2017同步攻关高考英语一轮复习学案：语法部分 第1讲 冠词
<p> 第1讲 冠词</p><p> 冠词是用在名词前面，说明名词所表示的人或事物的词。冠词是虚词，本身不能单独使用，也没有词义，它用在名词的前面，帮助指明名词的含义。英语中的冠词有三种，一种是定冠词(<span word="the">the</span> <span word="Definite">Definite</span> <span word="Article">Article</span>)，另一种是不定冠词(<span word="the">the</span> <span word="Indefinite">Indefinite</span> <span word="Article">Article</span>)，还有一种是零冠词(<span word="Zero">Zero</span> <span word="Article">Article</span>)。不定冠词<span word="a">a</span> (<span word="an">an</span>)与数词<span word="one">one</span> 同源，是“一个”的意思。<span word="a">a</span>用于辅音音素前，一般读作[]，而<span word="an">an</span>则用于元音音素前，一般读做[<span word="en">en</span>]。</p><p> 一、不定冠词的用法</p><p> 【完成例句】</p><p> (1)门口有个警察。</p><p> <span word="There">There</span> <span word="is">is</span> <span word="a">a</span> <span word="policeman">policeman</span> <span word="at">at</span> <span word="the">the</span> <span word="door">door</span>.</p><p> 【结论1】不定冠词用在单数可数名词前表示“某一个”。</p><p> 【翻译句子】</p><p> (2) <span word="A">A</span> <span word="car">car</span> <span word="must">must</span> <span word="be">be</span> <span word="insured">insured</span>.</p><p> 汽车一定要上保险。</p><p> (3) <span word="A">A</span> <span word="soldier">soldier</span> <span word="must">must</span> <span word="obey">obey</span> <span word="orders">orders</span>.</p><p> 军人必须服从命令。</p><p> 【结论2】 不定冠词用在单数可数名词之前，表示“某一类”，强调“任何一个，每个”。</p><p> 【完成例句】</p><p> (4)房间里有个箱子。这个箱子很重。</p><p> <span word="There">There</span> <span word="is">is</span> <span word="a">a</span> <span word="box">box</span> <span word="in">in</span> <span word="the">the</span> <span word="room">room</span>. <span word="The">The</span> <span word="box">box</span> <span word="is">is</span> <span word="heavy">heavy</span>.</p><p> 【结论3】不定冠词用于头一次出现的单数名词之前。</p><p> 【完成例句】</p>
