四、阅读理解。
The Internet has changed our life a lot. It is very important in our daily life. It helps us learn new skills in many ways—we can take online courses or read e-books whenever we want. We can also search for useful information for our study and work. Besides learning, it keeps us connected to friends and family easily: we can have video chats and send emails to stay in touch. We can also use the Internet to do shopping, book tickets, and do banking online. It makes our life much easier and more convenient.
However, the Internet is not perfect. Spending too much time in front of the screen is harmful to our health. What's worse, some people may steal our personal information online. We should be careful when we use the Internet, and learn to use it in a smart and safe way.
