题目内容
4.We don't allow people to smoke anywhere in the building,(改为被动语态)Peoplearen'tallowed to smoke anywhere in the building.
分析 我们不允许人们在这座楼房的任何地方抽烟.
人们不被允许在这座楼房的任何地方抽烟.
解答 答案:aren't allowed.根据句子中don't allow可知原句为一般现在时,一般现在时的被动语态结构:am/is/are(not)+动词的过去分词;主语是people为复数,谓语动词为allow,又是否定句,故答案是aren't allowed
点评 此题要求把主动语态变为被动语态,做这类题时,首先由原句的谓语确定采用哪种被动语态结构,再看主语,二者结合即可得出答案.
