Advanced Conditionals and Wish
This challenge focuses on advanced uses of conditionals and the structure "wish" in English grammar. Conditionals are sentences that describe possible situations and their outcomes, often using "if." Beyond basic forms, advanced conditionals include mixed conditionals (combining different time frames) and nuanced usage of "if only" and "wish" for expressing regrets, hypothetical desires, or unreal situations.
For example, a mixed conditional might be: "If I had studied medicine, I would be a doctor now" (past condition, present result). The structure "wish" is used to express unreal or regretted situations, such as "I wish I had known about the meeting" (regret about the past) or "I wish it would stop raining" (desire for a change in the present/future). Mastering these forms is essential for expressing complex ideas and emotions in English.
Understanding the subtle differences between various conditional forms and wish statements will help you sound more fluent and precise. This quiz will test your ability to identify, correct, and construct sentences using advanced conditionals and "wish" appropriately.

Correct Answers
Select the grammatically correct sentence expressing an unreal past conditional.
The correct answer is If you had told me earlier, I could have helped you.
In third (unreal past) conditionals, the correct structure is "if + past perfect," followed by "would/could/might have + past participle."
Choose the correct word to complete the sentence expressing a present unreal wish.
I wish I ___ more fluent in French.
The correct answer is were.
After "wish" for present unreal situations, we use the past simple or "were" for all persons.
Select the correct sentence that uses "should" in an inverted first conditional.
The correct answer is Should you see Emma, tell her I said hello.
We can invert the first conditional by starting with "should" + subject + base verb instead of "if."
Choose the best option to complete the sentence with a mixed conditional.
If he ___ harder at university, he would have a better job now.
The correct answer is had studied.
In mixed conditionals expressing a past action with a present result, use "if + had + past participle" in the if-clause and "would + base verb" in the result clause.
The correct answers are If she had known about the meeting, she would have attended. and If I had studied harder, I might have passed the exam.
Third (past unreal) conditionals use "if" + past perfect, and "would have/could have/might have" + past participle in the result clause. "If you would have called..." is incorrect; use "If you had called...".
The correct answers are I wish I were taller. and She wishes she knew the answer.
To express present unreal wishes, use "wish" + past simple (or "were" for all persons), NOT "will" or present tense.
The correct answers are If I had listened to your advice, I wouldn't be in trouble now. and If she had married him, she would be happier today.
Mixed conditionals often use "if" + past perfect (for the past situation) + "would" + base verb (for the present result).
The correct answers are If you should need any help, just let me know. and If I were you, I would reconsider the offer.
"Should" can be used for polite or less probable first conditionals. In unreal present conditionals, "would" goes in the main clause, not in the "if" clause. "Wish" for present states uses "wish" + past simple, not "would have".
The correct answers are had known and would have come.
In third (past unreal) conditionals, use "if + past perfect" and "would have + past participle" to express regrets or hypothetical situations in the past.
The correct answers are were and had started.
For wishes about the present, use "were" (subjunctive) after "I wish." For wishes about the past, use "had + past participle."
The correct answers are should see and have called.
"If you should see..." is a formal way to express a possible future event (first conditional with inversion). "Have called" matches the present perfect tense for a recent action.
The correct answers are were to win and might travel.
The structure "If I were to win..." expresses a hypothetical future situation. "Might travel" is an appropriate modal verb for a less certain, hypothetical result.
Conditional sentence
- ✅ If you heat ice, it melts. — zero conditional (always true)
- ✅ If it rains, I*'ll** take an umbrella.* — first conditional (real future)
- ✅ If I had wings, I would fly. — second conditional (unreal present)
- ✅ If I had left earlier, I would have caught the train. — third conditional (unreal past)
Conditional sentences pair an if-clause with a consequence. Five patterns (zero through mixed) each combine specific tenses to express different levels of reality and time.
Pattern: the tense in the if-clause is always one step "back" from what you'd expect — past for present hypotheticals, past perfect for past hypotheticals.
Modal verb
- ✅ She can swim. — ❌ She can to swim. (modal + bare infinitive, no to)
- ✅ You must leave now. — strong obligation
- ✅ It might rain. — possibility (~50%)
- ✅ He should apologise. — advice/recommendation
Modal verbs (can, could, may, might, must, shall, should, will, would) are auxiliaries expressing ability, permission, possibility, obligation, or speculation. Always + bare infinitive. Never inflected (she can, not she cans).
Rule: modals never take to after them, never add -s for third person, and can't combine directly (must can ❌ — use must be able to).
Subjunctive mood
- ✅ If I were you… — past subjunctive (not was)
- ✅ I suggest that he go. — present subjunctive (not goes)
- ✅ It's important that she be present. — present subjunctive
- ❌ If I was you… — common in speech, avoided in formal writing
The subjunctive uses bare-infinitive forms (go, be) after verbs of demand/suggestion, and were (not was) in unreal/hypothetical conditions. Two contexts: that-clauses (I insist that he leave) and if-clauses (If she were here).
Rule: after suggest/recommend/demand/insist that… → use base form. In if + unreal condition → use were for all persons.
Verb
- walk → walk / walks / walked / walked / walking (5 forms, regular)
- go → go / goes / went / gone / going (5 forms, irregular)
- be → am/is/are/was/were/be/being/been (8 forms)
- can → can / could (modal: only 2 forms, no -s, no -ing)
A verb is the one word class every English sentence requires. Carries tense (when), aspect (duration), mood (attitude), and voice (active/passive). Regular verbs add -ed; ~200 irregular verbs have unpredictable past forms.
Key insight: fix your verbs and most grammar problems disappear. Wrong tense, wrong agreement, wrong form — verb errors account for the majority of grammatical mistakes.
Verb tense
| Simple | Progressive | Perfect | Perfect Progressive | |
|---|---|---|---|---|
| Past | worked | was working | had worked | had been working |
| Present | work(s) | am working | have worked | have been working |
| Future | will work | will be working | will have worked | will have been working |
Verb tense = time (past/present/future) × aspect (simple/progressive/perfect) = 12 forms. Each slot has a specific job — not just "when" but "how the action relates to its time frame."
Key insight: most learners don't need all 12 at once. Simple covers 80% of communication. Add perfect and progressive as needed.
B2 | Upper Intermediate
- ✅ If I had studied harder, I would have passed. — third conditional
- ✅ The report is being reviewed by the committee. — passive progressive
- ✅ Having finished the exam, she left. — participle clause
- ✅ He denied having taken the money. — complex verb pattern
These are B2 patterns — the CEFR upper-intermediate level. At B2 you handle mixed conditionals, all passive forms, participle clauses, and can argue a point clearly. This is the level most universities and employers require.
Marker: if you can write a structured essay and debate an abstract topic, you're B2.
Hard
- Had she not intervened, the situation would have escalated. — inverted conditional
- All distractors are grammatically plausible in other contexts
- Multiple rules interact (e.g., tense + aspect + modality)
- Context determines the answer — no single "rule" is enough
Hard marks upper-intermediate to advanced challenges: B2+, interacting rules, edge cases, plausible distractors, and contexts where pattern-matching fails.
Use "Hard" when Easy/Medium feel trivial and you want to test whether you actually understand a rule versus just recognising surface patterns.
