Homework: a. learn the new words and expressions of the text by heart. b. go over the text and write down the difficult points. Step 2: Reading-Centred Activities (2 hours) Aim: global understanding of the text and active acquisition of the language points I. Global Reading Task: ◼ Talk about the main idea of the text in groups and answer the following questions (see exercise 2). ◼ The essay can be structurally divided into three parts. Part 1: This part consists of 3 paragraphs, from Paragraph 1 to Paragraph 3. The central topic is that exercise, even moderate exercise, may lead to reduced iron in the blood of women. Then three groups of people are mentioned as suffering from iron deficiency: endurance athletes, women starters of a program of moderate exercise showing evidence of iron loss and new exercisers with the normal diet showing a decrease in iron levels. Part 2: This part is made up of 3 paragraphs, from Paragraph 4 to Paragraph 6. Paragraph 4 tells us that iron deficiency is very common among women and the general causes for it. Paragraph 5 deals with one specific cause: the average woman takes in only two thirds of the recommended daily allowance for iron and any additional iron loss from exercise may be enough to tip her over the edge into a more serious deficiency. Paragraph 6 deals with another specific cause: exercise can result in iron loss through a variety of mechanisms. Part 3: This part is made up of 6 paragraphs, from Paragraph 7 to Paragraph 12. Paragraphs 7 and 8 tell us there are three stages of iron deficiency and that if you’re stage 3, it means your iron reserves go to zero and you’re in trouble. Paragraph 9 recommends one way to check the amount of iron storage in the blood. Paragraphs 10 to 12 suggest specific ways to correct iron deficiency in blood. Paragraph 10 is about adding more iron-rich foods to the diet, Paragraph 11 about selecting food with “iron-added” labels, cooking food in iron pans and avoiding coffee or tea with meals and Paragraph 12 about paying attention to warning signs of iron deficiency before iron reserves are gone.

Step Three: Study some key expressions in the passage and engage the Ssin their application. 1. .that endurance athletes, particularly females, frequently have iron deficiencies. (Para. 1) Meaning: .that athletes such as long distance runners, especially women athletes, often display a lack of iron. 2. Now a new study by a team of Purdue University researchers. (Para. 1) Meaning: Now a new study conducted by a team of researchers from Purdue University. 3. .suggests that even moderate exercise may lead to reduced iron in the blood of women. (Para. 1) Meaning: .suggests that even exercise of a mild type may cause a loss of iron in the blood of women. 4. We found that women who were normally inactive and then started a program of moderate exercise showed evidence of iron loss, . (Para. 2) Meaning: We found that women who were not in the habit of doing physical exercises but then suddenly began a program of exercise of middle degree showed signs of iron loss, . 5. Women who consumed additional meat or took iron supplements were able to bounce back,. (Para. 3) Meaning: Women who ate more meat than they usually did or took iron-added pills were able to return to their normal, healthy state,. 6.

(Para. 4) Meaning: . “too many women don't pay attention to how much iron they consume in food or drink”. 11. Women of child-bearing age are at greatest risk, since their monthly bleeding is a major source of iron loss. (Para. 4) Meaning: Women who are at the age of bearing children are put in greater danger of losing iron owing to their monthly bleeding. child-bearing age: The
normal span of women's production is between 18 and 50.with some exceptions.Women 12 women's physical phenomenon that occurs once a month,during which they bleed.The special term for that phenomenon is"menstruation' 13. Plus,many health-conscious women inerease their risk by rejecting red meat,.(Para. 4)Meaning:In addition,many women who care much about their health refuse to eat red meat such a as beef and mutton nd thus increase the danger iro As is pointed out and going to be further discussed,women generally suffer from iror deficiency,which is harmful to health.Now these women choose to give up red meat in their diet,so the lack of iron in their bodies is even greater,hence the increased risk.rejecting red meat:This is a mistaken idea of some health-conscious women.For health's sake,people need er these women wrongly believe that any es them fat and dum red meat:the meat of sheep (mutton)or fully-grown cows(beef) Compare: white meat 1)the very pale-coloured meat from th parts of acooked bird which are nicest toeat such the breast白肉（指煮好的家禽身上最好吃的部分，如鸡胸蒲） 2)certain types of pale-.coloured meat(veal and pork)白肉（小牛肉，猪肉） And because women often restrict their diet in an effort to control weight,they may not consume enough iron-rich food,and are liable to experience a deficiency.