Common indoor plants may prove to be a valuable weapon in the fight against rising levels of indoor air pollution. Those【C1】______in your office or home are not only【C2】______, but NASA scientists are finding them to be【C3】______Useful in absorbing potentially harmful【C4】______and cleaning the air inside modern buildings.
NASA and the Associated Landscape Contractors of America(ALCA)have【C5】______the findings of a 2-year study that【C6】______the common indoor plant may provide a natural way of helping【C7】______"Sick Building Syndrome."
Research【C8】______the use of biological processes as a means of solving environmental problems, both on the【C9】______and in space habitats(栖息地), has been【C10】______out for many years by Dr. Bill Wolverton,【C11】______a senior research scientist at NASA’s John C.

选项
A、quickly
B、expectedly
C、surprisingly
D、disappointingly
答案
C
解析
此处缺少修饰useful的副词。quickly不能修饰形容词useful;植物洁化空气这一作用与其装饰作用相比,是科学家的新发现,并且是一个积极的作用,所以不能选择expectedly和disappointingly。因此答案是surprisingly。
