Question

请教初中英语问题，求达人解答！

Answer 1

C. "his students can practice their speaking skills"这句话完整，不缺成分，排除which，因为which是代词，一定要有成分，这是atmosphere引导的地点定语从句，用where. 对于A,D两个选项，是介词搭配不对。若是in which就对，因为可以说成“his students can practice their speaking skill in atmosphere."

Answer 2

c
where 相当于说in that atmosphere

追问

我定语从句不太理解，能再详细点吗？

Answer 3

in which = where 故选C
