能,用关系代词;不能,用关系副词•Eg.l will never forget the day that I spent with my parents.(定从中动词spent 与先行词the day 构成spent the day ,所以用关系代词that或which或省略)方法二:找出先行词和定语从句,看定语从句是否缺少主语、宾语或表语,如缺少,用关系代词。
如不缺少,定语从句所表达意思相对完整,用关系副词。
eg:①.This is the factory _______ made cars .(缺少主语,所以用关系代词that或which,作主语不能省略)②.This is the reason ___________ he was late for school.(定语从句he was late for school 表达意思相对完整,所以用关系副词why或介词+关系代词for which)注意:当先行词为case、position、point、situation、society、activity 等扌由象意义的名词时,常用关系副词where引导定语从句.eg:He got himself into a dan gerous situati on where he may lose con trol of the pla ne . 考点二.定从中that与which的区别1.关系代词只用that的情况。
(1)当先行词为不定代词(all、much、little、few、some、any、none、one、something、anything、everything 等)或先行词被不定形容词(all、many、some、few、little 等)修饰时。

②.Today I bought the same bike as_Tom did last week .(同样的但不是同一辆)比较:Today he wears the same coat that he did yesterday . (同一件衣服)(2)as 常用于固定句型中:as we all / everyboby know(s), ,as is often the case,as we expect等。
eg:As we all kno w,Zhe ngzhou is an attractive city.2.在非限制性定语从句中,as与which的区别⑴指代整句话内容时,as可位于主句前面、中间或后面;而which 一般位于主句后。
