4. (Multiple choice) The following description of Chengdu is incorrect:
A. The political and cultural center of the western part of our country
B. Famous Historical and Cultural City of China
C. Transportation and communication hubs in the western region
D. National Pilot Zone for Coordinating Urban-Rural Comprehensive Supporting Reform
In the first step, this question examines human geography knowledge and selects the wrong item.
The second step, Lanzhou, referred to as "Lan" or "Gao", ancient known as Jincheng, is the capital of Gansu Province, the State Council approved and identified as an important industrial base and comprehensive transportation hub in northwest China, one of the important central cities in the western region, and an important node city in the Silk Road Economic Belt. The transportation and communication hub in the western region is Lanzhou, not Chengdu.
So, choose the C option.
Item A: Chengdu, a sub-provincial city in Sichuan Province, referred to as Rongcheng, also known as "Rongcheng, Jincheng", is the capital of Sichuan Province, a sub-provincial city, a megacity, the seat of the organs of the Western Theater, an important national high-tech industrial base, a commercial and trade logistics center and a comprehensive transportation hub determined by the State Council, and an important central city in the western region. Item A is correct, but it does not fit the meaning.
Item B: Chengdu is a national historical and cultural city and the birthplace of ancient Shu civilization. King Tai of Zhou was named Chengdu after "one year chengyi, two years Chengdu"; there were 7 separatist regimes to establish the capital here. Item B is correct, but it does not conform to the meaning of the topic.
Item D: The National Coordinated Urban-Rural Comprehensive Reform Pilot Zone is a state-level comprehensive supporting reform pilot zone established by The National Development and Reform Commission on June 7, 2007 to approve the establishment of Chongqing And Chengdu. Item D is correct, but does not fit the idea.
5. (Multiple choice) One of the following idioms that corresponds to historical figures is:
A. Broken Cauldron - Xiang Yu
B. Single knife to the meeting one by one Guan Yu
C. Refers to the deer as a horse - Zhao Gao
D. Self-made - white
In the first step, this question examines literary common sense and selects the wrong items.
The second step is the metaphor of self-made people relying on themselves without foundation and poor conditions, and working hard to start a business. From the Zhuzi Language Class, vol. 107: "The master of the present shi started in the white house, so that he was honored." The Zhuzi Language Class is a compilation of quotations from Zhu Xi and his disciples' questions and answers. In the Song Dynasty, Li Jingde was arranged in a class, and published in the sixth year of Xianchun as the 140-volume "Zhuzi Language Class", which is now the popular version of "Zhuzi Language Class". It can be seen that starting from scratch has nothing to do with whiteness.
Item A: Breaking the cauldron and sinking the boat means breaking the rice pot and sinking the ferry. The parable leaves no way out, you must win the battle, and you are determined to do it to the end at all costs. In 209 BC, a peasant uprising led by Chen Sheng and Wu Guang broke out in China's history. After the death of Chen Sheng and Wu Guang, the two armies led by Liu Bang and Xiang Yu gradually grew. In 207 BC, Xiang Yu's rebel army fought a major battle with the main force of the Qin army led by the Qin general Zhang Handan at Julu (julu, in present-day Xingtai, Hebei), and Xiang Yu was not afraid of the strong enemy and led his troops to cross the Zhangshui River (a river flowing from the northeast of Julu to the southeast). After crossing the river, Xiang Yu ordered the whole army: "All shipwrecks, break the cauldron, burn the hut, and hold three days of food, so as to show that the soldiers will die, and none of them will return their hearts." "The giant deer fought a battle, the Qin army was broken, and the Xiang soldiers threatened the princes." It can be seen that the allusion of breaking the cauldron and sinking the boat is related to Xiang Yu. Item A is correct.
