　　One day Edison sold sandwiches on a train. Suddenly the train was held up in a waste land (荒地) because a railroad bridge had been badly destroyed(毁坏). As time passed, everybody in the train felt hungry, so Edison's sandwiches sold well. When only a few pieces were left, a poor old woman came slowly up to Edison. She searched (寻找) her pockets and then put a warm coin (硬币) in Edison's hand. She took a sandwich and went back to her seat. Four hungry children of hers waited there, all expecting (期望) that sandwich. The woman sat down, tore (扯开) the sandwich into four pieces and gave them to the children.

      Thomas Edison' s lab was badly' destroyed by fire in December, 1914.   1.     Much of Edison' s life' s work went up in flames (火焰) on that December night. After seeing the fire, Edison' s 24-year-old son, Charles, looked for his father among the smoke. 2.    Edison' s face turned red and his white hair blew in the wind.

     "I am happy that he is still alive," said Charles. "He is 67--no longer a young man—and everything is going up in flames. When he saw me, he shouted, "  3.  " When Charles told him he didn' t know, Edison said, “ Find her.   4.   She will never see anything like this. "

     The next morning, Edison looked at the damage and said," There is great value in disaster (灾难). All our mistakes are burnt. We can start again. "

     Three weeks after the fire, Edison showed his first phonograph (留声机 ). To invent something, you need a good imagination and a lot of junk.

 

A. Bring her here. B.’Charles, where' s your mother?' C. Edison stayed in the lab. D. The cost of the damage was over $ 2 million. E. ' Do you know who made the fire?' F. He finally found him and saw that he was quietly watching the fire.

 

 

Three kids have been learning chemistry for only a few months. But they have already begun to challenge (挑战) 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 (酸碱指示剂). They want it to take the place of litmus (石蕊) 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 (研磨) leaves, flowers and stems (茎) to get the pigments (色素) 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."
