Passage 6
According to the Center of Disease Control and Prevention (CDC) (疾病控制中心), if you don’t often wash your hands, you can pick up viruses (病毒)from many places and make yourself ill. You’re at risk every time you touch your eyes, nose or mouth. In fact, one of the most common ways people catch colds is by rubbing their noses or their eyes when there are cold viruses on their hands.

After using the bathroom

Before eating, serving or preparing food

After visiting anyone who is sick
When your hands are dirty
There is a right way to wash your hands. Follow these simple steps to keep your hands clean.

Information Card

Shopping is not as simple as you may think! Much has to be done for the producers before putting the products on the shelf.
Color, for example, changes a lot according to what the producers are trying to sell. Health foods are packed in greens, yellows or browns because we think of these as healthy colors.
When some kind of medicine was brought out recently, researchers found that the color of the package(包装) caused the shoppers to lose interest because they made the product look ineffective(无效的). At last, it came on the market in dark blue and white—blue because we think of it as safe, and white as calm.
The size of a package can also attract(吸引) a shopper, although quite often a bottle doesn’t hold as much as it seems to.
It is said that the better-known companies spend about 40 percent of the cost of the product itself on packaging!
The most successful producers know that it’s not enough to have a good product. The head of Pears Soap, who for 25 years has used pretty little girls to sell their goods, came to the conclusion: “Any fool can make soap, but it takes a talent to sell it.”
【小题1】Health foods are usually packed in colors Except ________.

Will it matter if you don’t have your breakfast? There were a test in the US. People of different ages, from 12 to 83, took the test. During the test, these people got all kinds of breakfasts and sometimes they got no breakfast at all. Scientists wanted to see how well they worked after they ate different kinds of breakfasts.
The result shows that if a person eats a right breakfast , he or she will work better than if he or she has no breakfast. If a student has fruit, eggs, bread and milk before going to school, he will learn more quickly and listen more carefully in class.
The result is different from what some people think. It shows having no breakfast will not help them lose weight.(减肥) This is because they become so hungry at noon that they eat too much for lunch. In fact, they will gain weight.（增重） But they will lose more weight if they reduce other meals.

Playing is serious business for children. In fact, it’s what they do best! Ask them why they do it, and kids will probably say, “Because it’s fun!” But it’s much more than that. It’s also good for them.
Studies show that from birth babies begin learning through playing. They use their five senses to get to know their new world. Touching allows them to discover how different things feel. Brightly colored toys and clothing help develop a baby’s sense of sight.
When small children choose which toy to play with, they begin developing their abilities in making decisions. Children love toys that allow them to use their imagination. Sometimes an empty box is more fun than a high-tech toy. That’s because a box can become anything a child imagines it to be.
Crayons, paints and Ply-Doh(彩色塑泥)are also good because they allow children to create. Traditional building blocks teach important pre-math skills like problem-solving.
Playing doesn’t become any less important once children start school. __＊___. Kids learn how to share, take turns and play by the rules.
【小题1】Why is playing a serious business for children?

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.

Early to bed, early to rise, makes a man healthy, wealthy and wise.　　
This is an old English saying. Have you heard of it before? It means that we must go to bed early and get up early in the morning. Then we shall be healthy. We shall also be rich (wealthy) and clever (wise).

Happiness is for everyone. You don’t need to care about those people who have beautiful houses with large gardens and swimming pools or those who have nice cars and a lot of money and so on. Why? Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads at their free time.
In fact, happiness is always around you if you put your heart into it. When you are in trouble at school, your friends will help you; when you study hard at your lessons, your parents are always taking good care of your life and your health; when you get success, your friends will say congratulations to you; when you do something wrong, people around you will help you to correct it. And when you do something good to others, you will feel happy, too. All these are your happiness. If you notice a bit of them, you can see that happiness is always around you.
Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also say you are very happy, because you have something else that can’t be bought with money. When you meet with difficulties, you can say loudly you are very happy, because you have more chances to challenge(向…挑战)yourself. So you can not always say you are poor and you have bad luck. As the saying goes, life is like a revolving(旋转)door. When it closes, it also opens. If you take every chance you get, you can be a happy and lucky person.
【小题1】Those who have big houses may often feel         .

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，设计) of a 3D computer maze(迷宫) 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(无意识的) 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(认为) 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(影响) my life?”
The scientists say there may be ways to use this phenomenon(现象) 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.
【小题1】 Scientists say ______ could help improve your memory.
