article: Emeralds come in a range of colors. Color is one of the most important factors in determining the value of an emerald. The variance of color in emeralds is due to differing amounts of chromium, vanadium, and iron in the environment in which the stones formed. Color can be subdivided into the categories of hue, tone, and saturation. Hue is probably what you think of when you hear the word "color." An emerald's hue is its specific type of green. Emerald hues can range from bluish-green to a more yellow-green. For example, Zambian emeralds are characterized by deep bluish greens, while Brazilian and Colombian emeralds often take on a rich, pure green hue. Tone refers to how light or dark the color of an emerald is. Emeralds can range from very light green to very dark green in tone. The association of tone and value is somewhat complicated. Darker emeralds are often considered more valuable, but if an emerald becomes too dark, it becomes less valuable. Emeralds with medium to medium-dark tones are the most valuable emeralds in the market. Emeralds with pure green or blue-green tones are the most desirable, in part because blue-green emeralds are associated with a very famous and highly-regarded gem mine in Columbia called the Muzo Mine. Be aware that emeralds that are too yellow or too blue may not be considered real emeralds and are therefore far less valuable. Saturation is tied to the gem's transparency. Emeralds with high saturation (which means that they are highly transparent) are more valuable than emeralds with low saturation. Saturation can be tied to both inclusion and tone; very included gems can appear less transparent. Similarly, very dark green emeralds do not absorb much light, so they appear duller than lighter emeralds.

Write an article based on this "Plan appropriately. Write down an outline for your speech. Practice your speech and record it. Breathe deeply, smile, and stay hydrated. Rest well and dress for success."
article: Spend time putting your speech together so that when you give it, it flows naturally and feels normal to you. Being familiar with the content will greatly reduce stress. Visualize giving your speech, from driving to the location, getting on stage, delivering the speech, and returning home. This can help alleviate your anxiety and alert you of anything you still need to prepare. View your public speaking like a play. If you don't learn your lines you won't be able to act and engage your audience. When an actor doesn't know her lines, the audience is always aware. The more you prepare the less you have to worry about when speaking publicly. If it helps you prepare, create a character. You don't have to be just you. Take on a stage persona. If you're introverted, create a character who is extroverted and play that character when speaking. Plan everything that you can so that when it's time to speak all you have to do is focus on your speech. Not only should you know your speech inside and out, you should plan everything from what you'll eat to what you'll wear. Plan your outfit a day ahead. When it's time to get ready, you don't have to worry. Plan what and when you'll eat. If you know you get nervous and not hungry before speaking, then plan to eat a few hours earlier. You don't have to write out your whole speech. But you should have some sort of outline that works for you. While your speech should be pretty much memorized, having an outline will let you reference something to make sure that you're hitting all the points you need to. An outline will help you develop a natural flow to your speech. You won't have to panic if you forget what your next point was because you can look at your outline. You should also include the thesis, or main point, of your speech. Like in an essay paper, having a clear thesis that you will back up is a great help. Your thesis will inform you and your audience of what you will talk about. It will also show the audience that you are prepared and knowledgeable. You may get sidetracked during a speech depending on the forum you're in. Having an outline and really knowing your material will allow you to easily transition and get back on track. Rehearsing your speech and taking notes on how you speak, the tenor of your voice, body language, and other factors will allow you to speak with confidence. Then watch yourself and take notes on how you sound and look. Make necessary adjustments. Just like for any athlete or artist, practice is a key component to success. When practicing your speech, go a little slow to really digest what you are saying and how you are coming across. When you give your actual speech in public you'll probably have the tendency to speak faster than normal. But practice can help you keep a good tempo. Practicing will also help you memorize and feel prepared. When it's time to speak publicly, you'll know that you could do your speech in your sleep. Practice while you're doing other things, such as the dishes, mowing the lawn, or getting ready. Be sure to practice the middle of your speech multiple times, as this is the part that is most often forgotten. Don't just practice your speech from the beginning; start from the middle and rehearse it through the end a few times to help you lock each part in your memory. Breathing is a key component in delivering a great speech. Your breath and the oxygen you allow to enter your body will keep you calm and focused. Smiling makes you happy and water keeps you energized. When you smile, you feel better. When you allow yourself to take a moment to breathe you can slow your heart rate and process what you are doing and saying. When we get nervous we often take shorter more shallow breaths. This kind of breathing doesn't allow us to get as much oxygen and can cloud our thoughts. Long, steady breaths will help you keep a clear head and a calm body. Additionally, smile. Smiling triggers endorphins in our brains which make us happy. Make sure to stay hydrated as well. When you're dehydrated you can't think as clearly and can become tired much more easily. If you know that you're speaking in the morning, plan to get a full night's rest. Then, once you wake up feeling refreshed and energized, put on your outfit which you already planned to wear. Do whatever you need to do that relaxes you and allows you to get a good night's sleep. Exercise, watch a movie, read. Try to get eight hours of sleep so you wake up feeling refreshed. Plan your outfit beforehand so all you have to do is put it on. You should wear something that gives you confidence and makes you feel amazing. Whether it's that great suit that makes you feel like you can take on the world or that classy dress that fits your body perfectly and gives you confidence. Dress well and appropriately, but wear something that you feel great in. When you feel great about how you look, your confidence will soar.

Write an article based on this "Dig out your car. Check the tailpipe before you start the engine. Put down something gritty around the tires. Place solid materials in front and behind the tires to gain traction."
article:
Use a shovel or similar tool to clear away snow that surrounds the car. Try to make it so you can see all the tires. If there is ice be aware of it. In very heavy and/or deep snow, you may have to prioritize your efforts. Be sure to dig out tires and enough so you can get in the car. You may not have to remove ice that is textured. Ice that is rough will add traction, so usually not worth removing. After you've dug out your car, make sure that the tailpipe is free of snow. While you may have removed the snow from around it, make sure the tailpipe itself is clear and doesn't get buried again. This is important, as the exhaust could build up in the car if the tailpipe isn't clear. Pour a gritty substance in front, behind, and on the sides of your tires. Gritty substances will help your tires gain traction when you try to back up or move forward. Some substances you can pour include: Salt, which will not only help tires gain traction, but will melt the ice and snow underneath them. Kitty litter. Car mats, welcome mats, or carpet squares. Sand. If gritty materials don't work, look for other materials that could help your tires gain traction. This includes pieces of plywood, ridged sheet metal, or similar items. Then, place the items in front of or behind your tires so you can back or drive onto them and then out of the snow. If you have snow chains, you should put them on.
