(目的状语从句)‎ Jack is badly ill so that he has to rest. (结果状语从句)‎ n ‎ 让步状语从句 ‎(1)让步状语从句通常由although, though等连词引导。例如：‎ Though he is young, he knows a lot.‎ Although I am tired, I must go on working.‎ ‎(2)although(though)与but不能用在同一个句子中。例如：‎ 我们不能说：Though it was raining hard, but he still went out.‎ 应该说：Though it was raining hard, he still went out.或It was raining hard, but he still went out.‎ 历年中考题： ‎ ‎( )1. _____ Switzerland is very small, _____ it is the land of watch and it is very rich. （2009·湖北孝感）‎ A.
