1、可数与不可数名词 寒假专题二：名词数的表达 二. 重点、难点： 语法详解：不可数名词及可数名词数的表达 三. 具体内容： 重难点解析： 英语表达数目和数量的特别方法 不可数名词没有表示复数的“s”标志，因此前面不可有数目字，只可以有数量词。例如我们可以说，不可以说： There is not much furniture in the office. There are not many furnitures in the office. 这是不是说不可数名词就不可数呢？不然。相反的，不可数名词也是可数的，主要方法是借助单位词，如： a piece of，a cup of，a drop of，
2、a lump of，a handful of，a flash of，a blade of，a head of，a bar of，an ear of等。 如果数目超过“一”，就以确实数目取代“一”。例如： two pieces of，three cups of 和 five lumps of 等。 现在试试把上述这类单位词和适当的不可数名词连用。 Mr. Li has just bought a piece of new furniture. Give me a cup of cold water，please. Please put two lumps of sugar in my coffe
3、e. The boy picked up two handfuls of sand from the beach. We saw a flash of lightning in the sky. The gardener pulled out blades of wild grass from the garden. She gave bars of chocolate to the visiting children. 有些名词如 scissors，trousers，spectacles，tongs，pliers 等，都以复数形式出现，如： The scissors are lying on
4、 the table. The spectacles fit me nicely. 如果要给这些名词表示单数“一”的意思，就要借重单位词了。例如： Mary has just bought a pair of scissors. 11 The mechanic repaired the machine with a set of pliers. 现代英语注重简洁，合成形容词便应运而生，其中有一种是用来表示数目的，方法是： “数目+名词”，如：a fiveyear plan，a tendollar note，a twohour meeting，a threeday conference等。 必须
5、注意的是，这种合成形容词中的名词，只能以单数形式出现。如果用复数，就错了，如： a fiveyears plan，a tendollars note，a twohours meeting，a threedays conference. 这类错误，虽然频率不是很高，但也是要留意才好。 如果没有把握，不妨用完整的表达方式，如： a fiveyear plana plan of five years a tendollar notea note of ten dollars a threeday conferencea conference of three days 等。 可数名词和不可数名词 一
6、、名词：名词是所有事物的名称，包括人、物及抽象概念。名词分为普通名词和专有名词两大类。名词在句子中作主语，宾语或表语等。 1. 普通名词 普通名词是某类人、事件、物体和抽象概念的名称。根据所指代物体的特征，普通名词又可分为以下四类： A. 个体名词： 表示人或物体中可以数清的个体。如：student、pen、bird等。 B. 集体名词： 表示由个体组成的集合体。如：people、police、family等 C. 物质名词： 表示构成物体物质的不可数名词，或表示无法分为个体的物质的名词。如：water、air、wood等。 D. 抽象名词： 表示动作、状态、品质、情感等非具体化的抽象概念。如
7、：work、peace、love等。 2. 专有名词： 专有名词是某些人、事物、机构、组织等特有的名称。主要包括：人名、地名、国名、党派名称等。如：Churchill、Tokyo、China等。 二、可数名词和不可数名词。 1）可数名词： 一般来说个体名词和集体名词可以用数目来计算，称为可数名词。可数名词有单数和复数两种形式。 例如： a book, two books, a student, three students, a family, many families。 名词单数变复数变化如下： 1. 词尾直接加s如： catcats bagbags daydays 2. 以s, sh,
8、ch, x 结尾的词加es 如： classclasses matchmatches box boxes dish dishes 3. 以辅音加y结尾的词变y为i, 加es. 元音加y结尾的词直接加s, 如：partyparties citycities storystories boyboys monkey monkeys key keys 等。 4. 以f或fe结尾的词, 变f或fe为v, 加es,如： wife wives half halves 注意特殊情况直接加“s”，要逐个记 chiefs, handkerchiefs, roofs. 5. 以辅音加o 结尾的词常加es, 如：to
9、matoes, potatoes, heroes. 元音加o结尾直接加s. 如：radios, zoos, pianos. 特殊情况：photos 6. 名词单数变复数特殊变化也要逐个记。如： manmen, womanwomen, toothteeth, goosegeese, footfeet, childchildren, mousemice 2）不可数名词 不可数名词不能用数字计算。包括物质名词及抽象名词等。所以它通常只有单数形式。如：English, air, water, cotton, work 不可数名词表示数量时，可以用量词来表达其结构是数词+量词+of+名词。如：a bot
10、tle of water, two cups of tea, three pieces of paper 注意事项： 1. 不可数名词没有复数变化，不能用a，an，但可用the，或不用冠词，如：Bread is the usual breakfast. 2. 虽然不可数名词没有复数变化，但量词超过一时要加复数。 如：three cups of coffee, five bottles of water 3. 有量词修饰时注意名词是否可数，不可数时用单数，可数时用复数，如：ten bags of rice ten baskets of eggs 1. 英语句式要在主语、谓语上保持数的一致。 1）
11、These are new_. A. book B. a book C. books D. / 注：名词的复数形式及其发音。 可数名词的复数形式一般在单数形式后+s , 清辅音后的s读/s/, 浊辅音或元音后的s 读/z/. mapmaps /s/ friendfriends /z/ radioradios /z/ 在s,x, ch, sh结尾的词后+es , 此es读/iz/ foxfoxes busbuses boxboxes wishwishes watchwatches classclasses 在以辅音字母+y的词后，把y变成 i ，再加es, 此es读/iz/;元音字母+y结尾的词
