b Interpretation: "Spring breeze" refers to the "summer monsoon" in climatology, which is the warm and humid southerly air flow blowing from the ocean.

Yumen Pass is surrounded by mountains, the terrain is also very undulating, the tall mountains and some basins of different sizes form a complex geographical environment, and the climate has obvious continentality. Its western part is embraced by the Pamir Plateau, blocking the warm and humid air flow from the Atlantic Ocean. The southern part is connected to the Tibetan Plateau, blocking the warm and humid air flow from the Indian Ocean. There are also some famous mountain ranges to the southeast (such as Helan Mountain), which also block the warm and humid air flow from the Pacific Ocean. The warm and humid air flow here is actually the summer monsoon - spring breeze.

The summer monsoon comes from the ocean and is not only warm, but also humid. In the areas where the summer wind blows, the precipitation rate generally increases, and the plant growth is relatively lush. However, the strength of the summer monsoon is weak, the speed of invasion into the interior is relatively slow, and the impact time is also shorter, especially in the northern part of China, which is controlled by the summer monsoon for a shorter time.

Every year between April and May, the summer monsoon reaches the southern coast of our country; Arrived in the Yangtze River basin in June; It was not until July that North China and Northeast China were promoted; In September, it was forced by the northern winter winds, so it quickly withdrew to the south of the Yangtze River. In terms of climatology, the areas in China that are obviously affected by the summer monsoon are called monsoon areas; The area that is not significantly affected by the summer monsoon is called the non-monsoon area. The specific boundary is probably bounded by the famous mountain range of Daxing'an Mountains-Yinshan-Helan Mountain-Bayankala Mountain-Gangdis Mountain.

According to this boundary, Yumen Pass happens to be in the non-monsoon zone, so the summer monsoon - spring breeze will not blow Yumen Pass.

First of all, analyze from the willow.

The poplar willow mentioned here is mostly represented by Populus euphratica, which is suitable for the warm temperate desert climate between 10 and 2000 and 4 500 with an accumulated temperature of more than 4000, and grows best in the warm temperate desert rivers and floodplains with an accumulated temperature of more than 4000.

Outside the Yumen Pass, the Gobi still occupies the main plant during the Tang Dynasty, and in the spring and summer, the Indian Peninsula will form an Indian high, which can be affected by the summer monsoon in the northwest of China. Therefore, here the spring breeze should refer to the summer monsoon.

Seven (71%) ocean, three (29%) land.

1.No.

2.Learning to change destiny. Self-improvement, constantly master new knowledge, new skills 3Yes Through study, such as participating in amateur training, self-study exams, professional training, etc., you can master some skills and work hard to achieve success.

4.It is not luck that changes fate, but knowledge. As long as you participate in more part-time training, self-study exams, professional training, etc., master some skills, and through hard work, you will definitely succeed in the end!

Conditions for the development of agriculture in Australia.

Nature: The climatic conditions are good, the terrain in the central region is flat, and there is ample water supply.

Socio-economic: vast and sparsely populated, convenient transportation, high degree of mechanization, advanced level of agricultural science and technology.

Australia's main development is mixed agriculture, that is, wheat --- sheep herding business model, the central part of Australia has a tropical desert climate, which is not conducive to agriculture and animal husbandry, but the climatic conditions in other regions are more superior. The distribution of agriculture and animal husbandry in Australia is mainly distributed in the southeast and southwest.

Conditions for agricultural development in the Great Plains of the central United States.

Plain terrain, open terrain, vast and sparsely populated, conducive to mechanization and large-scale production; Summers are warm and humid, with abundant water sources and convenient irrigation; The soil is fertile; The transportation is developed and the market is broad; The level of science and technology is high, the industry is developed, and the degree of mechanization is high.

From this, we can get the corresponding option C

Due to the influence of the Great Dividing Range in Austria, the precipitation in the central Great Plains is not abundant, and the water for animal husbandry is transferred from the eastern part of the Great Dividing Range across basins.

c bar Australia doesn't seem to have abundant precipitation, a lot of deserts...
