"Cicada" PPT courseware

Part 1: Introduction to the author

Fabre, a world-famous entomologist, French. He was born in a poor peasant family and did not go to a decent primary school. In order to support his family, he had to work part-time. In the countryside, he was fascinated by the various insects in nature and fell in love with studying insects. Sometimes he would lie motionless on the ground for more than ten hours in a row, observing an insect in such detail that some people thought he was crazy. He attended normal school and worked as a primary and secondary school teacher.

He did not study entomology specifically, but relying on his dedicated self-study and long-term patient and meticulous observation and research, he spent most of his life and energy and wrote 10 volumes of "The Story of Insects" (also known as "The Story of Insects") based on detailed records of observations. Translated as "Insects").

After the publication of "The Story of Insects", Fabre became a world-famous writer of popular science books, familiar and loved by readers. His former residence and laboratory are now the Fabre Memorial Museum. Hugo called him "the Homer of the insect world."

This is a fascinating collection of popular science essays. It uses vivid and interesting writing to show people a colorful world of insects. "Cicada" is one of them. The text selects two parts of the article. The author wrote this article after carefully observing cicadas for 15 years. It can be seen that his academic attitude is very rigorous.

Fabre has a famous saying: "It doesn't matter whether someone teaches you or not. The most important thing is whether you have awareness." This is the secret of his success and will also give us great inspiration.

Cicada PPT, Part 4: Text Appreciation

As an explanation of things, "Cicada" is a scientific sketch. The explanation of cicadas in this article is neither a systematic and purely scientific explanation like that in general dictionaries and entomological works, nor is it expressed using literary methods like general scientific essays. "Cicada" is essentially a scientific observation note and investigation report, which belongs to the category of scientific works. However, the author uses some literary language to comprehensively introduce the scientific data describing the object, so it has some literary flavor. appears in:

For example, "Cicada's Egg" describes the hardships a "poor mother" goes through in giving birth to children, and also describes the hatefulness of a cicada that specializes in killing living creatures. The development of a cicada from an egg shows the hardship of the four-year long journey that the cicada goes through. In the last paragraph, "hard work", "pleasure", "singing", "wearing up", etc.

This gives the article a strong appeal, allowing readers to lament the growth of this little creature, and thus resonate with the author's argument and lyricism that "happiness is so hard-won yet so fleeting."

Using metaphors, scientific phenomena that are generally unknown are expressed in concrete images, and "performing a strange gymnastics" is used to compare the cicada's process of leaving the shell. Another example is to use accurate and vivid language to describe the observed situation. It is written that the cicada "solates in the air", "turns the body...stretches and spreads the wrinkled wings outward with all its strength,...uses the waist to try its best to lift the body." Turn it over, return to the normal position with the head up, hook its empty skin with your front paws, and then take the tail out of the sheath."

The entire action sequence has its own rules. The verbs such as "leap", "flip", "hang upside down", "stretch", "open", "turn", "hook" and "escape" are used very accurately, making the whole process of the cicada's shelling out. The process is accurately and vividly presented to the readers.
