Aerial performer Jennifer Bricker was born without legs, but she never let it stop her.

    Wrapped in a loop of red silk hung from the ceiling Jennifer Bricker climbs and twists to the music. Her head hangs down and her strong arms let go as she balances on her back, high above the ground a move that's all the more daring because she has no legs.

    Jennifer was a few months old when she was adopted by Sharon and Gerald Bricker. She had big brown eyes, a bright smile, and huge amounts of energy. When a doctor advised her adoptive parents to carry her around in a kind of bucket, they refused.

    Jennifer soon learned to walk — and run — on her hands and bottom, and grew up fearlessly climbing trees and bouncing on the trampoline（蹦床） with her three older brothers. “My parents didn't treat me differently so I didn't grasp the concept that I was different. I knew I didn't have legs but that wasn't stopping me from doing the things I wanted to do.”

    At the age of three she was fitted with artificial legs, but she never really took to them — she moved more freely without.

    In 1996 the Olympic Games took place in Atlanta. Jennifer loved to watch the women's gymnastics team, and especially adored the 14-year-old Dominique Moceanu who competed for the US. When Moceanu and the women's team won gold, Jennifer decided she was going to be a gymnast, too. She took up power tumbling, which involves performing floor exercises down a runway. But Jennifer did not want any allowances to be made for her disability.

    At the age of 10 she took part in the Junior Olympics and by age 11 she was tumbling champion for the state of Illinois.

    Jennifer now travels the world as an inspirational speaker and acts as an aerial performer.

    Doing homework not only can help children master the knowledge they have learned, but also can train their abilities of finishing the work alone, planning the time and doing the duties. But some children don't like to complete the work. Why? There are some reasons.

    Some children feel it is very difficult to do their homework, because they can't understand their teacher clearly, and can't follow their teacher's teaching process. Maybe there is something wrong with their intelligence.

    But some children's intelligence is normal. They are even cleverer, but they don't listen to the teacher carefully. It is hard for them to sit well and pay attention to anything. It needs to carry on the attention centralized（集中注意力）training to help the children.

    Some children love their teacher and then they like the subject. Their interest depends on the teacher who teaches them. So every teacher should be helpful and kind. It can make children love you and the subject you teach. So they can do their homework happily.

    Throughout our daily lives, we have known plenty of people and will know more. But how can we tell if someone is trustworthy? In a paper published recently in the Journal of Personality and Social Psychology, researcher gave us the answer.

    The researchers asked 401 adults from the United States to fill out a questionnaire measuring their guilt-proneness (内疚倾向) in different situations as well as several other qualities, and then play a short online game. In this game, Player 1 is given $1, which they can choose to give to Player2. Any money given to Player 2 is then automatically increased to $2.50. Player 2 can then decide whether to keep all of the money or behave in a trustworthy way by returning a portion of the money to Player 1. The researchers found more guilt-prone people were more likely to share the money with Player 1. Actually, in follow-up studies, guilt-proneness predicted trustworthiness better than other personality qualities the researchers measured.

    Why might guilt lead to trustworthy behavior? The researchers found people who were guilt-prone also reported feeling an obligation to act in ethical (合乎道德的) and responsible ways while interacting (互动) with their partners in the game. People who are guilt-prone tend to avoid engaging in behavior that might harm or disappoint others. If they do something bad, guilt encourages them to try to make things right again.

    Then, how can we use this research to ascertain whether someone is trustworthy? "One way to do this might be observe how they respond to experience regret," lead author Emma Levine, assistant professor at the University of Chicago Levine, explains. Another way is to ask them to describe a difficult dilemma they faced in the past, suggests co-author Taya Cohen, associate professor at Carnegie Mellon University. This is particularly effective, Cohen and her colleagues have found, because it allows us to see if they're concerned about the effects their actions have on others.

The most important thing to keep in mind when deciding to serve another is that service expects no rewards. When you expect something in return, and are not serving out of the goodness of your heart, others will notice. Sure they'll thank you. {#blank#}1{#/blank#}

When you give from your heart, the real power of service comes into play. Serving is a great opportunity to strengthen your trust and respect for another, and for them to do the same to you. Not only do you feel great about helping out, but you build your relationship with them, and they will feel more willing to help you in the future. {#blank#}2{#/blank#}

However, why is service so rarely seen these days? {#blank#}3{#/blank#} Sure, living in this day and age does not leave us much time, and the last thing people want to do is more work. I'm too busy, there's too much work, or I don't have the time, " may run through your head when you hear the word service, but the truth is the benefits are worth the sacrifice. Gandhi once said that, "The best way to find yourself is to lose yourself in the service of others. " {#blank#}4{#/blank#} Some ideas of places you can serve are volunteer centers, nursing homes, boys and girls clubs, and so on. You can serve people as long as you want to.

{#blank#}5{#/blank#} Although it does take some work, the benefits are more than worth the sacrifice. Not only do you feel better about making another's day a little less stressful, but you strengthen your relationship with them and they will be more willing to help you in the future. 

The rejuvenating effects of a restorative nocturnal repose are widely recognized; it can engender a state of enhanced well-being. Academics in the field posit that the excellence of one's slumber may indeed be instrumental in the prolongation of one's lifespan.

Male subjects who enjoy a state of somnolent tranquility could potentially extend their existence by a span of nearly five decades in comparison to those bereft of such repose. The female counterparts stand to gain an increment of two decades. Additionally, it has been observed that youthful individuals who adhere to salutary somniferous routines are less susceptible to a premature demise. However, the mere quantity of repose is insufficient to reap the potential healthful dividends; the caliber of one's slumber is equally pivotal.

The parameters of commendable slumber were delineated by a quintet of distinct criteria. These encompassed an optimal duration of seven to eight hours of repose per nocturnal cycle; experiencing difficulty in the initiation of sleep no more than twice per hebdomadal period; similar challenges in maintaining somnolence no more than twice weekly; abstaining from the consumption of any soporific pharmaceuticals; and awakening with a sensation of invigoration on no fewer than five days per septenary cycle.

The conclusions derived from the study intimate that approximately 8% of fatalities, irrespective of their etiology, could be imputed to inadequate somniferous patterns. Dr. Frank Qian, a resident physician specializing in internal medicine at the Beth Israel Deaconess Medical Center in Boston, America, remarked, "A distinct proportional response relationship was discerned. Consequently, an increase in the beneficial elements pertaining to the quality of sleep correlates with a progressive diminution in mortality from all causes."

The research collated data from a populace of 172,321 individuals with an average age of 50, of which 54% were female. These participants were engaged in the National Health Interview Survey, spanning the years 2013 to 2018, which sought to scrutinize the well-being of the American populace, inclusive of inquiries into their somniferous habits.

The subjects were tracked for a mean period of 4.3 years, during which 8,681 succumbed to death. Of these fatalities, 2,610 (30%) were attributable to cardiovascular afflictions, 2,052 (24%) to oncological disorders, and 4,019 (46%) to a miscellany of other causes. Among the male and female participants who reported adherence to all five indices of quality sleep (an optimal quintile score), the expectancy of life was augmented by 4.7 years for males and by 2.4% for females, in contradistinction to those who possessed none or a solitary factor.

Further scholarly endeavor is warranted to elucidate the raison d'être for the dichotomy in the enhancement of life expectancy, with males exhibiting twice the increment observed in females despite equivalent somniferous quality.

A caveat of the study lies in the reliance on self-reported somniferous habits, which were not subjected to objective quantification or verification.
