A few examples:

• Objects with a definite shape: a building, a balloon, a house, an octopus, four buildings, six balloons, four houses, two octopi
• Units of measurement and words of classification: a gram, a pound, a piece, a lump, an item, a bit, a family, a state, a language, a phrase, a word
• Some abstract words: a hindrance, a scheme, an idea, a plan, a taboo, a rest

• They have singular and plural forms.

物质名词(不可数名词)

Mass nouns are uncountable by a number. Mass nouns are quantified by a word that signifies amount.

物质名词是数字不可数的。

几个例子:

• Materials, food, metals, and natural qualities: bread, cotton, wood, lightness, adolescence
• Names of liquids, gases, and substances made of many small particles: cappuccino, oil, smoke, oxygen, rice, sugar, salt, cement, gravel
• Names of languages: English, Spanish, French, Latin, Sanskrit, Chinese
• Most gerunds: looking, listening, swimming, running, anticipating

请记住，数字不能用于量化物质名词。 不正确： four woods, one rice, three courages (四个树林，一个米饭，三个勇气).

To measure or classify mass nouns, use "of" after a measurement: a foot of wood, a pound of rice, an ounce of courage, a bar of chocolate, a piece of music, a bag of money

Tests for Mass Nouns:

• Mass nouns are quantified by an amount rather than a number.
• They have only one form (singular).
• They cannot have "a," "an," or "one" before them as modifiers.
• They can use "much" as a modifier.
