What is the First Conditional?

The First Conditional is a grammar structure we use to talk about things that are possible in the future. It connects a condition (something that might happen) with a likely result.

It is not 100% certain that the condition will happen, but there is a real chance. If the condition is met, then the result is probable.

• If you study hard, you will pass the exam. (Studying hard makes passing the exam a real possibility.)

How Do We Form the First Conditional?

The First Conditional has two main parts: the 'if' clause and the main clause. We use different verb tenses in each part.

• The 'if' clause (the condition): This part starts with If and uses the present simple tense. For example: If I have time..., If she studies...
• The main clause (the result): This part uses will （或 won't for negative) followed by the base form of the verb. For example: ...I will help you., ...she will pass.

You can put the 'if' clause first or second:

• When the 'if' clause comes first, we use a comma: If it's sunny, we'll go to the park.
• When the main clause comes first, we do not use a comma: We'll go to the park if it's sunny.

When Do We Use the First Conditional?

We use the First Conditional in many everyday situations to talk about future possibilities:

• To talk about future plans or decisions:
  If I finish work early, I will go to the gym.
• To make predictions about the future:
  If the weather is good, the party will be fun.
• To give warnings or threats:
  If you don't hurry, you will miss the bus.
• To make promises:
  If you help me, I will buy you a coffee.

Can We Use Other Words Instead of 'Will'?

Yes, sometimes we can use other modal verbs in the main clause instead of will to express different meanings:

• 使用 can to talk about ability or possibility:
  If you need help, I can assist you.
• 使用 may 或 might to talk about less certain possibilities:
  If it rains, we might stay inside.
• 使用 should to give advice:
  If you feel sick, you should see a doctor.

示例

• If I save enough money, I will buy a new phone.
• She will be happy if you visit her.
• If it snows tomorrow, schools will close.
• They won't win the game if they don't practice.
• If you touch that, you might get a shock.
• We can go to the beach if the sun shines.

西班牙语母语者常犯的错误

Spanish speakers sometimes make specific mistakes with the First Conditional:

• Using 'will' in the 'if' clause: In Spanish, you might use a future tense after 'si' (if). However, in English, the 'if' clause always uses the present simple for future conditions.
  • 错误： If it will rain, I will stay home.
  • 正确： If it rains, I will stay home.
• Forgetting the comma: When the 'if' clause comes first, a comma is needed to separate the two parts of the sentence. This is a common punctuation error.
  • 错误： If I study I will pass.
  • 正确： If I study, I will pass.
