     Modern family life is improved on many levels by numerous advances in technology. However, sometimes the high-tech tools designed to bring us closer together, such as smart phones and computers, can actually distance us from one another. If your family members are becoming increasingly disconnected（疏远）as a result, it may be time to establish some effective time-management rules. 
     The family dinner table should be a tech-free zone. Make a firm rule that there will be no talking on phones, text-messaging or watching television during dinner time. That is the ideal opportunity for the family to reconnect after a busy day. 
     The only way to ensure that family members, especially children, obtain adequate sleep, fresh air and exercise is to limit the amount of time they spend playing video games, surfing the web or text-messaging friends. A well-balanced, healthy life can only be achieved by monitoring time spent on using high-tech tools. 
     For school-age children it might be wise to have rules regarding technology. To ensure that they are being mindful of their studies and getting adequate sleep on school nights, you might make a schedule banning video games except on weekends and banning exciting television programs immediately before bedtime. Children require help in keeping their lives in balance, especially in regard to addictive（使人上瘾的） games and television viewing.
     Monitor your own activities in regard to modern technology. If you are at the dinner table with a cell phone in your ear, or have one eye on the television, you cannot expect your children to behave otherwise.
