Reading: the answer to the first person who invented anesthesia

12, the first person to invent anesthetic.

Teaching material analysis:

It is described that 1700 years ago, Hua Tuo, a famous Chinese doctor, developed Mafeisan to relieve the pain of surgical patients and became the first person to invent anesthetic in the world, which made us know that China's ancient science and technology was in the leading position in the world and made us proud of China's splendid ancient science and culture. The first section briefly introduces Hua Tuo as a doctor with superb medical skills, and the second to seventh sections describe two impressive things in the process of practicing medicine in detail. It was these two things that triggered Hua Tuo's thinking. Finally, he invented the anesthetic, which reflected Hua Tuo's thoughts and feelings of being considerate and anxious for patients. In the meantime, he grasped what Hua Tuo saw, heard and thought during his second operation, and the article was clear and focused.

A. Read the relevant content silently and tell the whole thing in one or two sentences.

When Hua Tuo operated on him, he was not struggling and moaning, but limping and being at the mercy of others. After the successful completion of the operation, he was still snoring drowsily, and there was no pain at all.

* Read the sentences. What did you read about drunkards at this moment?

Please come back to see the child's operation.

Show a scene of a child's operation: once, a child had a poisonous sore on his arm and needed to cut off rotten meat. Hua tuo operated on him, and the child jumped with pain and cried like a heartbroken person.

Transition from teacher to teacher: the two situations are completely different. Not only does the drunk not feel the pain like a child, but he doesn't need to successfully complete his or her operation. At this time, if you are present, you will feel that Hua Tuo has a lot of feelings, so ask the person behind his back what kind of dialogue will happen between them. Please send two students from each group to talk about it. One is Hua Tuo, the other is Hua Tuo.

(Group practice, large group communication)

Transition from teacher to teacher: Hua Tuo listened to the words of the person who lifted people and looked at the drunk in front of him thoughtfully: if there is a medicine that patients can take, it is like being drunk. Isn't the operation painless? (reading sentences)

Teacher's transition: rhetorical questions are used in the book to express his strong desire to have this medicine, which makes us realize the excitement and excitement when he was deeply uneasy before, but now it seems that there is a feeling that "there is no way to recover from the mountains and rivers, and a village is bright in the dark." If you say this in another form, what is the difference from the original sentence?

Looking at the drunk, Hua Tuo mused: If a medicine is given to the patient, it will be like being drunk, and the operation will not be painful.

Looking at the drunk, Hua tuo mused: if there is medicine, the patient will feel drunk, then the operation will not be painful.

2. Teacher: Today, we approached Hua Tuo, and got to know Hua Tuo, who is "anxious about the patient's urgency, thinking about the patient's thoughts" and "good at observing and thinking". From today's learning process, I found that the students in our class are also good at thinking and thinking. This attitude towards learning is really good, and I hope it can be maintained.
