Is there anything else___ you require? A. which B. that C. who D. what;修饰主语、宾语、表语的句子就叫做定语从句，作用相当于一个形容词。 引导定语从句的关联词有：;定语从句的位置;;This is the detective who came from London. The book which I am reading is written by Tomas Hardy. The desk whose leg is broken is very old. This is the room that Shakespeare was born in.; that指人或物， 在定语从句中做主语或宾语, 作宾语时可以省略。;Who 指人，在从句中可做主语和宾语。作宾语时可省略。;whom指人, 在从句中作宾语, 可省略。; which 指物, 在句中作主语或宾语, 作宾语时可以省略。;I have read the newspaper.; * whose 指人或物，在从句中作定语。;; (1) 如果先行词是all, much, anything, something, nothing, everything, little, none等不定代词，关系代词一般只用that，不用which。例如： All the people that are present burst into tears. (2) 先行词有两个，既有人也有物，要用that。 We were talking about the persons and things that we remembered in our school.;(3) 如果先行词被形容词最高级以及first, last, any, only, few, mush, no, some, very等词修饰，关系代词常用that, 不用which, who，或whom。例如： That is the only way that leads to your success .那是通向你成功的唯一之路。 We have to consider the first thing that starts our work .我们必须要考虑启动我们工作的第一件事。 ;2. 宜用which引导的定语从句 当定语从句的介词提前时，要用which。 The house in which they lived last year has been rebuilt. 引导非限制性定语从句时，要用which。 He bought a railway ticket for the woman, which helped her a lot.;as, which 非限定性定语从句 由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that。As一般放在句首,which在句中。 As we know, smoking is harmful to ones health. The sun heats the earth, which is very important to us.　　 ;as 和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点：　 (1) as 引导非限制性定语从句，可放在主句之前，或者主句之后，甚至可以切割一个主句；which引导的非限制性定语从句只能放在主句之后。另外，as有“正如……，正像……”的意思 (2）as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用which。;(3)当先行词受such, the same修饰时，常用asI have never heard such a story as he tells.He
