题目内容
10．If everyone pours less polluted water into Dianchi Lake，it will be _______．（ ）| A． | deeper and deeper | B． | cleaner and cleaner | ||
| C． | dirtier and dirtier | D． | wider and wider |
分析 如果每个人少倒污水进滇池，那么滇池就会越来越干净
解答 答案：B 根据less polluted water可知，这是两者之间的比较，应该用形容词的比较级形式；又因为water是不可数名词形式，此处意思是"少放脏水，滇池水就越来越干净"；形容词比较级的叠用："越来越…"形容词/副词比较级+and+形容词/副词比较级，故答案为：B．
点评 此题考查形容词的比较级的叠用，注意区分："越来越…"形容词/副词比较级+and+形容词/副词比较级和"越…；越…"the+形容词/副词比较级，the+形容词/副词比较级．
