I am still confused with English articles ("a", "the")...
I try to teach my little son English, so first I give him the simple sentences. And I've realized that I don't know whether I should use any articles in such kind of sentences. Plz, inject the proper articles wherever needed (given that the sense of the sentences is very general).
1. We live in (?) city.
2. We live in (?) flat.
3. (?) fish lives in (?) sea, and (?) bird lives on (?) tree.
4. (?) lemon is yellow, and (?) tomato is red.
5. What color is (?) lemon?
6. What color is (?) sky? What color is (?) snow?
7. (?) sky is blue, and (?) snow is white.
