Other Expressions in Conditionals Exercises
Most English learners, when they learn conditionals, focus on if. However, at B2 level it is important to widen your vocabulary with alternative expressions such as unless, even if, provided (that), as long as, in case, on condition that. These structures will help you to sound more natural, precise and flexible in both speaking and writing.
Unless (Meaning: if not)
Unless is often used in real situations, replacing if…not.
Structure:
Unless + present simple, main clause
Examples:
- You won’t pass the exam unless you study harder.
(= if you do not study harder) - We’ll be late unless we leave now.
Tip: Do not use not in the same clause as unless.
Unless you don’t hurry → Unless you hurry
Even If (Meaning: no matter whether)
Even stresses that the result will not change, whatever the condition.
Structure:
Even if + condition, result
Examples:
- I will go out even if it rains.
- She won’t change her mind even if you ask her.
Use when the condition is not a determinant of the outcome.
Provided (That) / Providing (That)
(Meaning: only if)
These are more formal options for if and are often used in rules, agreements or conditions.
Structure:
Main clause + provided (that) + condition
Examples:
- You can borrow my car provided that you drive carefully.
- We’ll sign the contract providing that all terms are clear.
Common in formal writing and business English.
As Long As / So Long As
(Meaning: if and only if / on the condition that)
Used to stress a condition that must be fulfilled.
Structure:
Main clause + as long as + condition
Examples:
- You can stay here as long as you keep quiet.
- I’ll support you so long as you’re honest.
Difference from given:
- As long as is often an indication of duration or continuing condition.
In Case (Meaning: because something might happen)
In case is for precautions, not conditions.
Structure:
Main clause + in case + present tense
Examples:
- Take an umbrella in case it rains.
- I’ll save some money in case I need it later.
Important:
- Do NOT use will after in case
in case it will rain → in case it rains
On Condition That (Formal)
More formal way to say strict conditions.
Structure:
Main clause + on condition that + clause
Examples:
- They agreed to help on condition that we paid in advance.
- He will join the team on condition that he gets a contract.
A Quick Comparison
| Expression | Meaning | Use Case |
|---|---|---|
| unless | if not | General negative condition |

The key at B2 level is variety. So don’t always use if, use these alternatives instead and make your English more advanced and natural and improve your fluency.
Practice regularly with exercises and focus on meaning differences, not just structure.
