"It's a big hammer to crack a nut．"This is how one angry parent described the recent crackdown（强制措施）by London police on parents who drop their kids off at school by car．Yes，you read that correctly-the very mode of transportation that many American schools insist-the only safe way to deliver kids to school is now being criminalized in the United Kingdom． The decision to fine any vehicles seen dropping off or picking up kids within a particular zone of east London comes from city councillors"（议员） long-term efforts to make the area safer and less crowded．They say they've been trying for years"to encourage sensible driving and parking"，but in vain．Neighborhood residents complain frequently about their driveways being blocked by illegally parked cars for 15minutes or more，often while they're trying to get to work，and the streets are long overcrowded． Now the rules have changed．Some parents are angry．Angie Baillieul is a mother who made the"big hammer"comment and says the crackdown is"way over the top．"The nearest drop-off point for her six-year-old is now a five-minute walk from the school．Others are happy with the decision，severe though it may seem．Councillor Jason Frost said，"Traffic has significantly reduced，and more children are now walking to school，which is a great outcome．I would rather have complaints that we are slightly inconveniencing parents than hear that a child had been seriously injured because nothing was done．" I witness daily the chaos created by these in-town drivers，when I walk my own kids to school．There's a parking lot overflowing with vehicles and a slow-moving train of cars moving in circles，many filling the air with harmful smokes．Meanwhile，the conversations around child over-weight and the importance of daily physical activity continue to stand out in schools．

Millions of teenagers are in danger of putting their health at risk by getting hooked on e-cigarettes，experts warn．Leading health researchers say they are"very concerned"by the growing number of youngsters trying the devices． Ecigarettes have been marketed as a healthier alternative to smoking conventional cigarettes．But previous research shows ecigarettes generate poisonous chemicals similar to those found in tobacco and may harm the lungs and immune system． Worryingly，researchers at Liverpool University discovered 16% of teenagers who have used ecigarettes had never previously smoked．The experts also found ecigarettes were"strongly related"to drinking among teenagers．Study author Prof．Mark Bellis said，"Our research suggests that we should be very concerned about teenagers accessing ecigarettes．While debate on ecigarettes has focused largely on whether or not they act as a gateway to tobacco cigarette use，ecigarettes themselves contain a highly addictive drug that may have more serious and longer lasting impacts on children because their brains are still developing．" Researchers surveyed 16，000students aged 14to 17in the North West of England and asked them about their alcohol and tobacco use．They found that one in five answered yes to the question："Have you ever bought or tried electronic cigarettes？"More males than females said they had． Of the teenagers that had accessed ecigarettes，16% had never smoked，23% had tried smoking，12% only smoked when drinking，and 14% were exsmokers．The research also found teenagers who drank alcohol were significantly more likely to have accessed ecigarettes than nondrinkers． Among those who had never smoked，it was found that those who regularly have excessive（过多的）drinking were four times more likely to access ecigarettes than those who never drink．In all of those that drink，regardless of smoking status，ecigarette access was associated with excessive drinking and involvement with violence after drinking．The researchers said their findings suggest that teenagers who use ecigarettes are most susceptible to other forms of substance use and risktaking behaviors．
