专项二 动词第三人称变化规则
在一般现在时中，当句子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，现归纳总结如下。
1. 主语是第三人称单数情况：
(1)人称代词he、she、it是第三人称单数。
eg. ①He _______ cars.
他喜欢车。
②She _______ to school at seven.
她七点去上学。
③It _______ a good name.
它有个好名字。
(2)单个人名、亲朋好友等称呼作主是第三人称单数。
eg. ①Pat always _______ bread for breakfast．
Pat早饭经常吃面包。
②Miss Wang _______ the flowers once a day．
王老师给花一天浇水一次。
③Aunt Mary usually _______ cakes.
玛俪阿姨经常做蛋糕。
④My mother _______ the dishes everyday．
我妈妈每天都洗碗。
(3)单数可数名词或this/that/the+可数名词作主语时，是第三人称单数。
eg. ① A horse _______ a useful animal. 马是有用的动物。
② This book _______(belong) to you. 这本书属于你。
③ That car _______ red. 那辆小汽车是红色的。
④ The girl _______ a red umbrella. 这个女孩有一把红色的伞。
(4)不定代词 someone，somebody，nobody， everything，something等及指示代词this，that作主语时，是第三人称单数。
eg. ① Everyone _______ (be)here. 大家到齐了。
② There _______ something wrong with the watch. 这块手表有毛病。
③ This _______ a pen. 这是一支钢笔。
④ That _______ an eraser. 那是块橡皮擦。
(5)不可数名词作主语时为第三人称单数。
eg. ①The milk is in the glass. 牛奶在玻璃瓶里。
② The bread is very small. 那面包很小。
(6)当数字或字母作主语时为第三人称单数。
eg. ①“6” is a lucky number. 6是吉利数字。
②“I” is a letter I是个字母。
2. 第三人称单数形式的构成。
(1)一般直接在词尾加-s
eg. work - _______ live -_______ make -_______
(2)以s，x，ch，sh，o等结尾的单词加-es
eg. miss - _______ fix - _______ finish- _______
go - _______ do- _______ teach = _______
(3)特殊变形的有：have - has
问句中遇到第三人称单数时，要用助动词does，动词变为原形。
eg. ①What does she _______ for breakfast 她早饭吃什么？
②When does he _______ his teeth 他什么时候刷牙？
③How often does your sister _______ every week 你姐姐一周锻炼几次？
(4)关于do和does的使用方法
①第三人称单数用了does后面就不用动词的s/es形式了，而用动词原形。
②变为疑问句，要在句首加do/does；变为否定句，要在动词前面加do not/does not可以简写为 don’t/ doesn’t。
背： I do, you do, we do, they do, Jack and Tom do,
he does, she does, it does, lily does

三、肯定句改特殊疑回句的方法（句子划线部分提问）——四步法
1. 在一般疑问句的基础上，句首添加一个特殊疑可词即可，可根据划线部分确定是什么疑问词。
2. 接着找be动词或can，shall，will等放在疑可词后面，若没有则请助动词 do/does/did帮忙，写在疑问词后面， how many除外，必须先写物品，再写be动词等。
3. 划线部分内容去掉后，剩下的内容照抄（some改成any, my改成your）
4. 句点改成问号。
eg. He writes to his father every week.(划线部分提问)
