week.我昨天給他打電話，問他我下周做什么。比較：“what shall i do next week？” i asked.“我下周做什么？”我問道?？梢哉f，直接引語變成間接引語時(shí)，shall變成了should。2)would也無詞義，是will的過去形式，與動(dòng)詞原形構(gòu)成過去將來時(shí)，用于第二、第三人稱。he said he would come.他說他要來。比較：“i will go，” he said.他說：“我要去。”此句變成間接引語，就成了he said he would come。原來的will變成would，go變成了come。答案：導(dǎo)學(xué)互動(dòng)即學(xué)即練：11)a解析：遺棄對(duì)之負(fù)有責(zé)任者用abandon。2)c解析：句意為：“不要沉溺于觀看足球賽之中”。abandon oneself to“使放縱，沉溺于”，to為介詞。21)a解析：句意為：“
