To complete the text about bats, you'll need to choose the correct words for the blanks based on context. Here are some suggestions for each blank:

1. **(1)** "or"
2. **(2)** "them"
3. **(3)** "their"
4. **(4)** "at"
5. **(5)** "find"

So the completed text would read:

"Bats are small animals that can fly. There are many different kinds of bat and they live in many parts of the world. Some live in jungles, some live in trees **or** inside houses, but you don’t often see **them**. Most bats sleep in the day and only fly at night. Bats can’t see very well with **their** eyes, but they are all very good **at** flying. They can fly very quickly. Small bats sometimes eat mice, but bigger bats often eat fruit and drink juice that they **find** in flowers."

I hope this helps!
