Translate the paragraph into Chinese.Social networking sites are an important part of life in the US. About two-thirds of American adults online use social media platforms such as Facebook, Twitter, MySpace or LinkedIn. Connecting with family members and friends is a primary consideration in their adoption of social media tools. Some media users go to these sites in order to stay in touch with current friends and family members, while others try to connect with old friends they’ve lost touch with. Sharing hobbies or interests, making new friends, reading comments by public figures and finding potential romantic partners are also among the reasons for using social networking sites. Social networking sites can also serve as information networks where people share information with other users. Instead of searching through a news source such as the website of The New York Times or ESPN that caters to all people, a person can check their Twitter account and find out about their favorite team’s scores and news.
