单选题 Since most employees will be busy working in March to finish the project, they prefer that the company's picnic ______ until April.
  • A. postponed
  • B. be postponed
  • C. to postpone
  • D. postponing
【正确答案】 B
【答案解析】[解析] 语法：被动语态 1．that引导的从句主语是公司野餐会，原文意思是“野餐会被推迟”，应使用被动语态。因此B．be postponed为正确选项。 2．动词prefer引导从句时，从句要使用should+v原形，should可以被省略。即the company's picnic (should) be postponed。
