儿童英语读物 The Mystery of the Hidden Beach CHAPTER 4 Petting a Shark

（单词翻译）

“So that’s why they call them parrot fish!” Violet said excitedly a few minutes later. Melanie and the Aldens were peering into a large tank at the Key West Aquarium¹ where a dazzling fish zipped through the crystal-clear water. It was brightly colored and had a beak² almost like a bird’s.

“Parrot fish use their beaks³ to scrape algae⁴ off the coral,” Melanie explained. “Unfortunately, they can leave some pretty bad scars on the reef.”

Jessie steered⁵ them to another large tank, where a young man was giving a lecture. He lifted something dark and wriggly⁶ out of the tank, and held it up carefully in front of the visitors. “This is a nurse shark,” the man explained. “Would anyone here like to pet her?”

Benny’s eyes lit up. “Can I?” When the man nodded, Benny stepped closer and carefully stroked the shark’s side. Then he drew his hand back in surprise. “It feels just like sandpaper!”

“Will it bite?” Violet asked, waiting her turn to touch the shark.

“No, nurse sharks are completely harmless. They’re very gentle,” Melanie told the Aldens.

After they learned about porcupine⁷ puffers and sea cucumbers, the guide lifted a large conch shell out of the tank.

“That’s just like the one you found,” Jessie whispered to Violet.

“I know,” Violet said, admiring the pink and white spiral shell. She wondered who had broken into the classroom building that night, and if the thief would ever be caught. She hoped so.

“This is the horse conch,” the guide was saying. “Maybe he’ll come out for us.” He waited until something large and brown slithered out of the shell.

“There he is!” Benny leaned forward for a closer look.

Everyone watched as the conch inched across the guide’s hand, and then lumbered⁸ slowly back into his shell. “The conch is a very interesting marine⁹ animal. He eats red algae and moves one mile in twenty-four hours.”

“Wow! That’s pretty slow,” Henry pointed¹⁰ out.

Benny giggled¹¹. “Not if you’re carrying your house on your back!” He suddenly spied a pretty blue fish in another tank. “Look,” he said, tugging¹² at Melanie’s hand.

“That’s the fish I told you about. The car-wash fish.”

Melanie nodded. “The blue angel fish,” she said, reading the label on the tank. “You have a good memory, Benny,” she told him. “He cleans up the other fish by eating parasites¹³ off them.”

The same fish that Nick Simon had never heard of, Henry thought.

Later that night over a delicious dinner of fried chicken and mashed¹⁴ potatoes, Benny was telling the whole table about his visit to the aquarium.

“We even saw a barracuda,” he said proudly. “He was swimming really fast underwater.”

Nick Simon smiled at him politely. “They can be very dangerous,” he pointed out. “Just remember to get out of the water if you see one headed your way,” he added jokingly.

“Or better yet, don’t wear any jewelry¹⁵ while you’re swimming,” Melanie said, pointing to a thin silver chain around Nick Simon’s neck.

The marine biologist looked at her blankly. It was clear to everyone that he had no idea what she was talking about. Violet finally turned to Melanie. “What do you mean?”

Melanie shrugged¹⁶. “Everyone knows that barracuda are attracted to things that are shiny. If they see a flash of silver in the water — like a chain — they think it’s something to eat. You see, their favorite food is a type of little silvery fish.” She paused and stared right at Nick Simon. “But then, you know that.”

“Yes, of course,” Nick said quickly. He looked a little embarrassed.

“I definitely don’t want to be dinner for a fish!” Benny exclaimed and everyone laughed.

“Don’t worry, Benny,” Melanie reassured¹⁷ him. “We’ll make sure that you’re not.”

When dinner was over, the Aldens decided¹⁸ to check on their aquariums¹⁹. Jessie had picked up a few pretty, colorful shells at the market and she wanted to add them to the tank.

They were working in the classroom building, when suddenly Benny remembered something. He tugged²⁰ at Henry’s wrist. “Something really strange happened the night we went out in the pontoon boat.” He quickly told everyone about seeing Joshua Slade pluck something out of the ocean and hide it in his shirt.

“He didn’t put it into his bucket the way he was supposed to,” Benny said, confused. “He stuffed it right here.” He pointed to his chest.

“What was it?” Soo Lee asked.

“It couldn’t have been a live fish,” Jessie pointed out, sensibly. “It would have been wriggling²¹.”

