You are venting to your best friend about your slightly annoying (but lovable) roommate.
Select ALL the complaints that apply and are grammatically correct.

The correct answers are He usually forgets to take out the recycling on Tuesdays. and He is constantly singing loud opera in the shower at 2 AM!

Explanation:

  • usually forgets: Present Simple is used for regular habits and routines.
  • is constantly singing: Present Continuous, when paired with words like "constantly" or "always," perfectly expresses an annoying, repeated habit.
  • is completely ignoring... every single week is incorrect. Since it happens "every single week" (a routine), it should be in the Present Simple ("completely ignores").
  • plays... right now is incorrect. Actions happening exactly at the moment of speaking need the Present Continuous ("is playing").

Present tense

  • I work here. — simple present (habit/permanent)
  • I am working now. — present progressive (happening right now)
  • I have lived here for 10 years. — present perfect (started past, still true)
  • I have been waiting for an hour. — present perfect progressive (duration up to now)

Four present tense forms: simple (habits/facts), progressive (now/temporary), perfect (past → present relevance), perfect progressive (ongoing duration). Each encodes a different relationship between the action and the present moment.

Trap: "I am living here for 10 years" ❌ — started in the past + still true = present PERFECT (have lived/have been living), not progressive.

Simple tense

  • I go to work every day. — present simple (habit)
  • She went home yesterday. — past simple (completed action)
  • I will call you later. — future simple (promise/decision)
  • Water boils at 100°C. — present simple (general truth)

The simple aspect is the default, unmarked verb form. Present simple = habits, facts, schedules. Past simple = completed actions. Future simple = predictions, promises, decisions. No auxiliary needed (except will for future and do for questions/negatives).

Rule: if the action is a fact, habit, completed event, or scheduled future — and you don't need to emphasise it being in-progress or connected to now → simple tense.

Progressive tense

  • I am working in London. — temporary, happening now
  • I work in London. — permanent/habitual (simple)
  • I am knowing the answer. — stative verb, can't be progressive
  • She was reading when I arrived. — past progressive (in progress at that moment)

The progressive = be + -ing. Marks actions as ongoing, temporary, or in-progress at a reference time. NOT used with stative verbs (know, believe, own, want, like) unless meaning shifts.

Rule: is the action temporary/in-progress right now? → progressive. Is it a permanent fact, habit, or schedule? → simple. Is it a stative verb? → almost never progressive.

Habits and Routines

  • I always get up at 7. — ❌ I get up always at 7. (adverb before main verb)
  • She usually walks to work. — present simple for current habit
  • I used to smoke. — past habit (no longer true)
  • He would always bring flowers.would for repeated past actions

Habits and routines use present simple + frequency adverbs for current habits, and used to / would for past habits. Adverb placement: before the main verb, after be.

Rule: frequency adverbs (always, usually, often, sometimes, never) go BEFORE the main verb but AFTER be: She always eats breakfast vs She is always hungry.

B1 | Intermediate

  • If I had more time, I would travel more. — second conditional
  • The bridge was built in 1920. — passive voice
  • She said she was tired. — reported speech with backshift
  • Although it rained, we enjoyed the trip. — complex sentence with concession

These are B1 patterns — the CEFR intermediate level. At B1 you link ideas, use passive voice, handle reported speech, and manage second conditional — enough for travel, work basics, and everyday independence.

Marker: if you can explain why something happened and follow a news story, you're B1.

Easy

  • She is a teacher. — one verb form, one rule
  • I have two cats. — basic possession, short sentence
  • He doesn't like coffee. — simple negation with do-support
  • Only one answer is clearly correct; distractors are obviously wrong.
