名师详解语法易错题（10）

12. He believes in himself, _________, in my opinion, is of the most important.

A. that                     B. which                   C. what                    D. as

【分析】此题应选B，句中的 in my opinion 为插入成分，如果将其撇开，句子则为 He believes in himself, _________ is of the most important. 空格处显然应填 which，用以引导一个非限制性的定语从句，句意为“他很自信，我认为这是最重要的”。

13. She promised _________ he had enough money she would marry him.

A. that                     B. if                         C. that if                  D. if that

【分析】此题应选 C，其余几项均有可能误选。句子的正常词序为 She promised that she would marry him if he had enough money. 由于将条件状语从句 if he had enough money 插入动词 promised 与其宾语从句之间，从而导致许多同学误选。顺便说一句，本来动词 promise 后接宾语从句时，引导宾语从句的 that 是可以省略的，但是按英语习惯，当动词与其宾语从句之间插有其他成分时，引导宾语从句的 that 通常不宜省略，所以此题不宜选B。又如：

She promised that if anyone found her son she would give him a lot of money. 她答应要是谁找到她儿子，她会给他一大笔钱。（句子可改为 She promised that she would give him a lot of money if anyone found her son.）

He said that when his wife came back he would leave. 他说等他妻子一回来，他就离开。(句子可改写为 He said that he would leave when his wife came back.)

Tell him that if he is at home I’ll come to see him. 告诉他，如果他在家，我就去看他。(句子可改写为 Tell him (that) I’ll come to see him if he is at home.)

14. The train, _________ takes only two hours to get there, is quicker than the bus, _________ takes three.

A. which, it              B. it, which              C. which, which        D. it, it

【分析】此题答案选C，主句为 The train is quicker than the bus. 其中的 which takes only two hours to get there 和 which takes three 是插入句中修饰 the train 和 the bus 的两个非限制性定语从句。类例：

The man, _________ is a lawyer, earns more than his wife, _________ works as a nurse.

A. who, she              B. he, who                C. who, who             D. he, she

答案选C，主句为 The man earns more than his wife. 其中的 who is a lawyer 和 who works as a nurse 是两个非限制性定语从句，分别修饰 the man 和 his wife。

15. By the window sits his wife, who, dressed in black, _________ like my aunt.

A. look                    B. looking                C. looked                 D. looks

答案选D，但B和C可能被误选。此句的基本结构是 His wife sits by the window，由于句子主语 his wife 带有自己较复杂的修饰语，所以采用了倒装语序(By the window sits his wife…)。另一方面，由于 his wife 后接的定语从句 who looks like my aunt中插入了一个过去分词短语(dressed in black)，所以有的同学没有意识到 looks 是定语从句的谓语，而考虑到选 looked 与前面的过去分词 dressed 保持一致。
