    Many students think that learning a new language is very difficult. But if your brain (大脑) is only the same size as a bird's, you will know how difficult it is to learn English. That is what some birds can do.

Many birds can copy (模仿) the sounds of language. A type of African parrot is very good at doing this. This kind of parrot has grey feathers and people say they are clever.

Every December in London, the National Cage and Aviary Bird Show tries to find the best "talking" bird in the world. One bird named Prudle stood out (突出) among the " talking birds"  by winning this prize every year from 1965 to 1977. In 1958, somebody took Prudle from his nest in Uganda, and then sold it to a woman named Iris Frost. She then took care of him at her home in Seaford, England. Before he died in 1994, aged 35, Prudle knew almost 800 words in English. Prudle was also the oldest bird in the world that lived in a cage.

Another parrot named Puck was tested in 1993. It turned out that Puck knew even more words than Prudle. Puck knew more than 1,700 English words. In the 2003 Guinness Book of World Records, Puck was listed as knowing more words than any other bird in the world.

It was half past seven on Monday morning: time to get ready for school. Jay Stone rolled out of bed. He did a couple of quick wake-up exercises and then he went over to his mirror (镜子) and looked at himself.

"Not bad, Stone, not bad," he said to himself and smiled. Maybe he wasn't ready for Hollywood, but with his dark brown eyes and his thick brown hair, he had the looks that turned girls' heads. He moved closer to the mirror and smiled, checking his teeth.

"Perfect," he thought. "Good enough for a toothpaste ad."

As his eyes moved down to his strong arms, he smiled again. The hours he spent in the gym and doing sit-ups have paid off.

But suddenly, the smile froze. His eyes moved from the upper part of his body down to his legs. His legs were short. Not just short, but far too short for his body. He had the upper body of a six-footer, but because of his legs he was much less than six feet! Six inches less! Sitting, he was as tall as almost anyone. Standing, he had to look up at most of the boys and even many of the girls.

Why didn't his legs grow with the rest of his body? He was one of the shortest boys in his class. He was the shortest in his own family, he was even shorter than his "little" sister—by three inches! Where did his legs come from?

He certainly didn't get them from his parents. They were both quite tall. Looking through old family photos, he found the answer. It was his grandfather on his mother's side. His short legs were a gift from Grandpa Tuttle.

Thanks a lot, Grandpa!

Of course, the kids at school all noticed Jay's short legs and they had a nickname (外号) for him: Stubs! Almost no one called him by his real name; they all called him Stubs. Stubs Stone, Jay didn't like his nickname, but he had to accept it. He had no choice.

But Jay couldn't see in the mirror what his legs could do. They were quick and strong. He was the youngest player on the Brewer High football team. He could run faster than anyone else in the team and, like a rabbit, he kept going and going. Even at basketball, where the other players were much taller than him, they were still afraid of him because of his speed.

Jay shook his head. "Stubs, Stubs Stone, the kid with stubby legs. Yeah, that's me," he said to himself with a little smile. Suddenly, he heard his mother's voice.

"Jay! It's breakfast time!"
