(1) From reading the map, we can see that ① is the Altai Mountains; ② is the Junggar Basin; ③ is the Tianshan Mountains; ④ is the Tarim Basin; ⑤ is the Kunlun Mountains; (2) Xinjiang’s topographic features are three mountains sandwiched by two basins , the three mountains refer to the Altai Mountains, Tianshan Mountains, and Kunlun Mountains, and the two basins are the Junggar Basin and the Tarim Basin.

(3) In the picture, A is the Irtysh River, flowing northward into the Arctic Ocean, and B is the Tarim River, the largest inland river in my country; (4) Xinjiang is located inland, far from The sea is far away. From a geographical point of view, the summer monsoon rich in water vapor has reached the end of its power after reaching the Hexi Corridor, and it is difficult to move toward the northwest. The vast northwest is a typical non-monsoon area with scarce precipitation and arid climate;

So the answer is: (1) Altai; Junggar; Tian; Tarim; Kunlun; (2) Three mountains sandwiched by two basins; (3) ) Irtysh; Arctic; Tarim; inland flow; (4) Xinjiang is located inland and far from the sea. From a geographical point of view, the summer monsoon rich in water vapor has reached the end of its power after reaching the Hexi Corridor. It is difficult to go northwest again. The vast northwest is a typical non-monsoon area with scarce precipitation and an arid climate;
