members,but new technology will also let them stay in closer touch with those they care about most.I know this from personal experience.E-mail makes it easy to work at home,where I now spend most weekends and evenings.My working hours aren’t necessarily much shorter than they once were but I spend fewer of them at the office.This lets me share more time with my young daughter than I might have.The Internet also makes it easy to share thoughts with a group of friends.Say you do something funny—see a great movie perhaps—and there are four or five friends who might want to hear about it.If you call each one,you will get tired of telling the story.With e-mail,you just write one note about your experience,at your convenience,and address it to all the friends that you think might be interested.They can read your message when they have time,and read only as much as they want to.They can reply at their convenience,and you can read what they have to say at your convenience.E-mail is also an inexpensive way to stay in close touch with people who live far away.Many parents use e-mails to keep in touch,even daily touch,with their children off at college.We just have to keep in mind that computers and the Internet offer another way of staying in touch.They don’t eliminate(排除) any of the old ways.1.The purpose of this passage is to.A.explain how to use the InternetB.describe the
