Trees grow well( )there is enough water.A.that B.in which C.

C wherewhere 带出的是地点状语从句。where前面“trees grow well”其实在结构上已经是一个完整的句子,但是意思不完整。“there is enough water”也是结构完整的句子,然而怎样衔接呢?那就是“在那些（where）有足够水分的地方”,树木生长得很好。像那个谚语也是 Where there's a will,there's a way。（有志者事竟成）there's a will和there's a way都是结构完整的句子,where带出的是地方,因此前面那部分实质上是一个从句。句子的直译是“哪里有意志,哪里便有出路”。in which 前面要加名词I often visit the museum in which there are a lot of cultural relics。此处in which 等于 where。一楼答案是错的。也请楼上不要抄我的答案!
