第三人称单数用法讲解及练习题第一节：第三人称单数用法的基本规则在英语语法中，第三人称单数形式的动词使用规则与其他人称形式有所不同。

下面是关于第三人称单数用法的基本规则：1. 动词在第三人称单数形式中的变化：- 一般现在时：动词原形+“s”或“es”，如“he walks”，“she dances”。

- 可数名词的所有格：名词+ “’s”，如“John’s car”。

- 前置冠词“a”在变为“an”时需要考虑后续单词的发音，如“an apple”，“an hour”。

2. 一些特殊情况和例外：- 以“o”结尾的动词通常加上“es”，如“he goes”，“she does”。

- 以“s, ss, sh, ch, x”结尾的动词加上“es”，如“he passes”，“she washes”。

- 以辅音字母+y结尾的动词，将“y”变为“ies”，如“he cries”，“she tries”。

- 以“f”或“fe”结尾的名词或形容词，将“f”或“fe”变为“ves”，如“wives”，“lives”。

动词第三人称单数词尾变化及读音动词第三人称单数词尾变化有三种形式。

(1)一般动词在词尾加 -s，-s 在清辅音后读／ s／，在浊辅音或元音后读／ z／ds 读／ dz／， ts 读／ ts／。

如：help→helps／helps／， know→knows／n uz／， get→gets／gets／，read→reads／ri dz／(2)以字母 s，x，ch，sh 或有些以 o 结尾的动词加 -es，-es 读／ iz／。

如：①stop－stops [s] ; make－makes [s]2、以辅音字母加“y”结尾的，要先将“y”变为“i”，然后在加“es”读[iz] 如：fly－flies [z]；carry－carries [z]3、以“s, x, ch, sh”结尾的，在词尾加“es”，发音为[iz] 如：teach－teaches [iz]; watch－watches [iz]4、以“o”结尾的动词，加“es”，读[z] 如：go－goes [z]二.动词变现在分词的变化规则:1. 直接在动词原形后面加-ing。

例如：food, meat, bread, tea, water, milk, ink, orange, drink, rice, 等。

(2).可数名词的单数前什么时候用a，什么时候用an? 答：以元音音标开头的用an,以辅音音标开头的用a。

注意：我们看的是音标，而不是元音字母。

1>选择a或an或者不填(用/来表示)pen bag apple big apple banana orange oranges orange pen hour 小时house [haus]房子umbrella 雨伞university大学2>用a/an填空：①Is it Chinese book or English book? ②This is ring, and it is orange ring.③Mary is English teacher.

动词第三人称单数形式构成规则及练习题动词第三人称单数形式构成规则动词原形变第三人称单数旳规则与发音规律同名词单数变复数大体相似，请认真观测。

1、大多数动词在词尾加“S”在清辅音后发音为[s]，在浊辅音及元音后发音为 [z]。

如：①make－makes [s]② play－plays [z]2、以辅音字母加“y”结尾旳，要先将“y”变为“i”，然后在加“es”读[iz] 如：fly－flies [z]； carry－carries [z]3、以“s, x, ch, sh”结尾旳，在词尾加“es”，发音为[iz] 如：teach－teaches [iz]; watch－watches [iz]4、以“o”结尾旳动词，加“es”，读[z] 如：go－goes [z] do－does [z下面几种动词变为单数时，原词旳元音部分旳发音发生了较大旳变化，请注意记忆。

如：1、do [du:]－does [dz]2、say [sei]－says [sez]一起读做[iz]。

如： close－closes [iz] be动词涉及：am， is， are。

第三人称单数用 is；复数用are，除上述规律外，还应注意下面三点：1. 动词 have ，遇到主语是第三人称单数时，要用 has；动词be 旳第三人称单数形式是is。

2. 具有动词第三人称单数形式旳句子变否认句时，要用doesn't + 动词原形，如：He goes to school at six in the morning. (变否认句)→ He doesn't go to school at six in the morning.3. 对具有动词第三人称单数形式旳句子提问时，要用助动词does，如：She goes home at five every day. (对划线部分提问)→ When / What time does she go home every day?一般目前时中旳第三人称单数形式在一般目前时中，当主语是第三人称单数时，谓语动词要用第三人称单数形式，即常在动词原形后加-s或-es。

