the man had a newspaper open in front of him.
这里有什么语法嘛?
1)have +过去分词,构成完成时态,例如:He has left for London.他已去了伦敦.By the end of last month,they had finished half of their work.上月未为止,他们已经完成工作的一半.2)have + been +现在分词,构成完成进行时,例如:I have been studying English for ten years.我一直在学英语,已达十年之久.3)have+been +过去分词,构成完成式被动语态,例如:English has been taught in China for many years.中国教英语已经多年.
