The other thing I want to let you know is that instead of having a new problem-set that you'll be assigned this Friday, what we'll do instead is we'll give you some practice problems, and these will be just more of the same type of problems that you saw before but that's another chance to try them out more.

另外一件我想要告诉大家的是,这周五将不会像往常一样,给大家布置新的作业,而是给你们一些练习题，这些题目只是另一些跟原来同样类型的习题,你们应该都已经见过类似的,但这是尝试再次解决这类题目的机会。
