二、现代文阅读 科技说明文阅读 别让智能手机出卖你 杨洋 ①央视“3·15晚会”上发布的《三号消费预警》,让“信息安全”这一话题成 为大众关注的焦点。
②目前,使用智能手机的人,有一半以上都选择了ROOT或者越狱,两者都是获得设备的最高使用权限的意思,只是安卓和iOS系统的叫法不一样罢了。
最高使用权限的意思,就是可以任意安装未经认证的第三方程序,自主启用或禁用任一进程以及硬件,甚至有权修改系统的参数和文件。
但凡ROOT或越狱成功,如果有不法分子侵入了用户的手机,轻则用户隐私不保,重则手机变砖。
③如今,大家都已经习惯了使用二维码,它既可以是文本信息,也可以是网络连接。
无须键盘输入,只需要用摄像头扫一扫,或是图片直接识别,便可轻轻松松地获取信息。
但这块“风水宝地”也已经被不法分子锁定,用户通过扫描二维码打开的很有可能是钓鱼网站或者木马程序。
④还有一点需要特别提醒的是,用户在使用智能手机的过程中,要认真对待每次出现的提示。
很多时候一次跳出多个提示,如果用户不留意内容,就容易都点“允许”了。
有些“允许”的协议说不定就是一张“卖身契”,什么通讯录、账户信息都允许获取,个人隐私就这么在不知不觉中泄露出去了。
⑤相信大家对于微信诈骗已经见怪不怪了,例如“摇一摇”“附近的人”等功能,都可能让手机用户成为诈骗或者骚扰的对象。
为了避免此种使用风险,用户可以点击“设置-通用-功能-附近的人”,选择“清空并停用”。
此外,用户还要在微信“设置-隐私”选项中关闭“通过QQ好友搜索到我”“可通过手机号搜索到我”和“允许陌生人查看十张照片”等功能,以绝后患。
⑥还需要注意的是,现在通过手机订购商品需要确定用户的位置信息,以便更好地为用户服务,而获取用户的所在地址信息,往往通过“GPS定位”。
而这些定位服务,恰恰为一些O2O(OnlineToOffline,即线上到线下)的不法分子开辟了绿色通道。
苹果手机在iOS7系统中,加入了“常去地点”功能,可以在地图上显示用户曾到过的所有位置。
该数据如果被他人知道,后果真的不堪设想。
因此,为了安全起见,还是关闭这些功能为好!用户可以通过“设置-隐私-定位服务-系统服务-常去地点”来关闭该功能。
⑦如果用户需要变卖自己的旧手机,那么最好对手机进行初始化和格式化,并用电影、音乐等塞满手机储存卡,这样就可以保证用户的隐私信息不外泄了。
⑧可能有人觉得,要记住那些林林总总的设置、操作实在太麻烦了,如果能安装个手机安全类的APP,就什么都不必费心了,何乐不为呢!话虽没错,但是使用的时候,还是需要用户多长个心眼儿,因为APP也有“马失前蹄”的时候。
欧洲著名的安全软件——熊猫卫士(PandaSecurity)就在某次更新中,因为一个文件签名的小小错误,把自己的核心文件标记成了恶意程序并进行了隔离,于是整个软件都不好了。
不管怎么说,小心使得万年船嘛! 1.下列说法与文章内容不相符合的一项是( ) A.使用智能手机的用户获得设备的最高使用权限后,就可以任意安装未经认证的笫三方程序,自主启用或禁用任一进程以及硬件,甚至有权修改系统的参数和文件。
最严重的后果是用户的隐私将不保。
B.已被不法分子锁定的“风水宝地”——二维码,它既可以是文本信息,也可以是网络链接。
用户扫描二维码打开的很有可能是钓鱼网站或者木马程序。
C.用户使用的手机不论ROOT或越狱与否,所有提示不假思索都“允许”,将会使用户的通讯录信息、账户信息等个人隐私在不知不觉中泄露出去。
D.苹果手机1057系统中,“常去地点”这一功能可以在地图上显示用户曾到过的所有位置。
该数据对普通用户毫无意义,伹一旦被警察或不法分子获取,后果将不堪设想。
2.下列对选文内容的理解与分析正确的一项是( ) A.文章告诉所有手机用户,只要安装一个手机安全类的APP,就可以放心大胆地使用智能手机了。
B.选文第③段主要运用了举例子和作诠释的说明方法,说明了使用二维码是有风险的,所以只要是二维码,绝不要扫描。
C.选文④-⑧段运用逻辑顺序说明了使用智能手机时的几个注意事项。
D.选文笫②段加点的词语“目前”可以删去,笫⑤、⑥段中的“可能”、“一些”是不能删去的,删去后内容与实际情况不符,这都体现了说明文语言的准确性。
3.结合原文分析,相比较而言,以下哪种做法被智能手机“出卖”的风险较大? A.用户一般不要轻易把手机ROOT或越狱,要养成平时关闭“常去地点"等有安全隐患功能的习惯。
B.—定要认真对待每一个提示,特別是短信、微信、QQ等里面出现的不明链接更是不要轻易打开。
C.为了避免微信在使用“摇一摇”、“附近的人”等功能所带来的危险,手机用户尽量少使用这些功能。
D.旧手机变卖时,一定要对手机进行初始化和格式化,并用电影或音乐等塞满手机内储存卡。
如手机有外置储存卡必须取出,不卖给回收商。

The British International Education Association hosted a conference in January to _______ the importance of technological solutions in protecting vulnerable (易受伤害的) species and ecosystems.Speakers underlined how technology can help _______: drones can circle high above the ocean to spot whales, while certain cameras can identify members of an individual species. According to Claudio Sillero, biology professor at Oxford University, technology is changing how preservation research is done — but it’s in a(n) _______ way.As technology gets better and cheaper, researchers become better at doing what they were already doing._______, remote sensing used to be a very technical tool but is now widespread, and everyone uses global positioning system (GPS) for surveying. But teaching preservation and ecology courses in university _______.Some teach drone surveying methods in depth while others don’t even mention them.“The fact is, using drones is quite a(n) _______ to the interdisciplinary (跨学科的) ‘unknown’ of engineering, and potentially an area where lecturers may not feel confident to teach yet,” Serge Wich, an expert in primate biology says.“Students are taught about _______ technologies such as automatic sound recorders, but drones are often missing from university teaching.Consequently, drone use among researchers is still fairly ________ and focused on getting photos.” Wich’s team of researchers used techniques to develop a fully automated drone technology system that ________ and monitors the health of endangered animals globally.It’s designed to be cheap, stable and simple to use, so that local communities in developing countries can operate it ________ without technical background.Yet it’s not more widely used on the grounds of researchers’ lack of skills to use this technology.In biology, where drones are used, few can program an algorithm (算法) specifically for their preservation or research problem.“There’s much that needs to be done to ________ those two worlds and to make AI more user-friendly so that people who can’t program can still use the technology,” Wich says. ________, the sad truth is that better technology alone will not save any more species from dying out, Greengrass warns.