The milk must be preserved at this temperature until it ____.
A.will processB.is processedC.has processedD.had been processed
B

試題分析:考查時(shí)態(tài)語態(tài):until引導(dǎo)的時(shí)間狀語從句,主句用的是情態(tài)動(dòng)詞,從句不能用將來時(shí),用一般現(xiàn)在時(shí),而且milk和process是被動(dòng)關(guān)系,用一般現(xiàn)在時(shí)的被動(dòng),句意:牛奶必須在這樣的溫度被保存,直到被加工。選B。
點(diǎn)評:時(shí)態(tài)的考查要看時(shí)間,如果沒有時(shí)間就根據(jù)上下文把隱含的時(shí)間找出來。這句話的關(guān)鍵是until連接的時(shí)間狀語從句的時(shí)態(tài)問題,還有做時(shí)態(tài)題不能夠忘記語態(tài)問題。
