今天要學(xué)的詞組是backup

作為形容詞，backup的意思是后備，替代。

媒體報(bào)道說，布什總統(tǒng)實(shí)施新的伊拉克計(jì)劃之后，一些州長在白宮詢問布什和參謀長聯(lián)席會(huì)議主席Peter Pace有沒有后備計(jì)劃，"A group of governors asked President Bush and chairman of the Joint Chief of Stuff Peter Pace about their backup plan for Iraq."

州長們后來說，他們認(rèn)為白宮并沒有后備計(jì)劃。許多人認(rèn)為伊拉克計(jì)劃很可能失敗，政府必須要有后備的戰(zhàn)略， "The United States must have backup strategy for Iraq."
