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。
