【考试例析】Leave your key with a neighbor _______ you lock yourself out one day.
A. ever since B. even if C. soon after D. in case
中公教育解析： 选D。句中in case 意为"以防万一"，引导条件状语从句。句意"把钥匙留给邻居以防有一天你被锁在门外。"
三﹑让步状语从句
引导让步状语从句的从属连词有although， though， as， while(虽然)，even if / though(即使)，whether ... or ...(不论/不管……还是……)以及"疑问词+ever"和"no matter +疑问词"等。注意：as引导的让步状语从句，意为"虽然，尽管"，从句要用倒装语序。
【考试例析】_______， he talks a lot about his favorite singers after class.
A. A quiet student as he may be
B. Quiet student as he may be
C. Be a quiet student as he may
D. Quiet as he may be a student
中公教育解析：选B。as 引导让步状语从句时，表语、状语等要置于句首；当表语是单数名词时，前面的不定冠词通常省略。句意"尽管他是个安静的学生，课后他谈论很多关于他最喜爱的歌星。"
