As A/H1N1 continues to spread, experts from the Centers for Disease Control to the World Health Organization to neighborhood doctors are calling on the people to practice smart flu prevention techniques. Here are some tips to keep body improved and immune(免疫)system ready to fight infection.
Wash Your Hands
And wash them often, in hot soapy water, and for the amount of time it takes you to sing “Happy Birthday” twice.
Get Enough Sleep
This means slightly different things to different people, but try to get 8 hours of good rest each night to keep your immune system in top flu-fighting shape.
Keep Hydrated
Drink enough water each day to clear poisonous matter from your system and keep up good moisture(濕度)production in your body.
Eat Immune-Improving Foods
Keeping you body strong and ready to fight infection is important in flu prevention. Fatty foods can slow your metabolism(新陳代謝), make you feel inactive, and weaken your immune
system. So stick with whole grains, colorful vegetables, and vitamin-rich fruits.
Avoid Alcohol
Alcohol is likely to decrease your resistance to infections and further damages the immune system. So avoid alcoholic drinks to keep your immune system strong.
—————————————?
Proper exercise-for example walking for 30-40 minutes 3-4 times a week-supports the immune system by increasing circulation, oxygenating the body, removing poisonous material through sweat, and reducing tension and stress. So get moving!
Avoid Contact with Sick People
If you’re coughing or sneezing, cover your mouth(and then wash your hands),and if you have to be around someone who is sick, try to stay a few feet away from them and avoid physical contact.
Know When to Get Help
A/H1N1 can look like regular flu, so don’t feel like you necessarily are infected if you’re exhibiting flu-like symptoms(癥狀). But do go to your doctor if you live in an area where there are recorded cases, or if your symptoms are very serious.
小題1:To fight A/H1N1 infection, it’s helpful for us to_______ .

Watercolour is the oldest paints known. It dates back to the early cave men who discovered they could add lifelike qualities to drawings of animals and other figures on the walls of caves by mixing the natural colours found in the earth with water.
Fresco (壁畫), one of the greatest of all art forms, is done with watercolour. It is created by mixing paints and water and applying these to wet plaster (灰泥). Of the thousands of people who stand under Michelangelo’s heroic ceiling in the Sistine Chapel, very few know that they are looking at perhaps the greatest watercolour painting in the world.
The invention of oil painting by the Flemish masters in the fifteenth century made fresco painting go down-hill, and for the next several centuries watercolour was used mainly for doing sketches (草圖) or as a tool for study. It was not until the eighteenth and nineteenth centuries that English painters put back watercolour as a serious art form. The English have a widely-known love for outdoors and also small private pictures. The softness of watercolour had a remarkably strong attraction for them.
The popularity of watercolour continued to grow until the twentieth century. The United States passed England as the center for watercolour, producing such well-known watercolour artists as Thomas Eakins and Andrew Wyeth.
小題1: The purpose of the passage is to introduce _____. 
A.the gradual weakness of fresco painting
B.oils’ power or influence over watercolour
C.the discovery of watercolour in England
D.the start and development of watercolour
小題2: In the 16th and 17th centuries the artists thought _____.
A.watercolour was softer, and thus better
B.oil painting lasted longer, and was better

Ask someone what they have done to help the environment recently and they will almost certainly mention recycling.Recycling in the home is very important of course.However, being forced to recycle often means we already have more material than we need.We are dealing with the results of that over–consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.
The total amount of packaging has increased by 12% between 1999 and 2005.It now makes up a third of a typical household’s waste in the UK.In many supermarkets nowadays food items are packaged twice with plastic and cardboard.
Too much packaging is doing serious damage to the environment.The UK, for example, is running out of it for burying this unnecessary waste.If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect.Recycling helps, but the process itself uses energy.The solution is not to produce such items in the first place.Food waste is a serious problem, too.Too many supermarkets encourage customers to buy more than they need.However, few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.
But this is not just about supermarkets.It is about all of us.We have learned to associate packaging with quality.We have learned to think that something unpackaged is of poor quality.This is especially true of food.But it is also applied to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope.As more of us recycle, we are beginning to realize just how much unnecessary materials are collected.We need to face the wastefulness of our consumer culture, but we have a mountain to climb.
小題1:What does the underlined phrase “that over-consumption” refer to?
A.Using too much packaging.
B.Recycling too many wastes.
C.Making more products than necessary.
D.Having more material than is needed.
小題2:The author uses figures in Paragraph 2 to show ___________.
A.the tendency of cutting household waste
B.the increase of packaging recycling
C.the rapid growth of supermarkets
D.the fact of packaging overuse
小題3:According to the text, recycling ___________.
A.helps control the greenhouse effect
B.means burning packaging for energy
C.is the solution to gas shortage
D.leads to a waste of land
小題4:What can be inferred from Paragraph 4?
A.Unpackaged products are of bad quality.
B.Supermarkets care more about packaging.
C.It is improper to judge quality by packaging.
D.Other products are better packaged than food.

