C I'm really nervous opening Chatroulette （a website）．I don't know if I'm more scared of the possibility of coming face-to-face with a naked （裸体的） guy doing improper things, or the possibility of having to speak to someone normal．But it's that uncertainty that's caused the 'game' to explode into an Internet phenomenon． So, I hesitantly click 'play'．My face appears in a small box to the left of the screen．I'm a 22-year-old guy, wearing jeans and a T-shirt, and sitting in my warmly lit bedroom —not too threatening, I think．Believing I look welcoming and friendly, I open all features: visual, audio and text．The user can disable these at any time if they feel uncomfortable． Quickly I find myself face-to-face with my first 'partner'．A guy with glasses is staring back at me．He looks like he spends too much time in front of the computer．'Hey', I say, 'how are you going?' 'Good,' says the guy．Sensing that he was not going to be very talkative, I hit the 'next' button． Just like that, I'm thrown across the world into someone else's bedroom．This time it looks like a middle-aged woman．I must have hit gold because 85 percent of Chatroulette users are male, according to the Wall Street Journal．She's wearing sunglasses and smiles back．Before I can even say a word, she 'nexts' me．'WHAT?!' Then, I fly through the Internet and arrive at my next partner．My nightmare, a man is sitting in his computer chair half-naked taking off his pants．Argghh! 'Next, next, next!' For the next 30 minutes I keep my cursor （光标） over the 'next' button．My experiences continue to be short, shocking, and largely uninteresting．I discouragingly hit 'next' after seeing another naked man, and decide to end my session and close the window．This wasn't 'the new social media experience' I was hoping for．Maybe it was just a little bit too random （随机的）． 64．It is the author's __________ that leads him into Chatroulette． A．curiosity          B．unwillingness    C．enthusiasm          D．ignorance 65．The underlined word 'disable' in Paragraph 2 means __________． A．store                  B．close                C．misuse                D．copy 66．Among all the partners, __________ seemed to be the least interested in talking with the author.
