With the popularity of 3D movies over the past several years , there was no doubt that the technology would make its way into our homes, The question is: Is it really a technology that is going to stay with us , thus deserving an upgrade at this time? Many families have recently bought a new TV set, and the idea of changing it just to take advantage of a technology in its infancy will put many people off the idea. Then there are the additional costs that come along with a 3Dset from needing to get a Blu-ray player that can process the signal to purchasing enough glasses for the entire family to be able to watch a program at the same time. Another issue is that the glasses are expensive as well as complicated, and have also been known to cause headaches, none of which makes for a pleasant experience. While manufacturers are working towards glasses-free technology, it just isn't here yet, and it could be several years before it is commercially successful. That is one of main things that will keep 3D completely in the "fashion" zone for the time being . If the television manufacturers are willing to hold onto the idea until glasses-free choices are available--and they can reach a higher installed user base--this might very well catch on. Everyone needs to remember, however, that these are businesses, and they are in it to make money. If 3D isn't selling at the rate they are comfortable with, then they will dump it and move on to the next thing. Many homes are filled with products that didn't catch on rapidly and companies ended up leaving them with no support. Do you have an HD DVD player? Remember how the MiniDisc was supposed to replace the CD? For now, it's easy to see how 3D televisions could join this list of technologies. There is one _ to the 3D television problem: They have beautiful 2D images. Even if 3D goes away, you still have a great -looking screen and beautiful images. If you are in the market for a new TV and you can afford to drop the couple extra hundred dollars to buy one, you can view it as... The examples of the HD DVD player and CD are to show _ . A) they are not necessary B) they are bound to be replaced C) 3D TV might not be here to stay D) 3D technology needs improving

There is a forgotten player in the global efforts to limit C02 emissions:the consumer. Households consume one--third of the final energy used in the European Union and produce around two--thirds of city waste.Moreover,food,housing,and private transport account for almost 80%of environmental pressures.So consumers can make a real difference when it comes to fighting climate change. Several factors can direct consumers towards more environmentally--friendly behavior. To achieve this,we need clear and simple information to guide consumption decisions. Indeed.Two thirds of consumers find it difficult to understand which products are better for the environment when shopping. With 58% of Europeans believing that many companies pretend to be green in order to charge higher prices, industry has a long way to go in helping consumers feet confident when making green choices.They should give consumers more information about the carbon footprint of their products,and promote more sustainable behavior among their customers. To be sure, companies are increasingly creating product labels that help consumers make responsible choices--for instance, reminding users of products made from materials that are recycled,renewable, and/or less carbon--intensive. Even so,only,20% of Europeans believe that companies are doing enough to promote environmentally friendly options. In times of crisis, consumers prefer high-quality products that will last long and won't go out of style.Durable products might sometimes cost more, but they don't need to be replaced as frequently. In this way,companies that create durable or recyclable products enable consumers to think differently about their purchases, which can help users behave more responsibly, and thus may help end our "throw-way" culture. However, it is not enough to inform consumers of the environmental features of products. We also need to provide consumers with guidance to establish a practical lifestyle model to follow. This cannot be brought about by regulations alone, but by... According to the passage, the key to going greener globally is _ . A) to get the government involved in protecting the environment B) to require the companies produce environmentally-friendly products C) to encourage consumers to make their efforts to live a green way D) to provide enough information about sustainable products

World's Best Places to Visit We hope the following places can help you choose where to go on your next vacation. Zurich From swimming in Lake Zurich in summer to skiing the Alps in winter, Zurich attracts visitors year-round. As a fairytale city, Zurich is set on the banks of both a river and a lake, with the snow-topped Swiss Alps rising in the background. Clean cobblestone streets hug a hilly land and medieval church tops reach heavenward. Despite its reputation for being the center of old-school international banking and a capital for chocolate, Zurich is also a very modern city that chooses to enjoy life at an unhurried pace. Travelers desiring a real experience should strive to do the same. The City of Angels The City of Angels, the Entertainment Capital of the World--Los Angeles needs no introduction. But its notoriety both helps and hurts its reputation. The traffic on the "101" will tire you out just as much as an evening at a lively West Hollywood club. And your dislike at the thick smog over the city will ruin your enjoyment of a sunset overlooking Santa Monica Beach. To appreciate Los Angeles, visit the area more than once and get advice from locals. Prague A prosperous and busy city, Prague now attracts more tourists than ever. But its picturesque downtown veils both a dark legacy and a resilient past; in its 1,100 years, Prague has survived numerous overthrows, invasions, fires and floods. It's this reputation for survival and perseverance that has made the Czech capital so fascinating. Today, its storied churches, narrow streets, hilltop castle and statue-lined bridges create the scene of an urban fairy tale. Even the most tired traveler would have trouble resisting this city's charms. Puerto Rico Pick a vacation experience you're looking for, and Puerto Rico can help.
