your GPS CNN We re nearing the peak of the 11 year solar cycle so double check your GPS and watch where you re going On Thursday the sun unleashed a massive solar flare Solar flares can disrupt radio communications including devices that use Global Positioning System technology such as cell phones airplanes and car navigation systems So if you re relying on your GPS for driving directions to find your location on your phone s mapping tool or for any other purpose have a backup navigation system handy such as a printed map Even more important pay close attention to where you are and where you re going Don t rely solely on your GPS to give you directions In 2006 research from Cornell University proved that solar flares can cause GPS devices to lose signal This can cause these devices to temporarily misrepresent your location or otherwise malfunction If you re driving to the beach using your car s navigation system you ll be OK If you re on a commercial airplane in zero visibility weather maybe not said Paul Kintner head of Cornell s GPS Laboratory In addition solar flares can disrupt power systems This week National Geographic reported Under the right conditions solar storms can create extra electrical currents in Earth s magnetosphere the region around the planet controlled by our magnetic field The electrical power grid is particularly vulnerable to these extra currents which can infiltrate 渗透 high voltage transmission lines causing transformers to overheat and possibly burn out This week s flare called a coronal mass ejection registered M9 3 on the Richter scale of flares about the highest level in the medium category Larger flares that fall into the X category can cause global radio blackouts but large M class flares also can cause radio disruptions This is one of a series of recent bouts of severe space weather as the solar cycle approaches solar maximum in 2013 Other major flares came in February and June and more may follow 1 Which is the least affected by solar flare A Communications of the internet B Airplanes navigation systems C Car navigation systems D Communications of cell phones 2 What can help you better if massive solar flare break out A The phone s mapping tool B Global Positioning System C The map on car navigation systems D The printed map 3 The underlined word malfunction refers to A succeed to run properly B fail to run properly C get along well D carry on smoothly 4 According to fourth paragraph what department should prepare for the bad effect of solar flares A The GPS producer B The car producer C The power company D The traveling company 5 How many times the major solar flare has broken out till the report was released A Only one B Twice C Three times D Four times 答案解析 本文是一篇科普文章 介绍了最近的太阳耀斑可能会干扰你的 GPS 1 A 细节推断题 根据第一段第二句可知 太阳耀斑能够干扰到无线电通讯 包括使用全球定位系统技术 的设备 如手机 飞机和交通导航系统 故正确答案为 A 2 D 细节推断题 根据文章第二段第一句后半部分 have a backup navigation system handy such as a printed map 可知 那就在手头准备一个备份导航系统吧 如打印地图 故正确答案为 D 3 B 猜测词意题 根据前文 This can cause these devices to temporarily misrepresent your location 可知这会导致 这些设备暂时误报你的位置 故根据文章结构可知划线部分与 misrepresent your location 同义 由此可断定 该单词意思为 失灵或发生故障 故正确答案为 B 4 C 综合推断题 第四段谈到 太阳耀斑会干扰电力系统 本周国家地理报道 在合适的条件下 太阳 耀斑会地球磁层 地球周围受磁场控制的区域 产生额外电流 相对于这些电流而言 电网极其脆弱 这些电流混入高压传输线引起变压器过热且可能烧毁 由此断定电力公司必须对此类问题作出反应 5 C 综合推断题 根据文章结尾可知 这是最近一系列恶劣空间天气之一 因为太阳活动周期接近 2013 的 太阳最活跃期 其他大的耀斑已经在 2 月和 6 月份出现过 由此可以断定截止本报道发布时 大的耀斑共出 现过三次 故正确答案为 C 2 If you struggled through high school algebra you probably thought you simply weren t born good at math You might have been right at least according to a new study by Johns Hopkins University psychologists that suggests that math ability is linked to your inborn number sense Also known as approximate number system number sense is inherent in all animals including humans It s what we use to instantly estimate how many people are in a meeting or how many free seats are in a movie theater Animals use it to figure out where the most plants or game are and to track how much food they ve gathered Now scientists have measured number sense in preschoolers who are too young to have received any formal math education and linked it to performance of tests of math ability The relationship between number sense and math ability is important and intriguing because we believe that number sense is universal whereas math ability has been thought to be highly dependent on culture and language and takes many years to learn said study author Melissa Libertus in a statement Past research has associated number sense with math ability in older children but the Libertus and her team s study involved 200 younger children with an average age of 4 The children were given number sense test that involved viewing groups of blue and yellow dots on a computer screen and estimating which color group had more dots Each child then took math ability tests consisting of numbering skills numeral literacy calculation skills and other abilities Kids who did better at estimating the dots in the first test also did better at the math tests the researchers found suggesting that at least some math ability may be linked to one s inborn number sense The study authors also gave the kids tests of general intelligence to rule out the possibility that those who did better on the math tests were simply those who performed well on all tests 1 According to the passage number sense is mainly A developed in primary school B inherited from parents C evolved in nature D developed in high school 2 Scientists usually consider math ability A takes short time to learn B lowly depends on culture C lowly depends on language D mainly rely on language and culture 3 How many kind of skills did Libertus test the children A Only one skill B Two skills C Three skills D At least four 4 The underlined phrase rule out in the fourth paragraph refers to A get rid of B consist of C connect with D spread out 5 What s the main idea of the passage A Help kids achieve greater heights in math B Kids number sense mainly relies on teaching C People may be born good or bad at math D Math ability has nothing to do with number sense 答案解析 本文是一篇科普文章 文章介绍了根据研究表明 数学能力或与生俱来 1 B 细节了解题
