Question

    High school biology teacher Kelly Chavis knew smartphones were a problem in her class. But not even the students realized how much of a problem the devices were until Chavis did an in-class experiment.

For one class period, students used a whiteboard to count every Snapchat, Instagram, text, call that appeared on their phones. Chavis is among a growing number of teachers, parents and health experts who believe that smartphones are now partly to blame for increasing the levels of student anxiety. “One girl, just during the one hour, got close to 150 Snapchat notifications. 150!” she said.

Jean Twenge, a psychology professor at San Diego State University in California, said it is not a coincidence that youth mental health issues have risen with the number of phones. “This use of phones has led to a loss of sleep and face-to-face interactions necessary for their growth,” she said.

Researchers are still not sure whether phones cause student depression or depression causes phone use. But nearly 60 percent of parents said they worry about the influence of social media on their child’s physical and mental health.

Both schools and parents are starting to take steps to deal with the problem. Many public schools pay outside companies to watch students’ social media activity for signs of anxiety. Other schools invite in yoga teachers and comfort dogs to help calm students.

1.What’s the purpose of Chavis’s experiment?

A.To see how many students have smartphones.

B.To find out how popular her students are.

C.To show smartphones influence teenagers greatly.

D.To tell her students how to use smartphones wisely.

2.How did Kelly Chavis feel about the result?

A.Shocked. B.Excited. C.Satisfied. D.Frightened.

3.Which of the following is true according to Jean Twenge?

A.Students are now under great stress.

B.Students spend too much money on smartphones.

C.Over-using phones cause drops in students’ grades.

D.Over-using phones may harm students’ body and mind.

4.What might be talked about if the passage is continued?

A.How other schools deal with students’ phones.

C.How some parents deal with their children’s phones.

D.Whether students are willing to give up using phones.

【解析】

这是一篇议论文。作者通过Kelly Chavis的课堂实验展示了智能手机对学生的影响，并引一些专业人士的观点来支持个人的论证，继而说明了学校就学生使用手机问题采取的措施。

1.细节理解题。根据第一段的But not even the students realized how much of a problem the devices were until Chavis did an in-class experiment.和下文可知，直到查维斯在课堂上做了一个实验，学生们才意识到这些设备有多大的问题：焦虑、睡眠不足等问题，故查维斯的实验目的是想去展示手机对青少年的影响很大，故选C项。

2.推理判断题。根据第二段的Chavis is among a growing number of teachers…are now partly to blame for increasing the levels of…“One girl, just during the one hour, got close to 150 Snapchat notifications. 150!” she said.越来越多的老师、家长和健康专家认为，学生的焦虑程度越来越高，部分原因是智能手机造成的，查维斯就是其中之一。“一个女孩在一个小时内收到了近150条Snapchat通知。150条!”，可知Chavis对于实验的结果是非常震惊的，故选A项。

3.推理判断题。根据第三段的it is not a coincidence that youth mental health issues have risen with the number of phones.可知Jean Twenge认为过度使用手机可能会伤害学生的身心。故选D项。

4.推理判断题。根据最后一段的第一句Both schools and parents are starting to take steps to deal with the problem.可知最后一段讨论的是学校应采取的措施，那么接下来的段落可能会讨论的问题是一些父母如何处理他们孩子的手机。故选C项。
