Liu Xian, a native of Nanchang, was born with a big figure and unparalleled physical strength. When he was young, his family was poor and he made a living as a helper. Catch up with the famine, he couldn't stand hunger and pain because of overeating, so he had the idea of suicide. He went to an abandoned shrine to hang himself, but he didn't want to hang himself twice in a row. They all failed because the rope and rafters were broken. Liu Xian thought there was a man of God to protect him, so he left and mourned. He hung out among a group of porters and worked as a servant. After a year, he went to Sichuan, a land of abundance, lived in a temple, and lived by working for a short time and stealing offerings from the temple. He locked the stolen offering in a big clock and it took him a long time to be found. His magical physical strength is regarded as heaven and earth. In the thirty-fourth year of Jiajing, the Miao people in Yibin, southern Sichuan, rebelled, and Governor Zhang Hao recruited soldiers to counter the rebellion. Under the persuasion of all, Liu Xian was drafted into the army. In the first battle, he took the lead in dancing two big hay cutters, personally cut down 50 or 60 people and captured three thieves. After the army advanced, the rebellion was wiped out in one fell swoop, and Liu Xian became famous from a pawn to a deputy thousand households. After that, he went to the battlefield and was promoted to company commander for seven years. His rapid promotion is rare among military commanders in past dynasties.

2. dinosaurs are everywhere. read the answer. dinosaurs are everywhere. dinosaurs are everywhere. At first glance, we may think that this short article is describing the prosperity of dinosaur families around the world, but after reading the whole article, we know that this is a popular science paper that proves the theory of "plate structure" through the discovery of Antarctic dinosaur fossils.
There is a sudden discussion at the beginning of the article: "Different scientific fields are closely linked. New discoveries in one scientific field will certainly have an impact on other fields. "
These two comments are the logical basis of the whole article. There are dinosaur fossils on all continents such as Antarctica, "indicating that dinosaurs are indeed all over the world".
In particular, the discovery of Antarctic dinosaur fossils has aroused the author's deep thinking: "How can dinosaurs survive in Antarctica?" Dinosaurs didn't actually adapt to the cold climate. The author did not fix his thinking on the study of dinosaurs themselves, but linked this discovery with the Antarctic continent and asked him step by step: "Dinosaurs can't live independently on every land, so how did they cross the ocean to another continent?" In paragraphs 6 and 7, I gave a straightforward answer to this question: "The continent is drifting, not the dinosaurs themselves."
"There are many continents on the back of the plate. When the plate moves in one direction or the other, the mainland moves with it. " Obviously, some dinosaurs came to the South Pole on this "ship".
Paragraphs 8, 9, 10, 1 1 briefly introduce the "plate" theory and explain why there are dinosaur fossils on every continent. In the development history of more than four billion years, "How many times did Pan-continent form and split?" Because dinosaurs ruled the earth for too long, they only experienced a process of pan-continental merger and division, which became a witness to the history of geological evolution.
Pan-continent was first divided into four parts, and then most of them continued to split (only the Indian plate collided with the Eurasian plate to form a whole), so "each continent left with its own dinosaurs." This paper is helpful for readers to understand scientific concepts such as plate tectonics, mass extinction, collision theory, volcano theory and timeliness. This used to be a vibrant "boat of life", but because it sailed to the polar regions of the earth, it eventually turned into ice and snow, which led to the extinction of most of the creatures on this ship. Dinosaurs are the most prominent among them.
3. Cutting-edge technology tells the story of dinosaurs. Read the answer. Cutting-edge technology tells the story of dinosaurs. Dinosaurs ruled the earth for 654.38+65 billion years, from parrot dinosaurs, which were not much bigger than a chicken, to Lei Long, which is six stories high, occupying every piece of land in the world.
Since the 1970s, paleontologists have been telling us all the evidence of stories about dinosaurs' gender and family views in the media, and now they are re-examined with cutting-edge technology. We told all kinds of stories about dinosaurs, right or wrong, but no one exposed them anyway.
But it's different now. Sometimes the evidence is clear, just like a video. Another dinosaur bone was found in stegosaurus' stomach, which proved that stegosaurus was carnivorous.
The duck-billed dragon's stomach is full of pinecones, branches and pine needles, which undoubtedly proves that this dinosaur is a vegetarian. At the meeting of the American Geographical Society in April 1995, Hammer of Augustine College in Illinois reported the story of a large carnivorous dinosaur in Antarctica, which had two slender bones of an unknown creature in its mouth.
This dinosaur apparently died of accidental suffocation when using the last meal. These are simple findings.
Most puzzles about dinosaurs, such as color, intelligence, sound, birth and breeding, are still a mystery. But using new technologies such as anatomy, neuroscience and inferring evolutionary relationships, scientists can "enter the scene, collect evidence and complete some conclusions".
