The correct answers are I wish I didn't have to work tomorrow. and If only we lived in a giant mansion.
We use the past simple ("didn't have to", "lived") to talk about imaginary present or future situations.
"Are" is present tense (it should be "were"). Also, we generally cannot use wish + would with "I" or "we" to talk about our own actions—we use "could" or the past simple instead!
Verb mood
If grammar references confuse you with terms like "subjunctive" or "conditional" — and you've never quite understood why English needs them — you've hit the verb-mood layer. Each mood marks a different attitude: fact vs command vs hypothetical vs polite recommendation. Once that map is clear, structures like if I were you or I suggest he go stop looking like exceptions and start looking like a system.
Verb mood signals the speaker's attitude toward the action. The four English moods: indicative (facts), imperative (commands), subjunctive (hypotheticals, formal recommendations), and conditional (would/could constructions).
Subjunctive mood
If you've heard if I were you and wondered why it's not if I was you — you've met the past subjunctive. English barely marks the subjunctive anymore, but in formal writing and a few stock phrases, getting it right (or wrong) is one of the clearest signals of a careful writer. I demand that he be present. / If I were richer. — both subjunctive, both reading as wrong if you swap them out.
The subjunctive mood marks hypothetical or counterfactual contexts. Two main forms: present subjunctive in that-clauses after verbs of recommendation (I suggest that he go) and past subjunctive were in unreal conditionals (If I were you). Mostly invisible in modern English, but unmistakable when present.
Conditional sentence
Want to say I would have caught the train if I'd left earlier without freezing on the verb forms? That's a third conditional, and it's one of five patterns English uses to talk about possibilities, regrets, and hypotheticals. Get the system right and you stop sounding stuck in the present tense.
A conditional sentence pairs a condition clause (usually with if) with a consequence clause: If it rains, we stay in. The five named patterns — zero, first, second, third, and mixed — each match a specific time frame and likelihood, with their own tense rules.
Past tense
If you've ever told a story in English and felt the timeline get tangled — I came home, the dog ate, the cat slept — you've hit the limits of using simple past for everything. The past tense system has four forms specifically because real stories have layered timing: things that happened before other things, actions caught in progress, sequences of completed events.
The past tense has four English forms: simple past (I walked), past progressive (I was walking), past perfect (I had walked — earlier than another past event), past perfect progressive (I had been walking — ongoing up to a past point). Plus irregular verbs for the simple-past form.
B1 | Intermediate
If you can hold a conversation about your weekend, explain why you're late, and follow a short news story without panicking — but still feel lost in fast or technical English — you're probably operating at B1. Knowing this matters: study material at the wrong level either bores you or burns you out, and B1 is the typical target for travel, casual work, and most everyday social English.
B1 is the intermediate level in the CEFR framework, where you handle everyday English independently and start combining ideas with complex sentences, passive voice, and modal verbs.
Difficulty: Medium
If easy questions feel too obvious but hard questions leave you guessing, you're probably ready for Medium — the level where most real learning happens. It pushes just enough to expose the rules you don't quite have yet, without burying you in edge cases. This is where steady fluency is built, one well-aimed challenge at a time.
The Medium difficulty tag marks middle-range challenges — typically A2 to B1. One rule per question, realistic distractors, and contexts that require active thought rather than instant recognition.
