is are isn't aren't any some
(1) — How many students ______ there in the playground?

(3) — ______ there ______ apples in the basket?
— No, there ______.

(1) are；are
(2) Is；isn't
(3) Are；any；aren't
(4) any；are
(5) isn't；any

(1) 第一空根据“How many students”可知是复数形式，所以使用“are”；第二空根据“There”及“50”可知是复数形式的“there be”句型，所以使用“are”。
(2) 第一空根据“there a TV”可知是单数形式，所以使用“Is”；第二空根据“No”可知是否定回答，所以使用“isn't”。
(3) 第一空根据“there”及“apples”可知是复数形式的疑问句，所以使用“Are”；第二空在疑问句中通常使用“any”表示“一些”；第三空根据“No”可知是否定回答，所以使用“aren't”。
(4) 第一空在疑问句中通常使用“any”表示“一些”；第二空根据“Yes”可知是肯定回答，且“flowers”是复数形式，所以使用“are”。
(5) 根据“I'm thirsty”及“water in my cup”可知杯子里没有水，且“water”是不可数名词，所以使用“isn't any”。
