Because forests generally have a low albedo, (the majority of the ultraviolet and visible spectrum is absorbed through photosynthesis), some scientists have suggested that greater heat absorption by trees could offset some of the carbon benefits of afforestation (or offset the negative climate impacts of deforestation).

main Urban anthropology
Urban anthropology is concerned with issues of urbanization, poverty, and neoliberalism. Ulf Hannerz quotes a 1960s remark that traditional anthropologists were a notoriously agoraphobic lot, anti-urban by definition. Various social processes in the Western World as well as in the Third World (the latter being the habitual focus of attention of anthropologists) brought the attention of Anthropology#Focus on the other cultures specialists in other cultures closer to their homes.<ref name=Hannerz/> There are two main approaches to urban anthropology: examining the types of cities or examining the social issues within the cities. These two methods are overlapping and dependent of each other. By defining different types of cities, one would use social factors as well as economic and political factors to categorize the cities. By directly looking at the different social issues, one would also be studying how they affect the dynamic of the city.<ref> cite journal doi=10.1177/1466138110370412 jstor=24047982 title=Chinese consumers: The Romantic reappraisal journal=Ethnography volume=11 issue=3 pages=331–357 year=2010 last1=Griffiths first1=M.

我在Jupyter Notebook中编程。谢谢。
第一个代码段的问题是，作为参数传递给HTTP调用的文本太长，如果您打印响应对象，则会看到：
[<Response [414]>对应于414 URI Too Long Reference] >>
如果传递较小的文本，则dbpedia-spotlight将能够为您注释实体。
对于您输入的第二个代码，您有两个问题，第一个是dbpedia-spotlight在连续调用注释服务后可能会以403状态响应，以检查是否建议您这样做：
r = requests.get(url=REQUEST, headers=HEADERS) if r.status_code == requests.codes['ok']: . . .另一个可能发生的问题是，如果您所请求的文本中未添加任何注释，则响应中将没有
Resources键，因此，为解决此问题，建议您使用get()函数，而不是：
resources = response['Resources']您将拥有：
resources = response.get('Resources', [])这样，您输入的第二个片段的最终代码将是这样：
