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 color 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 |
C.scientists were wrong |
D.the kids are heroes |

Napping(小睡) after learning something new could help improve your memory--- as long as you dream, scientists say.
They found people who dream about a new task do it better on waking than those who do not sleep or do not dream.
Volunteers were asked to learn the layout(布局,設(shè)計(jì)) of a 3D computer maze(迷宮) so they could find their way several hours later. Those allowed to take a pap and who also remembered dreaming of the task, found their way to a landmark quicker.
The researchers think the dreams are a sign that unconscious(無意識(shí)的) parts of the brain are working hard to process information about the task..
Dr. Robert Stickgold of Harvard Medical School, said dreams may be a marker that the brain is working on the same problem at many levels.
Study tips
Co-author Dr. Erin Wamsley said the study suggests our non-conscious brain works on the things that it deem(認(rèn)為) are the most important.
“Every day we are gathering lots of information and new experiences,” she said. “It would seem that our dreams are asking the question, “How do I use this information to inform(影響) my life?”
The scientists say there may be ways to use this phenomenon(現(xiàn)象) for improving learning and memory. For example, students might be better studying hard before bedtime, or taking a nap after a period of afternoon study.
【小題1】 Scientists say ______ could help improve your memory.
A.dream | B.nap | C.nap and dream | D.nap without dream |
A.Take a nap. | B.Dream a task. | C.Learn about 3D computer. | D.Find their way out of a maze. |
A.They are a sign that parts of the brain is unconscious. |
B.They can help us fall asleep and improve learning and memory. |
C.They tell us how to use this information to inform our life. |
D.They may be a marker that the brain is working on the same problem. |
A.Before bedtime. | B.After bedtime. | C.Before taking a nap. | D.In the afternoon. |

If you have failed in the past to try to make big changes in life, try again now, one tiny step at a time.
Every year it's the same. As December comes to an end, you think about the new year and all the ways you want to improve your life. But as you start to write down your hopes for the new year, you think about the last year. You excitedly write down all the changes you are going to make, but by the end of January those ideas get lost in your busy life.
Here's a suggestion: Forget the too big, hard-to-achieve goals and just think about the small ones. “We often think that we have to do everything in big steps, even though it's so hard for us to reach it.” said Robert Maurer, who recently wrote the book One Small Step Can Change Your Life. “What we try to do is to begin with such a small step that we can’t find any excuse not to do it.”
“Kaizen”, a Japanese word, is used to mean to change behavior and attitudes (態(tài)度). During World War II, American factory managers were able to increase productivity by trying small, continuous improvements instead of sudden changes. After the war, the idea was brought to a rebuilding (重建) Japan. It made Japan develop fast. The Japanese called it “kaizen”, which means “improvement”.
Maurer studied the idea and did some experiments with it. “Kaizen” could possibly help people succeed in doing everything.

A. plan for the last year B. fail to make big changes

3. The underlined part “increase productivity” in the passage means “___________ “.
A. 增加成本 B. 提高待遇 C. 提高生產(chǎn)率 D. 增加出口量
4. The writer of the passage suggests we should ___________ .
A. take a tiny step to achieve big goals
B. make changes at the end of the year
