一般现在时三单作文
一般现在时三单作文作为一个英语学习者，一般现在时中的三单形式可真是让我又爱又恨。
就说我那可爱的小表弟吧，他上小学三年级，正是开始接触英语的时候。
有一次我去他家，正赶上他写英语作业，那抓耳挠腮的样子，真是让人忍俊不禁。
“姐，这个三单到底是啥呀？怎么这么难！”小表弟皱着眉头，手里的铅笔都快被他咬秃了。
我笑着坐到他旁边，说：“别着急，姐给你讲讲。
”他那充满期待的小眼神立马看向了我。
“你看啊，比如说‘He likes apples.’这里的‘likes’就是三单形式。
当主语是第三人称单数，像‘he’‘she’‘it’或者是单个的人名，比如‘Tom’‘Lucy’，这时候后面的动词就要用三单形式。
”我尽量用简单的话给他解释。
小表弟似懂非懂地点点头，然后指着书上的一道题说：“那这个‘My mother ____ (cook) dinner every day.’这里该填啥？”我耐心地引导他：“你想啊，‘my mother’是第三人称单数，‘cook’这个动词就得用三单形式，所以要填‘cooks’。
”小表弟恍然大悟，“哦，原来是这样啊！”可没一会儿，又碰到难题了。
“那‘The dog ____ (run) very fast.’这个呢？”“还是三单形式哦，填‘runs’。
”我回答道。
小表弟一边写一边嘟囔：“这三单也太麻烦了，每个动词都要变。
”我拍了拍他的肩膀说：“虽然麻烦，但是掌握了规律就不难啦。
你多做几道题练习练习。
”接下来的时间，小表弟就在那埋头苦写，我在旁边时不时地给他指导一下。
“哎呀，错啦错啦，这个应该是‘She studies hard.’不是‘study’。
”“还有这个，‘The cat plays with the ball.’要用‘plays’。
”小表弟被我说得有点不耐烦了，“姐，你能不能别老打断我，让我自己想想。
”我赶紧闭嘴，看着他认真思考的样子，心里还挺欣慰。
过了好一会儿，小表弟终于做完了作业，长长地舒了一口气，“终于做完了，这三单可把我累坏了。

"I" is a letter. "I"是个字母。
四、动词三单变化规则1、一般情况下加S ：ask---asks learn----learns work---works get---gets like—likesplay—plays stay---stays2、以“s, x, ch, sh,o”结尾的，在词尾加“es”：teach－teaches wash----washes go－goes do－does3、以辅音字母加“y”结尾的，先将“y”变为“i”，然后在加“es”：study－studies fly－flies cry---cries try---tries carry－carries worry －worries4、以元音字母加Y的，直接加S，（此种情况可直接归入第1类）如say—says5、记住3个特殊的：Be动词（is are）的三单－ishave的三单－hasDo的三单—does五、句型转换一、陈述句变一般疑问句、否定句1、Be型、情态动词型否定句：直接在be动词或情态动词后面加not.疑问句：则把be动词或情态动词(can,could等等)提到主语的前面例：①陈述句：She is a student.疑问句→Is she a student?否定句→She is not a student.②陈述句：I can swim.疑问句→Can you swim? yes,I can. No,I can’t.否定句→I can not swim.2、Do型否定句：主语+ don’t/ doesn’t + 谓语动词原形疑问句：Do / Does + 主语+ 动词原形例：①陈述句：We get up at 7:00 every morning.否定句→We don’t get up at 7:00 every morning.疑问句→Do you get up at 7:00 every morning?②陈述句：She has a little brother.否定句→She doesn’t have a little brother.疑问句→Does she have a little brother?3、注意“变变变变”（1）I、we—>you、you（2）句号变问号；（3）Does（三单）、Did（过去式）来帮忙，动词变V原；（4）some->any something->anything somebody-> anybody already->yet too->eitherboth->neither all->noneeg:Are you from Japan﹖Yes, I am．/ No, I'm not．Is her sister doing her homework now﹖Yes, she is．/ No, she isn't．Does he work in a bank﹖Yes, he does．/ No, he doesn't．Do you live near your school﹖Yes, I do．/ No, I don't．Can you speak French﹖Yes, I can．/ No, I can't．May I go home now﹖Yes, you may．/ No, you mustn't．二、陈述句变特殊疑问句（不能用yes/no回答的疑问句）1、常见的疑问词when：问时间(回答用At/ On...等)where：哪里（状语）who ：谁( 回答用He is...She is... They are...等）whom：谁（宾格）whose：谁的(回答用It is.. These/Those are等)what ：什么How：怎么样(对近况提问，回答用形容词，问程度）which：哪一个，哪个why：为什么(回答用Because，问原因)记法：特殊疑问词的开头一般是wh或h；注意：特殊疑问句一般读降调(↓)常见的疑问短语what time：问时间点what color：什么颜色（表语）what weather：什么天气what subject：什么学科what job：什么职业what nationality：对国籍提问what kind：哪一种类型-How fast：多快（速度）How many：多少数量（可数）How much：多少钱价格（不可数）How long：多长(可用于时间，问做多长时间）How often：多少次（问频率）（频率副词）How far：多远路程How soon：多久How old：多少岁2、特殊疑问句有两种语序：(1)如疑问词作主语或主语的定语，即对主语或主语的定语提问，其语序是陈述句的语序：Who is singing in the room﹖whose bike is broken﹖(2)如疑问词作其他成分，即对其他成分提问，其语序是：特殊疑问词+一般疑问句【即：特殊疑问词+be/助动词/情态动词+主语+谓语】What does she like?What class are you in﹖Where are you from﹖What time does he get up every morning﹖How do you know﹖(3)就划线部分提问解题方法：一换二变三提前一换：找出正确的疑问词或词组替换划线部分什么东西->what, 地点->where 时间->when, 怎么样->how多少->how many(可数) how much(不可数)动作划线->看形式，然后选择助动词，做的事情用what Eg: They read English books in the afternoon.
