I learned many idioms by reading the book "Little Honey Circle Comic Idioms", such as "One chicken flies, one egg hits", "It's crooked", "The blind man touches the elephant" ... Among them, the idiom "sitting on a well and watching the sky" is the one I remember the most.

The frog in the story may not have thought that the dry well it is proud of is actually so small, nor did it think that there is an endless sea and an endless sky outside its "small world" ... The frog didn't know that his vision was so narrow and his mentality was so complacent.

The idiom "sit on a well and watch the sky" reminds me of some students who "don't listen to things outside the window, just read sage books". In fact, there are such classmates around us. However, they were wrong. It is not enough to have some knowledge of death in a good optics class. We should read more extracurricular books that are beneficial to us, which is very helpful to improve our writing level.

Reading more newspapers and magazines can also enrich our extracurricular knowledge and let us know the current hot topics ... If we only study the knowledge in class, our eyes will be too short-sighted. Isn't that a real frog in the well?
