问题 ______each smoke about 4,195 cigarettes a year.
Smoking has much to do with ______.

选项 A、the cancer of the throat
B、the cancer of the lungs
C、the cancer of the tongue
D、several kinds of cancers

答案D

解析 细节题。题干问:“吸烟和什么有很大关系?”文章第三段第一句说“大多数的研究人员认为吸烟和其他类型的癌症有很大关系”。可见吸烟不单单和某种癌症有关,它和很多种癌症都有很大关系。所以答案选D。
