问题 Quizzes are given every other week to make sure that the students ______ keeping in pace with what is going on in the class.
选项 A、are to be
B、will be
C、shall be
D、are
答案D
解析 本题考查动词时态。在that从句中，谓语表示的动作与what从句的动作is going on．．．同时发生，即学生的学习与课堂教学保持同步，所以D是正确答案。A、B、C三个选项都是将来时，应排除。本句中， every other week每隔一星期；make sure确保。这句话的意思是：每隔一周进行的小测试是确保学生的学习与课堂教学同步。
