名詞性從句復習

注意：

1.在名詞性從句中，連接詞的選擇要根據從句的句意和上下文來確定。

2.當從句是陳述句時，通常使用連接詞that（可省略，但在正式文體中建議保

留）；當從句是疑問句時，通常使用whether/if（表示選擇或疑問）或連接代詞

/副詞（表示具體的疑問內容）。

3.在賓語從句中，當從句是特殊疑問句時，其語序要調整為陳述句語序。

4.同位語從句與定語從句的區(qū)別在于：同位語從句是對前面名詞或代詞的具體內

容的闡述或解釋，而定語從句則是對前面名詞或代詞的修飾和限定。

一、主語從句

定義：在句子中充當主語成分的從句。

弓I導詞：that,whether,if,who,whom,which,what,whose,how,when,where等。

使用原則：主語從句通常位于句首，用于描述句子的主要動作或狀態(tài)的執(zhí)行者或

承受者。它可以是陳述句、疑問句或祈使句（但祈使句作為主語從句的情況較少

見）。

構成：主語從句通常由連接詞that（可省略，但當從句中有疑問詞或表示否定、

強調等意義的詞時，通常不省略）或whether/if（表示選擇或疑問）引導，后面

跟完整的句子結構。

狀態(tài)的對象、內容或結果。

連接代詞（who,whom,whose,what,which）或連接副詞（when,where,why,

三、表語從句

定義：在句子中充當表語成分的從句。

弓I導詞：that,whether,if,who,whom,which,what,how,when,where,because,as

if,asthough等。

使用原則：表語從句用于描述主語的特征、性質或狀態(tài)，通常位于系動詞（如be,

become,seem,appear等）之后。

構成：表語從句可以由連接詞that（通常不省略，以保持句子的正式性）或

whether/if（表示疑問或選擇，但較少用于表語從句中）引導，也可以由連接代

詞或連接副詞引導，后面跟完整的句子結構。

例句：

1.Theproblemisthatwedon，thaveenoughmoney.

2.Whathesaidistrue.

強調兩種可能性）

四、同位語從句

定義：對前面的抽象名詞進行具體說明的從句，通常由that引導，有時也可由

whether,if,when,where,why等引導（較少見）。

使用原則：同位語從句用于對前面的名詞或代詞進行進一步的解釋或說明，通常

與前面的名詞或代詞在邏輯上是同位關系。

構成：同位語從句通常由連接詞that（不省略）引導，有時也可以由連接代詞或

連接副詞引導（但較少見），后面跟完整的句子結構。注意，同位語從句的內容
