“Sorry for keeping you waiting. I left my cell phone at home, so I went hack to get it,” Adam said as he apologized to Vicky after arriving an hour late for their first date. Vicky tried to be polite, so she forced a smile and replied, “It's all right. Let's order something to eat.” While they were waiting for their food. Vicky discovered that Adam had been checking his cell phone. Just as she got the chance to talk to him Adam's cell phone rang and he answered it without delay. He talked continuously and totally ignored his date, who was sitting right next to him. Twenty minutes later, when Adam finally hung up and turned hack to Vicky, he saw nothing but an angry face. “Why don't you date your cell phone?” said Vicky. Then, she stood up and shouted, “Don't ever call me again!”
We can understand why Vicky was so angry at Adam. In fact, like Adam, many people in modern society can't stand to be separated from their cell phones. With their cell phones, they talk to others, listen to music, check e-mall, and download applications as well as photos. Their dependence on this technological device has become so great that the cell phone is now often considered a necessity rather than a luxury (奢侈品). Some people cannot even imagine life without their cell phones. As a result, a psychological(心理学的) phrase known as "disconnect anxiety" was born.
According to psychologists, when these people are not using their phones, they may start to feel uneasy. Some feel socially separated without their cell phone. Others worry about not being able to respond to emergencies in time. Still others are so psychologically influenced by their cell phones that they often believe their phones have been ringing without their knowledge. Those who suffer from disconnect anxiety frequently check their cell phones for any missed calls or messages. In addition, they like to keep in touch with their friends-even just to kill time. What's more, if these heavy cell phone users discover that they have forgotten to bring their cell phones along with them, they will insist on returning home to get their "cells".
It's nice to have a cell phone, and it makes sense, of course, to enjoy all the advantages this clever product has brought. However, we need to use it wisely. For example, when we are doing something important, we should turn off our cell phones to concentrate on our work. As for Adam, he had better leave his cell phone at home on his next date with Vicky-if he gets another chance to go out with her!
A fresh-faced batch of teenagers just began a new school year, but will they get the most out of it? In the mornings, many are forced to get to school much too early. And at night, screens are a temptation that's hard to resist. This double whammy (双重灾难) is a perfect lesson in sleep deprivation (剥夺).
Three out of every four students in grades 9 to 12 fail to sleep the minimum of eight hours that the American Academy of Medicine recommends for their age group. In most cases, insufficient sleep results in reduced attention, preventing students' progress and lowering grades. More alarmingly, sleep deprivation may lead to physical and emotional problems.
It is important to understand why teenagers have a particularly hard time getting enough sleep, and what adults need to do to help. First, a reminder of the basic biology: Adolescents are no longer the morning larks of their younger years. They become rewired as night owls, staying awake later and then sleeping in. This is mostly driven by changes in the way the brain responds to light.
New technology habits aren't helping. More teenagers now turn to activities involving screens at night. The growth in screen time is particularly problematic for sleep. The blue light emitted by LEDs, TVs, tablets and smartphones suppresses the body's secretion (分泌) of melatonin, the hormone that signals it's time to sleep. Overdosing on screens at night effectively tells the brain it's still daytime, delaying the body's cues to sleep even further.
Parents should inform their kids of the time that can be spent on screens, and praise children who show signs of regulating their own media consumption. In the hour before bedtime, there should be a suspension on bright lights in the home, avoiding devices and harsh LED bulbs in kitchens and bathrooms.
In 2016, the American Academy of Pediatrics recommended that middle and high schools start no earlier than 8: 30 a. m., a policy now backed by the American Medical Association and many other health organizations.
Parents also need to join forces with community leaders, sleep scientists, health professionals and educators to put school start times on the local, then state agendas.
Whenever schools have managed the transition to a later start time, students get more sleep, attendance goes up, grades improve and there is a significant reduction in car accidents.
