一般现在时及三单2.doc

一般现在时态一、一般现在时的用法: 1、表示经常或者反复发生的动作. 如: 我每天吃午饭. I have lunch every day. 2、还表示现在存在的一种状态. 如：我姐姐是一位老师．My sister is a teacher. 3、客观真理，客观存在，科学事实例如：The earth moves around the sun. 地球绕着太阳转二、一般现在时态经常与often（经常）sometimes（有时）always（总是）usually（通常）等频率词连用，也经常与every day（每天）, every week（每周）, every month（每月）, every term（每学期）, every year（每年）, once a week （一周一次），twice a year（一年两次）等表示时间的词连用三、第三人称单数问题　　一般现在时中，当主语是第三人称单数时，即常在动词原形后加-s或-es第三人称单数变化，现归纳总结如下：1.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2.单个人名、地名或称呼作主语；用第三人称单数如：①Han Mei looks like her mother.韩梅看起来像她的母亲 ②Beijing is in China.北京在中国③Uncle Wang often makes cakes.王叔叔经常做蛋糕 3.单数可数名词或"this / that / the/ a +单数可数名词"作主语时，是第三人称单数如： ①The cat is Lucy's.这只猫是露茜的②This book is yours.这本书是你的③That car is red. 4.不定代词someone, somebody, nobody, everything, something等及指示代词this, that作主语时，第三人称单数　①Everyone is here.大家到齐了。

②There is something wrong with the watch.这块手表有毛病③This is a pen. 这是一支钢笔 ④That is an eraser.那是一块橡皮擦5.不可数名词作主语时为第三人称单数如： ①The milk is in the glass. ②The bread is very small.6.当数字或字母作主语时，看作第三人称单数如： ①"6" is a lucky number."6" ②"I" is a letter. 四、一般现在时分类：１．一般现在时态分为be 动词的一般现在时 1） be动词包括am，is，are. 中文为"是"， 这三个词的用法要随着主语的变化而变化 "am" 用于第一人称单数（I）; "is" 用于第三人称单数（he，she，it）; "are "用于第一人称复数（we），第二人称单数和复数(you), 第三人称复数（they） 可以记住以下顺口溜： am管 "我"， is管"，她，它，他"， are管"大家" 一般疑问句和否定句：把be 动词"am，is，are" 放在句首,回答时也要使用be动词；变为否定句时,把表示否定的not 放在 "am is are" 的后面。

注意：如果are not, is not放在句尾时，不能使用简写，必须写出整个单词Am I a teacher? Yes, I am. (No, I am not.) Are you his friend? Yes, you are. (No, you are not.)Is she a nurse? Yes, she is. (No, she is not.) 否定句为：I am not a teacher. You are not his friend. She is not a nurse.2）实义动词的一般现在时如果句子的动词不是be 动词 "am is are" 而是其他实义动词, 疑问句和否定句要借助于助动词"do"或者 "does"， 也就是说be 动词和实义动词原形不能同时使用 这里的 "do"，"does" 本身没有什么意义，只是帮助构成疑问句和否定句. 一般疑问句读时必须用降调."do"和 "does"的使用要随着人称的变化而变化 请看下面两组句子，注意区分他们的共同点和不同点I go to school every day. --I don't go to school every day.He goes to school every day. --He doesn't go to school every day.Do you go to school every day? --Does he go to school every day?Yes, I do. (No, I don't) --Yes, he does. (No, he doesn't)当主语是第三人称单数时， 肯定句为：主语+动词的s形式+宾语  否定句为：主语+助动词doesn't+动词原形+宾语 疑问句为：Does+主语+动词原形+宾语 肯定回答和否定回答也要使用助动词does.注：1）第三人称单数用了 does 后面就不用动词的s形式了,而用动词原形. 2）变为疑问句,要在句首加"do" ; 变为否定句, 要在动词前面加"do not", 可以简写为 "don't". 一、 写出第三人称单数：wash match guess study finish go snow carry have do get teach talk hope stop play say buy cut fly study like make take become come drive Leave ride give swim stop sit 二、 用所给动词的适当形式填空： 1.What time__ his father__(do) the work? 2.He ___(get) up at five o’clock. 3.__ you __(brush) your teeth every morning.4.What ___ ( do ) he usually ___( do ) after school? 5.Tom __ ( study ) English, Chinese, Maths, Science and Art at school. 6.
