小学英语语法-一般现在时详细讲解一般现在时是英语语法中最基础也是最常用的时态之一。
它表示的是习惯性、经常性和普遍性的行为或状态。
在本文中,我将详细介绍一般现在时的形式、用法和注意事项。
一、一般现在时的形式一般现在时的肯定句的基本结构是:主语+谓语动词+其他。
谓语动词在第三人称单数形式时要加上-s或-es。
例如:- I eat breakfast every morning.(我每天早上吃早饭。
)- She goes to school by bus.(她坐公共汽车去学校。
)否定句的结构是:主语+do not/does not+动词原形+其他。
例如:- I do not like coffee.(我不喜欢咖啡。
)- He does not play football.(他不踢足球。
)疑问句的结构是:Do/Does+主语+动词原形+其他?例如:- Do you like ice cream?(你喜欢冰淇淋吗?)- Does she go to the park every weekend?(她每个周末去公园吗?)二、一般现在时的用法第1页/共4页1. 表示习惯或经常性的动作:- I write in my diary every night.(我每天晚上写日记。
)- They play basketball every Sunday.(他们每个星期天打篮球。
)2. 表示客观事实、自然规律或科学真理:- Water boils at 100 degrees Celsius.(水在100摄氏度时煮沸。
)- The sun rises in the east.(太阳从东方升起。
)3. 表示感觉、想法和喜好:- I love chocolate.(我喜欢巧克力。
)- He hates to wake up early.(他讨厌早起。
)4. 表示现时状态或现时临时的动作:- I am a student.(我是一个学生。
一:一般现在时:表示经常性的事情。
时间状语:often经常, usually通常, always总是,every 每个, sometimes有时,at…在几点钟只有第三人称单数用动词三单,其余动词均用原形三单变化:多数在动词后加s play—plays like—likes 以s,x,sh,ch,o结尾的动词加es go —goes wash--washes 以辅音字母加y结尾,把y改i再加es fly—flies二:基本结构:动词原形(如主语为第三人称单数,动词上要改为第三人称单数形式)三:否定形式:am/is/are+not;此时态的谓语动词若为行为动词,则在其前加don't,如主语为第三人称单数,则用doesn't,同时还原行为动词。
四:一般疑问句:把be动词放于句首;用助动词do提问,如主语为第三人称单数,则用does,同时,还原行为动词。
五:但是,动词to be 和to have 的一般现在时的形式特殊如下:一般动词的词形变化To be 的词形变化To have 的词形变化I know it I am a student I have a pen.You know it. You are a student You have a penHe (she) knows it. He (she) is a student. He (she)has a pen.We (you,they) know it. We (you,they) are students. We (you,they) have pens.3、动词A)第三人称单数当动词是第三人称单数时,动词应该像名词的单数变动词那样加s,如下:一)一般在词后加s。
如:comes, spells, waits, talks, sees, dances, trains二)在x, sh, ch, s, tch后加es。
如:watches, washes, wishes, finishes三)1)以辅音字母加y结尾的变y为i再加es。
一般现在时讲解1. 一般现在时的概念一般现在时表示经常的、习惯性的动作或存在的状态。
2. 一般现在时的构成一般现在时的构成主要有两种形式:(1)be型:句子的谓语动词只有be(am,is或are):a.肯定句中,只出现be,如:I am a student.我是一名学生。
b.否定句中,要在be后面加not,如:She isn't a teacher.她不是教师。
c.一般疑问句,要将be放在句子开头(注意句首字母大写),句尾用问号,答语用Yes,主语+be.或No,主语+be+not.如:—Are you ready?—你准备好了吗? —Yes,I am.—是的,我准备好了。
(—No,I'm not.—不,我没准备好。
)(2)实义动词型:句中的谓语动词为实义动词(也叫行为动词):a.肯定句中,只出现实义动词,如:I get up in the morning.我早晨起床。
b.否定句中,要在实义动词前面加do(does)+not,do(does)作助动词,本身无意义,常与not缩写成don't(doesn't),如:I don't like vegetables.我不喜欢蔬菜。
c.一般疑问句,要在句子开头加助动词Do(does),句尾用问号,简略答语用Yes,主语+do(does).或No,主语+do(does)+not.如:—Do you like oranges?—你喜欢桔子吗?—Yes,I do.—是的,我喜欢。
(—No,I don't.—不,我不喜欢。
)3.一般现在时的用法1) 经常性或习惯性的动作,常与表示频度的时间状语连用,如:always, often, usually, every day, sometimes等。
I leave home for school at 7 every morning. 我每天早上7点去上学。
2) 客观真理,客观存在,科学事实。
