选择题
Tough __________ the task was, we _______ finish it ahead of time and therefore we were highly praised for it.
A.though; would
B.although; had to
C.as; were able to
D.though; must
答案
C
题目分析:考查as的倒装句以及固定用法。be able to do sth指经过努力能够做某事;have to指客观上不得不做某事;本题重在掌握as“尽管”时可引起倒装,同时although引导让步状语从句时不能倒装,as引导让步状语从句时必须倒装,而though引导让步状语从句时可以倒装也可以不倒装。句意:尽管这个任务很难,我们还是能够提前完成的,因此我们会因此得到高度赞扬。故C正确。
