Difficult _______ the problem is,we should try to work it out.A.however B.as C.although D.tha
答
B as
答
b as 在这里 as引导让步状语从句 译为虽然...但是 当as有这种用法时，有表语 表语提前 ， 没有表语状语提前，没有状语，谓语提前。例如 chilid as he is ,he can still solve this prolbem . hard as he worked, he still failed the exam
答
选择B：as
此处考察倒装句式.由as引导的形容词在前,故选择B
