Analysis of test questions:

Question 1: You can read the pictures. From December 1 to 6, the provinces with the most serious haze weather were Jiangsu, Shandong, Hebei, Beijing, Tianjin and other nearby areas, so this question chose D.

Question 2: Haze is a weather phenomenon in which a large number of tiny dust particles, smoke particles or salt particles are suspended in the atmosphere, which makes the air turbid and reduces the horizontal visibility to less than 1km. As can be seen from the figure, the Yellow River Basin and the Yangtze River Basin are the heavy haze areas in China, followed by the Pearl River Basin, and the Songhua River Basin has the least number of haze days, so A is selected.

Question 3: Planting more trees and beautifying the environment can protect the environment and reduce smog weather; Factories discharge industrial waste gas, and dust generated in engineering construction seriously pollutes the air, which is not conducive to improving smog weather; The burning of garbage in life causes air pollution, which is not conducive to improving smog weather, so choose B.

Question 4: Pipeline is a modern transportation mode suitable for transporting materials such as liquids and gases. Its advantages are large transportation capacity, low freight rate, low loss, safety, reliability, strong continuity, convenient management, and being unaffected by meteorological disasters (such as smog and cold wave). However, it also has some disadvantages such as large equipment investment and poor flexibility. With the growth of oil and natural gas production, China's pipeline transportation has developed rapidly, so C is selected.

Question 5: Both the Yangtze River and the Yellow River originate in Qinghai Province. The abbreviation of this province is Qing, and the administrative center is Xining, so B is chosen.

Question 6: China is located in the eastern hemisphere from the eastern and western hemispheres; Seen from the northern and southern hemispheres, it is located in the northern hemisphere; China is located in the east of Asia and the west bank of the Pacific Ocean. China's territory spans a wide latitude from north to south, most of which are located in the mid-latitude area, belonging to the north temperate zone, and a few areas in the south are located in the tropics south of the Tropic of Cancer, and there is no frigid zone. The option ACD is incorrectly described and does not meet the meaning of the question, so B is chosen.

Question 7: China is an important maritime power in the world. From north to south, the adjacent seas are Bohai Sea, Yellow Sea, East China Sea and South China Sea in turn, so choose A.

Question 8: China's topography is high in the west and low in the east. Most rivers in China flow from west to east and flow into the Pacific Ocean, such as the Yangtze River, the Yellow River and Heilongjiang. Choose B according to the meaning of the question.

Question 9: The Beijing-Shanghai line runs from Beijing to Shanghai, so during the winter vacation, Xiaoming took a train from Beijing to Shanghai to visit relatives. The railway line he passed was the Beijing-Shanghai line, so he chose A.
