Translation:If they were to walk, they would see the beautiful environment
This sentence is missing an article, either "the" or "a," before "beautiful."
It doesn't give me the chance to report the missing article. No "The English sentence sounds unnatural" Grr.
Articles, articles - come on duolingo get some native speakers on the case.
i think it is even possible without any article, but i am not a native speaker
Native speaker of (American) English here. If the singular "environment" is used then an article is required: ... see a/the beautiful environment. However, if the plural word "surroundings" is used, then you have a choice of no article or definite article: -- see beautiful surroundings / see the beautiful surroundings. The second choice (with the definite article) still sounds better to me.
