Business is the organized approach to providing customers with the goods and services they want. The word business also refers to an organization that provides these goods and services. Most businesses seek to make a profit(利润)—that is, they aim to achieve income that is more than the costs of operating the business.__1__ Commonly called nonprofits, these organizations are primarily nongovernmental service providers.__2__
Business management is a term used to describe the techniques of planning, direction, and control of the operations of a business.__3__ One is the establishment (制定)of broad basic policies with respect to production; sales; the purchase of equipment, materials and supplies; and accounting.__4__ The third relates to the establishment of st andards of work in all departments. Direction is concerned primarily with supervision(监管)and guidance by the management in authority. __5__
A.Control includes the use of records and reports to compare actual work with the set standards for work.
B.In this connection there is the difference between top management and operative management.
C.Examples of nonprofit businesses include such organizations as social service agencies and many hospitals.
D.However, some businesses only seek to earn enough to cover their operating costs.
E.Planning in business management has three main aspects.
F.In the theory of business management, organization has two main aspects.
G.The second aspect relates to the application of these policies by departments.
Public Speaking Training
·Get a coach
__1__，so get help. Since there are about a billion companies out there all ready to offer you public speaking training and courses, here are some things to look for when deciding the training that's right for you.
·Focus on positives
Any training you do to become more effective at public speaking should always focus on the positive aspects of what you already do well. Nothing can hurt confidence more than being told that you aren't doing well. __2__， so good public speaking training should develop those instead of telling you what you shouldn't do.
If you find a public speaking course that looks as though it's going to give you lots of dos and don'ts, walk away! Your brain is so full of what you're going to be talking about. __4__. As far as we're concerned, there are basically no hard and fast rules about public speaking. Your audience can be your friends.
·You are a special person not a clone
Most importantly, good public speaking training should treat you as a special one, with your own personal habits. __5__. Your training course should help you bring out your personality, not try to turn you into someone you're not.
A.You aren't like anybody else
B.You already do lots of things well
C.Turn your back on too many rules
D.Check the rules about dos and don'ts
E.Whatever the presentation, public speaking is tough
F.The one thing you don't want is for them to fall asleep
G.So trying to force a whole set of rules into it will just make things worse
To forgive is a virtue, but no one has ever said it is easy. When someone has deeply hurt you, it can be extremely difficult to let go of your hate. However, forgiveness is possible, and it can be surprisingly beneficial to your physical and mental health. People who forgive show less sadness, anger and stress and more hopefulness, according to a recent research.
__1__ Try the following steps：
Calm yourself. __2__ You can take a couple of breaths and think of something that gives you pleasure: a beautiful scene in nature, or someone you love.
Don't wait for an apology. Many times the person who hurt you does not intend to apologize. They may have wanted to hurt you or they just don't see things the same way. __3__ Keep in mind that forgiveness does not necessarily mean becoming friends again with the person who upset you.
Take the control away from your offender(冒犯者). Rethinking about your hurt gives power to the person who caused you pain. Instead of focusing on your wounded feelings, learn to look for the love, beauty and kindness around you.
__4__ If you understand your offender, you may realize that he or she was acting out of unawareness, fear, and even love. You may want to write a letter to yourself from your offender's point of view.
Don't forget to forgive yourself. __5__ But it can rob you of your selfconfidence if you don't do it.
A.Why should you forgive?
B.How should you start to forgive?
C.Recognize the benefits of forgiveness.
D.Try to see things from your offender's angle.
E.For some people, forgiving themselves is the biggest challenge.
F.To make your anger die away, try a simple stressmanagement technique.
G.If you wait for people to apologize, you could be waiting an awfully long time.
Until relatively recently, the vast majority of human being lived and died without ever seeing a city. The first city was probably founded no more than 5,500 years ago. __1__ In fact, nearly everyone lived on farms or in tiny rural (乡村的) villages. It was not until the 20th century that Great Britain became the first urban society in history—a society in which the majority of people live in cities and do not farm for a living.
Britain was only the beginning. __2__ The process of urbanization—the migration (迁徙) of people from the countryside to the city—was the result of modernization, which has rapidly transformed how people live and where they live.
In 1900, fewer than 40% of Americans lived in urban areas. Today, o ver 82% of Americans live in cities. Only about 2% live on farms. __3__
Large cities were impossible until agriculture became industrialized. Even in advanced agricultural societies, it took about ninetyfive people on farms to feed five people in cities.__4__ Until modern times, those living in cities were mainly the ruling elite (精英) and the servants, laborers and professionals who served them. Cities survived by taxing farmers and were limited in size by the amount of surplus food that the rural population produced and by the ability to move this surplus from farm to city.
Over the past two centuries, the Industrial Revolution has broken this balance between the city and the country.__5__ Today, instead of needing ninetyfive farmers to feed five city people, one American farmer is able to feed more than a hundred nonfarmers.
A.That kept cities very small.
B.The rest live in small towns.
C.The effects of urban living on people should be considered.
D.Soon many other industrial nations became urban societies.
