名詞性從句考點及命題規(guī)律分析

1. 根據語境考查不同連接詞的辨析

Why not try your lick downtown, Bob? That’s _______ the best jobs are. (浙江卷)

A. where               B. what                  C. when                D. why

答案為A。where在此引導表語從句，表示“……的地方”，又如：This is where the river is deepest. 這是河流的最深處。This is where I first met her. 這就是我初次與她會面的地方。

3. 考查what的用法

_______ matters most in learning English is enough practice. (全國II)

A. What                B. Why                  C. Where               D. Which

答案為A。what在此引導主語從句，相當于the thing that。

_______ parents say and do has a life-long effect on their children. (陜西卷)

A. That                  B. Which               C. What                 D. As

答案為C。what在此引導主語從句，相當于the thing that。

2. 根據句法功能考查連接詞的選用

Choosing the right dictionary depends on _______ you want to use it for. (江蘇卷)

A. what                 B. why                   C. how                   D. whether

答案為A。what用以引導賓語從句，用作介詞on的賓語，其中的what在從句中用作介詞for的賓語。四個選項中有A為連接代詞，可以用作賓語，其中的why和how為連接副詞，只能用作狀語；而whether不充當句子成分。

4. 考查whatever等的用法

Could I speak to _______ is in charge of International Sales, please? (山東卷)

A. anyone            B. someone          C. whoever           D. no matter who

答案為C。whoever有兩個主要用法：一是用于引導名詞性從句，其意相當于the man who；二是用于引導狀語從句，其意相當于no matter who。句中的whoever引導賓語從句，用作介詞to的賓語，故選C不選D。

5. 在復雜結構中考查名詞性從句的使用

Having checked the doors were closed, and _______ all the lights were off, the boy opened the door to his bedroom. (湖南卷)

A. why                  B. that                    C. when                D. ours

答案為B。that在此用于引導賓語從句，用作動詞check的賓語。這是一個比較復雜的句子，句中的現在分詞having checked帶有兩個賓語從句 (that) the doors were closed和that all the lights were off，只是前面一個賓語從句省略了引導詞that。

6. 考查同位語從句的運用

A warm thought suddenly came to me _______ I might use the pocket money to buy some flowers for my mother’s birthday. (安徽卷)

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

答案為C。that在此引導同位語從句，修飾名詞thought。此題的難點是，名詞thought與修飾它的同位語從句被分離開了。