Speaking of the scene, footprints are one of the best evidences. Each dinosaur's footprints are completely different, some have canyon feet, and some have four feet, and from the footprints, sometimes we can judge the speed of dinosaur's marching or running. By studying the existing animals, we can find out the relationship between their pace and speed.
Putting this formula on dinosaurs, it can be roughly inferred that medium-sized carnivorous dinosaurs can run 43 kilometers per hour. Comparatively speaking, quadruped dinosaurs, armored stegosaurus and armed ankylosaurus walked slowly.
The path taken by dinosaurs is also good evidence that some dinosaurs lived in groups, just like zebras and elephants on the African plains. From a dinosaur path discovered in Texas, scientists found that there were 23 different pairs of dinosaurs walking 654.38+007 million years ago, only two of them were the same.
This shows that when dinosaurs can cross this path, they are arranged in a straight line vertically, led by the biggest one, rather than walking side by side. In another part of New Mexico, scientists found that 55 small herbivorous dinosaurs headed north and 25 large dinosaurs headed south. One of them is lame in one foot, but he can keep up.
It is common for large and small herbivores to act separately. Paleontologists use the bones of modern creatures to calculate the bones of dinosaurs.
Sometimes it's simple: dinosaurs with a row of sharp serrated teeth were carnivorous; Dinosaurs with smooth white teeth certainly ate grass. The muscles in dinosaur fossils sometimes provide good clues. The large muscles on Ankylosaurus' tail show that these guys often use their tails as swords to wave their prey.
Anatomy is a good way to explore the IQ and reaction ability of dinosaurs. For example, the brain often leaves many winding lines inside the skull. Some dinosaurs have complex brain lines, showing large and evolved brains, so they may have strong perception and memory ability; The brains of some dinosaurs have even evolved into features similar to those of birds.
The olfactory nerve cells of most dinosaurs are very small, but there are two dinosaurs with particularly developed olfactory cells, which shows that these two dinosaurs are not mainly hunting; Moreover, the eyes of these two dinosaurs are very small, indicating that their eyes are not very big, so it is not easy to see fast-moving prey, but their sense of smell can smell carrion thousands of meters away, so they live by eating leftovers from other dinosaurs. Of course, this theory is still controversial.
In fact, just by inferring the weight of dinosaurs, paleontologists will argue. One way is to use dinosaur bones plus imaginary muscles, blood and water to calculate.
They calculated that each brachiosaurus weighed about 87 tons. Another algorithm is to use the existing formula between the length, width and weight of animal bones to calculate that a brachiosaurus weighs 32 tons.
Crocodiles and birds are distant relatives of dinosaurs, and they both make sounds. If the evolutionary characteristics such as vocalization are the result of biological evolution, dinosaurs should be able to vocalize.
But this is just an inference. What paleontologists want to know most is the living habits of dinosaurs.
Although living habits can't stay in fossils, it's not entirely true. A carnivorous dinosaur found in Mongolia has a row of tooth marks, which are consistent with the upper row of teeth of the dinosaur, indicating that the dinosaur was killed by the same kind.
But the body was not eaten, indicating that the reason for being bitten to death was not for food. As for whether it is a vendetta or a love killing, it is difficult to find out from Conghua Stone.
From other angles, a series of other information can be deduced. As far as the horns of some dinosaurs are concerned, some horns were only generated when these dinosaurs were very old, which shows that horns are not tools for self-defense.
Fossils rarely have colors, so paleontologists can't answer whether dinosaurs were green, brown or orange. 13. The "cutting-edge technology" in the title refers to.
14. The underlined sentence in the second paragraph means. 15. By studying the existing animals, we can infer some data and characteristics about dinosaurs.
This research method is used in the study of dinosaur's' (), (), () and (). 16. The order of this article is.
17. The incorrect explanation in this article is () A. The smallest dinosaur is parrot dinosaur and the largest dinosaur is Lei Long. B. The language of this article is accurate and vivid, as can be seen from the title of the article.
C sauropods, stegosaurus and ankylosaurus can run at a speed of 43 kilometers per hour. D. Birds' brains are more developed than those who are afraid of being prostitutes.
E. Because fossils rarely have colors, it is impossible for cutting-edge technology to answer the colors of dinosaurs. 1. The "cutting-edge technology" in the title refers to new technologies such as anatomy, neuroscience and inference of evolutionary relationship.
All previous conjectures about dinosaurs were confirmed or denied by science and technology. By studying the existing animals, we can infer some data and characteristics about dinosaurs. This research method is used in the study of dinosaur's' (), (), () and ().

B.。
4. Why "Mr. Mantel is very skeptical about the identification of living in Ye Wei, and he thinks that the conclusion of living in Ye Wei is too hasty." Please find out the reason for your doubt in the article.
