1 the neighborhood where (== in the neighbourhood) I grew up was the sort of place in which (==where) people dream of raising children
两个定语从句部分,where和in which都做各自句子的地点状语.where和in which可以互换.
2 some of the people WHO went to school with ME still live there.
(你漏了两个单词.)who == the people .这也是定语从句.who是定语从句的连接词,也是从句部分的主语.
