Recently some American scientists have given a useful piece of advice to people in industrialized nations．They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago．{#blank#}1{#/blank#}

    The scientists say that the human life has changed greatly．Our bodies have not been able to deal with these changes in lifestyle and this had led to new kinds of sicknesses．{#blank#}2{#/blank#} So they are called "diseases of civilization"．Many cancers and diseases of the blood system are examples of such diseases.

    Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none．{#blank#}3{#/blank#} However, a change in food is one of the main differences between life in ancient times and that of today.

    Stone Age people hunted wild animals for their meat, which had much less fat than domestic ones．They ate a lot of fresh wild vegetables and fruits．They did not have milk or any other dairy products, and they made very little use of grains．{#blank#}4{#/blank#} We eat six times more salt than our ancestors．We eat more sugar．We eat twice as much fat but only one third as much protein and much less vitamin C.

    {#blank#}5{#/blank#} But scientists say that we would be much healthier if we eat much the same way the ancient people did, cutting the amount of fatty, salty and sweet food.

 A．Modern people used to suffer from "diseases of civilization".

 B．People today probably don't want to live like our ancestors.

 C．These new sicknesses were not known in ancient times.

 D．Ancient people also got lots of physical exercise.

 E．In that case, they would live much healthier.

 F．But today, we enjoy eating a lot of these.

 G．Stone Age people lived a simple life.

    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#}

Because there can be fortunate accidents, like bumping into an old friend you haven't seen for years and whose address you've lost. {#blank#}4{#/blank#}.

    No doubt a good many words in the list will be familiar to you, but do you use them, or do they remain the “property” of others? {#blank#}5{#/blank#}Try to make these words your own, as companions or friendly rivals of the ones you have owned in the past.

How to Survive Being Stuck in a Lift

    Being stuck in a lift, also known as an elevator, can sometimes be scary, especially if you are a fan of those kinds of movies which have a lot of elevator tragedies. You may think being stuck in an elevator in real life is not like in the movies. {#blank#}1{#/blank#}

    Remain calm and do not panic! You may have heard of this a lot of times and it is true that panicking will do you no good. {#blank#}2{#/blank#}

    Press each of the floor buttons one by one. Then, try the "doors open" button. If none of the buttons works, the lift is broken, and you need to let someone know about it.

    See if your phone has any reception or Internet. {#blank#}3{#/blank#} If you have WiFi connection, contact a family member or friend. Don't forget to tell them what the address is of the building and possibly which elevator you are stuck in. If your phone is not available, the following tips can help you.

    Look through the gap between the doors of the lift. If you can see light between the doors, the lift has stopped near a floor, and you should be able to shout for help and be released. Do not try to force the doors open yourself. If you can't see light between the doors, the lift has stopped between floors, and no one will be able to let you out if you scream for help. Look for an emergency telephone. If there is no telephone, press the alarm button repeatedly. {#blank#}4{#/blank#}

    {#blank#}5{#/blank#} If you have waited for more than half an hour and nobody has come to get you out, shout and bang the inside walls of the lift. If no one is responding to you, then you'll have to accept that you will be in the lift overnight. If this happens, make yourself as comfortable as possible to save your energy. By morning, the building should be full again. You can try to get some help then.

A. Check the time.

B. It will cause you not to be able to think clearly.

C. Eventually, someone should hear you and get help.

D. Here are some tips to help you survive.

E. However, it is still a vital thing to know how to survive if it ever happens to you.
