Help the spaceship captain log the emergency damage report by dragging the correct terms to the blanks.

We sustained a huge amount of damage to the outer hull, and we have very few tools left to fix it. We will need to use less energy in the living quarters until we reach the starbase.

We sustained a huge amount of damage to the outer hull, and we have very few tools left to fix it. We will need to use less energy in the living quarters until we reach the starbase.

Quantifiers must match the countability of the noun they describe.

Damage is uncountable, so we use "amount" (not "number", which is for countable nouns).

The phrase "very few" requires a plural countable noun, making tools the only correct choice ("equipment" and "machinery" are uncountable).

Energy is uncountable, so we must use less rather than "fewer".

Count Nouns

In linguistics, a count noun (also countable noun) is a noun that can be modified by a numeral) and that occurs in both singular and plural forms, and that co-occurs with quantificational determiners like every, each, several, etc. A mass noun has none of these properties, because it cannot be modified by a numeral, cannot occur in plural, and cannot co-occur with quantificational determiners.

Examples

Below are examples of all the properties of count nouns holding for the count noun chair, but not for the mass noun furniture.

Occurrence in plural/singular.

  • There is a chair in the room.
  • There are chairs in the room.
  • There is chair in the room. (incorrect)
  • There is a furniture in the room. (incorrect)
  • There are furnitures in the room. (incorrect)
  • There is furniture in the room.

Co-occurrence with count determiners

  • Every chair is man made.
  • There are several chairs in the room.
  • Every furniture is man made. (incorrect)
  • There are several furnitures in the room. (incorrect)

Some determiners can be used with both mass and count nouns, including "some", "a lot (of)", "no".

Others cannot: "few" and "many" are used with count items, "little" and "much" with mass. (On the other hand, "fewer" is reserved for count and "less" for mass, but "more" is the proper comparative for both "many" and "much".)

Mass Nouns

In linguistics, a mass noun, uncountable noun, or non-count noun is a noun with the syntactic property that any quantity of it is treated as an undifferentiated unit, rather than as something with discrete subsets. Non-count nouns are distinguished from count nouns.

In English, mass nouns are characterized by the fact that they cannot be directly modified by a numeral without specifying a unit of measurement, and that they cannot combine with an indefinite article (a or an). Thus, the mass noun "water" is quantified as "20 litres of water" while the count noun "chair" is quantified as "20 chairs". However, both mass and count nouns can be quantified in relative terms without unit specification (e.g., "so much water," "so many chairs").

Some mass nouns can be used in English in the plural to mean "more than one instance (or example) of a certain sort of entity"—for example, Many cleaning agents today are technically not soaps, but detergents. In such cases they no longer play the role of mass nouns, but (syntactically) they are treated as count nouns.

Some nouns can be used indifferently as mass or count nouns, e.g., three cabbages or three heads of cabbage; three ropes or three lengths of rope. Some have different senses as mass and count nouns: paper is a mass noun as a material (three reams of paper, two sheets of paper), but a count noun as a unit of writing (the students passed in their papers).

Collective Nouns

Collective nouns are nouns that – even when they are inflected for the singular – refer to groups consisting of more than one individual or entity. Examples include committee, government, and police. These nouns may be followed by a singular or a plural verb and referred to by a singular or plural pronoun, the singular being generally preferred when referring to the body as a unit and the plural often being preferred, especially in British English, when emphasizing the individual members. Examples of acceptable and unacceptable use given by Gowers in Plain Words include:

  • A committee was appointed to consider this subject. (singular)
  • The committee were unable to agree. (plural)
  • The committee were of one mind when I sat on them. (unacceptable use of plural)

Singulars and Plurals

English nouns are inflected for grammatical number, meaning that if they are of the countable type, they generally have different forms for singular and plural. This article discusses the variety of ways in which plural nouns are formed from the corresponding singular forms, as well as various issues concerning the usage of singulars and plurals in English. For plurals of pronouns, see personal pronouns

Quantifier

Quantifiers indicate quantity. Some examples of quantifiers include: all, some, many, few, and no. Quantifiers are also dependent of a noun. It is important to acknowledge that quantifiers only indicate a vague quantity of objects, not a specific number, such as twelve, dozen, first, single, or once, which would be considered numerals.

B2 | Upper Intermediate

B2, or Upper Intermediate, is the fourth level on the CEFR scale. It marks the point where you move from "getting by" to genuinely comfortable communication — handling complex topics, expressing nuanced opinions, and understanding most of what you read or hear in real-world contexts.

What a B2 user can do

At this level, you're expected to:

  • Understand complex texts on both concrete and abstract topics, including technical discussions in your own field.
  • Follow extended speech and lectures, even when the structure isn't entirely clear, as long as the topic is reasonably familiar.
  • Interact fluently and spontaneously enough that conversations with native speakers flow naturally — without strain on either side.
  • Produce clear, detailed text on a wide range of subjects, using connectors and cohesive devices to build well-structured arguments.
  • Explain and defend a viewpoint on a topical issue, weighing the advantages and disadvantages of different options.
  • Recognize implicit meaning — reading between the lines in demanding, longer texts.

What B2 grammar looks like in practice

B2 is where grammar stops being about isolated rules and starts being about flexibility and precision. You're expected to control structures like:

  • Advanced conditionals and mixed conditionals — moving beyond simple if-clauses to express hypothetical and counterfactual meaning.
  • Passive voice in varied tenses and contexts, not just present and past simple.
  • Reported speech with correct sequence of tenses, including backshifting and reporting verbs.
  • Participle clauses and the distinction between participles and gerunds.
  • Comparative and superlative structures beyond basic -er/-est, including double comparatives and qualifying expressions.

Errors still happen at B2, but they rarely cause misunderstanding. The goal is controlled, flexible use of language across social, academic, and professional settings.

How B2 fits in the CEFR progression

B2 builds directly on the foundations of B1 (Intermediate) and prepares you for C1 (Advanced). Many university entrance exams, professional certifications, and immigration requirements target B2 as the minimum standard.

Self-check: If you can read a newspaper editorial, follow most of a TED talk without subtitles, and write a clear essay arguing a position — you're likely operating at B2.
