The man who has never been to the Great Wall is not a real man. Tomorrow is Tuesday.三单变化：1.多数在动词后s play plays like likes（1）直接在动词词尾加-s.ask-asks work-works get-gets stay-stays（2）以字母s, x, ch, sh或o结尾的动词，在词尾直接加-es.watch-watches wish-wishes fix-fixes do-doesgo-goes pass-passes wash washes（3）以“辅音字母加 - y”结尾的动词，要先变y为i再加-es.try-tries study-studies cry-cries fly-flies cry cries2.不规则变化：be- is are have-has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。但有些同学们对于哪些主语是第三人称单数还不十分清楚，现归纳总结如下： 一、人称代词he, she, it是第三人称单数。如： He likes watching TV. 他喜欢看电视。 She has lunch at twelve. 她十二点吃午餐。 It looks like a cat. 它看起来像只猫。 二、单个人名、地名或称呼作主语；是第三人称单数。如： Han Mei looks like her mother. 韩梅看起来像她的母亲。 Beijing is in China. 北京在中国。 Uncle Wang often makes cakes. 王叔叔经常做蛋糕。 三、单数可数名词或this / that / the+单数可数名词作主语时，是第三人称单数。如： A horse is a useful animal. 马是有用的动物。 This book is yours. 这本书是你的。 That car is red. 那辆小汽车是红色的。 The cat is Lucys. 这只猫是露茜的。 四、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。如： Everyone is here. 大家到齐了。 There is something wrong with the watch. 这块手表有毛病。 This is a pen. 这是一支钢笔。 That is an eraser. 那是一块橡皮擦。 五、不可数名词作主语时为第三人称单数。如： The milk is in the glass. 牛奶在玻璃杯里。 The bread is very small. 那面包很小。 六、当数字或字母作主语时，看作第三人称单数。如： 6 is a lucky number. 6是个吉利数字。 I is a letter. I是个字母。 Hello, boys and girls.我是一般现在时，你们想知道我的故事吗？Let me tell you!首先，介绍我的本领。我的本领有三样：1.表示事物或人物的特征、状态。如：The sky is blue.天空是蓝色的。2.表示经常性或习惯性的动作。如：I get up at six every day.我每天六点起床。3.表示客观现实。如： The earth goes around the sun.地球绕着太阳转。第二，请看我的面目-构成：1. be动词：主语+be(am,is,are)+其它。如：I am a boy.我是一个男孩。2.行为动词：主语+行为动词(+其它)。如：We study English.我们学习英语。当主语为第三人称单数(he, she,it)时，要在动词后加-s或-es。如：Mary likes Chinese.玛丽喜欢汉语。第三，我的变化-否定句、一般疑问句、特殊疑问句：1. be动词的变化。否定句：主语+ be + not +其它。如：He is not a worker.他不是工人。 一般疑问句：Be +主语+其它。 如：-Are you a student? -Yes. I am. / No, Im not.特殊疑问句：疑问词+一般疑问句。如：Where is my bike?2.行为动词的变化。 否定句：主语+ dont( doesnt ) +动词原形(+其它)。如： I dont like bread. 当主语为第三人称单数时，要用doesnt构成否定句。如： He doesnt often play. 一般疑问句：Do( Does ) +主语+动词原形+其它。如： - Do you often play football? - Yes, I do. / No, I dont. 当主语为第三人称单数时，要用does构成一般疑问句。如： - Does she go to work by bike? - Yes, she does. / No, she doesnt.下次见到我时，千万不要忘记我是一般现在时啊！See you next time!一般现在时（1）一、be动词与行为动词同时出现在句子中例：We are plant (plant) the trees in spring.答案：plant解析：学生往往会用汉语的思维方式去翻译，就成了“我们是在春天植树”。这是学习英语最忌讳的，要看语法是不是正确，在英语中，be是表状态，do是表动作，两种动词不能同时出现在句子中，可记住如下口诀：“英汉语言有差异，be 、do不能放一起，仔细琢磨细分析，语法千万要牢记。”二、单三人称形式易出错例：1 He plaies (play) football very well.2 Danny gos (go) to school at 7:10.答案：1 plays 2 goes解析：1以辅音字母加y结尾的动词变单三人称形式才能把y换成i再加es；2与名词变复数不同，变单三人称形式以o结尾的词要加es.三、在句式变换时易出错例：1 Does Jenny has (has) a good friend?2 Brian doesnt lives (not live) in China.答案：1 Does have 2 doesnt live解析：单三人称做主语的一般现在时做句式变化时，可记住如下口诀：“见助动，用原形”。此口诀也可推广用于一般过去时态中。e.g. He didnt go home yesterday.四、对do的理解易出错例：We dont (not do) our homework in the afternoon.答案：dont do解析：do是一个比较难理解的词，它有三个含义: a)是所有行为动词的总称；b)是助动词，无实义；c)是一个具体的行为动词“做，干”。此句中给出的do指“做，干”，not指把此句变为否定句，故须在do前加助动词dont。五、对主语的数判断有误例： Li Ming with me are (be) in Beijing.答案: is解析:表面一看是“我和李明两个人在北京”，但with在此做伴随状语，不能做主语，故用is.另外，宾语从句中，从句部分若是表示客观真理，不管主句是何时态，从句都要用一般现在时；在时间和条件状语从句中，主句表将来，从句要用一般现在时。一、写出下列动词的第三人称单数形式。(讨论第三人称单数形式的变化规则)Model: clean cleans1) watch _ 2) have _ 3) cook_ 4) go _ 5) fly _ 6) make _ 二用动词的正确形式填空。1.We often_(play) in the playgound.2.He _(get) up at six oclock.3._you _(brush) your teeth every morning.4.What_(do) he usually_(do) after school?5.Danny_(study)English,Chinese,Maths, Science and Art an school.6.Mike sometimes _(go) to the park with his sister.7.At eight at night, she _(watch) TV with his parents.8._ Mike_(read) English every day?9.Tom (swim) in the river now.10.Its eight oclock now.
