Urgent!!! History experts come in!!

1. The country is falling apart.

2. Don't covet the feelings of power.

It's really hard for me to use a mobile phone, you go to the encyclopedia, there are what you want.

(1) Airplanes, tanks.

2) First of all, the progress of science and technology has made warfare more complicated, such as the first use of aircraft in World War I, which made air supremacy another important link in the war. Second, advances in science and technology have further expanded the scope of warfare, such as Japan's aircraft carrier attack on Pearl Harbor in World War II, followed by fighting in the entire Pacific Ocean. Third, the progress of science and technology is conducive to speeding up the course of the war, for example, the United States dropped the atomic bomb to successfully solve the problem of Japan, which was still stubbornly resisting.

Fourth, it will make the brutality of war even worse. For example, in the Battle of Verdun in World War I, the coalition forces used new ** tanks, and both sides lost a million people.

3) War promotes the development of science and technology, sometimes the two are carried out at the same time, and the impact of war on science and technology is very huge, but in the long run, it is a negative impact.

Hello. 1.Tanks, airplanes, long-range artillery, etc.

2.Hello, during the two wars, new types such as airplanes, tanks, long-range artillery, aircraft carriers, and atomic bombs appeared, which caused great lethality and brought great disasters to mankind.

3.War has a negative impact on the development of science and technology.

(1) Tanks, airplanes, poison gas.

2) The progress of science and technology when the tank appeared in World War I directly affected the combat form of the army in the future, and in the later army operations, tanks and armored units became the king of land warfare and directly affected the course of the war.

The development of radar and radio technology in World War II made the war three-dimensional and the scope larger. Information can be transmitted in real time between units and units, between the army and the air force, and between the air force and the navy, and air-ground integrated warfare will emerge.

3) war can objectively promote the progress of science and technology; However, war will have an adverse impact on the development of science and technology.

Contemporary history is generally inconclusive, and no one can say the historical significance of the future period. Of course not, China is getting stronger and stronger, hehe, it's not ! It is an inevitable process of social development! I do not know.

The classic tactics of the First World War, trenches, barbed wire, machine guns, and later the invention of mortars, were able to effectively hit soldiers in trenches. And the British invented a tank that could easily break through the trench blockade.

1.Radar, atomic bomb 2The influence of the two is mutual, science and technology promote the development of war, and war promotes the progress of science and technology. 3.Look again.

Born in the Qing Dynasty. Daoguang and Guangxu that section.

Question 2: No.

Question 3. Let's say it from my own point of view. If the population base is large, then in addition to the examination, the population base is small, and the method of cultivating professionals can be adopted.

China's Imperial Examination System The imperial examination system was implemented from the first year of the Great Cause of the Sui Dynasty (605) to the last Jinshi examination in the 31st year of Guangxu (1905) of the Qing Dynasty, which has gone through more than 1,300 years. Emperor Wen of Sui began to use sub-subject examinations to elect talents.

Positive aspects: breaking the hereditary system and rectifying the bureaucratic system; A large number of talented people have been promoted, discovered, and trained, and the employment system has been improved.

Negative aspects: because the rulers changed the content and form of the examinations, the imperial examinations became a shackle to the minds of intellectuals; Finally, the imperial examination system led to corruption in officialdom.

(1) From the feudal system to the feudalism centralized system; It laid the foundation for the great unified dynastic system in ancient China, which had a profound impact on Chinese politics and society for more than 2,000 years.

2) It prospers culture and education and promotes the fairness of examinations.

3) set up three divisions to weaken the power of the prime minister; The power of the monarch has been strengthened, and the power of the prime minister has been weakened.
