3、The food we eat seems to have a great effect on our health. Although science has made big 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 human illness is related to food and forty percent of cancer is related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized that things commonly used to keep colour in meats and other food additives（添加剂）caused cancer.

Yet, these additives remain in our food, and it is difficult to know which things on the wrappings（包装）of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar things are supplied to animals not for their health, but just to make a profit.

The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.

51. According to this passage, we can know      . 

  A. perhaps most of human illness is caused by what we eat

  B. perhaps most kinds of cancer are related to what people eat

  C. cancer was discovered in 1945

  D. science has made food unfit to eat

52. Things that are used to keep colours in meats are       .

53. All the additives       .

  B. are not bright and colourful

  C. have indirect effects on our health 

  D. have direct effects on our health

54. People use additives       .

  A. to make food more unfit to eat   

  B. to improve the colour and taste of the food

  C. to change colour of the food     

  D. to take off the diseases of the food

55. Which of the following is not true?

  A. Some wrappings of food are harmful.

  B. Farmers try to make more money on the market by fattening their animals.

  C. “The practice continues” means “things are still going on like that”.

  D. We needn’t take care of what we eat.

2、The easy way out isn't always easiest. I learned that lesson when I decided to treat Doug, my husband of one month, to a special meal. I glanced through my cookbook and chose a menu which included homemade bread. Knowing the bread would take time, I started on it as soon as Doug left for work. As I was not experienced in cooking, I thought if a dozen was good, two dozen would be better, so I doubled everything. As Doug loved oranges, I also opened a can of orange and poured it all into the bowl. Soon there was a sticky dough (面团) covered with ugly yellowish marks . Realizing I had been defeated, I put the dough in the rubbish bin outside so I wouldn't have to face Doug laughing at my work. I went on preparing the rest of the meal and, when Doug got home, we sat down to Cornish chicken with rice. He tried to enjoy the meal but seemed disturbed. Twice he got up and went outside, saying he thought he heard a noise. The third time he left, I went to the windows to see what he was doing. Looking out, I saw Doug standing about three feet from the rubbish bin, holding the lid up with a stick and looking into the container. When I came out of the house, he dropped the stick and explained that there was something alive in our rubbish bin. Picking up the stick again, he held the lid up enough for me to see. I felt cold. But I stepped closer and looked harder. Without doubt it was my work. The hot sun had caused the dough to double in size and the fermenting yeast (酵母) made the surface shake and sigh as though it were breathing . I had to admit what the "living thing" was and why it was there. I don't know who was more embarrassed by the whole thing--- Doug or me.
