New research suggests that cutting daily sitting time to less than three hours might extend your life by two years.
“Humans were designed to move. But modern lifestyles and office jobs rarely encourage us to walk around,” says Peter Katzmarzyk, an expert at the University of Louisiana.
“Sitting is common in our lives today. We sit while we’re driving, eating and watching TV. And many of us sit for many hours at work.” Katzmarzyk said.
“We can’t throw away physical activity. It’s extremely important. We have 60 years of researchers showing us that.” Katzmarzyk said.
Katzmarzyk and other researchers are trying to discover how sitting all day affext our lifespans（寿命）.
“This is a relatively new area of study…Studies that have assessed the relationship between sitting and death or television viewing and death have been very rare in the last four or five years,” said Katzmarzyk.
Katzmarzyk and his colleagues analyzed data from these studies, which involved almost 167,000 adults. Then they turned to a government-run survey of Americans to find out exactly how much time people spend sitting and watching.
Not only did the team find that U.S. citizens could live longer by sitting less, they found that cutting TV time to less than two hours a day could add an extra 1.4 years to their lives.
People who’ve spent half their waking lives sitting down might well ask, “Is it ever too late to make a change?”
“We would say ‘No. It’s never too late.’ Physical activity is good for you at every age.” Katzmarzyk said.
Katzmarzyk says studying this problem has inspired his team to make a few changes in their own lives. They recommend a few simple changes: frequently getting up from your desk, taking walks at lunch time, and instead of e-mailing colleagues, walking over to their offices and talking face-to-face——all activities that can be enjoyable as well as life-extending.

I find some of the ways in which Chinese parents show love for their children rather surprising. Obviously there are some pretty big differences between our behaviors and theirs in this respect. Most Chinese children seem to get whatever they want, from ice creams, sweets and toys to endless attention from the adults around them. Is this a sort of spoiling or love? I wonder.
Most westerners would think it is a sort of spoiling rather than love. We think love means educating your children and bringing them up to lead an independent life. That includes learning to accept the fact that he can't get everything he wants. As an adult, he will not always get the quite expensive car he hunts for; she will not always manage to acquire the beautiful dress she longs for. So we try to teach our children early to cope with the disappointment of not getting what they want.
I find too much such kind of love for the children can actually spoil them. To my surprise, it seems that the life of a Chinese child is rather hard. Without doubt, the child is the very center of a whole circle of adults, but on the other hand he or she is also expected to start studying according to adults' wishes. Many children of my son's age take piano lessons, painting classes and even English lessons. It looks as if Chinese adults think that just playing without learning anything is a waste of time. So in this respect our children appear spoiled, just because they are allowed to play. But without this sort of play how can western children develop such free and rich imaginations? In fact the connection between this imagination and the creativity is so important in the children’s future life.
In which way do most Chinese children seem to be spoiled?

A．They can be supported by their parents.

B．They can play whenever they want.

C．They need not behave themselves.

D．Their demands can always be satisfied.

In the author's opinion, the life of a Chinese child is .

A．rather hard

B．rather easy

C．independent

D．colorful

The author thinks Western children appear spoiled because .

A．they can manage time by themselves

B．they can have the freedom to play

C．they can take piano lessons

D．they may have expensive toys

The best title of the passage could be .

A．Chinese children's early education

B．How to develop kids' imagination

C．What is the real love for children

D．The imagination and creativity

Getting married can be one of the happiest moments in a person’s life. Throughout the world, weddings are very important events. Let’s look at some interesting wedding customs from different countries.
For African Americans, it is tradition for the married couple to jump over a broom covered with flowers. This represents the beginning of family life. It is interesting to note that African slaves who were brought to the USA started this tradition. African American couples were not allowed to have a legal marriage, so instead they had a ceremony where the bride and groom jumped over a broom “into marriage”.
Making jokes about the bride and groom is a wedding tradition in both France and Germany. In France, this includes making loud noises with pots; in Germany, wedding guests break dishes. Weddings in Germany often last for three days. On Thursday, there is a simple ceremony at a government office noting the official marriage of the couple. Then the couple will have a dinner with family and close friends. On Friday, there is a party. This is when guests break dishes to represent the start of a new life. Then on Sunday, there is a ceremony in a church.
In Greece and Italy, people eat special kinds of sweets at the wedding. Both Greece and Italy also have their own special wedding dances, which all of the guests enjoy.
In Russia, couples tie a doll to their wedding car if they want to have a daughter, or a toy bear if they want to have a son.
In England, it is tradition for the little girls to throw flowers on the ground on the way to the wedding ceremony. The bride and groom walk on these flowers. This represents the hope that the couples will follow the path that leads to a happy life.

Each time I see a balloon, my mind flies back to a memory of when I was a six-year-old girl. It was a rainy Sunday and my father had recently died. I asked my mom if Dad had gone to heaven. “Yes, honey. Of course.” she said.
“Can we write him a letter?”
She paused, the longest pause of my short life, and answered, “Yes.”
My heart jumped. “How? Does the mailman go there?” I asked.
“No, but I have an idea.” Mom drove to a party store and returned with a red balloon. I asked her what it was for.
“Just wait, honey. You’ll see.” Mom told me to write my letter. Eagerly, I got my favorite pen, and poured out my six-year-old heart in the form of blue ink. I wrote about my day, what I learned at school, how Mom was doing, and even about what happened in a story I had read. For a few minutes it was as if Dad were still alive. I gave the letter to Mom. She read it over, and a smile crossed her face.
She made a hole in the corner of the letter where she looped (缠绕) the balloon string. We went outside and she gave me the balloon. It was still raining.
“Okay, on the count of three, let go. One, two, three.”
The balloon, carrying my letter, darted upward against the rain. We watched until it was swallowed by the mass of clouds.
Later I realized, like the balloon, that Dad had never let his sickness get him down. He was strong. No matter what he suffered, he’d persevere, dart up, and finally transcend this cold world and his sick body. He rose into sky and became something beautiful. I watched until the balloon disappeared into the gray and white and I prayed that his strength was hereditary. I prayed to be a balloon.
