3. Fill in the gaps in the text below with the expression provided. Then imagine that it is the year 2020 or thereabouts, and you feel like having a small break somewhere nice. There are a number of holiday destinations, but many have irrevocably[4] changed. Now you are at a travel agency, looking for a suitable place to go to for a few days.
