名詞性從句中what,which與that的區别
例句：What he said sounds reasonable. 他說的聽起來有道理。
What he said是一個由what引導的名詞性從句，作句子的主語, what是複合關系代詞，相當于the thing(s) that。因此，在名詞性從句中可以用the thing(s) that取代的，隻能用what。
①名詞性從句中what與that的區别：that在名詞性從句中不作句子成分，what必須作句子成分。
②名詞性從句中what與which的區别：指代前文已經提到過的對象或範圍時，用which，否則用what。
練習：
①This is _____ he wanted.
A. which B. that C. what D. this
②This is the thing _____ he wanted.
A. this B. that C. what D. who
③She is no longer _____ she used to be.

④She is no longer the person _____ she used to be.
