Both men and women are living longer these days in industrialized countries. {#blank#}1{#/blank#} In general, they can expect to live six or seven years more than men. One reason for this is biological.

    One important biological factor(因素) that helps women live longer is the difference in hormones between men and women. {#blank#}2{#/blank#} Between the ages of about 12 and 50, women produce hormones that are involved in fertility(生育能力). These hormones also have a positive effect on the heart and the blood flow. In fact, women are less likely to have high blood pressure or to die from heart attacks.

    {#blank#}3{#/blank#} They help the body defend itself against some kinds of infections. This means that women generally get sick less often and less seriously than men. The common cold is a good example: women, on average, get fewer colds than men.

    {#blank#}4{#/blank#} Scientists are still not exactly sure how genes influence aging, but they believe they do. Some think that a woman's body cells have a tendency(倾向) to age more slowly than a man's. Others think that a man' s body cells have a tendency to age more quickly. {#blank#}5{#/blank#}

A. However, women, on average, live longer.

B. The biological factor plays an important part.

C. Women are also helped by their female genes.

D. The female hormones also protect the body in another way.

E. Recent research seems to support both of these possibilities.

F. Therefore, women are more healthy than men and can live a better life.

G. Hormones are chemicals which are produced by the body to control various body functions.

    More people are dying from hepatitis(肝炎) than AIDS and tuberculosis, warns World Health Organization. The World Health Organization(WHO) has urged for action to wipe out hepatitis as ongoing illness worsens.

    In its first global report on the infection, it said the number of people dying from treatable forms of the disease, often caused by alcohol and drug abuse, is rising. Viral hepatitis is believed to have killed 1.34 million people in 2015, and amount similar to that of tuberculosis.

    But while those are both falling, hepatitis deaths are on the rise—increasing by 22 per cent since the turn of the century.

    However, most of the 325 million people infected are completely unaware they have the virus and some lack life-saving medicines. As a result, millions of people are at risk of a slow progression to chronic liver disease, cancer and even death, the WHO warned, Margaret Chan, director general of the WHO, said: “Viral hepatitis is now a major public health challenge that requires an urgent response.”

    The two most common forms, which are responsible for 96 per cent of deaths from the disease, are hepatitis B(HBV) and hepatitis C (HCV)

    HBV can be passed on through unprotected sex and bodily fluids(液体). It requires life-long treatment with a drug commonly used to battle HIV. New infections of this type of the disease are falling, thanks to a vaccine given to 84 per cent of newborns across the world. However, just nine per cent of sufferers know they are infected, meaning many go under the radar and miss out on treatment.

    HCV, usually spread through blood-to-blood contact with an infected person, can be cured relatively swiftly, but many patients across the world are unable to afford the medication. Around 1.75 million people were newly infected with HCV in 2015, bringing the global total to 71 million, figures suggests. But four fifths of those infected with this type of the disease are unaware they are suffering, the WHO warned.

    Experts looking at the cases have identified unsafe healthcare procedure and injection drug use as the top causes. Gottfried Hirnschall, director of WHO's Department of HIV and the Global Hepatitis Programme, said the WHO was working with governments, drugmakers and diagnostics companies to improve access.

    He added: More countries are making hepatitis services available for people in need—a diagnostic test cost less than $1 (78p) and the cure for hepatitis C can be below $ 200 (￡156). But the data clearly highlight the urgency with which we must address the remaining gaps in testing and treatment.

    Charles Gore, president of the World Hepatitis Alliance, said: “For the first time in the history of viral hepatitis, we have an understanding of the true impact of the disease.”

    On Friday, the Food and Drug Administration (FDA) released two proposals to improve food safety. The regulations are a response to a series of recent foodborne illnesses. The FDA hopes these new rules will prevent problems of food in the earliest period of production, before the contaminated（受污染的）food causes consumers to get sick.

    Over the past decade, foodborne illnesses have caused many people to get sick. Food like spinach（菠菜）, ground beef and cantaloupes（甜瓜）has been sent back to producers, because it is bound to contain germs and bacteria that cause illnesses.

