第一部分 语法题型突破篇 专题三 阅读理解 题型二 话题突破 高考命题17 科普知识类 从文章的体裁看,这类文章一般都是说明文,通过对某个自 然现象、某项科学研究、某种最新发现等的详细描述,让大家认 识、了解某方面的科学知识,并学会在生活中运用这种知识。有 时候科普知识类文章的体裁也可能为记叙文,通常叙述与某项发 明或发现相关的人物及事件。 高考热点重温 [高 考 真 题] (2018·天津卷)Give yourself a test.Which way is the wind blowing?How many kinds of wildflowers can be seen from your front door?If your awareness is as sharp as it could be,you'll have no trouble answering these questions. Most of us observed much more as children than we do as adults.A child's day is filled with fascination , newness and wonder.Curiosity gave us all a natural awareness.But distinctions that were sharp to us as children become unclear;we are numb(麻木 的) to new stimulation(刺激),new ideas.Relearning the art of seeing the world around us is quite simple,although it takes practice and requires breaking some bad habits. The first step in awakening senses is to stop predicting what we are going to see and feel before it occurs.This blocks awareness.One chilly night when I was hiking in the Rocky Mountains with some students,I mentioned that we were going to cross a mountain stream.The students began complaining about how cold it would be.We reached the stream,and they unwillingly walked ahead.They were almost knee-deep when they realized it was a hot spring.Later they all admitted they'd felt cold water at first. Another block to awareness is the obsession(痴迷)many of us have with naming things.I saw bird watchers who spotted a bird, immediately looked it up in field guides,and said,a “ruby-crowned kinglet” and checked it off.They no longer paid attention to the bird and never learned what it was doing. The pressures of “time” and “destination” are further blocks to awareness.I encountered many hikers who were headed to a distant camp-ground with just enough time to get there before dark.It seldom occurred to them to wander a bit,to take a moment to see what's around them.I asked them what they'd seen.“Oh,a few birds,” they said.They seemed bent on their destinations. Nature seems to unfold to people who watch and wait.Next time you take a walk,no matter where it is,take in all the sights, sounds and sensations.Wander in this frame of mind and you will open a new dimension to your life. 1.According to Paragraph 2,compared with adults,children are more ____D____. A.anxious to do wonders B.sensitive to others' feelings C.likely to develop unpleasant habits D.eager to explore the world around them 2.What idea does the author convey in Paragraph 3
