The weather is getting hotter and you'll be getting thirstier playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you pour down your throat. Something that looks cool may not be good for your health.

    There are plenty of so-called energy drinks on the market. Most of them have an attractive colour and cool name. Their nutrition list also contains various things from vitamins to ginseng. Sounds great!

    But after a careful check you may find that most energy drinks contain high levels of caffeine. These drinks are typically aimed at young people, students, busy people and sports players.

    Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.

    Caffeine raises your heartbeat. Because of this, the International Olympic Committee has limited their use. The amount of caffeine in most energy drinks is at least as high as in a strong cup of coffee or strong tea.

    Research by Australian scientists has found that many teenagers are affected by caffeine. The results of their survey show that 27 percent of boys aged 8-12 take in more caffeine than their parents.

    There are potential health risks linked to energy drinks. Just one can of energy drink can make you nervous, have difficulty sleeping and can even cause heart attacks.

    Teenagers should be discouraged from consuming drinks with a lot of caffeine in them, an expert from the Australia Nutrition Foundation said.

    According to the findings of a new study, telling kids they're smart enhances the idea that intelligence is a genetic gift rather than a skill that ran he improved, and children who think their intelligence is fixed are not likely to pay attention to mistakes and recover from them.

    In the study publisher! online, researchers looked at 123 children who were about 7. The team assessed the children to determine whether they had a “growth mindset（思维定式）”. They asked the children to complete a fast-paced computer task while their brain activities were recorded. During the recording, researchers noted that brain activity stopped within a half-second after making a mistake. The larger the brain response was, the more the child focused on the error.

    Based on the data they collected, the researchers concluded that children with a “growth mindset” were much more likely to have a larger brain response after making a mistake, and in turn were more likely to improve their performance by paying closer attention to the task after making an error.

    For parents, the lessons are clear: for starters, don't pay praises that suggest intelligence is fixed. If a child hands you an A test, don't say “You are smart!” Instead say “Wow, that study really paid off!”

    Second, focus on using errors to work together and learn. Many parents and teachers shy away from mentioning a child's mistakes, telling them “It's OK. You'll get it next time.” without giving them the opportunity to figure out what went wrong. Instead, it's better to tell the child that mistakes happen, and to pay attention and work to figure out where and how they made the mistake.

    “Sesame Street” has been called “the longest street in the world”. That is because the television program by that name can now be seen in so many parts of the world. That program became one of American's exports soon after it went on the air in New York in 1969.

    In the United States more than six million children watch the program regularly. The viewers include more than half the nation's pre-school children, from every kind of economic, racial, and geographical group.

    Although some educators object to certain elements in the program, parents praise it highly. Many teachers also consider it a great help, though some teachers find that problems arise when first graders who have learned from “Sesame Street” are in the same class with children who have not watched the program.

    Tests have shown that children from all racial, geographical, and economic backgrounds have benefited from watching it. Those who watch it five times a week learn more than occasional（偶然的）viewers. In the US the program is shown at different hours during the week in order to increase the number of children who can watch it regularly.

    The programs all use songs, stories, jokes, and pictures to give children a basic understanding of numbers, letters and human relationships. But there are some differences. For example, the Spanish program, produced in Mexico City, devotes more time to teaching whole words than to teaching separate letters.

    Why has “Sesame Street” been so much more successful than other children's shows? Many reasons have been suggested. People mention the educational theories（理论）of its creators, the support by the government and private（私人的）businesses, and the skillful use of a variety of TV tricks. Perhaps an equally important reason is that mothers watch it along with their children. This is partly because famous adult stars often appear on it. But the best reason for the success of the program may be that it makes every child watching feel able to learn. The child finds himself learning, and he wants to learn more.

    Like a lot of health-care professionals, Dr. Brian Goldman finds it extremely difficult to draw boundaries between his work and personal lives. "There's this view that you should suck it up and do one more thing," says the ER physician and host of CBC's White Coat, Black Art. But that "one more thing" often comes at Goldman's expense.

    "You're exhausted and a patient or their family look at you with begging eyes," he says. "So you have this dilemma: say that your shift is over or give until you're totally spent?" Goldman's work stress combined with family tension after his mother was diagnosed with dementia 20 years ago. Caring for her over a decade was difficult, as was dealing with his father's grief. "When someone else is drowning you, you have to grab a life preserver and save yourself," says Goldman.

    Setting boundaries isn't just important for busy professionals; everyone can benefit from managing situations that cause undue stress or pain. Here are some tips.

