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(易受影響性),” 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(曬黑)without sunscreen, their weight, and their history of skin cancer, smoking, and alcohol drinking. The study group consisted of 52 fraternal(異卵雙生)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.

Marriages improve after children grow up and move out，according to an academic study, which suggests an “empty nest” is not always a bad thing.
Popular wisdom has it that parents’ relationships may suffer once their young fly the coop, because they feel they have lost their purpose in life.However, a new study by researchers at the University of California, Berkeley, has found that many couples actually feel happier when their children leave home because they are able to enjoy spending time together.
In total,123 American mothers born in the 1930s were tracked for 18 years and asked to rate their satisfaction levels shortly after marrying, when they were bringing up babies, once their children reached their teenage years and finally at age 61, when almost all had “empty nests”．
Although not all said they were happier in general, most claimed their marriages had improved since their children had left home. Researchers believe this is not just because the spouses were spending more time together, but because they were able to enjoy each other’s company more.
One of the participants in the study，which is published in the journal Psychological Science，said：“Once the kids grow up...there’s some of that stress removed...that responsibility removed，so things are a little more relaxed.”
Psychologist Sara Gorchoff，who carried out the investigation，said: “The take­home message for couples with young children is ‘hang in there’．” Her co­author Oliver John added：“Don’t wait until your kids leave home to schedule quality time with your partner.”
However, Dr Dorothy Rowe，from the British Psychological Society，said the effects of living in an “empty nest” will depend on the parents’ relationship with their children.“If you’re just waiting for them to leave home so you can get on with your life，then of course you’ll be pleased to see them go,” she said, “But if you’ve built your life around your children you’ll be terribly lonely.For some parents，their world falls apart when their children leave.”
【小題1】It is commonly believed that___________.

A．marriages improve after children leave home
B．a(chǎn)n “empty nest” is always a happy thing
C．parents’ relationships may suffer once their young grow up and move out
D．parents will be pleased after their children leave home
【小題2】When did many couples feel happier according to the study?

B．Shortly after marrying.
C．Once their children reached their teenage years.
D．When they were bringing up babies.
【小題3】Marriages improve after children fly the coop not because___________.
A．many couples are able to spend time together
B．many couples are able to enjoy each other’s company
C．things are a little more relaxed
D．many couples needn’t work at all
【小題4】The author of the passage tends to agree that____________.
A．parents should build their life around their kids
B．parents should schedule quality time with each other before kids leave home
C．parents’ relationship with their kids has no effect on marriages at all
D．parents should be pleased to see their kids leave home
