One day in 1963, a dolphin named Elvar and a famous astronomer, Carl Sagan, were playing a little game. The astronomer was visiting an institute which was looking into the way dolphins communicate with each other. He was standing at the edge of one of the tanks where several of these highly intelligent, friendly creatures were kept. Elvar had just swum up alongside him and had turned on his hack. He wanted Sagan to scratch his stomach again, as the astronomer bad done twice before. But this time Elvar was too deep in the water for Sagan to reach him. Elvar looked up at Sagan, waiting. Then, after a minute or so, the dolphin leapt up through the water into the air and made a sound just like the word 'More!'
The astonished astronomer went to the director of the institute and told him about the incident. 'Oh, yes. That's one of the words he knows,' the director said, showing no surprise at all.
Dolphins have bigger brains in proportion to their body size than humans have, and it has been known for a long time that they can make a number of sounds. What is more, these sounds seem to have different functions, such as warning each other of danger. Sound travels much faster and much further in water than it does in air. That is why the parts of the brain that deal with sound are much better developed in dolphins than in humans. But can it be said that dolphins have a 'language' in the real sense of the word? Scientists don't agree on this.
A language is not just a collection of sounds, or even words. A language has a structure, or what we call a grammar. The grammar of a language helps to give it meaning. For example, the two questions 'Who loves Mary?' and 'Who does Mary love?' mean different things. If you stop to think about it, you will see that this difference doesn't come from the words in the question but from the difference in structure. That is why the question ' Can dolphins speak?' can't be answered until we find out ff dolphins not only make sounds but also arrange them in ways which affect their meaning.

A．Sagan had turned his hack
B．it was part of the game they were playing

Married people live 'happily ever after' in fairy tales, but they do so less and less often in real life. I, like many of my friends, got married, divorced, and remarried. I suppose, to some people, I'm a failure. After all, I broke my first solemn promise to 'love and cherish until death us do part.' But I feel that I'm finally a success. I learned from the mistakes I made in my first marriage. This time around, the ways my husband and I share our free time, make decision, and deal with problems are very different. I learned, first of all, not to be a clinging vine (依赖男子的妇女). In my first marriage, I felt the every moment we spent apart was wasted. If Ray wanted to go out to a bar with his friends to watch a football game. I felt rejected and talked him into staying home. ! wouldn't accept an offer to go to a movie or join an exercise class if it meant that Ray would be home amone. I realize now that we were often angry with each other just because we spent too much time together. In contrast, my second husband and I spend some of our free time apart and try to have interests of our own. I have started playing racquetball at a health club, and David sometimes takes off to go to the local auto races with his friends. When we are together, we aren't bored with each other, our separate interests make us more interesting people. I learned not only to be apart sometimes but also to work together when it' s time to make decisions. When Ray and I were married, I left all the important decisions to him. He decided how we would spend money, whether we should sell the car or fix it, and where to take a vacation. I know now that I went along with this so that I wouldn't have to take the responsibility when things went wrong. I could always end an argument by saying, 'It was your fault!' With my second marriage, I am trying to be a full partner. We ask each other's opinions on major decisions and try to compromise ff we disagree. If we make the wrong choice, we're equally guilty. When we rented an apartment, for example, we both had to take the blame for not noticing the drafty windows and the 'no pets' clause in our lease. Maybe the most important thing I've learned is to be a grown-up about facing problems. David and I have made a vow to face our troubles like adults. If we're mad at each other or worried and upset, we say how we feel. Rather than hide behind our own misery, we talk about the problem until we discover how to fix it. Everybody argues or has to deal with the occasional crisis, but Ray and I always reacted like children to these stormy times. I would lock myself in the spare bedroom. Ray would stalk out of the house, slam the door, and race off in the car. Then I would cry and worry till he returned. I wish that my first marriage hadn't been the place where I learned how to make a relationship work, but at least I did learn. I feel better now about being an independent person, about making decisions, and about facing problems. My second marriage isn't perfect, but it doesn't have the deep flaws that made the first one fall apart.Which of the following has contributed to the writer's divorce?A．Her former husband went out to watch football games.B．She started to play racquetball at a health club.C．They spent too much time together and got bored with each other.D．They spent so little time together that they could not talk to each other.