5. What can we learn from the mantel?
Answer: 1. Not serious, perfunctory. I am very happy to meet unexpected happy events. 2. A3.A. Due to road construction, rocks are * * *, and fossils in rocks may be found. Mrs mantel got into the habit of observing rocks and looking for fossils. These teeth and bone fossils were found in the same place and should belong to the same animal. Rhinos and hippos can't live in groups. Mantell "has seen many ancient animal tooth fossils, but none of them are similar to such a big and strange tooth", so Ju Ye Wei thinks it is impossible to convince Mantell that this is a rhinoceros tooth. First of all, we should learn from their love of science and strong curiosity. Secondly, we should learn from their spirit of not being superstitious about authority, persistently searching for answers and not giving up until we reach our goal.
Because it should be this.

5. David's dinosaur reading answer 1. Ask the family about the students' arguments. (1) Describe the movements and ways, and write down David's excitement and eagerness to show others after discovering dinosaurs.
(2) Expression description. Expressed David's pride and pride in his achievements.
The answer is not unique, as long as it conforms to the identity of the character and the situation at that time. What a lively discussion the children had! Isn't this what my educational thought wants to achieve? Let them express their opinions freely, and they will become more and more wise in constant debate and exploration! Because David thinks he is qualified to be a paleontologist.
Learning is a process of getting rid of the false and keeping the true. Only by overcoming difficulties and researching like David can we grow our talents in the learning process.
6. Rope Skills Read the original answer in classical Chinese.
In the mid-Kaiyuan period of the Tang Dynasty, a batch of gifts were given to Zhoujun. Jiaxing county competes with the producer for the best skills with 100 plays. The director is particularly interested. From the words of the prison people and the prison cloud: "The drama of the party is not as good as the county department, and we will bear it. However, those who wait for us but can do something small and considerable will reap money and sighs. " It's a matter of mutual consultation. As for the craft of making tiles, it's all about asking for help. A prisoner in the prison said with a smile, "If someone has clumsy skills, he is confined to the detention system and cannot show anything about it." The official was surprised and said, "What can you do?" The prisoner said, "I know rope skills." The official said, "Of course, I should speak for you." For the supervisor, this is as white as a prisoner can be. The Lord called for a heavy sentence, and the official said, "This prisoner is tired and has not suffered, and he wants nothing more." The official said: "There are always people who have rope skills. Why are they so unusual?" The prisoner said, "What a person does is slightly different from others." The official asked again, "How?" The prisoner said, "Everyone's rope skills are tied at both ends, and then they stand on it and turn around. Some people just want a rope, as thick as a finger, 50 feet, without tying it. You can do anything by throwing it in the air and tossing it around. " The official was surprised and ordered to be included. Tomorrow, officials will lead the theater. Since all the plays were made, I called this man for the second time to let the rope technique work. So he took a ball of rope, counted it 100 feet, put it on the ground, and threw one end in the air. The rope was as strong as a pen. At first, he threw three or two feet, then four or five feet, as straight as a person holding it, which surprised everyone. Then I threw it more than twenty feet high, and there was no end in sight. The man followed the rope hand, left the ground, and threw the rope away in vain, like a bird, flying far away and looking empty. Get out of the way, on this day.

During the reign of Emperor Xuanzong of the Tang Dynasty, the emperor issued several imperial edicts and ordered all counties to hold big banquets. Jiaxing county magistrate prepared a variety show to compete with more skilled supervisors. Prison officials are particularly eager to take part in the competition. At that time, the prison guard told the jailer: "If our juggling is worse than that in the county, we will be severely punished. If we can have a better one, we will be rewarded. Unfortunately, we can't do it. " They asked each other and began to look for talented people in prison. Someone who can make gadgets recommended himself. At this time, a prisoner in the prison smiled and said, "I'm a little clumsy, but I'm in custody now, so I can't show anything." The jailer asked in surprise, "What skills do you know?" The prisoner replied, "I know rope skills." The jailer said, "Well, I'll tell you something." So the jailer told the supervisor about the prisoner's talent. The supervisor asked the man how serious his crime was, and the jailer replied, "This man was dragged into the water by others, but he stole some taxes and nothing else." The prison official said, "Many people know rope skills. Is there anything particularly strange? " The prisoner said, "My rope skills are different from others." The prison officer asked again, "What's the difference?" The prisoner said, "other people's rope skills are to tie the two ends of the rope and then stand on the rope and walk or turn around." All I need is a rope, as thick as a finger and 50 feet long. No need to tie, no need to throw it into the air, prance and fly, no action I can't perform. "The prison officer was very surprised and asked to write down this person. The next day, the jailer took the prisoner to the theater, and other programs had already started, and then he was called to perform. I saw this man holding a rope ball more than 100 feet long, putting it on the ground and throwing a rope head into the air. The rope was straight. At first, I threw two or three feet, and then I got four or five feet. The rope was straight, as if someone was holding it, and everyone was surprised. Later, he was thrown more than twenty feet. When he looked up, he couldn't see the end of the rope, so the man held the rope in his hand and left the ground. Finally, he threw away the rope and flew higher and higher in the air like a bird. He took the opportunity to escape from prison that day.
