How to Improve Your English Pronunciation

    Accurate pronunciation is an important part of learning English, or any language for that matter. The way your speech sounds can have a big impact on whether or not people understand what you are saying and their initial impression of you. There are no shortcuts to perfect pronunciation; there are, however, some ways you can practice more effectively and improve your skills faster.

    It's often difficult to hear pronunciation errors in your own speech because you are concentrating on actually communicating rather than the sound you are making. If you can't hear your pronunciation problems, it's tough to correct them. Try recording your speech with your smartphone or PC and making a note of specific areas you need to improve on.

    Moreover, many English learners think that speaking fluently means they need to speak fast. This is wrong. Speaking too fast reinforces bad habits and makes the speaker sound nervous and indecisive. Speaking slowly will give you time to breathe properly and think about what you want to say next.

    Pronunciation is a physical skill. You're teaching your mouth a new way to move and using different muscles. Focus on difficult sounds each day. Having trouble with "th"? Put your tongue between your teeth (don't bite down) and blow air out of your mouth. Feel the air move over the top of your tongue. Another method worth a try is learning popular English songs. Singing helps you relax and just get those words out, as well as helping your rhythm and intonation (语调). Because you don't need to concentrate on constructing sentences for yourself, you can concentrate on making your pronunciation sound great!

    Over the past few years, there has been a big increase in the number of people sharing information online. In this article we will learn about some positive factors for people to share information online.

    We often share information with our friends in the office or at home to educate, entertain or pleasantly surprise them. In this way we can connect with others. This is also true while sharing information online. If you look at the Facebook wall posts of your friends, you will realize that most of their updates are usually famous quotes, entertaining videos, inspirational images, funny jokes, etc. 94% of those who responded to a survey by the New York Times said they put a lot of thought into how the content they are sharing will be beneficial to others.

    A lot of people share information online to represent their true self to the outside world. Some people, especially those who are shy and not comfortable talking about their areas of interest in the presence of others, find it extremely convenient to share that information online with like-minded individuals.

    78% of the respondents in the study of The New York Times said they shared information online because it helps them develop better relationships. Today, a lot of people do not have the time to meet each other in person and the Internet has become a great substitute. A lot of people now "meet" each other online, rather than in conventional places like restaurants and pubs.

    Lastly, when we share our thoughts online, we are actively engaging with the vast community of people who are a part of the World Wide Web. Sharing information will make a difference to the viewpoint of others, or add to their understanding about the world.

Robotic Exoskeletons

Thanks to robotic exoskeletons, victims of spinal cord (脊髓) injury have a new reason to hope. Robotic exoskeletons, consisting of metal legs, motors, batteries, wiring, a controller and a set of strips work together like the user's bones, muscles and nerves-outside the body. Fastened into an exoskeleton and supported by sticks, users can direct the machinery to take them where they want to go.

In addition to partly restoring mobility, robotic exoskeletons offer the significant mental and physical health benefits of standing up and moving. Just being able to get up from a wheelchair gives patients a more natural, positive view of the world. It also helps relieve pressure on patients' skin and reduces the danger of pressure sores. Standing upright strengthens a disabled person's muscles and bones, improves heart health，and reduces certain other health complications (并发症). And it may actually result in partial nerve repair, something that can only happen when a patient is able to move.

As promising as this technology is, however, it is no simple cure-all for paralysis(瘫痪) or its complications. The motion is not accurate compared with natural walking, and exoskeletons are not easy to use, especially on surfaces that are not smooth. They are very expensive, costing about US$100000. Health insurance plans and government programs may not cover the cost of buying one.

Nevertheless, robotic exoskeletons, and access to them, will continue to improve. As with much modem technology, robotic exoskeletons will likely become more capable and easy to use, even as their cost goes down. Governments and insurers may increasingly see that the health benefits of these walking machines outweigh the costs, making it easier to fund them. Perhaps the day will come when nearly everyone paralyzed by spinal cord injury will be able to "walk" again.
