Please leave Mike to solve the problem by himself.留下某人做某事,不定式表将来,不需要加S.
有问题继续提问,望采纳!题目上写着说这句话有errors in formal,standard usage把你的题目说一下Proofread and correct the errors in formal,standard usage in the following sentences,as in the example given.Example:Why don't(被划去了，改成doesn't）Guadalupe try out for the team.leave sb to do sth是个固定词组，我觉得题目中指的是这个错误
