三、阅读理解
The 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 arguments—over a fork,or who had more water in a glass—never 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 don’t 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.I’m afraid it’s bad for them.I do worry that it makes them think it’s 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 don’t teach your children to be alone,they’ll 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 children’s 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 can’t live without electronic devices.
D.Children can’t deal with companionless situations.

Dear Sir/Madam，
I'm Li Hua.I'm delighted to learn that volunteer students are wanted for a Chinese painting exhibition to be held in the local art gallery.Now I'm writing to apply for the position.
First of all，having been exposed to foreign teachers since a young age，I can communicate freely with others in English.What's more，years of being monitor makes me a brilliant organizer.The most important factor is that my related knowledge will undoubtedly help the audience learn more about the unique Chinese art form.
All in all，my sense of responsibility will make me a qualified volunteer.I'd appreciate it if you could take my application into consideration.
Yours，
Li Hua
