There is a passage followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
It was a normal evening when I experienced what felt like a seismic (地震的) event. It didn't shake anyone else's world, but it certainly changed my life and that of my family, possibly forever. I turned to my life with a proposition: "How about we try and get away from it all for a year? Take a break. Revitalize (使有新的活力) ourselves as teachers and the girls as learners? Spend more time together. Go on an adventure!" The idea led to us making a radical decision that left us houseless and jobless, and saw our two daughters, Amy and Ella, being removed from the formal education system.
Our idea was to try to live more for the moment and embark on an educational adventure all together. Lots of families take their kids on road trips to far-off places and distant cultures, but we wanted our adventure to be UK-based. We didn't feel the need to travel abroad to achieve our goals. Our islands have so much to offer: history and geography on our doorstep, and amazing landscapes.
We were on the road, home schooling in a touring caravan (大篷车). We began at Warwick Castle then headed north to Scotland. We ventured into corners of England, Wales, Scotland and Ireland. Our route was varied and a bit random, driven by educational aims.
Through the adventure, we've learned that it builds character but that it also builds strong bonds. Seeing Ella patiently and compassionately help others down a steep section of Ireland's highest mountain and Amy digging deep when paddling Loch Ness in wind and rain confirms our belief that these experiences are life-forming. After more than a year on the road, Amy and Ella now see challenges as an important part of life and value their ability to persevere when the going gets tough.
We're now in year two of our adventure with plans to explore Spain, France and Scotland. None of us wants to stop just yet, so we will probably carry on until the money runs out, it stops feeling right, or one of us invokes the "get me out of here" clause.
