初中英语定语从句中关系代词that与which的使用区别是什么

that和which做比较,主要在于它们在定语从句中的用法 that 和which在定语从句中都是做关系代词,指代先行词是事物的名词或代词（that还可以指代人,which 不可以）。通常情况下二者可以互换。区别：关系代词用that（不用which）的情况：1。先行词是all,anything,everything,nothing等,关系代词应用that That's all that he told me。2。先行词前有the only,the same,the very 或no,little,much,any,every,all 等修饰时,关系代词应用that She is the only person that I know in this company。3。先行词前有序数词或形容词最高级修饰时,关系代词常用that The first thing that I want to do is to take it away。4。当先行词同时含有"人"或"物"时,关系代词应用that 5。在固定结构the same。。。that。。。; so。。。that。。。; such。。。that。。。以及it is/was。。。that。。。的强调句型中,要用that This is the same park that we once visited。6。如主句以there be开头时,关系代词应用that There is a room that has two windows。关系代词用which（不用that）的情况：1。非限制性定语从句中关系代词一般要用which She won the competition,which made the whole family very happy。2。关系代词前如有介词,关系代词须用 which; 如把介词移至句末,可用that(或省略) There’s only one problem about which they disagree。This is the key (that) she was looking for。3。如果先行词是that,关系代词应用 which I know that which you told me。4。如先行词和定语从句之间被其它较长的成分分隔,常用which Larry told her the story of the young airman which I narrated at the beginning of this book。(先行词为story) 5。在"those+复数形式的名词"结构中,其后的关系代词多用which A shop should keep a stock of those goods which sell best。6。一个句子中如有两个定语从句,第一个定语从句用了关系代词that,第二个从句中的关系代词宜用which;但在平行结构中,应重复同一个关系代词 This is the book that you bought which you have lost。I have a house which is located on the hillside,which faces the south。此外,that还可引导同位语从句,which不能 I have heard the news that they had won the game。
