How to express yourself to others
Every person on the planet communicates in some fashion. And one of the hardest things to do when you're communicating with someone is expressing yourself. After all, words have the power to give life and death... especially in relationships. 1.
If you have a fear of people, people will avoid you. It's a vicious cycle（恶性循环）. You avoid people because you fear that they will hurt you. People see your coldness, and either think the worst （that you are stuck-up（傲慢的）），or satisfy your desire and leave you alone. 2. You'll have a hard time getting close to them when you bottle everything up inside. Your relationships will all be shallow.
Your inability to express yourself will haunt（萦绕于）you in time of trouble. You'll need help, and you'll want help, but you won't seek it. You'll hide. So, no one helps you. Then you grow bitter and angry. What's more, it can cause isolation. You build walls around your emotions and people consequently leave you alone. Gradually, your life will be empty. Life is relationships. 3.
However, reading will help you learn how other people express themselves. Pay attention to word usage, diction（措词）,flow, voice and tones. These will give you ideas of expressing yourself. 4. They'll provide you with many ways of expressing your emotions and help you express yourself better.
Besides, you can do some writing on your own. Start a novel. Write letters. Keep a journal or diary. You'll find that writing helps you to sort through your thoughts. Writing gives you focus and direction.
5. You can't catch it from someone who has it. It is the spiritual state of mind that is the direct result of fear. There is really only one type of fear and that is the fear of the unknown. Don't fear what other people think about you. Honestly, your imagination will create far worse imagination than what most people will ever think.
A.Social anxiety is not a disease.
B.That will make them feel needed.
C.So it is important that you learn to express yourself.
D.All of these factors have some relationship to happiness.
E.Look up words that you've never seen before and use them.
F.The stronger your relationships are, the more joy you'll have in life.
G.When you can't open up to people, they will feel that you are unapproachable.
What consumers expect when they see a food makes the palate（额）taste certain flavors. The strong associations between color and flavor are well established in the scientific community. Research on the subject dates back to the 1970s. For example, consumers expect yellow foods to be sour and black foods to be bitter.
Branding, packaging and color quality of the product itself play a big part in creating and maintaining expectations. Food brands have long understood this and worked to establish standards. Federal regulations grade the color of orange juice. Businesses provide color- matching services for companies to select the right color for a particular product. In some cases, color can overpower other senses and convince people they taste flavors that aren't there.
The Penn State researchers set out to confirm long-standing research into the relationship between color and taste. And they found what consumers see when they eat matters as much as—if not more than—what they taste, and the links could be more flexible than many thought in some cases.
"This might have potential impacts in the food industry if a company were to launch a new flavoured product with a color. Some consumers might not learn or accept a new color and flavor pairing（配对）as well as others Penn State Food Science doctoral candidate Molly J. Higgins said in a written statement.
Although it may be possible to completely change food colors, it may not be advisable. According to this study, 40% of consumers would be left behind, stuck on familiar patterns. That's a big risk for food brands to take. Consumers tend to want to know what they're in for when they select a product—and color is a big part of that. While it's interesting that consumer expectations of colors could change, the risk of unexpected colors is high for any company.
Many food brands rely on visual expectations to pull customers into unfamiliar products. A hamburger that copies the appearance and color of a beef patty （小馅饼）will cause a different reaction than a green-colored veggie（素食者）--dense alternative. But while today's consumers have expectations of flavors of items with different colors, they also have expectations that natural materials are used. While these materials are often preferable, they present a challenge. General Mills changed artificial dyes （染料）to natural ones in Trix cereal. Consumer anger followed. Many found the earthier tones depressing, despite no change in flavor. Chemicals and all, they wanted the original back. The company eventually switched back, choosing to treat color as being more important than other things.

C.To stress the importance of color in food selection.
D.To stress the difference between color and taste.
4.What can be the theme of the text?

B.How deep are color-taste associations?
C.What factors affect the flavors of food?
