Human beings are animals. We breathe, eat and digest, and reproduce the same life （1）common to all animals. In a biological laboratory, rats, monkeys, and humans seem very much the same.However, biological understanding is not enough: （2）itself, it can never tell us what human beings are.（3）to our physical equipment — the naked human body ― we are not an（4）animal. We are tropical creatures,（5）hairless and sensitive to cold. We are not fast and have neither claws nor sharp teeth to defend ourselves. We need a lot of food but have almost no physical equipment to help us to get it. In the purely physical（6） our species seems a poor （7） for survival.But we have survived-survived and multiplied and（8） the earth. Some day we will have a（9）living on the moon, a place with neither air nor water and with temperatures that turn gases into solids. How can we have done all these things? Part of the answer is physical. （10） its limitations, our physical equipment has some important （11） We have excellent vision and hands that can（12）objects with a precision unmatched by any other （13）. Most importantly, we have a large brain with an almost （14） number of neural （15） .We have used this physical equipment to create culture, the key to our survival and success. If we live in the Arctic, we supply the warmth our tropical bodies need （16） clothing, shelter, and（17） heat. If a million people want to live in a desert that supplies natural food for only a few hundred, we find water to grow food and（18） deficits by transporting supplies from distant places. Inhabitants of our eventual moon colony will bring their own food and oxygen and then create an artificial earth environment to supply necessities. With culture, we can overcome our natural limitations.It was not always （19）. Our distant ancestors were just animals, faced with the limits of their physical equipment. They had no （20）and lacked the physical capacity to use it.

Since about 1800,near the beginning of the Industrial Revolution, coal, petroleum, and gas have been used at a rapidly increasing rate. The supply of these（1） is limited, and electric power is very （2） in many places. Some scientists believe solar energy is the only （3） which can meet the world’s enormous（4）for power.Great progress had been made in harnessing the sun. Not only is the sun now used in cooking, （5） it also supplies power for （6） things as beacon lights for ships and airplanes. It（7）telephone lines, portable radios, electric clocks, hearing aids, and even communication. Some homes and office buildings in the United States are now being（8）with solar energy.The three most significant types of solar equipment（9） are the furnace, the still, and the cell. Solar furnaces heat water or air,（10）is then circulated through a building to make it comfortable.Solar stills are （11） important because they can provide （12） water at a relatively cheap rate. Salt can easily be （13） from sea water with a solar still.The most highly developed type of solar （14） equipment is the solar cell. Some cells are so （15）that they can turn 16 percent of the energy they receive from the sun（16） electric energy. One of the cell’s biggest advantages is （17）it can be made either small enough to carry（18） large enough to produce a current that can run an automobile. Besides, it has a very long life. It is still too expensive for the （19）consumer but when ways are （20）to produce it more cheaply, we can expect its use to be wide-spread.
