阅读下列材料，并回答问题。
? [材料]马老师在“燃烧与灭火”一课的备课中，反思以往学生在学习该内容时存在的问题，深深认识到“燃烧与灭火”虽然是生活中常见的现象，但仅仅通过课本和几个实验，不利于学生获得丰富完整的体验和认识，难以达成预定的教学目标。于是，马老师在本课的教学中，除讲解相关的知识外，还通过网络图片、动画、视频材料等教学资源，使学生对“燃烧的条件”、“灭火的原理”、“燃烧的利与弊”、“火灾预防和安全救护”、“消防安全标志”、“灭火器”、“火场逃生”等知识有一个全面感性的认识。
最后，组织学生对本课主题进行讨论，使学生既掌握了完全的知识和理论，又开阔了眼界，增强了安全意识，发展了科学素养。
[问题]请依据教学过程的某些规律或教学原则，对马老师的教学进行评析。
答案一：根据多年的教学经验，依据的教学过程相关规律，我认为马老师的教学主要体现了以下几个方面：（2分）
? （1）教学过程中学生认识的特殊性规律。学生主要是通过间接性经验来认识客观世界的，其基本步骤是感知、理解、巩固、运用，其中理解是中心环节；任课老师通过各种直观手段，使学生对“燃烧与灭火”的教学内容，有较好的感性认识，在此基础上，进行理论概括，加深了对内容的理解。（5分）
答案二：根据多年的教学经验，依据相关的教学原则，我认为马老师的教学主要体现了以下几个方面：（1分）
（1）直观性原则。教师不仅进行讲解，而且通过网络图片、动画、视频材料等各种直观手段，使学生对“燃烧与灭火”形成了比较完整的认识与理解。（4分）
（2）理论联系实际的原则。教师在讲授“燃烧与灭火”原理的同时，有机结合生活实际，以直观的形式呈现出来。（4分）
（3）教学的教育性原则。教师还对学生进行了火灾预防和安全救护的教育。体现有思想品德教育的内容。（4分）
通过上述分析发现，我们在教学过程中应该充分把握好直观性原则、理论联系实际原则以及教育性原则等方面，从而能够帮助学生更好地理解基础知识，又能够促进学生提高基本能力。（2分）

What is the main reason for reducing salt in food?
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.?
