It can be concluded that a concentration of carbon dioxide in the atmosphere would ______.
the article was written to explain ______.
选项
A、the models of solar-weather interactions
B、the causes affecting weather
C、the greenhouse effect
D、the solar effects on the earth
答案
B
解析
主旨题。文章从二氧化碳引发温室效应入手,然后说明了地球变暖的后果和这一过程中的一些矛盾现象,并在第五段提出了主旨问题:哪个自然因素对天气影响最大,然后着重分析了太阳的影响。由这些内容不难看出,文章的主旨当然是说明影响天气的一些原因。其他三项都只是文章的部分内容,不能作为全文主旨。
