5.3 Conditionals and Wishes
Key Takeaways
- Zero conditional: if/when + present, present — general truths. First: if + present, will/modal + base — real future. Second: if + past, would + base — unreal present/future. Third: if + past perfect, would have + past participle — unreal past.
- Mixed conditionals combine times (e.g., if + past perfect, would + base for past cause → present result).
- Unless ≈ if not; provided that / as long as mark restrictive conditions; even if marks concessive conditions.
- Wish / if only + past simple (present regret/desire); + past perfect (past regret); + would (annoyance / desire for change in others’ behavior).
- As if / as though often take past forms for unreality (*as if she were* / *as if she had known*); iTEP may also accept informal was in some stems—prefer formal were for unreal present.
5.3 Conditionals and Wishes
Quick Answer: iTEP Grammar frequently tests conditional time frames and wish / if only patterns. Match if-clause tense to result-clause form: zero (facts), first (real future), second (unreal present), third (unreal past), and mixed. Related frames: unless, provided that, as if / as though.
The five frames (memorize the skeletons)
| Type | If-clause | Result clause | Use |
|---|---|---|---|
| Zero | if/when + present | present | Laws, habits, scientific truths |
| First | if + present | will / can / may / should + base | Real/possible future |
| Second | if + past simple | would / could / might + base | Unreal/hypothetical present or future |
| Third | if + past perfect | would have / could have / might have + past participle | Unreal past (didn’t happen) |
| Mixed | often past perfect or past | mismatched time in result | Past cause → present result (or reverse patterns) |
Examples
- Zero: If water reaches 100°C, it boils.
- First: If the registrar opens early, we will submit today.
- Second: If I were eligible, I would apply this cycle.
- Third: If she had registered on time, she would have taken the exam in May.
- Mixed (past → present): If he had studied statistics last year, he would understand this model now.
- Mixed (present → past): If she were more careful, she would not have lost the file yesterday. (less common but possible)
Form details that create traps
Comma rule (awareness): When the if-clause comes first, a comma usually follows it. When the result comes first, no comma: We will submit today if the registrar opens early. iTEP rarely scores punctuation alone, but stems may use either order.
Were for unreal present: Formal academic English prefers If I were / If she were for hypothetical present (subjunctive). If I was appears in informal speech; on a careful iTEP academic stem, were is often the safer option when options contrast was/were for unreal meaning.
No will in the if-clause (standard first conditional): If it will rain, we cancel is usually wrong → If it rains, we will cancel. Exception-like cases (if you will wait = willingness) are rare and stylistically marked.
Would in the if-clause: Avoid for ordinary second/third frames (If you would study is not the default second conditional). Would belongs in the result clause unless the stem is a polite request formula.
Unless, provided that, as long as, even if, in case
| Linker | Meaning | Rough paraphrase |
|---|---|---|
| unless | if not | Unless you register, you cannot sit ≈ If you do not register… |
| provided (that) / providing (that) | only if | condition that must be met |
| as long as | only if / while condition holds | similar to provided that |
| even if | concessive | condition doesn’t block the result |
| in case | precaution | Take a charger in case the battery dies (not pure if) |
iTEP trap: Double negative with unless. Unless you don’t register is usually wrong when the writer meant simple unless you register. Prefer one clear negative meaning.
iTEP trap: even if vs if. Even if it rains, the tour continues means rain does not stop the tour. Replacing even if with if changes logic.
Wishes and if only
| Target meaning | Structure | Example |
|---|---|---|
| Present desire / regret about now | wish / if only + past simple | I wish I knew the answer. |
| Past regret | wish / if only + past perfect | I wish I had studied more. |
| Desire for change / annoyance at others | wish + would + base | I wish the printer would stop jamming. |
| Future desire (careful) | often hope + present/future, not wish + will | I hope you pass (not I wish you will pass) |
Parallel with second/third conditionals: Wish present uses past forms (like second conditional distance). Wish past uses past perfect (like third).
If only intensifies the same patterns: If only the results were available now. / If only I had saved the draft.
As if / as though
These introduce comparisons that may be unreal:
- Unreal present: She acts as if she were the director.
- Unreal past: He spoke as though he had written the policy himself.
- Real-seeming present (less “counterfactual”): It looks as if it is going to snow.
iTEP fill-ins may force were vs was or had known vs knew after as if. Prefer the more distant (past/past perfect) form when the comparison is clearly counterfactual.
Common wrong patterns (error-ID gold)
| Wrong | Right |
|---|---|
| If I will see her, I tell her. | If I see her, I will tell her. |
| If I would have known… | If I had known… |
| If I knew, I will help. (unreal present) | If I knew, I would help. |
| I wish I know French. | I wish I knew French. |
| I wish I studied harder last year. (past regret) | I wish I had studied harder last year. |
| Unless you will not go… (messy) | Unless you go… / If you do not go… |
Mixed conditionals on academic stems
Academic sentences often encode past research choice → present knowledge gap:
If the team had collected baseline data in 2024, the model would be more reliable today.
Or present permanent state → past consequence:
If she were a registered student, she would have received the fee waiver last month.
When options mix had + past participle in one clause with would + bare infinitive in the other, check whether the time of cause and time of result match the intended logic—not whether both clauses “look the same.”
Exam strategy under time pressure
- Underline the time words: now, today, yesterday, last year, by then, in the future.
- Decide: real vs unreal; present/future vs past.
- Apply the skeleton table; reject will in ordinary if-clauses and would have without a past-perfect if (unless mixed intentionally).
- For wish, ask: regret about now (past simple) or then (past perfect) or someone’s behavior (would)?
- For unless, rephrase as if not and see if the result still makes sense.
Conditionals and wishes are pattern systems. Once the five skeletons and the three wish shapes are automatic, these items become some of the fastest advanced points on the Grammar section—freeing seconds for multi-clause relative and noun-clause stems.
