小学英语知识点总结

1、可数名词名词可分为可数名词和不可数名词两部分。其中，可数名词是表示能够计算的人或物的名称，他们通常有单数和复数的形式。单数通常用 a,an 或者是 one 来表示。 an 用在元音字母的前面。 如：a desk, an apple, oneboy.·可数名词的变化规则1、直接在单词的后面加-s.photo-photos village-villages hand-handsbook-booksegg-eggsstudent-studentscloud-cloudsflower-flowersmap-mapsgirl-girlspen-pens2、如果单词以s,x,ch,sh结尾，通常

2、要在单词后面加-es.bus-busesclass-classes box-boxdress-dresses peach-peacheswatch-watchesfish-fishes3、以辅音字母+y 结尾的单数名词要把y 变为i，再加 -es.如果y 的前面是元音字母，则直接加上 -s.family-families story-stories baby-babies day-days toy-toys boy-boys4、以 f,fe 结尾的单词，要把 f,fe 变为 v，再加 -es.knife-knives wolf-wolves shelf-shelves5、以-o 结尾的名词，如

4、nts, boots, glasses等。1II .不可数名词1. 一般来说，不可数名词主要是以物质名词与抽象名词为主。它们通常没有复数形式，也不能与 a ,an 连用。在表示“一”或“几”的数量概念时，不可数名词必须与相应的量词连用。如果时表示复数的数量关系时，则把量词变化，不可数名词不变。修饰不可数名词的数量词语有： some, any, much, a lot of, a little等。例如： a box of milk 一盒牛奶somewater 一些水much food 大量的食物a little time一点时间2. some 与 any 词语辨析some 与 any 都表示“一

5、些”，但它们的用法不同。 some 用在肯定句中。而 any 用在否定句与一般疑问句中。 同学们要特别注意的是： some 还可以用在客气请求的一般疑问句中。例子： I have some beautiful stamps（.肯定句）I donthave any beautiful stamps.（否定句）Do you have any beautiful stamps?（一般疑问句）A: Can I have any some bananas?B: Sure（.客气请求的一般疑问句）3. many ,a lot of ,much 词语辨析many ,a lot of ,much ,这三个词都

6、是表示“许多” 。many 是用来修饰可数名词 , much 用来修饰不可数名词， a lot of 则用来修饰可数与不可数名词。例子： Peter has many friends （.可数名词的前面）Peter has much food for his birthday party. （不可数名词的前面）Peter has a lot of friends. （可数名词的前面）Peter has a lot of food for his birthday party. （不可数名词的前面）·不可数名词的归类1、表示液体： water, juice, milk, coffee,

18、s 的用法区别及练习1. 由连系 am， is， are 构成的句子：变一般疑问句时把am， is，are 提到句子的前面，句尾用问号即可。变否定句时直接在am， is，are 后面加 not 即可。例如：肯定句 :He is a student.一般疑问句 : Is he a student?否定句 : He is not a student.画线提问 : 对 he 提问 : Who is a student?对 a student 提问 : What is he? or What does he do?2. 由情态动词 can, may, should 等构成的句子 :变一般疑问句时把ca

19、n,may,提到句子的前面,句尾用问号即可.变否定句时直接在can,may,后面加 not 即可 .例如 : 肯定句 : She can swim.一般疑问句 : Can she swim?否定句 : She can not swim.画线提问 : 对 she 提问 : Who can swim?对 swim 提问 : What can she do?3. 由行为动词构成的句子 :需要加助词do 或 does. 变一般疑问句时把do/does 放在句子前面.变否定句时把don t/doesn t 放在动词的前面。要注意观察动词的形式并对号入座。一般疑问句和否定句的动词三单式都要变回原型。例如

20、: 肯定句 : They play football after school.He plays football after school.一般疑问句 : Do they play football after school?Does he play football after school?否定句 : They don't (do not) play football after school.He doesnt play football after school.画线提问 :对 they/he 提问 : Who plays football after school?Who

21、plays football after school?对 play football 提问 : What do they do after school?What does he do after school?对 after school 提问 : When do they play football?When does he play football?注意： 1.在改疑问句时，遇到主语人称是第一人称I、 we 的需要将人称换成第二人称you2.在改疑问句和否定句中，遇到some 和 and，将其改为any 和 or.按要求改写句子：1.I know the answer.( 一般疑问句

22、 )_ _ _the answer?2.We can see some birds.( 一般疑问句 )_ _ see _ birds?3.He designs clothes.( 一般疑问句 )_ he _ clothes?4.There are some flowers on the teachers desk.(一般疑问句 ) _ _ _ flowers on theteachers desk?5.There are some apples on the tree.( 否定句 ) There _ _ _ apples on the tree.6.I think he is very old

You should add water often. （一般疑问句）_ _ _ water often?6一般疑问句一、什么是一般疑问句1.定义：用Yes或 No 作答的疑问句叫一般疑问句。2.