    Among the most common problems are dangerous bacteria that cause stomach pains and food poisoning. Often these illnesses occur when food is undercooked or improperly prepared. While not all illnesses are reported, the FDA estimates that nearly 130,000 Americans a year are hospitalized for food-related problems.

    The two new rules proposed by the FDA are called Preventive Controls for Human Food and Standards for Produce Safety. Each rule is described in detail on the FDA's website. Readers can submit comments, which the FDA will use as feedback to mike future adjustments to the proposals.

    The first rule demands manufacturers should have formal plans for preventing contamination and for fixing problems when contamination occurs. This regulation is applied to food produced in the US and overseas.

    The second rule k specific to food that is eaten raw. It requires strict standards of growing harvesting, and packing fruit and vegetables. Workers must make sure the materials used in soil are safe and free of contamination.

    The FDA believes these new rules will not just improve Americans' health but also make a positive economic impact. The regulations can lead to major savings in medical costs for people who get sick because of the contamination food.

    If manufacturers are able to fix problems at source, they will prevent future issuer However, putting the proposals into action will lake lime and money.

    Can you be too beautiful? It is hardly a problem that most of us have to bother — as much as we might like to dream that it were the case.

    Yet the blessings and curses of beauty have been a long-standing interest in psychology. Do those blessed with shiny faces and an attractive body live in a cloud of appreciation — or does it sometimes pay to be ordinary?

    At the most basic level, beauty might be thought to carry a kind of halo (光环) around it; we see that someone has one good quality, and by association, our deep mind may assume that they have other good ones too.

    Even in the courts, a pleasing appearance can work its magic. Attractive criminals are likely to get less strict sentences, or to escape punishment entirely; attractive plaintiffs (原告), meanwhile, are more likely to win their case and get bigger financial settlements. “It's an effect seen everywhere,” says Walker.

    But if beauty pays in most circumstances, there are still situations where it can have opposite results. While attractive men may be considered better leaders, for instance, hidden sexist prejudices (偏见) can work against attractive women, making them less likely to be hired for high-level jobs that require power. And as you might expect, good-looking people of both sexes run into envy — one study found that if you are interviewed by someone of the same sex, they may be less likely to employ you if they judge that you are more attractive than they are.

    More worryingly, being beautiful or handsome could harm your medical care. We tend to link good looks to health, meaning that illnesses are often taken less seriously when they affect the good-looking. When treating people for pain, for instance, doctors tend to take less care over the more attractive people.

    Ultimately, scientists point out that focusing too much on your appearance can itself be harmful if it creates stress and anxiety — even for those already blessed with good looks. “If you are crazy about attractiveness, it may affect your experience and interactions,” she says. It's an outdated saying, but no amount of beauty can make up for a bad personality. As the writer Dorothy Parker put it so elegantly: “Beauty is only skin deep, but ugly goes clean to the bone.”

    Starbucks will stop using plastic straws from its stores globally by 2020, in a nod to the growing push for businesses to be more environmentally friendly. The Seattle-based company said on Monday it will instead use straws made from other materials, and lids designed not to need straws. McDonald's also recently said it would switch to paper straws in the UK and Ireland by next year, and test alternatives to plastic straws in some US locations. In February, Dunkin' Donuts said that it would refuse polystyrene foam (塑料泡沫) cups from its stores by 2020.

    Environmental activists have been pressuring businesses to ditch plastic straws because they can end up in the ocean and hurt marine life. The push gained great support after a video in 2015 showed rescuers removing a straw from a sea turtle's nose in great detail. Local governments have also been looking at the issue. Last week, Seattle's ban on single-use plastic straws and utensils in food service outlets took effect, and Starbucks says it already offers alternative straws there. Similar proposals are being considered elsewhere, including New York and San Francisco.

    While straws have become a highly-concerned issue, they make up only about 4% of the plastic trash by number of pieces, and far less by weight. Straws add up to only about 2,000 tons of the nearly 9m tons of plastic waste that hits waters each year.
