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

The House Fairy
As young parents, my husband and I felt that at age 6 and 8, our children were old enough to be cleaning their rooms and making their beds. But they thought 36 . My complaints, repeating myself, even self-justified shouting were landing on 37 ears. I felt frustrated (沮丧的) , and very often a whole afternoon’s scolding would end with their 38 into tears, I realized I needed to 39 my methods of “mothering”.
One day while they were at school, I had great fun 40 their rooms. On their desks, in plain 41 , I left the cards: “Dear Bill (the other card was 42 to Sarah), your room was messy this morning and I’m sure you like it clean. Love, the House Fairy.” 43 arriving back, the children were 44 excited to receive the little note from the House Fairy. The next day, their rooms were fairly tidy. Sure enough, there was another note from the House Fairy 45 for them, thanking them for their nice “gift” of a clean room and 46 asking them to play a certain violin 47 . Each day, thank--you notes would be worded differently to keep the ideas 48 .
Sometimes the House Fairy would propose a little 49 : “If you can finish your homework today and 50 it before dinner, I’ d like to watch a particular television program with you tonight.” Sometimes some colored markers or other little items would be left in 51
of jobs especially well done the day 52 .
53 I can’t remember how long “the House Fairy” continued leaving her love notes. When they were no longer age appropriate (合适的), we used various versions of Post-Its. The bathroom mirror became the 54 centre of our home. Appointments, notices about visiting relatives, lesson schedules, and changes in plans could be posted.
We all benefited from and 55 the idea of sharing reminders and daily details of life through notes. I believe the true legacy of the House Fairy notes survives in our frequent and enjoyable communication.

Success is often measured by the ability to overcome adversity. But, it is often the belief of others that gives us the courage to try.
J. K. Rowling, author of the Harry Potter book series, began writing at age 6. In her biography, she remembers with great fondness when her good friend, Sean, whom she met in secondary school, became the first person to encourage her and help build the confidence that one day she would be a very good writer.
“He was the first person with whom I really discussed my serious ambition to be a writer. He was also the only person who thought I was bound to be a success at it, which meant much more to me than I ever told him at the time.”
Despite many setbacks Rowling persevered in her writing, particularly fantasy stories. But it wasn't until l990 that she first conceived the idea about Harry Potter. As she recalls, it was on a long train journey from London to Manchester that “the idea of Harry Potter simply fell into my head. To my immense frustration(沮丧), I didn't have a functioning pen with me, and I was too shy to ask anybody if I could borrow one. I think, now, that this was probably a good thing, because I simply sat and thought, for four(delayed train) hours, and all the details bubbled up in my brain, and this scrawny, black-haired, bespectacled boy who didn't know he was a wizard became more and more real to me.”
That same year, her mother passed away after a ten-year battle with multiple sclerosis, which deeply affected her writing. She went on to marry and had a daughter, but separated from her husband shortly afterwards.
During this time, Rowling was diagnosed with clinical depression. Unemployed, she completed her first novel in area cafes, where she could get her daughter to fall asleep. After being rejected by l2 publishing houses, the first Harry Potter novel was sold to a small British publishing house.
Now with seven books that have sold nearly 400 million copies in 64 languages, J. K. Rowling is the highest earning novelist in history. And it all began with her commitment to writing that was fostered by the confidence of a friend !
