一本词典对cancer的解释是这样的:a serious disease in which harmful cells spread through the body.
请大侠解释一下这句话的结构,其中的in which能否用where代替?分不多,)
就是定语从句,理论上,完全可以用where 代替.
Cancer is a serious disease【 in which harmful cells spread through the body.】
癌症是一种【有害细胞遍布全身的】严重的疾病.
再问: 首先感谢你的回答。我觉得只能用in which而不能用where代替,如果先行词是地点名词是可以用where的。首先我不明白的是in which在从句中做什么成分?宾语?状语?其次in在从句中和什么做搭配?(比如This is the house which i was born in.=This is the house in which i was born.in和从句中的born搭配)
再答: in which 在句子中作状语;in和什么词搭配,你得看先行词。你给的例句中,先行词是house,be born in the house. 虽然where的先行词通常是表示地点场合的名词,但疾病作先行词也不少见,比如 Rheumatoid arthritis is considered an autoimmune disease where the body attacks healthy cells.又: AIDS is a disease where the body is unable to fight off many infectious diseases as it normally could. 其实关系副词(where, when, why)引导定语从句时,在意义上常常相当于一个“介词+ which”结构。where=in which 或at which; why= for which; when=at/on/during/in which 所以理论上是可以替代的。
