大全－732由此想到的问题

verb1 + to have done是不是说有“从verb1之前一直延续到verb1”的意思？"to have done"表完成，这个说法是不是说have done的动作在verb1之前完成？

由此得到：verb1 + to have done有两层意思：1) 从verb1之前一直延续到verb1；2)表达done在verb1之前完成。

请NN指教...急...

(A) that are alleged to be worn

(B) alleged to have been worn

(C) that are worn, it was alleged

(D) alleged as having been worn (B)

(E) that are worn, allegedly

大全－748 The fear of rabies is well founded; few people are known to recover from the disease after the appearance of the clinical symptoms.

(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（B)

(E) recovery from the disease is known for only a few people after the clinical symptoms appear

Choice A does not clarify the timing of events but rather suggests that a few people continue to recover indefinitely. In B, the best choice, have recovered and have appeared indicate that the action of recovery is completed rather than ongoing. In choice C, the impersonal construction ( there are ) is needlessly wordy; moreover, the placement of known wrongly implies that the issue is whether the people rather than the instances of recovery are known. Choice D further confuses matters by placing the after phrase well before recovered, the verb it modifies. Choice E is indirect and unidiomatic. The question is of average difficult.

一般的解释都会说在verb1之前完成，如大全－748 的解释；my point is：是否表达了一直延续到verb1，从大全－732来看，有这层意思。但是不是很确定，请大牛出手。

I believe that you have explained it clear enough.