E.But even 200 years ago, only a few people could live in cities.
F.Modernization drew people to the cities and made farmers more productive.
G.Modern cities have destroyed social relations and the health of human beings.
Using a Mobile Phone to Improve Mother and Child Health
People around the world are working to expand the uses for mobile technology in health care.
In the world, there are six billion mobile phone users in a population of seven billion people.
__1__ Africa has widespread adoption. Three or four years ago the penetration rates were 20 percent or 30 percent, and now they're getting upwards of 60 percent in some countries.
__2__ Earlier research has been to look at mobile technologies and HIV and AIDS. And so we have some great evidence on the effectiveness of mobiles.
During the first week of December, 2012, more than 4,000 people from 50 countries met for the fourth annual mHealth Summit. It brought together experts from what the organizers call the mHealth ecosystem.
In 2011 Secretary of State Hillary Clinton started a public/private partnership called the Mobile Alliance for Maternal Action, or MAMA. There are about 800 women a day and about three million babies a year die from pregnancy and childbirthrelated causes. __3__ The messages cover pregnancy and the first year of a baby's life. These health messages may also be sent to a pregnant woman's husband and motherinlaw. __4__
Messages can be text or voicemail. You can have a pregnant woman in Bangladesh registered into a system that provides messages that help her know what to do and when to do certain things.
Simple text messages can be important sources of information to people without Internet access. __5__ They have to be able to read through thousands of entries that come back to them on Google, for example, and then figure out what that information means to them. And that's not something that someone in a poor and uneducated kind of situation can do.
A.They have no access to the relevant information.
B.That way they too can understand what needs to be done.
C.Millions of messages about baby care are received every day.
D.A lot of work has been done to use mobile technology for health.
E.And the most rapidly growing markets are those in developing countries.
F.The program sends messages to women to educate them about their health.
G.Besides, online users may sometimes not understand all the information available.
Does a Dog Help a Teen with Low Selfesteem?
A dog is known as man's best friend for good reason. Loyal and affectionate, a dog companion can enrich its owner's life in many ways. __1__ Many teenagers suffer from periods of low selfesteem (自尊)as they try to navigate the wavy waters of adolescence and deal with all of its associated highs and lows.
A teenager who lacks selfesteem may feel isolated from his peers and unable to tell his parents about personal issues. The company of a dog can be a huge comfort and ease feelings of loneliness and awkwardness. A dog offers genuine unconditional love. __2__
All dogs need exercise，so taking his dog for a walk is the perfect opportunity for a teenager to get outdoors and benefit from fresh air and physical activity. Exercise allows people to take control of their bodies，which is often the first step toward regaining control of other aspects of their life，says mental health specialist Dr. Alan Cohen. __3__ Exercise releases chemicals called endorphins (内排肽)into the brain, which create positive responses in the body，including improved selfesteem.
Dogs can help teenagers be more sociable and make new friends, suggests HELPGUIDE. __4__ A dog is a great icebreaker，avoiding awkward social situations and putting the teenager at ease with people he meets. The more confident the teen becomes when out and about with his dog，the more his selfesteem will improve.
__5__ If a teenager is suffering from depression or developing dangerous habits such as alcohol and drug abuse，more extreme action may be required. In these cases，professional help should be sought and all treatment plans considered. Parents who suspect that their teen's low selfesteem is a sign of a far more serious problem should ask a suitably qualified health professional for advice.
A.In some cases, having a dog will not help with a teenager's low selfesteem.
B.It simply accepts its owner for who he is and doesn't judge, question or criticize.
C.Pets offer an unconditional love that can be very helpful to people with depression.
D.You don't have to worry about hurting your pet's feelings or getting advice you don't want.
E.In particular, someone with low selfesteem may find a pet dog to be extremely beneficial.
F.A teen may meet his peers while walking his dog in the park or taking part in a dog training class.
G.Many forms of exercise besides walking can be enjoyed with a dog, such as cycling, jogging and throwing a ball.
Trust has been considered as the basis of any relationship, including friendship. No relationship can last long with a lack of trust. Not many of your friends will have real faith in you as you would like to believe. __1__. Sometimes, it takes years, even a complete lifetime, to trust someone. However, how do we know if our friends have faith in us?
__2__. With whom will you share things that you don't want everyone to know? It would be with a close friend, whom you trust as much as you trust yourself. While a few of your friends may be fiercely protective of their privacy and may not tell their secrets to anyone, those who do, surely find you trustworthy and reliable.
Whom do you look up to for advice when you need it the most? It has to be either your parents or your friends. __3__. This is a shining example of trust. You only seek advice from people you hold in high regard and find dependable. The friends who trust you will never forget to include you in the important decisions of their life.
Arguments and heated discussions are a part of every relationship, and this is also true for friendship. __4__. While some people find it difficult to forgive and forget, your friends will never have problems moving on. It is because they trust you and believe that you will never cause any pain to them on purpose.
There are times in life when you find yourself a lonely soldier. __5__. Your friends will never let you down and will strongly stand for you when you need encouragement. You can determine that they trust you and believe in your beliefs, if they side with you when you need them the most.

