15. You can’t imagine _________ when he learned he failed the exam again.
A. how he was disappointed     B. how disappointed he was
C. how disappointed he is     D. how excited he was
【答案】B
【解析】句意：你不能想象当他了解到他考试又不及格时他有多失望。考查感叹句和时态。根据句意可知，他多么的失望，以how引导的感叹句的格式是how+形容词/副词+主语+动词，所以排除A。然后根据failed the exam again，可知又一次考试失利了，应该是很失望，排除D，然后看时态failed和learned都是过去式，所以是一般过去时，故选B。
