【解析】

试题分析：通过本文考查学生的词性在语境中的正确运用能力。包括动词的时态，非谓语动词，副词，代词，连词，冠词等。

1.happily 考查副词。 这里用副词修饰前面的动词唱歌。

2.insects 考查名词的复数。insect是可数名词，本句用复数形式表一类。

3.as 考查固定搭配。 be regarded as 意思是：被看做是……。

4.are getting 考查动词时态。 现在是青蛙越来越少了。表示现在的状况用现在进行时，复数名词frogs是主语，所以用are getting，注意get 的变化。

5.on 考查动词的搭配。他们被杀然后放在了餐桌上。put … on the table 意思是：放…….在桌子上。

6.reduction 考查名词。根据句子成分分析可知，这里是名词用作介词宾语。

7.eating 考查省略。 while后的主语和主句主语一致时，可以省略，用动词的-ing形式。

8.to save 考查动词不定式。这里用动词不定式to save表目的。

9.who 考查定语从句的关系词。 69_sell and kill frogs to make money是定语从句，在从句中who做主语，指捕杀青蛙赚钱的人。

10.will be punished 考查谓语动词的时态。这里表将来呗惩罚，用一般将来时的被动语态：will be punished。

考点：语法填空。
