Grammar Do verbs
Unit 2
We are family.
动词的分类一共分为四大类：
①系动词；②实义动词；
③情态动词；④助动词。
系动词：
无动词意义，连接主语和表语。(eg. be存在系动词 (am /is/ are )/ 感官系动词：look 看起来 sound 听起来 taste 尝起来 )
实义动词：
有实际意思的动词。可以完整的作谓语。(eg. like eat drink think know)
情态动词：
表示情绪和态度的，可以理解成帮助增加感彩的词类。(must may can should could等 )
助动词：
帮助实义动词构成疑问、否定等情况的词类。本身没实际意义(do does )
句子结构：主语+系动词+表语
句子结构：主语+谓语+其他
谓语：句子里面的谓语是在主语的后面，准确来说，谓语是动词。
实义动词
I have a big room.
we play tennis together.
You like blue too.
They need to keep their room tidy
My parents like playing ping-pong.
主语：第一人称单数
主语：第一人称复数
主语：第二人称
主语：第三人称复数
主语：相当于第三人称复数 they
总结： 当主语是第一人称单或复数，第二人称单或复数，第三人称复数，谓语动词用原形
主谓一致
Xiao Wanzi swims every Sunday.
Her sister reads a lot.
Her dad plays baseball with his friends.
Her mum likes gardening.
Her grandpa loves playing chess.
主语：第三人称单数she
主语：第三人称单数 she
主语：第三人称单数he
主语：第三人称单数she
主语：第三人称单数he
总结： 当主语是第三人称单数，谓语动词要加“s”
在动词后加“s”的规则

know---knows
help---helps
2.以“s, x, sh, ch, o”结尾的动词加“es”

3. 以“辅音字母+y”结尾的动词，变y为i加“es”。

4. 不规则变化：have---has
规则 示例
一般情况下在词尾加-s put-puts
以s、x、sh、ch,o 等结尾的词，在词尾加-es wash-washes
以“辅音字母+y”结尾的词，变y为i再加-es study-studies

Grammar Focus
谓语动词的三单形式
一般情况下，直接在动词后+s，如：
like → spend → use →
若动词本身以s,x,sh,ch,o结尾，则在动词后+es，如：
watch → fix → finish →
若动词本身以辅音字母+y结尾，则改y为i加es，如：
study → satisfy → purify →
likes
spends
uses
watches
fixes
finishes
studies
satisfies
purifies
你能写出play的三单形式吗？
plays，元音字母加y结尾的单词直接加s
注意：
英语中也有一部分单词是特殊情况，需要我们牢记在心里，如：be → is/am/are
have → has
do → does
go → goes
1. I like playing tennis. (he)
2. They play the erhu well. (she)
3. Tom and Marry often play with Helen. (Tom)
