Question 1:A

Question 2:B

This topic examines transportation and noise pollution, and examines students' ability to read and analyze pictures.

Question 1: The isoline axis is northwest-southeast. The dock is used for ships to enter and exit, and the noise isoline generated by ships should be centered on the port, and the axis direction is consistent with the river extension direction. The extension direction of the highway from point M to the north of the city is the same as that of the noise isoline axis, but the information in the figure shows that there is no southeast highway at point M, so it will not produce the extension direction of the isoline axis consistent with the graphic effect, that is, point M cannot be a bus stop. There is no railway passing through M, so it can't be a railway station, only an airport.

Question 2: The plane flies over the urban area, and the noise pollution affects the urban area. There are security problems and the layout is unreasonable. The direction of noise extension is northwest-southeast, so it can be judged that the direction of aircraft entering and leaving M is northwest-southeast.
