Ví dụ: Electronic devices are increasingly applied in classrooms. Personally, I support the use of these devices in learning because of several advantages they can bring about. First, electronic devices help students learn better. There are many useful learning applications on smartphones, computers or tablets such as dictionary, pronunciation, and recording. These applications allow students to check their effort immediately and learn from the mistakes. In addition, students can relax and communicate with their friends at break time. Students relax by listening to music, playing games and chatting with their online friends between lessons. This helps them feel comfortable and excited about the next lesson. Finally, electronic devices help save time and make students' backpacks lighter. They let students look up information more quickly. They can store huge amounts of data, so students do not have to bring so many textbooks on their back. In short, the use of electronic devices in the classroom should be encouraged as they benefit students a lot.
