Write each sentence in the " If ................ Then " form.
A racer wins the race only if he runs fast.

Answer

To convert the statement "A racer wins the race only if he runs fast" into the "If... Then..." form, we can follow these steps:

### Step 1: Identify the Conditional and Conclusion Parts
In the statement provided, we need to identify what the condition is and what the conclusion is.

- **Condition**: The action that must happen first is "a racer runs fast."
- **Conclusion**: The result of this action is "he wins the race."

### Step 2: Formulate the "If... Then..." Statement
Now that we have identified the condition and conclusion, we can structure them into the "If... Then..." format.

- We place the condition first after "If" and the conclusion after "Then."

Thus, we can write:
- **If a racer runs fast, then he wins the race.**

### Final Answer
The sentence in "If... Then..." form is:
- **If a racer runs fast, then he wins the race.**
