Each week, for example,a record of the sales results of the preceding week for each sales office and for the Sales Department as a whole for each division of the company is kept and compared to the sales results for the corresponding week of the year before.
想请教各位老师，句中
for each sales office
for the Sales Department as a whole
the sales results for the corresponding week 为何是用for 不是of？
谢谢老师解答!
for each sales office 和for the Sales Department as a whole 之所以用for,是由于这两个部门是修饰sales results的，但被the preceeding week隔开了，而这两个部门和 the preceeding week并无所属关系，所以不可以用of,改用for.
the sales results for the corresponding week 这是由于corresponding +时间的结构习惯上介词多用for或in.如：for the corresponding month. 但 of the previous /last month.
