Today let’s talk about social networking. First let’s talk about networks. Networks get things done. Whether it’s sending a letter or lighting your home. Networks make it happen. To get from Chicago to Santa Fe, we need to see the network of roads that will get us there. We see that Chicago is connected to St Louis, which is connected to Dallas which is connected to Santa Fe.
    Of course, people networks can help us with finding jobs, meeting new friends, and finding partners. You know how it works. Bob is your friend, he knows Sally, and Sally’s friend Joe has a job for you. This is a network of people—a social network. The problem with social networks in the real world is that most of the connections between people are hidden. Your network may have huge potential, but it’s only as valuable as the people and connections that you can see.
    This problem is being solved by a type of website called a social networking site.[24]These websites help you see connections that are hidden in the real world. Here’s how it works. You sign up for a free account and fill out your profile. Then, you look for people you know. When you find someone, you click a button that says, "Add as Friend". Once you do this, you and that person have a connection on the website that others can see.
    They are a member of your network, and you are a member of theirs. What’s really cool is that you can see who your friends know, and who your friends’ friends know. You’re no longer a stranger, so you can contact them more easily. This solves a real world problem because your network has hidden opportunities. Social networking sites make these connections between people visible.
    Like a map for a highway, they can show you the people network that can help you get to your next destination, whether it’s a job, a new partner, or a great place to live. Your network is suddenly more useful. You can get started at these sites, LinkedIn, Facebook, and MySpace.
23. What is the problem with social networks in the real world?
24. How can the social networking sites solve the problem of social networks?
25. What is cool about the social networking websites?
选项 A、These networks do not have huge potential.
B、Most connections between people cannot be seen.
C、People do not know how social networks work.
D、Networks are not as valuable as the people you see.
答案B
解析 录音提到，在现实世界的人际关系网络存在一个问题，就是大多数人与人之间的联系是隐蔽的(hidden)。因此B项“大多数人与人之间的联系是不可见的”为正确答案。录音提到，你的人际关系网络可能有巨大的潜力，但只有当你看得到人际网络里的人或人际联系，它才会变得有价值，因此A项“这些人际关系网络没有巨大潜力”和D项“人际网络不如你见到的人那么有价值”都不正确。人际网络可以帮助我们找工作，认识新朋友和寻找伴侣，人们能知道它如何起作用，C项“人们不清楚人际关系网络如何起作用”与录音相反。
