阅读理解

    It should come as no surprise that kids are spending a lot of time in front of screens. According to a new study, teens from 8 to 12 years of age spend an average of four­and­a­half hours each day watching TV or using a digital device(数码设备). For teens from 13 to 18, the average is six­and­a­half hours. But those numbers hide a bigger, more complex picture.

    Common Sense Media conducted the study. Here are some truths and some myths (错误看法) that the study revealed(揭示):

    Truth 1: Some teens spend too much time looking at screens.

    Young people are still spending time watching television, especially tweens. One in five tweens uses screen media more than six hours each day, and 18% of teens are looking at their screens for more than 10 hours a day.

    Myth 1: This is the end of reading.

    While the average time young people spend reading, either in print or on a screen, is only 30 minutes per day, kids who took the survey say reading is one of their favorite activities.

    Truth 2: Boys prefer video games; girls prefer social media.

    Among tween boys, 71% enjoy playing video games, twice as many as tween girls. And while more than 25% of teen boys list playing video games as their favorite media activity, only 2% of teen girls do. Teen girls, meanwhile, spend about 40 minutes more each day on social media than boys do.

    Myth 2: The Digital Revolution is making young people more creative than ever. Tweens spend an average(平均)of five minutes and teens nine minutes per day making something creative with all their digital tools, whether it's art, music, or writing.

(1)、From the survey, we can conclude(推断)that      .
A、kids don't like reading any more B、teen boys prefer sports to social media C、kids are becoming much more creative D、more tween girls like video games than teen girls
(2)、The text is mainly developed by        .

(3)、What is the text mainly about?
A、The survey of social media. B、The facts about kids and sports. C、The truth about kids and technology. D、The myth about teens and technology

①As missing children get older,they become quite different from the faces in their last﹣known photographs,which makes finding the really difficult. Now AI(人工智能)can make it easier to match any found children to those old photos. 

②Police can use software(软件)to age photos of missing people,but it seems to work best in adults

③Unlike adults ,the faces of children change greatly as time goes by,and matching photos of found children to old images(画像)(数据库)of missing children is difficult. "Even with a recent face image of a child,it is quite hard for a human to recognize(辨认),who the child is from a large data set of child face images," says Debayan Deb at Michigan State University. 

④Now Deb and his teammates have created an algorithm(算法)to work out the problem. They created a face﹣recognition algorithm on data sets,which have images of nearly 1

⑤AI learned to match recent photographs of children with images taken 2. 5 years earlier. The correct matching rate can be 80 percent. With one year between the two photographs,it was 90 percent correct at recognizing faces. This dropped to 73 percent after three years. The new AI might help to improve accuracy (准确性)of this kind of software

⑥Deb's next goal(目标 )is to make the age gap wider. His team also hopes to develop an app to fight against the sale of children.
