In the 1960s, many young Americans were dissatisfied with American society. They wanted to end the Vietnam War and to make all of the people in the US equal. Some of them decided to "drop out" of American society and form their own societies. They formed utopian communities, which they called "communes", where they could follow their philosophy of "do your own thing". A group of artists founded a commune in southern Colorado called "Drop City". Following the ideas of philosopher and architect Buckminster Fuller they built dome shaped houses from pieces of old cars. Other groups, such as author Ken Kesey’s Merry Pranksters, the followers of San Francisco poet Steve Gaskin, and a group that called itself the Hog Farm, lived in old school houses and traveled around the United States. The Hog Farm became famous when they helped organize the Woodstock Rock Festival in 1969. Steve Gaskin’s followers tried to settle down on a farm in Tennessee, but they had to leave when some members of the group were arrested for growing marijuana.
Not all communes believed in the philosophy of "do your own thing", however. Twin Oaks, a commune founded in Virginia in the late 1960s, was based on the ideas of psychologist B. F. Skinner. The people who lived at Twin Oaks were carefully controlled by Skinner’s "conditioning" techniques to do things that were good for the community. In 1972, Italian architect Paolo Soleri began to build Arcosanti, a utopian city Arizsona where 2,500 people will live closely together in one large building called an " archeology". Soleri believes that people must live closely together so that they will all become one.

A.They were not satisfied with American society.
B.They wanted to grow marijuana.
C.They wanted to go to the Vietnam War.
D.They did not want all people to be equal.

在卢旺达,香蕉是最重要的农作物之一。人们把它生着吃、炸着吃、烤着吃,甚至将其酿成香蕉酒。但是,在每年种植的200万吨香蕉中,其实只有很少一部分——果肉——真正为人所用,剩下的香蕉皮、叶子和枝干只有白白烂掉这一条出路。英国诺丁汉大学的科学家们日前想出了一个办法,只借助很少的工具和技术,以及非洲充沛的日照,就可以将香蕉皮和叶子制成可持续提供稳定热源、满足烹饪与取暖需求的香蕉炭砖。

通过上文,我们可以知道的是()。

A.卢旺达的主食是香蕉

B.果肉不能制成香蕉碳砖

C.现代复杂的科技可以变废为宝

D.通过一定条件,香蕉皮也可以作为新能源
