36.A 考查上下文理解判断能力.根据上文Whether it is from working on a computer,watching TV,driving or any number of other activities,your eyes can become tired and lose focus可知,视觉疲劳是来自于电脑工作,看电视,驾车还是其它的活动,你的眼睛累了,下文应是:严重的眼疲劳会导致很多其他的病,如近视眼.故选A.
37.D 考查上下文理解判断能力.根据上文Use non-reflective interfaces whenever possible可知,无论什么时候可能的话,使用不反射界面,下文应是:从近到远交替改变你的注意力.故选D
38.C 考查上下文理解判断能力.根据上文If you are at your computer,look out the window for a minute."可知,你如果在看电脑,可以一两分钟不盯着屏幕,下文应是:你可以读纸质的而不是屏幕上看.故选C.
39.G 考查上下文理解判断能力.根据下文Strengthening these muscles with a series of eye exercises will prevent eye strain effectively."可知,用一系列的眼保健操来加强这些肌肉将有效地阻止视觉疲劳,这一段主要介绍:锻炼眼睛.故选G
40.B 考查上下文理解判断能力.根据上文More contrast makes edges easier to recognize so the eyes don't have to focus as much."可知,更多的对比度使边缘更容易识别,因此眼睛不必那么集中,下文应是:但是和周围环境太多的反差会导致视力疲劳.故选B.
点评 七选五题型看似简单,实际上有时完全作对并不容易,需要方法和分析能力及足够的耐力,有必要进行专门练习.首先,快速浏览一遍七个备选答案,先确定哪个选项适合放在文章的什么位置.其次,快速浏览文章,确定文章体裁,抓住文章结构,分析篇章结构,找出各段的主题句或主旨大意.其三,注意各选项中出现的句子衔接手段,寻找句中衔接标志词,七选五备选答案中有两个多余的选项,会对文章中两个空的选择构成干扰,这时要特别细致地比对相似选项.最后,用代入法,检查答案是否合理,将所有选择答案放回空白处,通读全文,检查文章内容是否语义连贯合理、紧扣主题,语篇结构是否通顺连贯、具有一致性、合乎逻辑,写作思路是否清晰明了,格式以及用语是否恰当贴切,从而判断选择的答案是否正确.
