2017届高考英语考前冲刺：强化非谓语动词
<p> 2017届高考英语考前冲刺专题强化非谓语动词</p><p> 一、动词不定式作主语</p><p> 不定式短语作主语时，如果主语较长，往往在句首用<span word="it">it</span>作形式主语，而将真正的主语(不定式)移到谓语动词之后，形成“<span word="it">it</span>＋谓语＋(作主语的)不定式”结构，以避免头重脚轻，保持句子结构的平衡。</p><p> [典例1] <span word="It">It</span> <span word="is">is</span> <span word="my">my</span> <span word="honor">honor</span> ________<span word="here">here</span> <span word="to">to</span> <span word="spend">spend</span> <span word="some">some</span> <span word="time">time</span> <span word="with">with</span> <span word="you">you</span>.</p><p> <span word="A">A</span>．<span word="to">to</span> <span word="be">be</span> <span word="invited">invited</span></p><p> <span word="B">B</span>．<span word="inviting">inviting</span></p><p> <span word="C">C</span>．<span word="being">being</span> <span word="invited">invited</span></p><p> <span word="D">D</span>．<span word="to">to</span> <span word="invite">invite</span></p><p> [解析] 此处表示具体的某一次动作，应用不定式结构，故排除<span word="B">B</span>、<span word="C">C</span>。根据逻辑关系可知，“我”是“被邀请”，因此用动词不定式的被动式。故选<span word="A">A</span>。此时前面的<span word="It">It</span>只是形式主语，后面的不定式才是真正的主语。</p><p> [答案] <span word="A">A</span></p><p> 二、动词不定式作表语</p><p> 动词不定式可作表语，通常说明或解释主语的内容，也可表示将来的动作。</p><p> [典例2] <span word="The">The</span> <span word="purpose">purpose</span> <span word="of">of</span> <span word="new">new</span> <span word="technology">technology</span> <span word="is">is</span> <span word="to">to</span> <span word="make">make</span> <span word="life">life</span> <span word="easier">easier</span>，________<span word="it">it</span> <span word="more">more</span> <span word="difficult">difficult</span>.</p><p> <span word="A">A</span>．<span word="not">not</span> <span word="making">making</span></p><p> <span word="B">B</span>．<span word="not">not</span> <span word="make">make</span></p><p> <span word="C">C</span>．<span word="not">not</span> <span word="to">to</span> <span word="make">make</span></p><p> <span word="D">D</span>．<span word="to">to</span> <span word="not">not</span> <span word="make">make</span></p><p> [解析] 前面用动词不定式作表语说明新技术的目的，后面用不定式的否定式作表语，进一步说明新技术的作用。不定式的否定形式是在不定式的标志词<span word="to">to</span>前加<span word="not">not</span>。故答案为<span word="C">C</span>。</p>