Item B: Single knife to the meeting, which means that Guan Yu originally brought only one knife and a few retinues to Lu Su's banquet. Later, it refers to a person who ventures to an appointment. There is a sense of praise for the wisdom and boldness of the participants. In 215, Liu Bei took Yizhou, and Sun Quan ordered Zhuge Jin to ask Liu Bei for Jingzhou. Liu Bei did not agree, and Sun Quan was extremely annoyed, so he sent Lü Meng to lead an army to take the three counties of Changsha, Lingling, and Guiyang. Changsha and Guiyang Shu will surrender immediately. When Liu Bei learned of this, he personally rushed from Chengdu to The Gong'an (present-day Hubei Gong'an) and sent the general Guan Yu to compete for the three counties. Sun Quan also immediately entered Lukou and sent Lu Sutun to defend Yiyang to resist Guan Yu. The two sides were tense, and Sun Liu's alliance was facing rupture, and at this critical juncture, Lu Su, in order to maintain Sun Liu's alliance and not give Cao Cao an opportunity, decided to negotiate with Guan Yu in person. "Su invited Yu to meet each other, and each soldier and horse were stationed on a hundred steps, but the generals met with one sword." After talks, the two sides eased tensions. Subsequently, Sun Quan and Liu Bei agreed to divide Jingzhou equally, "cutting the Xiangshui river as a boundary, so as to strike the army", so that Sun Liu's alliance could continue to be maintained. It can be seen that the allusion of shan dao going to the meeting is related to Guan Yu. Item B is correct.
Item C: Refers to a deer as a horse, which means referring to a deer and saying that it is a horse; the metaphor deliberately reverses black and white and confuses right and wrong. During the reign of Qin II, Zhao Gao traveled with a deer with him, and the second asked him, "Why is the chancellor driving a deer?" Zhao Gao said, "This is a horse!" The second said, "The prime minister is wrong, and he has treated the deer as a horse." Zhao Gao said, "This is indeed a horse!" (If) His Majesty thinks that what I have said is wrong, he hopes (His Majesty will allow me) to ask the courtiers. "Half of the courtiers said it was a deer, and half said it was a horse. Under these circumstances, the King of Qin could no longer insist on his own views and had to obey Zhao Gao's words. It can be seen that the allusion of referring to deer as horses is related to Zhao Gao. Item C is correct.
6. (Multiple choice) In daily life, we are exposed to some folk proverbs, which contain a wealth of physical knowledge. The following folk proverbs and colloquialisms reflect phenomena that have nothing to do with physical knowledge:
A. Planting melons to get melons, planting beans to get beans
B. Real gold is not afraid of fire refining
C. Frozen three feet, not a day's cold
D. People go to the high place, and the water flows to the low place
In the first step, this question examines the knowledge of physical chemistry and selects the wrong item.
The second step, "Plant melons to get melons, plant beans to get beans" means what to plant and what to harvest. The parable does what is done and what kind of results are obtained. It reflects the same traits between parents and offspring, so it embodies the genetic phenomenon of biology, which has nothing to do with physical knowledge, and item A is correct.
Item B: "Real gold is not afraid of fire refining" is from Haoran's "Sunny Days", which is a metaphor for people with good quality and strong will who can withstand any test. Gold is the least metallically active, and does not react with oxygen even at high temperatures. Gold is a solid metal at room temperature, and when it is burned in the air to the melting point, gold is the only metal that does not change color, does not oxidize, and has almost no weight loss. Related to physical knowledge, item B error.
Item C: "Frozen three feet, not a day's cold" The surface meaning is that it is frozen three feet, which is not the effect that can be achieved by a day's cold. Water freezes and freezes below 0 °C, related to physical knowledge, C item error.
Item D: "People go to a high place" is to indicate people's ambition and pursuit, people's nature is upward, is to constantly improve themselves, climb to a high place, and develop to a good place. "Water flows downwards" is a natural objective law. Under the action of gravity, the water will naturally flow downwards, related to physical knowledge, D item error.

Item C: Second-generation ID cards and bus cards use contactless smart cards with radio frequency identification technology. Item C is correct.
So, choose the BC option.
Item A: GPS collects the observation data and information of each monitoring station by the ground main control station and locates it through satellite. Item A error.
Item D: The two-dimensional code is expanded on the basis of the one-dimensional code, after being scanned by the device, the information contained in it can be obtained, and the two-dimensional code has a "fault-tolerant mechanism" that the two-dimensional code does not have - even if the two-dimensional code is perforated or defaced, or even the damaged area is up to 50%, the information can still be recovered. Strong fault tolerance and error correction ability, which makes the two-dimensional code can still be correctly identified when it is partially damaged due to perforation, defacement and other reasons, and the damaged area can still be restored by 50%. Item D error.
