Great speakers are not born but made. You too can become a good orator by taking up the public speaking courses. Those who are incapable of speaking in front of the public can't come up in their life. The art of public speaking must be practiced by everybody who wants to reach great heights in their career. A lot of public speaking courses are available on the Internet. Choosing the best course that is right for you may be difficult but not impossible.

    The basic motive of public speaking courses should be to train you to become a public speaker and improve your skills of delivering a public speech. The course should first educate you with the principles of public speaking and tell you how to overcome stress and anxiety. By overcoming fear, you will be able to deliver your presentation clearly to your audience.

    A speaker can have a great influence on the audience with his body language and your public speaking course should tell you the gestures on stage that can attract the audience. Non-verbal communication also has a major role to play in delivering a speech effectively to a group. Though body language is important, the content and the natural use of words are what the audience are closely caring about. Public speaking courses should give tips in using the right words at the right time.

    Even though you have prepared well, the real success of public speaking lies in the way your speech is delivered. Public speaking courses will train you to present the contents in a lively manner impressing the audience. Your presentation should be professional and stylish. You can add humor or interactive sessions (互动环节) to your presentation to gain the audience attraction.

    Hello, Listeners. Welcome to Henton Hospital Radio. Before our music program at four, I'm going to repeat some of our hospital rules.

    The hospital can sleep 800 patients. There're 8 beds in each ward (病房). The visiting hours are in the afternoon from 2:30 to 3:30 and in the evening from 7:00 to 8:00. But remember only two people can see you at the same time. Sorry about that, but you can see what would happen if we didn't have these rules.

The other rules are about our hours. We start quite early—you might not be used to that. We wake you at 6 o'clock, and breakfast is at 8 o'clock, lunch is at noon.

    There's tea at 3:30 and supper is at 6 o'clock.

    You can see the non-smoking sign –-- we don't allow smoking in the wards. I'm sure you understand why. However, if you do need to smoke, there are some smoking rooms where it is allowed.

    You will find the radio switch (开关) on the wall near your bed, with your own headphones, if you want to listen. It's our own hospital radio wishing you a quick recovery (康复).

    Ask any group of teenagers in the UK what they most like to eat, and foods like pizzas, curries, pasta, burgers and chips are bound to get mentioned and many young people would probably also list hanging out at the local fast food restaurant as one of their favorite pastimes (消遣).

    But what teenagers like to eat is not necessarily what they should be eating. According to the National and Nutrition Survey, far too many young people in the UK between the ages of 14 and 18 consume too much fat sugar and salt in their diet and take in too many calories. Meanwhile their intake of starchy carbohydrates (含大淀粉的碳水化合物), fibre, iron, vitamins and calcium is too low.

    For a growing body, eating foods containing plenty of calcium, such as milk, yoghurt and cheese, is particularly important as calcium is essential for the development of healthy, strong bones. Similarly, foods that are rich in iron are good for young, rapidly developing bodies, so red meat. bread, green vegetables, dried fruit and tonified(使增强体质的) breakfast cereals are also recommended.

    It is during our teenage years that habits of lifestyle can become entrenched (根深蒂固的),so it is crucial (全关重要的)that young people are educated about what foods arc good for them. In 2005, in an attempt 10 change eating habits and open teenagers' minds to new flavours and new tastes, celebrity chef Jamie Oliver launched a "Feed Me Better" campaign. As part of a television series Jamel School drivers, he worked with teachers and cooks in a number of schools across the UK to provide more healthy, nutritious school meal opt ions. Although there was initial resistance from sonic teenagers and parents. the campaign was generally hailed (把...... 誉为)as a huge success and helped to influence governmental policy on nutritional standards for school meals.

    No one expects to end the teenage love affair with fast and junk food but. hopefully, if projects "Feed Me Better" and the government's own "Change for Life" campaign continue to give out the right messages, more young people will understand the importance of balancing occasional treats with healthier food options.
