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．When I was twelve, I made my first adventures in the deep．Later I would learn how to dive, expanding my world of exploration many times over．
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, 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 courses that summer, I met Dr．Robert Norris, a marine geologist．He loved the sea almost as much as I did．Soon he suggested I consider his school, the University of California, for my study．One year later I became a member of the freshman class．
Now my love affair with the sea became a serious endeavor（艰苦的努力）．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, geology, biology, and many other things．
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 adventures so that we could explore the wonders of the deep．

Ears are for hearing — everyone knows that. But for a creature called the Cuvier’s beaked whale, hearing starts in the throat (喉咙), a new study found.
The observation might help explain how all whales hear. The work might also help scientists understand how animals are affected by underwater sonar (声呐). This sonar, used by some ships, sends out sound waves to locate underwater objects.
The Cuvier’s beaked whale is a so-called toothed whale. Toothed whales dive deep into the ocean in search of food. As the whales hunt, they produce sounds that reach objects and then return to the whales. This allows the animals to “see” the shape, size, and location of objects, even when they’re 1,000 meters under the sea, where it is totally dark.
To better understand how the whale hears, researchers from San Diego State University in California took X rays of two Cuvier’s beaked whales. The whales had died and washed up on the beach.
Ted Cranford and his colleagues used the images to make a computer model of a Cuvier’s b
eaked whale’s head. Then, they modeled the process of sound traveling through the head.
The researchers knew that some sounds get to the ears of a toothed whale through a structure (构造) called “the window for sound”. Found on the lower jaw, this structure is very thin on the outside and has a large pad (垫) of fat on the inside.
When the researchers used their computer model to work out how sound waves travel in the whale’s head, they were surprised to find that sounds coming from right in front of the whale actually travel under the animal’s jaw. From there, sound waves move through the throat, into a hole in the back of the jaw, and finally to the pad of fat near the animal’s ears.
【小题1】Toothed whales look for food under the sea by ______.
| A．watching the shape and size of their objects | B．diving deep into the sea |
| C．sending and receiving sounds | D．making lots of noises |
| A．find out why they had died and washed up on the beach |
| B．make a computer model of a Cuvier’s beaked whale’s head |
| C．make sure that sound travels through the head |
| D．know more about the way the whale hears |
| A．A hole in the back of the jaw → the ears → the jaw → the throat. |
| B．The jaw → the throat → a hole in the back of the jaw → the ears. |
| C．The throat → the jaw → the ears → a hole in the back of the jaw. |
| D．The ears → the throat → a hole in the back of the jaw → the jaw. |
| A．The throat is important to the Cuvier’s beaked whale’s hearing. |
| B．Ships send out sound waves like a Cuvier’s beaked whale. |
| C．The ears are actually useless to the Cuvier’s beaked whale. |
| D．The researchers haven’t found how the whales hear. |

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.
