A Recent Erymology of the Word "Culture"“文化”一词的新词源

The civil (15) movement during this era brought everyone’s attention to bear on cultural differences within US society, while the Vietnam War (16) to emphasize the position of the US culture in relation to other world cultures.
Over time, these new uses (17) the word culture have eclipsed its older meanings, those associated with cultivation of the land and the production of (18) . You might say that an aspect of US culture over the past 40 years is its fascination with the (19) of culture itself—a fascination which has brought about many changes in the way we speak and the (20) of words which we commonly use.
