回答: 英语各类从句可以归纳为三大类。第一类是形容词（定语）从句。它们一般由关系代词“who, which，that”，关系副词“where，when，which，that”，关系形容词“whose”来引导。第二类是状语从句。其表示因果关系的连词有“because，since，so that，whereas”等；表示时间的连词有“after，before，by the time，when，while，until，once，as，as soon as，since，now that”等；表示条件的有“if，even if，unless，only if，once，in case (that)，provide that，in the event (that)，whether or not”等；表示让步的有“although，though，while，whereas，even though”等；表示方式的有“as though，as if”等；表示比较的有“than，as”等。第三类是名词性从句，一般由“that”引导，做句子的主语、动词宾语、介词宾语、同位语等。关系代词和关系形容词也可引导名词性从句。疑问副词“when，where，why，how”也可引导名词性从句作主语和宾语。
