定語從句是高中英語學習的重要語法項目之一，也是歷年高考的熱點。它的難度主要是通過改變句子的正常語序或借助于其它語法項目來體現(xiàn)的，為了提高同學們的應變能力， 現(xiàn)對定語從句的一些常見考點歸納和總結如下：
一、疑問句中考查定語從句
1. Is this the farm ________ you visited last week?
A. where B. the one C. on which D. /
【解析】答案是D。命題人經常利用疑問句的特殊結構來干擾學生的正確選擇。遇到這類定語從句時，最好的辦法是先把疑問句還原成陳述句，然后判斷誰是先行詞，再看關系詞在定語從句中所充當?shù)某煞�，最后確定正確答案。
二、倒裝句中考查定語從句
2. We came to a place, ________ stood a big tower.
A. which B. that C. / D. where
【解析】正確答案是D。為了保持句子平衡，句子用了倒裝語序。倒裝的使用使定語從句的結構變得較為特殊，因此對于使用倒裝語序的定語從句，應先把倒裝語序還原成正常語序，這樣句子結構就比較清晰了。
三、 拆分詞組和固定搭配
3. The second is connected with the use ________ the body makes of food.
A. of which B. where C. to do D. that
4. Why can't you realize the part ________ they have played in our life?
A. which B. on which C. when D. where
【解析】正確答案分別是D和A。一些詞組和搭配被拆開后，句子的含義就變得難以理解。首先把拆開的詞組復原是理解此類定語從句的關鍵。上述句子中包含以下詞組：make use of, play a part (in)。
四、添加插入語或狀語
5. The scientist has made another discovery, _______ I believe is of great importance.
A. that B. / C. which D. why
【解析】應選擇C。這類句子主要利用插入語或狀語的添加來增加試題的難度。常見的插入語有：I think (suppose, expect, believe, imagine), in my opinion, to tell you the truth等。做這類題目時，最佳的辦法是先刪去插入語或狀語，這樣句子的主干部分就一目了然了。
五、插入非謂語動詞
6. Is this the man ________ you want to have ________
the radio for me?
A. who; repaired B. that; repaired
C. whom; repairing D. that; repair
【解析】D項正確。非謂語動詞是英語中難度較大的語法項目之一，因而在定語從句中加入非謂語動詞就成了學生最易失分的題目。對付這類題目最有效的辦法就是將句子還原。如：我們可以把幾個句子中的定語從句進行還原，還原后的句子應是：You want to have the man repair the radio for me.