8, (single choice) The resources in the universe are huge, and the development of cosmic energy resources mainly refers to the development of:
A. Electrical energy
B. Solar energy
C. Wind energy
D. Geothermal energy
Correct answer: B
In the first step, this question examines cutting-edge scientific and technological knowledge.
In the second step, solar energy is the radiation energy from the sun produced by the fusion of hydrogen helium in the hydrogen atoms inside the sun and releasing huge nuclear energy. The vast majority of the energy humans need comes directly or indirectly from the sun. Solar energy resources are the richest permanent energy resources in the universe and the most important resources developed by human beings.
So, choose option B.
Item A: Electrical energy refers to the ability of electricity to do work in various forms. There are DC power, AC power, high frequency power and so on. Item A error.
Item C: Wind energy is the kinetic energy of air. On the earth and in the atmosphere, the solar radiation energy received and the long-wave radiation energy emitted everywhere are different, so the temperature is also different everywhere, which causes a difference in air pressure. Item C error.
Item D: Geothermal energy is natural heat energy extracted from the Earth's crust, which comes from lava inside the Earth and exists in the form of heat, which is the energy that causes volcanic eruptions and earthquakes. Item D error.
9. (Multiple Choice) The following description of the application of genetic engineering is correct:
A. Gene therapy is to induce defective genes into normal genes
B. The basic principle of genetic diagnosis is DNA molecular hybridization
C. A genetic probe can detect various viruses in water bodies
D. Prokaryotic genes cannot be used for genetic improvement of eukaryotes
In the first step, this question examines biomedical knowledge.
In the second step, nucleic acid molecular hybridization is one of the most basic methods of genetic diagnosis. The basic principle of genetic diagnostic technology is that complementary DNA single strands can bind into double strands under certain conditions, that is, they can be hybridized. This binding is carried out strictly according to the principle of base complementarity, and it can be carried out not only between DNA and DNA, but also between DNA and RNA. Therefore, when a probe is made with a nucleic acid sequence of a known gene and comes into contact with the denatured single-stranded genomic DNA, if the bases of the two are perfectly paired, they are complementarily bound into a double strand, thus indicating that the genome UNDER test contains a known gene sequence. It can be seen that there are two necessary conditions for genetic testing, one is the necessary specific DNA probe, and the other is the necessary genomic DNA. When both are denatured in a single-stranded state, molecular hybridization can be performed.
Item A: Gene therapy refers to the introduction of foreign normal genes into target cells to correct or compensate for diseases caused by defective and abnormal genes, so as to achieve the purpose of treatment, so that the products made by foreign genes can treat a certain disease. Gene therapy refers to the introduction of foreign normal genes into target cells, rather than inducing defective genes into normal genes. Item A error.
Item C: A gene probe, or nucleic acid probe, is a sequence of nucleic acids (DNA or RNA) with a detection marker and a known sequence that is complementary to the gene of interest. Gene probes combine with the gene of interest through molecular hybridization to produce hybridization signals that can display the gene of interest from the vast genome. A genetic probe can detect a virus. Item C error.
Item D: Prokaryotic genes can be used for genetic improvement of eukaryotes Now many genetically modified organisms are hybridized with genes of prokaryotes to produce new varieties. For example, insect-resistant cotton. Item D error.
10. (Single choice) The rivers with the richest hydropower reserves in China are:

13. (Right or Wrong) Archery, calligraphy and driving all belong to the ancient "six arts". （ ）
A. Correct
B. Error
The first step is to test cultural knowledge.
In the second step, the ancient "six arts" refer to the six basic talents that ancient Confucians in China required students to master: ritual, music, archery, imperial court, book, and number. Etiquette is etiquette, music is music, archery is archery technology, imperial driving (carriage) technology, books are calligraphy, and numbers are algorithmic techniques.
Therefore, this question is correct.
14. (Right or Wrong) Huashan is located in Hunyuan County, Datong City, Shanxi Province. （ ）
In the second step, Huashan is located in Huayin County, Shaanxi, relatively close to Xi'an.
Therefore, this question is incorrect.
15. (Right or wrong) After mosquito bites, use soapy water to relieve itching because soapy water has weak acidity. （ ）
In the first step, this question examines the knowledge of physical chemistry.
In the second step, when mosquitoes bite people, they leave something called formic acid in the human skin, and formic acid is very irritating, making people feel that the skin is itchy. Soapy water is an alkaline thing, after being bitten by mosquitoes, applying soapy water can "neutralize the reaction" with formic acid under human skin, and people will no longer itch.
