My hometown has changed a lot - it's defintely not (1) the same as it was before. It's not (2) as quite as it was 5 year ago. It' much more noisy, but I prefer it now. There are more shops and restaurants. The restaurants are (3) different from the ones we had before. Now we can eat many different kinds of food - Italian,French,and even Mexican!
