结合教学实例，论述启发性教学原则。
（1）启发性教学原则的含义：教师要充分调动学生学习的主动性、积极性，引导他们生动活泼地学习，使他们经过自己的独立思考，融会贯通地掌握知识，提高分析问题和解决问题的能力。
（2）贯彻此原则的基本要求：
①教师要钻研教材，充分了解学生，因材施教。
②启发学生独立思考，发展思维能力。
③循循善诱，调动学生学习的主动性。
（3）结合实例论述。
无论是教学原则，还是德育原则，在要求论述时有三步：第一，含义；第二，贯彻这一原则的基本要求（考生一定要把“基本要求”的几个大标题准确记住）；第三，结合实际论述。
在教学原则部分，较容易出现三类考题：
第一类是论述题，如本题。
第二类是简答题，如，“中小学常用的教学原则有哪些?”答案：主要有：科学性与教育性相结合原则，理论联系实际原则，直观性原则，启发性原则，循序渐进原则，巩固性原则，因材施教原则。
第三类是选择题，如《学记》中的“不陵节而施”（体现循序渐进的原则）、“学不躐等”（体现循序渐进的原则）、“道而弗牵，强而弗抑，开而弗达”（体现了启发性教学原则）等都体现了什么教学原则。

My boyfriend really enjoyed canoeing (划独木舟), and it took me a while to finally persuade himto take me on a canoe trip. Despite his great skill, he was nervous about my safety and described manyterrible situations that could happen. "They could also not happen," I said. I wanted to prove that I wastough and capable of adventuring.?
This would be a romantic adventure. We would row the canoe on the lake under a beautiful bluesky. I was confident it would all go according to plan.?
It did not go as planned. Instead,?it all went downhill. We hit a headwind (逆风). The flies werethe worst. An unknown animal outside our tent in the night forced us to get up twice to scare it away.We walked through knee-deep mud; we moved around so many fallen trees that we lost the wayfrequently. We had an unexpected thunderstorm on our second night. We hid in our tent from the bugs(虫子), too tired and bitten to even hold each other. When we were finally back in the car, my skinwas hot and angry with bug bites, I had barely slept in 72 hours and I had an injury on my forehead fromhitting it on the canoe.?
Yet I realized that I wanted to do it all again. Because I swam in a lake so warm it felt like asummer pool. ?I ate lunch on an island with the most beautiful pine trees. ?I' d also never beforeappreciated how thunder can make the ground tremble. I know why my boyfriend loves canoeing somuch. It' s for the challenge, the space, and the beauty of moving forward with your own two hands ina place of natural wonder. He didn' t say "I love you. " He said I was a good partner. I' ve foundsomething that I really like to do. That' s the more important thing.?
