other day,my sister and I were sitting in a restaurant,trying to have a conversation,but her children,four-year-old Willow and seven-year-old Luca,would not stop fighting.The argumentsover a fork,or who had more water in a glassnever stopped.Then my sister reached into her handbag,produced two shiny iPads(苹果平板电脑),and handed one to each child.Suddenly,the two were quiet.They sat playing games and watching videos,and we continued with our conversation.After our meal,as my sister sniffed the iPads back into her bag,shesaid,“I dont want to give them the iPads at the dinner table,but if they keep them occupied for an hour so we can eat in peace,I often just hand them over.Im afraid its bad for them.I do worry that it makes them think its OK to use electronics at the dinner table in the future.”Dr.GarySmall,director of the Longevity Centre at the University of California,Los Angeles says that the brain is highly sensitive to stimuli(刺激物),like iPads and smartphone screens,and if people spend too much time on one technology,and less time interacting(互动) with people like parents at the dinner table,that could prevent the development of certain communication skills.“Conversations with each other are the way children learn to have conversations with themselves,and learn how to be alone,”said Sherry Turkle,a professor of science,technology and society at the Massachusetts Institute of Technology.She fears that children who do not learn real interactions,which often have imperfections,will come to know a world where perfect,shiny screens give them a false sense of intimacy(亲密) without risk.However,they need to be able to gather themselves and know who they are.So someday they can form a relationship with another person without a panic of being alone.“If you dont teach your children to be alone,theyll only know how to be lonely,”she said.1.What did Willow and Luca fight about?A.iPads.B.Little things.C.Delicious food.D.Interesting things.2.According to Dr.Small,what should parents do?A.Provide their children with various technologies.B.Teach their children communication skills.C.Talk to their children at the dinner table.D.Limit their childrens screen time.3.What is Sherry Turkle worried about?A.Children are afraid of taking risks.B.Children try to escape from the real world.C.Children cant live without electronic devices.D.Children cant deal with companionless situations.四、应用文写作假定你是李华，暑假在伦敦学习，得知当地美术馆要举办中国画展。请写一封信申请做志愿者，内容包括：1写信目的；2.个人优势；3.能做的事情。注意：1词数80左右；2可以适当增加细节，以使行文连贯；3开头和结尾已为你写好，但不计入总词数。Dear
