isn't和doesn't在具体例句中怎么用？

Question

It isn't near the airport. 酒店不靠近机场。
It doesn't have a swimming pool. 没有游泳池。
学习英语进行中...有以上这两句例句，不知道为什么第一句用isn't，第二句用doesn't？
麻烦了..
麻烦解释一下上面两个例句当中isn't和doesn't的区别

Answer 1

行为动词做谓语的否定句，一般现在时要加助动词don't 或 doesn't(主语是第三人称单数),后跟动词原形

系动词be(am,is,are)后跟形容词，副词，名词，动词ing形式或动词过去分词，变否定句时直接在be动词后加not追答

1 near the airport是介词短语做表语

2 have是行为动词，所以用doesn't

Answer 2

isn't (is 的否定式) 既是系动词，又是助动词，“这个词 isn't＋现在分词” 构成过去进行时的否定句，“助动词 isn't＋过去分词” 构成被动语态的否定句。
“doesn't＋行为动词原形” 构成一般现在时的否定句。

isn't和doesn't 的用法相同点： 1）都用在反义问句的结尾部分； 2）主句都是肯定句。不同点： isn't 就 事物属性状态名词提问，doesn't就动作发出者提问。例句：It is right, isn't it? 它是对的，不是吗？ It rains a lot in August, doesn't it? 八月常下雨，不是吗？
