中考冲刺英语专练第六讲
<p> 【第6讲：不定式】</p><p> 不定式和动词象一对姐妹一样亲密，本不该拆开来讲，可是篇幅有限，只能让他们分开了。不定式的构成非常简单，是<span word="to">to</span>+动词原形。当然，<span word="to">to</span>有时也可以不带。动词不定式没有人称和数的变化，可以担当除谓语外的任何句子成分。那什么时候可以不带<span word="to">to</span>呢 <span word="Listen">Listen</span> <span word="to">to</span> <span word="me">me</span> <span word="carefully">carefully</span>.</p><p> 不定式省<span word="to">to</span>有四种情况：</p><p> 使役动词 <span word="let">let</span>,<span word="have">have</span>,<span word="make">make</span> 等后接不定式。如：<span word="Let">Let</span> <span word="him">him</span> <span word="go">go</span>! 让他走!</p><p> <span word="would">would</span> <span word="rather">rather</span>，<span word="had">had</span> <span word="better">better</span>后。如：<span word="You">You</span> <span word="had">had</span> <span word="better">better</span> <span word="stay">stay</span> <span word="at">at</span> <span word="home">home</span>.你最好呆在家里。</p><p> <span word="Why">Why</span>... / <span word="why">why</span> <span word="not">not</span>...后。如：<span word="Why">Why</span> <span word="not">not</span> <span word="have">have</span> <span word="a">a</span> <span word="good">good</span> <span word="rest">rest</span> <span word="on">on</span> <span word="Sunday">Sunday</span> 为什么星期天不好好休息一下呢 </p><p> 感官动词 <span word="see">see</span>, <span word="watch">watch</span>, <span word="look">look</span> <span word="at">at</span>, <span word="hear">hear</span>, <span word="listen">listen</span> <span word="to">to</span>, <span word="smell">smell</span>,<span word="feel">feel</span>, <span word="find">find</span> 等后作宾补，省<span word="to">to</span>。如：<span word="I">I</span> <span word="saw">saw</span> <span word="him">him</span> <span word="dance">dance</span>. 我看见他跳舞。</p><p> 注意：这些情况在被动句中可千万不可省<span word="to">to</span> 哟！ 如：<span word="The">The</span> <span word="boss">boss</span> <span word="made">made</span> <span word="them">them</span> <span word="work">work</span> <span word="the">the</span> <span word="whole">whole</span> <span word="night">night</span>. 变成被动句：<span word="They">They</span> <span word="were">were</span> <span word="made">made</span> <span word="to">to</span> <span word="work">work</span> <span word="the">the</span> <span word="whole">whole</span> <span word="night">night</span>.</p><p> 不定式的特殊用法：</p><p> <span word="It">It</span>与不定式：动词不定式可以做主语，但如果动词不定式太长，显得头重脚轻的，那么我们就可用形式主语<span word="it">it</span>代替，而把真正主语(即不定式)放于句尾。</p><p> 如: <span word="It">It</span> <span word="is">is</span> <span word="not">not</span> <span word="difficult">difficult</span> <span word="for">for</span> <span word="me">me</span> <span word="to">to</span> <span word="study">study</span> <span word="English">English</span> <span word="well">well</span>.(对我来说学好英语是可能的。)</p>
