Help the exhausted college student refine the dramatic conclusion of their research paper on caffeine by choosing the correct adverbs.
While it is _________________________ impossible to survive finals week without coffee, students are becoming _________________________ dependent on espresso shots. Consequently, university health officials are _________________________ concerned about this rising trend.

While it is virtually impossible to survive finals week without coffee, students are becoming heavily dependent on espresso shots. Consequently, university health officials are deeply concerned about this rising trend.

Virtually impossible means almost entirely impossible.

Heavily dependent is a strong collocation used to describe relying on something to a great degree.

Deeply concerned is the standard academic and formal collocation for expressing serious worry.

Adverb

An adverb is a word that modifies a verb, adjective, determiner, clause, preposition, or sentence. Adverbs typically express manner, place, time, frequency, degree, level of certainty, etc., answering questions such as how?, in what way?, when?, where?, and to what extent?. This function is called the adverbial function, and may be realized by single words (adverbs) or by multi-word expressions (adverbial phrases and adverbial clauses).

Adverbs are traditionally regarded as one of the parts of speech. However, modern linguists note that the term "adverb" has come to be used as a kind of "catch-all" category, used to classify words with various different types of syntactic behavior, not necessarily having much in common except that they do not fit into any of the other available categories (noun, adjective, preposition, etc.)

Adjective

An adjective is a word that describes or modifies a noun or pronoun, giving more information about its qualities, state, or identity. Adjectives are one of the core parts of speech in English, and you use them constantly — to describe people, objects, feelings, and ideas.

What adjectives do

Adjectives typically answer questions like What kind?, Which one?, or How many? They can appear in two main positions:

  • Before a noun (called attributive position): a tall building, fresh coffee, three students
  • After a linking verb (called predicative position): The soup is hot, She seems tired

Some adjectives work in only one position. For example, main is almost always attributive (the main reason), while asleep is almost always predicative (The baby is asleep).

Examples

  • ✅ She wore a red dress. (red modifies dress)
  • ✅ The exam was difficult. (difficult follows the linking verb was)
  • ❌ She wore a redly dress. (Adverbs like redly don't modify nouns.)
  • ✅ He gave me useful advice. (useful modifies the uncountable noun advice)

Adjective order

When you stack multiple adjectives before a noun, English follows a conventional order: opinion → size → age → shape → colour → origin → material → purpose. For example, a lovely small old round brown French wooden serving table — though in real life you'd rarely pile up that many.

Self-check: If your sentence sounds awkward with two adjectives before a noun, try swapping their order. The version that "sounds right" usually follows the standard sequence.

Adjectives vs. determiners

Words like the, this, my, and some were historically grouped with adjectives, but modern grammar classifies them as determiners. Unlike true adjectives, determiners don't have comparative forms (bigger works, but *more the doesn't) and occupy a fixed slot before any adjectives.

Comparatives and superlatives

Most adjectives have comparative and superlative forms used to compare things:

  • tall → taller → tallest
  • expensive → more expensive → most expensive

To practice these, try Comparatives and Superlatives. You can also build a foundation with Basics. Adjectives and Adverbs. and Basics. Word Order..

Collocations

Collocations are combinations of words that are frequently used together in a particular order, forming a natural-sounding expression. These word pairs or groups often sound more natural to native speakers than other possible combinations of the same words. Understanding collocations is important for language learners because they help you sound more fluent and natural when speaking or writing.

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.
