Body language is an important part of communication(交流). If you want to communicate well, it's important to understand how you can (and can't) use your body to say what you mean, especially when you're in a foreign country. If a person is bored, he won't look at the person who is talking to him. He will find other things to do. He may also keep looking at his watch or a clock. If a person is open to you, his arms and legs will not be crossed. And if a person is relaxed, you will know it by looking at his body, even his breathing is slower.

Here are some examples of body language:

    Eyesight plays a very important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight:

    Schedule yearly exams.{#blank#}1{#/blank#} Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.

    Protect against UV rays (紫外线). Long-term stay in the sun creates risk to your eyes. No matter what the season is, it's extremely important to wear sunglasses.{#blank#}2{#/blank#}

    Give your eyes a break. Two-thirds of Americans spend up to seven hours a day using computers or other digital products.{#blank#}3{#/blank#}Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.{#blank#}4{#/blank#}As part of a healthy diet, eat more fruits and vegetables each day. Vitamins (维生素) C and E help protect eyesight and promote eye health.

    Practice safe wear and care of contact lenses (隐形眼镜). Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk.{#blank#}5{#/blank#}Otherwise, you may have problems such as red eyes, pain in the eyes, or a more serious condition.

A. Eat your greens.

B. Eye care should begin early in life.

C. They can properly protect your eyes.

D. Stay in good shape by taking more vitamins.

E. Parents usually don't care about their own eyesight.

F. Always follow the doctor's advice for appropriate wear.

G. This frequent eye activity increases the risk for eye tiredness.

    Cheating is nothing new. But it's becoming a lot more sophisticated. Republican vice-presidential candidate Sarah Palin was caught out once. A photo taken after the speech she'd given on a "return to conservative principles" showed her left hand covered with crib notes. These included the words "energy, budget cuts, tax" and "lift Americans' spirits". The word "budget" had been crossed out. Video footage also showed her reading from her hand when asked what top three things a conservative-led congress should do. Writing notes on your hand is one way to cheat in an exam. But these days, it's a lot easier ... especially with the Internet.

    Anyone who wants to cheat in an exam can probably find the answers online. There are hundreds of sites offering solutions to all sorts of tests. And it's a lucrative business. One operator in Oregon made $700,000 in about nine months before his arrest. The owner of a website in Ohio pocketed more than $300,000. And a famous overseas site is estimated to sell about 146,000 sets of answers and take in about $10 million per year. Actually, getting hold of the exam answers isn't that hard. Some do the exam themselves and use button cameras or document-scanning pens to copy the tests. Others organize for a group to take tests repeatedly until they can memorize the entire exam between them. Others simply bribe exam administrators.

    At the moment, such business is booming. More and more companies now require their employees to take professional exams. And hundreds of businesses and trade organizations have introduced formal certification programs to measure employee skills. In the US alone, at least 2 million exams are taken every year for information technology certification. But employees also have to take exams for all sorts of professions from crane operators to court reporters to school bus drivers and financial planners. Test officials estimate that hundreds of thousands of test-takers have used the Internet to buy answers for professional tests. And a recent survey found that 28 percent of test centres had at least one cheating incident over the last five years. In one incident, tens of thousands of soldiers obtained answers to tests in a range of military skills.

    Many see this as a cause for concern. Many tests are for work in sensitive areas such as defence installations and hospitals. Now, how would you feel if you knew that the people in charge of the computers controlling nuclear weapons might have cheated in their tests, and may not really know what they're doing?

    On my first day of high school, I asked an eleventh grader where my class was. And he told me it was "on the fourth floor, next to the pool." I found out five minutes later that we don't even have a fourth floor and there's no pool either! Besides that, I didn't have any trouble with the older kid.

    I think the biggest difference between middle and high school is the homework load (工作量) and size of the school. I went from maybe fifteen minutes of homework a night to several hours, so I had to learn how to make full use of time! Our class size is around 550, but joining in clubs, sports, music, and other activities at school makes it easier to get to know people in every grade.

    The best advice I can give about the years you spend in high school is to learn things for yourself, not just to get a good grade. There have been so many tests that I've prepared for the night before, gotten an A, and not remembered anything later. I've changed that this year, and I enjoy school so much more. Don't take easy classes just to have a simple year. If you have a choice between chemistry and sports, the first will prove to be a lot more useful!

    While drinking and smoking might be present in some middle schools, they're also around in high school. I have a lot of friends who promised they'd never drink or smoke, but are now partying every weekend. If you have "fun" and spend your nights wasted instead of studying, you will regret it when you're applying for (申请) college. The "friends" who say you're a loser for not partying are really not your friends at all. It's hard to see your closest friends grow apart and go in different directions, but don't follow their footsteps. Create your own path in life and make your own decisions.

    Do you enjoy your work? Maybe you do or maybe you don't. Chances are that you fall somewhere in the middle: you have good days and bad days, and you could definitely be happier than you currently are.{#blank#}1{#/blank#}.

    Be Friendly to Your Colleagues

    In some big offices, people might not even say "good morning" to one another. {#blank#}2{#/blank#}. You might think that you have nothing in common with them, but if you strike up a conversation, you may well find that they share some of your interests, hopes or ambitions.

    Focus on How You're Helping Clients

    Some jobs are pretty tiresome — there's no way round that. Whatever you're doing, though, you're helping someone.

    Perhaps you work in McDonalds, helping customers who want a cheap, quick meal. Perhaps you do data entry, helping a big company to get their records organized so that they can take better care of their clients. In most jobs, you've got the potential to make someone else's day that bit better.{#blank#}3{#/blank#}.

    Do Your Hardest Task First

    Have you ever put off a difficult phone call or a high­pressure task for days and days, only to find it appears larger and larger in your mind? I've read a lot of productivity advice over the past few years, and something that almost all experts seem to agree on is that it's a good idea to get tough tasks out of the way as quickly as possible.{#blank#}4{#/blank#}. Plus, you'll constantly have that task hanging over you and dragging your mood down.

    {#blank#}5{#/blank#}

    Try eating at regular intervals — and go for healthy, tasty foods which make you feel energized rather than sluggish. Fresh fruit is a great snack option, or you can have dried fruit, nuts and/or seeds. Don't forget to drink enough water, too.

    These are all little, but significant, ways to be happier at work today. Put them into practice and you will feel inspired!