16. (Multiple Choice) Computer networks enhance many of the functions of personal computers, but what cannot be done at present is:
A. Resource sharing and mutual communication
B. Improve reliability and availability of letters
C. Eliminate computer virus infection
D. Transfer data bills between banks and businesses
In the first step, this question examines the knowledge of computer networks and selects the wrong item.
In the second step, the development of computer networks has greatly facilitated people's lives, but with it the invasion of viruses. In order to prevent computer virus infection, a large number of antivirus software has emerged. Antivirus software, also known as anti-virus software or anti-virus software, is a type of software used to eliminate computer threats such as computer viruses, Trojan horses, and malware. Antivirus software typically integrates monitoring and identification, virus scanning and removal, automatic upgrades, proactive defense, and more. Antivirus software can reduce virus intrusion, but it cannot kill all viruses, and it cannot eliminate computer virus infection. Item C was wrong, but it was in line with the title and was elected.
Item A: Computer network refers to a computer system that connects multiple computers with independent functions and their external devices with different geographical locations through communication lines to achieve resource sharing and information transmission under the management and coordination of network operating systems, network management software and network communication protocols. Item A is correct, but it does not correspond to the meaning of the topic and is not elected.
Item B: Load balancing refers to the work being evenly distributed to each computer system on the network. The network control center is responsible for distribution and detection, and when a computer is overloaded, the system will automatically transfer the load to a lighter computer system to deal with it. It can be seen that the computer network can greatly expand the functions of the computer system, expand its application scope, improve reliability, provide convenience for users, but also reduce the cost and improve the performance-price ratio. Item B is correct, but it does not correspond to the meaning of the topic and is not elected.
Item D: Data communication is a communication method and communication service that uses data transmission technology to transmit data information between two terminals in accordance with a certain communication protocol. The information transmitted in data communication is expressed in the form of binary data, and another feature of data communication is that it is always associated with remote information processing, which is a generalized information processing including scientific calculation, process control, information retrieval and so on. Computer networks enable data bills to be passed between banks and businesses. Item D is correct, but does not correspond to the meaning of the topic and is not elected.
17. (Single choice) Meteorological disasters are one of the natural disasters, mainly including typhoons, droughts, high temperatures, flash floods, thunderstorms, sandstorms, etc. The following meteorological disasters correspond to the areas in which they occur, and one of the errors is:
A. Typhoon - The eastern coast of Guangdong and Hainan
B. Sandstorms - North China
C. Floods - Southeast coastal areas
D. Drought - South China
In the first step, this question examines the knowledge of physical geography and selects the wrong item.
In the second step, in March and April of each year, the warm and humid air flow on the southern ocean surface began to move north, and continuous rainfall occurred in China from south to north, producing plum rain in the south. However, if this air flow is too strong, the control range of the rain stationary front will soon be pushed to the Yellow River Basin, and the middle and lower reaches of the Yangtze River will be mainly controlled by the subtropical high pressure in the western Pacific Ocean, forming an anti-cyclonic weather, and the following sinking air currents are dominant, and because of the long sunshine, the solar radiation is very strong, the temperature is high, the evaporation is exuberant, and the drought is generated, so it is not South China. Item D is wrong, but it is in line with the idea.
Item A: China is located on the west coast of the Pacific Ocean, because the western Pacific typhoon has the characteristics of moving in the northwest direction, so China is extremely vulnerable to typhoons. Typhoons occur mainly from mid-summer to early autumn. Typhoon disasters are mainly distributed in the southeast coastal areas. Item A is correct, but does not meet the meaning of the topic when excluded.
Item B: Due to (1) dry climate, loose and dry soil in North China, wind erosion of soil is becoming more and more serious. (2) Under the growing pressure of the population, people have destroyed forests and deforested forests indiscriminately, resulting in a decrease in forest coverage. (3) Driven by economic interests, overgrazing and indiscriminate digging of medicinal materials in the upwind areas have led to the rapid degradation of forest grasslands and the continuous expansion of desertified land areas, resulting in frequent sandstorms. Item B is correct, but does not conform to the meaning of the subject, when excluded.