“As human populations increase, so do threats and pressure on wild places.Preservationists are ________ for not doing enough but it’s often an issue of people, conflict and governance.” Technology may help provide far greater knowledge, but governments still need to act. 1.A.shortageB.threatsC.potentialD.responsibilities 2.A.researchersB.authoritiesC.opponentsD.professionals 3.A.highlightB.overlookC.assessD.calculate 4.A.educationB.preparationC.preservationD.distinction 5.A.evolutionaryB.flexibleC.virtualD.dramatic 6.A.As a resultB.In conclusionC.On the contraryD.For example 7.A.differsB.equalsC.multipliesD.struggles 8.A.obstacleB.leapC.equivalentD.exception 9.A.ill-intentionedB.fully-preparedC.well-establishedD.narrowly-applied 10.A.definiteB.vagueC.simpleD.limited 11.A.controlsB.tracksC.supervisesD.improves 12.A.earnestlyB.independentlyC.secretlyD.impersonally 13.A.bridgeB.fixC.dismissD.grasp 14.A.ThereforeB.MoreoverC.HoweverD.Otherwise 15.A.firedB.insultedC.qualifiedD.criticized 六、阅读理解 A Different Kind of Spring Break For many American university students, the week-long spring break holiday means an endless part on a sunny beach in Florida or Mexico.In Panama City Beach, Florida, a city with a permanent population of approximately 36,000, more than half a million university students arrive during the month of March to play and party, making it the number one spring break destination in the United States. A week-long drinking binge is not for everyone, however, and a growing number of American university students have found a way to make spring break matter.For them, joining or leading a group of volunteers to travel locally or internationally and work to address problems such as poverty, homelessness, or environmental damage makes spring break a unique learning experience that university students can feel good at. During one spring break week, students at James Madison University in Virginia participated in 15 “alternative spring break” trips to nearby states, three others to more distant parts of the United States, and five international trips.One group of JMU students traveled to Bogalusa, Louisiana, to help rebuild homes damaged by Hurricane Katrina.Another group traveled to Mississippi to organize creative activities for children living in a homeless shelter.One group of students did go to Florida, but not to lie on the sand.They performed exhausting physical labor such as maintaining roving invasive plant species that threaten the native Florida ecosystem. Students who participate in alternative spring break projects find them very rewarding.While most university students have to get their degrees before they can start helping people, student volunteers are able to help people now.On the other hand, the accommodations are far from glamorous.Students often sleep on the floor of a school or church, or spend the week camping in tents.But students only pay around $250 for meals and transportation, which is much less than some of their peers spend to travel to more traditional spring break hot spot. 1.How many university students travel to Panama Beach City every March for spring break? A.Around 36,000.B.Around 50,000. C.Around 500,000.D.Around 10,000. 2.The underlined word “binge” in paragraph 2 probably means ______. A.doing too much of somethingB.studying for too long C.refusing to do somethingD.having very little alcohol 3.Which of the following gives the main idea of the third paragraph? A.One group of JMU students worked on homes damaged by a hurricane. B.Children living in homeless shelters enjoy creative activities. C.Some students work to help the environment on alternative spring break trips. D.University students do different types of work on alternative spring break trips. 4.What is implied in this article is that ______. A.university students spend more than $250 for traditional spring break trips B.university students complain about the accommodations on alternative spring break trips C.university students may take fewer alternative spring break trips in the future D.university students would prefer to wait until they have their degrees to start helping people Cropping (修剪) an Image With the Snap Shot Program Welcome to the world of photo-editing! Cropping an image allows you to zero in on (对准,聚焦) just the portion that is important to your project.For example, you may want to an image of a covered train in a report but may not want to include the whole train.Cropping the image allows you to select only the small area you wish to retain (保留) and eliminate all other portions of the original picture.
