And when you have time, you may simply eat snacks like potato chips.    1    In fact, if you have a busy schedule, it’s even more important to eat healthy foods that give you the energy you need to keep going.

    2    For example, you may feel hungry in a long afternoon of classes or during your swim meet. Knowing how much food your body needs to satisfy this hunger is important. A few walnuts(核桃) are great brain food before sitting down to do your math homework.    3    

Healthy snacking is important to you. During teenage years, the body needs more nutrients to grow. Snacks are a great way to satisfy your hunger and get all nutrients your body needs.    4    Do not eat foods with lots of added sugars like candy bars or soda. That’s because eating these foods may help you stop feeling hungry for a moment, but they are bad for your health in the long term.

Choosing healthy snacks means shopping smart.    5    We may find “all natural” on the side of a package but it doesn’t necessarily mean it’s nutritious. For example, “all natural” juice drinks can be filled with sugar, which means they’ll make you fat easily and give you little nutrition.

【推荐1】We don't choose our siblings（兄弟姊妹）the way we choose our partners and friends. Of course，we don't choose our parents either，but they usually make that up to us by accompanying us on the way to adulthood. Brothers and sisters are just sort of there. And yet，when it comes to our development，they can be more influential than parents.

Whether these relationships make our life better or worse is a more complicated question. On the upside，positive interactions with siblings during adolescence foster（培养）empathy，prosocial（亲社会的）behavior，and academic achievement. However，when a sibling relationship is bad，it can be really bad. Tense sibling relationships make people more likely to be depressed and anxious in adolescence. Moreover，sibling bullying makes a kid involved in self-harm as a teen and develop mental problems in adulthood.

Whether a person models himself after his siblings or tries to distinguish himself has particularly important consequences. One study found that siblings who felt positive about each other tended to achieve similar education levels while those who spent unequal time with their dad and got unequal parental treatment had different educational fortunes. That difference is changeable. One the one hand，as siblings' relationships with their parents grow more different over time，their relationship with each other may become warmer. On the other hand，following your sibling can be a mistake: teenagers are more likely to be involved in risky behavior if an older sibling did so first.

One way or another，sibling influence is lasting. A study of more than 1 million Swedes found that one's risk of dying of a heart attack multiplies after a sibling dies of one，due not only to shared DNA but also to the stress of losing such a key figure. The findings make sense: Most of us are different people than we’d have been if our brothers or sisters were never born.

【推荐2】Mariah, 35, was a single mother. She had four kids under the age 9, and was hardly keeping up payments on her small two-bedroom home by working extra weekend hours as a waitress. There were times when she lay in bed and cried. She didn’t know how she could pay that bill. But she knew she must find a way to change her life.

She knew how hard it was to mop(拖)the floor. “I was tired of bending down, putting my hands in dirty water and wringing (拧)out a mop,” Mariah says. “So, I got a better way.” How about a “self-wringing” mop? She designed a special tool. You could twist in two directions and still keep your hands clean and dry.

She set out to sell her mops, but the mops didn’t sell well at the market. Then Mariah met with the media. But would people buy a mop by reading an advertisement? They gave it a try, and it failed. Mariah was sure it would sell well if they let her do the on-camera show. “Get me on that stage, and I will sell this mop because it’s a great thing,” said Mariah. So QVC let her have a try. “I got on the stage and the phones went crazy. We sold every mop in minutes.”

Today Mariah is the president of Ingenious designs, a multimillion-dollar company, and one of the stars of HSN, the Home Shopping Network. Talking about hr household inventions is as natural for her it is for parents to talk about their child.

Today one of her favorite products is Huggable Hangers(衣架). The thin, space-saving tool are the most successful goods ever sold on HSN, with 100 million hanging out in closets across the country.
