The food we eat seems to have far-reaching effects on our health. Although science has made great steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially the colon(结肠)cancer. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, government researchers realized that carcinogenic(致癌的)nitrates(硝酸盐)commonly used to preserve color in meats and other food additives(添加剂), caused cancer. Yet, these additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives, which we eat, are not all so direct. Farmers often give penicillin(青霉素)to cows and other living animals, and because of this, penicillin has been found in the milk of treated cows. Sometime, similar drugs are given to animals not for medical purposes, but for financial reason. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration has tried repeatedly to control these procedures, the practices continue.

1.     What is the best possible title of the passage?

A. Drugs and Health        B. Food and Illness

C. Food and Culture        D. Health and Science

2.     Which of the following statements is NOT true?

a)     Drugs are always given to animals for medical reasons.

b)      Some of the additives in our food are added directly to the food and some are given to living animals.

c)      Researchers have realized the possible dangers of food additives for over fifty years.

d)      Food may cause 40% of cancer in the world.

3.     How has science done something harmful to mankind?

a)     Because of science, diseases caused by contaminated(被污染的) food have been actually reduced.

b)      It has caused a lack of information concerning the food.

c)      Due to the application of science, some potentially harmful substances have been added to food.

d)      It causes the animals to become fatter.

4.     The government tries to _______.

a)     control the market price of food.

b)      stop the farmers from giving drugs to animals to make more money.

  LONDON(Reuters)-Ecotourism(生态旅游)is causing a lot of damage to wildlife and may be endangering the survial(生存)of the very animals people are flocking to see, according to researchers.

  Biologists and conservationists(自然环境保护论者)are worried because polar bears, dolphins, penguins and other creatures are getting stressed and losing weight and some are dying.

  Evidence(证据)is growing that many animals do not react well to tourists in their backyard.”New Scientist magazine said.

  The immediate effects researchers have noticed are changes in behavior, heart rates, or stress hormone levels but they fear it could get much worse and over the long term“could endanger the survival of the very wildlife they want to see”.

  Although money produced through ecotourism, which has been growing at about 10~30 percent a year, has major benefits for poor countries and people living in rural areas, the Swiss-based World Conservation Union and some governments fear not all projects are audited(审计)and based on environmentally friendly policies, according to the magazine.

  “The transmission(传播)of disease to wildlife, or small changes to wildlife health through disturbance of daily life or increased stress levels, while not obvious to the casual observer, may translate to lower survival and breeding.”said Philip Seddon, of the University of Otago in Dunedin, New Zealand.

  Scientists have noticed that bottleneck dolphins along the nortbeastem coast of New Zealand become nervously excited when tourist boats arrive, Similar changes in behavior have been observed in polar bears and yellow- eyed penguins in areas visited by ecotourists are producing smaller babies.

  Conservationists are now calling for more research into the effect of ecotourism on animals and say the industry must be developed carefully.They also want studies done before new ecotourism projects are started.

  “The animal's welfare should be very important because without them there will be no ecotourism.”said Rochelle Constantine of the University of Auckland in New Zealand.
