题目内容
2.You have to pay to park here.(改为否定句)Youdon't have to pay to park here.
分析 肯定句:这里停车必须付费.
否定句:这里停车你不必付费.
解答 答案:don't have.have to 是情态动词,表示"一定、必须",与must可互换使用;本句是一般现在时,变为否定句借助助动词do,所以此处填写don't have,表示"这里停车你不必付车费".
点评 本题是将肯定句变为否定句,have to 要变为否定句或一般疑问句需借助助动词do.最后注意其与must的区别,have to强调"客观",有不得不之意,且可用于多个时态;must侧重"主观",必须、一定做某事,只能用于一般现在时.
