The little sparrow felt a sharp pain and struggled to escape from the operating table, but the medical staff cruelly cut off its tongue. The little sparrow screamed, and its eyes flashed with the light of help, but it had lost the ability to express its meaning. It could only helplessly curl up in a corner and wait for its death. A few days later, the sparrow's body was found on the nearby grass. Its body had already turned stiff, leaving only a blurry face and an incomplete tongue. This story made people think that although humans had powerful technology and strength, they still could not get rid of the respect and cherish of life. Even if it is for our own benefit or for other purposes, we should try our best to avoid hurting and killing lives.
