19、earn re abut the attributive lause Predures Leading in: Reading and disvering Read the passages and underline all the attributive lauses Tas 1: Revieing the attributive lause 学习定语从句的几个问题 1、 掌握以上关系代词、关系副词的含义及使用时，要特别注意以下几点： 1) 指物时宜用 that 的情况： a 当先行词为 all, uh, little, fe, nne, sething, anthing, everthi
20、ng, nthing 等不定代词时。All that an be dne has been dne b 当先行词既指人又指物时。 He spe f the en and the thing (that) he had seen abrad 当先行词被序数词或形容词的最高级修饰时。 This is ne f the best fils that I have ever seen d 当先行词被 the ver, the nl, the last, an, ever 等修饰时。 This is ne f the ver b that I a ling fr e 当先行词是疑问词 h, hat, h
21、ih 时。 h that has suh a he desnt lve it? f 关系代词在从句中作表语。 ar is n lnger the girl that she used t be 2) 关系代词 as 和hih都能引导非限定性定语从句代表整个句子的内容，as 引导的从句可位于句首或句末，hih引导的定语从句则不能位于句首。 hih u n, he is a gd an () As u n, he is a gd an () 3)关系副词hen, here, h其含义相当于n hih, in hih fr hih等，可以互换： The da hen /n hih I et hi f
22、irst as a 1st I dnt n the reasn h /fr hih he didnt e 47)hse指物时，可以与f hih等结构互换，但应注意与冠词的位置关系： This is the b the ver f hih / f hih the ver / hse ver is blue )有时可用代替关系副词。在口语中常省略。 This is the reasn (h / fr hih / that) he ae late 6)先行词是专有名词、整个句子或世界上独一无二的物质名词时，一般用非限定性定语从句修饰。The sun, hih gives us light and h
23、eat, is ver big 7)在先行词和定语从句之间有无逗号有时会引起名义的变化： He said nthing that ade her angr 他没说使她生气的话。 He said nthing, hih ade her angr 他一言不发，这使她很生气。 2、 定语从句与强调结构 It is the plae here the lived befre It is in the plae that the lived befre 第一个句子为定语从句，here指代the plae，在定语从句中作状语，第二个句子为强调结构，强调in the plae, that没有意义，把放回后面
24、句子，句子意思完整。 here is it that he fund the lst ath? (强调句型，强调疑问副词here) here is the ath he fund esterda? (定语从句，that指代the ath) 3、 定语从句中的先行词 Is this b the ne that u bught esterda? Is this the b that u bught esterda? 第一个句子中，this b是主句的主语，the ne是先行词。在第二个句子中this是主句的主语，the b是先行词。一定要避免出现：Is this b that u bught es
25、terda? 4、 定语从句与同位语从句 定语从句相当于形容词，它对先行词起修饰、描述或限制作用，而同位语从句则相当于名词，对其前面的词给予说明或作进一步解释，即说明该词所表示的具体内容。例如： The nes that e heard is nt true (定语从句) The nes that he n the prize is nt true （同位语从句） 另: 在“have n idea 从句”结构中，其从句都作idea的同位语。例如： I have n idea hen she ill be ba Tas 2: Filling in and reriting N it is tie