First, "If someone's behavior makes you unhappy — and it could be anything from the way they speak to you to repeatedly failing to stick to their promise — then there's room to set limits," says Patrick Keelan, a Calgary psychologist. We often avoid setting limits because we prioritize the happiness and comfort of others over ours. In order to control this impulse, Goldman suggests framing the development of boundaries as a form of self-kindness. When facing an overwhelming situation like the one he was in with his father, Goldman suggests reflecting on what is making you feel uncomfortable, unhappy or unappreciated. "You can't relate to others or be kind to others if you aren't kind to yourself," he says.

Second, once you've become aware of your needs, setting and maintaining boundaries requires clear verbal communication. There are three obstacles to enforcing boundaries in a relationship: fear, guilt and self-doubt, says psychologist Nicole MaCance. We often fear that if we set limits, the other person will reject us, or we feel bad claiming our needs. Keelan proposes setting ground rules before relationships become tense. Start by cooperatively listing values — like mutual respect, support, and loyalty — and then building the guidelines from these values. If you're struggling to reach a consensus, Keelan recommends engaging a third party, such as a therapist, to help.

    Now, if you want a boundary to stick to, you can't enable someone in breaking it. As such, it's crucial to establish consequences for  transgressions (越轨). Otherwise, McMance says," you're giving them permission to violate that boundary." If they won't respect your boundaries, you have to do some soul- searching about the value of the relationship. "When you feel bad more than you feel good in this person's presence, and when the relationship is impacting your self-worth and happiness, it's time to reassess," says McCance. Saying no is hard, but she suggests framing it as saying yes to healthier relationships. "We're all better mothers and partners and brothers when we have boundaries."

A Letter that Changed My Life

    I was about 30 years old and was working as a firefighter in the South Bronx's Engine Co. 82. It was a restful Sunday and between alarms I rushed to the office to read a copy of the New York Times. I read an article on the Book Review section which openly stated what I took to be a calumny – that William Butler Yeats had gone beyond his Irishness and was forever to be known as a universal poet. As I read it, my blood began to boil.

    There were few things I was more proud of than my Irish heritage, and ever since I first picked up a book of his poems from a shelf when I was in the military, Yeats had been my favorite Irish writer, followed by Sean O'Casey and James Joyce.

    I grabbed a piece of paper and wrote out a letter of anger to the editor. Throughout Yeats' poetry, his view of the world and the people in it was basically Irish. He had lived his life and written his poetry through the very essence of his Irish sensibility. It was offensive to think Irishness was something to be transcended(超越).

    I don't know why I felt it my duty to safeguard the reputation of the world's greatest poet. I just knew that I had to write that letter.

    After my letter got published, I received a letter from The New Yorker, asking for an interview. When my article Fireman Smith appeared in that magazine, the editor of a large publishing firm called me, asking if I was interested in writing a book about my life. I had little confidence to write a whole book, though the subject was worthy. I wrote Report From Engine Co. 82 in six months, and it sold really well. In the years that followed, I wrote three more best-sellers.

    Being a writer had been far from my expectations. How had it happened? I often found myself thinking about it, and my thoughts always came back to that letter to the New York Times. For me, the writing was a natural consequence of the passion I felt and the subjects represented the great values burning within me as I wrote.

    Over the years, my five children have come to me with one dilemma or another. My answer is always the same. Think about what you're feeling and measure the heat of the fire in your heart, for that is your passion. Your education and your experience will guide you toward making a right decision, but your passion will enable you to make a difference in whatever you do. That's what I learned the day I stood up for Ireland's greatest poet.

    It is rightly said one can share any secret with a true friend. He may know your deepest fears and weaknesses and yet will never take advantage of you. However, keeping a friend's secrets to yourself and not telling the world is what makes the bond grow strong and last forever. You need to develop trust and mutual (互相的) understanding before you start sharing secrets with each other. With friends, secret talks never seem to end and it can get really amusing to know what has been going on in your friend's mind.

    There is a certain time in life especially from the teenage years when one starts having a personal periphery (界限) in life and parents are excluded (排斥) from it. It is because there are certain things that they can't understand and we can't discuss with them. That is when friends become the best secret sharers. They are the ones to whom one reveals one's feelings and best kept secrets.

    It is a general belief that only girls share secrets. But boys have their own secrets that they discuss with only closest friends. The secret talks can range (变化) from relationships, talks about fights with parents, secret activities and anything that is not supposed to be known to others! If you think secrets are limited to only teenagers, get your facts right! Secrets can be shared at any age and there is no hard and fast rule that secrets are shared only among youngsters.

    Sharing secrets with a friend is not just fun, but it also helps to develop a lasting trust in one another. Sometimes, sharing secrets will tell you more about the person. You will come to know whether your friend is reliable and trustworthy and whether it is worth sharing your secrets with them. You can call it a test of friendship.
