，表语（指人时，相当于who或whom；指物时，相当于which）；③一般不用于非限制性定语从句；④不可置于介词后作宾语。
