which引導的非限制性定語從句既可以指整個句子內容，也可以指句子的部分內容(如單詞或詞組等)，在句子中可以作主語、賓語(動詞或介詞 的.)、定語等。以下是關於which引導的定語從句，以供參考!
He helped to improve the local police force and to establish a hospital and a college which later became the University of Pennsylvania.
which可以引導定語從句，修飾表示事物的先行詞，在定語從句中充當主語、賓語或者表語。在上文中，關係代詞which在修飾college，在定語從句中充當主語。
which和that引導的定語從句
that which代表物，區別聽我來敘述，
先行若是不定代，that就把which踹;
先行詞前有兩數，就用that定無誤;
先行詞前最高級，還用that必無疑;
句中若有therebe，that應把which替;
先行主中作表語，避免重複從句裏;
Just the only very same last, 其後也要用that。
