Summer is the season to dive into new activities and relax. And right now is the time to make sure that you're ready for the great outdoors, the holiday planning and travel, and the bathing suit beach days.

    If you want to lose weight before summer, concentrate on dropping no more than a pound or two a week.{#blank#}1{#/blank#} And when you trouble yourself, sooner or later you，re going to gain it back. Operate on a 500-calorie-a-day deficit (亏损).{#blank#}2{#/blank#} So if you cut 500 calories a day for seven days straight, you'll lose a pound a week right there.

    Operating at a decrease of 500 calories a day should involve both eating less and moving more. For example, you could consume 300 fewer calories and bum 200 extra per day.

    Include both healthy eating and exercise in your weight-loss plan, and break the 500-calorie goal into small groups to make it more reachable.{#blank#}3{#/blank#}

    To cut 100 calories:{#blank#}4{#/blank#} Have vegetable pizza instead of pepperoni (意大利辣香肠). Use our Nutritional Needs Calculator to determine how many daily calories you should consume in order to lose, gain, or maintain your healthy goal weight. Once you've reached your goal, recalculate your nutritional needs for keeping extra weight off all summer long.

    To burn 100 calories: spend 15 minutes biking. {#blank#}5{#/blank#} Spend 20 minutes gardening. Keep on exercising at least 30 minutes daily a week. Reading food labels and counting calories or writing down what and when you eat can give you more control as well.

A. Here are some simple ways to get there.

B. Walk or run one mile.

C. A pound is 3,500 calories.

D. It is okay to have some snacks between your meals.

E. You should always make sure you get a lot of sleep.

F. Anything more than that usually means you're troubling yourself.

G. Eat a chicken breast without the skin.

    Worldwide, the most people willing to return your mobile phone if you've lost it are to be found in Slovenia, and the fewest in Malaysia. This finding is the result of an interesting study in 32 of the world's largest cities. Altogether, researchers 'lost' 960 new mobile phones. They got back 654 of them，or 68 percent. Prague came in at number eight. There, 23 out of 30 people who were willing to return the mobile phone.

    It wasn't a traditional study. Two researchers carefully chose different places such as areas with high crime(犯罪)and busy downtown shopping areas, to “lose” the phones. When one of the researchers dropped a phone, the other would keep watching from a distance. The honest finders tried their best to find the owner with the help of the address book in the phone. They were told why the study was done and asked why they acted the way they did.

    It was found that the busier the place where the researchers dropped the phone, the greater the chance of it being returned. Another interesting finding was that women were generally more likely than men to return the phone. Researchers also found that most people still have a sense of honesty. “Crime is simply not good behavior (行为), ”said an expert. “People want to trust others, and want to be trusted.”

    The people who built Stonehenge in southern England thousands of years ago had wild parties, eating barbecued pigs and breaking pottery. This is according to recent work by archaeologists — history experts who investigate (调查) how human beings lived in the past.

    Archaeologists digging near Stonehenge last year discovered the remains of a large prehistoric village where they think the builders of the mysterious stone circle used to live.

    The village is about 4,600 years old, the same age as Stonehenge and as old as the pyramids in Egypt. It is less than two miles from the famous ancient landmark and lies inside a massive man­made circular dirt wall, or "henge", known as the Durrington Walls.

    Remains found at the site included jewellery, stone arrowheads, tools made of deer antlers, wooden spears and huge amounts of animal bones and broken pottery. "These finds suggest Stone Age people went to the village at special times of the year to feast and party", says Mike Parker Pearson from Sheffield University in England.

    He said many of the pig bones they found had been thrown away half-­eaten. He also said the partygoers appeared to have shot some of the farm pigs with arrows, possibly as a kind of sport before barbecuing them.

    An ancient road which led from the village to the River Avon was also found. Here, the experts think, people came after their parties to throw dead relatives in the water so the bodies would be washed downstream to Stonehenge.

    Parker Pearson believes Stonehenge was like a cemetery where ancient Britons buried the dead and remembered their ancestors. "The theory is that Stonehenge is a kind of spirit home to the ancestors."

    The recent discovery of the village within the Durrington Walls shows that Stonehenge didn't stand alone but was part of a much bigger religious site, according to Parker Pearson.

    People still come to worship and celebrate at Stonehenge today. They meet there when the sun sets on the shortest day of winter and when it rises on the longest day of summer. But the days of barbecuing whole pigs there and throwing family members into the river are a thing of the past.

    It's nice being nice to others; it's also great to give people a hand. However, if you start to hurt yourself by doing so, then this is not so healthy.{#blank#}1{#/blank#}If you fear that you might fall into this category, the following tips will help you to stand up for yourself and regain your self-confidence.

