20 12 June 23rd is a traditional festival in China-Dragon Boat Festival. Read the picture below to complete the question. Question 1: What is the longest day among the following traditional festivals in China?

Question 1:C

Question 2:B

Test analysis:

Question 1: China is in the northern hemisphere and the sun is in the northern hemisphere. China has long days and short nights. The sun shines directly on the Tropic of Cancer, and the days in China are the longest in a year. Around June 22, the sun shines directly on the Tropic of Cancer, the closest date is June 22, and the longest day. The date of Dragon Boat Festival is closest to June 22nd, and the longest day in China. So this question chooses option B.

Question 2: On June 23, the direct point of the sun was near the Tropic of Cancer, and the days in the northern hemisphere were long and the nights were short, which was close to the longest day in a year. In most parts of China, the solar altitude angle reaches its maximum at noon. So the temperature in our country is high, and it is summer. So this question chooses option B.

Comments: According to the position of the direct point of the sun, the position of the earth in the orbit of revolution, and the length of day and night in the northern and southern hemispheres, we can judge the solar terms of the earth. From summer to morning in the northern hemisphere (around June 22), the sun shines directly on the Tropic of Cancer, the days in the northern hemisphere are long and the nights are short, and the Arctic Circle and its north are extremely day. During the winter solstice (about 65438+February 22nd), the sun shines directly on the Tropic of Capricorn, and the days in the northern hemisphere are short and the nights are long, and the Arctic Circle and its northern region are extremely night. At the equinox, the sun shines directly at the equator, and the whole world is as long as day and night.
