偶的理解是: 1. 六小孩claim的时候(1981,claimed),他们已经见过/甚至一直还有见着(that they had had vision -> to have had);现在,六大人(say)直到现在他们还见着(has continued to appear); 2. Samual Johnson在世的时候(过去,seemed),Caffine没有骚他(bothered -> to bother); 所以,拿掉claim/seem,如果是过去完成就改完成,是一般过去就改现在。 至于那两道黑黑有名的be known to, 偶的理解是: 拿掉be known to, 两个都是现在完成:few ppl have tasted without requesting / few ppl have recovered... 所以如果是be known to, 就要接完成;如果是have been known to,就要接现在(简言之,不能完成接完成,现在接现在) 建筑中....欢迎板砖 |
