學習定語從句的常見學習誤區
定語從句也是一種非常常見的從句形式，是各類考試都必定考察的重點，然而定語從句類型繁多，引導詞複雜，讓很多同學都焦頭爛額，小編這次就爲大家帶來學習定語從句的常見誤區，一起學起來吧！
一、誤認爲關係代詞whose只用於修飾人
whose用作疑問代詞時，主要用於指人；但用作關係代詞時，它既可指人也可指物。如：
It was an island, whose name I have forgotten. 它是一座島，名字我忘了。
The factory, whose workers are all women, is closed during the holidays. 這家工廠工人都是婦女，在假期中工廠關門了。
二、混淆定語從句與並列句
請看下面兩題：
1. He has two children, and both of _________ are abroad.
A. them B. which C. whom D. who
2. He has two children, both of _________ are abroad.
A. them B. which C. whom D. who
第1題選A，第2題選C。由於第1題中用了並列連詞and，從而使整個句子爲並列句，and後應是一個獨立的簡單句，所以選A不選C；第2題沒有並列連詞and，both of whom are abroad爲非限制性定語從句。另外，請比較下面一題：
He has two children, both of _________ being abroad.
A. them B. which C. whom D. who
此題答案爲A，其中的both of them being abroad爲獨立主格結構，用作狀語。
請再看一組類似的例子：
1. He wrote a lot of novels, many of _________ translated into foreign languages.
A. it B. them C. which D. that
2. He wrote a lot of novels, many of _________ were translated into foreign languages.
A. it B. them C. which D. that
第1應選B，而不能選C，是因爲句中的 translated 是過去分詞(非謂語動詞)，若選C，則該從句無謂語；第2應選C，因爲句中有謂語 were translated。比較下面一例：
He wrote a lot of novels, and many of _________ were translated into foreign languages.
A. it B. them C. which D. that
此題與上面的第2題不同，兩句間多了一個並列連詞and，說明這是一個並列句，故應選B，則不能選C。
三、混淆關係代詞與關係副詞
有的同學一看到先行詞是表示時間、地點、原因的名詞，就認爲一定要用關係副詞，其實也不一定。在此情況下，還要看關係詞在定語從句中是用作什麼成分，若是用作狀語，則用關係副詞，若不是用作狀語(如用作主語、賓語等)則不能用關係副詞，而用關係代詞。比較：
This is the factory where I want to work. 這就是我想工作的工廠。(work爲不及物動詞where在從句中用作狀語)
This is the factory that I want to visit. 這就是我想參觀的工廠。(visit爲及物動詞，that用作visit的賓語)
The reason why he can’t come is that he is ill. 他沒來的是因爲他病了。(come爲不及物動詞，why在定語從句中用作狀語)
The reason that he put forth is very important. 他提出的理由很重要。(put forth爲及物動詞，that在定語從句中用作其賓語)
比較下面的考題：
1. This is the room _________I lived ten years ago.
A. that B. where C. who D. what
2. This is the room _________I lived in ten years ago.
A. that B. where C. who D. what
3. This is the room _________I bought ten years ago.
A. that B. where C. who D. what
4. This is the room _________I visited ten years ago.
A. that B. where C. who D. what
5. This is the room _________I was born ten years ago.
A. that B. where C. who D. what
第1題選B，因爲 live 是不及物動詞，它無需接賓語；第2題選A，因爲雖然 live 不及物，但live in 卻是及物，它應有自己的賓語；第3、4題也應選A，因爲 buy 和 visit均爲及物動詞，它們應有自己的賓語；第5應選B，因爲 be born 無需有自己的賓語。
四、誤認爲逗號後一定是非限制性定語從句
有的同學一看見逗號，就以爲一定要選which而不選that，但問題是有時根本就不是定語從句。如：
1. If a book is in English, _________ means slow progress for you.
A. as B. which C. what D. that
2. When I say two hours, _________ includes time for eating.
A. as B. which C. what D. that
以上兩題均應選that，而不能選which，因爲它們根本不是定語從句。之所以選that，是因爲句中已有if和when引導的狀語從句，逗號後爲主句，that爲主句主語。
以上就是這次爲大家帶來的內容了，大家都掌握了嗎? 這些都是非常常見的一錯點，大家一定要銘記在心，但不僅僅是記住題目，而是牢牢掌握知識點，學會舉一反三，希望這次的內容能爲備考的大家帶來幫助。
