高考英语语法专题复习：定语从句定语从句指在句子中起形容词作用的主谓结构，它通常跟在所修饰的名词或者代词之后。
这些被修饰的名词或代词被称为“先行词”。
引导定语从句的词叫“关系词”。
关系词可分为关系代词和关系副词。
常见的关系代词包括：that（指人或物），which（指代物），who和whom（指代人），whose（指代人或物）。
关系代词引导的从句不是完整的句子，缺少名词成分。
常见关系副词包括：when，where和why。
关系副词引导的从句是完整的句子，不缺少名词成分。
以上两点也是做题时判断关系词的重要依据。
限制性定语从句：紧跟先行词，主句与从句不用逗号分开。
这类从句构成了先行词不可缺少的部分，与主句的关系非常紧密，去掉主句意思往往变得不明确。
例：Any man that / who has a sense of duty won’t do such a thing.任何有责任感的人都不会做这样的事。
非限制性定语从句：从句主句与从句之间有逗号分开，起补充说明作用，如省去，意思仍完整。
这类从句是先行词的附加说明，它与主句往往用逗号隔开，而且与主句的关系也比较松散，就算缺少也不会影响全句的理解。
例：The house, which we bought last month, is very nice.这幢房子很漂亮, 是我们上个月买的。
【注意】非限制性定语从句只能用关系代词which或who、whom、whose等引导，不能用that引导，如：Nobody knows his phone number, which makes it difficult to get in touch with him.（which不能改成that）Our guide, who was a French Canadian, was an excellent cook.（who不能改成that）三、必备知识点1.含有介词的定语从句(1)当定语从句中含有介词，介词放在句末时，who，whom, that，which可省略，但介词在关系代词前时，只能用“介词+which/whom”结构。
