Schools across China are expected to
Schools across China are expected to hire 50,000 college graduates this year as short-term teachers,almost three times the number hired last year,___ reduce unemployment pressures.
A.help B.to have helped C.to help D.having helped
,为什么不能选D呢?我在等待您的答案

to do ……是目的状语.
D选项语法上没错.但是,意思上有两点不对.
第一,school across China are expected to hire 就是中国的学校希望可以……,说明这是个计划,还没有执行或者正在执行中,肯定没有执行完.如果执行完了,那么它不会说 are expected to hire ,而D选项是个现在完成时,是说已经解决了失业压力.这是不合理的.
第二,V+ing 做伴随状语,一般是用来说,主要的怎么怎么样,同时（Ving）怎么怎么样.就是随着主要事件发生的还发生着什么.是这样的感觉.
