Let's look at your sentence and make it even better!
Your sentence: "In winter, a hare’s grey fur turn white to make it harder to spot on the snow."
Here is the correct version: "In winter, a hare’s grey fur turns white to make it harder to be spotted on the snow."
Explanation:
- We use "turns" instead of "turn" because the subject "fur" is singular, so the verb needs an "s" at the end.
- We say "to make it harder to be spotted" to explain that the hare is harder to see.
So, the improved sentence is: In winter, a hare’s grey fur turns white to make it harder to be spotted on the snow.
