10、引导词。例如：I dontlike the way（that /in which）he looks at me. 我不喜欢他那种样子看着我。五、在定语从句中作状语的关系副词when, where, why的用法1、先行词表示时间时，定语从句中的谓语动词如果是不及物动词，用关系副词when 或介词+ which; 如果是及物动词，用which 或 that 都行。例如：I still remember the days when（=on which） we lived together.我仍然记得我们在一起的时光。2、先行词表示地点时，如果定语从句中谓语动词是不及物动词，用关系副词 where

16、the +复数名词这一结构后面的定语从句中的谓语动词，通常用复数形式，与定语从句所靠近的那个复数名词在数上保持一致。但如果 one of the+复数名词这一结构前面带有 the/only/the only 之类的限定语，从句的谓语动词则要用单数形式，此时从句在意义上修饰的3是 the one. 例如：Tom is one of the boys who were late that morning.汤姆是那天早晨迟到的男生之一。Tom is the (only/the only )one of the boys who was late that morning汤.姆是那天早上唯一迟到的男生

17、。九、 that 有时可用作关系副词来代替 when, 引导一个定语从句，修饰表示时间的名词，如 day, time, moment等。例如：I arrived here the day that (=when) he left我.是在他离开的那天到达这儿的。He worked hard the whole time that (=when)he lived here他.在这里的整个时间工作都很努力。十、 than 和 but 也可用作关系代词引导定语从句1、 than 用作关系代词，在定语从句中作主语或宾语。例如：You spent more money than was intended
