Understanding Ideas 教师：李学慧 班级：73/74/78 B1U4 Warming-up 黄鹤楼送孟浩然之广陵 [唐] 李白 故人西辞黄鹤楼， 烟花三月下扬州。 孤帆远影碧空尽， 唯见长江天际流。 Did Meng Haoran “click” for new friends? A. Make a friend face to face. B. Make a friend online. C. Make a friend letters. 1 How would you feel if moving to a new town meant losing track of your friends?What if the only way of getting news from faraway friends was writing letters that took ages to be delivered? This was how things worked not very long ago. Thanks to advances in technology, how we make friends and communicate with them has changed significantly. 2 Nowadays, we can move around the world and still stay in touch with the people that we want to remain friends with. Social media tools let us see what our friends are up to and maintain friendships. All you need is a wi-fi connection. 3 The digital age also enables us to find people who share our interests, such as collecting model cars or playing an unusual instrument.Whatever our hobbies, the Internet can connect us with others who also enjoy doing them,even if they live on the other side of the world. 4 But when you "friend"people online, does this mean that they really are your friends? 5 It depends. 6 If people always exchange true personal information online, then yes, these friendships can be real and meaningful. But we need to keep in mind that what we see on social media is often not the whole truth about a person. 7 On social media sites, people tend to post only positive updates that make them appear happy and friendly. But smiling photos can hide real problems. Remember the saying; on the Internet, nobody knows you're a dog. A young person could be old; a woman could be a man;we could even be sharing our information with criminals. 8 But this doesn't mean that we should throw the baby out with the bathwater. Although technology has changed the way we acquire friends, the meaning of friendship and our longing for friends remain the same. As Aristotle said, no one would choose to live without friends, even if he had all other goods.
