问题 Doctors see a connection between increased amounts of leisure time spent ______ and the increased number of cases of skin cancer.

选项 A、to sunbathe
B、to have sunbathed
C、having sunbathed
D、sunbathing

答案D

解析 本题测试非谓语动词的用法。通过分析题意,我们知道spent及其宾语在此作后置定语,修饰先行词leisure time;而动词spend后面应用动名词作宾语,即spend doing sth.,故正确答案为sunbathing。
