人教版2017高考英语全套解析一轮复习课件：语法精要8 非谓语动词
<p> (3)表示条件 <span word="Watered">Watered</span> <span word="once">once</span> <span word="a">a</span> <span word="day">day</span>，<span word="the">the</span> <span word="flower">flower</span> <span word="will">will</span> <span word="grow">grow</span> <span word="very">very</span> <span word="well">well</span>. 如果每天浇一次水，这花会长得很好。 (4)表示伴随状况 <span word="He">He</span> <span word="stood">stood</span> <span word="there">there</span>，<span word="fascinated">fascinated</span> <span word="by">by</span> <span word="the">the</span> <span word="singing">singing</span>. 他站在那里，被歌声所吸引。 在句子深层结构中，过去分词短语的逻辑主语就是句子的主语。如果过去分词短语的逻辑主语与句子的主语不一致，过去分词短语的逻辑主语则需要用独立结构表达出来，这就是我们通常所说的独立主格结构。如： <span word="The">The</span> <span word="question">question</span> <span word="settled">settled</span>，<span word="they">they</span> <span word="left">left</span> <span word="for">for</span> <span word="home">home</span>. 问题解决了，他们就回家了。</p><p> 1．掌握基本结构，区分三种形式。 非谓语动词有三种：动词不定式、动词的<span word="ing">ing</span>形式和动词的<span word="ed">ed</span>形式。非谓语动词在句中不能作谓语，没有人称和数的变化，但有语态和时态的变化。因此高考备考时，对非谓语动词要有充分的认识和归纳，现在分词表示动作“主动和进行”，过去分词表示“被动和完成”，而不定式则含有“将来”的意义。 解题时，头脑要冷静。一方面要认真分析句子结构，确定所填动词在句子中作谓语还是非谓语；如果作非谓语，还要确定动词与逻辑主语的逻辑关系以及该动作与谓语动词的动作发生时间的先后；同时要注意标点符号特别是逗号的作用。例如：</p><p> (2010·山东潍坊质量抽样)<span word="With">With</span> <span word="trees">trees</span> <span word="and">and</span> <span word="grass">grass</span>________ 39.6%<span word="of">of</span> <span word="the">the</span> <span word="urban">urban</span> <span word="area">area</span>，<span word="the">the</span> <span word="city">city</span> <span word="of">of</span> <span word="Weifang">Weifang</span> <span word="has">has</span> <span word="taken">taken</span> <span word="on">on</span> <span word="a">a</span> <span word="new">new</span> <span word="look">look</span>. <span word="A">A</span>．<span word="coveredB">coveredB</span>．<span word="covering">covering</span> <span word="C">C</span>．<span word="to">to</span> <span word="be">be</span> <span word="covered">covered</span></p>
