Trapped on the 37th Floor

Melinda Skaar wasn't expecting any phone calls.Skaar was working late in her office at the First Interstate bank of California.By 10:45 that night she was almost ready to go home when the phone rang.

Picking it up，she heard a guard shouting.“There is a fire! Get out of there!”

Skaar didn’t panic.She figured that it was just a small fire.Her office building was huge.There were 62 floors and her desk was on the 37th floor.

Skaar called out to office mate Stephen Oksas.who also stayed late to work.But when they got to the hallway, they were met by a cloud of black smoke.Rushing back，Skaar shut the door and filled the space at the bottom of the door with her jacket to keep the smoke out.

Then they called 911.Before they could call their families，however, the line went dead.That meant that they were completely cut off from the outside world.All they could do was wait and hope someone would come to rescue them.

Minutes ticked by.Smoke began to float into the office.Soon it became hard for them to breathe.

Looking around，Skaar noticed a small workroom.It seemed to have cleaner air.So they crowded there.That helped for a while，but in time even the workroom was filled with deadly smoke.

Hopeless，they tried to break the windows，but the glass was not breakable.Everything they threw at just bounced back.

Defeated，they struggled back to the workroom.They felt weak and dizzy.Soon Skaar found Oksas had passed out.

As Skaar and Oksas lay near death，rescuers were rushing to find them.At last，at about 4 a.m.，firefighters found them.

Earlier this year，my oldest daughter got braces(矫正器)on her teeth，and let’s just say she did not go quietly into that dentist’s chair.Fear and hate pretty much describe the days leading up to her first appointment.

So when she finally walked out with shiny teeth，a sore(疼痛的)mouth and a broken spirit，I told her I was proud of her and took her to Ben &Jerry’s for an ice cream reward.Two weeks later，we returned to the scene of the crime.The dentist spent about 45 seconds checking her teeth before sending her on her merry way.Before I could start the car, she was placing her ice cream order.She was shocked when I told her that she wasn't going to get a reward every time we get her teeth checked.

Clearly，she’s not alone.According to some parenting experts，kids are easily addicted to a benefit—producing system of parental rewards and bribes—it’s not all ice creams，candies and cool toys.Some parents are offering their children prizes to just let them sit down and behave in a restaurant—or sleep in their own beds—or score a goal in the next soccer game.

While the experts agree that occasional awards are okay, the danger lies in the system’s overuse.Kids quickly gain a sense of entitlement(应得的权利)，where they come to expect a big reward for every good thing that they do，no matter how small.To keep things in check，experts say parents should reduce the number of rewards they offer，make sure rewards match the behavior and explain the real benefits of behaving for the sake of behaving.
