名詞性從句解析主語從句，賓語從句，表語從句，同位語從句什么是從句？舉個栗子：ThegirlwhooftenhelpswithmyEnglishisfromEngland.所謂從句就是使用一個句子充當某個句子成分從句有主語從句，賓語從句，表語從句，同位語從句，定語從句，狀語從句等換句話說，連接詞后面的句子就是從句各個從句連接詞包括：that，whether，if，what，who，which，whatever，whoever，whichever，whom，whose，how，when，where，why簡單句句中哪些成分會用名詞？簡單句結構：1.主語+系動詞+表語(n.＋link.v.＋n)2.主語+謂語（及物動詞）+賓語(n.＋v.＋n.)例：Amyisagirl

Amylikesflowers可知：句中主語，賓語，表語可以是名詞什么是名詞性從句？首先，從句的概念是：連接詞＋句子＝從句例：Whoeverbreaksthelawwillbepunished.所以，名詞性從句

連詞＋句子＝名詞名詞性的從句種類有：主語從句，賓語從句，表語從句，同位語從句

所以，主語從句是

n.(主語)＋v.（謂語）＋n.（賓語）

（連詞＋句子）＋v.＋n.賓語從句是n.＋v.＋n.

n.＋v.＋（連詞＋句子）表語從句為n.＋link.v.＋nn＋link.v.＋(連接詞＋句子)同位語從句為n.＋v.＋n.+（連接詞＋句子）或

n.＋（連接詞＋句子）＋v.＋n.注：同位語從句的作用是放在名詞后起補充說明的作用
