What are Verne's trilogy written about? Pray for the great gods.

The story of Captain Grant's children took place in 1864. Sir greiner Wan, a Scottish aristocrat, is the owner of the cruise ship Duncan. He obtained a document from the drifting objects at sea, from which he learned that Captain Grant, a Scottish navigator who was killed and disappeared at sea two years ago, was still alive, so he resolutely took the captain's daughter Mary and son Robert and others to drive his own cruise ship to find and rescue. After they arrived in South America, they crossed the American continent and finally found that the captain was killed on the Australian coast. After they arrived in Australia by boat, they met Elton, the captain's original sailor, who was taken in by the pirate leader and crossed the Australian mainland. After being captured by the natives, he was in a desperate situation. After they escaped, they decided to abandon Elton on the desolate island of tabor in the Pacific Ocean. Unexpectedly, they met Captain Grant on the island, so they successfully returned to Scotland together. The book also describes people's adventures in nature, including earthquakes, hurricanes and wolves; Hundreds of cows fell into the mire together, and the raging flood turned the plain into an ocean; Some of them fled from trees hit by lightning and met crocodiles lurking in the water; It's really dangerous and exciting. What is even more touching is that Captain Grant sacrificed himself in the Pacific Ocean to find an immigrant island for Scottish expatriates in order to oppose English slavery to Scotland, while Sir Granawan spared no effort to save his compatriots. They are brave, tenacious and fearless, which embodies Verne's progressive thought of opposing slavery and colonialism, and shows the noble quality and lofty humanitarian spirit of maintaining social justice. This is a passionate and mysterious story. Is the mysterious drift bottle in the belly of the "balance fish" (an extremely fierce shark in the sea) found by Sir Griffin a distress letter from a wrecked ship or a limerick written by a sailor when he is bored? It is a letter! It is a distress letter written in English, French and German in three chapters. These three distress letters damaged by seawater aroused great exploration interest of navigators. They translated the clear words in the letter and then compiled them into a language. They filled in their own guesses and ideas in this distress letter. Yes, it is indeed a distress letter! This is Captain Grant's distress letter. He was arrested by Indians at 37. 1 1' north latitude. The witty Sir Griffin, the kind and gentle Lady Helen, the deep and steady Major Mike Nabbes, the careless but proficient geographer Baganel, and the two strong sons and daughters of Captain Grant: the determined and strong Miss Grant and the brave little Andrew Roble, Captain mengle, who is proficient in navigation, and the completely trustworthy old sailor Austin. They set out on the Duncan to rescue Captain Grant ...> The story is not complicated: it happened in 1866, and Pierre Aronnax, a Frenchman, a biologist, was invited to participate in a scientific investigation in the United States. There was a monster at sea at that time, which caused an uproar all over the world. After the expedition, the biologist was preparing to pack his bags and return to France, but he was invited by the United States Admiralty, so he changed his course and boarded a destroyer to participate in the activity of "removing that monster from the ocean". After many hardships, the "monster" has not been removed, but the destroyer has been hit hard by the "monster". The naturalist, his servant and a whaling ship specially invited to the destroyer to get rid of the monster have all become prisoners of the monster! That "monster" is not him. It turned out to be an unknown submarine named Nautilus. Submarines also give preferential treatment to prisoners; However, in order to keep his secret, the submarine captain Nemo never allowed them to leave. Pierre Aronnax and his team had no choice but to follow the submarine around the ocean. 10 months later, the three men finally escaped under extremely dangerous circumstances, and biologists were able to make this underwater secret public. "Two Wan Li under the Sea" is mainly about their ten-month experience. There have been many Chinese versions of Two Wan Li under the Sea, and "Two Wan Li" has become a conventional saying. In fact, the "Li" here refers to Guri in France, which is divided into land and sea, with an ancient sea of about 5.556 kilometers and an ancient land of about 4.445 kilometers; Since it's an undersea tour, the two Wan Li here should be 20,000 nautical miles. In this way, the distance they traveled on the seabed should exceed 1 1 10,000 kilometers. This is to be explained. 1 1 10,000 km journey is a big scene, and what you see along the way can be said to be full of wonders. Who has seen the undersea forest? Who has seen a submarine coal mine? Who has ever seen priceless pearls "raised" in shells? Arona Cox, a prisoner, and his friends met him and once wandered around. They fought with sharks in the pearl farm in the Indian Ocean, and the whaling ship Ned Land cut down a fierce giant shark. They hunted an endangered dugong in the Red Sea, and the meat of the dugong was served on the table that night. They fought a bloody battle with octopus in the Atlantic Ocean, and a crew member died tragically. These scenes are very thrilling. In addition, the book also describes how sperm whales kill fin whales and how the submarine Nautilus kills groups of sperm whales, which is also very rare. Pierre Aronnax is a biologist, knowledgeable, knowledgeable, sailing underwater by submarine, so that he can appreciate all kinds of animals and plants in the ocean; He and Conseil, a servant fascinated by taxonomy, gave us a detailed introduction to these marine life, describing the world, phylum, class, order, family, genus and species in an orderly way, which made readers know many marine life. Arona has also seen various wonders in the ocean, one after another, which has opened readers' eyes, knowing what is the Pacific Black Current, what is the Mexican Warm Current, how hurricanes are formed, and what is the the sargasso sea ... Do we know how coral reefs are formed? Do you know how deep the ocean is? Do you know how fast the ocean travels sound? This kind of knowledge can be found everywhere in books. Nautilus was also in distress, lying too shallow on the coral reef and being attacked by Papua aborigines. The most terrible thing is that people on board can hardly survive because they are trapped by thick ice at the South Pole. However, with the excellent structure of the submarine and the captain's superhuman wisdom, all kinds of dangers were resolved, and finally the submarine trip of 1 1 10,000 kilometers was completed. In Verne's time, the submarine just appeared and was still a mysterious thing; Nemo, the captain of the Nautilus, is a man of unknown origin. He escaped from human beings and lived in seclusion at the bottom of the sea, but vaguely had a special connection with some people on land. All these add a layer of mystery to the novel. Since it is a novel, the characters are of course fictional. The Latin name given by the author to Captain Nautilus clearly points out this point-"Nemo" has no meaning in Latin. But this does not prevent the author from describing him as a flesh-and-blood figure, which makes readers feel credible. ◆ Story Introduction ◆ 1889, in Paris, a teenager who likes to invent in the World Expo venues met Nadia, a girl with a little lion.
