Original: Tundra trees are dwarf trees. They keep close to the ground to hide from the frost and wind.
Corrected (two good options):
- Separate sentences: Tundra trees are dwarf trees. They stay close to the ground to hide from the frost and wind.
- One sentence: Tundra trees are dwarf trees that stay close to the ground to hide from the frost and wind.
Why this is better (easy steps):strong>
- "Keep close" is a little awkward here. We usually say "stay close" when something remains near the ground by itself.
- "Keep" often needs an object (for example, "keep warm"). That makes "keep close" sound odd without something being kept.
- Both corrected versions have good grammar and clear meaning. You can also use simpler words like "cold" instead of "frost": "...to hide from the cold and wind."
Short tip: Use "stay close" when something stays near a place (like trees staying close to the ground).
