2017届高考英语一轮复习写作指导课件：基本句型的扩展 1（新人教版）
<p> 前面所讲英语的六种基本句型只是英语句子的最基本框架，要表达千差万别、丰富多彩的思想内容，仅仅依靠这样几个简单的句子框架显然是不够的。如果我们以这些基本句型为基础，对句子加以扩展，就可以增大信息量, 使句子表达手段得更加丰富，从而满足我们对各种复杂内容表达的需要。</p><p> 英语句型扩展的手段主要有三种：(1)增加并列成分；(2)增加修饰成分；(3)使用各类从句。</p><p> 基本句型的扩展(Ⅰ)</p><p> 增加并列成分</p><p> 英语句子中的任何一个成分都可以增加一个或多个并列成分，从而使句子变得长而复杂。例如：</p><p> <span word="John">John</span> <span word="visited">visited</span> <span word="a">a</span> <span word="farm">farm</span>.</p><p> 这是一个典型的<span word="SVO">SVO</span>(主谓宾) 句型，通过增加并列成分可扩展为：</p><p> <span word="John">John</span>, <span word="Mike">Mike</span> <span word="and">and</span> <span word="their">their</span> <span word="classmates">classmates</span> <span word="went">went</span> <span word="to">to</span> <span word="the">the</span> <span word="countryside">countryside</span> <span word="and">and</span> <span word="visited">visited</span> <span word="a">a</span> <span word="farm">farm</span> <span word="and">and</span> <span word="a">a</span> <span word="nursing">nursing</span> <span word="home">home</span>.</p><p> 句中<span word="Mike">Mike</span> <span word="and">and</span> <span word="their">their</span> <span word="classmates">classmates</span> 是<span word="John">John</span>的并列主语，<span word="went">went</span> <span word="to">to</span> <span word="the">the</span> <span word="countryside">countryside</span> 是<span word="visited">visited</span>的并列谓语，<span word="a">a</span> <span word="nursing">nursing</span> <span word="home">home</span>是<span word="a">a</span> <span word="farm">farm</span>的并列宾语。 并列的成分也可以是句子，构成并列句。即：简单句+并列连词+简单句</p><p> 如：<span word="I">I</span> <span word="help">help</span> <span word="her">her</span> <span word="and">and</span> <span word="she">she</span> <span word="helps">helps</span> <span word="me">me</span> . 我帮助她，她帮助我。[简单句（主+谓+宾）+并列连词<span word="and">and</span>+简单句（主+谓+宾）]</p><p> <span word="I">I</span> <span word="bought">bought</span> <span word="her">her</span> <span word="a">a</span> <span word="birthday">birthday</span> <span word="present">present</span> <span word="but">but</span> <span word="she">she</span> <span word="doesn">doesn</span>’<span word="t">t</span> <span word="like">like</span> <span word="it">it</span> . 我给她买了份生日礼物但她不喜欢。 [简单句（主+谓+宾+宾补）+并列连词<span word="but">but</span>+简单句（主+谓+宾）]</p>
