单选题
It's good to know that the new software, which helps ______ programming time, keeps being developed.
(A) reduce
(B) reducing
(C) reduced
(D) reduces
【正确答案】
A
【答案解析】[理由] 本句测试动词help的用法: 1) help sb (to) V帮助某人从事…… [例] Kevin helped me write the letter. (凯文帮助我写这封信。) 2) help (to) V 帮助从事…… [例] She helped wash the dishes after dinner. (她晚饭后帮忙洗碗。) 根据上述,help之后有to引导的不定式短语作补语时,to皆可省略,保留之后的动词原形。原句空格前有helps,故知空格内应置入to reduce或reduce,因此(A)应为正选。
