Culture means any human behavior that is learned in human society. All of the meaningful parts of a culture are passed on to different generations through tradition or social learning.  小题1:  Culture exists in agricultural as well as industrialized societies.

Culture is necessary for the survival and existence of human beings as human beings. Practically everything humans know, think, value, feel, and do is learned through taking part in a sociocultural system.  小题2:  Here is one of the cases of children growing up apart from human society. In the province of Midnapore in India, the director of a children’s home was told by local villagers that there were “ghost” in the forest. Upon looking into the case, the director found that two children, one about eight years old and the other about six years old, appeared to have been living a pack of wolves in the forest.  小题3:   In his diary, the director describes his first view of Kamala (as the older child was named) and Amala ( the name given to the younger child):

Kamala was a terrible-looking being, the head, a big ball of something covering the shoulders.  小题4:   Their eyes were bright and sharp, unlike human eyes. They were very fond of raw meat and raw milk. Gradually, as they got stronger, they began going on all fours, and afterwards began to run on all fours, just like squirrels.

Children learn human language in the same way they learn other kinds of human behavior——by taking part in a cultural community.   小题5: 

A．From this viewpoint, all human groups have a culture.

B．Close at its heels there came another terrible creature exactly like the first, but smaller in size.

C．Human beings can only develop human abilities by the local people.

D．This statement is well supported by some well-written cases.E. These children were the ghosts described by the local people.

F. Culture refers only to the high art and classical music of a particular society.

G. They learn a certain human languages as well as certain kinds of human behavior through their membership in a certain cultural community.