F.If your friends share their secrets, there's a good possibility that they have much faith in you
G.However, people who are fortunate to have been blessed with true friends are never alone in any battle
Possessing a car gives one a greater degree of freedom. With the building of good fast motorways, long distances can be covered rapidly and pleasantly. __1__ You will no longer be forced to rely on public transport or work locally. You can choose from a greater variety of jobs and probably change your work more frequently as you are not limited to a small area.
Although you can afford to buy it now, you have to consider the future. __2__ However large the first sum you have to pay, you have to spend more in running the machine—the various taxes, the fuel, and of course the repairs. The last is especially endless. Any single repair may cost you thousands.
__3__ As more and more cars are produced and used, an even larger amount of poisonous gas is being sent out. Some of the contents of this gas, such as lead, can cause actual harm to th e health of people. Many of the minor illness of modern industrial society, such as headaches, tiredness, and stomachaches may just arise from the gas.
__4__ It has been said that when a man is sitting behind the wheel, his car becomes the display of his personality. People who are normally quiet and pleasant may become unrecognizable when they are behind the wheel. They are illmannered, aggressive and selfish. All their hidden character seems to be brought to the surface by the act of driving.

Examinations are almost always stressful. Students rarely know exactly what to expect on the test, and those who suffer from exam fear or exam anxiety can see their grades suffer as a result of this stress. For some students，exam fear causes them to “ seize up” and forget what they have studied.
__2__ Good study habits and learning how to relax can help students overcome exam fear.
__3__ According to Penn S tate University and Kids Health，proper study habits and preparation are the keys to cutting out exam fear. Avoid lastminute “cramming” for exams and actively listen while in class.
Focus on positive thoughts, relax the night before your test and reward yourself after the test is over. Often, people who suffer from exam anxiety cannot shut out negative though ts or emotions about the test, and this can contribute to feeling more anxiety than normal. __4__
Keep your mind and body healthy by getting enough sleep, eating well and exercising. Healthier people who are wellrested often do better on exams.
__5__ Exam fear is norma l. When that anxiety severely interferes (干扰)with your ability to take the test, however, outside help might be needed. Ask your teachers and family for support and help.
A.How To Succeed in An Exam
B.How To Overcome Exam Fear
C.Develop good study habits.
D.Understand that you are not alone and ask for help if necessary.
E.Remind yourself that it's just one test and that you can get through it.

