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 disease, known as “March Madness”, refers to the yearly 65－team US men's college basketball tournament (锦标赛). {#blank#}2{#/blank#} Teams compete against each other in a single－elimination (单局淘汰) tournament that eventually crowns a national champion.

    Nearly 20 million Americans will find themselves prisoners of basketball festival madness. The fun comes partly from guessing the winners for every game. Friends compete against friends. {#blank#}3{#/blank#}  Colleagues against bosses.

    Big－name schools are usually favored to advance into the tournament.But each year there are dark horses from little－known universities.

    This adds to the madness.Watching a team from a school with 3,000 students beat a team from a school with 30,000,for many Americans,is an exciting experience.Two years ago,the little－known George Mason University was one of the final four teams. {#blank#}4{#/blank#}

The Lost Rules of Etiquette

    Etiquette, or good manners, used to be the glue that held society together. {#blank#}1{#/blank#} Sadly, these days it has mostly gone by the wayside. This list is several best rules of etiquette that have now disappeared.

    Opening the Door

    In days gone by, a gentleman would always open doors for ladies. {#blank#}2{#/blank#} This has now almost entirely disappeared-and it is not entirely the fault of the men. I have seen women laugh at men for opening a door for them. They seem to be confusing manners with chauvinism（大男子主义）.

    Writing Thank-You Notes

    In days gone by, whenever a person received a gift, they would write a thank-you note as soon as possible. {#blank#}3{#/blank#} Parents would sit children down after a birthday or Christmas and coach them in their first thank-you note. It is a shame that gift giving has now become a virtual obligation and the idea of a thank-you note would be laughed at.

    {#blank#}4{#/blank#}

    We seem to have completely lost the concept of correct timing when it comes to parties these days. {#blank#}5{#/blank#} After all, a party normally has a guest of honor-this is usually the oldest woman present. It was considered extremely rude in the past to leave a party before the guest of honor-and once the guest of honor left, it was a signal to all that they should begin their on preparations to leave.

    Every one complains（抱怨）. Even if you argue that you are the happiest person in the world, you still complain sometimes.

    Sometimes you complain: without even realizing it, but rarely is it ever helpful. {#blank#}1{#/blank#}Here are some tips to stop complaint and give up the negative thoughts: {#blank#}2{#/blank#}When you find yourself thinking or saying a negative comment about something or someone, stop and force yourself to say something positive instead. Seek the help of a cheerful friend to change you when you complain and help you to see the positive in the situation.

    Make a list of things that we are grateful for.

    We often complain about the things we don't have without noticing those things we already have.

    Be grateful for what we have in our life because we are lucky simply for being ourselves. {#blank#}3{#/blank#}

    Learn to adapt to the changes. There are many things we can't change.{#blank#}4{#/blank#} Always find the positive side of each situation, regardless of however difficult the situation is. With parents' and friends' support, we can survive any life changes.

    Find what makes you happy.

    {#blank#}5{#/blank#}Maybe it is time to make the hard decision to move on to another job or career.

    Uncover what your biggest complaints are about and see if you can change the situation to make you happy. Choose happiness, focus on the positive, and be kind always!

A. Sometimes this list can be easy, full of hobbies you enjoy.

B. Are you constantly complaining about your present job?

C. So how can you manage to force yourselves to end complaining?

D. Set down things we are thankful for and we'll see that we don't have any reason to complain.

Were you actually surprised by this one?

Actually, distracted driving accidents, including those caused by the use of handheld devices, form the No. 1 killer of teens, according to the NHTSA and others.

Drive when you're tired.

Avoid driving when you're tired, since you will have slower reaction times and you are very likely to fall asleep at the wheel. If you're exhausted and your body needs sleep, it is going to get it, one way or another. {#blank#}4{#/blank#}If you're already in the car, pull over and take a nap and then continue when you've woken up. Having someone with you in the car can help prevent accidents, since you are more likely to be alert if you have company.

Keep an eye on the kids.