Item C: Flooding refers to the phenomenon of submerging and waterlogging low-lying areas due to heavy rain, heavy rain or continuous rainfall. According to historical rain and flood statistics, the most serious areas of rain and flooding are mainly the southeast coastal area, the Xianggan area, and the Huai River Basin, and item C is correct, but it does not meet the meaning of the topic, and should be excluded.
18. (Right or Wrong Question) The Nanshan in the Zhushou language "Shoubi Nanshan" refers to the Sanya Nanshan. （ ）
In the second step, the word Nanshan comes from the Book of Poetry, Xiaoya Tianbao: "Like the eternity of the moon, like the rise of the sun, like the life of Nanshan." "Shoubi Nanshan, which means that the life span is as long as the Zhongnan Mountain, is used to celebrate the elderly." Therefore, Nanshan Specifically refers to the Zhongnan Mountain south of Xi'an City.
Zhongnan Mountain, also known as Taiyi Mountain, Zhongnan Mountain, Zhou Nanshan Mountain, referred to as Nanshan, is the birthplace of "Dao Culture", "Buddha Culture", "Filial Piety Culture", "Shou Culture", "Zhong Kui Culture", "Fortuna Culture", "Shoubi Nanshan" and "Zhongnan Shortcut" and other allusions, located in the middle of the Qinling Mountains in Shaanxi Province, and is an important geographical indication in China.
19. (Right or Wrong) Corn was introduced to China through the Silk Road. （ ）
In the first step, this question examines the knowledge of Chinese history.
In the second step, corn is native to the Americas. Corn has long been the staple food crop for native Americans. Corn was introduced to China in the late Ming and early Qing dynasties. Regarding the route of transmission, academics generally believe that there are three ways for corn to be introduced to China: (1) northwest land introduction: first from Spain to Mecca, and then from Mecca through the Silk Road in Central Asia Minor to northwest China; (2) southwest land introduction: first from Europe to India, Myanmar, and then to southwest China. (3) Southeast sea route introduction: first from Europe to Southeast Asia, through Chinese merchants or Portuguese from the sea to the southeast coastal areas of China. However, from the reliable evidence, corn is likely to be introduced to Yunnan from India and Myanmar. And not through the Silk Roads.
Corn was introduced to China in the 16th century. Native to Central and South America, Columbus brought Brazilian corn seeds back to Spain in 1494 and gradually spread throughout Europe; with the discovery of the Great Discovery of Geography, american corn spread around the world by 1550. At present, domestic scholars generally believe that the introduction of American corn into China began in the early 16th century, flourished in the 19th century, and flourished in the 20th century.

In the second step, Zhao Fu, the ninth emperor of the Southern Song Dynasty and the last emperor of the Song Dynasty, reigned for two years, only 8 years old, and Han Lin'er was honored as Emperor Huaizong Gongwen Ningwu Mourning Emperor Xiaoxiao. In April 1278, he ascended the throne as emperor in Gangzhou and changed his name to Yuan Xiangxing. On March 19, 1279, the Song and Yuan carried out a decisive battle at the Battle of Yashan, the Song army was defeated by the Yuan army, the whole army was destroyed, the Yuan army then surrounded The Yuan army surrounded The Shame of Jing Kang was about to repeat itself, and at Yashan Mountain (present-day Xinhui Yamen) in Guangdong, the 8-year-old Zhao Fu jumped into the sea and died, and the 100,000 soldiers and civilians of the Southern Song Dynasty in Yashan also threw themselves into the sea and martyred the country, and the Song Dynasty collapsed. From this, it can be seen that "the eight-year-old little emperor Song Yu was killed by Lu Xiufu who jumped into the sea on his back." "Item B was in line with the idea and was therefore elected.
Item A: Wen Tianxiang, first name Yunsun, the word Song Rui, and the word Lushan. Luling people of Jizhou, Jiangxi, politicians, writers, patriotic poets, famous anti-Yuan courtiers and national heroes, together with Lu Xiufu and Zhang Shijie, were known as the "Three Masters of the Late Song Dynasty". Item A did not meet the title and was therefore not elected.
Item C: Xin abandoned the disease, the original word Tanfu, later changed to the word You'an, jiaxuan, Shandong East Road Jinan Province Licheng County people. The Southern Song Dynasty was a poet and general, known as the "dragon in words". Together with Su Shi, he was called "Su Xin" and "Jinan Er'an" with Li Qingzhao.
