The main advantages of agricultural production in the underground are that the underground is in a constant temperature state, which can achieve year-round production, prolong the growth period, and improve production; At the same time, because it is isolated from the ground, it can reduce diseases and pests, reduce pollution, and achieve green production.
So choose C.
anti collapse D.
D Japan is located at the junction of the Eurasian plate and the Pacific plate, with frequent crustal movements and earthquakes.

Complete 1 ~ 3 questions accordingly.
However, due to the very tight land resources and limited agricultural production space, some cities will be conducive to agricultural production in underground air raid shelters.
The main disadvantage is that the factory has a large amount of construction work in the early stage, the factory is difficult, and the investment is large.
The storage of raw materials and products on the ground and underground is not much different, and the underground space is relatively small; The construction cost of underground factories will increase, which is not conducive to reducing costs.
Opal was accidentally found here in the early stage.
For example, a laser processing machine assembly enterprise in Gifu, Japan, and a CNC machine tool processing enterprise in Dalian, China have built their factories 10 meters below the ground.
Today, we know about the “underground buildings” mentioned in the college entrance examination questions.
In the ground environment, high-tech enterprises choose areas with beautiful environment to reduce the adverse impact of the environment.
① ④ D.
Because the climate here is dry and hot, workers dug caves underground to live in order to avoid the harsh climatic environment while excavating gemstones, and slowly formed an underground city.
At the same time, because it is hidden underground, on the one hand, it saves land resources, on the other hand, it enhances its confidentiality.
Temperature or humidity changes will have a great impact on it.
Due to the development of vertical joints in loess, it is very suitable for excavation of caves..
Compared with Gifu, The problems less considered in the design and construction of Dalian underground factory are a.
Building the factory below 10 meters underground is similar to a cave, which can maintain a constant temperature environment and reduce the impact of ground vibration.
B according to the first question, building the factory producing precision mechanical equipment underground is conducive to maintaining a constant temperature environment and reducing the impact of ground vibration.
Illustration: written at the end: this topic tests the candidates’ understanding and analysis of the location of enterprises with special requirements by building factories underground through some enterprises in Japan and Dalian, China.
The underground constant temperature and humidity environment, which is less affected by ground vibration, provides an excellent production environment.
② ④ 2.

So choose D.
Underground factories generally produce precision instruments or confidential military equipment underground.
① ③ B.
02 underground farms are densely populated in cities and have a large demand for agricultural products.
At the same time, precision mechanical equipment has high requirements for quality, so the direct purpose is to ensure product quality.
The following group of questions is a group of questions in 2018 national Volume 1, which has been raised to underground factories.
anti earthquake 3.
The production of precision instruments and equipment has very high requirements for the natural environment.
03 underground city Cooper Pedy in Australia is the only underground city in the world.
In the case of limited and decreasing surface space resources, looking up and down for development space is an important way for human beings.
So choose D.
We have selected some materials in the college entrance examination questions as the background to introduce some relevant geographical knowledge to you.
Living in the underground city is cooler, but the disadvantages are also obvious, the ventilation conditions are relatively poor, and the echo is relatively obvious.
For example, the largest underground production factory in Asia – the underground “machine tool kingdom” of Dalian Guangyang technology group, this special factory is located 14 meters underground, with an area of 15000 square meters.
So what are the common ways of life and production of human beings carried out underground? What are the advantages and disadvantages of underground construction? [2018 national Volume 1] in recent years, there has been a phenomenon that assembly or processing plants of precision machinery and equipment are built underground in the world.
The college entrance examination questions basically take a certain geographical phenomenon or process in a certain region as the background to examine the relevant geographical knowledge, ability and literacy.
Its disadvantages mainly include: first, the underground lighting conditions are poor, which requires long-term artificial lighting to promote photosynthesis of plants, increasing the energy cost; Second, poor ventilation conditions; Third, there is a lack of soil, so it is generally carried out in the form of hydroponic culture.
to ensure product quality C.
it is inferred that the direct purpose of the above enterprises to build the factory underground is A.
Building the factory producing precision mechanical equipment underground is conducive to ① maintaining a constant temperature environment ② storing raw materials and products ③ reducing production costs ④ reducing the impact of ground vibration a.
Later, a large number of people entered the area to excavate opal.
In this process, because the materials selected for the college entrance examination questions are relatively typical and distinctive, the college entrance examination questions are also an important window for us to understand the world.
Another example is the 816 underground nuclear project in early China, which was also produced underground.
The purpose of industrial production is to obtain profits, ensuring product quality is conducive to increasing profits, and others are not its direct purpose.
to meet the needs of war preparedness D.
It focuses on the location factors of small angle analysis of industrial layout and relevant knowledge of plate motion.
to enhance the degree of confidentiality B.
3.
intensive use of land reference answer: 1, C 2, D 3, B analysis: 1 C the production of precision machinery and equipment has high requirements for the environment.
Other issues need to be considered.

② ③ C.
(Note: we don’t want everyone to talk so much to students, because it will never be finished, but as a popular science or expansion to understand.).
