根据短文内容回答问题。(Answer the questions according to the passage．)

　　Mr Wang is a youth worker from the city's youth centre．He gives a speech to the students at No．1 Middle School．Below is what he says．

　　I remember when I was young, my parents used to disagree nearly on everything I did．I liked wearing bright red clothes but they said the color was too sharp．I loved listening to rock and roll but they said it was too noisy．I hated eating vegetables but they said they were good for my health．

　　As for my study, my parents were very strict with me in every subject I was learning．They always asked me to study hard．Every night before I fell asleep, I asked myself,“What's wrong with me? Everything I do is always not right．I had to give up many things I liked doing．I could not develop my hobbies．My life was not as colorful as my friends' lives．”I felt stressed．

　　When I was at college, I studied the science of human activities．I got very good marks but I still did not understand why my parents were so strict．

　　Then I got married and had my own child．I heard myself telling him,“Don't talk on the phone so much! You should focus(集中)on your school work most of your time．Use your free time to read．Playing computers is not good．That T-shirt is not for your age．Put on a jacket!”It was at that time that I learned a valuable lesson in my life．I began to understand my parents．They told me what to do because they cared, just like I told my son what to do because I cared．Young people, behind all the advice your parents give you, what they are really saying is,“We care about you and we love you．”

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."

Do you know why different animals or pests (昆虫) have their special colors? Colors in them seem to be used mainly to protect themselves.

　　Some birds like eating locusts (蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops(庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.

If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (猎人). This is because they have the colors much like the trees.

Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid (液体)when it faces danger. While the liquid spreads over (散开), its enemies (敌人)cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.
