Teaching Procedures
I. Pre-reading Activities
A. Warm-up activities
a) Work in pairs to discuss the following questions to learn about the students’ understanding of iron deficiency
1) Do you like sports?
2) What do you usually eat or drink after doing exerci?
3) Do you feel tired after doing exerci?青岛好玩的
4) Do you think sports are always good to people’s health no matter how much they do it or when they do it?
5) What do you think is the best way to help women gain iron in their blood?
6) Do you think men also have the same problem of iron deficiency?
b) Work in groups to discuss the following questions.
1) Why do women often not have enough iron in their bodies?
2) If iron levels are low, what problems can women experience?
3) What can you eat to get iron and what disadvantages can the supplements sometimes have?
From our discussions, different conclusions can be drawn as follows:
1) Sports are always beneficial to people’s health. People of different ages usually do some exerci to build up their bodies. Some choo to run slowly on the playground, some climb mountains, some play all kinds of ball games, and some old people only walk slowly. No matter what they do, they feel merry-hearted and strong afterwards.
2) However, if people, specially the old, take too much exerci at some certain time, for instance, too early in the morning or too late at night, they feel exhausted and unable to sl
eep well. They even don’t have a very good appetite for anything the next day. Some young people even have to go to e a doctor after too much exerci beyond their expectation and stay away from school for some time following the doctor’s advice.
3) It’s necessary to help people get to know that moderate exerci is what they really need and that it’s important to supplement iron and other materials people need after doing exerci.
Thus lead into the text by saying: Although sports are necessary and important for people’s health, what people need is moderate exerci. Besides, it is important for people to remedy iron deficiency by eating something rich in iron or some iron supplements.
