Ms. Miller is strict _____ her students and also strict ______ her work。
本题考查固定搭配。句意：米勒老师对她的学生要求很严格，对她的工作要求也很严格。根据be strict with sb.和be strict in sth.的固定搭配可知答案为A。
It's a _____ talk. I feel ______ when I talk with them.
本题考查boring和bored的区别。第一空表示“令人厌烦的”，要用boring修饰talk;第二空表示“感到厌烦”，用bored，故答案为C。

easy意为“容易的”；different意为“不同的”；difficult意为“困难的”；cheap意为“便宜的”。根据本题语境可知，英语很难，我学不好它。故所缺的词是difficult，答案为C。
