Lots of people stress out about talking in front of the class or getting laughed at if they make a mistake in front of an audience. {#blank#}1{#/blank#} The “stress hormones" that your body produces at times like these can actually help you focus.

    But when worry and stress about performing get to be too much, these hormones give people that “red alert(紧急状态)” feeling—the one that causes you to feel cold or sweaty, or get butterflies in your stomach. {#blank#}2{#/blank#}

    Be prepared. {#blank#}3{#/blank#} Rehearse(排练) as much as you can and practice in front of others at every opportunity. Most of all, think positively. Tell yourself “I'll be OK" or “I can do this" even if you are not 100% sure of it

    Look after yourself. Before big performances it's easy to let taking care of yourself slip as you spend too much time on rehearsals and practice. {#blank#}4{#/blank#} Exercise can also help you feel good, and along with sleep and nutrition, is an excellent way of keeping those stress hormones from getting out of control.

    Find out what the experts do. You can find books, DVDs, and online information about how to give your best when you perform, depending on what type of performance you're preparing for {#blank#}5{#/blank#} Or ask the cast of your school play or your drama or music teacher how they beat stage fright. And if your parents or grandparents ever performed, they may have their own secrets to share.

    Robert is a boss who hires me as a helper.He has lost his house and now has to live back at home,with his mother,at 46.

    We had a job in Fort Bending.Robert bought me breakfast there.As we were leaving,a man walked to us asking if he could get some work from Roberts' company.Robert explained there was no work for the man and the man started to walk away.As I looked at the man leaving from Robert,I saw Robert taking out some money and went after the man to gave it to him.I asked Robert,"Why did you do that?"Robert said "He really had bad luck—what does a few dollars matter?"

    After a very long,hard day,we stopped at a Quick Trip for a soda.I got through the checkout ahead of Robert and went back out to the work truck.Beside the truck was a woman in a car.She had 3 kids and asked me if I could help—she had been evicted and had nowhere to go with her children.They were living in the car.I told her I was also hurting in these times,so I could not.Robert came out,opened the work truck and we got in.I told him about the lady.I didn't even finish the story when Robert was out his door around the truck and gave the women money to help them out.When Robert returned I asked,"Why did you do that,she didn't even ask you".He said,“I have an ex-wife（前妻）and a kid.If they need help and I am not able,someone will help them”.

    I grew up in New York my whole life. I studied in a perfect college that happened only to be an hour away from home. Then, about three weeks before the spring term was over, my parents told me we were moving to Arizona that summer. They asked me if I was going to transfer (转学) to another college. I said no. I was not going to change everything in my life at one time and I loved my college and all the amazing things I was doing there. It was my second home; I would not leave everything I knew at the same time since that was asking for trouble.

    I never imagined it would be this hard but, at the same time, the best thing that could have happened to me.

    When out in Arizona, life was hard. I didn't know anyone other than my family and friends. I couldn't bear the extreme heat. But it has helped me so much. I have started working on my writing. I also have time to work out in the gym. It has helped me realize that no matter where you are or who you know you can always find something that you enjoy.

    When back at school in New York, it was hard as well. Living close to home was my security blanket. If something was wrong I could get in my car and drive home and see my family. After my family moved to another city, I lacked security and was always controlled by anxiety. However, it helped me learn independence and forced me to be brave.

    I' m so thankful that I didn't transfer to a different school, which has given me the opportunity to go back and see best friends in my hometown. A year ago, I officially left my hometown for good. It has helped me grow and I am so thankful that I have had this experience. Now, when I graduate from college, I can go anywhere I want. I am no longer afraid to go out on my own into the world. The world is full of opportunities and pleasure and I can't wait to see where I will be next.

    A name is more than just a word. It carries the weight of a person's whole identity. A name can represent a person's ethnicity (种族身份) and culture, or show respect for their ancestral roots. A self-given name may represent a person's beliefs or chosen identity.

