Who Want to Live Forever?
If your doctor could give you a drug that would let you live a healthy life for twice as long，would you take it?
The good news is that we may be drawing near to that date,Scientists have already extended the lives of flies,worms and mice in laboratories. Many now think that using genetic treatments we will soon be able to extend human life to at least 140 years.
This seems a great idea.Think of how much more time we could spend chasing our dreams，spending time with our loved ones，watching our families grow and have families of their own.
"Longer life would give us a chance to recover from our mistakes and promote long term thinking," says Dr Gregory Stock of the UniversityOfCalifornia School Of Public Health. "It would also raise productivity by adding to the year we can work."
Longer lives don"t just affect the people who live them. They also affect society as a whole. "We have war，poverty，all sorts of issues around，and I don"t think any of them would be at all helped by having people live longer,"says US bioethicist Daniel Callahan."The question is "What will we get as a society?"I suspect it won"t be a better society."
It would certainly be a very different society.People are already finding it more difficult to stay married.Divorce rates are rising.What would happen to marriage in a society where people lived for 140 years?And what would happen to family life if nine or 10 generations of the same family were all alive at the same time?
Research into ageing may enable women to remain fertile for longer. And that raises the prospect of having 100-year-old parents，or brothers and sisters born 50 years apart1. We think of an elder sibling as someone who can protect us and offer help and advice. That would be hard to do if that sibling came from a completely different generation.
Working life would also be affected，especially if the retirement age was lifted. More people would stay in work for longer. That would give us the benefits of age-skill，wisdom and good judgment.
On the other hand，more people working for longer would create greater competition for jobs. It would make it more difficult for younger people to find a job.Top posts would be dominated by the same few individuals，making career progress more difficult. And how easily would a 25-year-old employee be able to communicate with a 125-year-old boss?
Young people would be a smaller part of a society in which people lived to 140. It may be that such a society would place less importance on guiding and educating young people，and more on making life comfortable for the old.
And society would feel very different if more of its members were older. There would be more wisdom,but less energy. Young people like to move about. Old people like to sit still. Young people tend to act without thinking.Old people tend to think without acting.Young people are curious and like to experience different things.Old people are less enthusiastic about change. In fact,they are less enthusiastic about everything.
The effect of anti-ageing technology is deeper than we might think. But as the science advances，we need to think about these changes now.
" If this could ever happen，then we"d better ask what kind of society we want to get，" says Daniel Callahan. "We had better not go anywhere near it2 until we have figure those problems out."

The iPod revolutionized the way we consume music. The iPhone made us crazy for apps. And now the iPad is getting ready to rock our love lives—or at least help improve our search for someone to communicate with. In late May, Skout.com will become the first dating site to launch an iPad application. The free app will be similar to the version that’s already available to phone users: members can enter search criteria, such as age range, gender and physical preferences, and a HotMap will show in real time the locations of active Skout users who fit those criteria. The idea is to help members meet up and see if magic happens. The cool thing about the iPad adaptation, says CEO Christian Wiklund, is that its screen is large enough to let the user view the map while simultaneously chatting and searching through another member’s photos.
David Evans, editor of onlinedatingpost.com, says we can expect to see more innovative technology in a few months after companies get acquainted with the capabilities of the iPad. "What I’m looking for are dating sites that are optimized for the iPad, with features native to the sleek computing device like (touch screen motions such as) pinch, twist, zoom and shake," he says. "It’s the iPad that’s going to enable developers to create entirely new ways to browse, discover and connect with singles."
Steve Odom, CEO and founder of dating site Gelato, which launched last year and includes a live feed of members’ social-media profiles, is redesigning his entire website based on the iPad’s appearance. Profile pictures play a key role in online dating, Odom says, and the iPad gives sites an opportunity to play up the presentation of their clientele. "It’s big, it’s beautiful, and it’s perfect for dating sites," says Odom, who plans to unveil the redesign in June.
Evans predicts that online dating sites will begin to display their content like a magazine, letting users flip through pages of profiles and enlarge photos while simultaneously texting with one or more others. He says there’s also been talk of adding a facial-coding and eye-tracking function that would use a webcam on the iPad to refine suggested matches based on a member’s responses to certain profiles. If you grimace, the profile will fade away; if you smile or if your pupils dilate, similar profiles will be suggested. In other words, some day there could be an iPad app for love at first sight.
According to the last paragraph, a facial-coding and eye-tracking function______.
A:could be used to browse the profile pictures more quickly B:is developed based on a member’s response C:can enable the users to get accurate matches more easily D:could support checking profile pictures and texting at once

Smart Window ? ?Windows not only let light in to cut down an electricity use for lighting, but the light coming through the window also provides heat. However, windows are not something people typically associate with being a cutting edge technology. Researchers are now working on new technologies that enable a window to quickly change from clear to dark and anywhere in between with a flip of a switch. ? ?"It took us a long time to figure out what a window really is," says Claes Granqvist. He’s a professor of solid-state physics at Uppsala University in Sweden. "It’s contact with the outside world. You have to have visual contact with the surrounding world to feel well. " So, windows and natural light are important for improving the way people feel when they’re stuck indoors. ? ?Yet, windows are the weak link in a building when it comes to energy and temperature control. In the winter, cold air leaks in. When it’s hot and sunny, sunlight streams in. All of this sunlight carries lots of heat and energy. And all of this extra heat forces people to turn on their air conditioners. Producing blasts of cold air, which can feel so refreshing, actually suck up enormous amounts of electricity in buildings around the world. ? ?Windows have been a major focus of energy research for a long time. Over the years, scientists have come up with a variety of strategies for coating, glazing, and layering windows to make them more energy efficient. Smart windows go a step further. They use chromogenic technologies which involve changes of color. ? ?Electrochromic windows use electricity to change color. For example, a sheet of glass coated with thin layers of chemical compound such as tungsten oxide works a bit like a battery. Tungsten oxide is clear when an electric charge is applied and dark when the charge is removed, that is, when the amount of voltage is decreased, the window darkens until it’s completely dark after all electricity is taken away. So applying a voltage determines whether the window looks clear or dark. ? ?One important feature that makes a smart window so smart is that it has a sort of "memory. " All it takes is a small jolt of voltage to turn the window from one state to the other. Then, it stays that way. Transitions take anywhere from 10 seconds to a few minutes, depending on the size of the window. The development of smart windows could mean that massive air conditioning systems may no longer need. "In the future," Granqvist says, "our buildings may look different. " |
A:Windows can change from clear to dark to save energy. B:Windows help to save energy by letting light in. C:Windows help to save energy by providing heat. D:Windows enable people to have contact with the outside world.
