Deborah Cohen is a senior natural scientist at the Rand Corp and the author of the book A Big Fat Crisis: The Hidden Forces Behind the Obesity Epidemic and How We Can End It. According to the book, there are lots of misunderstandings of obesity.
1. If you’re obese, blame your genes.
Obesity rates have increased. Yet, between 1980 and 2000, the number of Americans who are obese has doubled—too quickly for genetic factors to be responsible.
At restaurants, a dollar puts more calories on our plates than ever before, because restaurant meals usually have more calories than what we prepare at home, so people who eat out more frequently have higher rates of obesity than those who eat out less.
2. If you’re obese, you lack self-control.
Research shows that if we are faced with too much information, we have a tendency to make poor dietary choices. Our world has become so rich in temptation that we can be led to consume too much in ways we can’t understand. Even the most vigilant(警觉的) people may not be up to the task of controlling themselves.
3. Lack of access to fresh fruits and vegetables is responsible for obesity.
Although the US Department of Agriculture estimates that fewer than 5 percent of Americans live in the “food deserts”, about 65 percent of the nation’s population is overweight or obese. For most of us, obesity is not related to access to more fresh fruits and vegetables, but to the choices we make in supermarkets.
4. The problem is not that we eat too much, but that we don’t exercise.
Michelle Obama’s “Let’s Move” campaign is based on the idea that if kids exercise more, childhood obesity rates will decrease. But there was no significant decrease in physical activity levels as obesity rates climbed in the 1980s and 1990s. In fact, although a drop in work-related physical activity may account for up to 100 fewer calories burned, leisure physical activity appears to have increased. The problem is that we eat too much.

Both of Jessica’s parents were lawyers and expected her to follow suit. So she went to law school, got a job at a great firm in Washington, DC, and worked as a lawyer for a decade. But her heart was never in it. “I had a big salary but no personal satisfaction,” she says.
Jessica found pleasure in the same thing that had brought her joy since joining the church choir at the age of 12. “Singing always felt like communicating something real at a spiritual and emotional level,” says Jessica. Yet she never considered it a career option. “That seemed like something people did in fairy tales, and I would never let my parents down,” she says.
It was her mom’s diagnosis of brain cancer in 2009 that made Jessica realize she had to write her own happy-ever-after. “Work was busy and my mother was ailing. So I was flying back and forth from Washington, DC to Houston to see her,” Jessica says. “I finally said, ‘Enough!’ and quit.” While caring for her mom, Jessica made a plan. She would spend her savings and study music for a year, and then open a part-time law practice so she could pursue her passion. Before her mother passed away two years later, she encouraged Jessica to follow her dream. Her song Live This Life was inspired by her mom, and her dad came to watch her perform at clubs.
In 2012, Jessica moved to Nashville to try singing and songwriting. A decade of presenting cases in court gave her the confidence to sing for a crowd. “At 20, I would have been too shy to perform,” says Jessica.
“Doing music is so free,” Jessica says. “There’s no pressure to be a star. Success, to me, isn’t a dollar amount or a record deal; it’s doing what I love.”
Which of the following is TRUE?

A．Jessica wasn’t satisfied with the pay she got as a lawyer.

C．Jessica didn’t really like working as a lawyer.

D．Jessica was grateful for her parents’ arrangement for her.

Never Talk to Strangers?
“Never talk to strangers.” Many children are taught this simple rule as a precaution against abduction(诱拐). In June, 2005, an 11-year-old boy was lost in the Utah wilderness for four days. During that time, he stayed on the path. He saw people searching for him but deliberately hid from them, afraid someone might “steal” him. Eventually, the unfortunate game of hide-and-seek ended and he was found. According to the Canada Safety Council, this alarming incident shows how unwise it is to instill(灌输) a fear of strangers in children. The “stranger danger” message can prevent children from developing the social skills and judgment needed to deal effectively with real-life situations. In a difficult situation, a stranger could be their lifeline to safety.
To have a child go missing is a parent’s worst nightmare. The threat of abduction by a stranger is minimal when compared with other possible reasons for a disappearance. In 2004, there were 67,266 missing-children cases in Canada. Only 31 involved abduction; in most of those cases the abductor was a relative, friend, or person known to the family. There were 671 cases of children wandering off, and 332 cases of abductions by a parent. Almost 80 percent of all cases were runaways. These statistics cast doubt on the idea that children should never talk to strangers. Wandering off is more common—but a lost children may have to call upon a stranger for help, and must develop the ability to judge what kind of people to approach. The “never talk to strangers” rule does not protect children in the situations they are most likely to face. On top of this, it can be confusing. Adults do not model the behaviour; they often talk to strangers. A child may not know how to tell who is a stranger, and who is not.
For young children, nothing replaces close supervision(监管). Pre-schoolers do not understand risk and tend to act without thinking. Children need to develop habits and sttitudes that will protect them from the real threats and dangers they may face. The Canada Safety Council encourages parents to give their children age-appropriate positive messages about safety, bearing in mind how youngsters may understand their world.
Which of the following statements is NOT true about the 11-year-old boy?

