单选题As I type these lines, my daughter, Harriet, who is 14, is on her iPhone skipping among no fewer than eight social media sites. My son, Penn, who is 15, will be asleep for hours yet. He was 1 all night with a friend playing two video games, in a jag fueled by his favorite foodlike 2 . I like that my kids are comfortable and alert in the wired world. But increasingly I am 3 for them. It"s more 4 every day that screens have gradually stolen them from themselves. My wife, Cree, and I have 5 them to drift quite distantly into the online world, and we fear our casualness has been a 6 . Each summer Cree and I resolve to 7 things back. This is 8 we draft rules for a new school year, strictures like: no laptops in bedrooms during the week; homework before screen time; no electronics after 10 p.m.. These rules invariably begin to 9 by Day 3. By Day 4, there is pleading, and the discreet slamming of doors. By Day 8, no one is sure what the 10 are anymore. We"re back where we started, and plump with fear. This year it 11 to me we needed help. So I sat down with a new book that 12 assistance, and understanding. It is The Big Disconnect: Protecting Childhood and Family Relationships in the Digital Age, whose primary 13 , Catherine Steiner-Adair, is a clinical psychologist who teaches at Harvard Medical School. Her book is 14 on thousands of interviews, and it can be eloquent about the need to ration our children"s computer time. Here the author has pinned me. I like to think I"m a good father, perhaps even casually 15 in my better moments, 16 there is zero doubt that, without my iPhone in my palm, I feel I lose something since I"m fairly 17 . I must change my life a bit. Cree and I are still hammering out our kids" computer rules. We are trying to 18 in mind that we"re not our kids" best friends; we"re their 19 . And we are 20 if there"s an app for fortitude.

单选题 The lives of very few Newark residents are untouched by violence: New Jersey's biggest city has seen it all Yet the murder of three young people, who were forced to kneel before being shot in the back of the head in a school playground on August 4th, has shaken the city. A fourth, who survived, was stabbed and shot in the face. The four victims were by all accounts good kids, all enrolled in college, all with a future. But the cruel murder, it seems, has at last forced Newarkers to say they have had enough. Grassroots organizations, like Stop Shootin’, have been flooded with offers of help and support since the killings. Yusef Ismail, its co-founder, says the group has been going door-to-door asking people to sign a pledge of non-violence. They hope to get 50000 to promise to "stop shootin’, start thinkin’, and keep livin’." The Newark Community Foundation, which was launched last month, announced on August 14th that it will help pay for {{U}}Community Eye{{/U}}, a surveillance (监视) system tailored towards gun crime. Cory Booker, who became mayor 13 months ago with a mission to revitalize the city, believes the surveillance program will be the largest camera and audio network in any American city. More than 30 cameras were installed earlier this summer and a further 50 will be installed soon in a seven-square-mile area where 80% of the city's recent shootings have occurred. And more cameras are planned. When a gunshot is detected, the surveillance camera zooms in on that spot. Similar technology in Chicago has increased arrests and decreased shootings. Mr. Booker plans to announce a comprehensive gun strategy later this week. Mr. Booker, as well as church leaders and others, believes (or hopes) that after the murder the city will no longer stand by in coldness. For generations, Newark has been paralyzed by poverty— almost one in three people lives below the poverty line—and growing indifference to crime. Some are skeptical. Steve Malanga of the conservative Manhattan Institute notes that Newark has deep social problems: over 60% of children are in homes without fathers. The school system, taken over by the state in 1995, is a mess. But there is also some cause for hope. Since Mr Booker was elected, there has been a rise in investment and re-zoning for development. Only around 7% of nearby Newark airport workers used to come from Newark; now, a year later, the figure is 30%. Mr Booker has' launched a New York-style war on crime. So far this year, crime has fallen 11% and shootings are down 30% (though the murder rate looks likely to match last year's high).
