6、f phones. “The use of phones has led to a loss of sleep and face-to-face interactions necessary for their growth,” she said.

11、ellphone a lot, and hold their phones up to their right ears, score worse on one type of memory test. Thats the finding of a new study. That memory impairment might be one side effect of the radiation(放射线) that phones use to keep us connected while were on the go. Nearly 700 Swiss teens took part in

12、 a test of figural memory. This type helps us remember abstract symbols and shapes, explains Milena Foerster. The teens took memory tests twice, one year apart. Each time, they had one minute to remember 13 pairs of abstract shapes. Then they were shown one item from each pair and asked to match it

13、with one of the five choices. The study volunteers also took a test of verbal memory. Thats the ability to remember words. The two memory tests are part of an intelligence test. The researchers also surveyed the teens on how they use cellphones. And they got call records from phone companies. The re

14、searchers used those records to figure out how long the teens were using their phones. This allowed the researchers to work out how big radiation exposure(接触) each person could have got while talking. A phone users exposure to the radiation can differ widely. Some teens talk on their phones more tha

15、n others. People also hold their phones differently. If the phone is close to the ear, more radiation may enter the body, Foerster notes. Even the type of network signal that a phone uses can matter. Much of Switzerland was using an older “second-generation” type of cellphone networks, the study rep

16、orts. Many phone carriers(通信公司) have moved away from such networks. And more companies plan to update their networks within the next few years. The teens scores in the figural memory tests were roughly the same from one year to the next. But those who normally held their phones near the right ears,

17、and who were also exposed to higher levels of radiation, scored a little bit worse after a year. No group of teens showed big changes on the verbal memory test. Why might one type of memory be linked to cellphone use, but not another? Foerster thinks it could have to do with where different memory c

23、的影响,并引入了一些专业人士的观点来支持个人的论证,继而讨论了 学校就学生使用手机问题采取的措施。 1.C细节理解题。根据第一段中的“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会造成多大的问题:焦虑、睡眠 不足等问题。故查维斯的实验目的是证明手机对青少年的影响很大,故选 C项。 2.A推理判断题。根据第二段中的“Chavis is among

24、 a growing number of teachersare now partly to blame for increasing the levels ofOne girl, just during the one hour, got close to 150 Snapchat notifications. 150! she said.”可知,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,其中一部分是智能手机造成的。查 维斯说“一个女孩在一个小时内收到了近 150条 Snapchat的通知。150条!”。由此可 知,Chavis对实验结果感到非常震惊,故选 A 项。 3.

25、D推理判断题。根据第三段中的“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.C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.”以及最后一段讨论的是学校采取的措施可知,接下 来的段落可能会讨论的是一些父母如何处理他们孩子的手机,

26、故选 C项。 B 【文章大意】 本文是一篇说明文。一项新的研究结果表明,用手机打电话的次 数多,并在打电话时把手机举到右耳的青少年在记忆测试中得分更差。这种记忆障碍 可能是手机辐射的副作用之一。 5.C词义猜测题。根据第一段中的“Teenagers who talk on the cellphone a lot, and hold their phones up to their right ears, score worse on one type of memory test.”可知,经 常打电话,并且打电话时把手机举到右耳的青少年,在一项记忆测试中得分更差。由 此可知,经常打电话会有损青

27、少年的记忆力。画线词 impairment和 damage是近义词, 故选 C项。 6.C细节理解题。根据第二段中的“Nearly 700 Swiss teens took part in a test of figural memoryThe teens took memory tests twice, one year apart.(近 700 名瑞士青少年参加 了一项图形记忆测试他们参加了两次测试,间隔一年。)”及“The study volunteers also took a test of verbal memory.(志愿者还接受了语言记忆测试。)”,还有“The two mem

28、ory tests are part of an intelligence test.(这两种记忆测试是智力测试的一部分。)” 可知,青少年们共参加了两种测试,每种测试做两次,共 4 次。由此可知,青少年参加了 两种共 4 次测试,故选 C项。 7.D细节理解题。根据第三段中的“A phone users exposure to the radiation can differ widely. Some teens talk on their phones more than others. People also hold their phones differently. If the p

29、hone is close to the ear, more radiation may enter the body, Foerster notes. Even the type of network signal that a phone uses can matter.”可知,手机用户接触 到的辐射可能会差异很大,打电话多的受辐射大;手机的网络信号类型也至关重要。 由此可知,辐射水平受手机网络类型的影响。故选 D 项。 8.B主旨大意题。根据第一段“Teenagers who talk on the cellphone a lot, and hold their phones up to

30、 their right ears, score worse on one type of memory test. Thats the finding of a new study. That memory impairment might be one side effect of the radiation (放射线) that phones use to keep us connected while were on the go.”可知,一项新研究的 结果表明,经常打电话,并在打电话时把手机举到右耳的青少年在一种记忆测试中得 分更差。这种记忆障碍可能是手机辐射的副作用之一。下文用两种测试数据证明了 这一事实,并对产生这一结果的原因进行了解释。故本文说明了记忆问题与青少年手 机的使用有关。由此可知,B项“Teens cellphone use linked to memory problems(青少 年的记忆问题与手机的使用有关)”为本文最佳标题。