25、特点： 1、以 be 动词、助动词或情态动词开头；eg: Is your father a teacher?Does Catherine like animals?Can Jenny speak French?2、往往读升调；3、译成汉语，都可以带上“吗”eg: 上面三句可分别译为：你父亲是老师吗？凯瑟琳喜欢动物吗？詹妮会说法语吗？二陈述句和一般疑问句间的转换要将陈述句变成一般疑问句，可以遵循下列步骤：1.看句中有没有 be 动词（ am、 is、 are、 was、 were ）助动词（ do、 does、did、 have、 had）或情态动词（ can、 must 、 will 、 ma

26、y 等），如果有，将其提到句首，句末打上问号即可。eg:It was rainy yesterday. Was it rainy yesterday?Tom'sfather can play the piano. Can Tom's father play the piano?I have finished my homework. Have you finished your homework?2.如果句中没有be 动词、助动词或情态动词，则根据谓语动词的形式借助do 的相应形式放在句首。具体方法是：如果谓语动词是原形，则借do；如果谓语动词是一般现在时第三人称单数形式，则借

27、does；如果谓语动词是过去式，则借did. 需要注意的是，借does 或 did 后，原句的谓语动词要变回原形。eg： They go to school by bike. Do they go to school by bike? Bill gets up at 6:30 every day. Does bill gets up at 6:30 every day? The students saw a film yesterday. Did the students see a film yesterday?陈述句变一般疑问句应注意的事项陈述句变成一般疑问句除了遵循上述规则以外，还应注意

28、下列几点：1.如果陈述句中有第一人称，则变问句时最好要变为第二人称。eg： I usually have lunch at school. Do you usually have lunch at school? My father is playing soccer. Is your father playing soccer?2.如果陈述句中有some, 则变问句时往往要变成any 。eg： There is some water on the playground. Is there any water on the playground?3.复合句变一般疑问句通常只变主句，从句不变。e

29、g： I know he comes from Canada. Do you know he comes from Canada?7三 .一般疑问句往往采用简短回答由三部分（三个单词）组成，对这三部分（三个单词）的确定可以概括例下：1.第一个词：不是Yes就是 No。（有时根据语气的不同，Yes可由 Sure, Certainly, Of course 等代替 .NO 可由 sorry 代替 .）2.第二个词：问谁答谁。即答语中的主语须与问句的主语一致（但必须用主格代词）。eg： Does she clean her room every day? Yes, she does.Is Anna

30、s father a doctor? No ， he isn t.如果主语是this that, 回答时用it 代替，如果问句中主语these, those,回答时用they 代替。3.第三个词：用什么问，用什么答。即沿用问句中的引导词。Can Jim play soccer? Yes, he can.Does Mr Bean speak English? Yes, he does.需要注意问题： （ 1） .用 may 引导的问句，肯定回答用may，否定回答用 can t 或 mustn t用 must 引导的问句，肯定回答用 must，否定回答用 needn t.eg：May I go t

31、o the park now?Yes, you may. /No, you mustn t. Must I wash my clothes now?Yes, you must. /No, you needn t.4用 No 开头作否定回答时,结尾要加上not 。因为回答必须是三部分，所以否定回答必须缩写，而肯定回答不能缩写。eg:Did Thomas come here yesterday?Yes, he did./ No ,he didn t.Is Lin Lin in Class 3?Yes, she is. / No, she isn t. 或（ No, she s not） .83、英

40、e be 就近原则） There is a bird in the tree. 树上有一只鸟。 There is a teacher and many students in our classroom. 我们教室里有一位老师和许多学生。 There are two boys and a girl under the tree. 树下有两个男孩，一个女孩。3. There be 句型与 have 的区别：(1) There be 句型和 have 都表示“有”的含义。区别如下： There be 表示“某处存在某物或某人”；have 表示“某人拥有某物/ 某人”，它表示所有、拥有关系。He h

41、as two sons.他有两个儿子。There are two men in the office.办公室里有两个男人。(2)当 have 表示“包括” 、“存在”的含义时，There be 句型与其可互换。例如：A week has seven days. =There are seven days in a week. 一个星期有七天。变脸一：否定句There be 句型的否定式的构成和含有be 动词的其它句型一样，在be 后加上 not.。There are some pictures on the wall. There aren't any pictures on the

42、wall. =There are no pictures on the wall.There is a bike behind the tree. There isn't a bike behind the tree. =There is no bike behind the tree.变脸二：一般疑问句There be 句型的一般疑问句变化是把be 动词调整到句首，再在句尾加上问号即可。There is some water on Mars.
