问题补充：

She didn work hard at her lessons so she failed ________ all the exams.

A.to pass

B.passing

C./

D.A and C

答案：

答案:D

解析：fail是动词，意为“没有能够”，表示“没有做某事”，常用fail to do sth结构，但fail后不能接v. -ing形式，在指某门学科考试不及格时可以说：fail the exam或fail to pass the exam或didn pass the exam或fail in the exam等。因此可判断A、C两项都对，故选D。题意为：她学习不努力，因此她所有的考试都不及格。