第三人称单数用法讲解及练习题嘿，伙计们！今天我们来聊聊一个非常有趣的话题——第三人称单数用法。

你们知道吗，这个小小的动词变形可是英语学习中的一大难题。

别担心，我会让你们轻松掌握这个技能的！现在就让我们开始吧！我们来看看第三人称单数是什么。

简单来说，就是当主语是单数时，动词要加上“-s”或“-es”。

比如，我们说“I eat an apple”，但是如果说“he eats an apple”，那么动词就要变成“eats”。

明白了吗？接下来，我们来谈谈第三人称单数的用法。

其实，第三人称单数的用法有很多种，但是最重要的是要学会在不同的情境下使用正确的形式。

下面，我就给大家举几个例子：1. 当主语是第三人称单数时，我们在谓语动词后面加“-s”或“-es”。

比如，“He watches TV every night”。

这里的主语是“he”，所以谓语动词要变成“watches”。

2. 当主语是第一人称复数时，我们在谓语动词后面加“-s”。

比如，“We are students”。

这里的主语是“we”，所以谓语动词要变成“are”。

3. 当主语是第二人称单数时，我们在谓语动词后面加“-s”。

比如，“You are my friend”。

这里的主语是“you”，所以谓语动词要变成“are”。

4. 当主语是第一、二、三人称复数时，我们在谓语动词后面加“-s”或“-es”。

比如，“They play basketball together”。

这里的主语是“they”，所以谓语动词要变成“play”。

好了，现在你们应该对第三人称单数有了一定的了解了吧？接下来，我们来练一练。

我会给你一个句子，然后请你把主语和谓语动词改成第三人称单数的形式。

试试看吧！1. My sister is a doctor.(我的姐姐是一名医生。

)→ My sister is a doctor.(我的姐姐是一名医生。

)2. We are students.(我们是学生。

动词第三人称单数词尾变化及读音动词第三人称单数词尾变化有三种形式。

(1)一般动词在词尾加-s，-s在清辅音后读／s／，在浊辅音或元音后读／z／ds读／dz／，ts读／ts／。

如：help→helps／helps／，know→knows／n?uz／，get→gets／gets ／，read→reads／ri?dz／(2)以字母s，x，ch，sh或有些以o结尾的动词加-es，-es读／iz ／。

如：guess→guesses／'??siz／，fix→fixes／'fiksiz／，teach→teaches／'ti?t?iz／，wash→washes／'w??iz／注意：go→goes／??uz／，do→does／d?z／(3)以辅音字母+y结尾的动词，先变y为i，再加-es，-ies读／iz ／。

如：carry→carries／'k?riz／，fly→flies／flaiz／注：在play→plays／pleiz／，say→says／sez／中，字母y前为元音字母，第三人称单数形式直接在动词后面加-s。

(4)特殊词例外。

如：be→is，have→has以不发音字母“e”结尾的开音节词，如果尾音是[s]，[z]时，加“s”后字母“e”发音，与所加“s”，一起读做[iz]。

如：close－closes [iz]一般现在时练习（一）一、用词的适当形式填空time_________ his father_________(do) the work?_________(get) up at five o’clock.you _________(brush) your teeth every morning？________ ( do ) he usually ________( do ) after school?________ ( study ) English, Chinese, Maths, Science and Art at school.6.

动词第三人称单数形式构成规则及练习题动词第三人称单数形式构成规则动词原形变第三人称单数的规则与发音规律同名词单数变复数大致相同，请认真观察。

1、大多数动词在词尾加“S”在清辅音后发音为[s]，在浊辅音及元音后发音为 [z]。

如：①make－makes [s]② play－plays [z]2、以辅音字母加“y”结尾的，要先将“y”变为“i”，然后在加“es”读[iz] 如：fly－flies [z]； carry－carries [z]3、以“s, x, ch, sh”结尾的，在词尾加“es”，发音为[iz] 如：teach－teaches [iz]; watch－watches [iz]4、以“o”结尾的动词，加“es”，读[z] 如：go－goes [z] do－does [z下面几个动词变为单数时，原词的元音部分的发音发生了较大的变化，请注意记忆。

如：1、do [du:]－does [dz]2、say [sei]－says [sez]一起读做[iz]。

如： close－closes [iz] be动词包括：am， is， are。

第三人称单数用 is；复数用are，除上述规律外，还应注意下面三点：1. 动词 have ，遇到主语是第三人称单数时，要用 has；动词be 的第三人称单数形式是is。

2. 含有动词第三人称单数形式的句子变否定句时，要用doesn't + 动词原形，如：He goes to school at six in the morning. (变否定句)→ He doesn't go to school at six in the morning.3. 对含有动词第三人称单数形式的句子提问时，要用助动词does，如：She goes home at five every day. (对划线部分提问)→ When / What time does she go home every day一般现在时中的第三人称单数形式在一般现在时中，当主语是第三人称单数时，谓语动词要用第三人称单数形式，即常在动词原形后加-s或-es。
