The H1Nl virus has been spreading world-wide,it is important for us to know how to control it.Please pay attention to the following points:
1.Don't touch your face.Above all,keep your hands away from your eyes,mouth and nose,all of which serve pathways(途徑) for the viruses(病毒) to enter your body.
2.Wash your hands.If you have to touch your face,wash your hands,getting under the fingernails for 20 to 30 seconds with hot soap and water before.Soaps with surfactants(表面活性劑) can deal with flu viruses.
3.Cover your nose and mouth.When someone sneezes or coughs,liquid(液體) drops with flu viruses as far as three feet through the air and land on your nose and mouth,so it's best to keep at least an arm's length distance when talking to someone who shows signs of infection(感染).In order to protect others,cover your mouth and nose with a tissue(紙巾) when you cough or sneeze,and clean your hands afterward.Viruses can live for hours,or even longer when on the skin or other surfaces such as keyboards.
4.Consider buying a mask in case you need it in the future.Some research suggests that masks reduce the risk of getting the flu viruses by as much as 80%.But it also suggests that if you don't wash hands,the mask doesn't work well.So wash your hands and use the mask,especially wearing face masks in crowded places is also useful.

Have you ever rubbed your hands together when they get cold? Why do we do that? We do that for friction. Friction happens when two things that aren’t very smooth (光滑的) rub together to make heat energy. The faster you rub two things together, the more friction you can make. Let’s discover friction!

WHAT YOU’LL NEED:
★Soap                ★Water           ★Your hands
WHAT TO DO:
★Make sure your hands are dry.
★Rub your hands together until you feel the heat of your hands.
★Now, use soap and water to get your hands very slippery (滑的).
★Try to make friction happen while your hands are slippery.
★Please write down what has happened.
LET’S TALK!
Friction is an energy that happens when two things rub together. When friction happens, it makes heat! When your hands are slippery, they won’t make very much friction and your hands won’t get so hot.
DID YOU KNOW?
★Friction happens when you stop your fast running bike.
★Ancient people made fires by rubbing two pieces of wood together. Friction happened though they didn’t know it. ___  __?         Friction is everywhere. Have you ever noticed situations where friction is happening? If not, ask your parents to take you out in a car. If it is not hot, touch the tires (輪胎) of the car before and after a short drive to see how much warmer they get from friction.

You change the channels for the fourth time and realize that once again there’s nothing on television that gets your attention. Not a problem! Throw on some running shoes and comfortable clothes and go for a run.
One of the coolest things about the sport of running is that you don’t need expensive equipment(裝備). All you need is a good pair of running shoes and a safe environment. But just because you don’t need much equipment don’t be fooled into thinking the sport of running is easy. No one wakes up and decides to run a marathon without training.
Running makes your heart, lungs, and muscles stronger. It makes you know more about your body. Running also gives you energy by increasing your oxygen(氧氣) intake, so you don’t get sick easily. It can even help you keep your mind on school work because exercise helps you to think more clearly.
How do you take part in the sport if you don’t know much about it? Most schools offer cross-country and track programs, but there are also running clubs open to all ages. A simple Internet search can help you find some in your area. The programs show you how running can offer competition or just be for fun. They also teach runners to set realistic goals and take care of their bodies.
Runners have great respect for each other because they know how difficult the sport can be. If you go to a race, you’ll see people cheering for all the runners, from the first place finisher to the last place finisher. Running isn’t always about how fast you are or how far you’re going. It’s about getting out there and doing it. Taking part is more important than competition, and effort is recognized over gift.
If you’re looking for more than just a sport, running may be the perfect choice for you.
小題1:Which of the following is true?
A.Running helps you win a marathon.
B.Running helps you improve your study.
C.Running helps you think more about yourself.
D.Running helps you set realistic goals in your life.
小題2:What is the most important for runners in a race?
A.Having fun.B.Receiving respect.
C.Trying their best.D.Winning the competition.
小題3:What is probably the best title for this passage?
A.Running and Runners
B.Running: Easy or Difficult
C.Running and Watching TV
D.Running: a Sport or a Way of Life

Most of the things around you will be replaced or thrown away someday. Where will they go when they are thrown out? What kinds of waste will they create, and how will it affect the environment
Most of our crash goes to places called landfills. A LANDFILL is a low area of land that is filled with garbage(垃圾).Most modern landfills are lined with a cover of plastic to keep dangerous liquids(液體)from polluting earth and ground water supply. The problem is that more than half of the states in this country are running out of places to landfill their garbage. Because of the unhealthy materials, landfills do not make good neighbors,and people don’t want to live near them. Many landfills are set in poor neighborhoods.
The Fresh Kills landfill on Staten Island, New York, was the largest garbage landfill in the world. For years, people who live nearby complained about air and water pollution caused by the enormous pile of trash. They say that the smoke have made people sick. The landfill closed in
April 2001.Now can a harmful waste—material that can pollute air, land, and water –be disposed of in a safe way.
Another way to get rid of trash is to burn it. Trash is burned in an incinerator._ Because incinerators in operation can get rid of almost all of the trash, some communities would rather use incinerators than landfills. There is a problem, though. Leftover ash and smoke from burning trash may have dangerous chemicals, and even make it hard for some people to breathe. They can harm plants, animals, and people.
You can help reduce(減少)waste by reusing bottles, batteries, and paper. You can also recycle newspaper, glass, and plastics t to provide materials for making other products.
From recycled materials, many things are made. For example, from recycled paper we can get newspapers, boxes and so on. From recycled plastic we can get soda bottles, tables, and backpacks.
小題1:Why don’t landfills make good neighbors?
A.Because there are unhealthy materials in them.
B.Because people prefer to live in the city center.
C.Because landfills are not big enough for trash.
D.Because most states are running out of places.
小題2:What does the underlined word “incinerator”_probably mean?
A.An area to collect trash.B.A machine to burn trash
C.A method that is used to burn trash.D.A station that is run by selling trash.
小題3:What is probably the best title for the passage?
A.How Is Trash Burned?B.What Can Be Reused.
C.Why Is Waste Dangerous?D.Where Does Garbage Go?

Hello ,everyone!
Thank you very much for coming to this concert. I hope you have enjoyed the performance. As you may know, all the performers have given their time to help us.
This concert is to raise money for children in Africa. Every day hundreds of children in Africa die because they don’t have enough to eat. There are two reasons. First, there is no work for the children’s parents. Second, the governments in many African countries do not have the money to help the poor.
Most African countries are poor. The land is not good for growing food and the weather is also bad for farming. The Feed Africa Fund spends millions of dollars every year on food for poor people in Africa. This money comes from people like you---- kind, generous people who do not want to see children die from hunger.
Every dollar you give this evening will go to the Feed Africa Fund. Just one dollar can buy enough food to feed a family of four for three days. Think about it: only one dollar can feed four people for three days.
How much do you spend on food every day? Ten dollars? Twenty dollars? I am sure you can spend a little less on your own food so that you have a few dollars for the Feed Africa Fund.
Please be kind and generous! Give your money with a helping hand. Your money can make a difference in others’ life and yours. Thank you!
