高一英语（牛津版）填关系词（或介词+关系代词）The wrong you have done him is terrib

for which As
这两个题中都用到了非限制性定语从句.(那个逗号就是标志.)非限制性定语从句用which或as引导,其中只有as可以放在句首.as有"正如"的含义,用在句2中很合适.
两句中的先行词均代一个句子.1中which代"The wrong you have done him is terrible","由于这个原因你应该向他道歉",所以采用了介词for.2中as代"over one hundred people were killed or injured in that accident.""正如报道所说,超过一百人在那场事故中死亡或受伤."
需要强调的是.why不能引导非限制性定语从句,所以1不能用why引导.
