Two American scientists told the people in industrial nations that they would be much healthier if they ate more of the same kind of foods eaten by humans living more than 10,000 years ago. 
The scientists say that the human body has changed very little since human first appeared on earth, but the way we live has changed greatly. Our body has not been able to deal with these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times. So they are called “diseases of civilization”. Many cancers and diseases of the blood system, including heart attacks and strokes(中风) are examples of such diseases. 
Scientists noted that early stone-age people used very little alcohol or tobacco, probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and life today. 
Stone-age people hunted wild animals for their meat, which had much less fat than farm animals. They also ate a lot of fresh wild vegetables, and fruits. They did not use milk and other dairy products, and they made very little use of grains. But today, we eat a large amount of dairy products and grain foods. We eat six times more salt than stone-age people. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C. 
People today probably do not want to live as people thousands of years ago did, but scientists say that we would be much healthier if we ate as those ancient people did, cutting the amount of fatty, salty and sweet foods.

Every summer a great many students travel to other countries looking for work and adventure. Most of the    26         are in seasonal work, mainly connected with wourism and    27         

The pay is usually poor, but most people work abroad for the     28     of travel. You can pick grapes on farms in France, entertain kids on American summer camps, and, of course, there are  29     jobs in hotels and restaurants.

   But it is not easy now to find work. “    30    you speak the language of the country well, there will be very few openings,” says Althea Ellis, an adviser in     31        for students.

“If you work with a family in Italy, you’ll have to speak Italian. When you wash dishes in a restaurant in Pairs, the owner will expect you to speak   32     . British students only have a language     33      for jobs in the USA and Australia.”

The pay was     39      and it really was a 24-hour-a-day job. The kids never slept!”

“The troubles is, students expect to have a(n)     40     time of it.” Althea Ellis points out. “After all, they see it as a    41      .In practice,     42       ,you have to work hard. At the same time, all vacation work is casual (临时的) work. You’ll have a job when the hotel, the restaurant, or the campsite is busy. In the other words, you’ll work if it’s convenient for the company that     43     you. But you have      44     employment rights.
