Someone's always watching you online...
How do they get my information? Did you know that when you surf the Web, many websites put secret software on your computer? The software collects a large amount of information about you and sends it to Internet companies. The Internet companies sell it to other businesses. Your personal information can also be collected from social media（媒体）sites. There are many ways your information can be used.
What information do they collect and why? First, companies collect your information. The companies find out where you live, what websites you visit, and what you do online. With this information, they can guess other things about you. For example, they can guess if you are male or female, how old you are, and your interests. The companies use this information to decide which advertisements（广告）are best for you. Two people can go to the same website, but they will see different advertisements. For example, someone who likes sports could see an advertisement for sneakers, and someone who like films might see an advertisement for movie.
What do they do with my information? Your personal information could also be sold. Some companies collect information just so they can sell it to other businesses. A business that collects and sells personal information is called a data broker. When data brokers sell your information, a lot of different companies will know your online habits. Then these companies will advertise products or other websites to you.
What online habits are tracked（追踪）? Another way your personal information can be collected is through social media. When your information is on social media, a lot of people can see it. Even if you don't use social media, a friend might post a picture or video of you with your name on it. Pictures and videos can be shared for free on social media, which is one of the great benefits（福利）. However, that same act of sharing could be problem for your own security（安全）. If someone knows too much about you, they can steal your identity（身份）. Then they can buy things online and post messages while pretending（假装）to be you.
Conclusion. All of your online habits can be recorded. Studying people's online habits is big business. Your personal information is very valuable to companies. That is how they know who to send their advertisements to. The Internet reaches almost every corner of the world, but the danger is that your personal information might travel that far, too.
正确的，涂A：错误的，涂B。
1.All businesses collect a large amount of information about you online.
2.People who go to the same website may see different advertisements.
3.Data brokers collect your personal information for money.
4.If you don’t get online, your information will be safe.
5.Your personal information can go anywhere with the Internet.
