D
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.
67．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.
68．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.
69．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.
70．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

Diana Jacobs thought her family had a workable plan to pay for college for her 21-year-old twin sons: a combination of savings, income, scholarships, and a modest amount of borrowing. Then her husband lost his job, and the plan fell apart.
“I have two kids in college, and I want to say ‘come home,’ but at the same time I want to provide them with a good education,” says Jacobs.
The Jacobs family did work out a solution: They asked and received more aid form the schools, and each son increased his borrowing to the maximum amount through the federal loan (贷款) program. They will each graduate with $20,000 of debt, but at least they will be able to finish school.
With unemployment rising, financial aid administrators expect to hear more families like the Jacobs. More students are applying for aid, and more families expect to need student loans. College administrators are concerned that they will not have enough aid money to go around.
At the same time, tuition（学费）continues to rise. A report from the National Center for Public Policy and Higher Education found that college tuition and fees increased 439% from 1982 to 2007, while average family income rose just 147%. Student borrowing has more than doubled in the last decade,
“If we go on this way for another 25years, we won’t have an affordable system of higher education,” says Patrick M. Callan, president of the center. “The middle class families have been financing it through debt. They will send kids to college whatever it takes, even if that means a huge amount of debt.”
Financial aid administrators have been having a hard time as many companies decide that student loans are not profitable enough and have stopped making them. The good news, however, is that federal loans account for about three quarters of student borrowing, and the government says that money will flow uninterrupted.

For years I wanted a flower garden．But then we had Matthew．And Marvin．And the twins, Alisa and Alan．And then Helen．Five children．I was too busy raising them to grow a garden．
Money was tight, as well as time．Often when my children were little, one of them would want something that cost too much, and I' d have to say, “Do you see a money tree outside? Money doesn't grow on trees, you now．”
Finally, all five got through high school and college and were off on their own．
One spring morning, on Mother's Day, I was working in my kitchen．Suddenly, I realized that cars were tooting their horns as they drove by．I looked out the window and there was a new tree, planted right in my yard．I thought it must be a weeping willow, because I saw things blowing around on all its branches．Then I put my glasses on－and I couldn't believe what I saw．
There was a money tree in my yard!
I went outside to look．It was true! There were dollar bills, one hundred of them, taped all over that tree．Think of' all the garden flowers I could buy with one hundred dollars! There was also a note attached: ‘‘IOU eight hours of digging time．Love, Marvin．"
Marvin kept his promise, too．He dug up a nice ten－by－fifteen foot bed for me And my other children bought me tools, ornaments , a trellis（格架）, a sunflower stepping stone and gardening books．
That was three years ago．My garden's now very pretty, just like I wanted．When I go out and tend my flowers, I don't seem to miss my children as much as I once did．I feel like they're right there with me．
