       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.  71  

       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.   72   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.  73   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.  74   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.

          75   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".

       A small piece of fish each day may keep the heart doctor away.That's the finding of a scientific study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce(盎司)of salt water fish per day than those who never ate fish.

       The Dutch research is one of three human studies that hold the belief that eating fish can provide health benefits, particularly to the heart. Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring from heart attacks each year.But researchers previously have noticed that the incidence (发生率) of heart disease is lower in cultures that consume more fish than Americans do.There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption averages more than 3 ounces.

       For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish.

       At the start of the study, the average fish consumption was about two-thirds of an ounce each day with more men eating thin fish than fatty fish.

       During the next two decades, 78 of the men died from heart disease.The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos.This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol (胆固醇) levels.

 

64.Which of the following is NOT true according to the passage?

       A.The Dutch research has proved that eating fish can help to prevent heart disease.

       B.Heart doctors won't call at your house so long as you keep eating fish each day.

       C.Among all the diseases heart disease is the most dangerous in America.

       D.There is a low incidence of heart disease in Japan and Greenland.

65.The underlined phrase "this relationship" refers to the connection between ______and the incidence of heart disease.

       A.regular fish-eating                          B.the amount of fish eaten

       C.the kind of fish eaten                      D.people of different regions

66.The passage is mainly about ______.

       A.the high incidence of heart disease

       B.the great changes in people's diet

       C.the fish consumption in some countries

       D.the effect of fish eating on people 's health

67.How many lives could probably be saved each year in the United States by eating fish according to the Dutch study?

       A.152,000.         B.110,000.        C.275,000.        D.550,000.

       Introductory Chemistry was taught at Duke University for many years by Professor Bonk.One year, two guys took the class and did pretty well on all the quizzes and midterms.They each had a solid A.These two friends were so confident in going into the final that the weekend before the final week, despite the Chemistry final being on Monday, they decided to go to the University of Virginia to party with some friends.

       They had a great time there.However, with their hangovers (宿醉) and tiredness, they overslept all day Sunday and didn't make it back to Duke until early Monday morning.Rather than taking the final then, they found Professor Bonk after the final and explained to him how they missed the final.They told him they went up to the University of Virginia for the weekend and had planned to come back in time to study, but they had a flat tire on the way back and didn't have a spare.So they were late getting back to campus.

       Bonk thought this over and agreed that they could take the final the following day. The two guys, happy and relieved, studied that night and went in the next day at the time that Bonk had told them.He placed them in separate rooms and handed each of them a test booklet.He told them to begin.

      They looked at the first problem which was something simple about solution (溶解).It was worth 5 points."Cool," they thought, "this is going to be an easy final".

       They then turned the page.They were unprepared, however, for what they saw on it.

       The question contained only two words: (95 points) Which tire?
