54、when congress reconvenes ,some newly elected members from rural states will try and establish tighter restrictions for the amount of grain farmers are to be allowed to grow and to encourage more aggressive sales of united states farm products overseas .
请问正确选项E:to establish tighter restrictions on the amount of grain farmers will be allowed to grow and to encourage ,
为什么主句已经有了一个谓语will try ....,后面怎么还跟了一个will be allowed ?怎么看也看不出原因,大家帮我看看, 谢谢了!!
