    You've probably heard the term “you are what you eat.” If you decide to eat sugary foods that are heavy with fats then expect to feel lazy and have no energy. But if you decide to eat fruits, vegetables and make other healthy eating decisions you'll find that you're full of energy.

    Never stop learning

    Challenge yourself constantly---whether it is puzzles, reading, cooking or other tasks that will keep your mind working. If your mind is always learning new things and active, you'll realize that it's much easier for you to learn new things and to function. {#blank#}2{#/blank#}

    Stay fit

    Being in good health and staying in shape is a big part of staying sharp. {#blank#}3{#/blank#} If you choose to be lazy then your body is not going to give you the energy that requires remembering things and completing tasks. However, if you put forth the effort into being health then your body will expel(释放)the energy you need to achieve your goals.

    Ensure enough sleep

    Be sure to get the necessary amount of sleep that your body needs to function on a daily basis. {#blank#}4{#/blank#} It also helps your body build up an energy reserve so you can improve your ability to focus and avoid distractions.

    Socialize more

     {#blank#}5{#/blank#} Social interaction will help you develop multitasking, problem solving and other skills that are necessary in life to keep your mind sharp.

    Next time a customer comes to your office, offer him a cup of coffee. And when you're doing your holiday shopping online, make sure you're holding a large glass of iced tea. The physical sensation (感觉) of warmth encourages emotional (情感的) warmth, while a cold drink in hand prevents you from making unwise decisions—those are the practical lesson being drawn from recent research by psychologist (心理学家) John A. Bargh.

    Psychologists have known that one person's perception (感知) of another's “warmth” is a powerful determiner in social relationships. Judging someone to be either “warm” or “cold” is a primary consideration, even trumping evidence that a “cold” person may be more capable (能干的). Much of this is rooted in very early childhood experiences, Bargh argues, when babies' sense of the world around them is shaped by physical sensations, particularly warmth and coldness.

    Feelings of “warmth” and “coldness” in social judgments appear to be universal. Although no worldwide study has been done, Bargh says that describing people as “warm” or “cold” is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries.

    To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students. A research assistant who was unaware of the study's hypotheses (假设), handed the students either a hot cup of coffee, or a cold drink, to hold while the researcher filled out a short information form: The drink was then handed back. After that, the students were asked to rate the personality of “Person A” based on a particular description. Those who had briefly held the warm drink regarded Person A as warmer than those who had held the iced drink.

    “We are grounded in our physical experiences even when we think abstractly (抽象的),” says Bargh.

    On the third Sunday in June, Americans take time to recognize and thank a special person in the family -fathers! Father's Day celebrates the importance of fathers, young and old and the men thought of as father figures.

    The words "the child is father of the man" come from William Wordsworth's poem My Heart Leaps Up. "It means people's personalities form when they are children. They will most likely have the same qualities as an adult that they had as a child.

    Used in everyday speech, one could say, "In his case, the child was father of the man; he loved nature as a child and now works as a botanist(植物学家)".

    Let's say you want to tell a child a story about something that happened long before they were born. You could say it happened when they “were just a twinkle in their father's eyes.” This expression has a humorous and dreamy feel. Here, the word “twinkle” suggests the interest your father had in your mother.

    When a much older man is interested in a much younger woman and supports her with his money, he is called he “sugar daddy.” The money part is very important-that's the sugar.

    Sometimes fathers are not a good influence or active in the lives of the children. In that case, a person may look for a father figure, a man who is not actually the person's father but who acts like one.

    The relationship between a man and his son can be complex. But the relationship between a father and daughter is often simpler. The expression “daddy's little girl” is understood to mean that, in a father's eyes, his daughter can do no wrong.

    There is usually not a dry eye at any wedding during the traditional father-and-daughter dance, especially if they are dancing to a song like Michael Buble's “Daddy's Little Girl.”

    If doctors want to test you for something, they'll usually take a blood or urine sample. But wouldn't it be much more convenient if they just asked you to breathe through a special instrument?

    In fact, your breath can say a lot about you. In traditional Chinese medicine, doctors draw a conclusion about the health state of a patient based on the smell of his or her breath; trained dogs and rats can identify the smells of the breaths of people suffering from certain cancers; traffic police also monitor drivers' alcohol consumption by testing their breaths.

    Just like blood and urine, your breath contains lots of “metabolites” —the waste chemicals that the body produces, which vary from person to person. They are like personal health fingerprints, which is why scientists sometimes call them “breathprints”, according to Science Daily.

    Compared to blood or urine testing, breath testing takes only seconds instead of hours, and it requires neither a needle nor a container to hold the body fluids(液). This means the test can be taken frequently to better detect early signs of diseases and monitor the progress of a medical treatment.

    On the other hand, as an identifier, you might think that breaths are not as reliable as fingerprints since they might change based on what you eat. However, researchers in Zurich, Switzerland mapped 11 healthy volunteers' chemical patterns by having them breathe through a special instrument, and they found that each pattern was unique and the patterns didn't change much throughout the day, reported BBC.

    “Our goal is to develop breath analysis to the point where it becomes competitive with the established analysis of blood and urine,” said Malcolm Kohler, professor at the University Hospital Zurich.

    American and British people use different greetings. In the USA the commonest greeting is “Hi”. In Britain it is “Hello!” or “How are you?”. “Hi!” is creeping(不知不觉地进入) into British, too. When they are introduced to someone, the Americans say, “Glad to know you.” The British say, “How do you do?” or “Pleased to meet you.” When Americans say “Good-bye”, they nearly always add, “Have a good day.” or “Have a good trip.” etc. to friends and strangers alike. Britains are already beginning to use “Have a good day.”

    The British usually use “got” in the sense of “have”. The Americans hardly ever do.

AmE: Do you have a car, room, etc.? Yes, I do.

BrE: Have you got a car, room, etc.? Yes, I have.

    There are a number of differences between American and British English in the spelling of words, e.g. check(US)/cheque (UK). Many American words ending in “or”, e.g. honor, labor are spelt in British English with an “our,” e.g. honour, labour. Many verbs in American English with “ize” or “izing” forms, e.g. organize, realizing are spelt in BrE with “ise” or “ising”, e.g. organise, realising. In American English, “practice” is used both for the verb and noun. In BrE, the verb is spelt “practise”, and the noun “practice.” In American English, one writes “traveler,” while in British English, one writes  “traveller”.

    It was once predicted that British and American English would become separate languages finally. But the opposite has happened. The links(联系) between the two countries are so strong that linguistically(语言上地),and probably culturally(文化上地) too, they are closer together than ever.

    Let's face it. No one drinks diet sodas for the taste. People drink diet sodas in the hope that it will help them lose weight or at least keep them from gaining it. Yet it seems to have exactly the opposite effect, according to a new study.

    Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didn't drink diet sodas. "What we saw was that the more diet sodas a person drank, the more weight they were likely to gain," said Sharon Fowler.

    The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly 10 years.

    While the findings are surprising, they also offer some explanations.

    Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet sodas, they don't lose weight at all. "We weren't seeing weight loss necessarily, and that was confusing to us," said Rogers.

    So why would diet soda cause weight gain? No one knows for sure yet, but it could be that people think they can eat more if they drink diet sodas, and so over-compensate(补偿) for the missing calories.

    A related study found some sweeteners (甜味剂) raised blood sugar levels in some mice. "Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky," said Helen P. Hazuda, professor at the University of Texas's school of medicine. "They may be free of calories, but not of consequences."
