【文章內(nèi)容簡介】 has surely changed over the last two decades.在英國,飲食文化肯定正在不斷地發(fā)生著改變,并且在過去二十年中肯定已發(fā)生過不少變化。2.Now that she is out of a job, Lucy______going back to school, but she hasn’t decided yet.A.had consideredB.has been consideringC.consideredD.is going to consider分析:B。根據(jù)but she hasn’t decided yet (尚未決定)可知,從開始失業(yè)時(shí)起一直在考慮再去上學(xué),現(xiàn)在還在考慮。表示從過去某一時(shí)刻開始一直到現(xiàn)在,并且現(xiàn)在依然在發(fā)生的動(dòng)作,用現(xiàn)在完成進(jìn)行時(shí),現(xiàn)在完成進(jìn)行時(shí)由“have/has been doing”構(gòu)成,所以選B。3.I won’t tell the student the answer to the math problem until he______on it for more than an hour.A.has been workingB.will have workedC.will have been workingD.had worked分的:A。has been working為現(xiàn)在完成進(jìn)行時(shí),是許多中學(xué)生不太熟悉的一種時(shí)態(tài),因此要想通過分析句子直接從正面選出答案可能有一定困難。但是,如果我們用排除法來分析,則問題變得很簡單:首先,由于until引導(dǎo)的是時(shí)間狀語從句,根據(jù)“主將從現(xiàn)”原則,當(dāng)主句為將來時(shí)態(tài)時(shí),時(shí)間狀語從句不能直接用將來時(shí)態(tài)來表示將來意義,據(jù)此可排除B和C。而選項(xiàng)D為過去完成時(shí),也不能選,因?yàn)椤斑^去完成時(shí)”必須以“過去”為支點(diǎn),表示“過去的過去”,但此句并沒有過去時(shí)態(tài)這一支點(diǎn),故此選項(xiàng)也被排除。4.Cathy is taking notes of the grammatical rules in class atSunshineSchool, where she______English for a year.A.studiesB.studiedC.is studyingD.has been studying分析:D。根據(jù)句中的現(xiàn)在進(jìn)行時(shí)可排除B,再根據(jù)句中的for a year可知此題選現(xiàn)在完成進(jìn)行時(shí)最佳,即選D。5.—I have got a headache.—No wonder. You______in front of that puter too long.A.workB.are workingC.have been workingD.worked分析:C。由于在電腦前工作太久,所以導(dǎo)致了現(xiàn)在頭痛的結(jié)果,故空格處應(yīng)填現(xiàn)在完成時(shí)或現(xiàn)在完成進(jìn)行時(shí),即答案選C。6.—I’m sure Andrew will win the first pr
