Three kids have been learning chemistry for only a few months. But they have already begun to challenge (挑戰(zhàn)) 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 (酸堿指示劑). 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 (莖) 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."
【小題1】 Whom did the three kids want to challenge?
A.Their chemistry teacher. | B.Their headmaster. |
C.Robert Boyle | D.Thomas Edison |
A.plant | B.a(chǎn)nimal | C.paper | D.liquid |
A.red cabbage | B.litmus paper |
C.a(chǎn)ny plant | D.a(chǎn)ny flower |
A.how to make litmus paper | B.a(chǎn)bout the three kids’ spirit |

閱讀短文,判斷下列句子是否符合短文內(nèi)容。符合的寫“A”,不符合的寫“B”。(共5小題,每小題2分)
Water is the most important in our lives. Not Many people understand this but it’s quite true. The human body can go without food for a long time. We’ve got many examples for this. Yet two or three days without water can usually make people die. Man can’t live without water.
Many people don’t understand how much water the human body needs to work well, and many people, especially young people, do not drink enough water, even in very hot weather. About two thirds of our body is water. When we do sports, some of the water will get away from our body. If we don’t drink some water, our body won’t have enough water. And if we don’t have enough water, we’ll feel tired and many of us will get ill. So you know how important water is to us.
But at present we face water crisis(危機(jī)). Water is becoming less and less. So, we should protect water resources(資源) and try our best to save water in our daily life. Here are some tips for saving water:
1. Turn off the tap(水龍頭) in lime.
2. Take shorter showers.
3. Don’t let water run while washing your face and reuse the water after we finish washing.
4. Encourage your friends and neighbors to join in the action of saving water.
1.Nobody can live without water.
2.About one third of our body is water
3.If one doesn't have enough water, he’ll feel tired and may get ill.
4.We’d better take longer showers and let water run while washing.
5.It’s our duty to protect water resources and save water.
