名詞性wh-從句
1)由wh-詞引導的名詞從句叫做名詞性wh-從句。Wh-詞包括who, whom,. whose, whoever, what, whatever, which, whichever等連接代詞和where, when, how, why等連接副詞。Wh-從句的語法功能除了和that-從句一樣外,還可充儅介詞賓語、賓語補語和間接賓語等,例如:
主語: How the book will sell depends on its author. 書銷售如何取決於作者本人。
直接賓語:In one's own home one can do what one likes. 在自己家裡可以隨心所欲。
間接賓語:The club will give whoever wins a prize. 俱樂部將給得勝者設獎。
表語: My question is who will take over president of the Foundation. 我的問題是誰將接任該基金會主蓆職位。
賓語補足語:She will name him whatever she wants to. 她高興給他起什麼名字就取什麼名字。
同位語: I have no idea when he will return. 我不知道他什麼時候廻來。
形容詞賓語:I'm not sure why she refused their invitation. 我尚不能肯定她爲什麼拒絕他們的邀請。
介詞賓語: That depends on where we shall go. 那取決於我們去哪兒。
2)Wh-從句作主語也常用先行詞it做形式主語,而將wh-從句置於句末,例如:
It is not yet decided who will do that job. 還沒決定誰做這項工作。
It remains unknown when they are going to get married. 他們何時結婚依然不明。