“Maybe it was a conch shell,” Violet offered, thinking of her own shell.

“No, that would be too big to fit under his shirt,” Henry said.

“Maybe it was a really pretty shell and he didn’t want the rest of us to see it.” Jessie suggested as she carefully added a sea fan to her tank.

“But what did he do with it?” Soo Lee asked. She glanced at the tank that Joshua Slade shared with his wife. It was almost empty except for a few wisps of sea grass and a couple of angel fish. “He didn’t put it in his tank.”

On the way back to their cabins, they noticed Ned, one of the counselors²², guiding a boat toward the dock. The craft was filled with campers, and Violet remembered that a night expedition was scheduled that evening. Usually boats weren’t taken out at night, but this was a special occasion.

“Let’s see what they got,” Benny said eagerly. “Melanie said you can find some nice fish that only come out at night.”

They were almost at the water’s edge when they spotted²³ Joshua Slade strolling by. He seemed lost in thought and was startled when Ned tossed him a line from the boat. “Would you mind tying that for us?” Ned asked.

“Sure, I . . . I’ll be glad to.” Joshua Slade looked helplessly at the line in his hand, and looped it uncertainly around the piling. “There you go,” he said brightly, and hurried off.

When Ned leaped nimbly off the boat, he looked at the line and shook his head. “What kind of knot is this?” Henry heard him mutter. “The guy doesn’t know how to tie up a boat!”

“Did you hear that?” Henry asked as soon as they were out of earshot. They were walking down the winding²⁴ path that led to the cabins.

Jessie nodded. “Mr. Slade is supposed to run a sailing company, but he doesn’t know how to tie a knot?” She paused. “That doesn’t make any sense at all.”

“A lot of things don’t make sense,” Violet added. “Mr. Simon is supposed to be a marine biologist, but he didn’t know that barracuda like to eat little silvery fish. Melanie had to explain it to him.”

“And he didn’t know about the car-wash fish,” Benny reminded her.

“That’s right,” Henry agreed. “And now look at Mr. Slade. I never heard of a sailor who couldn’t tie a simple knot!”

They were at the girls’ cabin, and Violet stopped outside the door. “I’m beginning to think that Melanie is the only person around here who really knows everything she’s supposed to.”

“She sure does,” Benny said enthusiastically. “I like her a lot!”

“We all do,” Jessie said. “Time to turn in, little brother. We have a big day tomorrow.”

“I know,” Benny said, dancing down the path to the boys’ cabin excitedly. “Windsurfing at eight, sailing at ten, and snorkeling at two.”

“Aren’t you forgetting something?” Henry said teasingly.

Benny thought a moment, then shook his head. “I don’t think so.”

“Breakfast at seven!”

Benny grinned and rubbed his stomach. “I could never forget that!”

The next morning, Benny raced through the cafeteria line so he could be the first one to try the wind-surfing simulator. It was a wide flat board, mounted on a giant spring. If you stepped on the board and shifted your weight, you felt just like you were bouncing back and forth²⁵ over the waves. “It seems funny surfing on dry land,” he said, as he hopped²⁶ on the machine.

“You won’t think it’s so funny if you land on your bottom,” Melanie told him. “The beach sand is nice and cushiony. It will break your fall.”

“I won’t fall,” Benny said.

“Maybe not.” Melanie positioned his feet on the board. “But nine out of ten people do. It’s a lot harder than it looks.”

For the next ten minutes, Benny practiced balancing on the board and working the sails. “Wow, this is hard,” he said, tugging the sail in one direction, then another. “But it must be lots of fun when you finally try it in the ocean.”

“It’s a lot of fun,” Melanie promised. “But we have to make sure you do it safely on land first. And once you’re on the water, you’ll be wearing a life jacket. That’s in case you tumble into the water,” she said. “Not that I think you will.”

Each of the Aldens took turns, and Jessie caught the hang of it right away. “When can we try the real thing?” she asked, her face flushed with excitement.

“I know you think you’re ready to go right now, but you still need some more practice,” Melanie said firmly. “I want everybody out here for half an hour every day, because you can’t try it in the ocean until you master it on land.”

“Oh no!” Benny groaned²⁷.

“It’s not easy,” Melanie pointed out. “But if you practice hard, we’ll try to get you on the water, Benny.”
