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.

    Here are five tips for being a good friend.

    Listen more than you speak. Next time you ask a question, wait for the answer. Let the person tell the full story, and explain his complete answer.{#blank#}1{#/blank#}

    Keep your promises. There's nothing worse than the type of friend who leaves you hanging. Whether it's a friend get-together or meeting at the mall, they always manage to break their promises and leave you feeling upset and disappointed. This is the reason why an important part of strong friendships is the ability to trust each other.{#blank#}2{#/blank#} Therefore, next time you make a promise, keep it.

    Give advice, but only when it is asked for. By offering advice when it's not asked for, you're ignoring the needs of your friend.{#blank#}3{#/blank#}Otherwise, don't give it. Be with them, hug（拥抱）them and make them breakfast in bed, but keep your wisdom to yourself and save it for another time.

    Let your friend have other friends, too. If your best friend picks another friend over you, try to be friends with their friends too. Maybe you guys can be a group of friends!

    Everyone is always looking for new friends.{#blank#}4{#/blank#} Your loyalty（忠诚）to friendship is what the other person expects and counts on every day.

    {#blank#}5{#/blank#}  Everyone has their own faults, and they need to work through them. Don't be bad to your friend about his or her faults, but help him or her work through them while asking for help on your own as well.

A. Remember that no one is perfect.
B. But never, ever leave the old one.

C. If they want your advice, they will ask for it.

D. You are who you are, and your best friend will accept that. E. Never leave the problem alone and pretend it doesn't exist.

F. And then, when you feel that your words can add value, speak.

G. And part of this trust can only be developed if you can keep your word.
