[Multimedia display litchi close-up]
Everyone must have seen this bright and attractive fruit on the screen. It is called the king of fruit. It's called-(Student Qi Answer: Litchi).
Please look at the pictures carefully and talk about litchi in your eyes with your own life experience. You can also introduce litchi to people who have never seen it, or recommend litchi to people who have never tasted it. (Inviting students to speak)
Today, we are going to learn the first article in the Science Fair unit: Mr. Jia Zuzhang's scientific sketch "Zhou Nan June Litchi Dan" to see how he introduced Litchi.
Two. Brief introduction of the author
Jia Zuzhang is a famous biologist and popular science writer in China. The name Jia Zuzhang may not be familiar to everyone, but his hometown must be familiar to everyone. This place is Haining. 190 1 was born in Huangwan, Haining, China (any students in Huangwan here, especially those celebrities in your hometown, should be proud. Of course, everyone in Haining should be proud of Teacher Jia).
As early as the 1920s, he compiled more than 600,000-word monographs such as Botanical Illustration of China, and his Introduction to Birds published by the Commercial Press in 193 1 was the earliest modern bird book in China. In addition, he also created a large number of popular science works, including birds and literature, animal stories, sketches of life, and broken brocade of biology. Our text "Litchi Dan in Zhou Nan in June" is selected from the book "Biology Broken Brocade". Most of these works are written with colorful creatures, which are rich in scientific knowledge, historical knowledge and literary knowledge, and are quite ideological, scientific and artistic.
Third, the pronunciation of words.
Let's write down the underlined words together and see the preview effect.
Red cheese, purple cheese, xiāo, zēng buttermilk.

Fourth, emphasize the importance of quoting this interpretation method.
Explanatory writing is a style that everyone has been exposed to before, such as Stone Arch Bridge in China, Soybean in the Motherland and Bamboo in the Midwinter in junior middle school. Please use one or two words to express your most intuitive feelings about this style. (Plain, clear, knowledgeable, monotonous, boring and dry)
Then, please look at our text. Do you feel dry, too (I don't think so)
Of course, this is also an explanatory article, but why can it give us a refreshing feeling? Who can tell me why? In other words, what method does the article take to change the monotonous state of explanatory words?
(quoting a lot of poetic allusions)
We have learned many ways to explain, but we count with our fingers. What explanations have we learned? Examples; Metaphor (metaphor); Make a comparison (contrast); Quotation (quotation); Column number; Definition; Classification. Citation is one of them. In our text, it is unique and shines brilliantly.
Ask the students to find all the poems and allusions quoted by the author from the text and underline them with horizontal or wavy lines. (about 2 minutes)
There are about twelve places altogether. Let's analyze and discuss their functions and aesthetics together.
Fifth, analyze the meaning of the text from the function of the quotation.
1. When I was a child, I questioned Bai Juyi's Preface to Litchi: the shell is like a red dragonfly, the membrane is like purple gauze, the meat is like Bai Rubing snow, and the pulp is like cheese.
[Projecting dried litchi, peeling on the spot]
Function: Introduce topics, be friendly and lively, and conform to reading psychology. The original quotation provides a basis for the following different views.
2. Practice form: Many ancient poems and sentences are quoted to illustrate the knowledge about litchi. Try to point out the specific objects of the following quotations. [See Courseware]
Point out the object of interpretation by looking at the picture and the original text. And then summarize the general idea of the natural paragraph where the quoted text is located. Knowing the usage of quotation, the focus of this natural paragraph will naturally appear in front of us.
3. The role of citation
These quotations are authentic and full of charm, adding bright colors to the monotonous expository writing and becoming vivid literature and art.
Students read the text quickly, filter the key information of each paragraph and summarize the meaning of the paragraph.
Next, please read the full text quickly and filter the key information of each paragraph. Some have been analyzed with the reference function just now, and some have not been analyzed, but the information points are also obvious. Please summarize the general idea of each paragraph with a word or phrase, string it into a straight line with "-"and write it on the white paper prepared before class. Write carefully and write bigger.
Please raise your hand for the first student to finish the task. After the three students with the shortest duration are decided, we will project their reading scores, and the students will judge a "reading expert". He will get a batch of dried litchi sponsored by his teacher and me.

2. Show the structural diagram summarized by the teacher. [See Courseware]
3. Focus on inspection and consolidation: Look at the picture (litchi fruit) and point out the names of each part.
Seven, in-class exercises
