• B． is not allowed

• D． are not allowed

Answer 1

分析 -十六歲的青少年在中國(guó)不允許開(kāi)車．-但在美國(guó)卻可以．

解答 答案：D 根據(jù)--Sixteen-year-olds _______ to drive in China．可知這句話的主語(yǔ)是Sixteen-year-oldst它是謂語(yǔ)動(dòng)詞allow的承受者，故二者構(gòu)成被動(dòng)關(guān)系，所以應(yīng)該用被動(dòng)語(yǔ)態(tài)．對(duì)話是說(shuō)的現(xiàn)在的情況，應(yīng)該用一般現(xiàn)在時(shí)．一般現(xiàn)在時(shí)的被動(dòng)語(yǔ)態(tài)的構(gòu)成：is/am/are+及物動(dòng)詞的過(guò)去分詞．再根據(jù)下文But in America，they can．句中的but 常用來(lái)引出與前文相對(duì)照的詞語(yǔ)，但是在美國(guó)允許開(kāi)車，可知在中國(guó)不允許開(kāi)車．所以應(yīng)該用被動(dòng)語(yǔ)態(tài)的否定形式；又知Sixteen-year-olds是復(fù)數(shù)，動(dòng)詞be用are，變否定句直接在are后加not故填aren't allowed，故選：D

點(diǎn)評(píng) 主要考查被動(dòng)語(yǔ)態(tài)，當(dāng)句子的主語(yǔ)是動(dòng)作的承受者時(shí)，應(yīng)該用被動(dòng)語(yǔ)態(tài)，本題考查的是一般現(xiàn)在時(shí)態(tài)的被動(dòng)語(yǔ)態(tài)的否定形式．一定注意其構(gòu)成形式am not/isn't/aren't+及物動(dòng)詞的過(guò)去分詞
