Nice try! Here is a correct sentence you can use:
A tiger's eyes are sharp at night.
Or another simple version:
Tigers have sharp eyes at night.
Why these are correct (easy words):
- "A tiger's" means "belonging to one tiger." We add 's to show something belongs to the tiger.
- "Eyes" is plural because a tiger has two eyes.
- "Are" is the right verb to use with a plural word like "eyes."
- "Sharp" is the describing word (adjective) that tells how the eyes are — they can see very well.
- "At night" tells us when the tiger can see well.
Say it out loud: "A tiger's eyes are sharp at night." Great job!
