First, light and shadow are the magicians of nature.

Shadow is an optical phenomenon. Because the object blocks the propagation of light, it cannot pass through the darker area formed by the opaque object, which is what we often call the shadow.
Second, ordinary outdoor dining tables and chairs, because of the cooperation of light and shadow, are so mysterious at this moment!
Third, there are always people who do things that even you don't dare to think about.
Fourth, the sun shone on the car; "The truck in front of us, and we said 'HI' all the way."
Fifth, I didn't expect that the flames would have no shadow under the light.
Flames are luminous bodies that emit light in all directions, and there is no shadow without obstruction.

Bull-nosed ray is a large fish with a width of more than 2 meters between the pectoral fins. It is famous for the long-distance migration of large groups. In the Atlantic, the ox-nosed ray usually migrates north in late spring and back south after autumn. In the Gulf of Mexico region, flocks of migrating ox-nosed rays can reach more than 10,000 at the most, swimming clockwise from western Florida towards the Gulf of Mexico near the Yucatan Peninsula.
The migration time of the bull-nosed ray can be up to 2 years.

Thirteen, this gentleman who works, skateboards to work, the technology is absolutely first-class.

(Two crows fight black cats and white cats.) )
