What is a material noun? Countable?

Material nouns are defined as objects that have a specific existence but are uncountable but have a fixed shape (such as gases, liquids, powdery or fine-grained objects, materials, block shaped objects, etc.). The precautions for using material nouns are as follows:

(1) Material nouns are uncountable nouns, so they are not prefixed with "a (an)" or plural. Example: Do you like to have an awater? Do you want to drink some water? - Remove or change "a" to "some". ）Example: Insulmerwedrinkmanywater. (×) (We drink a lot of water in summer. - Change "manywater" to "much (alotof) water". ）(2) The quantity of material nouns can be expressed in the following two ways. (a) Quantity: much, plentof, Agreatdealof (many), alotof (=lotsofs) (many), some (some), alittle (a little - indicating affirmation), little (a little - indicating negation), no (no), etc. (b) Unit: measured according to its actual usage or container, weight, or shape, for example: a bottle of water, an ounce of gold, an ounce of gold, an pound of beef, aloafofbread, a loaf of bread. Common substance terms for bread: 1. Gas: air, gas, smoke, steam The most commonly used units of measurement for gases are "m3" (cubic meter) or "ft.3" (cubic foot/foot). Example: 1m3 of gas costs only 65dintheU.S. ）2. Liquids: water, oil, tea, coffee, wine, beer [bi+] (beer), milk, coke [kouk] (Coca Cola), gasoline (gasoline), etc. The commonly used liquid measurement methods are as follows: cc=cm3 (cubic centimeter [cm]) lite=1000cc (liter) gallon=4liters (gallon) or weight such as kilograms (kg.), tons (ton), etc. Example: Mynewcarruns45kmagallon (of gasoline) (my new car can run 45 kilometers per gallon of gasoline). ）3.

d or fine-grained items: flour, salt, sugar, rice, sand, etc. The unit of measurement for powdery or fine-grained items is usually a container or weight. Example: Theysellflorbythesack [s $k]. (They sell flour in bags.). ）Note: Rice can be measured in "grains", but in daily life, such as how much rice to buy or how much rice a family of five needs for two meals a day to cook, it is obviously impossible to use "grains" to measure. This is why "rice" is classified as a material noun. But sometimes we say that a person is good at writing fine characters and can write twenty words on a grain of rice. At this point, one grain of rice is the correct expression, and its English name is grain of rice . For example: Heateupe very grain of rice. He ate every grain of rice. ）4. Block shaped objects (products): Common block shaped objects (products) can be further distinguished as follows: (a) Food: bread (bread), Butter, chocolate, meat, etc. (b) Daily necessities: chalk, paper, money, soap, etc. (c) Minerals: copper, gold, iron, silver, etc. (d) Raw materials/materials: brick, clay, cloth The measurement of block shaped objects is based on their actual usage habits, such as cotton, earth, glass, stone, wood, wool, etc. Abstract nouns are the names of properties, states, concepts, actions, etc.

1. Countability and uncountability of nouns (1) When learning nouns, there is a particularly important issue - the countability and uncountability of nouns. In fact, both countable and uncountable nouns belong to ordinary nouns. Countable nouns refer to people or things that can be counted in numbers and divided into individuals; Therefore, it has a plural form, and when its plural form is used as the subject in a sentence, the predica
