      Many people say dolphins are very intelligent (聪颖的). They seem to be able to think, understand, and learn things quickly. But are they c   1.    like humans or more like cats or dogs? Scientists say dolphin intelligence is s   2.    to human intelligence in some ways. How?

      Like humans, every dolphin has a “name”. I   3.     is a special whistle (哨声). Scientists think dolphins, like people. “t   4.   ” to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans, dolphins use a system (系统) of sounds and body language to c   5.   . But understanding their conversations is not easy for humans. No one “speaks dolphin” yet, but some scientists are trying to learn.

      Dolphins are also social animals. They live in groups, and they often come to play games from different groups and have f  6.    , just like people. In fact, playing t  7.    is something only intelligent animals do.

      Dolphins and humans b   8.     make plans to get something they want. In the seas of southern Brazil, dolphins use an interesting way to get food. When fish are n   9.    a boat, dolphins signal (发信号) to the fishermen to put their nets (网) in the water. And the men can catch a lot of fish. What is the advantage for the dolphins? Why do they h   10.    the men? The dolphins can get some of the fish.

I didn’t think I had a passion(激情). I would sit in front of the TV all day, thinking about nothing but the next show.

It was not long ago that I first learned how important having a passion is to life.

On that day I went with my mum to drive my sister to the gym. I was bored. Then, as my mum stopped at a red light, s 1. on the side of the road caught my eye. It was a man dressed in rags (衣衫褴褛). He was homeless. That didn’t interest me, for I had seen many like him b2. .

But in some ways he was d 3. . This man was not sitting down with a sad expression. He had a radio in his hand and was dancing h 4. to the music. The radio seemed to be the most precious(珍贵)thing he had.

“ Mum, why does that man have A、radio even thought he’s homeless?” I asked.

“He bought it,” she replied.

“But if he’s homeless, why doesn’t he use the money to buy food or clothes? He w 5. it on something he doesn’t need.”

“Well, Sarah, sometimes food and clothes aren’t the most important things. We need happiness, too.”

That man must c 6. enough music to buy a radio instead of food or clothes. I soon realized that happiness is the k 7. to life.

Without it, there’s nothing to look forward to. A passion gives a person the happiness they need to keep going.
