英文關係副詞-how(Relative adverbs-how in English)

關係副詞how用來表示「方法」。

how=in +which
但關係副詞how只能修飾先行詞the way，而且the way和how不能連用，所以只能省略先行詞the way。
Jack wants to know the way in which a pizza is made.(Jack想知道做披薩的方法)
=Jack wants to know the way a pizza is made. 省略in which的用法比較普遍
=Jack wants to know how a pizza is made.
Jack wants to know the way  how a pizza is made.(X，要把the way去掉)
