Here are the correct answers for the gaps:
- B. an (Because "apartment" starts with a vowel sound, so "an" is used.)
- A. but (This contrasts the fact that it’s a big city but not a noisy place.)
- B. are (Referring to "trees and flowers" which are plural, so "are" is correct.)
- D. play (The simple present tense "play" is used for habitual actions.)
- D. opposite (This indicates the cinema is located opposite the supermarket.)
So the completed paragraph would be:
Hello, I'm Erik. If you asked me, I would say my neighborhood is the most beautiful place in my life. I live in an apartment in a big city, but my neighborhood is not a noisy place. There are lots of trees and flowers in a large park. My sister and I often play there after school. There is also a small supermarket to the right of the park. We shop there every weekend. It's really convenient. The supermarket has everything we need. In our free time, my sister and I often go to the cinema opposite the supermarket to see a movie. It's a lot of fun.
