The following figure shows the weather situation in some regions of China, and the dotted line in the figure is the isobar (unit: hectopascals). Read the picture and complete the following questions. Question 1: About China at this time

Question 1:D?

Question 2:C

Analysis of test questions:

Question 1: Reading the picture, judging from the distribution position of the air pressure center, the northern part of China is controlled by cold high pressure, which is not in most parts of the country, nor is it rainy. How sunny the high pressure control should be? A is wrong. China has a monsoon climate, which destroys the influence of the subtropical high zone. B is wrong. Judging from the air pressure center in the figure, the cold front has not reached South China, and there is no precipitation weather on the front. C is wrong. According to the distribution position of the pressure center, there is a trough of low pressure in the northeast, which forms a cold front and brings rainy weather.

Question 2: The main function of GPS is positioning and navigation, and it cannot be used for mapping. Remote sensing, mainly measuring and recording, is a distant perceptual target, which can collect information. Geographic information system is the collection, processing, storage and analysis of geographic information, which can be charted. Digital Earth uses digital methods to convert all the information on the earth into data, so as to realize the circulation and * * * sharing on the network. It is impossible to draw maps, and it is wrong. So c is right. A, b and d are wrong.