A．He practiced the “never talk to strangers” rule.

B．He hid from the rescuers to avoid possible abduction.

C．He eventually showed up when his hide-and-seek game ended.

D．He stayed where he was, expecting the coming of familiar people.

Among the possible reasons for the missing-children cases in Canada, which one is the most frequent?

A．Being abducted by a parent.	B．Wandering off.
C．Being abducted by strangers.	D．Running away.

The “never talk to strangers” rule is confusing to children because ___.

A．a friendly and attractive person may be dangerous

B．adults do not act upon the rule and strangers are hard to tell

C．the rule does not protect children in the situation of abducting

D．a lost child may have difficulty in communicating with a stranger

Which would the author agree with about the “never talk to strangers” rule?

A．It is not well recognized by parents.

B．It is not effective in keeping kids safe.

C．It is easy enough for children to follow.

D．It is practical as a safety tip in daily life.

It is bad to have food stuck between your teeth for long periods of time. This is because food attracts germs(细菌), germs produce acid, and acid hurts your teeth and gums. Flossing(使用牙线) helps to remove the food that gets stuck between your teeth. This explains why flossing helps to keep your mouth healthy, but some doctors say that flossing can be also good for your heart.
It may seem strange that something your do for your teeth can have any effect on your heart. Doctors have come up with a few ideas about how flossing works to keep your heart healthy. One idea is that the germs that hurt your teeth can leave the mouth and travel into your blood. Germs that get into the blood can then attack your heart. Another idea is based on the fact that when there are too many germs in your mouth, the body tries to fight against these germs. For some reason, the way the body fight these mouth germs may end up weakening the heart over time.
Not every doctor agrees about these ideas. Some doctors think that the link between good flossing habits and good heart health is only a coincidence. The incidence(发生率) of two or more events is completely random, as they do not admit of any reliable cause and effect relationship between them. For example, every time I wash my car, it rains. This does not mean that when I wash my car, I somehow change the weather. This is only a coincidence. Similarly, some doctors think that people who have bad flossing habits just happen to also have heart problems, and people who have good flossing habits just happen to have healthy hearts.
The theory that flossing your teeth helps to keep your heart healthy might not be true. But every doctor agrees that flossing is a great way to keep your teeth healthy. So even if flossing does not help your heart, it is sure to help your teeth. This is enough of a reason for everyone to floss their teeth every day.

Wild
I was 16 when my father finally decided he would send me to wilderness camp for several months. He had threatened to do it many times before, but my mother had always managed to prevent him from doing so. This time he insisted on doing it.
The latest incident was the last straw. Impulsively(冲动地), I hade pushed Mr. Ford, my math teacher, down a flight of steps at school. He broke his arm in two places. Anyway, he had agreed not to accuse me as a favour to my dad, who was in the middle of a tight race for sheriff(执法官) in our town. But my reckless behaviour had my dad’s closest advisor talking.
“John, he’s your son and he’s a kid, but he is dragging you down,” I heard Jake Hutch tell my dad through his closed office door the night after I pushed Mr. Ford. “If you can’t make your son obey the rules, how can you make the law obeyed in this town?”
So, off to Pisgah National Forest I went. I imagined hours of untold abuse at the hands of some strong sergeants(警官). I was determined no to be broken. I was who I was.
Nearly every day for six months, a small group of other troubled teens and I carried our 30-pound backpacks on a difficult journey covering about 10 miles. We hiked in a rough wilderness that seemed untouched by civilization.
Our sergeants were firm but kind, not frightening as I had imagined. We learned how to make a fire without matches and create a shelter with branches and grass. We learned which plants were safe to eat out in the wild. I felt myself change. I was calm and often reflective. My old, impulsive self was gone.
One morning, six months later, my dad came to pick me up. I ran to hug him and saw relief and love in his eyes.
“So what’s it like being sheriff?” I asked on the ride home.
“I lost the race, Danny,” he said.
“I’m sorry, Dad.” I knew my behaviour probably had a lot to do with hid defeat.
Dad squeezed my shoulder and brought me close. “As long as I don’t ever lose you, I’m okay.”
