Screen Time: How Much Is Too Much?
Many children spend a lot of time watching or playing with electronic media—from televisions to video games, computers and other devices.
Until last year, the American Academy of Pediatrics (AAP) suggested that children and teenagers have no more than two hours of screen time a day. It also suggests that parents balance a child’s screen time with other activities.
Ferguson seems interested in one idea: the link between video games and violent or risky behavior. When he saw results from a recent British survey on screen time, he wanted to know more. The British study found a small negative effect—about a one percent increase—in aggression and depression among children who had six or more hours of screen time a day.
Data from this survey found that American children are also fairly resistant to the negative effects of electronic media. Among those who used screens up to six hours a day, the survey found: a 0.5 percent increase in criminal behavior; a 1.7 percent increase in signs of depression; and a 1.2 percent negative effect on school grades.
| A．Some negative experiences on social media can and do affect some children. |
| B．However, some experts question claims that too much screen time is harmful. |
| C．He wanted to see if there was a similar effect among young people in the United States. |
| D．So, it is natural that parents should wonder about all the time children spend looking at a screen. |
| E．The researchers found no increase in risky sex or driving behaviors, use of illegal substances or eating disorders. |
| F．The researchers suggested that for those children, technology use might get in the way of taking part in other important activities. |

【推荐1】What can a person over 80 do? A group of 33 Japanese grannies can answer this question. The singing and dancing grannies set up a band called KBG84 in 2015. The average age of the members is 84, its oldest member is 97 years old!
The new band, based on the remote island of Kohama in Okinawa, went viral in the country so much so that the members are rather shocked by their success. Their first single, titled Come on and Dance, Kohama Island, has made it to the top of the charts, and they’ve just completed a sell-out tour of Japan.
“We felt like stars in Tokyo,” added 86-year-old Hideko Kedamori. “Everyone in the audience had a big smile, which gave us the energy to sing our hearts out.

Regardless of the songs, these elderly women are very charming when they perform. Their energy and enthusiasm are amazing, in view of their age. In fact, no one under the age of 80 is allowed into the band. It turns out that the pop queens are blessed with incredible genes—Okinawan islanders have one of the highest life expectancies in the world. Their diet chiefly consists of vegetables and local purple-fleshed sweet potatoes, with practically no added sugar. Menaka said she isn’t particular about her diet.

【推荐3】In every school there is a "top" crowd that sets the pace, while the others follow their lead. For example, the top crowd decides that it is smart to wear bright red sweaters. Very soon everybody is wearing a bright red sweater. There is nothing wrong with that, except the fact that bright red is not suitable on some people at all.
The situation can even become dangerous, if the top crowd decides that it is smart to drink or to drive cars at 70 miles an hour. Then the people who follow the lead are causing danger to people's lives. They are like sheep being led to the slaughterhouse (屠宰场）
