1、一般现在时基本用法 介绍：一、一般现在时的功 能：（一）表示经常性发生 或反复发生习惯性的 动作；这种用法中经常用到： often 经常,usually 通 常,always 总是， every 每 个 , sometimes 有时， at在几点钟，等做时 间状语，也可以说，这是 一个一般现在时语法 的特征。如：I usually get up at six.（表示经常性的事 情。）He often has dinner at home.（经常性事情）They always go to school on foot.他们 总是步行去上学。（“总 是”表示经常性的事 情）（二）表示事物或人物 （

2、主语）的现在的特征、状态，这种情形下， 通常不带时间状语。如：She likes bread, but she doesn ' t like pizza .Doyou speakEnglish?The sky is blue.天空 是蓝色的。He works in a big company. 他在一家大 公司工作。（三）表示客观现实、 客观真理、科学事实、格言等； 如：The earth goes around the sun.地球 绕着太阳转。There are four seasons in a year.The sun always rises in the east.Wall

4、.二、一般现在时构成： （一）含有be动词的一般现在时；This is a red skirt.This is a T-shirt. It's red .These are trousers.They're black.The trousers and theT-shirt are nice.This is the way I read a book, on a Tuesday Morning .小贴士：1. Be动词：也就是：am is are2. am 用在第一人 称：“ I ”后面；3. is的用法：(1 ) is 用在 he she it 等第三人 称单数的主语后面；(

5、三单：“不是你，不 是我，只有一个！” 一 般现在时时才变化) 比如：He、 she、 it、 LiMing 、Xiao Hong 、 this、that 以及 this、that修饰的部分后面等等，但是 Li Ming and Xiao Hong 这就不是 第三人称单数了，而是复数应该用：are(2)不可数的名词做成分用到be动词时也 要用：is3. are的用法：(1)第一人称复数：we ；(2 )第二人称即： you(单数、复数的后 面)；(3)第三人称复数 they 后面、 以及 these , those或 these , those 修 饰的部分等，表示复数 的地方也就是说：记住a

6、m is应该用的地方就可以 了，别的地方都是用的are。This is a dress.This is这是These are socks.These are 这些是These are new shorts.This is a new dress.These are his shoes?This is her skirt.The trousers are nice.The trousers and the T-shirt are nice.（二） 不含有be动 词，即含有实意动词的 一般现在 时；这里只有一个需要记 住的地方：就是第三人 称单数的后面，动词要加“ -s” 或“ -es ”，别的地

7、方 就只用动词原形就可 以了。（三单：“不是你，不 是我，只有一个！” 二 般现在时时才变化） 举例：I like the shirt and the skirt.In the evening, I do my homework.In the evening, he does his homework.In the evening, she does her homework.In the evening, they do their homework.In the evening, Su Hai and Su Yang do their homework.In the evening, Su

8、 Yang do his homework.In the evening, the girls/ the boys do their homework. 二、一般现在时句子的 变化：否定句、疑问句, 特殊疑问句，其中特殊疑问句放在后面介绍。否定句：简单来说，就是表示否定的句子。一般疑问句：一般疑问句是疑问句的一种。它 是只用yes （是）或no （否）来回答的句子。特殊疑问句：以特殊疑 问词开头，对句中某一成分提问的句子叫特 殊疑问句。常用的疑问词有：what、who、whose 、 which 、when 、 where 、 how 、why 等。（一） 含有be动词 的一般现在时的 变化（

9、含有情态助动词）。情态助动词：can1）否定句：主语+ be 动词（情态动词） + not +其它。如： He is a worker.He is not a worker.I can show you. I can ' t show you .2） 一般疑问句：将be动词（情态动词）提到 句子前面即可，即：Be （情态动词）+ 主语+ 其它。He is a worker.He is not a worker.Is he not a worker?Yes , he is. No , he isn ' t.I can show you. I can ' t show yo

