以下是引用brunhild在2003-11-8 18:34:00的发言: 张道真说得没错,但对照来看看A项,TASTE 是发生在KNOW前吗? 那意思岂不是变成了“吃了以后才知道?” 但这里要表达的是“他们已经知道了吃”! 不定式的过去式在意思上去正常过去式或完成时是相似的,所以有一个方法 将不定式部分变成从句 例如这句few people have been known to have tasted it =few people have been known that they have tasted it !" 说不通吧
再如LZM的这个例子,few people are known to have recovered from disease once the clinical symptoms have appeared=few people are known that they have recovered from disease once the clinical symptoms have appeared. 这句从句里有明显的完成时标志,加上就这句原意思来说无可后非。
大家指教!
