摘要： How do the emperor penguins spend their years? A. They give birth during the cold winters in Antarctica. B. They spend half their time on the cold Antarctic ice and the other half in the water. C. They can swim in the cold water in Antarctica. D. They fly up in the sky like other birds in Antarctica. D Three kids have been learning chemistry for only a few months. But they have already begun to challenge a world famous scientist! Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator . They want it to take the place of litmus paper. "We've learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other." British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world. But when the kids did some experiments in class last winter, they saw that the litmus paper didn’t turn very blue with base matter. It's hard to get a clear result. Will there be a better indicator than litmus paper? The three kids decided to try and find out! How? They went to collect over 40 plants in parks, gardens and markets. Then they ground leaves, flowers and stems (茎) to get the pigments from them. The kids mixed pigments with acid and base. They spent months watching carefully to see which paper showed the best colour change. They decided it was the litmus paper! "It's our first scientific journey, Huang said, "But it makes me want to try harder."

Can you think of a bird that can't fly but is a very good swimmer? The emperor penguin is one!
Since last week, six emperor penguins have been on show at the Beijing Pacific Underwater World (太平洋海底世界, BPUW). "I had only seen penguins in my geography textbook," said 13-year-old
Yu Yaxin, when she was watching the birds in the aquarium. "Emperor penguins are much bigger and
taller than I had thought. They're up to my shoulders!"
One month ago these penguins came to China from the Antarctic.
At BPUW, emperor penguins have their own room with a swimming pool! A big air-conditioner helps to keep the room as cold as minus four degrees Celsius.
"They're starting to enjoy their new life now," said Shi Xiaomin, head of the BPUW. "They no longer
hide in the corner when people try to get close to them."
Shi told TEENS that all six were quite lazy. They spend the whole day eating and sleeping. They sleep for more than ten hours a day!
They're not always as nice as they seem. When they get angry, they make loud noises and move their bodies from side to side. They also hit very fast with their hard flippers (鳍状肢).
There are 17 kinds of penguin and the emperor penguin is the largest and also most beautiful of all. Its colourful feathers and lively spirit (气度) made people call it the "emperor" of penguins.
Emperor penguins can swim as fast as 30 kilometres per hour. That's faster than large ships!
In the wild, emperor penguins spend half their time on the cold Antarctic (南极的) ice and the other
half in the water. They're the only birds that give birth during the cold winters in Antarctica. There are now about 570,000 emperor penguins in the Antarctic.
