Help the frustrated detective complete his case notes by dragging the correct phrases into the report.

"I asked the witness exactly how large the ship was."

"He completely refused to tell me where the aliens went."

"I asked the witness exactly how large the ship was."

In an indirect question, the subject ("the ship") must come before the verb ("was"). "How large was the ship?" is only correct as a direct, standalone question.

"He completely refused to tell me where the aliens went."

Indirect questions do not use "do/does/did" for past or present simple tense. We drop the "did" and put the main verb straight into the past tense ("went").

Questions

Like many other Western European languages, English historically allowed questions to be formed by inverting the positions of verb and subject. Modern English permits this only in the case of a small class of verbs ("special verbs"), consisting of auxiliaries as well as forms of the copula be. To form a question from a sentence which does not have such an auxiliary or copula present, the auxiliary verb do (does, did) needs to be inserted, along with inversion of the word order, to form a question. For example:

  • She can dance. → Can she dance? (inversion of subject she and auxiliary can)
  • I am sitting here. → Am I sitting here? (inversion of subject I and copula am)
  • The milk goes in the fridge. → Does the milk go in the fridge? (no special verb present; do-support required)

The above concerns yes-no questions, but inversion also takes place in the same way after other questions, formed with interrogative words such as where, what, how, etc. An exception applies when the interrogative word is the subject or part of the subject, in which case there is no inversion. For example:

  • I go. → Where do I go? (wh-question formed using inversion, with do-support required in this case)
  • He goes. → Who goes? (no inversion, because the question word who is the subject)

Note that inversion does not apply in indirect questions: I wonder where he is (not *... where is he). Indirect yes-no questions can be expressed using if or whether as the interrogative word: *Ask them whether/if they saw him*.

Negative questions are formed similarly; however if the verb undergoing inversion has a contraction with not, then it is possible to invert the subject with this contraction as a whole. For example:

  • John is going. (affirmative)
  • John is not going. / John isn't going. (negative, with and without contraction)
  • Isn't John going? / Is John not going? (negative question, with and without contraction respectively)

Tag questions are formed with a special verb and pronoun subject: isn't it?; were there?; am I not?

Word Order

The primary word orders that are of interest are

  • the constituent order of a clause, namely the relative order of subject, object, and verb;
  • the order of modifiers (adjectives, numerals, demonstratives, possessives, and adjuncts) in a noun phrase;
  • the order of adverbials.

Constituent word order is defined in terms of a finite verb (V) in combination with two arguments, namely the subject (S), and object (O).

There is a difference between grammatical word order and natural word order. In many languages, topicalization and questions can change the grammatical word order.

Examples

A: [Kate loves who/Who does Kate love?] (SVO/OSV)
B: [She loves Mark/Mark is who she loves.] (SVO/OSV)

In the (A) sentences, the first one is used when putting emphasis on who Kate loves, and the second is used with more of a quizzical tone. English uses stress and tone to emphasize different aspects of the sentences, which can also change the word order, as shown above.

In the (B) sentences, the first one is more likely to be used by a native English speaker. The second sentence is grammatical as well, but less likely to be said in natural speech. This is because English uses the SVO structure in regular sentences, but is able to answer questions using the same structure that was used in the sentence.

In English, you can change the word order depending on what you want to emphasize.

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.
