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

        One important biological factorthat 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 producehormones that are involved in fertility(生育能力). These hormones also have a positive effect on the heart andblood flow. In fact, women are less likely to have high blood pressure or to diefrom heart attacks.

{#blank#}3{#/blank#}  Theyhelp the body defend itselfagainst some kinds of infections. This means that women generally get sick lessoften and less seriously than men. The common cold is a good example: women, onaverage, get fewer colds than men.

{#blank#}4{#/blank#}Scientists are still not exactly sure howinfluence aging, but they believe that they do. Some think that a woman's body cellshave a tendency(向) to age more slowlythan 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 carious body functions.

    Every animal sleeps,but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month.{#blank#}1{#/blank#} 

    One idea is that sleep helps us strengthen new memories. {#blank#}2{#/blank#} We  know that, while awake,fresh memories are recorded by reinforcing (加强)connections between brain cells, but the  memory processes that take place while we sleep  have been unclear.

    Support is growing for a theory that sleep evolved so that connections between neurons(神经元)in the brain can be weakened overnight, making room for fresh memories to form the next day.  {#blank#}3{#/blank#}

    Now we have the most direct evidence yet that he is right. {#blank#}4{#/blank#} The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep,showing that the connections between neurons weaken while sleeping.

If Tononi's theory is right, it would explain why, when we miss a night's, we find it harder the next day to concentrate and learn new information —our brains may have smaller room for new experiences.

    Their research also suggests how we may build lasting memories over time even though the synapscs become thinner. The team discovered that some synapses seem to be protected and stayed the same size. {#blank#}5{#/blank#}  “You keep what matters,” Tononi says.

    I feel very excited at the thought that in another week I'll be with you again on holiday.

    {#blank#}1{#/blank#} My host and my fellow-students are all very nice to me, but as they say in England, “There's no place like home”, and I think you will feel this above all at Christmas time.

    I'm leaving here early on Thursday, the 23^rd, and I'll be arriving in Paris on Friday morning. {#blank#}2{#/blank#} Please meet me at the station. In some of my earlier letters I have told you all about the other students here. {#blank#}3{#/blank#}  Because he has no friends in England except me. He is a very nice boy. I know you will like him and I feel sure he will enjoy Christmas with us. {#blank#}4{#/blank#} Please let me know soon if that's all right. I've got some Christmas presents for you all, but I'm not going to tell you what they are, so it will be a surprise.

    {#blank#}5{#/blank#} I hope you are all keeping well. See that father always puts on his big coat when he goes out so that he will not catch a cold. We don't want him ill for Christmas.

A. I will have him spend Christmas with us.

B. But I haven't invited him yet.

C. I enjoy my stay in England very much indeed.

D. How are you all at home?

E. So I'll be home about lunch time.

F. Well, I want to ask my Canadian friend, Jan, to come and spend Christmas.

G. Things at home are much better than things in other places.

How to Do Man-on-the Street Interviews

    The man-on-the-street interview is an interview in which a reporter hits the streets with a cameraman to interview people on the spot.{#blank#}1{#/blank#} But with these tips, your first man-on-the-street interview experience can be easy.

    When your boss or professor sends you out to do man-on-the –street interviews for a story, think about the topic and develop a list of about ten general questions relating to it. For example, if your topic is about environmental problems in America, you might ask, “Why do you think environmental protection is important in America?”{#blank#}2{#/blank#}

    Hit the streets with confidence.{#blank#}3{#/blank#} Say, “Excuse me, I work for XYZ News, and I was wondering if you could share your opinion about this topic,” This is a quick way to get people to warm up to you.

    Move on to the next person if someone tells you she is not interested in talking on camera. Don't get discouraged.

     {#blank#}4{#/blank#} Each interview that you get on the street shouldn't be longer than ten minutes. As soon as you get the answer you need, move on to the next person. Make sure that as you go from interview to interview, you are getting a variety of answers. If everyone is giving you the same answer, you won't be able to use it. A safe number of interviews to conduct is about six to ten.{#blank#}5{#/blank#}

    If your news station or school requires interviewees to sign release forms to appear on the air, don't leave work without them.