“You know, these cups bring to mind a tea quote(說法) I heard.” Mary’s aunt said.
She poured tea. There were four of them and there were four totally different cups on the table.
They took their tea cups.
“What quote?” Mary asked.
“Well, maybe I should rather say it is a story,” aunt said, “I heard that there was a wise teacher who took all his students for tea. They were surprised that all the cups on the table were different. Each of them took a cup and started drinking their tea, each looking at the cups of others. The teacher let them do that for a while and then said,‘ Do you notice your behavior? You are all looking at each other’s tea cup and I can see some of you with the broken ones are even envious(羨慕的) of the finer cups of others. Is this not so?’ ”
The students agreed, amused by their own behavior.
“You may have wondered why you all had different cups, but I put them here on purpose. You see they represent (代表) life itself. Life is like that tea and the cups are like the physical circumstances(狀況) of your life. You all got the same thing in your cups — tea. And yet you can not truly enjoy it in your envy of another’s cup. It’s just the same with life. You forget to enjoy your own life when you concentrate on envying the circumstances of someone else’s life.
So now, close your eyes, and taste your own tea. Really taste it. And tell me — did it matter from which cup it came from?”
Aunt finished telling her short tea story and they all sat in silence for a while, tasting their tea. A sleepy fly buzzed(嗡嗡作響) past, a bird sang in the tree. And it really did not matter one bit from which tea cup they drank.
小題1: When the students found they had different tea cups, they_____________.
A.were satisfied with their own cup

A.the teacher prepared different tea cups for each student

A.should try different ways of life
B.shouldn’t focus on envy others’ physical circumstances
C.can never change their physical circumstances
D.should work hard for a better life
小題4: In the passage the teacher’s message to the students was that _______.
A.life is hard and boring for everyone

Imagine a boy from a small village in East Africa. He, since a very early age, has been looking after cattle. At twelve years old he knows more about cattle than most of you. However, he has never been to school. Has this boy had any education?
Education is discovering about ourselves and about the people and things around us. All the people who care about us — our parents, brothers, sisters, friends — are our teachers. In fact, we learn something from everyone we meet. We start learning on the day we were born, not on the first day we go to school. Every day we have new experiences, like finding a bird’s nest, discovering a new street in our neighborhood, making friends with someone we didn’t like before. New experiences are even more fun when we share them with other people.
Encouragement from the people around us enables us to explore things as many as possible. As we grow up, we begin to find out what we are capable of doing. You may be good at cooking, or singing or playing football. You find this out by doing these things. Just thinking about cooking doesn’t tell you whether you are good at it.
We learn so much just living from day to day. So why is school important? Of course you can learn some things better at home than at school, like how to do the shopping, and how to help old or disabled people who can’t do everything for themselves. At school, teachers help us to read and write. With their guidance, we begin to see things in different ways.
小題1: The writer takes the African boy as an example to show that _______.
A.African children are very poor.B.some children are unlucky.
C.there are many kinds of education.D.schools are of great importance.
小題2:In the opinion of the writer,       .
A.we have to learn from the people around us.B.the school is not important at all.
C.only people who care for us can teach us.D.education takes place everywhere.
小題3: One can find out what he / she is good at by     _.
A.what people encourage him/ her to do.B.the teachings of those he / she meets.
C.thinking about it when growing up.D.trying and practising things.
小題4: The passage tells us that _    .
A.everyone gets education from the day he or she was born.
B.different classes of people receive different kinds of education.
C.the school is absolutely necessary if one wants to understand the world.
D.everyone will find out what he or she is good at.
小題5:According to the last paragraph, we know that       .
A.the school is not so important as our living places.
B.the school enables us to understand the world in other ways.
C.the school teaches us things which are useless at home.

Besides calling 911, here is what to do in some life-threatening emergencies when no oneis

         

 
around to help.

