01定语从句引导定语从句的关系代词有 that,which,who（宾格 whom），所有格 whose）和关系副词 where when why 等，关系代词或关系副词在定语从句中充当一个成分，关系代词that，which,who,whom 等在从句中分别作主语或宾语，whose 在从句中作定语，而关系副词 when,where,why 等在从句中作状语。 ① I will never forget the days when/in which we worked together. ② I will never forget the days which/that we spent together. 解析在句①中，表示时间的名词 the days 在从句中充当的是状语，所以用关系副词 when 来代指，引导定语从句修饰先行词 the days；而在句②中，表示时间的名词 the days 在从句中充当的是动词spent 的宾语，所以用关系代词 that 或 which 来代指。 同样，表示地点或原因的名词如果在从句中作状语，则用关系副词 where 或 why 来代指；如果在从句中作动词的宾语，则用which 或 that 来代替。① This is the factory where/in which I worked.（作状语） ② This is the factory that/which I visited years ago.（作宾语） 注：当先行词为 time,reason, place 时，引导词可以省略。 ① This was the first (when/what) I had serious trouble with my boss. ② That is the reason (why) I did it. ③ This is the place (where) we met yesterday. 另外，定语从句中谓语动词数应与先行词数一致。① Mr. Jackson is the only foreigner that is present at the party.② He is one of the students who were praised by the teacher. 解析在句①中，先行词 foreigner 被 only 修饰，强调只有一个，所以从句中谓语动词用单数形式。而在句②中，who 引导的定语从句修饰先行词 the students，为复数，所以从句谓语动词应为复数。 02名词性从句中的易错点*that 引导的定语从句与同位语从句 定语从句与前面的的名词是修饰与被修饰的关系，“……的名词”，而同位语从句是用来说明前面名词的内容。与 that 从句同位的名词必须是一些表示事实或概念的抽象名词，如：fact,news,belief,truth,reply 等。That在定语从句中必须作成分，可用 which 或 who/whom 代替，而that 在同位语从句中不充当任何句子成分，只起连接作用。 ① Along with the letter w...
