高考英语二轮复习精品课件：专题二语法 第5讲名词性从句（大纲版湖北专用）
<p> 语 法 第5讲</p><p> 名词性从句</p><p> 在复合句中起名词作用的从句叫做名词性从句。名词性从句包括主语从句、宾语从句、表语从句和同位语从句。名词性从句一直是高考的重要考点之一。 一、名词性从句的引导词 <span word="that">that</span> 与 <span word="what">what</span> 的区别</p><p> <span word="that">that</span> 在从句中不充当句子成分，只起连接作用；而 <span word="what">what</span> 不仅起连接作用，而且也可充当句子成分。</p><p> <span word="What">What</span> <span word="we">we</span> <span word="can">can</span>’<span word="t">t</span> <span word="get">get</span> <span word="seems">seems</span> <span word="better">better</span> <span word="than">than</span> <span word="what">what</span> <span word="we">we</span> <span word="have">have</span>.</p><p> 句中有主语从句和宾语从句，<span word="what">what</span> 在这两个名词性从句中都作宾语。</p><p> <span word="It">It</span> <span word="worried">worried</span> <span word="her">her</span> <span word="a">a</span> <span word="bit">bit</span> <span word="that">that</span> <span word="her">her</span> <span word="hair">hair</span> <span word="was">was</span> <span word="turning">turning</span> <span word="grey">grey</span>.=<span word="That">That</span> <span word="her">her</span> <span word="hair">hair</span> <span word="was">was</span> <span word="turning">turning</span> <span word="grey">grey</span> <span word="worried">worried</span> <span word="her">her</span> <span word="a">a</span> <span word="bit">bit</span>.</p><p> 第一句中句首的先行词 <span word="It">It</span> 作形式主语，真正的主语是后面的从句。<span word="that">that</span> 在主语从句中不充当句子成分， 只起连接作用。 二、名词性从句中的<span word="it">it</span> 作形式主语或形式宾语</p><p> 在名词性从句中为了保持句子的平衡，往往用 <span word="it">it</span> 作形式主语或形式宾语，而把真正的主语或宾语放到后面。 <span word="It">It</span> <span word="is">is</span> <span word="a">a</span> <span word="fact">fact</span> <span word="that">that</span> <span word="English">English</span> <span word="is">is</span> <span word="being">being</span> <span word="accepted">accepted</span> <span word="as">as</span> <span word="an">an</span> <span word="international">international</span> <span word="language">language</span>. =<span word="That">That</span> <span word="English">English</span> <span word="is">is</span> <span word="being">being</span> <span word="accepted">accepted</span> <span word="as">as</span> <span word="an">an</span> <span word="international">international</span> <span word="language">language</span> <span word="is">is</span> <span word="a">a</span> <span word="fact">fact</span>. 三、名词性从句的语序</p><p> 在名词性从句中，关联词要提到句首，句子用陈述句语序。当关联词含有疑问的意义时，考生受习惯影响往往会错误地使用疑问句语序。克服这种错误的关键是要找准从句中的主语和谓语。</p>
