我从来没见过before 用it is 形式的；只见过it was /will be形式；能不能各举一个例子.其次,为什么这里不用when?
2.___ turn is ___ to clean the balckboard?
Whose ;that'
可是不是"it's sb's turn to do "的句型么?为什么后面一空用that而不是it；是答案错误么?
3.The seriously injured man has stopped breathing.____ will be no possibility of making him come to life.

选什么?以及其他几个为什么不可以?
回答一道也可以!

Answer 1

1：此句中,about已经体现了该句所说的将来的事情（将来时）:be about to do sth.将要做某事
2：理论上第二个空格可以用 it / this / that.可能是语境关系.不必深究
3：选B. 是there be 句型. There will be no possibility...字面翻译：那个严重受伤的人,已经停止了呼吸,将没有可能活过来
