限制性定語從句對被修飾的先行詞有限定製約作用，使該詞的含義更具體，更明確。下面是小編爲大家推薦限定性定語從句的內容，希望能夠幫助到你，歡迎大家的閱讀參考。
關係代詞
⒈ that既可代表事物也可代表人，which代表事物；它們在從句中作主語或賓語，that在從句中作賓語時常可省略代詞，which在從句中作賓語可以省略。[eg：this is the book which you want。]而且，如果which在從句中作“不及物動詞+介詞”的介詞的賓語，注意介詞不要丟掉，而且介詞總是放在關係代詞which的前邊，但有的則放在它原來的位置
⒉ which作賓語時，根據先行詞與定語從句之間的語義關係，先行詞與which之間的介詞不能丟（eg.I lost my key in the theatre where I saw this film=====I lost my key in the theatre in which I saw this film.)
⒊ 代表物時多用which，但在帶有下列詞的句子中用that而不用which，這些詞包括當先行詞是anything,everything,nothing,none等不定代詞時，或者是由every,any,all,some,no,little,few,much等修飾時等，這時的that常被省略 還有先行詞前有序數詞或形容詞最高級修飾時，或先行詞就是序數詞或最高級時.以及先行詞中既有人又有物時.還有句中前面有which時，都只能用that
⒋ who和whom引導的從句用來修飾人，分別作從句中的主語和賓語，whom作賓語時，要注意它可以作動詞的賓語也可以作介詞的賓語
關係副詞
關係副詞=介詞+關係代詞
why=for which
where=in/ at/ on/ ... which （介詞同先行詞搭配)
when=during/ on/ in/ ... which （介詞同先行詞搭配）
whose=of which/ whom
⒈ where是關係副詞，用來表示地點的定語從句
⒉ when引導定語從句表示時間[注]值得一提的是，表示時間“time"一詞的定語從句只用when引導，有時不用任何關係代詞，當然也不用that引導
By the time you arrive in London,we will have stayed there for two weeks. I still remember the first time I met her. Each time he goes to business trip,he brings a lot of living necessities,such as towels,soap,toothbrush etc.
⒊ whose是關係代詞，修飾名詞作定語，相當於所修飾成分的前置所有格.它引導的從句可以修飾人和物，當它引導的從句修飾物體時，可以與 of which 調換，表達的意思一樣.
⒋ 當從句的邏輯主語是some,any,no,somebody,anybody,nobody,something,anything,everything或nothing時，常用there is來引導
There is somebody here who wants to speak to you. 這裏有人要和你說話。

【解析】
1. D。“position”爲先行詞，後面是其定語從句，關係詞在從句中作的是地點狀語，因此，應該使用關係副詞“where”來引導定語從句。因此，正確答案爲D選項。
2. D。process意爲“過程”；分析從句結構，從句爲完整的被動結構，in which(the process)作從句的狀語。
3. B。when引導定義從句，在從句中做時間狀語，修飾先行詞an age（時代）. 此處的when=at which。
4. C。句意：該獎項將會頒發給其作品最具有想象力的.作者。 先行詞爲the writer, 代入定語從句後爲：The writer’s story shows the most imagination.，由此可見，先行詞在定語從句中作story的定語，故答案爲C項。
5. A。句意：她具有給學生營造一種允許他們自由交流的氛圍的天賦。分析句子結構可知，定語從句“_____ allows them to communicate freely with each other”修飾先行詞atmosphere，將先行詞代入從句後爲：The atmosphere allows them to communicate freely with each other，由此可知先行詞在定語從句中作主語，而且指代物，所以需用關係代詞which，故正確答案爲A項。
6. A。句意：英語是一種被幾種不同文化共有的語言，每種文化使用英語多少有些不同。本題考查非限制性定語從句。先行詞爲cultures，將先行詞代入定語從句後爲：Each of the cultures uses it somewhat differently，由此可見先行詞在定語從句中作介詞of的賓語，且of被提前，故答案爲A項。what不能引導定語從句，故被排除；如選C項，需在each of前加並列連詞。
7. B。句意：那些不是很活躍，或者飲食中熱量太高的孩子會很快長胖。先行詞爲children。 or連接兩個並列的定語從句，第一個定語從句的關係詞爲who，第二個關係詞爲考查點，先行詞children在第二個定語從句中與從句中的主語diet形成所屬關係：children’s diet，故選擇B項。
