问题补充:
单选题Afterhewaspromotedtothepresentposition,heisnotsohardworkingashe______.A.was used toB.used to beC.was used to beingD.used to
答案:
B解析考查的是不定式的省略。as后面引导的是比较状语从句,且该从句存在省略,即:he is not so hardworking as he used to be hardworking= he is not so hardworking as he used to be。句意:在他被晋升到目前的职位后,他不再像他过去那样勤奋了。
