Three small fish lived in the sea.When they were very young ,their parents died.
They had to __1___each other day after day.Finally, they grew up and __2____dared to swim deeper and further.
One morning the three fish were __3____ to a shallow(i&)water by a big wave(浪)。A small boat was taken there too.It was hard for the fish to go back to the sea because the boat was right in front of them.The largest fish realized that they were __4___ and said they had to find a way to leave there as fast as possible.The second largest fish ___5___with his elder brother, but the youngest one did not.He said that there was much ___6__ for them to swim, so he would not worry at all and still swam around ____7__At last, the largest fish returned to the ___8___ by jumping over the lowest part of the boat.The second largest fish also succeeded in ___9____ his elder brother in the other side of water.But the oungest one didn’t follow them and stayed in the shallow water.Two hours later, when the ___10_ rose up, the water in the small shallow corner dried up.The fish who did not try to return to the sea died of lack of water.

The idea of a fish being able to generate electricity strong enough to light lamp bulbs--or even to run a small electric motor--is almost unbelievable, but several kinds of fish are able to do this. Even more strangely, this curious power has been acquired in different ways by fish belonging to very different families.
Perhaps the best known are the electric rays, or torpedoes(电鳐), of which several kinds live in warm seas. They possess on each side of the head, behind the eyes, a large organ consisting of a number of hexagonal shaped cells rather like a honeycomb. The cells are filled with a jelly-like substance, and contain a series of flat electric plates. One side, the negative side, of each plate, is supplied with very fine nerves, connected with a main nerve coming from a special part of the brain. Current passes from the upper, positive side of the organ downwards, to the negative, lower side. Generally it is necessary to touch the fish in two places, completing the circuit, in order to receive a shock.
The strength of this shock depends on the size of the fish, but newly born ones only about 5 centime-tres across can be made to light the bulb of a pocket flashlight for a few moments, while a fully grown torpedo gives a shock capable of knocking a man down, and, if suitable wires are connected, will operate a small electric motor for several minutes.
Another famous example is the electric eel. This fish gives an even more powerful shock. The system is different from that of the torpedo in that the electric plates run longitudinally(纵向) and are supplied with nerves from the spinal(脊骨) cord. Consequently, the current passes along the fish from head to tail. The electric organs of these fish are really altered muscles and like all muscles are apt (likely) to tire, so they are not able to produce electricity for very long.
The power of producing electricity may serve these fish both for defence and attack.
It can be seen from the passage that().
A.the capacity to generate electricity is the distinctive characteristic of the fish
B.the current travels in an upward direction from the positive side to negative side in torpedo's electric cells
C.some fish can produce enough electricity to drive a number of electric motors
D.the torpedo' s electric cells have a shape with six sides
