Text 2 A study published in the International Journal of Business Administration found that what students read in college directly effects the level of writing they achieve.In fact,researchers found that reading content and frequency may exert more significant impacts on students'writing ability than writing instruction and writing frequency.Students who read academic journals,literary fiction,or general nonfiction wrote with greater svntactic SODhistication（more comDlex sentences）than those who read genre fiction（mysteries,fantasy,or science fiction）or exclusively web-based aggregators.The highest scores went to those who read academic journals;the lowest scores went to those who relied sotely on web-based content.Recent research also revealed that"deep reading"-defined as reading that is slow,immersive,rich in sensory detail and emotional and moral complexity-is distinctive from light reading-little more than the decoding of words.Deep reading occurs when the language is rich in detail,allusion,and metaphor,and taps into the same brain regions that would activate if the reader were experiencing the event.Deep reading is great exercise for the brain and has been shown to increase empathy,as the reader dives deeper and adds reflection,analysis,and personal subtext to what is being read.It also offers writers a way to appreciate all the qualities that make novels fascinating and meaningful-and to tap into his abllity to write on a deeper level.Light reading is equated to what one might read in online blogs,or"headline news"or"entertainment news"websites,particularly those that breezily rely on lists or punchy headlines,and even occasionally use emojis to communicate.These types of light reading lack a genuine voice,a viewpoint,or the sort of analyses that might stimulate thought.It's light and breezy reading that you can skim through and will likely forget within minutes.Deep reading activates our brain's centers for speech,vision,and hearing,all of which work together to help us speak,read,and write.Reading and writing engages Broca's area,which enables us to perceive rhythm and syntax;Wernicke's area,which impacts our perception of words and meaning;and the angular gyrus,which is central to perception and use oflanguage.These areas are wired together by a band of fibres,and this interconnectivity likely helps writers mimic and synchronize language and rhythms they encounter while reading.Your reading brain senses a cadence that accompanies more complex writing,which your brain then seeks to emulate when writing.Students'writing abilities are mostly infiuenced by_____A.writing frequencies of studentsB.writing instructions from teachersC.students'reading contentD.teachers'scores and evaluations
