He was still there, asleep. Then he woke up too and said, “Hi, you.” “Hi,” I said. “How did you sleep?”

I could summon him when I wanted to talk, but I never knew him in any light other than the one from the lamp by his bed. I could call him any time I liked; I could avoid him any time I wanted, because just one click of the mouse would shut him out of my room.

19. 一天晚上，他说：“我很喜欢你。” “我也很喜欢你，”我说。“可我不知道这意味着什么。” Paras. 8-9 Chinese “I really like you,” he said one night. “I really like you too,” I said. “I don’t know what that means.”

20. I wanted to find out. So in early March I borrowed a car, begged my boss to let me out of work a day early, and drove 540 miles to spend a long weekend in the city where Paul lived. 我想找出答案。于是，3月初，我借了辆车，央求老板准我提前一天放假，驱车540英里到保罗生活的城市，与他共度长长的周末。 Para. 10 Chinese

21. Paul was almost exactly as I expected. He stood waiting at the side of the street while I parked my car. We kissed on the street. I felt relieved and thought: “This works in real life.” 保罗几乎就是我想象的那样。我停车时，他站在街边等。接着我们在街上亲吻。我一边感到宽慰，一边想：“这种事居然发生在现实生活里了。” Para. 11 Chinese

22. But after we kissed and ate pizza and went back to his house, we struggled for things to talk about. In real life, Paul stared off at nothing while I talked. In real life, he had no questions about the drive or my job. He took me out for dinner and read his e-mail while we waited for our food. 然而，等我们接过吻，吃过比萨饼，回到他家，我们却很难找到话题。现实生活里，我说话的时候保罗双眼茫然地瞪着。现实生活里，他对我的旅途或工作闭口不问。他带我出去吃饭，等饭时却自顾自地查看他的电子邮件。 Para. 12(a) Chinese

23. 他带我去朋友家里参加派对，他们一连几小时讨论网络设计，而我则被晾在座椅上，醉醺醺地、无聊地望着天花板。我感到所有这一切就像一场游戏：像在不停地跳舞，他一会儿靠近我，一会儿推开我，在这场舞蹈中，我们一直游离于亲近和疏远、现实生活和虚拟网络之间。他带我去朋友家里参加派对，他们一连几小时讨论网络设计，而我则被晾在座椅上，醉醺醺地、无聊地望着天花板。我感到所有这一切就像一场游戏：像在不停地跳舞，他一会儿靠近我，一会儿推开我，在这场舞蹈中，我们一直游离于亲近和疏远、现实生活和虚拟网络之间。 He took me to a party at his friend’s house where they proceeded to argue for hours about Webdesign while I sat on a chair and stared at the ceiling, drunk and bored. I felt all this seemed like a game: a constant dance of reaching for me and pulling back, of closeness and distance, of real life and Internet make-believe. Para. 12(b) Chinese

24. The day I left him while he was out at work, I wrote him a note, willing myself not to cry: “Dear Paul, thank you so much for having me this weekend. It meant a lot to me to spend time with you in person.” 我离开保罗的那天他上班去了。我给他留了张字条，一边强忍着泪水一边写道：“亲爱的保罗，非常感谢你留我在这里一起度过这个周末，与你在现实生活中共度周末，这对我来说意义非凡。” Para. 13 Chinese
