问题 Why is New Delhi’s air polluted so seriously in November?
In New Delhi, the smog was at its worst in November, 2019. Government officials have taken steps to control the pollution. They stopped work at construction sites and limited the number of cars that were allowed on the road. But experts said, this wasn’t likely to have a major effect on the smog because a lot of it came from outside New Delhi. Around the time of year when temperatures drop, India’s farmers light fires to get rid of leftover crops. That produces a lot of pollution that settles over New Delhi.

选项 A、Smog forms as temperature drops.
B、There is little rain this time of year.
C、Farmers set fire to the leftover crops.
D、There is a lot of construction going on.

答案C

解析 根据新闻定位句可知,每年气温下降的时候,印度农民就会生火来清理剩余的庄稼,这造成了大量的污染,笼罩在新德里上空。故选C。
