Pre-reading activites
1. Background Information
1) Medicine
c. The new exercisers who followed their normal diet showed a decrease in iron levels. (Para. 3)
(3) Analysis of general causes for it: (Para. 4)
a. Too many women ignore the amount of iron they take in;
b. Women’s monthly bleeding is a major source of iron loss;
c. Many women increase their risk of iron loss by rejecting red meat;
d. Women are liable to experience a deficiency as a result of restricting their diet in weight control.
(4) Analysis of specific causes for it: (Paras. 5 - 6)
a. The average woman takes in only 2/3 of the recommended daily allowance for iron, which would easily cause iron deficiency if they take some exercises. (Para. 5)
b. Some iron is lost in sweat, and intense endurance exercises may cause iron deficiency through bleeding of the digestive system and bleeding of the blood vessels in the feet. (Para. 6)
(5) Analysis of effects of iron deficiency: (Paras. 7 - 8)
a. Fatigue and poor performance may begin to appear when not enough iron is present in their blood to form the molecules of blood protein that transport oxygen to the working muscles.
b. When their iron reserves go to zero, people often feel weak, tired, and out of breath — and their exercise performance is severely compromised; and they are in trouble.
(6) Analysis of effects of iron deficiency: (Paras. 7 - 8)
a. Fatigue and poor performance may begin to appear when not enough iron is present in their blood to form the molecules of blood protein that transport oxygen to the working muscles.
b. When their iron reserves go to zero, people often feel weak, tired, and out of breath — and their exercise performance is severely compromised; and they are in trouble.
(7) Analysis of importance of checking iron reserves: (Para. 9)
a. It is important to check levels of a different compound, which indicates the amount of storage of iron in the blood.
b. Both women and men are at risk of iron deficiency as a result of a high level of active physical exercise.
c. It is advisable for people in these groups to have a yearly blood test to check blood iron reserves.
(8).Solution to the problem: (Paras. 10 - 11)
a. If iron levels are low, talk with a physician to see if the deficiency should be corrected by modifying your diet or by taking supplements… (Para. 10)
b. Select breads and cereals with the words ‘iron-added’ on the label… (Para. 11)
c. Eat the foods with plentiful Vitamin C to enhance the amount of iron absorbed. (Para. 11)
d. Cook in iron pans, as food can derive iron from the pan during the cooking process. ( Para. 11)
e. Avoid drinking coffee or tea with meals, since substances in these drinks can interfere with iron being absorbed into the body. ( Para. 11)
(9).Evaluation: (Para. 12)
“Active women need to be a lot more careful about their food choices. If you pay attention to warning signs before iron reserves are gone, you can remedy the deficiency before it really becomes a problem.” To support his argument, the author quotes as hard evidence the remarks respectively from the associate professor of Purdue University, Roseanne M. Lyle (Paras. 2, 3 and 12), another expert at Purdue (Para. 5), one of the Purdue study designers, John L. Beard (Paras. 8 and 9), and the sports diet expert Nancy Clark (Para. 11).

Post-reading: discussion: .
1 What do you think the effects of exercise are?
Just as every coin has two sides, exercise can also bring us harm as well as benefits. If you are normally inactive and then, prompted by a sudden impulse, start a big program of intense exercise, there are more chances that you have yourself injured. In addition, as for those who go on a fat-reducing diet, the more exercise they take, the greater loss of iron they will suffer and the worse their health conditions will get. And worst of all, continual as well as excessive exercise is more likely to result in sudden death. Thus, how to go in for exercise is something worth more of our concern.
2. What advice can you give on physical exercise?
Here are the insights gleaned from my own experience in physical exercise: 1) Before you take any physical exercise, you must have a clear idea about what kind of exercise is good for your health as well as suitable to your own physical conditions. 2) Once you start your program of exercise, both progressiveness and regularity become two key ingredients in your smooth implementation of the program. 3) With the amount of your exercise on a gradual increase, you should add more iron-rich foods to your daily diet.

Does Exercise Have Unexpected Benefits?

Teaching Objectives:
Ss should be able to :
1) grasp the reading skill
2) grasp the main idea of the text
2) grasp the language points

Reading Skills: Distinguishing Between Facts & Opinions
Facts are statements that tell what really happened or what really is the case. A fact can be proved or disproved with direct evidence. It is something known by actual experience or observation..
Opinions are statements of belief, judgment or feeling. They show what someone thinks or feels about a subject. Solid opinions, of course, are based on facts. However, opinions are still somebody’s view of something and are not facts themselves.

Do exercise XV on Page 54 to practice distinguishing facts and opinions.

Global Reading:
1. structure: general statement + examples
2. Main idea: physical exercise has positive effect on mental functioning
1) rats study
2) human study (older adults and children)
