B. are given
C. will be given
D. would be given
题目解答
答案
B. are given
解析
本题考查“unless”条件句的时态与被动语态的综合运用。解题核心在于:
- 主句与从句的时态关系:主句使用“will become”表示将来时,根据英语语法,“unless”引导的条件句需用现在时表将来。
- 被动语态的判断:句子强调“培训”是“被给予”给更多人,需使用被动语态(be + 过分)。
- 选项辨析:需排除不符合时态逻辑(如C、D项的将来时、虚拟语气)和语态错误(如A项完成时态)的选项。
时态逻辑分析
- 主句:“the problems of unemployment will become more serious” 使用将来时,表示假设的结果。
- 从句:“unless more men and women () the training” 通过“unless”引导条件,需用现在时表将来,因此从句动词应为一般现在时。
被动语态判断
- 句子逻辑是“培训”由他人“给予”(give),而主语“more men and women”是被动承受者,因此需用被动语态(be + given)。
选项辨析
- A. have been given:完成时态表示“已经被给予”,与句意“需要被给予”矛盾。
- B. are given:现在时被动,符合“除非被给予培训”的逻辑。
- C. will be given:将来时态与条件句的“现在时表将来”矛盾。
- D. would be given:虚拟语气,表示假设性情景,但句中未体现虚拟条件。
