Teaching plan I
I. Warming up
Step 1. In the first part Ss must first identify the kinds of foods shown in the photos and then consider they are healthy or not to eat. Some of the photos show what are called “food groups” because they are the same kinds of food. Others only show similar kinds of “junk food”.
Step 2. Have students choose partners who will ask them questions using the chart that is provided in the SB. In this way, they can practise their oral English doing an informal interview. The interviewer fills out the chart and then shows it to the interviewee to check it.
Step 3. After Ss have finished their charts, have some report to the whole class. Or make a class chart on the blackboard to find out which foods are most popular and when different kinds of foods are most often eaten.
II. Listening
Have Ss listen to the typescript carefully and then answer the questions.
Answers:
1 His left side huts.
2 No, he doesn’t. His temperature is normal.
3 Take some pills and call him if there is a problem.
III. Speaking
Step 1. In each situation, the patient is experiencing certain symptoms. Discuss this new word with students.
Step 2. A symptom is any physical problem that helps the doctor to determine the kind of illness a patient has. Sometimes different illnesses share the same symptoms. Ask the Ss to show this confusion in their dialogue.

Teaching plan II for Reading
I. Pre-reading
Step 1. Let Ss make a weekly log on a sheet of paper and mark the days of the week, meals of the day, and so forth.
Step 2. Then have them write in the times when they usually drink water, eat snacks, and have meals before they answer the questions.
Step 3. Encourage Ss to think critically in response to Question 1 and 2.
Answers to the exercises:
1 No correct answer.
2 Three meals is common but answers may vary. The second part requires self-reflection.
3 Water is consumed in different liquids. Encourage Ss to consider this fact in their responses.
4 In the “warming up”, the Ss had to consider what is and isn’t a snack. Their response to this question should reinforce, or add to, their understanding of just what a snack is.
II. Reading
Step 1. Tell Ss to read the text silently. Encourage them to read without use of a dictionary and try to get the main idea of each paragraph. For example, this paragraph talks about the importance of a good diet.
Step 2. Ss should then read the text a second time, paying more attention to details. When they find a word whose meaning isn’t clear, encourage them to look for context clues from the sentences. For example, what is the meaning of the word “functioning” in the second paragraph?
Step 3. Ask Ss to work with a partner, taking turns to read the paragraphs aloud. Have them ask questions of one another to see if both understand the basic themes of the text. For example, I think the author is telling us that we will lead a better life if we have a good diet.
Step 4. Finally, have the class read the text aloud and then discuss cause-effect relationships in it. For example, what will happen if we don’t make any plans for our diet?
