Since the 1930s aircraft manufacturers have tried to build airplanes with frictionless wings, shaped so smoothly and perfectly that the air passing over them would not become turbulent.
wings, shaped so smoothly and perfectly
wings, wings so smooth and so perfectly shaped
wings that are shaped so smooth and perfect
wings, shaped in such a smooth and perfect manner
wings, wings having been shaped smoothly and perfectly so
since 是连词,后面需要另一个完整的句子!!!只有B是
别误导别人 manufactured have tried 已经是整句话了
我指的是since clause+comma,然后后面要带另一个完整的句子,这个就是连词带句子的用法!
这里的since是直接加年份,不需要comma,也就是类似于since 1979 China has been prosperous.和Since+clause+comma有什么关系吗?你本来的话的意思是shaped是整句句子的VERB 但是事实是shaped是这句句子的修饰wings的Vpp.
看清楚是since the manufacturer have tried...., wings so ...shaped that ....句子结构。1930s只是个modifier
什么时候1930s这个名词可以作为modifier不加in了?嗯?sharped是这个句子的后置定语,wings是重新提起名词防止引起ambiguous ,照你的说法,sharp是后面句子的VERB,那么wings可以自己sharp了?嗯?
BE是独立主格结构。主句动词是have tried,就算今天wings那个分句全部拿走,把逗号改成句号。这句话还是一个完整的主谓宾
这边的since是一个介词等于from
你这样确实点醒了我,wings不能shape themselves,应该是shaped做modifier表被动,这样since就不是做连词,wings加这只是避免歧义。感谢讨教!评论我就不删了,这样大家解读的更透彻!
