1、小学英语语法集训之一:第一课 名词I. 名词分类：可数名词 不可数名词1、 名词分为可数名词和不可数名词。不可数名词数不清（没有复数）例如：drink milk tea water orange juice coke coffee porridge food rice bread meat fish fruit cake dumplings 2、可数名词单数前面加不定冠词a(an)，表达一种，有复数形式，表达复数概念，不可数名词不能与不定冠词a(an)连用，没有复数形式many“诸多”+可数名词复数much“诸多”/a little “一点”+不可数名词some, any , a lot of

2、 (lots of) 两者都可以修饰。3、可数名词可以直接用数词来修饰不可数名词表达数量时需要用 数词 +量词 +of + 名词对可数名词的数量提问用how many 对不可数名词的数量提问用 how much 4、不可数名词的量有如下两种表达措施：1） some, much ,a little ,a lot of ,a bit of , plenty of 用等表达多少。注意既可以与可数名词复数，又可以与不可数名词连用的有：plenty of ,some ,a lot of ,lots of ,most of 等。例：There is much water in the bottle. Il

3、l tell you much good news.we should collect some useful information. 2）用单位词表达。用a . of 表达。如a cup of （一杯.），a bottle of （一瓶.）a piece of （一张.），a pair of shoes（一双鞋）如two cups of tea（两杯茶）,five pieces of paper（五张纸）注意单位词后的动词单复数形式往往取决于单位词的单复数形式；千、百等数词与名词加用，表达复数时，数词仍保持单数，名词变复数。如two hundred students（200名学生）ten

4、thousand trees（10000棵树）考点He caught a lot of fish她抓到了许多鱼（此处为许多条鱼，fish的复数仍为fish）5、可数名词分为单数和复数。名词单数就是该词自身，在其前面加a或an。1）单数如a desk（一张桌子）an old desk（一张旧书桌）2）复数：要表达一种以上概念时，要用名词复数形式规则变化1）一般状况下加-s如bookbooks, deskdesks, cat-cats, bed-beds2）以s ,x ,ch , sh结尾加-es如boxboxes, busbuses, brush-brushes, watch-watches 注

5、意以th结尾加-s, month-months stomach-stomachs 3)以辅音字母+结尾，变y为i再加- es。如city-cities(都市) country-countries(国家) 注意以元音+y，直接加s。如：day-days(天)，boy-boys(男孩) 4)以f或fe结尾，复数变f或fe为v再加-es如knife-knives(书) , half-halves(一半) (thief ,wife ,life ,shelf ,knife ,leaf ,self ,half ,wolf) 注意有少数词后直接加s，如roof-roofs (屋顶) 5)以o结尾(1)辅音字

6、母加o结尾名词的加-es如tomato-tomatoes(西红杮) potato-potatoes(土豆) (2) 元音字母加o结尾名词的加-s 如piano-pianos (钢琴), zoo-zoos(动物园) photo-photos (照片), kangaroo-kangaroos(袋鼠) kilo-kilos(公斤)注意zero 两种方式都可：zero-zeros或 zeroes(零) 不规则变化1) 元音字母发变化。如man-men(男人) ， woman-women(妇女) tooth-teeth(牙齿) ， foot-feet(脚) mouse-mice(老鼠) ， police

7、man-policemen(警察) policewoman-policewomen(女警察) 2) 词尾发生变化。如child-children(小孩) ， ox-oxen(公牛) 3) 单、复数形式相似。如fish-fish(鱼) ，sheep-sheep(绵羊) ，deer-deer(鹿) ，Chinese-Chinese(中国人) ，yuan-yuan(元) ，jinn-jinn(斤) 注意不说an English，要说an Englishman. fish作鱼肉讲时不可数，没有复数。fishes指多种不同种类鱼或指几条鱼。4) 形似单数，实为复数意义。如people(人，人们)thes

8、e people (不说a people，可说a person) police(公安，警察)ten police (不说a police，可说a policeman) 5) 由man和woman构成的合成名词，变复数将名词及man或woman都变成复数。如a man driver-men drivers(男司机) a woman doctor-women doctors (女医生) 6) 合成名词变为复数时，一般只将里面所含的主体名词变为复数。如passer-by-passers-by(过路人) bus driver-bus drivers(汽车司机) 注意如果没有主体名词，就在最后一词上加-

9、s。如：grown-up-grown-ups(成年人) letter-box-letter-boxes (信箱) 注意hair和fruit一般作单数，表达总体。若表达若干根头发或若干种水果，则需用这两个词的复数形式。如would you like some more fruit? 你要不要再吃点水果？we bought a lot of fruit from the market. 我们从市场上买了许多水果，china has some good frits. 中国有某些好的水果。(指种类) she has a few white hairs. 她有几要白头发。his black hair i

10、s going white. 她的黑发逐渐变成灰白色。注意wind ,snow和rain此类词，有时也可以有复数形式，表达多次的风、雪或雨。注意以boy 和girl开头的复合名词变成复数时，一般只把后一名词变成复数。如 boy student-boy students(男学生) girlfriend-girlfriends(女朋友) 7) 有些名词只有作复数。如scissors(剪刀) a pair of scissors(一把剪刀)trousers(裤子); shorts(短裤); jeans(工装裤); scales(天平), sunglasses(太阳镜);名词+man(woman)构成

11、的复合名词，其复数形式一般与简朴名词同样，即把man(woman)改成men(women)。如Englishman-Englishmen(英国人) Frenchwoman-Frenchwomen(法国妇女) 注意German不是复合词，它的复数是Germans。练习：一 写出下列名词的复数形式1. this _ 2. watch_ 3. child _ 4. photo _ 5. diary _ 6. day _ 7. foot _ 8. dress _ 9. tooth _ 10. sheep _ 11. box _ 12. peach_ 13. sandwich _ 14. man _ 1
