Let’s make good use of it to improve our life.2. 范文示例How to Use the Internet ProperlyThe internet has deeply changed our life. It makes things more convenient, but we must learn to use it in a smart way.First, we can use the internet for study. When we meet difficult problems, we can search for answers online. We can also take free online courses to learn new skills, like drawing or English speaking. Second, the internet helps us keep close to our loved ones. Even if our friends move to other cities, we can chat with them every day or share photos of our life. However, we should not spend all our free time on the internet. Playing online games for hours is bad for our health and wastes time that we could use to read books or play sports. Also, we must be careful with online information—some news is not true, and we shouldn’t believe or share it easily. Most importantly, never tell strangers your phone number, address or school name.In short, the internet is a double-edged sword. If we use it well, it will help us grow better. Let’s use the internet wisely and enjoy its benefits. 展开更多...... 收起↑ 资源预览 当前文档不提供在线查看服务,请下载使用!
