A policeman was questioning 3 blondes who were training to become detectives． To test their skills in recognizing a suspect, he shows the first blonde a picture for5 seconds and then hides it．
“This is your suspect, how would you recognize him?"
The first blonde answers, "That's easy, we'll catch him fast because he only has one eye!" The policeman says, "Well．．．uh．．．that's because the picture shows his profile．"
Slightly confused by this ridiculous response, he flashes the picture for 5 seconds at the second blonde and asks her, "This is your suspect, how would you recognize him?"
The second blonde giggles, flips her hair and says, "Ha! He'd be too easy to catch because he only has one ear!"
The policeman angrily responds, "What's the matter with you two? Of course only one eye and one ear are SHOWING because it's a picture of his profile!! Is that the best answer you can come up with?"
Extremely frustrated at this point, he shows the picture to the third blonde and in a very testy voice asks "This is your suspect, how would you recognize him?" He quickly adds, "Think hard before giving me a stupid answer．"
The blonde looks at the picture intently for a moment and says, "Hmmmm…the suspect wears contact lenses．"
The policeman is surprised and speechless because he really doesn't know himself if the suspect wears contacts or not． "Well, that's an interesting answer．．．wait here for a few minutes while I check his file and I’ll get back to you on that．" He leaves the room and goes to his ．office, checks the suspect's file in his computer, and comes back with a beaming smile on his face． "Wow!  I can't believe it．．．it's TRUE! The suspect does in fact wear contact lenses． Good work! How were you able to make such an acute observation?"
"That's easy," the blonde replied． "He can't wear regular glasses because he only has one eye and one ear．"
【小题1】Why did the policeman show a picture to the three blondes?

Are you a media addict who would go mad after two hours without TV, friend requests, exciting online games and your mobile – or would you easily survive?
Recently, university students around the world were asked to volunteer in a global experiment called Unplugged. It was designed to see how young people would react if they were asked to observe a total media ban by unplugging all forms of media devices for 24 hours.
Unplugged is being run by Dr Roman Gerodimos, a lecturer in Communication and Journalism at Bournemouth University. The experiment is now over but he doesn’t yet know the full findings. However, during the experiment, Dr Gerodimos said there were already signs of how much the exercise affected volunteers. He said: “They’re reporting withdrawal symptoms(症状), overeating, feeling nervous, isolated and disconnected.” During their 24-hour painful experience, three of the experiment’s guinea pigs had to endure one intrusion(侵扰) from the media: a BBC reporter plus cameraman who followed them around for the day. They were asked to write down 100 lines about their day offline, but of course, they all waited until the next day when they had access to their laptops. Elliot Day wrote: “Today, my whole morning routine was thrown up into the air. Despite being aware of the social importance of the media, I was surprised by how empty my life felt without the radio or newspapers.” From Caroline Scott, we read: “I didn’t expect it, but being prevented from the media for 24 hours resulted in my day-to-day activities becoming so much harder to carry out than usual… I didn’t break out in a cold sweat like our lecturer expected us all to, but it’s not something I would like to do again!” And Charlotte Gay wrote: “I have to say the most difficult item for me to be without has been my mobile; not only is it a social tool, it’s my main access point of communication.”
Earlier in the year, a UK government study found that in the UK we spend about half our waking hours using the media, often plugged into several things at once. And a recent study by Nielson found that on average, US teenagers send and receive over 3,000 texts per month ---that’s about six texts per waking hour. So, with technology continuing to develop at an alarming rate, how much time will you set aside for sleep in the future?
【小题1】What’s the purpose of the first paragraph?

  When scientists set out to explore the roots of human laughter, some apes（类人猿） were just tickled（胳肢）to help. That’s how researchers made a variety of apes and some human babies laugh. After analyzing the sounds, they concluded that people and great apes inherited laughter from a shared ancestor that lived more than 10 million years ago. Experts praised the work, it gives strong evidence that ape laughter and human laughter are related through evolution（进化）.
Scientists have noted that apes make characteristic sounds during play or while being tickled, especially to signal that they’re interested in playing. It’s been suggested before that human laughter grew out of primate（灵长类动物） roots. But ape laughter doesn’t sound like human laughter. It may be slower noisy breathing. So what does that have to do with the human ha-ha? To investigate that, Marina Davila Ross and her colleagues carried out a detailed analysis of the sounds made by tickling three human babies and 21 other primates, apes included.
After measuring 11 features in the sound from each species, they tried to find out how these sounds appeared to be related to each other. The result looked like a family tree. Significantly, that tree matched the way the species themselves are related, the scientists reported online in the journal Current Biology. They also concluded that while human laughter sounds much different from ape laughter, their typical features could have come from the same ancestor.
Panksepp, who studies laughter-like responses in animals but didn’t participate in the new work, called the paper exciting. Panksepp’s own work concludes that even rats produce laughter in response to playing and tickling, with sounds that can hardly be heard by people. Robert Provine, a scientist, who wrote the book, Laughter: A Scientific Investigation, said the new paper showed some important clues, like ape sounds that hadn’t been realized before.

Maybe you’re really busy. Maybe you don’t have much to say. Or maybe you’re just lazy. Not a problem. This free service works by letting you broadcast a group text message to your {fiends’ mobile phones from either your own phone, an instant message or an online form at twitter, com. All your notes are then stored and displayed on your personal profile page on the site, which includes links to your friends’ Twitter pages, a thumbnail picture of your choice, and a short bio. All this is what the new service Twitter can bring you. Just remember to keep it short: posts are limited to !40 characters, and the topic is, invariably, “What are you doing?”

More often than not, it turns out, Twitter’s 100,00 members--twice as many as it had just a month ago, according to Twitter business development director Biz Stone--are simply killing time. Even Presidential hopeful John Edwards is on it, although he seems to be the only one thinking about more than lunch. As I type this, Caroline is mulling over some Girl Scout cookies, Ian Hocking is “waiting for Jessica to arrive so we can eat!” and Hlantz is “having a nice cup of Soft Starmint tea.”

The chatter (闲话) about Twitter turned into a virtual roar two weeks ago during the South by Southwest Multimedia Festival in Austin, Texas, when the barebones service owned by Blogger founder Evan Williams, 34, was named the best blogging tool and attendees used it to meet up at parties. Nevertheless, Twitter has been the top term on blog search engine Technorati for the past two weeks.

Plenty of people would happily have Twitter silenced, rather than tolerate the beeping alert for yet another new text message. But I’m betting that Twitter will get a lot noisier before netizens move on to the next new thing. We cyberjunkies need a new thrill, and what is better than a service like Twitter that combines social networking, blogging and texting? And if you don’t like it, well, in the words of one Twit from San Francisco, “I’m so sick to death of Twitter-haters. If you don’t like it, why waste your time writing, reading, or talking about it?”
