非典型性肺炎（简称SARS）已经进入了我们的日常生活词汇。这是一种以前不为人知的疾病，而我们现在就生活在它的阴影中。与SARS成为触目惊心的同时，一种由来已久的更具传染性的疾病正在抬起它丑恶的头，那就是惊恐，或曰失去理性的恐惧。
【正确答案】：SARS has entered our daily vocabulary. It is a disease previously unknown to all, but now we are living in its shadows. While SARS has become the center of attention, an ancient and more infectious disease is raising its ugly head. That disease is panic or irrational fear.
