定语从句 where which that区别的题目

选C the one 指代 the small town
where 可以理解为 in some place 在此句中就是 in the small town
整句理解为I used to work in the small town for years.
Although he is an elderly man , he is strong enough to control his raft in the river where he lives and works with his cormorants .
此句中where是一样的用法
希望帮到你
再问： 提高50分 问： the factory whcih we will visit next week is not far from here 。 为什么这里用which？
再答： 此处visit 后缺宾语，which作visit的宾语 即指代前面那个 the factory 从句即为： we will visit the factory next week 主句 The factory is not far from here. 所以总结下，做此类题目时要看从句缺不缺少成分，缺的是那部分成分，补全后再作答比较好，还有不理解的吗？
