名词的复数形式与动词第三人称单数形式的区别这段时间，在讲解第三人称单数形式时，我常常跟学生提到，这段时间，在讲解第三人称单数形式时，我常常跟学生提到，第三人称单数形式的变化规律一般跟复数一般变化规律相似，基本情况下加-s.但是一次课堂上我问到，动词以- ch结尾时，它的第三人称单数是什么，不少同学回答是加-es我又让他们举个例子，有学生给我举了：peaches，我突然间觉得，教学中有失误，学生将名词的复数形式和动词的第三人称单数形式混淆了。
既然提到，就有必要跟学生讲清楚，帮助他们做一个比较。
首先，我帮助他们理解了两种不同的词性。
为什么叫复数？显然是不只一个。
什么东西可以一个一个地数呢？物品类。
物品通常指名词，所以，我告诉学生：复数是属于名词的。
而动词第三人称单数形式，顾名思义是属于动词的。
什么是动词，就是有动态的意思的，包括外在变化和心里变化的。
明白了他们各自的所属性，再对这两种变化规律作一个比较。
名词复数形式和动词第三人称单数形式性质上截然不同，但它们在构成方式上有异也有同。
试比较如下：一、构成方式的相同点1.两者一般在词尾加-s 清辅音后读作，浊辅音和元音后读作[z]。
如：名词复数：bed(beds), tree(trees),动词第三称单数：help(helps), play(plays)2.两者以s ,x ,ch ,sh 结尾的词，在词尾加-es,原词尾已有e，一般只加-s 都读作[iz] [iz]。
如：名词复数：box(boxes), orange(oranges)动词第三人称单数：wash(washes), close(closes)3.以辅音字母加-y 结尾的词，先变y 为i，再加-es，读作[iz]。
如：名词复数：factory(factories), baby(babies)动词第三人称单数：fly(flies), study(studies)二、构成方式的不同点1.名词方面（1）有些名词的单、复数形式相同。
如：sheep(sheep), Chinese(Chinese)（2）有些名词的复数形式是特殊的，不规则的。
如：man(men),child(children)（3）以o 结尾的名词，有的加s，也有的加es。
如：radio(radios), photo(photos),tomato(tomatoes)（4）以fe 结尾的先变f(e)为v，再加es。
如：knife(knives),leaf(leaves)2.第三人称单数形式方面（1）以o 结尾的动词加es。
如：go(goes), do(does)（2）不规则的。
如：be-is，have(has)【※内容链接】哪些主语是第三人称单数？1．人称代词he，she, it.He likes watching TV.2．单个人名、地名作主语，比如Ken,ShenzhenKen runs fast.
