As the saying goes, time is money. And in my opinion, time is even precious than money. Why? Because when money is spent, we still have a chance to earn them back. But when time is wasting, we can never get it back. There is no doubt whether time is very limited, and even a minute is of great value. We should make fully use of time to do what should be done. It’s the pity that a lot of people still didn’t appreciate the value of time. They are wasting their time doing nothing of useful. We should form the good habit of race against time and make a difference in our world.

   Parents and teens have long been warned that not getting enough sleep can be unhealthy. However, with the demands of schoolwork, activities and family responsibilities teens often don’t spend enough time on sleep. According to one study, only 15% of teens are getting 8-10 hours of sleep a night they need to function best.

High school English teacher and writer Emily Genser says, “My kids are always asking for nap time! Their lives at home are very stressful. I would be more likely to push for later start times for high school students. They would benefit from another hour of sleep.” Not enough sleep is not only bad for teens’ health, but it can also wreak havoc with their academic (学业的) and athletic performance. It is found that not enough sleep can be linked with drinking, smoking and drug use.

Some high schools are trying a different way. They are allowing tired teens to take a nap in school during the school day in specially designed Energy Pods or just allowing them to spend time in a “quiet room” where technology and conversation are banned. Schools say that a little rest during a packed school day helps students face mounting pressure to get into college.

Because students who sleep better do better and not all of our schools offer nap time, here are some suggestions to help our teens get the sleep they need:

▲Just like in earlier childhood, parents should create a calm atmosphere in the house at bedtime.

▲Encourage a relaxing, regular routine (常规) before bedtime which gives them an opportunity to relax.

▲Persuade them to avoid caffeine after 4 pm.

▲If they do nap, tell them to keep daytime naps less than an hour.

▲Teach them that alcohol and nicotine not only damage their health, but affect their sleep.

▲Show them how regular exercise and a healthy diet promote (促进) good sleep.

HOT on the heels of equality

【小题1】 They lengthen the legs but shorten the steps; they give the wearer a sense of power but can also be painful to wear; they are worn by working women, but their visual appeal has nothing to do with work.

In Japan, a new social media campaign highlights the issues many women have with this footwear. 【小题2】In May, thousands of women signed an online petition(请愿书)demanding that the government ban the practice.

“【小题3】” said the movement founder Yuni Ishikawa, 32 yeas old, in an interview with the Associated Press. “It’s the view that appearances are more important for women at work than for men.”

As early as January, Ishikawa shared her frustration about the unfairness of this dress code on the Instagram social network. In her part-time job as a funeral usher(迎宾员), she was required to wear black heels between 5 and 7cm high.【小题4】. “High heels can cause bunions, blisters and strain the lower back. It’s hard to move, you can’t run and your feet hurt,” Ishikawa wrote in the petition, “【小题5】“

It’s a modest dream. Not too long ago, Japanese businessmen were expected to wear neckties, even on hot days. Then, the government encouraged companies to use less air conditioning and reduce electricity use. Men were freed from neckties. “This petition is the first step toward ‘creating a working environment free from unnecessary burdens’.” Ishikawa said.

Selfie

Social media and the mobile web have given rise to a strange phenomenon called the selfie. But not everyone is familiar with the term, so here’s a brief definition. 【小题1】 Everyone takes selfies, but the younger crowd seems to be especially involved in the trend. Some selfies are extreme close-ups, other show part of an arm held straight outward and a few of the great ones even feature the subject standing in front of a bathroom mirror so that they can get a full body shot of their reflection. 【小题2】 Since social media is the driving force of most selfie activity, younger kids interested in staying connected to their friends, boyfriends, girlfriends, etc. are more active in sharing selfies on a regular basis.

Who knows what kind of psychological factors drive any specific person to take a selfies and upload it to a social networking site. 【小题3】

Here's one. Not only are young people plugged into the web at all times, but they also have more self-esteem issues—and many of these teens or college kids might upload selfies to deal with their own self-consciousness. 【小题4】 When you feel good or look good about yourself, it's far too easy to reach for you phone and document it all through one or several selfies. Kids who are connected on a social network to someone they admire may be more driven to upload attractive selfies as a way to seek attention, especially if they're too shy to do it in person.

Besides, there are people who are bored at work, bored at school, etc. So they will take selfies because they have nothing else better to do. Last but not least, social media is about being social! If that means uploading as many selfies as possible, then so be it. 【小题5】 They just do it because they like to do it, it's fun, and it’s a cool way to sort of document your own life.
