(A) few people are known to recover from the disease after the appearance of the clinical symptoms (B) few people are known to have recovered from the disease once the clinical symptoms have appeared (C) there are few known people who have recovered from the disease once the clinical symptoms have appeared (D) after the clinical symptoms appear, there are few known people who have recovered from the disease (E) recovery from the disease is known for only a few people after the clinical symptoms appear 答案是B,可是我觉得在陈述一个一般现象时A 的用法也行啊,倒是觉得B中的once the clinical symptoms have appeared 不如after the appearance of the clinical symptoms来得准确啊
