"Happiness isn't just feeling good.It's good for you and for society.Happy people are more successful, have better relationships, are healthier and live longer," said Ed Diener, a professor of psychology at the University of Illinois.

Beyond your genes

Sonja Lyubomirsky, a professor of psychology at University of California Riverside, analyzed studies on identical twins and concluded that happiness is 50 percent genetic, 40 percent intentional and 10 percent circumstantial.

"Your circumstances—where you live, your health, your work, your marriage—can be tough to change.But most people are surprised that circumstances (环境) don't account for as much of their happiness as they think," she said.

Life circumstances don't result in continuous happiness, she says, because we adapt.That new car, promotion or house feels great at first.Then we get used to it.Keeping that good feeling requires something else: control of how you act and think.

Happiness defined

       To gain happiness, you need to understand what happiness is.

Martin Seligman, a psychology professor at the University of Pennsylvania, says happiness is the pursuit of engaging and meaningful activities.

By "engaging", he means when we get so absorbed in what we are doing that we lose track of time. "Meaningful" would be using what you are best at to serve others or to participate in a cause that's

bigger than yourself.

"Your purpose doesn't have to be giant," says psychologist Dan Baker."If you're 17, your.purpose can be getting into the college of your choice.When you're a parent, it can be getting your kids off to school safely and prepared for each day."

External factors

From 1981 to 2007, the World Values Survey took polls (民意测验) all over the world and measured what it considers happiness and overall life satisfaction.Of the 52 countries that completed the surveys over the 17-year period, happiness increase in 45.

According to the survey analysis, economic growth helped promote happiness for some, while Democratization(民主化)and rising social tolerance contributed even more

Democracy provides more choice, which promotes happiness.Support for sex equality and tolerance of people who are different from oneself are also strongly linked.This is not just because tolerant people are happier, but because living in a tolerant society strengthens everyone's freedom.

68.Professor Sonja Lyubomirsky found that ____.

       A.we get continuous happiness as a result of life circumstance

       B.happiness is more genetic than circumstantial

       C.new car, promotion or house can make people happy for a Song time

       B.to gain happiness, we needn't understand the meaning of happiness

       C.happiness, is the pursuit of engaging and meaningful activities

       D.it's no point in paying attention to engaging and meaningful activities.

70.The World Values Survey suggests people are more likely to promote happiness if____.

       A.they can choose to be those who are different from others

       B.they get much money or raise social states

In Britain and other countries, young people sometimes take a "gap year", a year off between high school and college.This idea never gained a big following in America.Recent news reports have suggested that interest may be growing, though there are no official numbers.

Charles Deacon, Dean of Admissions at Georgetown University in Washington, D.C., estimates that in the first-year class of 1600 students, only about 25 decided to take a year off.He says this number hasn't changed much over the years.

Mr.Deacon says the most common reason for taking a "gap year" is to have a chance to travel, but he says international students may take a "gap year" to meet requirements at home for military (军事的)duty.

Some high school graduates see a year off as a chance to recover after twelve years of required education, but it can also give students a chance to explore their interests.Students hoping to be doctors, for example, could learn about the profession by volunteering in a hospital.

Many colleges and universities support gap-year projects by permitting students to delay their admission.Experts say students can grow emotionally and intellectually as they work at something they enjoy.

The Harvard admissions office has an essay on its Web site called "Time Out or Bum Out for the Next Generation".It praises the idea of taking time off to step back.think and enjoy gaining life experiences outside the pressure of studies.It also notes that students are sometimes admitted to Harvard or other colleges partly because they did something unusual with that time.

Of course, a " gap year" is not for everyone.Students might miss their friends who go on directly to college, and parents might worry that their children will decide not to go to college once they take time off.Another concern is money.A year off, away from home, can be costly.

Holly Bull's job is to specialize in helping students plan their "gap year".She notes that several books have been written about this subject.She says these books along with media attention and the availability of information on the Internet have increased interest in the idea of a year off, and she points out that many gap-year programs cost far less than a year of college.

We now think of chocolate as sweet, but once it was bitter.We think of it as a candy, but once it was a medicine.Today, chocolate can be a hot drink, a frozen dessert, or just a snack.Sometimes it's an ingredient(配料) in the main course of a meal.Mexicans make a hot chocolate sauce called mole and pour it over chicken.The Mexicans also eat chocolate with spices(香料) like chili peppers.

Chocolate is a product of the tropical cacao tree.The beans taste so bitter that even the monkeys say "Ugh!" and run away.Workers must first dry and then roast the beans.This removes the bitter taste.

The word "chocolate" comes from a Mayan word.The Mayas were an ancient people who once lived in Mexico.They valued the cacao tree.Some used the beans for money, while others crushed them to make a drink.

When the Spaniards came to Mexico in the sixteenth century, they started drinking cacao too. Because the drink was strong and bitter, they thought it was a medicine.No one had the idea of adding sugar.The Spaniards took some beans back to Europe and opened cafes.Wealthy people drank cacao and said it was good for the digestion.

In the 1800s, the owner of a chocolate factory in England discovered that sugar removed the bitter taste of cacao.It quickly became a cheap and popular drink.Soon afterwards, a factory made the first solid block of sweetened chocolate.Later on, another factory mixed milk and chocolate together. People liked the taste of milk chocolate even better.

Besides the chocolate candy bar, one of the most popular American snacks is the chocolate chip cookie.Favorite desserts are chocolate cream pie and, of course, an ice cream sundae with hot fudge sauce.

You have waited 45 minutes for the valuable 10 minutes' break between classes.But when the bell for the next class rings, you can't 36 how quickly time has passed.

If you are familiar with this__37_,you'll know how time flies when you are having fun.And how time 38 when you are bored.Now scientists have 39 a reason why this is the case.

Scans have shown that patterns of activity in the brain_ 40 according to how we focus on a task.When we are 41 .we concentrate more on how time is passingAnd this makes our brains_42_the clock is ticking more slowly.

In an experiment 43 by a French laboratory, 12 volunteers watched an image 44 researchers monitored their brain activity.The volunteers were told to 45 concentrate on how long an image appeared for, then 46 _the color of the image, and thirdly, study both duration(持续的时间) and color.The results showed that 47 was more active when the volunteers paid 48 subjects.

It is thought that if the brain is  49  focusing on many aspects of a task, it has to 50 its resources, and pays less attention to the clock51 ,time passes without us really 52 it, and seems to go quickly.If the brain is not so active, it concentrates its__53___energies on monitoring the passing of time.__54_.time seems to drag.
