主题语境:人与社会一一科学与技术本文是说明文。大学生发明智能手杖,不仅能帮助视障人士躲避路上的障碍物,还能提供定位、报警及自卫功能,大大改善了视障人士的生活。28.D。推断。第一段中先通过数据表明全球视障人群数量庞大,继而表明虽然通过使用盲人手杖他们的出行便捷度得到提高,但还是有很多生活困难。言下之意就是,提高视障人群生活满意度的需求迫在眉睫。29.A。理解具体信息。根据第三段中的if any kind of object.making the user aware of theobject coming in front of them可知,如果使用者在行进过程中遇到了任何物体、动物或人,这款智能手杖都会发出提醒。也就是说,这款手杖可以避免使用者在行进途中撞到前方的障碍物。30.A。理解具体信息。根据倒数第二段中的if anyone tries to harm the user,the inbuilt deviceat the bottom of the stick...the blind person to protect themselves可知,手杖尾端的装置可以对侵犯者输出400千伏的电压,这能让视障人士在遇到袭击时保护自己。由此可知,这个装置可以当成一件自卫的武器。31.C。推断。根据最后一段可知,Dutt作为一名学生,心系视障人士的福祉,发明提高其生活便利度的智能手杖。Dut还利用自身的科研优势,为贫困儿童免费提供科研教育。另外,他还在推动妇女安全和自力更生事业方面做出贡献。由此可推知,Dut是一名社会责任感非常强的好青年。D篇主题语境:人与自然一一环境保护本文是说明文。美国人饮食中过多的蛋白质带来了严重的污染。研究人员建议,目前解决该问题的最佳办法是降低蛋白质在饮食中的占比。32.B。推断。第一段提到美国人的饮食对该国的水域造成了不良影响,食物中过多的蛋白质经消化后产生的氮化合物在水域中形成了藻华,污染空气和饮用水。再根据第二段中的Maya Almaraz ..wanted to see how much of this nitrogen entered into the U.S.wastewatersystem because of a protein-heavy diet可知,Almaraz的研究旨在发现美国污水系统中有多少氮是由于这种高蛋白饮食导致的。由此可知,Almaraz的研究聚焦于美国人饮食(对美国污水系统)的影响。33.A。理解具体信息。根据第三段中的Microorganisms that feed on dead algae use up oxygenin the water,leading to "dead zones,"where many species simply cannot survive,in rivers,lakes and oceans可知,以死亡的藻类为食的微生物用光了水中的氧气,造成了“死亡区”,其中的很多物种都无法生存。也就是说,很多生物由于没有赖以生存的氧气,无法存活于这些“死亡区”中。34.D。理解具体信息。根据最后一段中的Although it is possible to treat algal blooms..Someof these methods can even lead to additional pollution可知,现行的藻华治理方式无法根治有害藻类生长,还可能造成二次污染。35.B。理解主旨要义。文章开篇点题,指出美国人高蛋白的饮食惯造成了空气污染和水污染。第二、三段阐释了研究人员对该影响的进一步研究,最后一段指出解决该问题的方法。B项作标题最能概括文意。第二节主题语境:人与自然一一自然生态本文是说明文。文章介绍了生活在沙漠里的几种动物为了适应艰苦的生存环境而进化出来的各种本领。36.B。设空处前一句提到you first look at a desert,B项阐述了看到的结果一一All you see is
