首先,我很同意楼上的观点,只是最后的结论不敢苟同,there days before 是三天前,而there days later 是三天后,既然前面已经说了ago----before是相互转换的关系,所以there days before 应变为there days ago,如He said,“My sister was here three days ago,but she is not here now.” →He said that his sister had been there three days before,but she was not there then.
这是直接变为间接,所以间接变为直接就是这样的