Your teen is falling asleep in class
Teens have a busy morning schedule as they need to wake up and get moving very early in order to catch a bus and get to school by the required time. This means teens need to get their rest the night before or they will be too tired to learn anything at school. __1__
When a teen falls asleep in class, two things happen: he/she misses what is being taught and he/she loses the respect of the teacher. He/She may also receive a consequence from the school, depending on the classroom discipline policy. __2__
To prevent your teen from being sleepy in class, try these three tips：
*Set a time for “lights out” on school nights. This is never be any later than 10 p. m. and preferably 9 p.m. __3__ Soft music can be on and used to help calm your teen.
*Help your teen develop a nighttime routine that involves activities that slow them down for the end of the day. __4__ Turning off the computer and disconnecting f rom friends and the excitement of the day an hour before bedtime will also help your teen relax.
*__5__ This will reinforce(增强)what it feels like to be rested and capable of accomplishing what he/she wants.
A.What's worse, they may even fall asleep in class.
B.Taking a bath and reading are two activities that work well.
C.Set a good example and show him/her your love for learning.
D.Point out the positives after your teen has had a good night's rest.
E.“Lights out” means the computer, television lights and cell phone should be off.
F.All of these things affect your teen's academic success and can be avoided.[来源:学科网]
G.While your teen keeps his/her goals in line with your expectations, he/she may have his/her own goals.
It makes no difference what you read or study if you can't remember it. You just waste your valuable time. __1__ One dependable aid that does help you remember what you study is to have a specific purpose or reason for reading.
Why does a clerk in a store go away when your reply to her offer to help is, “No, thank you.I'm just looking.” Both you and she know that if you aren't sure what you want, you are not likely to find it.But suppose you say instead, “Yes, thank you.I want a pair of sun glasses.” She says, “Right this way, please”
__2__ If you choose a book, “just looking” for nothing in particular, you are likely to get just that—nothing.But if you do know what you want, you are almost sure to get it.Your reasons will vary; they will include reading or studying “to find out more about”， “to understand the reasons for” and “to find out how”.
__3__ Before you start to study, you say to yourself something like this, “I want to know why Stephen Vincent Benet happened to write about America”.Because you know why you are reading or studying, you relate the information to your purpose and remember it better.
__4__ At least two important processes go on at the same time.As you read, you take in ideas rapidly and accurately. But at the same time you express your own ideas to yourself as you react to what you read. You have a kind of mental conversation with the author.
This additional process of thinking about what you read includes evaluating it, relating it to what you already know, and using it for your own purposes. __5__ One part of critical reading, as you have discovered, is distinguishing between facts and opinions.Facts can be checked by evidence; opinions are one's own personal reactions.Another part of critical reading is judging sources.Still another part is drawing accurate inferences.
A.Maybe you have already discovered some clever ways to keep yourself from forgetting.
B.It is important for students to have a positive attitude to their study.
C.You remember better when you know what you' re reading.
D.In other words, a good reader is a critical reader.
E.It's quite the same with your studying.
F.Reading is not one single activity.
G.This is the way it works.
I always reflect on what happened in my life. I think this is important—to appreciate our wins, losses, new passions, insights, etc. __1__ Here are some tips for you on reflection.
1.Focus on the process and not the outcome.
This thought was beautifully summed up by Srikumar Rao. He explains how we fail because we focus our energies on the outcome rather than the process itself. When a child learns to walk, she never focuses on the outcome but on the process.
2.Failure is a lead not a stop sign.
When you hit a wall and things don't turn up the way they are intended, no one is saying to you, “This is where you stop because you failed”. If you do, you are reading the wrong information. Failure tells us, “__2__ Try another method.”
3.Happiness is not the destination but the journey.
We think that happiness is a result that comes after having acquired or achieved something we don't have. This is not quite right. __3__ It's about s tepping back and enjoying the ride rather than expecting it at your destination point.
4.Wisdom comes from the balance between your knowledge and your heart.
Let your heart talk more; it wiser than you think. You can be as knowledgeable and clever as one can be. __4__ Wisdom is really having reached a stage where you balance all your knowledge with your heart.
5.Gratitude is the energydrink of the soul.
Say thank you to the universe every morning. Appreciation can lift your soul from anxiety which weighs you down. Try it out. __5__ It will help you appreciate life with more depth and perspective.
A.Failure is the mother of success.
B.Happiness is when we accept and enjoy everything as it is.
C.This method and the intended result do not match.
D.Be thankful to at least one thing in your day.
E.Not reflecting on our lives and experiences is a wasted chance for growth.
F.Happiness means achieving your goals and getting what you want.
G.But if your mind doesn't go with your heart, you are losing energy in internal conflicts.
Kids in the Kitchen
Some experts serve up some of the factors that make cooking with kids a pleasure rather than a struggle.

