Every animal is a living radiator-heat formed in its cells is given 【M1】______

through its skin. Warm-blooded animals maintain a steady temperature

by constantly replacement lost surface heat; similar animals, which have more 【M2】______

skin for every ounce of body weight, must produce heat faster than bigger

one. Because smaller animals burn fuel faster, scientists say they live faster. 【M3】______

The speed by which an animal lives is determined by measuring the rate at 【M4】______

which it uses oxygen. A chicken, for example, uses one-half cube centimeter 【M5】______

of oxygen every hour for each gram it weighs. The tiny shrew uses four cubic

centimeters of oxygen every hour for each gram it weighs. Because of it uses 【M6】______

oxygen eight times as fast, it was said that the mouselike shrew is living eight 【M7】______

times as fast as the chicken. The smallest of the warm-blooded creatures, the

humming bird, lives a hundred times as fast as an elephant.

There is no limit to how small a warm-blooded animal can be. A mammal or 【M8】______

bird that weighed only two and a half grams would starve to dead. It would 【M9】______

burn up its food too rapidly and would not be able to eat faster enough to supply 【M10】______

more fuel.

Man is the only animal that laughs. What is the history of this "happy laughter", as someo

ne once【67】it？

We are not【68】of theories to explain the mystery; researchers have been seeking a【69】explanation of laughter. One writer put【70】the theory that its function is to frighten others or to humiliate them. Another took the opposite【71】that we laugh in order not to cry. A psychologist offered the explanation that laughter【72】as a remedy to painful experiences and it serves to protect a person from【73】the psychologist called "the many minor pains to which man is exposed". In the seventeenth century a writer set forth the theory that we laugh when we【74】ourselves with others and find ourselves【75】to others; in effect, we laugh at the【76】of others.

Almost every theory has been【77】with either the structure or the function of laughter,【78】relatively few have been devoted【79】the question of its origin. I propose to offer a theory which has not previously been set forth,【80】only those animals capable of speech are capable of laughter; and therefore man, being the only animal that【81】, is the only animal that can laugh.

Those who have【82】chimpanzees(黑猩猩) closely feel confident that chimpanzees occasionally【83】behavior. that looks like a primitive human laughter. This【84】, however, has been observed only in a humanlike way; whether or not it is laughter is doubtful; the【85】fact that under any condition an ape is capable of【86】behavior. is no more than passing interest—it only indicates that early man might have the basic laughter.
