My love affair with the sea began when I was no more than six years old, walking along the sandy beaches. I always wanted to make the first set of footprints in the wet sand.
Unlike many surfers who sought the perfect wave, my interests always lay beneath the sea’s surface in a world I could only imagine and dream of. Soon, wearing a snorkel and a mask, I made my first solo adventures in the deep.
Perhaps the greatest turning point in my life came when I was in high school and I wrote a letter to the famous Scripps Oceanographic Institution, in San Diego, asking how I might learn more about the sea.
A kind scientist answered my letter and told me how to apply to Scripps for a summer scholarship, which I received. During one of their cruises that summer, I met Dr. Robert Norris, a marine geologist. He loved the sea almost as much as I did. Soon he was asking me what my plans were and where I expected to attend college. I told him I didn’t know, so he suggested I consider his school, the University of California in Santa Barbara.
Now my love affair with the sea became a serious endeavor. If I wanted to be an undersea explorer, I needed to learn as much as I could about the laws of the physical world that controlled the environment I wanted to enter. The undersea world is not our natural world. It is unforgiving to those who make mistakes. At its greatest depths the water temperature is near freezing, the pressure is eight tons per square inch, and it is totally dark. It is easy to get lost in such a world. I needed to learn a lot about geography, navigation, meteorology, geology, biology, and many other things. While I was in school, I took a little of everything.
I decided another important thing for me to do was to join the U.S. Navy. If I was going to be an undersea explorer, I would have to lead men and women on dangerous adventures where they might get hurt, and I didn’t want that to happen. In the Navy I learned discipline, organization, and how to motivate and lead people on expeditions so that we could explore the wonders of the deep.
Finally, the time came to put all that I had learned to use, to go forth with a team of men and women and explore an adventure I am still on and hope to be on for many years to come.

(答案→)A 解析：本文讲述了作者从小就热爱海洋，讲述了自己的人生转折点，告诉那些想学深海探险的学生去学习更多有关海洋方面的知识。【小题1】细节题。从文章At its greatest depths the water temperature is near freezing, the pressure is eight tons per square inch, and it is totally dark.可知此处的水压是物理法则的一方面，故选A【小题2】细节题。从倒数第三段The undersea world is not our natural world. It is unforgiving to those who make mistakes. 可知作者认为他要学习这些知识是因为要理解好海洋这些知识是必须具备的，故选D【小题3】细节题。从文章In the Navy I learned discipline, organization, and how to motivate and lead people on expeditions so that we could explore the wonders of the deep. 可知作者是要培养自己的组织领导能力，故选A【小题4】细节题。从倒数第二，三自然段可知，作者作者推荐那些想要深水探险的学生去学习更多有关海洋方面的知识，故选D

这个解释是对的
