题目内容
20.In Switzerland,the government doesn't allow people to cut down trees.(改为被动语态)In Switzerland,peopleare not allowed to cut down trees.
分析 在瑞士,政府不允许人们砍树.
解答 答案:are not allowed.结合原句allow sb to do sth允许某人做某事,主语people是动词allow的承受者,构成被动关系,结合时态用一般现在时的被动语态am/is/are+过去分词,主语是复数,故are,加上not表否定,故答案是are not allowed.
点评 一般现在时的被动语态am/is/are+过去分词的呈现,各种类型的被动语态的构成要理解掌握.
