　　三、ACT阅读细节题相关真题解析

　　That is astonishing news about a disorder that usually makes headlines because it seems to be growing rapidly more widespread. In the United States，the diagnosis of autism spectrum disorders has increased about tenfold over the past two decades, and a 2003 report by the Centers for Disease Control suggests that as many as one in every 166 children is now on the autism spectrum, while another one in six suffers from a neurodevelopmental delay. This explosion of cases has raised countless questions: Is the increase real, is it the result of increased awareness and expanding diagnostic categories, is it due to environmental changes, or all of the above? There may be no single answer. But the public concern about autism has caught the ear of federal lawmakers. The Combating Autism Act, approved last December, authorized nearly $ 1 billion over the next four years for autism-related research and intervention.

　　According to the passage, over the past twenty years, the diagnosis of autism spectrum disorders in the US has increased about:

　　A、5 times.

　　B、166 times.

　　C、10 times.

　　D、6 times.

　　解析：这就是一道细节题，答案对应原文中的一句话“In the United States，the diagnosis of autism spectrum disorders has increased about tenfold over the past two decades,”可见，是“tenfold”，也就是十倍的意思，所以选择C选项。
