主語從句

(1)從屬連詞：that、whether、if等。
(2)連接代詞：wh、whse、whm、which、what、whever、whmever、whichever、whatever等。
(3)連接副詞：when、where、why、hw等。

四、連接副詞引導(dǎo)的主語從句
連接副詞when、where、hw、why引導(dǎo)主語從句時(shí)，在句中既是連接詞，又作狀語；where作地點(diǎn)狀語；when作時(shí)間狀語；why作原因狀語。連接副詞引導(dǎo)的主語從句，也常用it作形式主語。

表語從句
一、表語從句的含義和構(gòu)成
1．含義：表語從句是指一個句子作為表語，放在系動詞之后，這種從句往往是對主句的主語進(jìn)行進(jìn)一步解釋說明。
2．構(gòu)成：其一般結(jié)構(gòu)為“主語＋系動詞＋連接詞連接的表語從句”。
3．可接表語從句的系動詞有：be, lk, seem, sund, appear等。引導(dǎo)表語從句的連接詞有連接代詞(what、wh、whm、which、whse等)，連接副詞(when、where、hw、why等)以及that、whether、as if/as thugh、because 等。
二、表語從句的用法
1．that引導(dǎo)表語從句

1．有的集體名詞表示復(fù)數(shù)含義，作主語時(shí)謂語通常也用復(fù)數(shù)形式，比如 cattle、 peple、 plice 等。

(1)強(qiáng)調(diào)整體，謂語動詞用單數(shù)：

晚會上觀眾很多。
His family has mved int the new huse.
他家已搬進(jìn)新房子。

3．有的集體名詞作主語時(shí)，謂語動詞只能用單數(shù)形式，比如baggage、clthing、equipment、furniture、jewellery、luggage、scenery、petry等。
The furniture in the rm has been made t rder.
這個房間的家具是定做的。
