Passage 4

The three types of solar equipment used so far are the furnace, the still, and the cell. Solar furnaces heat water or air, providing a heat supply for a building. Some solar furnaces can produce temperatures as high as 7500 degrees Fahrenheit, which means that they can be used in industry.

Solar stills are especially important because they can provide fresh water fairly cheaply. They can rapidly take the salt out of sea water. One very simple type of still can also get small amounts of water from the earth – even in a desert.

The most highly developed and most useful type of solar power equipment is the solar cell. One of the cell’s biggest advantages is that it can be made small enough to carry. It can also be made large enough to produce enough power to run a car. Another advantage of the solar cell is that it has a very long life. It is still very expensive, but when ways are discovered to produce it more cheaply, it will be used very widely. （ ）46. A cell is a ____.

A. prison B. battery C. unit D. cave

（ ）47. A furnace ______.

A. takes salt from water. B. heats water or air. C. runs a car.

A. Solar furnaces can’t be used in industry. B. Solar cells are very cheap.

C. One type of solar still can get water even from the desert.

D. Solar still is the most developed and most useful type of solar energy equipment.
