Text More than 200 years ago, there was a French physicist named Ampere, who was very absorbed in scientific research. One day, Ampere was walking in the street. The streets are full of pedestrians and vehicles. But Ampere didn't seem to see or hear anything, just walked on with his head down. It turned out that he was thinking about a math problem.
At first, he was doing mental arithmetic and drawing on the skirt with his fingers. Later, he felt that he needed to find a place to do it. Coincidentally, a "blackboard" stood beside the street, as if it were specially prepared for him. Great! Ampere walked over happily, took out chalk from his pocket and calculated it on the blackboard.
Counting, this "blackboard" is moving slowly and moving forward. Ampere quickly said, "Don't move, don't move, wait a little longer and we'll get the result!" " "However, the blackboard is still moving forward, and Ampere can't help but follow the blackboard and continue to concentrate on calculation.
Later, the "blackboard" went faster and faster, and Ampere felt that he could not catch up. Only then did he realize that it was not a blackboard, but the back wall of a carriage.
teaching program
Teaching requirements: 1 Learn to read the text silently and tell stories in an orderly way.

Reading the text for the first time can read it correctly and fluently; Learn to read silently (moving your mouth without moving your voice); Starting with the math exam.
Teaching process:
Introduce a new course
1 blackboard book: 14 "blackboard" ran away.
Students read the topic together.
The blackboard has no feet, how can it run by itself? Please read the text by yourselves.
Second, read the text for the first time and understand it initially.
1 self-reading
Requirements: Correct pronunciation, complete sentences, and mark the text with natural paragraphs.
2 check
Ampere physicists focus on scientific research.
Thinking, calculation, calculus, vertical chalk
Move out of the starting performance car.
Busy, ready to continue, traffic only.
Read by name, read by train and read together.
3 Students read the text silently
Do it: move your eyes (pinyin and words are two lines), use your head, and keep your voice still. (Teacher checks)
Read the full text by name in Section 4.
Read the text together. Thinking: What did you read?
6 discuss communication
Third, learn new words: from the math test.
1 Read the new words together and analyze the glyphs.
2 Teachers demonstrate writing. Students complete the "word book".
Second lesson
Teaching requirements:
Learn the text around "Ampere is very attentive to scientific research" and guide students to read aloud.
Teaching process:
View and import
Last class, we knew whose story the text was about.
Writing on the blackboard: Ampere
Discuss and understand the text.
The text introduces ampere in one sentence. Please find it and read it.
1 Learn the first paragraph
(1) Students can read freely.
(2) Read by name
(3) How to read this sentence well?
(4) Surrounding lens: French physicist
Pay great attention to scientific research
This paper gives an example to illustrate that Ampere is very attentive to scientific research. what's up
Discussion;
Yes, Ampere mistook the back wall of the carriage for a blackboard. Therefore, the subject blackboard ran away, but it actually ran away. So the title is quoted. Used to indicate that it is not a real blackboard, but the back wall of a carriage. It is conceivable that Ampere is very devoted to scientific research.
Which sentences in the text can show that Ampere is really devoted to scientific research?
2 Learn 2-5 paragraphs.
Discuss in groups, find out the sentences and read them. (In the second to fifth paragraphs of the text)
Talk and discuss in class and guide reading at will.
Ampere's concentration, to use an idiom in the article, is called concentration.
Teacher Lu also gave everyone an idiom: concentration.
Third, summarize the full text.
1 Read the text with emotion.
What do you want to say after learning the text?
The third category
Teaching requirements:
Learn new words: prepare powder and adjust essence; Practice telling stories; Finish the exercise.
Teaching process:
Instruct storytelling
1 Read at the same time
2 show the outline:
Introduce ampere
It is clear that Ampere is very absorbed in scientific research, so how can he mistake the back wall of the carriage for a blackboard?
Talk to each other at the same table
