请教新概念4中的一篇课文
32课 Galileo reborn
In his own lifetime Galileo was the centre of violent controversy; but the scientific dust has long since settled,and today we can see even his famous clash with the Inquisition in something like its proper perspective.请问此处为何用has,现在完成时,longsince 是过去完成时的标志.
He had been the frist to turn a telescope to the sky,and he had seen there evidence enough to overthrow Aristotle and Ptolemy together.此处为何用过去完成时?并没有时间状语指示啊.
优质解答
先看第一句：
long since只能说是完成时的标志,不仅限于过去完成时.参见柯林斯例句：
The UN is an organisation which has long since outlived its usefulness.
所以用has没问题.
再看第二句：
因为用望远镜观察天空是old view,参考前文中The old view of Galileo was delightfully uncomplicated一句,用过去完成时是为了与下文的新观点做对比
