Students in France have one less thing to put in their backpacks these days. The country recently banned(禁止)smart phones in public schools for all students through ninth grade. Many schools around the United States have similar bans.

Some educators say kids pay better attention in class when they aren't constantly(始终)looking at their phones. They say banning phones encourages students to talk to cach other more.

Most teachers would agree that they don't want a classroom full of kids texting. But many say a total ban on phones isn't necessary. Some people argue that it is better to teach kids to use technology responsibly(负责任地)than take it away. Plus, many parents point out that they need to be able to reach their kids during the day.

Group Yes

★Smartphones make it difficult for students to concentrate(聚精会神)in class. Kids might play games, watch videos, or check out apps instead of paying attention to the teacher. They can easily miss important information. Plus, a ringing or buzzing phone distracts other students.

★Also, some kids might use their phones to cheat. They could go online and look up answers to a text, or they could text their friends for help.

Group No

★Students should be able to have their phones with them in case of an emergency(紧急情况). Kids need a way to get in touch with their parents if they get sick, if the school bus breaks down, or even if they forget their lunch at home.

    Lily was a French girl who moved to America with her family. She left school at the age of 16. She had to work to support her family. Her English was very poor. She didn't have the courage to ask for a job.

One day, Lily saw a sign at a company."Help wanted," the sign said. She walked up to the office and knocked on the door. She was met by the office manager, Margaret Costello. In her broken English.
