Question

it is April 29 ,2011(when)Prince William and Kate Middleton walked into the palace hall of wedding
答案上说这句话是定语从句,而我们老师上课说it was seven o'clock when we reached the station是时间状语从句,the bus left at 7 o'clock,when we reached the station 是定语从句.
我们老师说错了吗?该怎么区分?

Answer 1

这个是有一点混,教你一个方法：时间状语从句可以反过来说,例如：when we reached the stationit it was seven o'clock .而定语从句则一般不行,反过来它的意思会变化；状语从句的引导词可以换成that.
