The first pulsar,or rapidly spinning collapsed star, to be sighted was observed in the summer of 1967 by graduate student JB,but the discovery was not announced until February 1968.
请问下为什么是to be sighted
为什么不直接用sighted
参考了下Ron神的解释,这里主要有两点原因:
1. Noun to be verb-ed表示 human efforts/actions/interference/perception/etc.等的结果,而 noun verb-edinherent qualities of the noun;
2. 直接copy,理解了半天,很tricky!
the word 'sighted' means 'having the sense of sight', so this sentence also contains the amusing alternative interpretation of referring to a pulsar that can actually see.
