是含有定語從句的復合句.which she bought is beautiful是定語從句修飾
the flowers.which 在從句中作"bought"的賓語
同位語從句是對前面的名詞作補充說明,不起修飾作用
that 引導同位語從句時,that 不充當成分
但是that 引導定語從句時,that 在從句中充當主語或賓語.
比如:這個句子The flowers which she bought is beautiful.可把which換成that
但:The news that our team win the game is exciting.這個句子中 that our team win the game 是同位語從句,說明news 的具體內容,that 從句中不充當成分.
which 引導同位語從句的話,which 是哪一個的意思.
例:I don't care the problem which team will win the game.
which team will win the game是同位語從句.說明 problem 的具體內容.
主語從句:是指作主語的句子.
例:That our team has won the game is exciting.
or:It's exciting that our team has won the game.(it是形式主語)
That our team has won the game 是主語從句.謂語是is
不再糾結了.
