About writing an introduction +050

Today is a sunny day and a hot day. Cicada kept calling among the dense branches and leaves, as if to say, "It's so hot, so hot." Cicada has been calling, and its song has been reaching my ears, which also makes me fidgety. Suddenly, my eyes lit up and I saw a cicada crawling feebly on the branch, which was very pitiful. I caught the cicada gently and looked at it carefully: it was dark all over and had two big eyes. There are three legs and hooks on my toes, so I can lie firmly on the trunk. It also has a pair of wings, thin and transparent, very beautiful. Cicadas will stay underground for 2- 17 years, then they will break out of the ground, climb up the tree, and shed their shells for the fifth time to grow into cicadas. The molted shell is like its armor, and the cicada shell can also be used as medicine. Cicada also absorbs nutrients from the leaves of big branches, which is harmful to trees. So cicadas are both beneficial insects and pests. Throughout the summer, cicadas have been singing loudly, like an insect musician, singing one brisk cicada song after another for people, adding a joy to nature. However, cicadas can only live for one summer, and their lives will be over when the autumn wind comes. I gently put the cicada back on the branch, let it continue to sing and let it have a happy summer.
