It was a problem whether they would support us. 他们能否会支持我们还是一个问题。

四、连词 that 的省略问题
指引主语从句的连词
that 有时可省，有时不可以省，其原则是：若 that 指引的主语从句直接
位于句首， 则 that 不可以省略； 若 that 指引的主语从句位于句末， 而在句首使用了形式主语 it ，
则 that 可以省略：
That you didn ’ t go to the talk was a pity. 很遗憾你没去听报告。
(that 不可以省 )
(that 可省 )
It was a pity (that) you didn ’t go to the talk. 很遗憾你没去听报告。
