3. Write a paragraph (120-150 words) about the disadvantages of using electronic devices in studying

Sample answer:

Using electronic devices in education is becoming more and more popular, but this can bring some disadvantages. First, learners have to depend on the Internet to search for information or look up new words. Access to Wi-Fi is not always stable and available. Second, electronic devices can easily distract students from their studies. There are too many types of entertainment programmes on the Internet. For example, students may use mobile phones to play games, text and chat during lessons. Third, there are some viruses that can attack students' devices. This may lead to the loss of personal data and documents. In short, to avoid these problems, it is necessary for schools and parents to consider and set certain rues for using electronic devices to study.
