有人說這個是主語從句，我沒了解。期望各位大神可以剖析一下句子的結構（哪個作哪個的主語）。

what在這種句子中是縮合連接代詞（Condensed conjunctive pronoun）因為其形式和功用與關系代詞相似，所以歸入關系代詞的范疇。縮合連接代詞主要由先行詞與關系代詞縮合而成，多用以引導名詞性從句。特征是其形式和功用與關系代詞相似。中文名縮合連接代詞外文名Condensed conjunctive pronoun特征其形式和功用與關系代詞相似范疇歸入關系代詞的范疇這種代詞主要有: what who that whatever whoever whichever 帶-ever的詞總是有any的意思，語氣較強。現將上述縮合連接代詞的使用方法舉例說明如下：what What I want is water. 我所要的是水。（what I want 用作主語，后接單數動詞 is） What I want are apples. 我所要的是蘋果。（what I want 用作主語，后接復數動詞 are） I eat what I like. 我吃我所喜歡的東西。（what I like 用作賓語） that is what I have to say. 這就是我所要說的話。（what I have to say 用作表語） I gave him what help I could. 我盡我所能幫助了他。（what help I could 用作直接賓語，what 在此 = any）who Who breaks pays. 損害須賠償。（who breaks 用作主語，who 的這種使用方法現已不多見） Tom may marry who he likes. 湯姆可以與任何他所喜歡的人結婚。（who he likes 用作賓語。注意這種從句只可用like, choose,please. want. wish等動詞） You are not who I thought you were. 你已不是我過去所想像的人。（who引導一表語從句）that Handsome is that handsome does. 做的漂亮才是真漂亮。（that 引導表語從句） It was you that said so. 是你如此說的。（that 引導主語從句，it 是一引語）whichYou can take which you like. 你喜歡拿哪一個就能拿哪一個。（which 引導一賓語從句）whateverI'll do whatever I can do. 我關做我所能做的事。（whatever 引導一賓語從句）whoeverWhoever is TOP form wins the game when two matched players meet. 兩強相爭勇者勝。（whoever 引導一主語從句）whicheverYou can take whichever you like. 你愛拿什么就拿什么吧。（whichever 引導一賓語從句，其語氣較which強）帶有-ever的縮合連接代詞有時有“不論”的意思，可引導讓步狀語從句。如： I'll stand by you whatever happens. 不論發生啥事，我都和你站在一塊。 The final between the teams, whatever the result, is splendid. 兩隊之間的決賽，不論結果怎么樣，一直精彩的。（注意 whatever the result 后省去了 it is） Whoever says so, it's not true. 無論是哪個說的，這話虛假。（whoever=no matter who） Her sister - or her friend - whichever it was - was an uncommonly pretty girl. 她的妹妹，或者是他的朋友，無論是哪一個，真是漂亮出眾（whichever=no matter which）
