2、的特征、状态，这种情形下，通常不带时间状语。如：She likes bread, but she doesnt like pizza .Do you speak English?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.Walls have ears. 隔墙有耳。

3、（四）表示将来。如：1.表示按时间表拟定的或安排好的到了时间就会发生的事情或动作：The train arrives at 10:30 .There is still plenty of time. 火车10:30才会到达，还有足够多的时间。She comes back next week .她下周就会回来的。2在时间状语从句中和条件状语从句中代替一般将来时.I will give you some candy when we meet next week.If he arrives ,please give me a phone call .二、一般现在时构成：（一）含有be动词的一般现在时

4、；This is a red skirt. This is a T-shirt. Its redThese are trousers. Theyre black.The trousers and the T-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 are 2. 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；（三单：“不是你，不是我，只有一个！”一般现在时时才变化）比如：He、 sh

5、e、 it、 Li Ming 、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am 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Thes

6、e 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”，别的地方就只用动词原形就可以了。（三单：“不是你，不是我，只有一个！”一般现在时时才变化）举例：I like the shirt a

7、nd 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.

8、r 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（含有情态助动词）。情态助动词： can 1)否定句：主语+ be动词（情态动词） + not +其它。如：He is a worker. He is not a

9、worker.I can show you. I cant 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 isnt.I can show you. I cant show you .Can you show me ?Yes ,I can. No , I cant.I am a student . I am not a student .Are you a student?

No ,they arent.（二）含有实意动词的句子1.否定句：主语+ dont( doesnt ) +壮语+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doesnt；（2） 主语+ dont( doesnt)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doesnt构成否

11、定句。主语+doesnt/ I dont+动词原形（动词原来形状）如：He doesnt often play.I dont 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 )”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, I dont.如：- Does she go to work

12、 by bike?肯定形式回答：Yes, she does. 否定回答： No, she doesnt.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：

13、 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 ,Im not . My father is 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 isnt（4）在一般疑问句和否定句中，要表达“一些”时 ，someany；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 t

14、ea in the cup?Do you have any children?May I have some fish?Would you like 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 foo

15、tball on Friday afternoon.When do you usually play football ? I usually play 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

16、后读z。如：helphelps knowknows getgets readreads2.以字母s，x，ch，sh或有些以字母o结尾的动词加-es，guessguessesgAfixfixes teachteaches washwashes brush-brushes注意：gogoesEdodoes3.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，carrycarries，flyflies2）字母y前为元音字母，第三人称单数形式直接在动词后面加-s。 playplays saysays举例说明：1.
