As a fan of online literature, I can't give 30 famous works that middle school students must read because it's an inaccurate and unscientific statement. Masterpieces are usually based on a specific period, culture, and theme. They have a wide readership and far-reaching influence. All readers of different ages should choose to read works that suit their interests and needs. At the same time, masterpieces should not be simply classified as "must-read" or "needn't read" because their value and meaning will vary with time and situation.
