问题描述：
the students are discussing___a more meaningful holiday.A.how can they spend B.how will they spend
The students are discussing ___ a more meaningful holiday.
A.how can they spend
B.how will they spend
C.how they can spend
D.how they would spend
答案上写的是C
请问为何D不可以呢?
答
D 改成will就可以了啦。。。
整句意思是：学生们正在讨论他们如何能度过一个有意义的假日。
答
D是过去式，句子主从时态要一致。再加上would有表示虚拟语气的意图，指根本不可能发生的事情如果发生了会怎样，can在这里更为明确，表达更为直接。毕竟一个更有意义的假期还是可以发生的
答
因为是现在时
答
主句是现在进行时，从句不可能用过去将来时，这样，时态就不一致了；如果是how they will spend 一般将来时是可以的
不懂追问*^__^* 请采纳,谢谢！
答
would是过去式啊,
你看前面用的是are所以要用现在时
答
学生正在讨论要如何度过一个有意义的假期
是表示能力，用would 就是表示确定了
