| In England boys and girls usually have two months to rest after the final exams. Not only the rich but also factory workers or bus drivers can take our children to the seaside for their holidays. Why do children like spending their summer holidays on the seaside? It is because that they like the sand, the cool wind and the salt water there more than anything else. Of course, there are plenty of new things to see, nice things to eat and excited things to do, but it is the feelings of sand under one's feet, of cool wind on one's skin, and of warm sun on one's back that make the seaside what it was. | 1. _____ 2. _____ 3. _____ 4. _____ 5. _____ |