{#blank#}2{#/blank#}

    Although you may often stay silent if something is wrong or bothers you, it is better to speak your mind right away. You don't have to be rude, but you do have to be firm and direct. Don't do things for others if you don't really want to. Speak up, and soon others will be seeing you in a whole new light.

    Start small.

    {#blank#}3{#/blank#}This will allow you to practice being brave and self-confident. Tell a person who has cut in line in front of you to move to the back of the line, or tell a salesperson to do that. Before long, you will be confident enough to stand up to your friends and family members.

    Judge well.

    When dealing with others, you have to exercise good judgment. {#blank#}4{#/blank#}If a colleague isn't doing his part, you should rightfully demand that he start doing so. However, if a taxi cuts you off in traffic, just let it go.

    {#blank#}5{#/blank#}Rome wasn't built in a day. If you want to get back again after having been a pushover(耳软心活的人), it's best to take one step at a time.

A. Express yourself.

B. Regain your confidence.

C. Start by speaking up for yourself with strangers.

D. Everyone has the right to live without being judged.

E. If you slip back into the pushover mode every once in a while, don't blame yourself.

F. Sadly, some people are so easily pushed around that they come to be seen as pushovers.

G. It's one thing to be confident, but quite another to forcefully say no to an unreasonable request.

    When you need a job very much, you may end up taking one for which you are over qualified. Although you were initially grateful just to have the work, you now feel bored and depressed. Is there any way to change that?

    Start by changing your opinion, says Caitlin Kelly, the author of Malled, a book based on her experience as a sales clerk after losing her job in journalism. "Don't focus on what you're not getting but what you are getting," she says. "Be patient and work attentively with a wide range of people. It doesn't matter what the job is –there are always things you can learn and skills you can develop."

    Hilary Pearl, the founder of a coaching firm, says, "Tell yourself the current situation isn't the end of your career. Don't overdramatize(过分夸大)the negative aspects but try to view the situation more philosophically: life has a series of stages, and this is one of them. Don't forget to study even in the worst stage."

    Consider that because you're overqualified, you may be able to learn or do things on the job that might not have been possible in a more demanding position, says Sarah Hathorn, the chief executive of Illustra Consulting. "You could spend your extra time in learning different aspects of the business and teaching others in the organization," she says.

    Is it possible to make your work more challenging, even if your job responsibilities aren't likely to change?

    Of course, you may seek tasks and responsibilities that force you to learn something new or to work harder. "You may be operating on autopilot(习惯性地)right now, but chances are that people above you are stressed," Sarah Hathorn says." Take things off your boss's plate and let him know which projects or tasks you want to learn more about."

    Always express your request positively, saying that you love new challenges, rather than complaining that you're bored and underused, says Ethun, the president of the Park Avenue Group. In your down time, educate yourself about the company and its industry. "Read corporate information, analyst reports and related news articles," she says. "If your boss accepts your suggestions, it will make you a more valuable employee."

The ancient Egyptians thought so little of the brain that when a king died, they removed the brain from his body and threw it away. The Egyptians assumed, like many people before and after them, that consciousness — your mind and your thoughts existed in the heart.

Now we know that the mind is a product of the brain, but how exactly does this 1.5-kilo piece of matter create a mind that allows you to think about yourself, experience happiness and anger, or remember events that happened 20 minutes or 20 years ago? This isn't a new question. Today, however, powerful new techniques for visualizing the sources of thought, emotion, behavior, and memory are transforming the way we understand the brain and the mind it creates.

Have you ever stopped and thought, "What's wrong with me today? I just don't feel like myself"? Perhaps you were more tired or worried than usual — but somehow, you knew that something was different about you. This self-awareness - the ability to think about yourself and how you're feeling-is an important part of being human.

This part of of your mind has its origins in the prefrontal cortex — a region of your brain just behind your forehead that extends to about your ears. Before this area began to function (around age two), you didn't understand that you were a separate individual with your own identity. As this part of your brain developed, you became more aware of yourself and your thoughts and feelings.

Though humans may share certain emotions and recognize them in others, we don't all have the same emotional response to every situation. In fact, most emotional responses are learned and stored in our memories. The smell of freshly cut grass, for example, will generate happy feelings in someone who spent enjoyable childhood summers in the countryside, but not in someone who was forced to work long hours on a farm. Once an emotional association like this is made, it is very difficult to reverse it. "Emotion is the least flexible part of the brain," says psychologist Paul Ekman. But we can learn to control our emotions by becoming consciously aware of their underlying causes and by not reacting automatically to things in our environment.

For centuries, people have studied the brain, but it is only in recent years that we have really started to learn how it works. Nevertheless, there is still a long way to go before we understand our mind's many complexities.
