“I received two letters from my parents last month．”he said two months ago．He said two months ago that he had received two letters from his parents________．A.last monthB.the last monthC.the month beforeD.the month ago

C解析直接引语改为间接引语时时间状语要改变，这是因为除非转述人是在当天转述，否则原来所说的“今天”，就绝不是“我”现在所说的“今天”了。转述人要以说话人所站位的时间为时间立足点来叙述原来所表达的时间。归纳起来，第一条规则是：把ago改为before，two days ago→two days before(用ago是以现在为立足点，用before是以过去为立足点)，对于不用ago来表达的一些时间状语可以按这个原则：last week→the week before，last month→the month before，另外yesterday(不说last day)→the day before，yesterday motning→the morning before．因此本题中的last month要改为the month before．