A. Limit your time.

B. As you approach people, be polite.

C. If you don't own a camera, you can buy one.

D. For new reporters, this can seem like a challenging task.

E. To get good and useful results, ask them the same question.

F. That number of interviews should give you all the answers you need.

G. With a question like this, you will get more than a ‘Yes” or “No” reply.

    If you were like most kids, your mother told you there were three no-no's when it came to your fingers: Don't put them in an electrical outlet, don't stick them up your nose ( at least not in public ), and don't use them when you are counting.{#blank#}1{#/blank#}But experts in education and cognition now believe that using your fingers to do math is not only a perfectly good idea but may even help children become superior students.

    It certainly makes sense. When children count on their fingers, they take an abstract concept— mathematics—and translate it into the most basic and visual form.{#blank#}2{#/blank#} Even when we aren't actually counting on them, they still can help us on math problem,

    {#blank#}3{#/blank#}It activates when we respond to heat, pressure, pain, or the use of a given finger. Studying brain scans, researchers discovered that when students aged 8 to 13 work on subtraction (减法) equations, this region “lights up” on the scans, even if the students aren't using their fingers. The more complex the problem, the more activities are detected.

    The connection between finger use and math ability has been shown on old-fashioned math tests as well. With their eyes closed, first graders were asked to identify which of their fingers a researcher was touching,{#blank#}4{#/blank#}When college students were given the same quiz, the highest scores once again performed best on calculation tests.

    So what does all this mean? For one thing, parents and teachers shouldn't discourage children from counting on their fingers.{#blank#}5{#/blank#}Memorizing the multiplication tables may help, but it is not the best option. “I would like to see interesting and creative representations of ideas.” says Jo Boaler, a professor of math education.

    Recently, a series of activities have been designed to strengthen students' perception of their fingers. Maybe in the near future, there will be only two no-no ¹s regarding the use of fingers.

A. The first two laws of fingers are as true as ever.

B. There is a section of the brain, called the somatosensory finger area.

C. Researchers also stress that students simply learn better using visual tools.

D. Researchers are unimpressed by those students who finish quickly as well.

E. In fact, experts believe the brain is able to “see” a representation of our fingers.

F. That may sound simplistic, but the researchers offer an interesting explanation.

G. Researchers found those scoring highest on the finger-ID questions scored higher on a math test.

    It should come as no surprise that the more stressed parents are at work, the greater the burden on their family is. {#blank#}1{#/blank#} After all, the more time parents spend working, the less time and energy they have to plan and prepare healthful meals. Previously, most studies have focused on the role of working mothers while fathers were ignored. {#blank#}2{#/blank#} It adds a new wrinkle to the relationship between work stress and family nutrition. Mom's work related stress is still a central factor in how well families eat because they typically do most of the food shopping and cooking. {#blank#}3{#/blank#}

    The study finds that when mom or dad experience high levels of work related stress, their families are eating one-and-a-half fewer family meals per week, and the parents themselves report eating fewer fruits and vegetables, more fast food, and are less likely to eat breakfast regularly.

    It's worth noting that the study looks mainly at low income families who belong to ethnic or minority groups. {#blank#}4{#/blank#} But the implications are wide-ranging.

    {#blank#}5{#/blank#} Teaching kids, especially teenagers, to help with grocery shopping and to cook actual meals, instead of just putting a frozen pizza in the microwave, could be an important piece of the puzzle in helping families improve their eating habits.

A. But dad's work related stress has a large impact, too.

B. As to family nutrition, the entire family plays a role, even kids.

C. Yet, the kid's stress may affect the families' nutrition, too.

D. So the findings don't necessarily apply directly to other types of families.

E. It's also probably not a surprise that this can negatively affect a family's nutrition.

F. Now, a study looks at the family as a whole and at the role of fathers in particular.

G. It is parents who give their kids a good model to develop a good eating habit.
