5 . The expression, “Everybody’s doing it,” is very much at the center of the concept of peer pressure. It is a social influence applied on an individual in order to get that person to act or believe in a(n) ______ way as a larger group. This influence can be negative or positive, and can exist in both large and small groups.

People are social creatures by nature, and so it is hardly ______ that some part of their self-respect comes from the approval of others. This instinct explains why the approval of peers, and the fear of ______, is such a powerful force in many people’s lives. This instinct drives people to dress one way at home and another way at work, or to answer a simple “fine” when a stranger asks “How are you?” even if it is not necessarily true. There is a(n) ______ aspect to this: It helps society to function efficiently, and encourages a general level of self-discipline that ______ day-to-day interaction between people.

Instead, people should seriously consider why they feel drawn to taking a particular action, and whether the real ______ is simply that everyone else is doing the same thing.

6 . Grandparents Answer a Call

As a third－generation native of Brownsville, Texas, Mildred Garza never planned to move away.Even when her daughter and son asked her to move to San Antonio to help with their children, she politely refused.Only after a year of friendly discussion did Ms.Garza finally say yes.That was four years ago.Today all three generations regard the move as a success, giving them a closer relationship than they would have had in separate cities.

No statistics show the number of grandparents like Garza who are moving closer to adult children and grandchildren. Yet there is evidence suggesting that the trend is growing.Even President Obama’s mother-in-law, Marian Robinson, has agreed to leave Chicago and move into the White House to help care for her granddaughters. According to a study by grandparents.com, 83 percent of the people said Mrs.Robinson's decision will influence grandparents in the American family.Two－thirds believe more families will follow the example of Obama’s family.

“In the 1960s we were all a little wild and couldn't get away from home far enough or fast enough to prove we could do it on our own,”says Christine Crosby, publisher of Grand, a magazine for grandparents. “We now realize how important family is and how important it is to be near them, especially when you’re raising children.”

Moving is not for everyone. Almost every grandparent wants to be with his or her grandchildren and is willing to make sacrifices, but sometimes it is wiser to say no and visit frequently instead.Having your grandchildren far away is hard, especially knowing your adult child is struggling, but giving up the life you know may be harder.

7 . Kindness is seen as a true strength, and the success of civilizations relies on kindness. As parents and teachers, we also teach children from a young age to “be kind to one another” and “treat others the way you want to be treated.”

In addition to being helpful to our interpersonal relationships, research has shown that kindness can even contribute to our well-being. According to the Mayo Clinic, when we perform acts of kindness, the pleasure center in our brain is activated, releasing the stress-reducing hormone (激素). Individuals who volunteer on a regular basis report greater life satisfaction. And what is even greater is that kindness rarely stops with just one person. There can be a positive contagion (扩散) effect, where other people are motivated to be nice if they receive a random act of kindness. The question then arises: Could kindness be harmful to us when it has such clear benefits? Let’s think about this in the workplace or in an organization.

You are the new person on the team and you want to be well-liked and respected by your colleagues. You are a kind person and tell your team, “Let me know how I can help you; I’m always available to help.” Though you may truly mean this, there are unfortunately people in this world who can see your kindness as a weakness. This can lead to you being taken advantage of by others.

Let’s fast forward a year. You have been in your position now for one year, and you are working with the same team. You are noticing that your colleagues continue asking for your help over and over again. In fact, the only time they communicate with you is when they need something. You have been so helpful to your colleagues and there has rarely been any return from them.

In a very broad sense, it is advantageous to be kind to others, and your kind acts will be appreciated and, perhaps, paid forward. However, you need to be willing to say “no”. Recognize when your plate is already too full. When people ask you a favor, assess if you have the time, energy, and attention to give to them. To truly be kind, sometimes you need to be more comfortable saying “no” to others and saying “yes” to yourself.

9 . Binge-watching (刷剧) is when a person watches more than one episode of a show in a row. With developments in the speed and connectivity of the Internet, increases in technology and the rise of on-demand entertainment companies, people can now have their favorite shows stream (流播) directly to their television at their convenience.

This behavior is nothing new. In fact, binge-watching has been officially listed in dictionaries since 2015. The entertainment companies recognize this behavior and many take steps to encourage it. Often, instead of releasing each episode on a week-by-week basis, an entire series will become available concurrently. Once the episode finishes, many platforms will display pop-ups with “you might like” suggestions, or will automatically play the next episode.

However, recent research suggests that out of the more than half of British adults who watch more than one episode of a show back-to-back (一集接一集地), almost a third have admitted missing sleep or becoming tired as a result; and 25% have neglected their household chores (家务活). Next we’ll be missing work!

Bingeing has other connections — binge eating, binge drinking and binge smoking. All of them are often associated with a lack of control and a possible route to addiction. Lindsey Fussell, consumer group director, said, “The days of waiting a week for the next episode are largely gone, with people finding it hard to resist (抗拒) watching multiple episodes around the house or on the move.” If people find binge-watching hard to resist, are we witnessing the birth of a new type of addiction?

The countless number of information and entertainment that television and online media can bring us is, many would say, a good thing. However, when the activity begins to bleed into other areas, causing us to stop functioning, then it becomes a problem. So, what’s the answer? Moderation! Neither a tiny amount, nor too much. After all, as the old proverb says, “A little of what you fancy does you good.”

10 . Getting less sleep has become a bad habit for most American kids. According to a new survey(调查) by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.

How much sleep you need depends a lot on your age. Babies need a lot of rest: most of them sleep about 18 hours a day! Adults need about eight hours. For most school-age children, ten hours is ideal(理想的). But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime? Watch TV.

“More children are going to bed with TVs on, and there are more opportunities(机会) to stay awake, with more homework, the Internet and the phone,” says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing levels of body chemicals called hormones not only make teenagers’ bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.

Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago, schools in Edina, Minnesota, changed the start time from 7:25 am to 8:30 am. Students, parents and teachers are pleased with the results.
