Last on the weekend, fei Man's captain is taking us to go for an outing. The captain is driving a car, we gallop on highway, the scenery of road both sides but beautiful, the cascade of mountain range layer of far is folded, field and woods stretch to the horizon, we are singing a song all the way, good expect to reach destination quickly.
Abrupt, blame auspicious cries greatly, "Look quickly, there is a river in front. " we look down his finger, there is a brook as expected in front, green hill inverted image is on surface, beautiful all the more, then everybody shout is worn should go down to play.
It is by the side of the river, we take a picture each other, be not auspicious to was not patted only, I see him one buttock sits on the ground, begin a shoe to come, go by to ask him then: "Blame auspicious, are you doing what? Are you doing what??
Blame auspicious takes off a shoe to say at the same time at the same time: "I should enter the water catch a fish, you look, the fish in this water but much, wait for it is OK still to meet us the move that bake eats. Wait for it is OK still to meet us the move that bake eats..

Blame auspicious one face distains taking off a sock to say " how likely, see benthic, this river arrives at most my crus. This river arrives at most my crus..
I look at surface also very feel puzzled, right, look at really very shallow, the appearance that the fish of benthic stretchs his hand to be able to be caught. How is this to return a responsibility? Still ask Fei Man the captain first.
Fei Man's captain listened to me to say reason, say " actually ah, you were cheated to your eye. You were cheated to your eye..
Original, the light crosses surface to be able to produce reflection, the eye that lets us receives erroneous information.
We feel the brook is very shallow, because light of river bottom catoptric crossed water,be, in the eye that refracts us again, view the past according to radial direction, those who see is the virtual image that be refracted through surface and becomes actually, the position of virtual image can want than real river ground tall, accordingly, can feel water is shallow.
So, see when us clear the river that sees an end, but must not rushed go down, lest produce risk.
