Lei Yu writes his compositions in order.

1. The composition of the preface to Thunderstorm If a hot summer day is a book, Thunderstorm is its essence. It is like a wonderful hand of Dan Qing, pouring a lot of money into a dream world in one go; Like a black-faced judge, rain or shine is uncertain, and pieces of ink clouds are sprayed at will; If Zhang Fei is angry, the thunderbolt is amazing, which makes people feel that the sky is falling. Summer rain, although not as beautiful as morning mist and spectacular as sunset glow, has a kind of unrestrained and eclectic beauty.

In the summer afternoon, cicadas croak weakly in the branches, and even the black dog under the tree sticks out its tongue. After a while, the cicada died down, and I don't know when a gust of wind blew out of the window, which made the lonely tree tremble a few times and even the girl's temples were messy. Looking up at the window, there are dark clouds in the sky, which is so terrible and unique. That kind of ink seems to go from shallow to deep, especially in the center of the cloud, as if it were as black and shiny as a girl's braid. It's like someone's child knocked over the ink bottle, and it's like a painter's painting. The dark clouds are getting thicker and thicker, as if they are ready to go. There is no light in the sky, and it is getting dark. Even the distant scenery is hazy. Whether it's shiny headlights, soft street lamps or a few pedestrians, they are all hazy under the mist and all blend in with the dense fog. Brilliant white clouds seem to have been rendered by thick ink, which is really like Dongpo's famous sentence, "Dark clouds can't cover mountains with ink, but white rain jumps over boats." This time of summer, although a little more depressed, but a little more heroic.

Just like the dark clouds are getting thicker and thicker, that is, when they flash, the sky will be white and bright. Then it returned to the darkness. It's lightning Lightning parted the thick clouds, releasing dazzling light, surrounded by strange purple light. Like a huge demon, flashing greedy eyes; It is also like a poisonous snake, spitting its evil letter, and the aggressive beam makes people shudder. Bang, the thunder was like lightning, like a rock-breaking, and even the glass rattled, as if the world had committed a heinous crime, which provoked the jade emperor's great anger. The wind is getting stronger and stronger, mixed with dead leaves and dust, constantly beating the doors and windows, and even the temples of pedestrians are blown away, making it difficult to walk and looking flustered. Wind, thunder and electricity interweave into a symphony, making the sky dark and restless.

At this moment, a long-lost rainstorm finally arrived late, and the torrential rain flew down like a machine disaster relief, which was so sad and painful. At first, it was a ray of light rain like a silver needle, and at the biggest time, it was a white practice like a downpour. There seems to be dragons swimming in the rain, and there seems to be gods scattering silver scraps. Rain, through the coolness of summer, also explains the beauty of summer. After a while, the rain gradually became smaller, like cow hair,

Like a needle tip, it seems to be covered with a mist and a wisp of gauze in the distance. It is raining! Are you tired of dancing all day? Take a break!

Take a break! It rained less and less, and finally stopped quietly. ...

After the rain, the air is so fresh, the sky is so clear, and even the lake is so clear. Everything is so beautiful and harmonious. On the other side of the lake, a rainbow is woven in the sky. I pushed open the window and took a breath of fresh air. After the thunderstorm, it must be a rainbow!

Teaching reflection. Mr. Ye Shengtao said, "The author has a suspicion that when in Rome, do as the Romans do and begin to feel close."

If students want to have the perceptual experience described in the article, they must create a certain artistic conception and atmosphere, so that students can feel immersive. In this lesson, with the help of multimedia courseware, I try my best to let students intuitively perceive first, and then understand its meaning, so that students can see the same scenery as the author: hot summer, dark clouds, a thunderstorm before the thunderstorm, bringing a cool moment, breathing fresh air, enjoying the beautiful rainbow, hearing frogs croak in their ears ... It feels real, not fake, and is very impressive.

In addition, I attach importance to the understanding of key words, fully mobilize students' practical ability, oral ability and psychological ability, improve students' reading ability of sentences and words, and also improve students' reading interest and observation ability. "It is better to teach people to fish than to teach people to fish."

In teaching, I first lead students to perceive the text as a whole through silent reading and know the writing order and structure of the text; Then focus on leading students to learn the first part of thunderstorm (1-3 natural section), and through free reading, teacher's situational model reading, competition reading and synchronous reading, grasp key words to analyze feelings and imagine the artistic conception in reading. Then let the students learn the thunderstorm part (4-6 natural section) by imitating the previous part, and combine word learning with sentence reading through free reading and students' situational reading.

Finally, let go completely, and learn the part after the thunderstorm (7-8 natural section) with the previous method in group cooperation, aiming at cultivating students' self-study ability and group cooperation and inquiry ability. Taste the similarities of the text.
