With just a smartphone, people can do almost everything — from studying online to ordering food. However, it also brings some problems if not used properly. A recent survey shows that 70% of students spend over 3 hours a day on their phones. Most of this time is used for playing games or watching short videos. This can affect their studies and sleep. Experts suggest that students should set a time limit for using their phones. For example, they can use apps that track screen time and remind them to take breaks. Another issue is online safety. Many people share personal information carelessly on social media, which may lead to identity theft. It’s important to remember not to share passwords or address with strangers online. Also, being careful with online friends is necessary, as not everyone online is honest. Despite these problems, the Internet is still a useful tool. It helps us study, work, and connect with others. The key is to use it wisely — balance is the most important. 21．What is the main idea of the passage? A．How to make money online. B．The advantages and disadvantages of the mobile Internet.
