【异混易错】as和which引导定语从句的区别
as引导非限制性定语从句，既可在主句前，又可在主句后,有时还可插入主句中，as常译为“正如……,正像……”.从句的谓语动词多为see,know,Expect,say,mention,report等.
The air quality in the city，as is shown in the report，has improved over the past two months.正如报告所显示的，在过去的两个月里，这个城市的空气质量已有所改善。
which引导非限制性定语从句修饰前面整个句子时，只能置于主句后，常译为“这一点，这件事”等，这时它所引导的从句与主句之间常含有并列或因果关系。
Mo Yan was awarded the Nobel Prize for Literature in 2017，which made one of the Chinese people’s long－held dreams come true.莫言被授予2017年诺贝尔文学奖，这使中国人长久以来拥有的梦想之一变成现实。

【异混易错】
(1)whom，which，that在从句中作宾语时可省略；但介词提前that。(2)as用在限制性定语从句中时先行词必须有such或the same等修饰且as在从句中作宾语时不能省略。(3)定语从句中的主谓一致：关系代词在定语从句中作主语时从句谓语动词的单复数与先行词保持一致。(the) one of＋复数名词”后接定语从句时当先行词为“one of＋复数名词”时从句的谓语动词用复数；当先行词为“the(only/very/right) one of＋复数名词”时从句的谓语动词用单数。

1．首先判断是不是定语从句。如果是定语从句就要找准先行词；选用关系代词还是关系副词取决于从句中的谓语动词.及物动词后面无宾语，就必须用关系代词；而不及物动词则 要求用关系副词。
2．准确判断先行词在从句中的成分(主、宾、定、表、状),才能正确选择出关系代词/关系副词。如果先行词在从句中作 主语、宾语、定语，选择关系代词(which，that，who， whom，whose)；如果先行词在从句中作状语，选择关系副词(when，where，why)。熟练掌握每个关系词的用法是解题 的关键。

【热点突破】 “介词＋关系代词”引导的定语从句
1．依据定语从句中动词所需要的某种习惯搭配来确定。

Care of the soul is a gradual process in which even the small details of life should be considered.
心灵的关爱是一个渐进的过程，在这个过程中即使是细微的 生活细节都应该被考虑在内。(in...process)
3．依据所表达的意思来确定。
The colorless gas without which we cannot live is called oxygen.这种无色气体就是氧气，离了它我们不能活。
