The change was hardly noticed at first，but it seemed as if the crops were not doing so well. More worrying was that the children fell ill more often，and，there seemed to be more insects around lately.

　　The villagers decided that they couldn't just wait to see the crops failing and the children getting weak. They would have to use the money earned to buy pesticides (杀虫剂) and medicines. Soon there was no money left.

　　Then the people realized what was happening. It was the frog. They hadn't been useless. They had been doing an important job—eating insects. Now with so many frogs killed，the insects were increasing more rapidly. They were damaging the crops and spreading

　　diseases.

　　Now，the people are still poor. But in the evenings they sit in the village square and listen to sounds of insects and frogs. These sounds of the night now have a much deeper meaning.
