语法讲解：可数名词与不可数名词的区别
<p> 可数名词有单数、复数之分。可数名词的单数形式通常为名词本身，一般要在其前加冠词或其他限定词。不可数名词指不能计数的名词，包括物质名词和抽象名词。</p><p> 一、可数名词前可用具体的数词来表示具体的数量。如：<span word="two">two</span> <span word="apples">apples</span>, <span word="four">four</span> <span word="books">books</span>等。不可数名词前通常用单位词 <span word="of">of</span>来表示数量。如： <span word="a">a</span> <span word="piece">piece</span> <span word="of">of</span> <span word="paper">paper</span>, <span word="three">three</span> <span word="pieces">pieces</span> <span word="of">of</span> <span word="paper">paper</span>等。</p><p> 二、可数名词是可以用来计数的名词。可数名词有单数和复数形式。如：<span word="desk">desk</span>-<span word="desks">desks</span>, <span word="apple">apple</span>-<span word="apples">apples</span>等。不可数名词是不可以直接用来计数的名词。不可数名词没有复数形式，只有单数形式。如：<span word="some">some</span> <span word="bread">bread</span>， <span word="a">a</span> <span word="little">little</span> <span word="milk">milk</span>等。</p><p> 三、单数可数名词表示泛指时，前面要用不定冠词<span word="a">a</span>(<span word="an">an</span>)，表示特指时，前面要用定冠词<span word="the">the</span>;而不可数名词前不能用<span word="a">a</span>(<span word="an">an</span>)修饰，表示特指时，前面一定要用定冠词<span word="the">the</span>。如：<span word="He">He</span> <span word="is">is</span> <span word="a">a</span> <span word="factory">factory</span> <span word="worker">worker</span>.他是一名工人.<span word="No">No</span> <span word="one">one</span> <span word="can">can</span> <span word="see">see</span> <span word="air">air</span>. 没有人能看见空气。</p><p> 四、可数名词和不可数名词前都可以用<span word="some">some</span>, <span word="any">any</span>, <span word="a">a</span> <span word="lot">lot</span> <span word="of">of</span>, <span word="lots">lots</span> <span word="of">of</span> 等来修饰，表示一些，许多。如：</p><p> <span word="There">There</span> <span word="are">are</span> <span word="some">some</span> <span word="oranges">oranges</span> <span word="on">on</span> <span word="the">the</span> <span word="desk">desk</span>. 桌子上有一些桔子。</p><p> <span word="There">There</span> <span word="is">is</span> <span word="a">a</span> <span word="lot">lot</span> <span word="of">of</span> <span word="water">water</span> <span word="in">in</span> <span word="the">the</span> <span word="bottle">bottle</span>. 瓶里有许多水。</p><p> 五、对可数名词前的修饰语提问用<span word="how">how</span> <span word="many">many</span>; 对不可数名词前的修饰语提问用<span word="how">how</span> <span word="much">much</span>。 如：</p>
