Turn this statement into a question.

"She read a book last week."

Select the correct option.

The question is formed by using the auxiliary verb "did" before the subject "she," followed by the base form of the verb "read."

Verb

Verb vs noun vs adjective: nouns name things. Adjectives describe. Verbs express what happens or what IS. The test: can it take tense (walked, will walk)? Can it take -ing? Can it follow to as an infinitive (to walk)? Yes to any → verb. English often converts freely between classes (run = noun or verb), so context decides.

A verb = action/state/occurrence word. 5 forms (base, -s, past, past participle, -ing). Carries tense, aspect, mood, voice. The one required element in every sentence.

Diagnostic: does it change for tense (walk → walked)? Can you put to before it (to walk)? Does it take -ing (walking)? → verb.

Past tense

Simple past vs past perfect: simple past puts events on the main timeline (I arrived. She left.). Past perfect marks an event as earlier than another past event (She had left before I arrived). If all events are in sequence, simple past is enough. Only use past perfect when you need to show "earlier than the main story."

The past tense has four forms encoding different temporal relationships: simple past, past progressive, past perfect, past perfect progressive.

Diagnostic: are events in sequence? → simple past is fine. Need to show one event happened before another past event? → past perfect for the earlier one.

Irregular verb

Irregular vs regular verbs: regular verbs add -ed for both past tense and past participle (walked, played, watched). Irregular verbs change form unpredictably (went, eaten, thought). The catch: the 200 most frequent English verbs are mostly irregular — so you can't avoid them.

Irregular verbs break the -ed pattern: go/went/gone, be/was/been, have/had/had. ~200 common ones, heavily concentrated in everyday speech.

Diagnostic: does adding -ed sound wrong (goed ❌)? → it's irregular. Look up the correct past and participle forms — there's no shortcut past memorisation.

Questions

Direct vs indirect questions: direct questions invert and end with ? (Where does she live?). Indirect questions DON'T invert and end with a period (I wonder where she lives.). Mixing these up — I wonder where does she live? ❌ — is one of the most common structural errors.

Questions in English use inversion/do-support. Types: yes/no, wh-, negative, tag. Direct questions invert; indirect don't.

Diagnostic: is your question embedded inside a statement (I wonder, Do you know, Can you tell me)? → DON'T invert. Is it a standalone question? → invert.

A1 | Elementary | Beginners

A1 vs A2: A1 covers isolated survival phrases (Where is…?, I am…, How much?). A2 handles connected sentences about familiar routines and simple past events. If you can manage short fixed phrases but not string together original sentences about your day, you're still A1.

A1 is the entry level of the CEFR: greetings, introductions, numbers, basic present tense, and core function words.

Diagnostic: can you describe yesterday using past tense? No → A1. Yes → you're moving into A2.

Easy

Easy vs Medium vs Hard: Easy = one rule, obvious answer, A1A2. Medium = one rule but realistic distractors, A2B1. Hard = interacting rules, edge cases, B2+. Start Easy to check you have the basics before moving up.

The Easy tag filters for single-rule, short-sentence, common-vocabulary challenges designed for beginners or for anyone wanting a confidence check on fundamentals.

Diagnostic: if you get Easy questions wrong, stay here — your foundations need work. If they feel trivial, move to Medium.
