If you go out to the fields at night in spring or summer, you can hear frogs singing(joy) here and there. It seems as if they were performing a field symphony(交响乐).
The frog is a good and useful creature that benefits human beings. They can catch fast-moving insects. Each frog eats a large number of pests that are (harm) to crops. This little creature is regarded “the natural enemy of pests”.
now frogs are getting fewer and fewer. This isthey are killed and put on the table as a delicious dish by their chief enemy, human beings. It is a shameless and cruel act, isn't it? Another reason responsible for the rapid reduction of frogs is farmers use insecticides (杀虫剂) to kill pests and frogs get (kill)as a result of drinking poisoned water or eating poison-killed insects.
Something must be done without delay (save) frogs. If we don't punish those sell and kill frogs to make money, then one day all of us (punish) by nature for failing to keep the balance of nature.
