In recent years,American teens 【小题1】（earn） less than stellar（优秀的）scores on the national exam. A new analysis from the Center for American Progress argues for one simple step 【小题2】（help）raise these scores:Start school later in the day.

【小题3】（delay）start time by an hour across the country could improve students math scores up to eight 【小题4】（point）, the analysis says. That's almost one grade level of learning. The idea is that giving sleep-lacking teens more time to sleep 【小题5】 they hit the books will help them learn better.

In the previous study conducted in 2012 , middle school students 【小题6】 switched schedules to start school an hour later saw their test scores increase. And among them the low-performing students saw the 【小题7】（big）increase.

The Center for American Progress considered what would happen if those results 【小题8】（repeat） around the country.

“What we found is the impact 【小题9】 student achievement would be quite large,” Ulrich Boster, a senior fellow at the center, told The Huffington Post. “Starting school later could 【小题10】（significant）improve students' outcomes. ”

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.
