Let's check your sentences step by step and make sure the grammar is correct.
Your original sentences are:
Fast rivers, avalanches and deadly rockfalls make life in the mountains hard. Brave mountain goats tackle steep slopes and the snow leopard has thick fur to keep warm.
Here's the grammar check:
- First sentence: "Fast rivers, avalanches and deadly rockfalls make life in the mountains hard."
This sentence is correct! It has a list of things that make mountain life hard, and the verb "make" agrees with the plural subject. - Second sentence: "Brave mountain goats tackle steep slopes and the snow leopard has thick fur to keep warm."
This is a compound sentence joining two ideas with "and". Grammar-wise, it's okay; however, adding a comma before "and" can help clarity: "Brave mountain goats tackle steep slopes, and the snow leopard has thick fur to keep warm."
Final corrected version with a comma added for clarity:
Fast rivers, avalanches and deadly rockfalls make life in the mountains hard. Brave mountain goats tackle steep slopes, and the snow leopard has thick fur to keep warm.
Great job! Your sentences are clear, and with this tiny change, it's even better.
