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

What does it mean to say that we live in a world of persuasion? It means that we live among competing interests. Your roommate’s need to study for an exam may take priority over pizza. Your instructor may have good reasons not to change your grade.
In such a world, persuasion is the art of getting others to give fair and favorable consideration to our points of view. When we persuade, we want to influence how others believe and behave. We may not always prevail — other points of view may be more persuasive, depending on the listener, the situ­ation, and the merit of the case. But when we practice the art of persuasion, we try to ensure that our position receives the attention it deserves.
Some people, however, object to the very idea of persuasion. They may regard it as an unwelcome interruption into their lives. Just the opposite, we believe that persuasion is unavoidable — to live is to persuade. Persuasion may be ethical (合乎道义的) or unethical, selfless or selfish, inspiring or degrad­ing. Persuaders may enlighten our minds or get our vulnerability(脆弱之处). Ethical persuasion, however, calls on sound reasoning and is sensitive to the feelings and needs of listeners. Such persuasion can help us apply the wisdom of the past to the decisions we now must make. Therefore, the most basic part of edu­cation is learning to resist the one kind of persuasion and to encourage and practice the other.
Beyond its personal importance to us, persuasion is necessary to society. The right to persuade and be persuaded is the bedrock of the American political system, guaranteed by the First Amendment to the Constitution.
According to the passage, persuasion means ______.

A.changing others’ points of view
B.exercising power over other people
C.getting people to agree with you and do what you want
D.getting other people to consider your point of view

A.win B.talk C.compare D.expect

The purchase is instantly charged to your credit card.
Ever seen someone wearing something and wished you knew where to get it? Soon it will be easy with PicCommerce, new technology that uses image-recognition software. Here’s how it works.

Wild weather, unexpected coral reefs and dangerous sea creatures… these are the nightmares (噩梦) you can imagine a teenager on a solo voyage (独自旅行) around the world might suffer from. But for Laura Dekker, sailing around the globe seems less a price to be paid than a prize to be treasured.
As the 19-year-old Dutch sailor said in Maidentrip, a documentary released last year about her experience of becoming the youngest person to sail around the world alone in 2012, “I was born on a boat. I lived my first five years at sea. And ever since, all I have wanted is to return to that life.”
With her yacht Guppy, Dekker began her journey at 14 and sailed 50,004 kilometers in 519 days.
The flying fish keeping her company, the dolphins following in her wake and the warm days spent on deck playing the flute as she watched another unforgettable sunset were enough to make others jealous.
But these didn’t always go well. There were terrible moments in which Dekker feared death. On one occasion, a whale almost turned Guppy over. Another time, she battled extreme winds and Guppy surfed down 8-meter-high waves.
Out on the open sea alone, she also got used to living without a fridge, a flushing toilet, and a hot shower.
“As a human being you don’t need much,” she told Stuff.co.nz. “ They might make life more comfortable, but you really don’t need them to be happy.”
In fact, her outlook on life was shaped by the trip. “I wanted the storms. I wanted the calms. I wanted to feel loneliness,” she told The New York Times. “And now I know all these things. It’s the end of the dream I had as a child, and it’s the beginning of my life as a sailor.”
According to the text, in which year did Dekker begin her journey of 50,004 kilometers at sea?

A.In 2012 B.In 2010
C.In 2009 D.In 2011

The method the author uses to develop Paragraph 5 is ________.

C.giving examples D.making comparisons
