[3] 次の英文を読み, 各問いに答えなさい。 [思・判・表] (教科書 P.106~107 参照) (1) Good morning, everyone. Today I am going to tell you about orienteering. Do you know orienteering? Maybe some of you have experienced it. You might think it's like a game in the woods, where you use a map and compass to find some flags. Well, orienteering is also a competitive sport. It started in Sweden, and is most popular in Scandinavia. (2) (3) In an orienteering event, ( ① )competes alone, wearing a running suit that protects them from the weather and the bush. At the starting line, runners start at least one minute apart. When you are told to go, you are given the map for the first time. You then use your compass and the map to find a series of points in the forest. At experienced levels, the points are often far from roads. At each point, there is an orange and white box flag. There, you punch your card. You may not go to points in the wrong order. After all of the runners have passed the finish line, the person with the fastest time in each category of sex and age range is the winner. I tried orienteering once in elementary school, but I'd like to try it someday in a competitive event. Thank you for listening.
