中考冲刺英语专练第五讲
<p> 【第5讲：动词】</p><p> 我们步步深入,开始接触到整个句子的<span word="heart">heart</span>--动词了。掌握了动词，你学起英语来就会感到驾轻就熟了。告诉你，一定要记牢动词的现在分词，过去式，过去分词，如果在这些小地方丢分，那才讨厌呢。比如：<span word="catch">catch</span> 的过去式和过去分词(<span word="caught">caught</span>，<span word="caught">caught</span>) 你可能就不知道吧 痛下决心，好好记一记吧。下面呢，我们就各个击破。先讲系动词。</p><p> 系动词：大概是最简单的动词了。你只需注意的是系动词除了<span word="be">be</span>的形式之外，还有<span word="become">become</span>，<span word="get">get</span>，<span word="grow">grow</span>，<span word="turn">turn</span>，<span word="sound">sound</span>，<span word="look">look</span>，<span word="smell">smell</span>，<span word="taste">taste</span>等，它们不能单独作谓语,必须和作表语的词语(如形容词, 名词等) 连用, 所以用的时候，可要小心为是呀！如：<span word="It">It</span> <span word="smells">smells</span> <span word="delicious">delicious</span>.(它闻起来味道很美)。<span word="delicious">delicious</span> 是形容词，不是副词。</p><p> 情态动词：首先要记住情态动词后必跟动词原形。<span word="must">must</span>和<span word="need">need</span>几乎是每年的必考题，这里我们重点讲一下。</p><p> <span word="must">must</span>的意思是应当，必须，侧重于说话者的主观看法，没有时态变化，其否定式是<span word="mustnt">mustnt</span>，在<span word="Must">Must</span> <span word="I">I</span>(<span word="we">we</span>) ....的疑问句中，须注意的是其否定回答常用<span word="neednt">neednt</span>。如：<span word="Must">Must</span> <span word="I">I</span> <span word="go">go</span> (我一定要走吗 ) <span word="No">No</span>,<span word="you">you</span> <span word="neednt">neednt</span>.(不，不必。)</p><p> <span word="need">need</span>意为需要。既可作实义动词，又可作情态动词，因此在用法上需要注意。作实义动词时，<span word="need">need</span>后跟名词，动名词，或不定式。如：<span word="I">I</span> <span word="need">need</span> <span word="to">to</span> <span word="go">go</span>. (我得走了。) 作情态动词时，后跟动词原形。如：<span word="You">You</span> <span word="neednt">neednt</span> <span word="come">come</span> <span word="tomorrow">tomorrow</span> <span word="if">if</span> <span word="you">you</span> <span word="are">are</span> <span word="busy">busy</span>. (如果你忙，明天就不必来了。)</p>
