When placing decorations on the desk, middle school students should choose some items that are both beautiful and practical. The following are some suggestions:

1. Plants: Placing a pot of small green plants or succulents can not only beautify the environment, but also increase air humidity, which is beneficial to learning and life.

2. Books: Place your favorite books on the desk, which can be used as decoration and for easy reading at any time. You can choose some inspirational books, literary works, or professional books related to learning.

3. Photos: Placing photos of family or friends can increase the warmth of the desk and help relieve study pressure.

4. Stationery storage box: A beautiful stationery storage box can keep the desk tidy and is also a decoration.

5. Desk lamp: Choose a desk lamp with a unique shape that can not only provide sufficient light, but also serve as a decoration for the desk.

6. Clock: Placing a simple and stylish clock can help students arrange their time reasonably and improve learning efficiency.

7. Artwork: You can choose some small objects with artistic value, such as ceramics, wood carvings, etc., which can not only enhance the taste of the desk, but also stimulate students' creativity and imagination.

8. Personalized stickers: You can put some of your favorite stickers on the desk, such as anime characters, famous sayings, etc., to increase the personal charm of the desk.

In short, when placing decorations on the desk, middle school students should pay attention to the combination of practicality and aesthetics, and avoid placing too many cumbersome items, so as not to affect the learning effect.
