A low-carbon(低碳) lifestyle has an effect our daily life. People are paying more and more attention to energies these days.

A. in; save

B. in; saving

C. on; save

D. on; saving

答案：

A. in; save

B. in; saving

C. on; save

(答案→)D. on; saving

解析：have an effect on sth.是固定结构，意为“对…有影响；对…起作用，产生效果”；pay attention to(注意)中的to是介词，其后接代词、名词或动名词。故选D，意为“低碳生活方式影响了我们的日常生活。近来人们越来越重视节约能源。”
