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 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."

1.Whom did the three kids want to challenge?

A. Their chemistry teacher.

B. Their headmaster.

C. Robert Boyle

D. Thomas Edison

2.From the text, a red cabbage is a kind of ____.

A. plant  B. animal  C. paper  D. liquid

3.What is widely used as the acid-base indicator now?

A. red cabbage              B. litmus paper

C. any plant                D. any flower 

4.The story mainly tells us ____.

A. how to make litmus paper

B. about the three kids' spirit

C. scientists were wrong

D. the kids are heroes

Perhaps the only test score that I remember is the 55 when I was in high school.
The test was the final for a course. I remember waiting anxiously as my teacher Mr. Right passed out our papers one by one. It was a rather difficult test. I heard my classmates groaning, and I could tel by the groans that the scores weren’t looking good.
Mr. Right put my paper on my desk. There in big red numbers, circled to draw attention, was my score, 55!
I lowered my head, and covered the score up quickly. A 55 is not something that you wanted your classmates to see.“The scores were not very good, none of you passed,”Mr. Right said. “The highest score in the class was a 55.”
A 55. That’s me!
Suddenly my sad look didn’t look so bad. I had the highest score. I felt a lot better.
I walked home alone that day with the low but high score. My father knew that I had a big test that day and asked me as soon as I got home, “How did you do in your test?”“I made a 55,”I said.
A frown(皱眉)now stood on my father’s face. I knew I had to explain immediately. “But Dad, I had the highest score in the calss,”I proudly stated. I thought that explanation would make a difference.“You failed!”my father replied.“But it’s the highest!” I insisted.“I don’t care what scores others had, but you failed. What matters is what you do!”my father firmly said.
For years, my father was always that way. It didn’t matter what others did, it only mattered what I did and that I did it excelently.
We often don’t understand the wisdom(智慧)of good parents until we ourselves stand in the parents’shoes. My father’s words have carried me throughout life.
【小题1】 The word groaning is the closest in meaning to _____.
A.singingB.laughingC.complainingD.quarreling
【小题2】 In class, to hide my score from my classmates, I _____.
A.lowered my headB.covered my score up
C.walked home aloneD.explained immediately
【小题3】 A frown stood on my father’s face because he thought _____.
A.I did a bad job in the test
B.I gave a good excuse
C.I became the worst student
D.I stood in his shoes
【小题4】 We can infer from the passage that _____.
A.the father was strict with his child.
B.the writer was always poor in tests.
C.Mr. Right was worried about the writer
D.the writer was always happy with his scores
【小题5】 Which is the best title of the passage?
A.The Final TestB.That’s Me!
C.My strict TeacherD.Scores, Important?
