C.were not payingD.will not be paying
A

試題分析:句意:100年之后,人類將會(huì)死于什么呢?如果你認(rèn)為這個(gè)問(wèn)題很簡(jiǎn)單,那么你肯定沒(méi)有注意在生物技術(shù)方面所發(fā)生的變革。本句根據(jù)語(yǔ)境表示動(dòng)作從過(guò)去開(kāi)始一直延續(xù)到現(xiàn)在還有可能繼續(xù)進(jìn)行下去,故用現(xiàn)在完成進(jìn)行時(shí)態(tài),故選A
點(diǎn)評(píng):動(dòng)詞時(shí)態(tài)是高考必考語(yǔ)法點(diǎn),理解各種時(shí)態(tài)的含義,用法是解答本題的基礎(chǔ)。英語(yǔ)中很多時(shí)態(tài)的題目,句中并沒(méi)有明確的時(shí)間狀語(yǔ),需要根據(jù)語(yǔ)境和語(yǔ)義進(jìn)行判斷,這點(diǎn)在平時(shí)的練習(xí)中要多理解和總結(jié),在備考中自己要有意識(shí)的掌握時(shí)態(tài)之間的區(qū)別。
