　　T: How are you today?

　　Ss: Fine, thanks. And you?

　　T: Me, too. Did you have breakfast, S1?

　　S1: Yes.

　　T: I’m glad to hear that. Going to school withoutbreakfast is bad for your health. Health is

　　important for us.

　　2. (教師出示教學卡片或多媒體課件，復習上節(jié)課所學的有利于健康和不利于健康的生活習慣的表達方式。讓學生分出好與壞兩類，分組匯報。)

　　Step 2Presentation 第二步呈現(xiàn)(時間:10分鐘)

　　學習1a，引導學生根據(jù)語境猜測生詞的意思，培養(yǎng)學生整體閱讀的能力。

　　1. (繼續(xù)談論不健康的習慣會導致頭痛，并進行一項關(guān)于頭痛的調(diào)查，以此完成1a中導讀問題并呈現(xiàn)生詞。)

　　S4: I may have a headache.(引導學生回答。)

　　T: Please try to talk about the passage in your own words. You can look at the key words on the blackboard.

　　Example:

　　I know a headache isn’t a disease. There is something wrong with our health …

　　(及時鼓勵學生，增強學生信心。)

　　3. (完成1b，鞏固1a中重點短語。并核對答案。為2b的活動做鋪墊。)

　　T: Boys and girls, we talked about what causes headaches. As we know, headache isn’t a disease itself. But if we don’t have healthy living habits, germs can get into the human body and cause diseases. How do germs get into the human body? Let’s read2a and learn about it.
