gre阅读长难句实例分析55
<p> 以下是<span word="gre">gre</span>阅读长难句实例分析。<span word="gre">gre</span>长难句一直都是考生比较头疼的一个问题，不是因为<span word="gre">gre</span>考试专门考察这部分，而是在<span word="gre">gre</span>阅读中需要明白这些长难句才能理解整篇文章的意思。</p><p> <span word="In">In</span> <span word="order">order</span> <span word="to">to</span> <span word="understand">understand</span> <span word="the">the</span> <span word="nature">nature</span> <span word="of">of</span> <span word="the">the</span> <span word="ecologists">ecologists</span> <span word="investigation">investigation</span>，<span word="we">we</span> <span word="may">may</span> <span word="think">think</span> <span word="of">of</span> <span word="the">the</span> <span word="density">density</span>-<span word="dependent">dependent</span> <span word="effects">effects</span> <span word="on">on</span> <span word="growth">growth</span> <span word="parameters">parameters</span> <span word="as">as</span> <span word="the">the</span> <span word="signal">signal</span> <span word="ecologists">ecologists</span> <span word="are">are</span> <span word="trying">trying</span> <span word="to">to</span> <span word="isolate">isolate</span> <span word="and">and</span> <span word="interpret">interpret</span>，<span word="one">one</span> <span word="that">that</span> <span word="tends">tends</span> <span word="to">to</span> <span word="make">make</span> <span word="the">the</span> <span word="population">population</span> <span word="increase">increase</span> <span word="from">from</span> <span word="relatively">relatively</span> <span word="low">low</span> <span word="values">values</span> <span word="or">or</span> <span word="decrease">decrease</span> <span word="from">from</span> <span word="relatively">relatively</span> <span word="high">high</span> <span word="ones">ones</span>，<span word="while">while</span> <span word="the">the</span> <span word="density">density</span>-<span word="independent">independent</span> <span word="effects">effects</span> <span word="act">act</span> <span word="to">to</span> <span word="produce">produce</span> <span word="noise">noise</span> <span word="in">in</span> <span word="the">the</span> <span word="population">population</span> <span word="dynamics">dynamics</span>.</p><p> 为了能理解生态学家们所从事的研究的性质，我们可以把那些作用于增长参数的密度依赖效应视作生态学家们力图将其分离并予以解释的信号，正是这一信号倾向于使种群从相对较低的数值递增，或从相对较高的数值递减;而与此同时，那些密度独立效应起到的作用则构成了种群动态变化中的噪音。</p><p> 难句类型：复杂修饰、插入语、省略</p><p> 解释：句子不仅很长，而且有两个地方看上去不舒服，第一：<span word="think">think</span> <span word="of">of</span> ..<span word="as">as</span>不是很常见，其实<span word="think">think</span> <span word="of">of</span> 这个词组就等于<span word="consider">consider</span>,<span word="imagine">imagine</span>,加上后面的<span word="as">as</span>就是把.认为是的意思。第二个不习惯的地方是<span word="signal">signal</span>后面的大段修饰语，不但长度很长，而且在<span word="signal">signal</span>后面还省略了一个<span word="that">that</span>，正常应该是<span word="the">the</span> <span word="signal">signal</span> <span word="that">that</span> <span word="ecologists">ecologists</span> <span word="are">are</span> <span word="trying">trying</span> <span word="to">to</span> <span word="isolate">isolate</span> <span word="and">and</span> <span word="interpret">interpret</span>,,与前面见过对<span word="that">that</span>的省略不同的是，这次<span word="that">that</span>在句中不是句子的宾语，而是不定式动词的宾语。</p>
