Choose the right phrase to complete the hungry roommate's midnight suggestion.

Let's sneak down to the kitchen and steal the last slice of pizza, _____?

The correct answer is shall we.

When we make a suggestion starting with "Let's" (which is short for "Let us"), the standard question tag to use is always "shall we?".

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?

Indicative

Indicative mood, in English, refers to finite verb forms that are not marked as subjunctive and are not imperatives or conditionals. They are the verbs typically found in the main clauses of declarative sentences and questions formed from them, as well as in most dependent clauses (except for those that use the subjunctive). The information that a form is indicative is often omitted when referring to it: the simple present indicative is usually referred to as just the simple present, etc. (unless some contrast of moods, such as between indicative and subjunctive, is pertinent to the topic).

Subjunctive

Certain types of clause, mostly dependent clauses, use a verb form identified with the subjunctive mood. The present subjunctive takes a form identical to the bare infinitive, as in It is necessary that he be restrained. There is also a past subjunctive, distinct from the indicative only in the possible use of were in place of was in certain situations: If I were you, ...

Imperative

An independent clause in the imperative mood uses the base form of the verb, usually with no subject (although the subject you can be added for emphasis).

Negation uses do-support (i.e. do not or don't). For example:

  • Now eat your dinner.
  • You go and stand over there!
  • Don't ever say that word again.

Sentences of this type are used to give an instruction or order. When they are used to make requests, the word please (or other linguistic device) is often added for politeness:

  • Please pass the salt.

First person imperatives (cohortatives) can be formed with let us (usually contracted to let's), as in "Let's go". Third person imperatives (jussives) are sometimes formed similarly, with let, as in "Let him be released".

Conditional

The status of the conditional mood in English is similar to that of the future tense: it may be considered to exist provided the category of mood is not required to be marked morphologically). The English conditional is expressed periphrastically with verb forms governed by the auxiliary verb would. The modal verb could is also sometimes used as a conditional (of can).

In certain uses, the conditional construction with would/should may also be described as "future-in-the-past".

B1 | Intermediate

B1 is the intermediate level of the Common European Framework of Reference for Languages (CEFR). It marks the point where you move beyond survival English and start expressing yourself with real independence — describing experiences, explaining opinions, and handling everyday situations without a script.

What a B1 user can do

At this level, you're expected to:

  • Understand the main points of clear, standard speech and writing on familiar topics — work, school, travel, hobbies.
  • Handle most travel situations in English-speaking environments.
  • Produce simple connected text on topics you know or care about.
  • Describe experiences, events, hopes, and plans, and give brief reasons and explanations for your opinions.
  • Communicate in routine tasks that require a straightforward exchange of information.

What B1 grammar looks like

B1 is where grammar starts to get more layered. You're not just forming basic sentences anymore — you're combining ideas, using different tenses with more precision, and starting to handle structures like the passive voice, modal verbs for necessity and possibility, and gerunds vs. infinitives. You're also expected to build complex sentences with linking words and dependent clauses.

Typical B1 grammar areas include:

  • Future tenses — distinguishing will, going to, and the present continuous for future plans
  • Passive voiceThe report was written yesterday.
  • Modal verbsYou should apply early. / She might be late.
  • Used toI used to live in Berlin.
  • Verb patterns — knowing whether a verb takes a gerund, an infinitive, or both (I enjoy reading vs. I decided to leave)

What B1 doesn't mean

B1 speakers still hesitate, make grammatical errors, and sometimes struggle with less familiar topics. That's normal. The key difference from A2 is that you can keep a conversation going and get your point across even when things aren't perfect. The step up to B2 involves handling more abstract topics, understanding nuance, and producing more complex, accurate language.

Self-check: Can you tell a friend about a recent trip — what happened, what you liked, and what you'd do differently — without switching to your native language? If yes, you're likely operating at B1 or above.
