一、混淆定語從句與并列句

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

【分析】第(1)題選A，第(2)題選C。由于第(1)題中用了并列連詞and，從而使整個句子為并列句，and后應是一個獨立的簡單句，所以選A不選C；第(2)題沒有并列連詞and，both of whom are abroad為非限制性定語從句。

二、混淆定語從句與表語(從句)

請看下面的試題：

(1) Your coat is still _____ you left it.

A. where B. there C. there where D. the place where

【分析】答案選A，where引導的是表語從句(=在…的地方)，而不是定語從句。

(2) Is this school _____ your father worked in ten years ago?

A. where B. what C. that D. the one

【分析】答案選D，this school為句子主語，the one 為表語，your father worked in…為定語從句。不要誤認為this是句子主語，否則school前應加冠詞the。比較：

Is this the school _____ your father worked in ten years ago?

A. where B. what C. that D. the one (選C)

Is this the school _____ your father worked ten years ago?

A. where B. what C. that D. the one (選A)

三、混淆定語從句與狀語從句

請看下面的試題：

(1) I went upstairs ______I heard some crying.

A. where B. when C. that D. which

【分析】答案是B而不是A，when的意思是“當…的時候”，引導的是時間狀語從句。(upstairs為副詞，不宜用作先行詞)

(2) He is _____ a clever boy _____ we all like.

A. such, that B. such, as C. so, that D. so, as

【分析】答案應選B，而不是A。such … that …(如此…以致…)用于引導結果狀語從句，其中的that不充當句子成分，而such…as…中的as為關系代詞，用以引導定語從句并在定語從句充當句子成分。上句中第二空之所以選as，是因為它用作動詞like賓語。

四、誤加與關系代詞同義的人稱代詞

誤：He is a man everyone respects him.

正：He is a man everyone respects. 他是一個人人都敬重的人。
