Question

【题目】Anyway, we're here now, so let's ___some serious work.
A.come up with
B.get down to
C.do away with
D.live up to

Answer 1

【答案】B
【解析】句意: 总之，我们现在到这儿了，所以该我们着手做些正经事儿。come up with"想出(计划、回答),做出 (反应),产生"; get down to "着手做"；do away with"废除， 消灭，去掉, 涤除, 搞掉"; live up to"达到高标准,不辜负,实行,履行"。 因此B选项正确。
