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。
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, 其中可以简写为:is not---- isn't ;are not---- aren't;am not 没有简写形式。
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? ----------- D oes he go to school every day?Yes, I do. (No, I don't) -------------- Y es, 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".课堂练习一、把下列句子改成一般疑问句并做肯定、否定回答。
