答案与题解：
1.D 第一段后半部已经列出了包括有A、B、C三个选项的各种症状(还包括有fast heartbeat)，就是没有D项(低血压)。
2.C 第二段第一句说到more than two million，C项的above与more than同义，其他各项均是错误的。
3.B 第二段第二句说“女人患惊恐性障碍的可能性比男人高两倍”，也就是B项说的“是三倍”。这里涉及到英语倍数的理解和表达问题，如果形容词或副词用比较级就应是“比……多出(或高出)……倍”，如果是用同级比较“as…as"则是“是……的……倍”。
4.B 第三段第二句提到马里兰州的切萨皮克湾大桥吓坏开车的人是出了名的，其他地方没有提到。应该注意的是，本题所问的是most likely(“很可能”)，并不是the most likely(“最可能”).因此并不涉及四个选项所列场所进行比较的问题。
5.A 第四段中间两句已经罗列了包括B、C、D三项在内的各个病种，但就是没有A项的“癌症”。
