(A) few people have been known to have tasted it (B)few having been known to taste it (C)it has been tasted by few people (D) few people have been known to taste it（D） (E)few people having tasted it
本题答案在AD之间，但究竟该不该用完成时，没有定论，贴下2个NN的讨论：
1、A)few people are known to recover from the disease after the appearance of the clinical symptoms. We say "SUBJECT is known TO HAVE RECOVERED" not "SUBJECT is known TO RECOVER." We wouldn't say he is "known to eat twenty apples". The present tense infinitive (to eat) is wrong. Correct is that "I am known to have eaten 20 apples", which correctly uses the present perfect to imply this is what we've known from the past into the present.
2、(A) few people have been known to have tasted it PROBLEM: "have been known to have tasted it" repeats the present perfect form instead of using the infinitive, which is what we want here. After "have been known", we just want the infinitive form ("to taste"). It would be like saying "I like to have run" instead of "I like to run".
