Read the schematic diagram of the earth's revolution and answer the following questions (1). Mark the direction of the earth's rotation with arrows in the picture. (2) When the earth revolves to position B, it happens to be in the north. (1) The revolution direction of the earth is from west to east.

(2) When the earth revolves to position B, the sun shines directly at the equator, which coincides with the vernal equinox in the northern hemisphere, and the time is around March 2 1.

(3) When the earth revolves to position C, the sun shines directly on the Tropic of Cancer, which coincides with the summer solstice in the northern hemisphere, and the time is around June 22nd, with the longest day and the shortest night in Ziyang in the northern hemisphere.

(4) When the earth revolves to position D, the sun shines directly at the equator, which coincides with the autumn equinox in the northern hemisphere, and the time is around September 23rd; When the earth revolves to position A, the sun shines directly on the Tropic of Capricorn, which coincides with the winter solstice in the northern hemisphere, and the time is about 65438+February 22; Therefore, when China's Shenzhou VIII spacecraft was launched in space at 20111. At that time, the earth was in orbit around the sun, roughly running between the above-mentioned AD. So option d fits the question.

So the answer is: (1)

(2) vernal equinox; Equator; (3) The days are long and the nights are short; (4)D。
