一般现在时中动词的第三人称单数变化规则
初中一般现在时及三单动词的变化规则
初中一般现在时及三单动词的变化规则
一般现在时的构成：
肯定句：主语+动词原形+其他成分
否定句：主语 + do/does not + 动词原形 + 其他成分
疑问句：(特殊疑问词) + do/does + 主语 + 动词原形 + 其他成分三单动词的变化规则：
一般现在时第三人称单数的动词变化规则是在动词原形末尾加上 -s 或 -es。
大多数动词直接在原形后加-s：
例如：play → plays
study → studies
以 -sh, -ch, -s, -x, -o结尾的动词，在原形后加 -es：
例如：watch → watches
teach → teaches
miss → misses
fix → fixes
do → does
其他一些特殊情况：
以辅音字母+y结尾的动词，将y变为i，再加-es：
例如：fly → flies
study → studies
以元音字母+y结尾的动词，直接加-s：
例如：play → plays
enjoy → enjoys
以-o结尾的动词，大多数加-es：
例如：do → does
go → goes
但也有例外，像是have、go这些常用的动词变化为has和goes。
需要注意的是，不可数名词和第三人称单数主语时，一般现在时动词不变化，依然使用动词原形：
例如：Water boils at 100 degrees Celsius.
She sings beautifully.。

第三人称单数变化规则
一般现在时动词三单变化规则
一般现在时动词三单变化规则一般现在时是英语语法中最基本的时态之一。
当我们谈论一种普遍的情况、习惯或者说一个真理时，我们都会用到这个时态。
在一般现在时中，动词的变化分为两种情况：一是非第三人称单数，二是第三人称单数。
一、非第三人称单数的动词变化规则：在非第三人称单数时，大多数动词的变化规则是在动词原形后面加上s或es，这取决于动词的结尾是什么。
如：I like to swim.（我喜欢游泳。
）She works hard.（她工作努力。
）They play tennis every weekend.（他们每周末打网球。
）但是，当动词的结尾是s, x, z, ch, sh等半元音或辅音加上o 时，要在动词原形后面加上es。
如：He goes to school every day.（他每天去学校。
）She fixes her bike herself.（她自己修自行车。
）The boss buzzes around the office.（老板在办公室里四处走动。
）二、第三人称单数的动词变化规则：在第三人称单数时，大多数动词的变化规则是在动词原形后面加上s或es，这取决于动词的结尾是什么。
如：He runs every morning.（他每天早上跑步。
）She reads a book before bed.（她睡前看一本书。
）The cat eats fish.（猫吃鱼。
）但是，当动词的结尾是s, x, z, ch, sh等半元音或辅音加上o 时，要在动词原形后面加上es。
另外，以辅音+y结尾的动词，要改为以i结尾，再加es。
如：He goes to school every day.（他每天去学校。
）She fixes her bike herself.（她自己修自行车。
）The boss buzzes around the office.（老板在办公室里四处走动。
）He studies hard every day.（他每天努力学习。
