Read the temperature and precipitation data of Laizhou, and complete. 1 month, April, July,1October annual temperature (℃)-3.312.125.75438+05.76438+02.3 precipitation (mm) 8.

(Solution: (1) Draw the annual variation curve of temperature (℃), mark the temperature data of each month in the data with points, and then connect these points with smooth curves to draw a curve, that is, the annual variation curve of temperature; Finally, the monthly precipitation in the data is marked with a rectangular histogram and painted with the same color. (2) Reading the map, we can see that the lowest temperature in our city appears in 65438+ 10, and the highest temperature appears in July, and the annual temperature in the whole year is 29℃. (3) As can be seen from the table, the annual temperature change in our city is characterized by hot summer and cold winter. The seasonal variation of precipitation is characterized by more precipitation in summer and less precipitation in winter.

So the answer is: (1), as shown in the figure:

(2) 1; 7; 29;