(Para.4) Meaning:And their food,they mayno uch ir and therefo iron than necessary 15.The average woman takes in only two thirds of the recommended daily allowance for iron,.(Para.5)Meaning:The average woman eats every day only two thirds of the necessary iron that health experts recommend. Based on investigation health exn erts can decide how much iron an should take in every day inorder tokeep fit.The fact is that many women dono ein the recommended amount,which puts them at the risk of iron deficiency. For a woman who already has a poor iron status.any additional iron loss from exercise may be enough to tip her over the edge into a more serious deficiency,.(Para.5) Meaning:Ifa woman who already has less iron than necessary starts a program of exercise hat causes more,then her iron status will change greatly and hell be put in more serious state of iron deficiency,. tip (sb.over the edge:bring about a noticeable change:(cause to)develop into another status 17.Exercise can result in iron loss through a variety of mechanisms.(Para.6)Meaning: Exercise can lead to iron loss because of the various functions of the body. Some iron is lost in sweat,and,for unknown reasons,intense enduran exercise is ometin sassociated with bleeding of the digestive system.(Para.6)Meaning:Some iror is lost when one sweats,and for the reasons unknown to us,intense endurance exercise may sometimes result in bleeding of the digestive system. digestive system:the whole length of the pipe down which food travels through the body while
5 normal span of women's production is between 18 and 50, with some exceptions. Women who are in that period are supposed to be able to give birth. 12. .since their monthly bleeding is a major source of iron loss. (Para. 4) monthly bleeding: women's physical phenomenon that occurs once a month, during which they bleed. The special term for that phenomenon is “menstruation”. 13. Plus, many health-conscious women increase their risk by rejecting red meat, . (Para. 4) Meaning: In addition, many women who care much about their health refuse to eat red meat such as beef and mutton and thus increase the danger of losing iron . As is pointed out and going to be further discussed, women generally suffer from iron deficiency, which is harmful to health. Now these women choose to give up red meat in their diet, so the lack of iron in their bodies is even greater, hence the increased risk. rejecting red meat: This is a mistaken idea of some health-conscious women. For health's sake, people need to take in red meat, which contains iron. However, these women wrongly believe that any meat, including red meat, can increase their weight, which makes them fat and dumb. red meat: the meat of sheep (mutton) or fully-grown cows (beef) Compare: white meat: 1)the very pale-coloured meat from those parts of a cooked bird which are nicest to eat, such as the breast of a chicken 白肉（指煮好的家禽身上最好吃的部分，如鸡胸脯） 2) certain types of pale-coloured meat (veal and pork) 白肉（小牛肉，猪肉） 14. And because women often restrict their diet in an effort to control weight, they may not consume enough iron-rich food, and are liable to experience a deficiency. (Para. 4) Meaning: And because women often limit their food, trying to control weight, they may not eat enough food containing much iron, and therefore are likely to have less iron than necessary. 15. The average woman takes in only two thirds of the recommended daily allowance for iron, . (Para. 5) Meaning: The average woman eats every day only two thirds of the necessary iron that health experts recommend, . Based on investigation, health experts can decide how much iron a woman should take in every day in order to keep fit. The fact is that many women do not take in the recommended amount, which puts them at the risk of iron deficiency. 16. For a woman who already has a poor iron status, any additional iron loss from exercise may be enough to tip her over the edge into a more serious deficiency, . (Para. 5) Meaning: If a woman who already has less iron than necessary starts a program of exercise that causes more loss of iron, then her iron status will change greatly and she'll be put in a more serious state of iron deficiency, . tip (sb.) over the edge: bring about a noticeable change; (cause to) develop into another status 17. Exercise can result in iron loss through a variety of mechanisms. (Para. 6) Meaning: Exercise can lead to iron loss because of the various functions of the body. 18. Some iron is lost in sweat, and, for unknown reasons, intense endurance exercise is sometimes associated with bleeding of the digestive system. (Para. 6) Meaning: Some iron is lost when one sweats, and for the reasons unknown to us, intense endurance exercise may sometimes result in bleeding of the digestive system. digestive system: the whole length of the pipe down which food travels through the body while
