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

You may picture firefighters holding a hose (水管) outside of a burning building, but the Golden Eagles Hotshots don’t fight fires quite that way. When they go into action, you may not even see a fire truck.

The Hotshots are firefighters who battle fires in wildness areas. But don’t think you’ll only find them in their home state California. Wherever there is a national wildfire emergency, the Golden Eagles Hotshots could be there.

But these firefighters don’t work the same way as firefighters in a big city. They work in areas where there are a large number of trees, bushes, and grass. They climb up and down steep hills to clear brush and burnable debris（残骸）. They sometimes use water, but they often fight fire with fire!

They do that by lighting what are called “backfires,” which are small, controlled fires that burn up fuel in the path of large wildfires. That way, when the wildfire gets there, it has nothing to burn and nowhere to go, because all the burnable fuel has already gone up in smoke.

The Hotshots also clear away fuel using old-fashioned hard work. For example, they use a saw to cut away trees and heavy brush that could catch fire.

Of course there are times when the Golden Eagles Hotshots do have trucks to supply water to the fires. But the water is limited, and these guys have to rely on hard work more than anything. Physical fitness is very important. They have to be in great physical shape to handle steep hills and difficult terrain(地形) while carrying a 60-pound pack.

The Golden Eagles Hotshots definitely work hard for their pay. But thanks to their efforts, many lives have been saved, many houses have not burned, and countless trees are still standing.

1.67. The firefighters mentioned in the passenger. 

2.68. According to the passage, why do the firefighters light “backfires”?

3.69. What can we learn about the Golden Eagles Hotshots?

4.70. What is the author’s attitude towards the Golden Eagles Hotshots?

Most Americans don’t like to get advice from members of their family. When they need advice, they don’t usually ask people they know. Instead, many Americans write letters to newspapers and magazines which advice give on many subjects, including family problems, the use of language, health, cooking, child care, clothes, how to buy a house or a car, and so on.

Most newspapers regularly print letters from readers with problems. Along with the letters are answers written by people who are supposed to solve (解决) such problems. Some of these writers are doctors; others are lawyers or educators. But two of the most famous writers of advice are women without special training for this kind of work. One of them answers letters addressed to “Dear Abby”. The other is addressed as “Dear Ann Landers”. Experience is their preparation for giving advice.

There is one writer who has not lived long enough to have much experience. She is a girl named Angel Caveliere, who started writing advice for newspaper readers at the age of ten. Her advice to young readers, now appears regularly in the Philadelphia Bulletin in a column called DEAR ANGEL.

Yesterday was our three-year anniversary. We didn’t do anything romantic: we just walked hand in hand and talked about our past and future. This was pretty much what I had expected.

　　Andy is unromantic guy: no sweet words or roses. Smart as he is, he is a little bit shy expressing his love. However, I am an outspoken girl who likes to show her feelings directly. So needless to say, I often feel that is insensitive. I envy other girls who are surrounded by sweet words from their boyfriends.

　　I was in this sullen mood until I heard a beautiful sentence one day: “If someone does not love you in the way you like, it does not mean that he does not love you.” This simple but sensible sentence made me think about our happy days and recall his deep concern for me.

　　One cold winter night, I got a high fever. He hurried to my dorm and took me to the hospital. He was in such a hurry that he even forgot to wear socks. Upon arrival, he ran through the hospital handling all the formalities(手续). When I was put on a drip（输液）, he told me interesting stories to make me happy. Being held in his warm arms and listening to his tender voice, I had never felt so safe and comfortable. Gradually, I felt asleep. When I woke up 15 minutes later, he was still whispering to me. He explained that if he had stopped talking I would have waken up. At that moment, I found love in his sparkling eyes.

　　Another time, I had a bad quarrel with my best friend. Although I knew it was my fault, I refused to admit it. I was angry when he insisted I apologize to her. He said that it was difficult to admit a mistake, but this was what everyone should do. The next morning, I apologized to my friend and asked for her forgiveness.

　　My unromantic boyfriend cares about my health like my father, understand me like my mother and helps me like my elder brother.