10、u .Can you show me ?Yes ,I can. No , I can t.I am a student . I am not a student .Are you a student? 肯定回答：Yes, I am./否定回答：No, I'm not.These are my friends . They are not my friends.Are they your friends ?Yes , they are . No ,they aren ' t.(二)含有实意动词的 句子1 .否定句：主语+ don't( doesn't ) + 壮

11、语+动词原形(+其它、 时间或地点壮语)。这里需要记住几点：(1)主语“三单”时, 要用助动词 doesn't ;(2)主 语 + don't( doesn't) 后面要加动词原形，即：去掉三单时动词后面的(s或es)。当主语为第三人称单数时，要用doesn't构成否定句。主语 +doesn't/ Idon't+动词原形(动词原来形状)如：He doesn't oftenplay.I don't like bread.2 . 一般疑问句：Do( Does ) + 主语 +壮语+动词原形+其 它。这里的 “ Do( Does ) ”

12、只是为了帮助形成一般疑问句，没有实际意 思！这里需要注意几点：(1)当主语为第三人称单数时，要用 does替换do构成一般疑问句。(2)主语三单时，句 子中的动词要变 为动词原形。如：-Do you often play football?肯定形式：Yes, I do.否定形式：No, Idon't.如：-Does she go to work by bike?肯定形式回答：Yes, she does. 否定回答：No, she doesn't.3 .小贴士：(这里是平 时我们注意积累的地 方，可以把我们平时的 积累、感悟记在这里！)(1) “含有be动词的 一般现在时”这里句

13、 型的变化上边已经说过，但是并不局限于一 般现在时！更为准确的 表达是：含有be (am、 is、 are、 was、 were )动词的句子，将 其提到句首，句末打上 问号即可；(2) 一般疑问句的回 答，开头往往是yes或no 。也就是说，只要能看出 是一般疑问句，那么它 的回答开头往往就是 yes 或 no ;(3)如遇第一人称， 最好将其变成第二人 称；举例：I am a teacher.否定句： I am not a teacher.一般疑问句：Are you a teacher?肯定回答：Yes , I am . 否定回答：No ,I' m not .My father i

14、s a teacher.否定句：My father is not a teacher. 一般 疑问句：Is your father a teacher?肯定回答：Yes ,he is . 否定回答：No ,he isn ' t(4)在一般疑问句和 否定句中，要表达“一 些”时，some f any ; 但是，如果这个问句是 用来表达“建议、请 求、邀请”等交际功能 时，而且希望听到肯 定回答时，应该用some.Is there any tea in the cup?Do you have any children?May I have some fish?Would you like

15、some tea?Shall we buy some vegetables?Can I borrow some money from you?Why not have some bread?How about some orange juice?（三）特殊疑问句： 构成：疑问词+一般疑 问句，同时注意去掉划 线部分。如：Where is my bike?How does your father go to work?I usually play football on Friday afternoon.When do you usually play football ?I usually p

16、lay football on Friday afternoon.What do you usually do on Friday afternoon?Who is singing?Who often helps your mother?（四）一般现在时中,动词+s的变化规则即： 动词三单的变化规律：（三单：“不是你，不 是我、只有一个！” 一 般现在时时才变化） 动词第三人称单数词 尾变化有三种形式。1 .一般动词在词尾加-s , -s在清辅音后读/ s/,在浊辅音或元音 后读/z/。如：help helps know knows get getsread reads2 .以字母 s, x,

17、 ch, sh 或有些以字母o结尾的 动词加-es ,guess guesses?fixf fixes teach fteaches wash f washes brush-brushes注意：go goes?dodoes3 .以字母y结尾的动 词，有两种情形：1）以辅音字母+y结尾 的动词，先变y为i, 再加-es ,carry carries , fly f flies2）字母y前为元音字 母，第三人称单数形式 直接在动i后面加-s。play plays say 7 says举例说明：1.
