时态:It____to store this glass,which the nuclear waste was turned into,in deep underground mines.
It____to store this glass,which the nuclear waste was turned into,in deep underground mines.A.is plannedB.would be planned答案是A.後面不是过去时was嘛?

It is planned to do .按计划.,就像我们学过的短语 it is said that.据说.
如果使用过去式,应该是It was planned to store.
通常使用现在时和过去式.但是B选项是过去将来时.
