②在先行词与定语从句之间插入一个定语。
如：Do you remember one afternoon ten years ago when I came to your house and borrowed a diamond necklace?你还记得吗，十年前的一天下午，我来到你家，找你借了一条钻石项链?
when I came to your house and borrowed a diamond necklace实际上是修饰afternoon而不是修饰 years。ten years ago 实际上是定语后置修饰afternoon。
③先行词与定语从句被谓语分隔开来。此时，先行词通常是句子的主语，因定语从句较长，主句谓语较短，为使句子平衡，常将定语从句移至谓语之后 如：
A new master will come tomorrow who will teach you German.
明天，新(男)老师将来较你德语。
