VII. Read the following passage and circle the letter A, B, C, or D to indicate the correct answer to each of the following questions. If you want to take the whole family on holiday, and keep everybody happy, then I have found just the place for you. I recently went with a group of friends to stay at the Greenwood Holiday Village, which is open from May until October. Built in the centre of a forest, Greenwood is a great place to stay whatever the weather. Its main attraction for the families is the indoor World of Water, where young and old can have fun in the different pools. Some of these, however, are for serious swimmers only. For sporty people, the Country Club offers tennis, squash and badminton. If your children are too young to join in these sports, there are activity clubs. Greenwood is a good place for families as it is traffic-free-you explore on foot or by bike. Some people complained that this was inconvenient, but I was pleased to be out in the fresh air. For evening entertainment, there are shows and cinemas. Accommodation is in a variety of apartments of different sizes. These have up to four bedrooms, a kitchen and a bathroom, as well as a dining area. Before going, I thought the apartments might not be big enough for all of us, but I was pleasantly surprised-it was not too crowded at all. Visit their website for further information now! 1.
