Let's look at the sentence: "An albatross spends most of its life flying over the sea, landing only to eat and to nest."
It is a very good sentence! It tells us that an albatross flies a lot over the sea and only lands to eat and to nest.
The grammar is correct because:
- "An albatross" is the subject (the bird we're talking about).
- "spends" is the main verb, telling us what the bird does.
- "most of its life" tells us how much time it spends doing this.
- "flying over the sea" explains what it is doing during most of its life.
- "landing only to eat and to nest" tells us the only times it lands, adding more information.
So, the sentence is grammatically correct and clear. Good job writing it!