Lost in the wilderness
First, you’ve got to acknowledge you’re in trouble. Stay where
you can be seen clearly and remember to rest. Keeping a sense
of humor helps too—it reduces stress and helps creative thinking.
In a wide open area, make a colorful cross out of rocks to show
your present position.

 

 
Choking

Aim to hit the top of the chair against your stomach, in the soft part
below the bony upside-down V of the ribs(肋骨). Make a sudden
push against the chair. If you still can’t breathe after six tries, call 911,
even if you can’t talk. Write the word choking somewhere nearby, and
leave the line open until help arrives.


 
Severe bleeding

Use your hand or clean cotton, or paper towels, or a scarf,
or any cloth you can find, and push down on the wound
until the bleeding stops. But if you put a band around
your leg tightly, you’re going to close the vessels(血管)
to the entire leg. In this way, you could lose your foot.
Bear attack


 
If you surprise a bear, don’t run away. That invites an attack.

Instead, stand up and back away slowly, without looking the
bear in the eyes. If it does charge at you, stick out your chest,
raise your arms, and spread your legs. Shout at the bear, to
frighten it. If it’s going to attack, lie facedown, with your hands
held firmly behind your neck. Play dead until you’re sure the bear
is gone.
小題1:When you see a colorful cross made of rocks in the wilderness, you know    .
A.someone is bleedingB.someone is choking
C.someone is lostD.someone is attacked by a bear
小題2:If you are still choking after six tries, you should         .
A.keep a sense of humorB.call 911 and leave the line open
C.use your hand our clean cottonD.lie down with your hands behind your neck
小題3:Don’t tie around your bleeding leg tightly, or you could        .
A.stop bleedingB.reduce stress
C.lose your footD.cause breathlessness
小題4:The passage is mainly teaching us how to      .
A.survive the emergenciesB.a(chǎn)void a bear attack

There is no excuse for not doing your assignments(作業(yè)). If you can’t come to school, you should call your teacher or your classmate and ask about homework. It is your responsibility(責任)to find out what homework you have missed. It is not the teacher’s job to remind you of the missed assignments.
You must not be absent on a test day. If you are seriously ill, call and let the teacher know you will not be there for the test. If your teacher allows a make-up test(補考),you should take the test within one or two days after you return to class. Serious illness is the only reason for missing a test.
Be on time! It is impolite to be late. Also, it bothers other students. If you must come in late, be sure to do it quietly. Have your books and papers out of your bag before you come into the room. Then go to your seat and sit down quietly. In the USA, it is not necessary to knock before you enter the classroom. Most teachers will give you a low grade if you are often late.
In America, you should call your teacher by his or her last name instead of “ teacher”. Also you should use Mr, Miss, Ms or Mrs before the last name ( such as Mrs Smith or Mr Jones). This is polite. The teacher will tell you the title that he or she likes. It is impolite in the USA to eat, drink or chew gum during class. Don’t do these until the break. Also, removing your shoes in the classroom is not polite.

Children are our future, and it’s up to us to arm them with the tools to succeed. Sadly, today’s children are being armed with more dangerous tools like weapons (武器), drugs and gangs. Once a relatively peaceful environment, many schoolyards of today are becoming unsafe for both students and teachers.
Home schools are available to give you choices. Home schooling provides top-quality education, flexibility, and freedom to create your own schedule. At Heritage Home School we believe the choice should be yours. Thanks in part to modern technology, home schooling information is becoming readily available across our nation. A recent study by the ITBS (Iowa Tests of Basic Skills) and TAP (Tests of Achievement and Proficiency) shows us that students of home schools do particularly well when compared with the nationwide average. In every subject at every grade level, students of home schooling scored obviously higher than those in public and private schools.
If you’re new to home schooling, you may be asking yourself, “Will home schools really work for my children?”
Fact: A nationwide study using a random(任意)selection of 1,516 families found students of home schooling to be scoring, on average, at or above the 80th percentile in all areas on standardized achievement test.
Note: The national average on standardized achievement tests is the 50th percentile. Collectively, the staff at Heritage Home School brings 65 years of experience in home schooling curriculum. We’ve placed students in the top 2 % of the nation in math and many are successfully moving on to college.
One study found that of the home schooled adults, 0% were unemployed, 0% were on welfare and 94% said home education prepared them to be independent persons. For more home schooling information, call us today toll free at(877)532-7665.
小題1:We can learn from the first paragraph that ________.
