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.

Some might think all of the apps are distracting, but the apps actually make iPads more efficient. {#blank#}4{#/blank#} Textbooks cannot do those tasks, but iPads can easily do them with just a tap of the fingertip.

    Lastly, iPads are a better choice for schools instead of textbooks because these devices allow students to access their learning anywhere at any time. {#blank#}5{#/blank#} With iPads, they find it easier to get their homework done.

Can zoos ever be animal-friendly?

    The topic of our last class discussion was “How can zoos provide animals with a good life?” Everyone believed it was impossible for zoos to give animals a caring environment. Our teacher suggested that visiting a modern zoo might give us a new point of view.

    {#blank#}1{#/blank#} In our discussion, many people said that zoos were full of smelly cages with unhappy animals living in. Cleveland Metroparks Zoo, however, was set in an attractive, open environment. Trees and flowers had been planted around the park. {#blank#}2{#/blank#}

    At school, some people accused（指责）zoos of exploiting（剥削）animals for money but at Cleveland Metroparks Zoo, as I see it, nothing could be further from the truth. {#blank#}3{#/blank#}

    Before I visited Cleveland Metroparks Zoo, I wasn't sure about the rights and wrongs of zoos. {#blank#}4{#/blank#} I feel that, although zoos can't provide the freedom of the wild, they can be animal-friendly by giving animals a safe and caring environment. As long as they do this well, to my mind they make a good contribution（贡献）to animal health. They also play an important part in educating us about wildlife. {#blank#}5{#/blank#}

    On the bus back to school, we all agreed that what we liked most was the zoo's environment and we would recommend（推荐）it for next year's group.

A. It is difficult for the zoo to raise animals.

B. More and more animals enjoy their wild homes.

D. Most of the money is used to improve conditions at the zoo.

E. I went to the zoo and was pleasantly surprised by what I found.

F. In my opinion, the animals, rather than seeming upset, were pleased.

G. It was difficult to say how a zoo could really make up for animals' loss of freedom.
