In a great many cities, hundreds of people ride bikes to work every day. In New York, some bike riders have even formed a group called Bike for a Better City. They declare that if more people rode bikes to work, there would be fewer automobiles in the downtown part of the city and so less dirty air from car engines.
For several years, this group had been trying to get the city government to help bike riders. For example, they want the city to draw special lanes(车道) for bikes on some of the main streets, because when bike riders must use the same lanes as cars there are accidents. Bike for a Better City feels that if there were special lanes, more people would use bikes.
But no bike lanes have been drawn. Not everyone thinks it is a good idea—they say it will slow traffic. Some store owners on the main streets don't like the idea—they say that if there is less traffic, they will have less business.
The city government has not yet decided what to do. It wants to keep everyone happy. On weekends, Central Park—the largest place open ground in New York—is closed to cars, and the roads may be used by bikes only.

If your child has mobile Internet access, it will be more difficult to monitor(监督) and control his or her Internet use. Kids are turning to the Internet for everything from hanging out with friends to shopping, which makes it harder for parents to keep track of their online activities. Fortunately, there are many choices for controlling what your kids see on their computers, laptops, and mobile devices.
Content blockers and filters are great tools to use for younger kids. They allow you more control over where they go and what they do online. A content blocker can block some unhealthy websites or limit a child's search to the kind of sites. A content filter can scan sites and pictures and block those sites that contain certain words, key phrases, or content.
Consider tracking software for older teenagers. This software enables you to see which sites your children have visited, tracking their paths online. This tool gives young people more freedom to explore the Internet, but it also allows you to check that they are using the Internet responsibly. Let your teenagers know that you trust them, but that you will be regularly checking that they are visiting appropriate sites online.
Even if you use content blockers, filters, and trackers, you know that a lot of kids figure out ways to get around these, so it's important to remain alert (警惕的). Remember that not all adult sites can be identified by blocker, filter, or tracker software. That's why it's important to talk to your kids about what to do when something inappropriate or scary comes up. Nothing can replace involvement and supervision (监督) by adults. Keep monitoring how your kids use the Internet on a regular basis without getting into the role of Internet traffic police.
