What is a good topic for the composition on electronic products?

If it is an exam composition, it is generally not recommended to take too big a topic (such as "On XXXXXX", unless it is a propositional composition). It is usually recommended to use a more grounded title.

You can try to use the words "My life has changed quietly" or "Living in the cloud", and the general content can be written about how XX electronic products have affected my living habits.

If your writing style is good, you can also try to write a relatively conceptual system, such as "intelligent platform", "Internet of Things", "wearable device" or "cloud". The idea of multiple electronic products working together under one platform is relatively novel, and the final conclusion is that modern technology serves people.

If the control ability is not strong enough, it is recommended to write only one device, which is not easy to digress. It is suggested to find some niche products to write, such as electronic paper books or smart bracelets or even XBOX, which is better than writing smart phones. Because too many people use and write smart phones, it may not attract much interest from readers (or marking teachers) unless you are sure that you can write better in language or content.

In addition, pay attention to this article, don't write too "technical" and make it too difficult for liberal arts students (teachers) to read. If you quote some uncommon terms, you'd better add more popular explanations (at this time, you can use some image comparisons or metaphors, or you can add highlights to your composition).