    Everyone has the right to have their name pronounced correctly. It is a sign of respect for a person's individuality. "A person's name is to him or her the sweetest and most important sound in any language," Dale Carnegie writes in his book How to Win Friends and Influence People. Behind each name is a story, and when a name is anglicized (英语化), mispronounced, or ignored, that story is dismissed.

    A name mispronounced for a long time can negatively impact a person's attitude toward their own identity. It can create feelings of shame or embarrassment because they are made to feel like a burden. In the long term, this might cause someone to distance themselves from their roots. They may begin shying away from their native language, culture, and family for the sake of fitting in.

    In order to avoid this, many international students living in the U.S. choose English names. People shouldn't have to ignore their identities for the sake of someone else's convenience.

    Everyone makes mistakes, and not everyone can get a name right on the first try. Mispronouncing a name repeatedly, however, shows a lack of effort. It is not okay to be comfortable with mispronouncing names, and being unfamiliar with a language is no excuse.

    If you're unsure whether you're pronouncing a name correctly, just ask. Think of it as a way to expand and strengthen understanding, both personally and culturally. When meeting someone for the first time, make sure that you heard the name correctly. It doesn't take a lot to simply repeat the name back. Spell it out. Write it down. Do whatever you have to do to get the name right. Making the effort to correctly pronounce someone's name is an essential part of cultural competency (文化素养). Without this, we cannot expect to show respect and tolerance for our diverse community.

    Almost every second of every day an older adult falls in the United States. That's approximately 29 million falls per year and nearly 27, 000 deaths, according to the Centers for Disease Control and Prevention.

    Still in the stating stage, the Active Pelvis Orthosis (APO) system in Switzerland wants to make a lightweight, wearable exoskeleton (外骨骼) that could detect signs of balance loss and assist with balance recovery to keep the elderly wearer from falling, only when needed.

    Other exoskeletons, either in development or on the market today, assist with movement and make heavy objects feel lighter. Mobility-impaired people can walk again. But none of these devices predict what the wearer is going to do next and take measures to correct an unsteady move.

    The 3 kilogram (6.7 pound) exoskeleton was built entirely from scratch by the research team and is designed to be worn on the lower half of the body. A waistband connects to two movable carbon fiber braces (支架), each one positioned on the outer side of a leg. Tiny motors and so-called "adaptive oscillators" (适配振荡器) in the computer circuits use a special process to detect the, wearer's unique paces. That part takes just a few minutes.

    While wearing the exoskeleton, a person may feel the braces and the motors pushing slightly on their legs. If their paces go against normal, the motors create a force in the braces that cause them to stiffen up and push a little more strongly against the legs, which provides stability.

    In the next three years, the APO hopes to develop something that is commercially available.

    The weather affects many aspects of people's daily life. Knowing and understanding what the weather is doing is useful.

    However, the weather is also one of the most unpredictable elements in the world. Although many people watch the morning news and gather the information about the weather, this is often wrong. Whole days can be ruined by believing that the weather will be one thing, when it turns out to be another. However, owning wireless weather stations allows the owners to monitor the weather for themselves.

    Not only will these weather stations allow the owners to see what the weather is doing, but it is personalized(个性化)to them and their area. Wireless weather, stations are specifically prepared for the immediate neighborhood. Plans will be able to be made, and important decisions will no longer be ruined by bad weather.

    Although these weather stations are typically seen in homes, they can also be used very easily on farms and fishing boats. Both farmers and fishermen rely on the weather for their business and using up-to-date weather information is quite indispensable. By using the wireless weather stations, it can determine for them when to harvest crops and head back to the shore. Because of the size of the weather station, they can be moved very easily and used wherever necessary for people.

    The wireless weather stations are great for all homes, especially for areas that suffer from extreme weather conditions. The up-to-date, instant weather reports will allow a person to monitor what the weather is doing and if the bad weather is heading in their direction. Extreme weather tends to come very quickly; therefore, any information that is received is helpful.

    The weather stations are very simple to set up and are run by solar panels(太阳能板), ensuring they will work even if there is a power-cut. They are far smaller than those in previous years and give a couple of very simple read-outs for the owner. They are easy to use and fascinating to understand.
