外刊例句
In the last half-century or so, more than half a million Detroit trees died from disease and neglect. At the same time, the city underwent dramatic demographic shifts. By 2016, Detroit was 82 percent African-American and had the highest percentage of low-income residents in the country. As a result, it was primarily low-income African-American communities who were forced to deal with the consequences and the hazards, like falling limbs, posed by dead trees.
在过去的半个世纪左右,底特律有50多万棵树死于疾病和疏于打理。与此同时,这座城市也经历了巨大的人口变化。截至2016年,底特律人口中有82%都是非裔美国人,低收入居民比例是美国最高的。因此,像树枝掉落等由树木枯死造成的后果和危险,基本上不得不由低收入非裔美国人社区来应对。

追根溯源
单词demographic里的词根demo,来源于希腊语dēmos, 表示“人民”。所以,包含词根dem/demo的单词,多与此相关,例如:
democracy n. 民主
epidemic n. 传染病;流行病
pandemic n. 流行病,瘟疫
demography n. 人口统计学
这个词根在韦小绿《Vocabulary Builder》Unit12中也有详细解读:
