Answer 1

分析 我們?cè)跈C(jī)場(chǎng)被耽擱了．不然的話，我們?cè)谖顼埱熬偷竭@里了．

解答 答案：D
根據(jù)題干中的otherwise可知，此句是含蓄虛擬條件句，相當(dāng)于if引導(dǎo)的虛擬條件從句．由謂語(yǔ)動(dòng)詞were delayed可知是過(guò)去的一件事，所以主句的謂語(yǔ)動(dòng)詞形式應(yīng)為would/could/might/should have done．原句可改為If we hadn't been delayed at the airport，we would have been here by lunch．故選D．

點(diǎn)評(píng) 含蓄虛擬條件句常將條件從句隱藏在上下文一定的單詞短語(yǔ)中，常見(jiàn)的提示詞有：with、without、otherwise、or、but for、but等．解題時(shí)，一要抓住這些關(guān)鍵詞的提示；二要確定是對(duì)哪一個(gè)時(shí)間（過(guò)去、現(xiàn)在或?qū)��?lái)）的假設(shè)．如對(duì)現(xiàn)在和將來(lái)時(shí)間假設(shè)，主句的謂語(yǔ)動(dòng)詞形式為would/could/might/should do；如對(duì)過(guò)去時(shí)間假設(shè)，謂語(yǔ)動(dòng)詞則為would/could/might/should have done．
