Passage 3
Questions 31 to 35 are based on the following passage:
The idea of a fish being able to generate electricity story 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 (电鱼), of which several kinds live in warm seas. They possess on such 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 pan 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 centimeters 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 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 defense and attack. 31. 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
32. Usually you will not get a shock by touching the electric ray in one place only because __________.
6
A. the current in one place is not strong enough to give a shock B. the fish’s electric cells are filled with jelly-like substance
C. to complete the circuit, you have to touch the fish in two places D. a torpedo’s electric cells contain more than one electric plates 33. The main idea of the third paragraph is that _____________.
A. a mature torpedo is capable of producing enough electricity to knock down a man B. the mass of the fish decides the intensity of electric power it generates
C. the strength of shock given by a young electric ray can only light the bulb of a pocket flashlight
D. to make full use of the energy produced by electric fish, suitable wires should be available
34. The reason why the electric eel is able to give more powerful shock is that
________________.
A .the working system of the electric plates in the eel is the most effective
B. the working system of the electric plates in the eel is far inferior to those in the torpedo
C. compared with those in the torpedo, the working system of electric plates in the eel is more direct and efficient
D. compared with other electric fish, the eel possesses much more electric plates 35. The ideal title for this passage is _____________.
A. The Eel B. Torpedo C. Electric Fish D. Electric Power
Passage 4
Questions 36 to 40 are based on the following passage:
Computers may one day turn night into day—with good old, natural sunlight.
Colossal computer-controlled mirrors, thousands of feet across, may one day orbit the earth, reflecting sunlight onto a darkened United States.
Some scientists say that 16 of these mirrors, each about half a mile across, could aim their reflected light at one area on the earth that was about 200 miles by 300 miles. That much light would equal about 56 moons.
The mirrors would be so high that they could catch the sun's light as it was shining on the other side of the earth. The mirrors could orbit-thousands of miles high—at the same speed as the earth turns on its axis (轴). That way, the mirror could always be over the same spot.
The aluminum-coated (涂铝的), plastic mirrors could be folded up and packed into a spaceship, according to the scientists. Once released a few hundred miles in space, the mirrors, powered by a solar-powered engine, could make the rest of the trip into space on their own.
The scientists say the computer-controlled mirrors could also be made to tilt (倾斜) slowly, so the reflected sunlight would sweep slowly along the surface of the earth. For example, as night fell, the mirrors could be tilt to light up Boston. Later on, as darkness spread slowly

westward. Chicago, for example, then San Francisco could be lit up. The reflected sunlight would allow these cities to save up electricity. And in emergencies, such as power-failures, the mirrors could light up the affected area.
What no one knows yet is what effect this artificial daytime would have on plants, animals, and humans. Would it confuse some animals and harm some plants that are used to the day-night circles? The scientists recommend that studies be done to find out what the effects there might be.
36. The word \
A. nuclear-powered B. orbiting C. giant D. spinning 37. Which of the following is NOT TRUE of the mirrors?
A. They would be made of plastic and coated with aluminum. B. They could be launched into space directly.
C. They would stay in the same position over the earth.
D. They could reflect the sunlight to a large area on the earth.
38. The reflected sunlight could sweep slowly over the surface of the earth because the mirrors __________________.
A. would be operated be solar-powered engine
B. would orbit thousands of miles high to catch the sun light
C. could move around the earth at the same speed as the earth turns on its axis D. could be made to adjust their angles
39. The purpose for turning night into day is to_________. A. confuse animals and plants B. light up more cities
C. save energy and deal with emergencies D. enable people to work longer hours 40. The writer of this passage________.
A. gives an objective account of the mirrors
B. seems to be much worried about the effects of the mirrors C. is in favor of wide use of the mirrors
D. suggests that the artificial daylight is harmful to living being
