Unit 5 Section Ⅰ　Starting out & Understanding ideas(word教参)-【优化探究】2021-2022学年新教材高中英语选择性必修第三册配套教参（外研版）

At the parking area, after putting on our snowshoes, we studied the map.Due to the geographical location, electrical devices are inaccessible here.The map is our only guide.“We start here，” Dad said, “on the red trail (小路)．Then we turn left onto the purple road.That's where Giant Rock is.” “Remember to stick together and don't wander off, guys，” Uncle Don said. The trail ran uphill alongside a stone wall.It was easy to follow because red markers were nailed to the trees and the snow had been packed down by other hikers.At the top of the hill, we turned onto the purple trail.We settled into a pattern, with Dad and everyone else in front and me in the back, crunching (嘎吱嘎吱地踩) through the snow.I saw lots of animal tracks—mostly deer, squirrel, and rabbit prints.As the trail wound down, my cousin Andrew said what I'd been thinking：“ Will we ever reach Giant Rock？” My cousin Aiden smiled and turned to me, “Luke, do you think your Dad invented this idea just to get us away from the TV for a while？” I laughed.“You never know.” Finally, we climbed a hill and saw the massive boulder sitting alone in the forest.It really is as big as a house! My cousins and I high­fived each other and jogged until we stood at the base, breathless.Standing in the boulder's broad shadow, I noticed the sun had sunk lower. “Let's head back，” Dad said after a few minutes.“There will be several crossroads on the way back.Guys, keep up with the team.” Soon we were crunch­crunch­crunching our way home. I was a little behind the group when we approached a crossroads.And I noticed a set of animal tracks I didn't recognise, so I followed them for a closer look. 注意：续写词数应为150左右。 I looked up when I suddenly realized how quiet it had gotten.
