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."

Answer the questions（根据短文内容回答下列问题)
Your Nose is Busy and Important
Your nose has many important jobs, and is always busy.
Smelling
Smelling helps you gather information about the world around you. A good scent (气体),like flowers, brings you pleasure. A bad scent, like smoke or sour milk, warns you of danger. Most things around you release scent particles (微粒) into the air. These invisible chemicals enter the nose when you breathe. Nerves in the nose send information to the brain to identify a smell. You are able to recognize thousands of smells.
Breathing
Most of the air you breathe enters through your nose. The nose uses hair and mucus (粘液) to clean dust and germs (细菌) out of the air. The air that enters your nose contains oxygen. Your body uses oxygen to unlock the energy in the food you eat.  Even when you sleep, your body needs energy to keep your heart beating and your brain working.
Tasting
Your nose helps you enjoy food. Flavor is a mixture of taste and smell. The smell of the food helps you identify what you are eating. The sense of smell contributes more to (贡献) food flavor than the sense of taste .When you are sick and have a stuffy nose, your food doesn’t taste as good because without smell, food loses most of its flavor.
Smell memory
Smells can bring back memories. Your brain uses a process to create a picture in your mind from the odors(气味)you smell. Smells can affect your feelings because the part of the brain that helps you identify smells is close to the area that affects your emotions, mood and memory. More smell memories are collected as you get older.
Your nose has many important jobs, and is more than just a smeller!
小题1:How many important jobs does a nose do according to the passage? What are they?
小题2:Smelling helps you recognize thousands of smells, doesn’t it?
小题3:What does the nose use to clean dust and germs out of air?

It is said that the eyes are the windows of our soul. Beautiful and bright eyes not only show a good health but also make you look very attractive. However, to have healthy eyes you have to look after them properly. Your eyes need everyday attention.
Pay more attention to your diet. First, eat food that is good for your eyes. They are fresh fruits and vegetables as fish, eggs, and milk. Besides, a regular amount of vitamins A and B2 should also be taken.
A regular and sound sleep is a must. It relaxes the eye muscles（肌肉）and gives them the rest required. Sleep not only helps the body to repair its tired tissues (组织). Usually, you must sleep for at least seven to eight hours every day. Loss of sleep can give you dark circles under the eye.
You must exercise your eyes every day. Blink (眨眼) yours eyes at regular periods, which makes the eyeballs watery, and gives them a good wash.
We use our eyes in many unnoticeable and wrong ways. Fox example, if a small thing goes into our eye we start rubbing it, which is wrong. Rubbing can cause damage（伤害） to your eyes. Don’t read or write in poor or bright sunlight. Always use sunglasses as sunlight can cause eye tiredness. Light should not shine directly in your eyes. Too much reading, writing, watching television or working on the computer can also cause eye tiredness.
Remember to always take care of God’s most beautiful gift to you. Your life will be very colorless without your eyes.

What is color? Why do some of the things around us look red, some green, others blue?
Colors are really made by deflected (反射) light. We see color because most of the things reflect light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn’t reflect any light, it is black.
Some of the light is reflected and some is taken in (吸引) and turned into (变成) heat (热能).The darker the color is, the less light is reflected, the more light is taken in. So dark-colored clothes are warmer in the sun than light-colored clothes.
小题1:When something reflects light, we can _____.
A．see its colorB．see its heatC．not see its colorD．see nothing
小题2:Something looks white because it reflects _____.
