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 life style and this had led to new kinds of sicknesses． {#blank#}2{#/blank#} So they are called "diseases of civilization"．Many cancersand 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 maindifferences between life in ancient times and that of today.

      Stone Age people hunted wild animals for their meat, which hadmuch less fat than domestic ones．They ate a lotof fresh wild vegetables and fruits．They did nothave 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 moresugar．We eat twice as much fat but only one third as much protein andmuch less vitamin C.

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

A．Stone Agepeople lived a simple life.

B．But today, weenjoy eating a lot of these.

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

D．Ancient people also got lots of physical exercise.

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

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

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

    We all know what a brain is. A doctor will tell you that the brain is the organ of the body in the head. It controls our body's functions, movements, emotions and thoughts. But a brain can mean so much more.

    A brain can also simply be a smart person. If a person is called brainy, he is smart and intelligent. If a family has many children but one of them is super smart, you could say, “He's the brains in the family.” And if you are the brains behind something, you are responsible for developing or organizing something. For example, Bill Gates is the brains behind Microsoft.

    Brain trust is a group of experts who give advice. Word experts say the phrase “brain trust” became popular when Franklin D. Roosevelt first ran for president in 1932. Several professors gave him advice on social and political issues（问题）facing the U.S. These professors were called his “brain trust”.

    These ways we use the word “brain” all make sense. But other ways we use the word are not so easy to understand. For example, to understand the next brain expression, you first need to know the word “drain”. As a verb, to drain means to remove something by letting it flew away. So a brain drain may sound like a disease where the brain flows out of the ears. But, brain drain is when a country's most educated people leave their countries to live in another. The brains are, sort of, draining out of the country.

    However, if people are responsible for a great idea, you could say they brainstormed it. Here, brainstorm is not an act of weather. It is a process of thinking creatively about a complex topic. For example, business leaders may use brainstorming to create new products, and government leaders may brainstorm to solve problems.

    If people are brainwashed, it does not mean their brains are nice and clean. To brainwash means to make some accept new beliefs by using repeated pressure in a forceful or tricky way. Keep in mind that brainwash is never used in a positive way.

The Youngest Skier To The South Pole

    On Friday December 9th, a 16-year-old skier, Ameba Hempleman-Adams reached the South Pole with her father after skiing 97 miles and spending 17 nights on the ice. On the final day they skied 14 miles and afterwards Ameba said she felt “elated and tired" on reaching the South Pole.

    “The biggest challenges were the freezing cold and eating only dried food. The best bit has been experiencing what Dad does on expeditions(探险).It's the first time I've been on a difficult long journey with him and now I know what it's like. The trip brought me closer to Dad, but I also had to put up with his snoring(鼾声)which was terrible.', She added, “Would I do it again? I'm not sure. I'll have to think about that after a few nights' sleep! At times it's been really hard: I've got aching shoulders, and my back's been sore from pulling my sledge(雪橇), I've got blisters(水泡)on my feet from the boots and I've got a cold burn on my nose from my sunglasses. ______”.

    She said the most extraordinary part of the trip had been the breathtaking scenery and the sense of isolation in the Antarctic landscape.“ I've really missed my friends while I've been away and want to thank them for all their messages of support.”

    Friends and relatives who posted comments on Ameba's expedition website paid tribute(致敬)to her positive attitude which , they said ,would be an inspiration to others.

    Her father, David, said “Ameba has done amazing well. I'm proud of her. She showed real determination. She was tough and she pulled her sledge the whole way. It was a special experience to share those 97 miles with her.”

    One evening I was going back from a supermarket. As I was approaching my car, I noticed that some person came and stood beside me. He was the one that could be considered as a bum. It seemed that he had no car, no home and no job. I thought that he would ask me for money, but he did not do that, he only said: "Your car is very nice".

    After several moments of silence, I replied: "Thanks", and then the inner voice told me, "Ask him if he needs help". After a short hesitation I asked him if he needed any help. His response was astonishing. I will never forget those simple three words that I heard from him: —"Don't we all?"

    It was a true discovery to me. I needed help. Although I had money and a place to sleep, I recognized that I needed help too. Then I opened my wallet and gave him enough money to get a meal and some shelter for a day.

    Suddenly I understood that no matter how much money we have, we all need help. On the other hand, no matter how poor you are and how many material problems you have, you still might offer your help to others and you still might be giving. Even it's just a nice word, you can give that and it can be priceless to other persons.

    Maybe that man was just a homeless stranger, but to me he was more than that. Maybe he was sent by the Highest Loving Power personally to me to open my eyes and to show me that there is one thing, among all other values, which is very important and irreplaceable for each and every person. Actually, it is a true gift and it is called Giving.

    Ask any new college graduate about his immediate goals, and it is likely that he will tell you he wants a job. But it turns out that today's students are not going to be satisfied with any job. According to the latest survey, making a difference through their work is essential(必要的) to young people's happiness.

    The survey found that 72 percent of graduating college seniors believe being able to have a positive social influence through their work is essential to their happiness. Making a difference is so important to them that 45 percent say they would take a 15 percent pay cut to work at an organization that has a social or environmental influence, and 58 percent say they would take a pay cut to work for an organization whose values are the same as their own.

    Besides this, the survey found that female students are far more likely to put social influence in first place than their male classmates, echoing the results of a former study showing that female maths and science majors are more likely to say they go into those fields to make a difference.

    One reason for the emphasis(强调) on improving the world probably has to do with the culture of colleges, which encourages students to connect their studies back to real-world problems. Students are used to discussing important social issues(问题) with their friends and professors, and doing something about them in class or through volunteer activities. Once students develop those habits, they don't shut them off when graduation rolls around.
