Question

Miss Li is teaching ___________the classroom and I am sitting ________ my friend.
A. in front of; in the front of      B. behind; in the front of
C. in the front of; behind

Answer 1

C

试题分析：in the front of在范围之内的前部，behind在…的后面；句意：李老师正在教室的前面上课，我坐在我朋友的后面。故选C.
点评：in the front of在范围之内的前部，in front of表示在范围外的前面，这两个短语是中学英语常考的结构，学生在平时学习时要进行积累记忆。诸如此类的还有很多，如in在…里面,on在…上面,beside在…旁边。
