Reading has been an important human activity for a long time. Just 50 years ago, most people had to buy physical books to read. However, nowadays, some people prefer reading e-books instead of traditional paper books.
　　　E-books are convenient. They can be read on devices like smartphones, tablets, or e-readers, offering several advantages. People can carry thousands of books on one device, making it easy to read anytime, anywhere. E-books also allow users to adjust the font size or brightness, making reading more comfortable. In addition, e-books are often cheaper than printed books, and some can even be downloaded for free.
　　　However, there are some downsides. Staring at a screen for a long time can cause eye strain, and some readers miss the feeling of holding a physical book. Additionally, e-books depend on technology, so without a charged device or access to the internet, reading might be difficult.
