At a primary school Manning， Carolina， second-grade teacher David Chadwell believed that segregating(隔离) elementary-age boys and girls produces immediate academic improvement—in both genders. “Although this is a tendency， we can teach boys and girls based on what we now know.”

“They see differently. Literally，” he begins. Male and female eyes are not organized in the same way， he explains. The composition of the male eye makes it attuned(协调) to motion and direction. “Boys interpret the world as objects moving through space，” he says. “The teacher should move around the room constantly and be that object.”

The male eye is also drawn to cooler colors like silver， blue， black， grey， and brown. It’s no accident boys tend to create pictures of moving objects like spaceships， cars， and trucks in dark colors instead of drawing the happy colorful family， like girls in their class.

The female eye， on the other hand， is drawn to textures and colors. It’s also oriented toward warmer colors—reds， yellows， oranges—and visuals with more details， like faces. To engage girls， Chadwell says， the teacher doesn’t need to move as much， if at all. Girls work well in circles， facing each other. Using descriptive phrases and lots of color in overhead presentations or on the chalkboard gets their attention.

Boys and girls also hear differently. “When someone speaks in a loud tone， girls interpret it as yelling，” Chadwell says. “They think you’re mad and can shut down.” Girls have a more finely tuned aural structure； they can hear higher frequencies than boys and are more sensitive to sounds. He advises girls’ teachers to watch the tone of their voices. Boys’ teachers should sound matter of fact， even excited.

A boy’s autonomic nervous system causes them to be more alert when they’re standing， moving， and the room temperature is around 69 degrees. Stress in boys， he says， tends to increase blood flow to their brains， a process that helps them stay focused. This won’t work for girls， who are more focused seated in a warmer room around 75 degrees. Girls also respond to stress differently. When they are exposed to threat and confrontation， blood goes to their guts(内脏)， leaving them feeling nervous or anxious.

“Boys will rise to a risk and tend to overestimate their abilities，” he says. “Teachers can help them by getting them to be more realistic about results. Girls at this age shy away from risk， which is exactly why lots of girls’ programs began in the private sector. Teachers can help them learn to take risks in an atmosphere where they feel confident about doing so.”

At age 61, identical twins Jeanne and Susan no longer look exactly alike. Susan smoked for many years and is an admitted sun worshipper, whose habits Jeanne does not share. A new study of twins suggests you can blame those coarse(粗糙的)wrinkles, brown or pink spots on too much time in the sun, smoking, and being overweight.

       Because twins share genes, but may have different exposures to environmental factors， studying twins allows an “opportunity to control for genetic susceptibility(易受影响性),” Dr. Elma D. Baron, at Case Western Reserve School of Medicine in Cleveland, Ohio, and his colleagues explain in the latest issue of Archives of Dermatology.

       Their analysis of environmental skin-damaging factors in 65 pairs of twins hints that skin aging is related more to environment and lifestyle than genetic factors.

       But when it comes to skin cancer, the researchers say their findings support previous reports that both environment and genes affect skin cancer risk.

       Baron’s team examined facial skin of 130 twins, 18 to 77 years old, who lived mostly in the northem Midwest and Eastern regions of the US, who were attending the Twins Days Festival in Ohio in August 2002. At this time, each of the twins also separately reported how their skin burned or tanned(晒黑)without sunscreen, their weight, and their history of skin cancer, smoking, and alcohol drinking. The study group consisted of 52 fraternal(异卵双生)and 10 identical twin pairs, plus 3 pairs who were unsure of their twin status.

       From these data, the researchers noted strong ties, outside of twin status, between smoking, older age, and being overweight, and having facial skin with evidence of environmental damage. By contrast, sunscreen use and drinking alcohol appeared related to less skin damage.

       Baron and his colleagues say the current findings, which highlight ties between facial aging and potentially avoidable environmental factors—such as smoking, being overweight, and unprotected overexposure to the sun’s damaging rays—may help motivate people to minimize these risky behaviors.

Which of the following is true according to the passage?

       A．Jeanne and Susan share all the habits including smoking.

       B．Skin aging is related more to environment and lifestyle than genetic factors.

       C．Only identical twins can take part in the research.

       D．Sunscreen use cannot help people have less skin damage.

Why did Baron’s team do the research on twins?

       A．Twins are more likely to suffer from skin cancer.

       B．It may guarantee the research is not influenced by genetic factors.

       C．It gives others an opportunity to control twins’ genes.

       D．It helps find twins are exposed to different environments.

What can you infer from the last paragraph?

       A．This research makes people aware of dangerous lifestyles.

       B．The environmental factors are unavoidable.

       C．Being exposed to the sun is absolutely damaging.

       D．There is little relationship between skin aging and environment.

The passage is mainly concerned with      .

       A．skin cancer and environment

       B．identical twins research

       C．aging skin and environmental factors

       D．genes and lifestyles

Risk of death is 3.5 to 5 times greater for obese (肥胖的) smokers than it is for people who have never smoked and are at a normal weight, according to a study published in the November, 2006 issue of the American Journal of Preventive Medicine.

The study, which began with a self-administered questionnaire taken between 1983 and 1989, asked more than 80,000 radiologic technologists aged 22 to 92 questions about age, height, weight and smoking behavior.

    BMI (body mass index) was calculated, with a BMI of 30 to 34.9 being considered obese, and 35 and over being very obese. Smoking behavior was analyzed by looking at a person's tobacco consumption level, number of years smoked, and current smoking status. Researchers then followed participants through December of 2002, noting the number of deaths that occurred.

    The study involved researchers from the National Cancer Institute, the University of Minnesota and the American Registry of Radiolegic Technologists.

    Key Findings:

    20 percent of obese adults in the United States smoke.

    Obese smokers face a greater risk of death from cancer and circulatory disease.

    Current smoking is a greater risk factor for death by cancer than obesity is, generally speaking.

    The higher a person's pack-years (number of packs smoked per day times the number of years smoked) are, the greater the risk of death.www.zxxk.com

    Men and women of all ages faced an elevated risk of death due to circulatory disease as BMI increased. And for those who were both obese and currently smoking, risk of circulatory disease increased 6 to 11 times under the age of 65, as compared to their never-smoking, normal weight counterparts.

    While it's not surprising that obesity coupled with smoking is a recipe for trouble, it is important to highlight this growing health concern in America today.
