when,where和why引导的定语从句可用“介词+关系代词”代替

in front of which was a garden.
这里用到了倒装,因为in front of 太长了放在后面不好,
先行词是hotel,表示,in front of the hotel was a garden.
就是这样.比如说,
i won't forget the day on which i joined the army.
这句话,on which i joined the army,表示on that day,i joined the army.
如果搭配联系紧密的话不用倒装.
如,
this is my sister whom i should take care of,不说this is my sister of whom i should take care.这是要注意的.
加油哦!
