2.当先行词为all，any，much，many词时，只能使用“that”。tom told her mother all had happened.3.当先行词是形容词最高级或被形容词最高级修饰时，只能使用“that”。 this is the most wonderful time i have ever had. 4.当先行词是序数词修饰时，只能使用“that”。 he was the first person passed the exam. 5.先行词被the only，the very，the same，the last修饰时，只能使用“that”。例：1.this will be the last chance he can get. 2.he is the only person can help you out.人。6.先行词里同时含有人或物时，只能使用“that”。 they talked of things and persons they remembered in the school. 7.当主句是以who，which 开头的特殊疑问句或先行词是who时，只能使用“that”。 which is the book he bought from the library yesterday?
