1 . Some people believe that humans could live on the planet Mars by the year 2100. Our own planet, the Earth, is becoming more and more crowded and polluted. It is hoped that people could start all over again and build a better world on Mars. Here is what life there could be like.
At present, our spacecraft are too slow to carry large numbers of passengers to Mars — it would take months. With the development of technology, by the year 2100, the journey might only take about 20 minutes in spacecraft that travel at the speed of light! However, the spacecraft would travel really fast, so the journey to Mars might be quite uncomfortable. Many people would feel ill.
Humans can’t live without water, air or food. So far, nobody knows whether there would be enough water or air on Mars for people. Moreover, scientists are not sure whether plants could grow on Mars. Food would most probably be in the form of pills (药片) and would not be so tasty.
Compared with life on the earth, life on Mars would be better in some ways. People would have more space. They might live in houses with huge comfortable rooms. Also, robots would do a lot of their work so that they could have more time to relax. There would probably be no schools on Mars. Every student would study at online schools with “e-teachers”.
Life on Mars would be interesting and challenging. However, it may take hundred or years to make it true. So the most important thing we need to do now is to protect our beautiful blue planet — the Earth!

2 . THE TIME MACHINE
It was at ten o'clock today that the first of all Time Machines began its career. I gave it a last check, and sat myself in the leather seat. I pushed the starting lever (操纵杆) on the main panel forwards an inch then immediately backwards again. Looking around, I saw my laboratory exactly as before. Had anything happened? I thought my mind had tricked me. Then I saw the clock. A moment before, it was a minute or so past ten; now it nearly half past three!
I drew a breath, gripped(紧握) the lever and pushed it forwards. The laboratory went hazy around me. My niece came in to fetch something, maybe her handkerchief, apparently without seeing me. It probably took her a minute, but to me she moved like a rocket! I pushed the lever further. Night came as if a lamp was being turned out, and in another moment came the day. Tomorrow night came, then skipped to day, again and again, faster and faster still.
It is hard to explain the strange and unpleasant feeling of time travelling. It felt like I was being driven fast on a winding road. As my pace grew faster, the walls of the laboratory fell away, and I was left in the open air. The sun and moon looked as if they were being thrown across the sky, but soon there was division between night and day. Around me I saw trees growing like puffs of smoke; they grew, spread, and died in moments. I saw huge buildings rise up, then disappear like in a dream. The whole surface of the earth was being changed, melting and flowing before my eyes. I calculated that I was being pushed through time at hundreds of years a minute.
I had a strong urge to look at the random things that were being flashed before my eyes! I had thought about the risk of stopping the Time Machine many times. So long as I travelled at maximum speed, it didn't matter. But if I stopped and the same space was being occupied by something else, we would be forced together and explode like a bomb! Like an impatient fool, I pulled the lever backwards hard. With a sudden jolt, the Time Machine was flipped on its side, and I was thrown through the air.
I was stunned for a moment, and then heard the sound of thunder. I was sitting in the rain in some mud next to the machine. “A fine welcome,” I said, “for a man who has travelled thousands of years to be here!”
(Adapted from the novel The Time Machine written by H.G.Wells, a novelist famous for the science fiction)

4 . When almost everyone has a mobile phone, why are more than half of Australian homes still paying for a landline (座机)?
These days you’d be hard pressed to find anyone in Australia over the age of 15 who doesn’t own a mobile phone. In fact plenty of younger kids have one in their pocket. Practically everyone can make and receive calls anywhere, anytime.
Still, 55 percent of Australians have a landline phone at home and only just over a quarter (29%) rely only on their smartphones according to a survey (调查). Of those Australians who still have a landline, a third concede that it’s not really necessary and they’re keeping it as a security blanket — 19 percent say they never use it while a further 13 percent keep it in case of emergencies. I think my home falls into that category.
More than half of Australian homes are still choosing to stick with their home phone. Age is naturally a factor (因素)— only 58 percent of Generation Ys still use landlines now and then, compared to 84 percent of Baby Boomers who’ve perhaps had the same home number for 50 years. Age isn’t the only factor; I’d say it’s also to do with the makeup of your household.
Generation Xers with young families, like my wife and I, can still find it convenient to have a home phone rather than providing a mobile phone for every family member. That said, to be honest the only people who ever ring our home phone are our Baby Boomers parents, to the point where we play a game and guess who is calling before we pick up the phone (using Caller ID would take the fun out of it).
How attached are you to your landline? How long until they go the way of gas street lamps and morning milk deliveries?

5 . A robot with a sense of touch may one day feel “pain”, both its own physical pain and sympathy for the pain of its human companions. Such touchy-feely robots are still far off, but advances in robotic touch-sensing are bringing that possibility closer to reality.
Sensors set in soft, artificial skin that can detect both a gentle touch and a painful strike have been hooked up to a robot that can then signal emotions, Asada reported February 15 at the annual meeting of the American Association for the Advancement of Science. This artificial “pain nervous system,” as Asada calls it, may be a small building block for a machine that could ultimately experience pain. Such a feeling might also allow a robot to “sympathize” with a human companion’s suffering.
Asada, an engineer at Osaka University, and his colleagues have designed touch sensors that reliably pick up a range of touches. In a robot system named Affetto, a realistic looking child’s head, these touch and pain signals can be converted to emotional facial expressions.
A touch-sensitive, soft material, as opposed to a rigid metal surface, allows richer interactions between a machine and the world, says neuroscientist Kingson Man of the University of Southern California. Artificial skin “allows the possibility of engagement in truly intelligent ways”.
Such a system, Asada says, might ultimately lead to robots that can recognize the pain of others, a valuable skill for robots designed to help care for people in need, the elderly, for instance.
But there is an important distinction between a robot that responds in a predictable way to a painful strike and a robot that’s able to compute an internal feeling accurately, says Damasio, a neuroscientist also at the University of Southern California. A robot with sensors that can detect touch and pain is “along the lines of having a robot, for example, that smiles when you talk to it,” Damasio says. ‘It’s a device for communication of the machine to a human.” While that’s an interesting development, “it’s not the same thing” as a robot designed to compute some sort of internal experience, he says.
