Question 2: A.

Question 3: D.

Test analysis:

Question 1: According to the distribution of isobars in the figure, the maximum atmospheric pressure in the figure is at the northernmost part of longitude 180, and its pressure value is between 1045- 1050; There are many places where the air pressure value is the smallest, and its air pressure value is between1005-1010. Therefore, the maximum difference of air pressure in the illustrated range should be between 35 and 45, and item B can be judged to be correct by comparing the four options. ?

Question 2: Although all the letters in the picture are in the center of air pressure, Z, X, P and N are in the center of low pressure, while Q and M are in the center of high pressure. Only in the center of low pressure can the letters in the picture rain.

Question 3: The latitude and longitude of Beijing is (116,40 n). According to the bending of the isobar on the map, it can be judged that the wind direction is southerly, so the five-star red flag on Tiananmen Square in Beijing will float to the north.
