35. Unit 6 Dialogue I Discovery Vitamin A Vitamin B part 1 Vitamin B part 2 Vitamin C Vitamin D Vitamin K Suggestion VOA Vitamins

36. Unit 6 The word vitamin dates back to Polish scientist Casimir Funk in nineteen twelve. He was studying a substance in the hull that covers rice. This substance was believed to cure a disorder called beriberi. Funk believed the substance belonged to a group of chemicals known as amines [uh-MEENS]. He added the Latin word "vita," meaning life. So he called the substance a "vitamine" [vita- MEEN] -- an amine necessary for life. Funk was not able to separate the anti-berberi substance from the rice hulls; it was later shown to be thiamine. Other studies found that not all vitamines were amines after all. So the name was shortened to vitamin. But Funk was correct in recognizing their importance. Scientists have discovered fourteen kinds of vitamins. They are known as vitamins A, the B group, C, D, E and K.

37. Unit 6 Which foods should be eaten to keep us healthy? Let us look at some important vitamins for these answers. Vitamin A helps prevent skin and other tissues from becoming dry. It is also needed to make a light-sensitive substance in the eyes. People who do not get enough vitamin A cannot see well in darkness. They may develop a condition that dries the eyes. This can result in infections and lead to blindness. Vitamin A is found in fish liver oil. It also is in the yellow part of eggs. Sweet potatoes, carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A.

38. Unit 6 Vitamin B-one is also called thiamine. Thiamine changes starchy foods into energy. It also helps the heart and nervous system work smoothly. Without it, we would be weak and would not grow. We also might develop beriberi. Thiamine is found not just in whole grains like brown rice, but also in other foods. These include beans and peas, nuts, and meat and fish.

39. Unit 6 Another B-vitamin is niacin ( 烟酸 ). It helps cells use food energy. It also prevents pellagra -- a disease that causes weakness, reddish skin and stomach problems. Niacin is found in meat, fish and green vegetables. Vitamin B-twelve is needed so folic acid （叶酸） can do its work. Together, they help produce red blood cells. Vitamin B- twelve is found naturally in foods such as eggs, meat, fish and milk products. Folic acid has been shown to prevent physical problems in babies when taken by their mothers during pregnancy. Vitamin B-twelve is found in green leafy vegetables and other foods, like legumes （豆球蛋白） and citrus fruits. In some countries, it is added to products like bread.

40. Unit 6 Vitamin C is needed for strong bones and teeth, and for healthy blood passages. It also helps wounds heal quickly. The body stores little vitamin C. So we must get it every day in foods such as citrus fruits, tomatoes and uncooked cabbage.

41. Unit 6 Vitamin D increases levels of the element calcium （钙） in the blood. Calcium is needed for nerve and muscle cells to work normally. It also is needed to build strong bones. Vitamin D prevents the children's bone disease rickets. Ultraviolet light from the sun changes a substance in the skin into vitamin D. Fish liver oil also contains vitamin D. In some countries, milk producers add vitamin D to milk so children will get enough.

42. Unit 6 Vitamin K is needed for healthy blood. It thickens the blood around a cut to stop bleeding. Bacteria in the intestines （肠） normally produce vitamin K. It can also be found in pork products, liver and in vegetables like cabbage, kale （甘蓝） and spinach （菠菜）.

43. Unit 6 Language Points Our bodies manufacture some vitamins To make or process (a raw material) into a finished product, especially by means of a large-scale industrial operation. 制 造：（把原材料）制造加工或成品，尤指大型工业的运 作 it is contrasted with raw materials, hand-made goods 区别于原 料、手工制品 ---manufacture shoes ---manufacturing Industry 制造工业 ---goods of foreign manufacture ( n. ) 外国产品 ---firms engaged in the manufacture of plastics ( n. ) 从事制造塑 胶的企业 1 Reading I

50. Unit 6 Guided Writing I do not quite recall what my grandma was like as she died when I was not yet ten. I only know that she was quite a scholar. The impression she left me was that of a frail, pale and smiling old lady. However, there is one thing that I remember very well. She always ate sparingly, and no meat at all, not even milk or eggs, which always surprised me. She was a vegetarian, my father told me, and a very thorough one, too. The result was disastrous, she was highly weakened by not absorbing proteins, the body-building elements, which are found much more abundantly in animal meat, milk and eggs than in vegetables. It is evident that without meat, milk and eggs, a human being cannot live a full and active life. It was really a pity that my grandma chose to be a vegetarian, otherwise I would have learned more of her and from her. Exercise 1

55. Unit 6 There are three main kinds of food. Sugar and starch are grouped together as carbohydrates: they are found in bread, potatoes and rice. These are mainly energy-giving food which the muscles and other tissues use. Fats are also energy-giving foods but do no give it as quickly as the sugars and starches as they have to be broken up in the liver and made into sugar before they can be burnt by the body. The other class known as proteins are the main solid part in all living cells. They are found in milk, meat and fish, and are necessary to the body to enable it to build new cells and repair old ones. For this reason growing children need more proteins than adults. Children are much more active than adults and use more energy for their size they need a lot of energy-giving foods, the carbohydrates. Children cannot get much of their energy from fat because it makes them unwell if they eat too much of it. A specially fine thing about the body is that it uses the things you like better than the things you do not like, so giving truth to the old saying “A little of what you fancy does you good."

One solution is that we should have smaller families and lower the birth rate. Many nations have plans to limit their population. Another solution is that we should improve our food supply.

61. Unit 6 China has long been looked upon as a land of many famous craftsmen whose artistic works are treasured to this day. The most famous of all was a man called Lu Ban. He lived many centuries ago, but people still remember the marvellous houses and palaces he planned and built even though the buildings themselves have long since disappeared. Lu Ban’ skill was so great that people even used to wonder if he was an immortal. Although it is a long time since Lu Ban left this world, old men in Beijing say that Lu still has the welfare of all craftsmen in his heart. Whenever craftsmen find themselves in difficulty, they pray to Lu Ban for help. There are many stories in Beijing about the occasions on which Lu Ban gave his help to ordinary craftsmen.

67. With the development of society, many people can afford a car. As the number of the cars is rising, we are facing some problems. One big problem is the pollution caused by the use of cars. In order to solve this problem, government agencies in some big cities recently suggest that a “pollution tax” should be put on private cars in order to control the number of cars and reduce pollution in the city. For my part, I agree to this viewpoint, and my reasons are as follows:

68. Unit 6 To begin with, cars contribute to the environmental pollution. …. Secondly, it is a good way to raise people’s environmental awareness by putting a pollution tax on private cars. … In a word, it is a very good and necessary attempt to use the means of taxation to treat the pollution. Of course, it must be kept in mind that all people, including the private car owners, should try their best to protect the environment.