__2__ When kids help, you'll need extra time to teach them some skills.When you're in a hurry, give your kids tasks that don't require much guidance.As they get older and develop more skills, they will become wonderful helpers and even save your time!
Go for Variety
Our experts agree that children can enjoy more than the usual “kid food”， such as chicken nuggets and pizza. __3__ Sandra K.Nissenberg suggests exploring the produce passage in the supermarket and talking about the unusual fruits and vegetables you find.

Dr.Laura Colker reminds parents that preschoolers are eager to deal with grownup tasks.They actually “enjoy the cleanup and tablesetting activities”， she says. __4__
They may also enjoy setting the table and counting the spoons.

1.Make a list. Think of what you need from your head to your toes. __2__ When you've done this once, it'll be easier next time.
2.Consider buying smallsize samples of shampoo, toothpaste, and other items at your local drugstore. You can reuse the plastic containers next time you go away too.
3.Choosing which clothes to bring is probably the hardest packing decision to make.

If so, fine. __3__ Don't try to fool yourself. You are the one who will be left holding the bag.
4.Weather is an important factor in your packing. If it's cold, you could wear a jacket, a sweater, a regular shirt, and a Tshirt. Putting them on will keep you warm. __4__ Remember how much easier it will be to carry your bag! As for shoes, you may want to call ahead to see if dress shoes are necessary.

Write it out
You can also check a math problem by writing everything out on paper. __2__ Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.
Make sure your answers work by doing the opposite procedure of what your problem calls for, including the answer you got the first time around. In other words, you would use the opposite of this addition problem—subtraction (减法)—to determine whether or not your answer is the correct one.
You may find that a variable isn't good enough or have a problem where you have to solve for a variable (变量). __4__ This is the only real way to assure yourself that the answer you've found is correct.
Check for a reasonable answer[来源:Zxxk.Com]
__5__ For example, if you get an answer in the millions and you know it should be in the thousands, you've likely misplaced a point. Go back through the work on your paper to make sure all of your formulas and calculations are correct. If everything looks okay, do the problem again and compare the result of the second try to what you've got on the first try.
A.Do the opposite
B.Correct the answers
C.Plug the variable in the equation (方程) to check it out.

People say going to college will change your life and that everyone should have the chance to challenge themselves with a college experience.But my parents never had that opportunity.
All during high school I wondered if I would go to college and if I would have what my parents never had.I would think about my future, about college and what I wanted to do when I grew up.But then there were thoughts of not going, of believing what others said about college and thinking I had no chance to go.
As I reached the end of junior year, I knew I needed to make a decision.__2__ I felt somewhat sad.One day I was having a conversation with my volleyball coach.We talk all the time.but that day college was the topic. __3__ However, what she told me was encouraging.Thoughts flew through my mind about what I wanted to become and what colleges I might be interested in.She mentioned things I had no idea about, like scholarships and financial aid that can help you pay for college.All this information inspired me to continue.She told me about her college experience and all the fun times she'd had.__4__
This conversation changed me. __5__ If I hadn't talked with her.I wouldn't know where I would be today.I now want to make something of myself.I want to become somebody that I wasn't before.I want to go to college.
