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．Stone Age people lived a simple life.

B．But today, we enjoy 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”.

Ways to Find the Happiness in Front of You

    We struggle with war, poverty, global warming. {#blank#}1{#/blank#}Famous people have wonderful lives, but you don't, and the "if only's" threaten to win the day: "My life would be sweet if only I were richer, had a better job..."

    {#blank#}2{#/blank#}And it doesn't care how much money you have or what the circumstances of your life are. Look through the suggestions on how to look on the bright side and find the happiness in front of you.

    If I'm feeling low, one of the best ways I know to cheer up is to make a love list. It's simple, just a list of every single person I love. Then I can put it in a pocket to take with me on a tough day, or just keep it in mind as I get on with my life.

Find Lost Friends

    I recently took some time to seek out people that I've lost touch with over the years.{#blank#}4{#/blank#}. Within 24 hours I had baby pictures and recent histories. But the interesting thing was that all the people I got in touch with had been thinking about contacting me a couple of days before getting my email.

Think Positively

    {#blank#}5{#/blank#}I'm not saying your problems are over, but simply looking at the world through rose-colored glasses means that half your problems will look like exciting challenges, and the other half you'll probably realize aren't problems at all, just facts of life.

A. Create a love list

B. But happiness is all around you.

C. Wish upon a star

D. I wonder whether they still remember me.

G. It took only a little time to shoot a few quick emails around the country.

Testing the five-second rule

    You may have seen a friend drop food on the floor, pick it up, and eat it, while declaring, “Five-second rule! ” It's said that food dropped on the floor for five seconds or less is still likely to be clean. {#blank#}1{#/blank#}.

    Students at Britain's Aston University, led by microbiology professor Anthony Hilton, tested the rule and found it to have some scientific basis. The study's results show that food dropped for five seconds is less likely to contain bacteria than if it sits there for longer, according to Hilton.

    The students also found that the type of flooring where the dropped food lands has an effect. {#blank#}2{#/blank#} Bacteria are most likely to transfer from tiled (铺瓷砖的) surfaces to moist food when the food has stood there for more than five seconds.

    {#blank#}3{#/blank#} Therefore, consumers should still be cautious. “However, the findings of this study will bring some light relief to those who have been employing the five-second rule for years, despite a general consensus that it is purely a myth,” professor Hilton said in a statement.

    The research team at Aston also surveyed 500 people to find out who employs the five-second rule. Of the people surveyed, 87% said they would eat food dropped on the floor, or have done so in the past. {#blank#}4{#/blank#} “Our study showed people are also more likely to follow the five-second rule, which our research has shown to be much more than an old wives' tale,” Hilton says.

    Still, scientists say you should be careful about eating food dropped on the floor, especially if you have doubts about the cleanliness of the surface. {#blank#}5{#/blank#}

A. But is that true?

B. Carpeted surfaces posed the lowest risk.

C. Of those people, the majority were women.

D. We've just lost our last excuse to eat food off the floor.

E. Usually people recover from the infection in five to ten days.

F. There is still a risk of infection if certain bacteria are present on the dropped surface.

G. A biologist points out that one in six Americans get sick from food poisoning every year.

    Among the teachers in my life，there is one person I called“Old Uncle”．I first met with him a decade ago when I was in primary school．{#blank#}1{#/blank#} During those rides，Old Uncle told me about his life．

    {#blank#}2{#/blank#} He made a living by riding tricycles(三轮车)and raised the children on his own．His daughter gave up the chance to go to college so that the younger brother would have money to go after his future．Later on，she became a nurse at a hospital through her hard work．

    For each ride，Old Uncle should charge me five yuan．However，he insisted on accepting only four from me．In our conversations，he told me to always have a good heart，to be a good student，child and person．{#blank#}3{#/blank#} More movingly，every time he took me to school，he asked whether I had eaten breakfast and would try to offer me biscuits．

    Old Uncle was one of the early people who led me to explore pain and suffering，  unintentionally and naturally，through stories and giving．He didn't complain(抱怨)about the hardships he had suffered in life．{#blank#}4{#/blank#} Ten years later as I thought back to the scene，I came to realize that Old Uncle and I shared space，and connected through our spirit．{#blank#}5{#/blank#}

A．I knew that Old Uncle lived a difficult life．

B．Old Uncle would pay the price for his behavior．

C．He took me to school in his tricycle every morning．

D．Old Uncle guided me to see the beauty of human nature．

E．Instead，he shared peacefully as if they weren't happening on him．

F．His wife had passed away when their two children were still young．

G．He said this with so much caring that I listened with my whole heart．
