If you now, you will catch the train.

Correct answer: leave

First conditional if-clause: always present simple. "Will catch" in the result tells us this is first conditional, so the if-clause needs "leave", not "will leave".

If she her homework, she won't go out.

Correct answer: doesn't finish

First conditional if-clause: present simple negative — "doesn't finish". Using "won't finish" in the if-clause is a very common error; only the result clause uses "will/won't".

He will feel better if he this medicine.

Correct answer: takes

First conditional if-clause: present simple. He/she/it → add -s: "takes". "Will feel" in the result clause confirms first conditional — a real future possibility.

We the party outside if the weather is good.

Correct answer: will have

First conditional result clause: "will + base verb". The if-clause "is good" (present simple) confirms this is first conditional.

If they on time, we can start the meeting.

Correct answer: arrive

First conditional if-clause: present simple — "arrive". The result uses "can" (not "will") here, which is also valid in first conditional to express possibility.

I you if I need any help.

Correct answer: will call

First conditional result clause: "will + base verb". The if-clause "if I need" (present simple) confirms first conditional.

If she the driving test, she will buy a car.

Correct answer: passes

First conditional if-clause: present simple. She/he/it + pass → "passes" (add -es after -ss). Never use "will pass" in the if-clause.

If the manager the plan, we will start next week.

Correct answer: approves

First conditional if-clause: present simple — "approves". Using "will approve" here is incorrect; "will" only goes in the result clause.

If I more time, I would learn another language.

Correct answer: had

Second conditional if-clause: past simple — "had". The result "would learn" signals second conditional for a hypothetical present situation. "Have" (present) would create first conditional.

She would travel the world if she the lottery.

Correct answer: won

Second conditional if-clause: past simple — "won". "Would travel" in the result clause confirms this is second conditional for an unlikely/imaginary situation.

If he taller, he could play basketball professionally.

Correct answer: were

Second conditional if-clause: past simple of be. "Were" is the traditional/formal form used for all persons (especially in writing), though "was" is widely accepted in informal speech.

I a bigger flat if I earned more money.

Correct answer: would buy

Second conditional result clause: "would + base verb". "Earned" (past simple) in the if-clause confirms second conditional — an imaginary present situation.

If they near the sea, they would swim every day.

Correct answer: lived

Second conditional if-clause: past simple — "lived". "Would swim" in the result clause confirms this describes an imaginary situation (they do not actually live near the sea).

If I were you, I for a new job.

Correct answer: would look

"If I were you" is a fixed second conditional expression used to give advice. The result clause uses "would + base verb": would look.

He less stressed if he worked fewer hours.

Correct answer: would feel

Second conditional result clause: "would + base verb". "Worked" (past simple) in the if-clause confirms this is second conditional — an unreal present scenario.
