30、hough 可以独立用作副词，常放在句末，意为“还是；仍然；可是；然而”。(3)as 引导让步状语从句时必须用倒装，though 引导让步状语从句时可以倒装也可以不倒装，而 although 从句则不能倒装。运用用上面的辨析词填空(1)_ he had only entered the contest for fun,he won the first prize.(2)She promised to phone.I heard nothing,_.(3)Talented _ he is,he is not yet ready to turnprofessional.Although/Thoug
