Forty percent of teens say they have been hit or nearly hit by a car，motorcycle or bike while walking，according to a new report released by the Safe Kids Worldwide organization.

Safe Kids Delaware has released a list of safety tips children and teens should follow in order to remain safe while walking. The group said it is important to put down phones and remove headphones while crossing the street，make eye contact with drivers before crossing，and remain visible to drivers even in the dark.

"We all know about the dangers of distracted（思想不集中的）driving，but we need to talk to our children，especially teens，about the dangers of walking while they are distracted by using technology like listening to music with headphones on，and texting on cellphones，"said Kim O'Malley，the pedestrian（行人）safety conductor for Safe Kids Delaware.

Teens on the Moue is the name of the report，which explores the walking behavior of  1，040 teenagers between the ages of 13 to 19.Half of the surveyed teens admitted they were distracted by a mobile device while crossing the street. The study also found that more often than not，those who were hit or nearly hit had not been using a crosswalk（人行横道）or had been running across the street.

Safe Kids Worldwide reports that the death rate for teens aged 13 to 19 is nearly three times higher than that of 5-to 12-year-olds.In Delaware，seven teenagers aged 15 to 19 have been killed in pedestrian crashes in the last three years，and another 123 have been injured. By comparison，just two children aged 5 to 9 were killed at that time and another 79 were injured. The new report expands on findings from a similar one in 2015 that showed one in five high schoolers and one in eight middle schoolers crossed the street while distracted by using technology.

   Everybody sleeps，but what people stay up late to catch or wake up early in order not to miss varies by culture.

From data collected，it seems the things that cause us to lose the most sleep，on average，are sporting events，time changes，and holidays.

Around the world，people change sleep patterns thanks to the start or end of daylight-saving time（夏令时间）. Russians，for example，began to wake up about a half-hour later each day after President Vladimir Putin shifted the country permanently to“winter time”starting on October 26.

Russia's other late nights and early mornings generally correspond（相一致）to public holidays. On New Year's Eve，Russians have the world's latest bedtime，hitting the hay at around 3:30 a. m.

Russians also get up an hour later on International Women's Day，the day for treating and celebrating female relatives.

Similarly，Americans' late nights，late mornings，and longest sleep fall on three-day weekends.

Canada got the least sleep of the year the night it beat Sweden in the Olympic hockey（冰球）final.

The World Cup is also chiefly responsible for sleep deprivation. The worst night for sleep in the U. K. was the night of the England-Italy match on June 14. Brits stayed up a half-hour later to watch it，and then they woke up earlier than usual the next morning thanks to summer nights，the phenomenon in which the sun barely sets in northern countries in the summertime. That was nothing，though，compared to Germans，Italians，and the French，who stayed up around an hour and a half later on various days throughout the summer to watch the World Cup.

It should be made clear that not everyone has a tool to record their sleep patterns；in some of these nations，it's likely that only the richest people do. And people who elect to track their sleep may try to get more sleep than the average person. Even if that's the case，the above findings are still striking. If the most health-conscious among us have such deep swings（明显改变）in our sleep levels throughout the year，how much sleep are the rest of us losing？

A. They have trouble falling asleep.

【小题4】What does the author imply in the last paragraph?
A. Sleeplessness does harm to people's health.
B. It is important to study our sleep patterns.
C. Few people really know the importance of sleep.

   Common Sense Media，a group that helps children，parents and teachers better understand media and technology，did a study. It paid attention to all kinds of media-related activities，from old methods like reading and listening to the radio，to new favorites like using social media and video chatting. More than 2，600 kids were surveyed. Here are some truths and myths（错误观念）the study found：

Truth 1：Some teens spend too much time looking at screens.

One in five teens spends more than six hours on screens each day，and 18%of teens are looking at their screens for more than 10 hours a day. Often they watch television on one while chatting with friends on another.

Myth 1：This is the end of reading.

The average（平均的）time young people spend reading，either in print or on a screen，is only 30 minutes a day. However，kids who received the survey say reading is one of their favorite activities.

Truth 2：Boys prefer video games while girls prefer social media.

Among teen boys，71% enjoy playing video games，twice as many as teen girls. And while more than 25%of teen boys list playing video games as their favorite media activity，only 2%of teen girls do.

What's more，teen girls spend about 40 minutes more each day on social media than boys do.

Myth 2：TV and music have been muscled out（强行逐出）.

For teens，TV is still the top media activity. They enjoy it most and watch it every day. In fact，47%of teens have TV sets in their bedrooms. For teens，while 57%have TV sets in their rooms，music is the main form of amusement. However，only about a third listen to music on the radio. Most teens listen to it on their smartphones.

Note: You are a teen if you are between 13 and 19 years old，while a tween is a child between the ages of 10 and 12.

It was once common to regard Britain as a society with class distinction. Each class had unique characteristics.
In recent years, many writers have begun to speak of the ‘decline of class ’ and ‘classless society ’ in Britain. And in modern day consumer society everyone is considered to be middle class.
But pronouncing the death of class is too early. A recent wide-ranging study of pubic opinion found 90 percent of people still placing themselves in a particular class; 73 percent agreeed that class was still a vital part of British society.; and 52 percent thought there were still sharp class differences. Thus, class may not be culturally and politically obvious, yet it remains an imprtant part of British society. Britain seems to have a love of stratification.
One unchanging aspect of a British person’s class position is accent. The words a person speaks tell her or his class. A study of British accents during the 1970s found that a voice sounding like a BBC newsreader was viewed as the most attractive voice. Most people said this accent sounds ‘educated ’ and ‘soft ’. The accents placed at the bottom in this study, on the other hand, were regional(地区的) city accents. These accents were seen as ‘common ’ and ‘ugly ’. However, a similar study of British accents in the US turned these results upside down and placed some regional accents as the most attractive and BBC English as the least. This suggests that British attitudes towards accent have deep roots and are based on class prejudice.
In recent years, however, young upper midder-class people in London, have begun to adopt some regional accents, in order to hide their class origins. This is an indication of class becoming unnoticed. However, the 1995 pop song ‘ Common People ’ puts forward the view that though a middle-class person may ‘ want to live like common people ’ they can never appreciate the reality of a working class life.
