(单选题)

The author didn’t finish the reading in class because ( ).

A.he was new to the class

B.he was tired of literature

C.he had an attention disorder

D.he wanted to take the task home

参考答案：C

参考解析：

细节题。根据第一段第一句中的“I was diagnosed (诊断) with a kind of attention disorder”及第二段中作者对Smith老师所说的“the doctor said I have attention problems. I might not be able to do it.”可知，作者没有按时完成阅读任务是因为他患有注意力障碍。这样C项符合。A项指的是他对于真个班级来说是新人。B项指的是他很厌倦文学。D项指的是他想把任务带回家做。故本题正确答案选C。
