Answer: (1) This picture shows the illumination of _ _ _ _ (southern hemisphere or northern hemisphere). (2) The date of this day is around _ _ _ _ _ _ (solar terms), which is too late.

(1) According to the principle that the earth rotates from west to east and from north to south, interpret the northern and southern hemispheres.

(2) Interpretation of solar terms according to extreme phenomena of day and night.

(3) The longitude of London is 0, which is the central meridian of the night hemisphere, so the local time is 0 o'clock.

Beijing time is in the East Eighth District, and when 0 is 0, it is 8 o'clock in the East Eighth District. Beijing is June 22nd, and the dates on both sides of 180 are different, and the dates on both sides of 0: 00 meridian (0) are different, so the same date as Beijing ranges from 0 to 180.

(4) The hemisphere where the direct point is located has a long day and a short night. The higher the latitude, the longer the day and the shorter the night. Because Beijing has a high latitude, the days are longer.

So the answer is:

(1) Northern Hemisphere

(2) Summer solstice, 23 26' north latitude or the Tropic of Cancer.

(3)0, 8? 0 east to 180 or 180 west to 0.

(4) less than
